What is Optimum Nutrition Gold Standard 100% Whey?
Optimum Nutrition Gold Standard 100% is a whey protein supplement containing whey protein, branched-chain amino acids (BCAAs), digestive enzymes, and vitamins. While the product is not recommended for weight-loss by the FDA, many athletes and fitness enthusiasts have used whey protein powders to very effectively lose fat while building muscle. Repeated clinical studies have confirmed this, as stated on the Journal of Sports Science and Medicine.
Gold Standard 100% Whey was introduced by parent company Glanbia as a dietary aide in 1986 and at first glance doesn’t appear to contain artificial ingredients – seemingly a plus. Optimum Nutrition Gold Standard is available to purchase at local health stores and on the official website. We like that we found some favorable customer comments and its affordability, but read on…

Scroll below for one of the best products we’ve seen over the last year.
Optimum Nutrition Gold Standard 100% Whey Ingredients
The first consideration is that Gold Standard 100% Whey is not 100% Whey, as seen on the Supplement Facts label:
While the ingredients list is pretty trim compared to many formulations, there are still a few additional ingredients in Gold Standard 100% Whey that are frequently seen in whey protein powders.
Here is a closer look at the additional ingredients:
Soy Lecithin is added to most protein powders. It is one of the most common food additives used today.
It is worth consideration because soy is a common allergen. While one might not have a severe allergic reaction to small amounts of soy, one could still experience inflammatory side effects such as acne, rash or upset stomach.
Per the Food and Drug Administration (FDA), Soy Lecithin is maybe not as safe as most manufacturers would have you believe.
On April 28, 2016, the FDA issued a recall of several products made by World’s Choice Products, Inc., as these products contained undisclosed amounts of whey protein.
While Gold Standard 100% Whey clearly describes the product as containing soy, many consumers remain undereducated about food allergies and the potential negative effects of soy.
Some of the most commonly-reported side effects of soy allergy include diarrhea, nausea, abdominal pain or fullness. As with most food allergens, side effects vary greatly from person to person, depending on individual tolerance.
One study by theDevelopmental Psychobiology, focused on the effect of soy lecithin administration on motor development in rats. The findings were concerning:
The most marked early sensorimotor deficits were seen in the 5% soy lecithin preparation group, although all soy lecithin preparation-exposed offspring had elevated brain/body weight ratios and choline acetyltransferase levels. Later, animals exposed to lifelong 5 or 2% soy lecithin preparations were hypoactive and had poor postural reflexes. The results indicate that dietary soy lecithin preparation enrichment during development leads to behavioral and neurochemical abnormalities in the exposed offspring.
In short, soy lecithin affected neuromotor development in young rats.
Another study by the Pediatric Clinics of North America specifically examined soy lecithin and milk, the two principal allergens in most whey protein powders. The study found that milk adversely affected 2-3% percent of the studied population, while soy negatively affected 1-2% of the studied population. The study was especially concerned about soy to have negative effects on developing children.
But all of the research on soy lecithin isn’t negative. There is a substantial body of research that connects soy lecithin with improved blood lipid profile and cholesterol markers, which includes the study done by the Cell Biochemistry & Function and another one posted in the journal Cholesterol.
Food allergens affect everyone differently. If a person is not seeing ideal results from a product such as Gold Standard 100% Whey, a hidden ingredient such as soy lecithin could be the culprit. As with all supplements, the best approach is to assess your tolerance carefully and consult with your doctor before adding a potent supplement to your diet or exercise regimen.
This is an artificial sweetener, and like many artificial sweeteners, long-term effects are not usually determined until 5-10 years of consistent use.
One study by PLOS One on Acesulfame Potassium (ACK) found the following:
Interestingly, impaired cognitive memory functions were found in ACK-treated mice, while no differences in motor function levels were detected. Our data suggest that chronic use of ACK could affect cognitive functions, potentially via altering neuro-metabolic functions
AceK increased glucose uptake by 20-30 % at glucose >25 mM, but not in lesser glucose concentrations (<10 mM), nor at 1 min or 10 min incubations. Activation of sweet taste receptors had no effect on glucose uptake in low (<25 mM) glucose concentrations but increased uptake at greater concentrations (>25 mM).
As with most things, moderation appears to be key. ACK had an insignificant effect on glucose uptake in reasonable volumes, but began to affect normal glucose function as the quantity increased.
Bottom Line: Further studies are needed, but Acesulfame Potassium is likely safe in reasonable amounts.
Aminogen and Lactase
These are digestive enzymes intended to help someone break down dietary protein and lactose (milk sugar) respectively. Digestive enzymes are have been taken by bodybuilders, weightlifters, and fitness enthusiasts for many years to assist with performance and physique goals.
The results of this study indicate that supplementing 50 g of WPC (whey protein concentrate) with 50 mg/g or 100 mg/g Aminogen, a blend of food grade proteases from Aspergillus niger and Aspergillus oryzae patented for use as a digestive aid, significantly increased the absorption rate of WPC over controls. these results indicate the need for further research in the area of enzyme supplementation for a more complete digestion of protein and perhaps other processed foods.
Aminogen seems to be a positive addition to any whey protein powder. There are no reported side effects and it has been shown in similar studies to improve the absorption of dietary protein.
However, lactose intolerance remains a problem for many people. According to PubMed Health, people who have difficulty digesting dairy products may only tolerate small amounts of lactose (a sugar found in milk and other dairy products). This is called lactose intolerance.
While Gold Standard 100% Whey only has 1 to 2 grams of sugar per serving, lactose-containing foods remain a digestive nightmare for a lot of people.
The human body naturally produces a digestive enzyme called lactase, but there are many people who do not produce enough lactase naturally to tolerate dairy products well. Exogenous lactase might help a dedicated exerciser reap the benefits of whey protein supplementation without nausea, bloating, or stomach cramps.
Here is the issue: the protein blend in Gold Standard 100% Whey contains both Whey Protein Concentrate and Whey Protein Isolate. While Whey Protein Isolate has had the lactose filtered out, Whey Protein Concentrate has not. And while there are benefits to consuming both types of proteins, lactose-intolerant people might
Gold Standard 100% Whey is, in fact, all whey – it contains no casein protein. But it contains two types of whey, and one of those types contains lactose. This requires Optimum Nutrition to add lactase to improve the digestibility of Gold Standard 100% Whey.
Bottom Line: If you are lactose-intolerant or lactose-sensitive, it is probably better to go with a Whey Protein Isolate rather than a protein blend that contains exogenous lactase.
Optimum Nutrition Gold Standard Side Effects
As noted above, whey protein powder can cause a number of digestive problems, whether due to the milk content or soy lecithin. Aside from some mixed user reviews, there have not been any dedicated scientific studies conducted on Gold Standard 100% Whey.
Lactose Intolerance Side Effects
Pain or cramps in the lower belly.
Gurgling or rumbling sounds in the lower belly.
Loose stools or diarrhea. Sometimes the stools are foamy.
Soy Allergy Side Effects
Tingling in the mouth.
Hives; itching; or itchy, scaly skin (eczema)
Swelling of lips, face, tongue, and throat, or other body parts.
Wheezing, runny nose or breathing difficulty.
Abdominal pain, diarrhea, nausea or vomiting.
Skin redness (flushing)
If you experience any of these effects after using Gold Standard 100% Whey, you should discontinue use immediately.
In 2015, Optimum Nutrition was sued for not filling their containers enough. Apparently, its Whey and Whey Gold products had more than 35% of empty space in each container, according to Class Actions Reporter.
Claimed Optimum Nutrition Gold Standard Benefits
As mentioned above, real-world examples and clinical trials have confirmed the same thing: the combination of whey protein supplementation and resistance training is hard to beat for building muscle while burning fat, according to studies by the Journal of the American College of Nutrition and the Journal of the International Society of Sports Nutrition. If you are looking to improve your body composition and looking to add supplements, a high-quality whey protein powder is a proven place to start.
But the benefits of Optimum Nutrition Gold Standard 100% Whey versus similar products are less established.
Optimum Nutrition does not pretend that Gold Standard 100% Whey is the best product in their protein powder lineup. Even among their whey products, Platinum Hydro Whey – an easily digestible whey hydrolysate – is clearly superior. But it is also more costly. Optimum Nutrition touts Gold Standard 100% Whey as the best value in their whey protein powder lineup, offering less fillers than their Performance Whey product while being less costly than Hydro Whey.
Because the benefits of whey protein supplementation are so well-established, Optimum Nutrition does not go over-the-top with false promises. But while Gold Standard 100% Whey is the top-selling product for Optimum Nutrition, it is not necessarily the top-selling protein powder overall.
Like most protein powders, Gold Standard 100% Whey contains a large dose of BCAAs in every serving. The benefits of ingesting BCAAs in combination with resistance training are also well-established: when consumed in tandem with a broader range of amino acids, those who consume BCAAs build more muscle and have better endurance than those who don’t, according to studies published by the Journal of the International Society of Sports Nutrition.
But this again is a bit of selective advertising by Optimum Nutrition. Most protein powders, especially whey protein powders, have rich amounts of BCAAs, as the BCAAs (leucine, isoleucine, and valine) occur naturally in most protein sources.
Bottom Line: Optimum Nutrition Gold Standard 100% Whey does not claim any benefits that are not backed by extensive research.
Does Optimum Nutrition Gold Standard 100% Whey Work?
How well a protein powder “works” depends on two things:
1) the demand for protein synthesis that a person creates and
2) the amount of protein that is absorbed by the person
If a user has no problems with lactose or soy and performs regular, intense exercise, he or she will likely have very positive results with Gold Standard 100% Whey. However, if a person is sensitive to lactose or soy and does not place the necessary exercise demands on her or his body, she or he will likely have poor results with Gold Standard 100% Whey.
Additionally, some people simply do not respond well to protein powders containing or derived from milk. Thankfully, there are a number of dairy-free, gluten-free, and vegan protein powders available today. Alternate powders to milk-based include pea, rice, and egg, in many more flavors and varieties than were available even 5-10 years ago.

What are the Optimum Nutrition Gold Standard 100% Whey Alternatives?
As established above, within the Optimum Nutrition whey product line, Performance Whey and Platinum Hydro Whey are alternatives to Gold Standard 100% Whey. Hydro Whey is a pure hydrolysate and extremely high-quality, but costly. Performance Whey had added carbohydrates to improve taste and is less costly, but the quality is lower.

Gold Standard 100% Whey can be spoon-stirred, shaken, or blended with the liquid of your choice. Common choices include water, milk, almond milk, and occasionally fast-acting carbohydrate drinks. Optimum Nutrition recommends that you mix one scoop of Gold Standard 100% Whey with 8-10 ounce of liquid. Users generally take 1-3 scoops at one time, depending on their size and physique or performance goals.
Optimum Nutrition Gold Standard 100% Whey and Weight Loss
The new “conventional wisdom” is that higher-protein, lower-carbohydrate diets are optimal for weight loss and body composition. But this has not been proven very consistently in scientific studies.
For example, in one study posted on the Journal of the International Society of Sports Nutritionthe participants were consuming 5.5 times the recommended daily allowance of protein. Bizarrely, this extremely-high protein intake had no effect on body composition in resistance-trained individuals who otherwise maintained the same training regimen. This is the first interventional study to demonstrate that consuming a hypercaloric high protein diet does not result in an increase in body fat.
But the participants in the study above were fed a hypercaloric diet, meaning one in which their calorie intake were higher than their calorie expenditures. Even though dietary protein has a higher Thermic Effect of Feeding (TEF) than carbohydrates or fat, a person still need to burn off more calories than they take in – regardless of the macronutrient ratios.
Based on available evidence, protein appears to be the macronutrient of paramount importance during weight loss owing to its ability to preserve lean mass during weight loss and promote fat mass loss when consumed in higher quantities. In addition, protein has some notable characteristics as a macronutrient, including satiety, thermogenic effect, and a potential ‘leveraging’ effect that means it should be a central part of a plan to restrict dietary energy to promote weight loss.
Dietary protein isn’t a cure-all. Adding a protein powder like Gold Standard 100% Whey will only help if other smart fat-loss strategies are in place.
Bottom Line: higher-protein diets can assist with weight loss, but a caloric deficit is still necessary to lose body fat. Protein has specific importance to athletes, and athletes will likely need to supplement with protein powder in order to meet their personal requirements.

What Users Are Saying
What Users Are Saying
“I was looking for a high-quality and readily-absorbed protein I could take before and after a hard workout. I didn’t want a lot of other stuff mixed in that might add extra calories or make me feel bloated before a workout, so this ON protein pretty much nailed it for my needs. I haven’t tried it with milk yet, but even just with water it tastes pretty good. So for someone looking for a great source of high-quality protein and not much else, this is a great choice.”
“I have no known history of lactose intolerance or sensitivity, but upon trying this for the first time…it literally destroyed my stomach. I had gas, bloating, diarrhea and stomach uneasiness all day after one shake. I kept going for a few days to see if it was just my body adjusting and it got worse. It got pretty bad so I had to switch to something else.”
“This protein powder is OK. I don’t love it but I don’t hate it either. I will probably repurchase this powder (possibly in another flavor) because the ingredients are good and calorie content is good. The price is also good. I just wish this protein was a little thicker when mixed with water and that the waste was a little better. I add peanut butter powder to the mix but I feel like without the peanut butter powder, this would just taste like Hershey cocoa powder mixed with water.”
The Bottom Line on Optimum Nutrition Gold Standard
Alright, can we give this product the go ahead? Well, we like that Optimum Nutrition Gold Standard 100% Whey contains some natural ingredients, and we like the longevity of the company, but we have concerns about it due to the lack of clinical research backing dieters losing weight. Also, we have reservations because of the reported bad taste and the ineffectiveness of the ingredients.
If you want to drop those extra pounds, we suggest going with a program supported by published clinical research and amazing users experiences.
Among the best programs we’ve researched this year is one called Noom. The program consists of a combination of human coaching, personalized meal plans, doctor-designed methods and tips and so much more.
Also, the makers of Noom, in a good sign of confidence in the supplement, are offering a free trial. That’s impressive.
