Product analysis
L-Lysine 500 mg offers an economical way to add an amino acid used in protein nutrition. Any hair benefit remains uncertain because the relevant evidence concerns combinations used by people with low iron stores.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality40
The lysine form is identified, but its relative quality cannot be judged confidently. Naming the form alone does not establish a special absorption advantage.
Ingredient Transparency100
The lysine amount and form are both stated. That clarity makes the supplement easy to compare with other single-ingredient options.
Value For Money100
The lysine offers favorable value for the amount supplied. The price information is older, so the current comparison is less certain.
Customer Satisfaction90
Customer feedback is strongly positive across thousands of ratings. The sizeable response base gives a broad picture of satisfaction without establishing hair benefits.
Product Focus71
The simple formula supplies lysine without additional active ingredients. Hair-related findings concern particular combinations and low iron stores, so an independent hair-growth benefit is uncertain.

Goals
Lysine is an amino acid relevant to protein adequacy. The supplied support concerns selected combination regimens in people with low ferritin, which does not establish an independent routine hair benefit. The 500 mg per serving partly matches the supplied amount reference without establishing a proven hair-growth dose.
