Everything you need to know about this product.
What is Nature's Sunshine l-Lysine?
Nature's Sunshine l-Lysine is an essential amino acid supplement that supports the body's circulatory and immune systems. Each capsule provides 450 mg of l-Lysine, which may help strengthen blood circulation, balance acid and alkaline levels, and assist the immune system in creating antibodies.
How do I take l-Lysine?
Take 1 capsule with a meal three times daily. Each bottle contains 100 capsules, providing approximately a 33-day supply at the recommended serving.
Who is l-Lysine a good fit for?
l-Lysine is well-suited for adults looking to support their cardiovascular health, immune function, or musculoskeletal system. It's also a great choice for those interested in supporting calcium absorption and bone density. The capsules are both vegan and vegetarian friendly. As always, anyone who is pregnant, nursing, or on medication should check with their healthcare provider first.
What makes l-Lysine an essential amino acid?
An essential amino acid is one the body cannot produce on its own, so it must be obtained through diet or supplementation. l-Lysine plays an important role in supporting immune response, healthy circulation, and helping the body maintain a balanced acid-alkaline environment.
How does l-Lysine compare to other supportive products in the range?
l-Lysine focuses on amino acid support for circulation, immune function, and calcium absorption. For those specifically looking to support bone density through minerals, Calcium-Magnesium (SynerPro) may be a complementary option. If cardiovascular support is a primary goal, Solstic Cardio or Mega-Chel are also worth exploring alongside l-Lysine.

- Melinda Beasley9/15/2025Behcets Syndrome
As far back as I can remember as a very young child until my early 20s, I had major outbreaks on my lips. When I was pregnant with my first child, the neighborhood pharmacy was like a clinic also because Mr. John knew so much about herbs and medicine. I did have an outbreak on my lips, and Mr. John said that if I’m not pregnant that I can take l-lysine and it would control it I was pregnant so I couldn’t take it but after nursing my child was over, my next outbreak on my lips, I remembered what he said. Every time I felt a tingle I would take a lysine and it would go away. later on in life I learned about Behcets Syndrome and realized that’s what I have. Getting angry being nervous high stress, anxiety brings out the outburst and outbreaks. It is not just a lip thing. It matters the quality of l-lysine Because there are others out there that do not come close to controlling my outbrakes. I am 59 years old. Trust me when I tell you it’s been tested. I’ve been using nature sunshine since my daughter was born in 1984. She will be 40 years old this year and caring sunshine has been wonderful to me.
- Lisa Stith9/15/2025l-Lysine
Great quality and price. Easy to swallow. Most other brands are too big and hard to swallow. Also, fast delivery and great customer service.
- Devon9/15/2025l-Lysine for fever blister prevention
I take the l-Lysine for the prevention of fever blisters and it seems to really help. I had zero blisters as long as I was taking this product. When I recently got another blister, I immediately reordered.
- Steve Strom9/15/2025Great service
Dependable and quick deliveries.
- Amy Barker9/15/2025Helps with herpes
I contracted vaginal herpes from a toilet seat decades ago. It flares up from time to time. When it does, if I take L-Lysine right away and stay on it, it can prevent the sore from erupting, and reduce the time of the flare-up (which is usually a painful two weeks).
