## Description

L-Cystine should not be confused with cysteine, from which it is derived. Cystine is an oxidized dimer form of the amino acid, cysteine, that is common in many foods such as eggs, meat, dairy products, and whole grains. L-Cystine is most well known for its use in hair care products as a strengthening agent.* It also has other important uses and benefits.* L-Cystine is believed to play a role in protein synthesis, supports the heart, cardiovascular system, and lungs.* L-Cystine helps to maintain healthy blood vessels by supporting collagen production, which is critical for cardiovascular health.* The amino acid is needed to make elastin, another protein that supports heart health by maintaining elasticity of blood vessels.* L-Cystine is a non-essential amino acid that contributes to the formation of keratin, which is a major component of hair, nails and skin.* L-Cystine also helps maintain healthy cell membranes and supports cardiovascular health.* It may also aid memory, focus, and contribute to a calm sense of well-being. In addition, Cystine may help also support the hair.* This is the powder form.

Review: Fountain of youth, no kidding. Do not bother with NAD+, NAC, etc. This plus bulk glycine, taurine, AAKG, and TMG is my health recovery/longetivity cocktail. And it’s CHEAP.
Review: Whatever this is, it is not soluble at all, as if it is silica-gls . It drops to the bottom of a glass and stays there does not dissolve even in hot water and it doesn't dissolve even after days. It doesn't dissolve in blender. I tried to share this with Bulk Supplements and they never acknowledged or offered concern or resolution. They don't care it caused hrm and isn't ingestable. I don't think this product is sfe now. I do not recommend buying it nor trust BulkSupplements now.

*by E***N on 17 June 2018*

Seems to be helping... the only thing is that I've read that this works best in the body when taking Vitamin B supplements and I've never liked the smell of those, but I'm taking that now to help the process.
