insights Analysis
Natural Factors L-Lysine 500 mg offers 500mg of L-Lysine Hydrochloride per capsule, but indicates a serving size of 2 capsules to provide a 1000mg dose. This 1000mg daily dose is highly effective for supporting immune health, promoting collagen formation for skin, and aiding in hair protein synthesis. While Natural Factors is a well-regarded brand, known for quality and purity, its price per serving of 16 cents for the 1000mg dose is notably higher than many other available L-Lysine options. This makes it a less competitive choice for budget-conscious consumers, despite its efficacy and brand reputation.
- Offers an effective 1000mg daily dose (two 500mg capsules).
- From Natural Factors, a reputable brand in the supplement industry.
- Capsule form is generally easy to consume.
- High price per serving (16 cents for 1000mg), making it less cost-effective.
- Requires two capsules for the optimal 1000mg dose, which can be less convenient.
