Applications of N-Acetylcysteine (NAC) – From Addiction to Autism (By Prof Berk)
Does NAC supplement lighten the skin?
NAC supplement does help lighten the skin because the antioxidant glutathione stimulates a lighter version of melanin in the skin, making it appear bleached.
In a study, mild to strong bleaching of skin was observed in 90% of women who were prescribed NAC and hydroquinone for a skin condition known as melasma.
Glutathione, an antioxidant produced by NAC inhibits the enzyme tyrosinase responsible for pigmentation. It helps reduce dark spots and brighten the skin. The antioxidant effect further reduces cell damage leading to wrinkles, inflammation, and pigmentation.
A topical cosmetic preparation containing NAC was patented and marketed as a product for skin lightening as an alternative choice to cosmetics containing chemicals.
What are the benefits of NAC for hair?
Following are the benefits of NAC for hair:
- It may promote hair growth by providing essential nutrients. Hair contains about 14% L-cysteine, an amino acid that is derived from NAC. L-cysteine plays an essential role in hair formation and also prevents the breakage of hair strands. A study shows that oral administration of NAC for a phycological condition resulted in hair regrowth after 16 weeks of treatment.
- NAC may also help in the healthy appearance of hair, prevent hair loss, and support faster hair growth. There are supplements marketed for the same claims. However, there are no clinical studies to validate these claims.
Is NAC good for sleep?
NAC is good for sleep because it stimulates the production of neurotransmitter GABA which calms the mind helping with better sleep. It also increases the level of glutathione which may support longer and a night of better sleep.
It also reduces mucus content in the throat, maintains airway clearance, and prevents mucus hypersecretion helping patients with obstructive sleep apnea to get a sound sleep.
In a study, a 30 days treatment with NAC in patients with obstructive sleep apnea improved sleep and decreased apnea as compared to the control.
Some experts suggest taking NAC for improving sleep instead sleep medications which may cause addiction.
