Amino Acid - L-Cysteine

Rather than recite the same information carried across many websites & quoting the same references, I (GP) will try and keep the information relevant to why you've probably searched the Gym Professor site - hair loss products (or better phrased: the promotion of hair growth)?

L-Cysteine can be found among the ingredients list of many hair growth formula's. The reason, growth (& health) of hair depends on adequate levels of L-Cysteine. Although L-Cysteine's a non-essential amino acid (can be made by the body), we've already touched on why consumption of "non-essential" (I'll encase "non-essential" in speech marks in this instance, considering it's a term ONLY!) amino acids are still important through your food intake (a healthy balanced diet will contain many sources of L-Cysteine - poultry, eggs, wheat, broccoli, onions, red peppers).

As regards L-Cysteine's supplementation in the matter of hair growth, having known a couple of people suffer slight hair loss & poor hair health through no apparent predisposition, which would now appear to be attributable to poor nutrition, in their instances (so they felt at least), a greater initial improvement ("jump start") was experienced by supplementing 1g of L-Cysteine daily (for only a couple of weeks) in conjunction with their improved (& continued) eating habits. Of course some people are more predisposed to hair loss than others. A healthy balanced diet may have a lessening effect (& will certainly be beneficial in many other ways), but don't expect miracles from hair growth formula's.

Contraindications: Diabetes and Cystinuria.
