 Twinlab’s L-Arginine



Twinlab's L-Arginine is a complete and effective L-arginine formula especially designed for highly allergic people. L-arginine is a nonessential amino acid that may become conditionally essential if demand for it exceeds the body's ability to produce it. Certain conditions such as a vegan/vegetarian diet, prolonged exercise, or physical stress (such as infection, burns and injury) can deplete arginine levels, making adequate dietary intake or supplementation necessary.

Arginine is necessary for numerous physiological processes. This vital amino acid promotes hormone secretion (including growth hormone), assists in wound healing, removes excess ammonia from the body, helps the immune system function optimally, enhances protein synthesis in body tissues and promotes muscle growth. Arginine is a precursor to the neurotransmitter nitric oxide (NO). NO is responsible for increasing the diameter of the body's blood vessels (vasodilation), allowing increased blood flow to reach constricted areas.

Arginine supplementation can help elite athletes improve immunity and prevent infections following competition and intense exercise activity. Studies suggest that arginine's vasodilation effects can help support brain and sexual health. Arginine may also help people with serious infections, burns or other trauma.

Taking a supplement such as Twinlab's L-Arginine supplies the necessary nutrition you need to promote muscle building, boost immunity, and support brain and sexual health.


With all of the arginine supplements to choose from, what makes Twinlab's L-Arginine stand out from the rest? An important advantage is that Twin Lab's formula doesn't include common allergens, synthetic fillers, artificial sweeteners, preservatives, flavorings, tablet binders, coating or colorings. This can be of great benefit, especially if you're prone to fish, soy, dairy, corn, yeast, citrus or wheat allergies. Furthermore, Twin Lab's L-Arginine is formulated from free form amino acid for easy digestion and assimilation in the body.

Studies have found that the nutrients in L-Arginine have numerous benefits including:

  • Promotes muscle building
  • Enhances immunity
  • Supports brain and sexual health


Few side effects are associated with L-arginine supplementation. However, mega-dosing with L-arginine over an extended period of time may result in potential side effects such as diarrhea, weakness and nausea.

People with herpes virus (either cold sores or genital herpes), heart, kidney or liver disease should not supplement with L-arginine without consulting a physician.

At this time, there are no known drug interactions with L-arginine.

Is it for you?

If you're an athlete, bodybuilder or fitness enthusiast looking to build muscle and enhance immunity, you may benefit from Twinlab's L-Arginine. Vegans/vegetarians and highly allergic individuals may also find nutritional support with L-Arginine. However, people with herpes virus (either cold sores or genital herpes), heart, kidney or liver disease should not supplement with L-arginine without consulting a physician.
