Analysis

Lysine and arginine pyroglutamate are each supplied at 900 mg, with ornithine adding another meaningful amino-acid amount. Those ingredients fit an exercise-oriented nighttime formula more directly than a focused hair supplement.

Vitamin C and lysine have some relevance to normal collagen support, but carnitine is present at only 10 mg. Chromium and 15 mg of B6 broaden the label without giving the formula a clear hair-specific nutrient foundation.

Four tablets per serving create a substantial pill burden even though the larger bottle supplies many servings. Someone buying specifically for hair would get more direct coverage from a formula that includes zinc, biotin, iron when appropriate, or structural nutrients in meaningful amounts.

Who is it for
  • Adults seeking a nighttime amino-acid combination
  • People interested in lysine, ornithine, and arginine pyroglutamate together
Best for
  • Broad nighttime amino-acid supplementation
  • Meaningful lysine intake

Pros

  • Provides 900 mg of lysine
  • Includes substantial arginine pyroglutamate and ornithine
  • Clearly discloses individual amino-acid amounts

Cons

  • Poorly targeted to hair support
  • Requires four tablets per serving
  • Carnitine and several supporting nutrients are lightly dosed

Warnings

  • Arginine may add to the effects of nitrates or blood-pressure medicines and cause dizziness or excessive blood-pressure lowering
  • Long-term use alongside other B6 products may raise the risk of tingling or other nerve symptoms

Nutrient quality

63 Moderate impact

The major amino acids use specific salt forms that are easy to identify. Arginine pyroglutamate and lysine are substantial, while carnitine is negligible.

Ingredient transparency

82 Highest impact

All listed active ingredients have specific amounts. Inactive tablet ingredients are not supplied.

Customer satisfaction

67 High impact

The supplied average and volume indicate generally favorable aggregate satisfaction. No detailed experience reports are available to identify repeated complaints or confirm perceived benefits.

Value for money

62 Moderate impact

Meaningful amino acid amounts support some value, but the goal fit is weak. The serving cost appears moderate for the disclosed amino quantities.

Lysine · 900 mgVitamin C · 35 mg

L-lysine may support collagen formation and iron use, making it conditionally relevant to shedding. Evidence is most useful when protein or iron status is inadequate.

Lysine approaches a meaningful amount and vitamin C provides modest support. Arginine, ornithine, and carnitine are aimed more at performance than hair.

Report overview
Lysine (L-Lysine Hydrochloride) · 900 mg OverallScore74
B- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyC Value

The 900 mg L-lysine hydrochloride dose is well aligned with targeted supplementation and uses a standard form. Four tablets make the serving less convenient, and the label gives no specific purity or sourcing assurance. Added arginine matches the lysine dose and may undermine lysine-focused uses, though the cost per active amount is moderate.

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 only average for pyridoxine hydrochloride.
