Analysis

This product provides a broad spectrum of aminos, including lysine and leucine, but the doses are quite low. It is better viewed as a 'multi-amino' for people who may have low protein in their diet. It also includes 300mg of calcium from common sources.

Because the aminos are in milligram amounts rather than grams, it won't replace a protein shake or a high-dose BCAA powder. However, for the price, it is an easy way to add a baseline of nutrients to your daily routine. The tablets are small and easy to incorporate with other vitamins.

Pros

  • Very low cost per serving
  • Contains a wide variety of aminos
  • Includes a small amount of calcium
  • Easy-to-take tablet form

Cons

  • Very low dosages of active ingredients
  • Not effective for muscle building or recovery
  • Uses cheaper forms of some nutrients

Warnings

  • Not a replacement for dietary protein

B- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyA+ Value
This supplement provides isoleucine in a free-form state but at a dosage significantly lower than clinical thresholds. While extremely affordable, it lacks the third-party sport certifications required by competitive athletes.
C+ Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyF Value
This tablet provides a very low dose of histidine as part of a general amino acid supplement. It is not an effective choice for those seeking the physiological benefits associated with standard histidine dosages.
B+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value
This daily amino acid tablet includes a minimal amount of lysine that is insufficient for targeted therapeutic use. It is a general multi-nutrient supplement rather than a concentrated lysine source.
