L-Cysteine 500mg Capsules
L-Cysteine is a semi-essential sulfur-containing amino acid which is very integral to the endogenous antioxidant glutathione, which is currently known to be a powerful endogenous antioxidant. Actually, it has become common knowledge that glutathione is the only antioxidant able to recycle the body’s other antioxidants and has evolved as a common marker of cell survival. L-Cysteine in general is botanically utilized in disorder to maintain respiratory health, support detoxification pathways in the liver and mediate healthy keratin production, thus benefiting hair, skin, and nails.
Primary Actions
Supports Glutathione: Increases the synthesis of Glutathione, which protects cells against oxidative stress and damage from free radicals.
Respiratory Health: Acts as a mucolytic agent by breaking up and thinning mucus in the airways for freer breathing during chronic bronchitis or COPD.
Skin and Hair Care: Forming keratin, it reinforces the hair cuticle to eliminate frangibility and help to prevent the stretching of the skin.
Detoxification: Directly helps the liver neutralize toxins and heavy metals to assist in systemic metabolic elimination.
Enhances Immune Functions: It helps reduce cellular inflammation and, in this manner, supports the body’s natural defense system.

Frequently Asked Questions
Q: Is L-Cysteine the same as N-Acetyl Cysteine (NAC)?
The difference is apparent between L-Cysteine, the basic amino acid, and its acetylated “report,” NAC. N-acetylcysteine (NAC) is even more preferred in a clinical setting due to greater stability, absorption in due course by liver and lung; however, both are valuable glutathione precursors.
Q: Does L-Cysteine benefit hair loss?
L-Cysteine is one of the amino acids that can form disulfide bonds. Disulfide bonds are responsible for the while other amino acids disulfide-binding amino residues, providing both strength and rigidity to the keratin in hair. “Hair, Skin and Nails” formulations that contain L-Cysteine may very well help with hair loss and thinning.
Q: Why Does That Bottle Smell Like Rotten Eggs?
Both oxide-rich and sulfur-bearing L-Cysteine bear the smell. The slight smell is a natural characteristic of the raw material and does not indicate that the product is expired or spoiled.
Q: Should I Take Vitamin C with L-Cysteine?
It is, however, thought that the presence of lysine is far less dangerous than that of tryptophane. How then is the Niacin washed out of one’s body?
Many skincare procedures, such as acne treatment and scar-removal, would likely proceed with using light therapy in the form of LEDs (light-emitting diodes).
