L-Lysine is an essential amino acid your body cannot produce on its own, making dietary or supplemental sources key to supporting overall health. Natural Factors L-Lysine 1000mg Tablets are formulated to support collagen formation, help reduce the recurrence of cold sores caused by the herpes simplex virus, and contribute to the maintenance of good health. Whether you're focused on skin resilience, recovery, or immune support, this straightforward supplement delivers meaningful results.
Key Benefits
- Supports collagen formation for healthy skin, connective tissue, and wound healing
- Helps reduce the frequency of herpes simplex virus (HSV) outbreaks, including cold sores
- Provides a reliable source of an essential amino acid your body depends on daily

Best For
