A highly affordable and effective L-Lysine supplement at a practical 600mg dose, offering excellent value for daily immune and skin support.

Analysis

This L-Lysine product from 21st Century provides a 600mg dose of L-Lysine Hydrochloride per tablet, which is a standard and effective amount for daily supplementation to support immunity, skin, and hair health. Its primary strength lies in its exceptionally low price per serving, making it one of the most affordable options available in the market. The inclusion of 30mg of Calcium Carbonate is a minor addition and doesn't significantly impact its core L-Lysine benefits or absorption. Online reviews generally praise its effectiveness for managing cold sores and overall value, making it a reliable choice for long-term use.

Pros
  • Very low price per serving, offering excellent affordability.
  • Standard and effective 600mg dosage for general daily support.
  • Good review count indicating consumer satisfaction and reliability.
Cons
  • Contains a small amount of calcium carbonate, which is not essential for L-Lysine's primary goals.
  • Tablet form might be less preferred by some compared to capsules or powder.
