Buying Guide

Dose per serving

Check milligrams per capsule or serving — options here range from 500 mg to 600 mg, so match dose to your target intake and any practitioner recommendation

Capsule count and serving format

Consider total capsules per bottle (single and multi-bottle options exist) to estimate monthly cost and dosing convenience for daily use

Dietary preferences and allergens

If you need vegan, gluten-free, or non-GMO formulations, look for brands that explicitly list vegan capsules or gluten-free certifications

Brand transparency and positioning

Prefer brands that list ingredient purity and identify L-lysine as an essential amino acid for immune-support or skin-health contexts

Price vs. serving value

Compare price per capsule or per 1000 mg of L-lysine to evaluate budget options versus larger-count bottles for better per-serving value
