Isopure Protein Ingredients
Let’s look at some of the more prominent ingredients in Nature’s Best Isopure protein products. These ingredients include:
- Whey protein isolate
- L-glutamine
- Caffeine
- L-theanine
- Isoleucine
Whey Protein Isolate
Whey protein isolate is a dietary ingredient made by separating milk components. Whey can be processed to create three different types of protein:
- Isolate
- Concentrate
- Hydrolysate
L-Glutamine
L-Glutamine is a non-essential amino acid that is made by the body but also found in some foods. The human body requires 20 non-essential and essential amino acids to make a variety of different proteins.
L-Glutamine is most often used for:
- Treating weight and intestinal issues
- Soreness and swelling in the mouth (caused by chemotherapy)
Caffeine
Caffeine is a stimulant most commonly found in coffee. It is a bitter, psychoactive substance found in the seeds, leaves, and nuts of many plants native to South America and East Asia.
Some of these include:
- Coffee beans
- Kola nuts
- Tea leaves
- Cocoa pods
Although caffeine is widely consumed and said to be safe, it can come along with its fair share of side effects.
L-Theanine
L-Theanine is an amino acid analog of L-glutamine. It’s found in plant and fungal species and is considered a constituent of tea.
Isoleucine
According to Biochemical and Biophysical Research Communications, this ingredient is an amino acid used in proteins’ biosynthesis. It’s one of the three branched-chain amino acids (along with leucine and valine), which promotes glucose uptake and consumption.
Isoleucine is said to induce muscle protein synthesis and helps promote muscle recovery following exercise. Isoleucine is broken down for energy within the muscle tissue.
Does Isopure Protein Work?
The best way to determine whether a product works or not is to look at the scientific research and customer reviews. There’s no doubt that the ingredients in these products work to some extent. Each one comes along with its bevy of research, with whey protein leading the pack.
Our team combed through customer reviews and found users are happy as well. Most reviews are positive, touching on effectiveness as well as the flavor of Isopure protein products. Some customers weren’t happy with the taste of Isopure, and most negative reviews centered around the quality of the products.
Isopure Protein Benefits and Results
Nature’s Best Isopure Protein claims to come along with a list of benefits:
- Muscle recovery
- Weight management
- Appetite control
- Energy
For this section, however, we focus on the science behind some of the main ingredients.
Whey Protein Isolate
Whey protein contains a range of amino acids that are absorbed quickly. Studies have shown that it can help with fat loss, muscle gain, and increased strength.
Whey protein is popular with bodybuilders because of its ability to increase muscle size and strength. It increased the release of anabolic hormones, which is said to stimulate muscle growth.
According to Nutrients, whey protein is also said to help control appetite and have weight-loss benefits.
One study by the Journal of Obesity and Metabolic Syndrome weighed the effects of high protein intake on appetite and satiety in overweight men. It concluded, “many clinical trials have shown that consuming more protein than the recommended dietary allowance induces weight loss and improves body composition regardless of total energy intake.
L-Glutamine
L-glutamine is an amino acid that plays quite a few roles in the body. They act as building blocks for protein and can fight off harmful viruses and bacteria.
Glutamine can be found in foods such as:
- Eggs
- Skim milk
- Corn
- White rice
- Beef
- Tofu
According to the Journal of the International Society of Sports Nutrition, L-glutamine is beneficial to the immune system, improves intestinal health, and promotes muscle gain and performance.
Caffeine
Caffeine is the most commonly used stimulant in the world. Although high amounts of caffeine can be harmful to your health, there are some compelling health benefits if used correctly. In over-the-counter medicine, caffeine is used to treat drowsiness, tiredness, and enhance pain medications’ effects.
L-Theanine
L-theanine is known for a small handful of benefits. Some are:
- Stress relief
- Improved immunity
- Increased focus
- Improved sleep quality
According to the Journal of Neuroscience, “the combination of moderate levels of L-theanine and caffeine significantly improved accuracy during task switching and self-reported alertness.”
Isopure Protein and Weight Loss
These products are promoted mainly as muscle builders and performance enhancers, but there are some claims of weight loss, which we needed to investigate. Our research team did find some evidence of weight loss surrounding whey protein isolate and caffeine.
Caffeine and Weight Loss
Caffeine “communicates” directly with fat cells, helping to break them down. Caffeine is said to help stimulate the sympathetic nervous system and increase lipolysis. Caffeine may also help increase the metabolic rate and helps burn fat.
According to the American Journal of Clinical Nutrition, “an increase in dietary protein from 15% to 30% of energy at a constant carbohydrate intake produces…significant weight loss.”
The Nutrients concluded appetite suppression and fat oxidation “were higher on a high-protein diet.” Studies show that replacing calorie sources with whey protein could result in up to 8 pounds of weight loss while still increasing muscle mass.

- Isopure Zero Carb Directions – Mix 1 scoop with 6 fluid ounces of water, milk, or beverage of your choice.
