About this product

The serving provides 15 mg of pyridoxine and 45 mg of vitamin C. A three-gram proprietary blend appears to contain the formula's main amino-acid content, but individual amounts are not shown.

Pyridoxine requires conversion to active P-5-P and no riboflavin cofactor is listed. The hidden blend prevents assessment of amino-acid balance, usefulness, and interaction concerns.

Three tablets and premium serving cost make it unattractive for B6 alone. People wanting amino acids should choose a formula that discloses each amino acid and its dose.

Who is it for
  • Adults considering a broad amino-acid tablet
  • Users willing to accept a proprietary blend
  • People not focused on B6 value
Best for
  • General amino-acid supplementation
  • Supporting B6 within a larger formula
  • People who prefer tablets

Pros

  • Moderate B6 amount
  • Adds vitamin C
  • Clearly states the total blend weight

Cons

  • Proprietary blend hides all amino-acid amounts
  • Three-tablet serving
  • Weak value for B6

Warnings

  • The undisclosed amino-acid blend prevents reliable medication-interaction screening
  • People with dietary amino-acid restrictions cannot assess suitability
  • Count the 15 mg B6 amount when stacking supplements

Product analysis

48 out of 100
A costly amino-acid product with modest B6 and poor blend transparency.

AI assessment of the formula, label and price. How scoring works

Nutrient quality58

Vitamin B6 and vitamin C provide modest support for an amino-acid formula. The proprietary blend hides the main ingredient doses and may be filler-heavy.

.
Ingredient transparency34

Named actives have amounts, but the proprietary amino-acid blend hides all individual doses. Missing inactive ingredients and complete directions create further label gaps.

.
Customer satisfaction69

The supplied aggregate rating is particularly strong. The review count is large enough to provide useful rating confidence.

.
Value for money33

A targeted B6 amount offers some functional value. A high serving cost and opaque main blend make the formula poor value.

Pyridoxine hydrochloride is a precursor form, and no riboflavin cofactor is listed to support conversion. The 15 mg dose sits at the lower edge of the preferred range. Price per serving is poor for pyridoxine hydrochloride.
