Analysis

The formula provides 1,500 mg L-lysine with vitamin D3 in a focused daily serving. That lysine amount offers better dose efficiency than the chewable version and avoids added gummy-style carbohydrates.

The 25 mg immune blend is not broken down into ingredients or individual amounts. Its small size makes it unlikely to be the main reason to choose the product, and the chloride amount largely reflects the amino-acid salt or formulation.

Three capsules per serving provide a useful lysine amount at fair value. It suits users seeking targeted lysine who do not need a broader amino-acid blend.

Who is it for
  • Adults seeking a substantial lysine dose
  • Users who prefer capsules over chewables
  • People wanting added vitamin D3
Best for
  • Focused lysine supplementation
  • Higher-dose amino-acid intake
  • Simple daily use

Vitamin D · 10 mcgLysine · 1500 mg

A well-dosed L-lysine serving provides an amino-acid building block relevant to keratin and may support iron utilization. Vitamin D adds basic follicle nutrition, but no iron, zinc, biotin, silicon, or hormonal active is included.

The lysine amount falls within a useful targeted range and is fully disclosed. Its exact chemical form is not stated, and the small immune blend adds little to hair support.

C Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyB+ Value

The isolated lysine amount is visible, but its chemical form is not fully specified. The amount fits the preferred range, though serving convenience varies with the format. Cost efficiency is favorable, while full additive disclosure remains unavailable.

Chloride · 356 mg OverallScore63
F Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB+ Value

The specific chloride source salt is not disclosed, and the 356 mg amount provides a meaningful electrolyte amount. The capsule uses conventional delivery, while the label states the dose without naming a specific salt. Cost efficiency is good for the chloride delivered.
