Weight Loss Ingredients

Losing weight requires a lot of hard work. It takes an enormous amount of willpower to exercise every day, count calories, and carefully measure food servings. Still, with obesity on the rise in America, most folks don’t have a choice because every extra pound of fat that a person carries contributes to their risks of developing a serious health condition from it, such as heart disease or diabetes.

So to make the process a little easier, many people turn to weight loss supplements that promise to deliver fast results with little to no side effects. But before ever taking them, it is crucial that consumers read the labels of the supplement bottles very carefully since not all weight loss active ingredients are safe.

Want to know more about the weight loss herbal ingredients that are found in weight-loss supplements and how they could affect your body? Then, read on for a list of the answers to the most commonly asked questions.

What are Weight Loss Ingredients?

Weight loss ingredients are either natural or synthetic herbs, compounds or extracts found in supplements. Usually found over-the-counter, there are some weight loss ingredients included in prescription weight loss pills.  [1]

How Do Weight Loss Ingredients Work?

Some weight loss ingredients are supposed to work by increasing the body’s metabolism and fat-burning ability. But some also claim to be able to prevent the absorption of carbohydrates and fats from foods, so they never have a chance to accumulate in the body as extra weight. [2]

Weight Loss Ingredients and Weight Loss

There are several systems of the body that are affected by weight loss drink ingredients. The first one is the endocrine system.

Most weight loss ingredients supplements claim that the reason that a person is struggling to lose weight is that they have a slow thyroid, which is part of the endocrine system.

So they add in weight loss ingredients that work to speed up the production of thyroid hormones in the body, especially the thyroid hormone T3 because of its influence on the metabolism. Two ingredients that affect the thyroid are iodine and kelp.

The digestive system is affected by weight loss ayurvedic ingredients too. This is mainly because the weight loss ayurvedic ingredients block the absorption of fats and carbohydrates. So instead of reaching the bloodstream, they are flushed out with the rest of the body’s waste that is produced.

The last system of the body that is affected by weight loss pill ingredients is the cardiovascular system. If banned weight loss ingredients are used instead of the best natural weight loss ingredients, then a person can develop damage to their heart and arteries.

While the FDA has worked hard to keep the banned weight loss ingredients off the market, many people still attempt to purchase them through internet-based companies who care more about profit than the health of their customers.

One example of a banned weight loss ingredient is ephedra. It has been known to cause heart attacks and strokes because of its effect on a person’s blood pressure and heart rate.

Ephedra is also quite addicting. Some studies have shown that it affects the body in a similar way to illegal amphetamine drugs.

Still, since this banned ingredient seemed to be so effective at boosting energy and weight loss, some weight-loss supplement manufacturers use other natural weight loss drinks ingredients that have a similar effect on the body.

And they post this information on the packaging for consumers to see. This is misleading because a person may think that they are purchasing the actual ephedra when the supplements only contain a substitute for it. [3]

The Best Weight Loss Ingredients

The following is a list of some of the best natural weight loss ingredients that weight-loss supplements that are currently on the market commonly contain:

White Kidney Bean Extract

White kidney bean extract is useful for blocking the absorption of carbohydrates, so they don’t get turned into fat. [4]

Diabetics often find it especially helpful because it is commonly sold as the sole ingredient in several easy-to-find supplements.


Chitosan is a by-product of the shells that come off of seafood animals once they are processed for consumption. It works by reducing the body’s ability to absorb fat from food that is eaten.

One of the best things about weight loss ingredients that work, such as chitosan, is that their effects take place immediately. This is different than those supplements that take several weeks for someone to see any results from them.


There’s little mention of concern when taking some weight loss natural ingredients; such as cinnamon. The main reason that this flavorful spice gets added to a weight-loss supplement is that it helps control blood sugar so well.

And when a person’s blood sugar is under control, they often don’t have the same amount of cravings for sweets and carbohydrates that they normally would.

Flax Seeds

Ground up flax seeds are another form of natural blood sugar stabilizers that are mixed with other weight loss natural ingredients.

They are high in fiber, so the seeds help slow down the absorption of sugar and carbohydrates. And they can help a person feel fuller for longer, which reduces the temptation to snack on unhealthy treats.

Whey Protein

Whey protein is one of the best weight loss ingredients that is found in weight-loss juices that are sold because it keeps a person feeling full for several hours. The protein-rich whey comes from the liquid that is left over when companies make cheese, so it is very safe to consume.

Coconut Oil

Many health agencies advise against the overuse of coconut oil because it is very high in trans fats.

However, if it is taken in small amounts, along with other weight loss ingredients, it usually poses no risk of increasing a person’s cholesterol level.

Weight loss ingredients, such as coconut oil, are very important to losing weight because they help flush waste and toxins out of the body, which are impairing the liver’s ability to work at its best.

Green Coffee Bean Extract

The ground-up coffee that people purchase for their favorite morning brew is made with coffee beans that have gone through a fermentation and roasting process which helps improve their flavor.

Unfortunately, the process also destroys some of their best health properties that work well with other ingredients in weight loss pills for weight loss. Because of this, green coffee bean extract is made out of coffee beans that have been left in their fresh, natural form.

Cayenne Pepper

One of the spiciest weight loss ingredients supplements contain is cayenne pepper. It works because of the way that the body’s defense mechanisms react to it.

The heat that it produces signals pain receptors that quickly respond with anti-inflammatory agents to soothe the area. But at the same time, the cayenne is also speeding up the metabolism system, so more calories are being burned.

Bitter Orange Extract

Bitter orange extract is one of the weight loss herbal ingredients used by those who want to take as few weight loss drug ingredients that they can. It can lower high blood sugar levels, so a person doesn’t gain weight from the extra sugar that is in their bloodstream. And it regulates the amount of fat that is released from the food that a person eats.

Weight loss ingredients such as bitter orange extract may increase urination. [5]

How Do You Take Weight-Loss Supplements?

Most weight-loss supplements have to be taken early in the day because they contain some form of stimulant or caffeine in them that could cause a person to have difficulty sleeping at night. However, they don’t all work the same way.

Those supplements with ingredients that help prevent the absorption of fats, sugars, and carbohydrates have to be taken about 30 minutes to an hour before each meal is eaten. This is the most common with white kidney bean extract supplements and chitosan supplements.

But bitter orange extract and other herbal remedies may also need to be taken prior to eating because they have an irritating effect on the gastrointestinal system.

Weight Loss Ingredients Side Effects

Side effects from weight loss ingredients depends on the person, the amount consumed and personal health issues. While not all inclusive, some weight loss ingredients side effects may include:

  • High blood pressure
  • Nervousness
  • Anxiety
  • Insomnia
  • Frequent urination and diarrhea
  • Abdominal pain
  • Rash and itching

Combining Weight Loss Ingredients

It is best to never combine any weight loss drink ingredients with other prescription medications or health supplements without consulting a doctor first because a drug interaction could occur.

Many new weight loss ingredients work by blocking the absorption of fats, sugars, and carbohydrates.

But when then do this, they are also blocking the absorption of the other medications that a person takes.

This can cause dangerous health problems in a person who needs special medications to control their diabetes, blood pressure, or kidney or liver diseases. And on top of this, even the most effective weight loss ingredients that have been mentioned in this article can exacerbate other health conditions that a person has. [6] [7]

Who Should Use Weight Loss Supplements?

Weight-loss supplements should not be used by everyone because of the serious health consequences that they can have on the body. Pregnant or nursing women should never take them since there is a high risk of their baby being harmed by them.

And young children shouldn’t either because their development could be negatively impacted by them since they can sometimes affect the endocrine system, which has an impact on hormone production.

Overweight senior citizens have to be especially careful because they already have a higher risk of heart disease and stroke because of their age. But even younger people who are suffering from high blood pressure might need to avoid them if their doctor feels that they could develop an adverse reaction to them.

Only adults who have no history of kidney, liver, or heart disease may be able to use weight-loss supplements safely. They still have to check with their doctor first to make sure that all of the ingredients that are in the weight-loss supplements are right for them. [8]

The Bottom Line on Weight Loss Ingredients

Overall, most weight loss supplements that are sold over-the-counter are safe for adults with no other health conditions who are not pregnant or nursing to take. But they each have a unique set of ingredients, which can all have different effects on the body.

The main problem with weight-loss supplements is that many of them make false claims about their efficacy, so people think that they are going to lose an enormous amount of weight in a short period of time. This causes them to not change their eating and exercise habits because they assume that the supplements are going to do all the work for them.

There are also issues with the studies that are done on the ingredients that are in weight-loss supplements. Many of them are independently sponsored by the companies who intend to sell products with them. Since the companies want to have a high sales volume of their products, they often fail to reveal accurate test results.

Consumers can avoid falling into scams like this by looking online to see if there has been any outside research done on the ingredient’s efficacy by respected educational sources, such as those commonly done by Harvard or other medical schools. If there isn’t any, it is probably because the ingredient isn’t one that is considered to be of any true value by the medical field.

And lastly, it is important to mention that even the most effective weight-loss supplements only cause a modest weight loss of one or two pounds per week when they are taken according to the directions. So those who are struggling to find one that will work for them can often get the same results by eating a healthy diet and exercising regularly. [9]
