What is L-Lysine?
L-Lysine is one of the essential building blocks of keratin and collagen – two proteins that help give hair its structure and strength. While the body can’t make it on its own, getting enough through diet or supplementation helps support normal hair growth and resilience, especially during times of stress or imbalance.
A Brief History of L-Lysine
From discovery to daily wellness essential
L-Lysine is first identified in milk protein
In 1902, German chemists first isolated L-Lysine from milk casein, uncovering one of the body’s essential amino acids – a nutrient that must come from diet or supplementation. This discovery laid the foundation for understanding how amino acids contribute to growth, repair, and healthy tissue development.
L-Lysine becomes known for its role in growth and repair
By the mid-20th century, scientists confirmed L-Lysine’s role in protein synthesis, tissue regeneration, and immune function. As research expanded, it became clear that adequate levels of L-Lysine were vital not only for overall wellbeing but also for maintaining strong hair and skin.
L-Lysine earns recognition in hair health research
Modern studies highlighted how L-Lysine supports keratin and collagen formation and assists in nutrient absorption – both key for maintaining healthy hair growth. Today, it’s a cornerstone ingredient in advanced hair supplements like Anavive.

L-Lysine FAQs
What does L-Lysine do to hair?
L-Lysine is an essential amino acid that contributes to normal protein formation in the body. Since hair is made primarily of keratin, which relies on amino acids as building blocks, adequate L-Lysine intake helps maintain the structures that support strong, healthy hair. It also plays a role in collagen production, supporting scalp and follicle integrity.
Can L-Lysine help with thinning hair?
L-Lysine alone can’t prevent or reverse thinning, but it supports key processes that contribute to overall hair health. It helps the body absorb nutrients like iron and zinc, which are both important for normal hair growth. By maintaining balanced nutrition and protein synthesis, L-Lysine can help create the conditions for healthier, stronger hair over time.
Is L-Lysine safe to take daily?
Yes, L-Lysine is considered safe for daily use within normal supplemental ranges. It’s an essential nutrient that must come from diet or supplementation, and excess amounts are typically excreted by the body. As with all supplements, it’s best taken according to the product directions, and you should consult your GP or pharmacist if you’re pregnant, breastfeeding, or taking medication.
Who might consider L-Lysine in their routine?
People looking to support protein intake, those on restrictive or low-protein diets, or anyone building a comprehensive hair wellness routine that includes balanced nutrition, stress management, and gentle hair care.
Can I take L-Lysine with other vitamins and minerals like iron or zinc?
L-Lysine is commonly combined with a balanced vitamin and mineral formula. If you are sensitive, take supplements with food. If you have been advised to take iron or any prescription medicine, speak to your GP or pharmacist about timing.
Is L-Lysine suitable for vegans and vegetarians?
Yes. L-Lysine used in food supplements is typically suitable for vegan and vegetarian diets. Anavive is vegan, and allergen-free.
