What is PhenAprin?

The PhenAprin label proclaims it is an oral metabolic activator for burning fat, stimulating users, and combating weight. Can this formula produce some of those claimed results?

  • Nutrients: The manufacturer claims its PhenAprin ingredients act as an appetite suppressant. A study published in 2020 looked into the effects of L-Phenylalanine on energy intake and glycemia. The data supports the idea of appetite suppressant effects using this ingredient. Energy intake suppression likely involved various gut hormones in the male participants.
  • European Journal of Sports Science: PhenAprin diet pills contain Caffeine Anhydrous as part of its proprietary blend, which is supposed to offer an energy boost. Results of a 2017 randomized, double-blind, cross-over study examined caffeine ingestion in resistance-trained men. It concluded that participants experienced benefits likely associated with decreased RPE (rate of perceived exertion).
  • Biotechnology and Bioprocess Engineering: One of SutraHealth’s claims about PhenAprin is the ability to burn excess body fat. The proprietary blend contains Theobromine, an ingredient discussed in a 2018 article. It states that Theobromine consumption could activate thermogenesis and improve systematic lipid metabolic functions, protecting against obesity and metabolic disorders.

PhenAprin Claims

SutraHealth claims that PhenAprin diet pills are a cutting-edge nutraceutical that increases energy, curbs hunger, and combats obesity. PhenAprin ingredients purportedly stimulate thermogenesis and regulate metabolism while reducing appetite during active digestion.


PhenAprin Ingredients

One serving of PhenAprin diet pills equals a single tablet. The main PhenAprin ingredients come in a 540 mg proprietary blend containing:

  • L-Phenylalanine
  • Caffeine Anhydrous
  • Theobromine
  • L-Taurine
  • L-Carnitine (as L-Carnitine Tartrate)
  • DHEA (Dehydroepiandrosterone)

Other ingredients include Dicalcium Phosphate, Microcrystalline Cellulose, Stearic Acid, Sugar, Croscarmellose Sodium, Magnesium Stearate, Corn Starch, Silicone Dioxide, and FD&C Blue #1.

Weight Loss

Does PhenAprin Work for Weight Loss?

SutraHealth’s cutting-edge nutraceutical includes L-Phenylalanine. The Journal of the International Society of Sports Nutrition published results from a double-blind, placebo-controlled crossover trial in 2017. It looked into the effect of Phenylalanine on exercise-induced fat oxidation. Results suggested that pre-workout supplementation of the ingredient could stimulate whole body fat oxidation.

A 2020 review article in Nutrition Research looked at caffeine’s effect on systematic metabolism. The article summarized relevant literature regarding caffeine use in various metabolic situations, noting beneficial influences on oxidative status and anaerobic or aerobic physical exercise. PhenAprin contains Caffeine Anhydrous in the proprietary blend that might produce these positive effects.

A rodent study published in 2020 looked at Theobromine’s effect on diet-induced obesity in mice. The European Journal of Nutrition concluded Theobromine alleviated diet-induced obesity in mice by browning inguinal white adipose tissue and activation of brown adipose tissue. SutraHealth’s cutting-edge appetite suppressant contains Theobromine in its 540 mg blend.

Not all of PhenAprin’s ingredients will curb appetite or boost metabolic function. L-Taurine offers other potential benefits to dieters. The European Journal of Pharmacology looked into how Taurine affects obesity, blood pressure, and lipid profiles in 2020. Its meta-analysis highlights the ingredient’s positive influence on health markers like blood pressure, total cholesterol, and triglycerides.

That said, L-Taurine might help improve the effects of a weight loss diet. Amino Acids published the results of a study in 2020. Those findings demonstrated that taurine supplementation added to a weight loss diet improved the resulting lipid profile and metabolism in obese female subjects compared to those using diet alone.

The blend used to curb appetite in PhenAprin uses L-Carnitine. A meta-analysis article in Clinical Nutrition ESPEN examined the ingredient’s effect on weight loss and body composition in 2020. It highlights that L-Carnitine might influence body weight and makeup in adults. Discussions include evidence of significant reductions in body weight, BMI, and fat mass.

Finally, the publication Steroids looked into the effect of the ingredient DHEA (Dehydroepiandrosterone) on body composition and blood pressure. The 2020 article noted that DHEA did not alter diastolic or systolic blood pressure, body weight, or BMI. However, it states that DHEA supplementation increases lean body mass and reduces fat mass.

Side Effects

Potential PhenAprin Side Effects

All dietary supplements, including PhenAprin, can create an unwanted reaction when taken. These products can cause allergic reactions or interact negatively with other drugs. Potential PhenAprin side effects could include excess energy, jitters or shakes, difficulty sleeping, irritation, and stomach upset from the caffeine intake. 

PhenAprin vs. Phentermine

Is PhenAprin the same as Phentermine?

No. Phentermine is a prescription medication sold under the brand name Adipex-P or Lomaira. Its active ingredient is Phentermine hydrochloride. The prescription medication is given short-term to those with obesity or who are overweight with health-related complications.

PhenAprin is a nutraceutical (a pharmaceutical alternative available without prescription that is unregulated by agencies like the FDA). The first listed ingredient in the proprietary blend is L-Phenylalanine.

Some PhenAprin reviews mention similar Phentermine and PhenAprin side effects, but they act on the body differently.

Can I Take With...

Can I Take PhenAprin With…

Dietary supplements (like PhenAprin) and the companies that make them (like SutraHealth) are not approved or regulated by the Food and Drug Administration.
