Activia Review- Does This Probiotic Yogurt Work?
All dieters are tired of trying time and again to lose weight only to fight a losing battle with an ineffective supplement. My love of diet products is only bested by my passion for reviewing them 🙂 We decided to focus on ingredients, side effects, scientific studies and customer service quality for Activia. Furthermore, we read through hundreds of dieter experiences and comments. Then, we summarized and refined to give you the info you need.
What is Activia?
To start, Activia is a probiotic yogurt containing bifidus regularis, reduced fat milk, peach puree, fructose, sugar, water, whey protein concentrate, corn starch, modified corn starch and kosher gelatin.  You can eat throughout the day, supposedly helping with regularity. The small cups makes it easy to take on the go. 
Activia was initially released by Dannon in 1987 and appears to contain some natural ingredients. It’s found in local grocery stores and you have several flavors to choose from. We like the longevity of the company and that we found some favorable customer comments, but read on…
Ineffectiveness – “Uh Oh!”
The first concern was the ineffectiveness of Activia ingredients.  “Yogurt typically contains good bacteria which supposedly helps with digestion,” said our Research Editor. “If customers eat the Activia for the recommended two weeks and nothing happens, this is concerning.”
- “For about 2 years, I ate Activia. It didn’t help with my extremely slow digestive system and major constipation issues,” stated a dieter.
- “I purchased Activia with the belief it would help my digestive system, only to find out that it did not,” reported another.
We did find some who appreciated the results.
- “There were some bumps in the road but after about 3 or 4 weeks I leveled off with a bowel movement or 2 every day and much less bloating and never any stomach cramps,” one user said.
- Another shared, “‘I love how Danon Activia gives me a bowel movement daily.”
Adverse Effects With Activia – “Yikes”
Some customers have complained of Activia side effects.
- In fact, one user said, “I recently tried Activia yogurt because it states it can cure your tummy troubles in two weeks. On the 5th day pain started stomach area.”
- “Unable to expel gas and pooh for days, it has led me to discontinue its use completely,” claimed another person.
We did find some people who noticed a change for the positive.
- “After about a week my stomach problems stopped,” offered one user.
- As another put it, “I have not suffered any negative side effects, in fact I no longer am so gassy and bloated.”
The research we’ve done has shown if there is a particular aspect of a diet product that is especially bothersome, like negative side effects, the likelihood of prolonged weight-loss success is minimal. If Activia does in fact lead to adverse reactions, this could be a major problem. 
Here at DietSpotlight, we like to see documented clinical research that backs the diet product and its ingredients.  In regards to Activia yogurt, we did not find any scientific studies presented on the official website stating the product helps you lose weight. While there are plenty of claims that this yogurt helps promote regularity and digestive health, there does not appear to be backing for weight-loss. 
The Bottom Line – Does Activia Work?
Before you race through the grocery store to the dairy aisle, let’s take one more look at this one. We like that Activia contains some natural ingredients and that the price seems reasonable, but we have concerns about this one because the research doesn’t point toward weight-loss.  We’re also a bit hesitant due to customer talking about negative side effects and ingredients not working. 
If you want to lose those extra pounds, we suggest going with a supplement consisting of some clinically-tested ingredients and no reports of adverse reactions.
Among the best products we’ve seen this year is one called Dietspotlight Burn. This weight-loss supplement contains some clinically-tested ingredients that have been shown to help ignite metabolism and accelerate fat loss. We have not seen any complaints of side effects and user reviews posted on the web indicate people are seeing excellent results.
We find it shows great confidence that the makers of Dietspotlight Burn are offering a special trial offer, which is a good sign.
Activia is a probiotic-rich yogurt that claims to help improve digestive health with regular use. There's no doubt that probiotics are a healthy addition to most diets, but proof does not exist that says this brand is better than any other source of healthy bacteria.

Other Ingredients: Kosher gelatin, milk protein concentrate, agar agar, vitamin D3, calcium lactate, guar gum, lactic acid, natural vanilla flavor, sodium citrate
We dug deep into the Activia ingredients to give you the details you need. Ingredients may vary slightly depending on the flavor and type of yogurt. Some use Greek yogurt that has more protein, and others have added fiber.
Reduced Fat Milk
Milk with some of the natural fat removed and replaced with water.
What is it Supposed to Do?
It is the base of yogurt, and is supposed to provide the nutrition of milk without all the fat and calories
According to a study published in Livestock Production Science, “Many theories were based on the concept that reduced milk fat was a consequence of a limited supply of lipid precursors, e.g. the insulin-glucogenic theory; experimental data provide little support for this concept as the basis for diet-induced MFD [milk fat depression].”
Sugar is a natural sweetener, but contains no nutrition.
What is it Supposed to Do?
It sweetens the flavor of whatever it is added to.
According to a study published in Clinical Nutrition & Metabolic Care, “There are now convincing evidences for enhanced cardiometabolic risk after higher intake of SSB [sugar sweetened beverages] where both epidemiological studies and human intervention studies are pointing in the same direction. A so-called ‘well tolerated’ intake of SSB is not determined. Accordingly, intake of SSB should generally be reduced as much as possible to improve the health of the population.”
Fructose is naturally occurring sugar found in fruits.
What is it Supposed to Do?
It is the sugar inside the fruit that makes it sweet.
According to a study published in The American Journal of Clinical Nutrition, “In addition, fructose, compared with glucose, is preferentially metabolized to lipid in the liver. Fructose consumption induces insulin resistance, impaired glucose tolerance, hyperinsulinemia, hypertriacylglycerolemia, and hypertension in animal models. The data in humans are less clear.”
Water is essential for human life.
What is it Supposed to Do?
It provides hydration and helps make the yogurt formula.
Modified Food Starch
This is a chemically altered ingredient made from starch. It’s manipulated to remove gluten.
What is it Supposed to Do?
It thickens the yogurt.
Gelatin that’s not been derived from a pig.
What is it Supposed to Do?
It will thicken the formula, but may help with skin, hair, and nails, joints, and improve digestion.
A vegetable protein.
What is it Supposed to Do?
Agar is used to thicken foods.
This is a fiber that comes from the seed of the guar plant.
What is it Supposed to Do?
It is supposed to treat digestive issues like diarrhea and IBS. It may help reduce cholesterol and produce a laxative effect.
This is a compound that’s made when the body breaks down sugar and oxidizes it.
What is it Supposed to Do?
It is formed when the yogurt ferments.
This mineral is naturally found in milk.
What is it Supposed to Do?
It’s supposed to prevent calcium deficiency.
Vitamin D3 is a naturally occurring vitamin, but is often added to milk and other products because it’s only found in small amounts in a few foods.
What is it Supposed to Do?
It is used to treat a number of conditions, such as osteoporosis, heart and blood vessel issues, obesity, and muscle weakness.
This is an antacid.
What is it Supposed to Do?
It’s supposed to reduce the acidic nature of foods.
The results of my research into Activia were somewhat surprising. We’ll take a 360-degree look into Activia ingredients. Our attention will turn toward the formula, concentrating on scientific studies. We’ll also examine hundreds of customer comments. Then, we’ll summarize the info to give you the bottom line.
What You Need to Know
To start, Activia is yogurt containing milk, bifidus regularis, water, modified food starch, inulin, acacia gum, modified corn starch, kosher gelatin, pectin, natural flavors, carmine, sodium citrate, malic acid, sucralose, calcium lactate, xanthan gum, acesulfame potassium, among others. The recommended serving is one cup daily for two weeks, which supposedly improves digestive health. You can consume the product on the go, one benefit.
The product, first introduced by Dannon in 1997, appears to contain some natural ingredients, a good choice. You can shop for it at local health food and grocery stores. We like that the company has been operating for more than 15 years and that we found some favorable customer comments, but read on…
Sugar Content – “Too Much Sweetness?”
The first concern about Activia ingredients related to taste. “Dieters often complain that they can’t eat the sweets they once did when trying to lose weight,” said our Research Editor. “In this case, the opposite problem seems to take over.”
“I hate it!!!! Doesn’t have any good stuff on it. It is so sweet, fake sweet and so gross,” said a user.
“I only tried it once after reading the ingredients list, which told me that not only is the product not vegetarian (contains gelatin), it is also loaded with sugar and unnecessary additives! I will never eat this product again, and will go back to eating plain yogurt that contains only milk and organic cultures,” offers a dieter.
FTC Judgments and Lawsuits – “False Claims?”
The Federal Trade Commission reached a settlement with Dannon about exaggerated claims with Activia. The FTC stated the company had to stop saying, “that one daily serving of Activia relieves irregularity…” The business was charged $21 million.
Side Effects – “More Bathroom Trips”
Dieters commenting online are stating Activia ingredients cause side effects. “I’m now in the middle of the second 14 day cycle. I have diarrhea almost every day. Out of 14 days, I had 3, maybe 4 days without the runs. And when I say runs, when I get then its ALL day,” reported a user. 
“I had Activia yogurt for breakfast and now, 6 and a half hours later, I think I’m dying. I’ve been doubled over and gassy for the past two hours and now I’m vomiting and have diarrhea,” said a customer.
“I have been eating 2 Activia a day for the past week and feel more bloated and gassy than before I started eating it. I like it but don’t like feeling this way,” offers a consumer.
We’ve done the research and have concluded that something small, like side effects, could cause a reduction in long-term success. If Activia causes negative reactions, dieters won’t bother with it.
The Science – “Legit?”
The official Activia website makes the case that the yogurt is beneficial, but doesn’t provide scientific research linking the formula to weight-loss. We found contradictory information about one of the active ingredients. According to the World Journal of Gastroenterology, “B. M13-4 (bifidus regularis) action may generate a new conception: certain probiotics may promote BW (body weight) gain by more effective fat absorption, and a cautious assessment is needed before probiotics therapy is given.” At DietSpotlight, science is a critical part of the review process. If there’s no proof, we don’t bother with it.
The Bottom Line – Do Activia Ingredients Work?
Should you stop what you’re doing and run out to buy Activia? We like that we located some favorable customer comments and that the company has been in business for years. But, we have reservations because of the lack of published scientific research linking it to weight-loss. We’re also concerned about the excessive sweetness and reported potential side effects.
Dieters wanting to lose those extra pounds may try going with a supplement with ingredients supported by published scientific research and no reported side effects.
Among the best products we’ve seen in this year is one called Dietspotlight Burn. The supplement contains a formula consisting of a proprietary blend of four ingredients, which published clinical research shows to help boost fat loss and jump start metabolism. There’s no one talking about negative side effects and consumer comments on the web focus on people seeing excellent results.
Additionally, the company that makes Dietspotlight Burn, in a good sign of confidence in the supplement, is providing a special trial offer, impressive.
Activia Side Effects:
Dannon’s Activia yogurt is a popular weight loss snack. Most people eat it without issues, but there are many cases of discomforting side effects.
Abdominal pain can range from mild to severely acute.
Stomach pain and cramps are not always serious, but they are cause for alarm if accompanied by symptoms like fever, frequent urination, difficulty breathing, and vomiting blood.
What causes stomach pain?
Stomach pain can be caused by many different conditions—which is why it’s so important to see a doctor if your abdominal pain is persistent. Typical causes are indigestion, stomach virus, ulcers, food poisoning, hernias, kidney stones, and appendicitis.
You are constipated when you’re unable to pass stools for abnormal periods of time. Often, bowel movement is accompanied by pain. You are constipated when you have fewer than three bowel movements a week. 
Many people suffering from constipation also report having hard stools. You may find yourself having to press your abdomen in order to fully empty your rectum.
What causes constipation?
Constipation occurs when the stool moves too slowly through your digestive tract. This makes it hard and difficult to remove. This condition is the result of a narrowing of the colon, bowel obstruction, anal fissures, and even colon cancer.
Bloating is when your abdomen fills with air or gas, giving your stomach a swollen appearance and even making it hard to the touch. Discomfort and nausea may occur simultaneously with bloating.
What causes bloating?
Overeating, gas, stress, and indigestion all lead to bloating. When these are the causes, bloating typically goes away within a couple hours.
Bloating can also be a byproduct of more serious ailments like appendicitis, Crohn’s disease, irritable bowel syndrome, and urinary tract infection.
Diarrhea is when your stool is watery. It’s extremely uncomfortable and is usually marked by a need to use the restroom with unusual frequency.
Staying hydrated helps alleviate diarrhea. Drink your liquids between meals rather than with them.
What causes diarrhea?
The flu virus can cause diarrhea, as can allergies. Diarrhea may also occur due to intestinal diseases, overactive thyroid, and malabsorption of certain nutrients. 
Activia is a well-known and highly-marketed product available in most markets. Side effects are rare, but they can produce significant discomfort when they do happen.
If you begin to experience any of the above side effects, pause your consumption of Activia and seek the assistance of a physician before continuing use.
Side effects are not common in those who eat Activia, but some have been noted by customers. These do not stand for the majority, but there is always risk when taking any supplement.
“I tried Activia by Dannon and was not pleased. The first day I had diarrhea. The next 3 days I had constipation. The next 4 days I had to push really hard for very little #2 outcome.” Joe
“I started eating Activia yogurt three weeks ago and have been experiencing extremely painful abdominal pains every night, have spent two days in bed vomiting and also had diarrhea.” Marilee
“I have been on Activia for a week, and so far the only difference that I have notices is a burning sensation in my upper digestive tract and a lot of gas and belching which has kind of subsided now and just soreness in my upper stomach.” Karla
“I had Activia yogurt and I am suffering from terrible cramps, bloating, and gas.” Gloria
“Started Activia yogurt about a week ago and woke up this morning with a major urgency to use the bathroom. It’s been 1 hour and I have been in there 4 times. My stomach is cramping badly and it feels like I am gonna vomit.” Michelle
“I started Activia yogurt on 5/18 after two weeks of eating 1 yogurt per day, I started having really bad smelly gas.” Kim
“I started Sunday and by Tuesday I’m having abdominal cramping and almost flu like systems.” Nina
“I ate Activia yogurt on Friday and now its Monday………I’m still going to the bathroom way too often………diarrhea…….stomach pains.” James
“Have been taking 1 Activia yogurt per day, man I don’t know how this is, but I am going to the washroom more than normal, watery stool.” Nicole
“I ate Activia yogurt one day and the following day I had to make several cramp filled, cold sweat accompanied trips to the bathroom with mild diarrhea.” Ann
“I’ve always had a healthy and regular digestive system and after a couple days eating Activia once a day I had to stop due to frequent diarrhea I experienced.” Kasey
“I had been eating Activia yogurt for a couple weeks off and on, not daily but kept getting loose stools and stomach cramps.” Monique
We are all for reducing the risk of side effects when using any weight-loss supplement. We have noticed that Activia reviews are great with very few grievances.
We’ve taken a deep look at Activia, but with reports floating around of Activia side effects, we’ve chosen to dig a little deeper. (You can feel free to check out our full Activia review.) The ingredients and any clinical testing was an important part of this process. We also chose to pore through hundreds of customer experiences to see how this yogurt affected real people. With all these facts in hand, we give you the bottom line.
What You Need to Know
First off, Activia is a yogurt that contains non-fat milk, water, food starch, inulin and various probiotics. You are supposed to eat it once daily to promote healthy bowel function. This could have a positive effect on weight-loss as the stomach and intestines play a part in nutrient and supplement absorption. The product is perishable, so you’ll need an ice pack to take this one with you.
The product, offered up by Dannon, does not make extraordinary claims, a good thing. Purchases can be made through local grocery stores and via some online outlets. We like that yogurt is a low-calorie, healthy option for some dieters, but read on…
Our first concern with Activia side effects is diarrhea. “With this yogurt you want to restore your intestinal system to the best shape it can be,” says our Research Editor. “You don’t want to spend hours on the toilet.”
“I started the Activia 14 day test. I’m now in the middle of the second 14 day cycle. I have diarrhea almost every day. Out of 14 days, I had 3, maybe 4 days without the runs,” a consumer shares.
“I tried Activia, one day at work during a graveyard shift at the prison. 30 minutes go by stomach begins to cramp and then the diarrhea for 2 hours,” says another.
The effect was a drastic change for some, “I have been having diarrhea since I tried Activia. This isn’t for me. I have longed suffered from constipation but this seems to have just the opposite effect. Not good!!!!!”
There are also numerous reports of gas and bloating.”TERRIBLE!! I’m bloated! I have gas! & yesterday I nearly died trying to pass my BM! Not trying to disgust anyone but it was very large & rock hard! This yogurt should be banned!,” says a customer.
“I have been using Activia for 8 days and the cramps and bloating are becoming quite unformortable,” offers a consumer.
Another said, “Activa did a number on me with intense gas, bloating and farting!”
Based on our research, it can take something tiny, like gas, to offset your chances of long-term success. If Activia side effects are an issue, the dieter won’t stick around for long.
We didn’t find any clinical evidence on the official website proving a connection between Activia and losing more. We found nothing to support it either, but we did find a clinical report that the active ingredient in the yogurt was ineffective. According to Nutrition Research, “probiotics have limited efficacy in terms of decreasing body weight and BMI and were not effective for weight loss.” At DietSpotlight we can’t give a thumb up to any product that doesn’t have science on its side. If this one is not in the beneficial category, why spend the money?
The Bottom Line
We enjoyed looking more closely at Activia side effects and our research left us confident about our take. We like the natural ingredients and the trust consumers have in Dannon as a company, but we can’t suggest a product that is clinically proven to have no positive impact on weight-loss. It also concerns us a bit that dieters report gas, bloating and diarrhea after consuming the yogurt.
If you got that weight-loss bug, we suggest trying out a supplement with scientific proof it can help you to take down the scale. It’s also great if there are no reported side effects.
Among the best products we’ve reviewed this year is one called Dietspotlight Burn. We found a formula of four ingredients packaged in a proprietary blend that has been clinically tested and proven to help support metabolism and spark fat loss. Side effects are not part of the equation, based on our deep look into dieter reviews. We did find numerous people telling the world online about seeing great results.
Also, it’s a good sign that the makers of Dietspotlight Burn are so confident in the formula that they’re offering a special trial offer.

Previous Activia Review (Updated July 9, 2014):
Activia - What You Should Know
Activia is a low-fat yogurt made by Dannon infused with Bifidus Regularis, an active probiotic culture that is claimed to reduce "intestinal transit time" by regulating the digestive tract. Dannon says it may help women clear up digestive issues in combination with a healthy diet, and may clear up issues that make the digestion process slower. They claim this effect can be experienced in roughly two weeks, allowing for optimum digestion and fewer cramps. Activia is available worldwide, including grocery and specialty stores.
Activia is currently the only yogurt on the market claiming to have probiotic cultures in their product, and Dannon publicly states this is an optimum way to regulate the digestion system. They even say they have scientific evidence that backs up these claims, stated on their official website. Activia may not contain the benefits claimed by Dannon, however, and their so-called studies appear to be the result of original research.
Activia only states its yogurt contains milk-derived ingredients, sugar, and Bifidus Regularis. We went into great depth researching the Activia Ingredients
Product Features of Activia
Activia emphasizes that its probiotic cultures promote proper digestion and may help supplement a healthy diet. Further examination reveals that their scientifically-backed facts aren't legitimate studies at all -- these studies were conducted by their own company and are not confirmed by any third-party sources. There has not been studies confirming the benefits of probiotic cultures, and researchers emphasize that more studies are needed to even confirm any benefits. They do not believe it is dangerous, however. Any benefits stated by Dannon simply have not been proven by third-party studies, putting their claims into question. Consumers also question the legitimacy of their claims, stating they did not experience better digestion. Some consumers have also complained of increased stomach irregularity, including diarrhea and cramps. Activia is rich with vitamins and minerals, however, but their probiotic cultures may be used in an unsafe manner.
- Is an affordable and widely available yogurt.
- Can be purchased in most grocery stores in the United States.
- Contains nutrients and minerals which may help aid a healthy, nutritionally sound diet.
- Bifidus Regularis is not proven to help aid digestion, and further studies are recommended to confirm if it does have any benefits.
- Consumers state it actually causes intestinal discomfort and diarrhea. (See reader comments.)
- Possible Activia Side Effects may deter dieters.
- Not ideal for diabetics contains excessive sugar.
Activia - Our Conclusion
Activia is touted as a digestion healing yogurt ideal for female intestinal issues, but evidence simply does not back this up. There are also reported side effects not listed on Activia's website. Nevertheless, it does contain some nutrients which may supplement a healthy diet, but consumers should be aware of the heavy sugar content and some unnatural ingredients added to their yogurt.
Activia Scientific Abstracts:
Data collected from major cross-section studies show a beneficial link between higher intake of sugar-sweetened beverages and weight gain as well as obesity in adults and children. Short-term feeding trials resulted in support of sugar-sweetened soda consumption and the induction of positive energy balance. However, there are very few of these reports. One school-based intervention study discovered substantially less sugar-based drink consumption and widespread obesity of children in the intervention group than in the control participants following a 12 month period. The amount of experimental and epidemiologic evidence linking higher intakes of sugar-sweetened beverages to weight gain and obesity is significant. More research is required; however, there is more than enough current evidence to discourage sugary beverage consumption as a part of a healthy lifestyle. 
Beverages and foods are sweetened using fructose because it’s inexpensive and contains useful properties for the manufacturing process. Fructose in high fructose corn syrup and sugar lends a sweet quality to drinks, which may ultimately be the reason for soft drink intake obesity. Ingesting fructose has also been linked to metabolic syndrome as well as abnormal lipid patterns. This data indicates that there should be concern about some fructose humans consume, which has been gradually elevating for 200+ years and has been the main source of energy (by over 10%) for some individuals. 
When sugar-sweetened beverages were consumed, total energy intakes were elevated to 7.8% (ΔTEI range −7.5 to 18.9). There is a consistency in the studies that have compared nonnutritive sweeteners with water, finding no effects on energy intake within adults (ΔTEI = −1.3, range −9 to13.8). Some studies provide much less certain data when replacing water with juice and milk, seeing raises in total energy intake at test meals of 14.9% (range 10.9 to 23.9). The conclusion from these findings suggests a potentially critical role for water in the decreasing of energy intake, thus an important part in preventing obesity. There is a need for randomized controlled trials. 
81% of the subjects finished the trial (85% calcium + D group; 78% control group). There was a substantially greater reduction in fat mass loss noticed in the calcium +D group (−2.8±1.3 versus-1.8±1.3 kg; P=0.02) in comparison to control, but no substantial alterations were noticed in body weight change (P>0.05) in either group. Calcium + D participants showed greater reductions in visceral fat mass as well as visceral fat area (P<0.05). Metabolic variables remained unchanged (P>0.05). In conclusion, calcium + vitamin D3 supplement consumption for a 12 week period altered body fat and visceral fat loss within extremely low calcium intake subjects during energy restriction.
