Our 1000mg L-lysine supplement is designed to help promote muscle growth, accelerate weight loss, reduce anxiety, and improve your well-being. 


Lysine is an essential amino acid that the body cannot produce itself. A building block for proteins, it is needed for growth and the production of carnitine, the nutrient responsible for turning fatty acids into energy. Taking lysine is believed to help build muscles and lower cholesterol!

The Science

Scientific studies have revealed that L-lysine supplements can help to combat high blood pressure, relieve feelings of stress and anxiety, and regulate blood sugar levels.

This study suggested that consuming a sufficient amount of lysine could directly reduce blood pressure in individuals with hypertension.

Lysine supplementation resulted in normalisation/reduction of blood pressure of hypertensive subjects who have suboptimal lysine intake. The mean Systolic Blood Pressure (SBP) of the lysine-supplemented group significantly dropped from 146.11 to 128.95 mmHg. That of women also dropped from 144.12 to 132.28 mmHg, while the control group had there SBP remained fairly constant after 112 days of intervention with changes in men from 145.79 to 142.79 mmHg and women in the control had very little drop from 145.15 to 145.00 mmHg.

This study found that lysine inhibited protein glycation and enhanced glycemic control, suggesting it may help those with diabetes.

The significant decrease in the urine glucose of the supplemented group with Lysine is the reason for the beneficial effect of this amino acid on the renal function of the diabetic patients.

There aren’t any cures for cold sores, but studies have suggested that lysine may help to reduce the chances of a flare-up. Scientists believe that this is because lysine reduces the production of arginine, a chemical found in the body that the herpes simplex virus needs to reproduce.

L-lysine helps the body to heal wounds, thanks to its ability to form collagen. Collagen is used by the body to create skin and bones. A recent 2023 study found that applying lysine ointment helped to ulcers clear more quickly than a placebo.

As an anti-inflammatory, L-lysine has been found by scientists to help regulate the lining of the stomach and intestine, which some believe helps to reduce issues such as a leaky gut.
