NOW L-Arginine & L-Ornithine combines two essential amino acids in an ideal dietary supplement. Of these, L-ornithine is not usually included in proteins.
These two amino acids play an important role in the urea cycle by removing toxic ammonia and in stimulating the pituitary gland by releasing growth hormone. Growth hormone is very important for the growth and development of children, as well as for the muscles of adults.
L-arginine is a precursor of two substances found in semen and called spermidine and spermine. This amino acid is a particularly rich component of seminal fluid and constitutes 80% of this substance. Numerous studies report the use of arginine supplements to address male infertility. L-arginine can help address male infertility by improving sperm production and motility.
Wound healing can be accelerated with the use of L-arginine and/or L-ornithine supplements. It appears that these two amino acids stimulate collagen formation.
L-arginine improves the bioavailability of nitric oxide (a powerful vasodilator) and thus plays an important role in heart health and blood circulation.
