When it comes to overall health and wellness, there are a few differences between the needs of men and women. While everyone needs to obtain essential amino acids from external sources, some of these nutrients are more important than others for each sex. Because men have unique needs and goals for their health and appearance, there are certain amino acids that may be beneficial for men to include in their diet and skin care regimens.
Here are just some of the benefits that amino acids can have for men’s health and wellness.
Promote Muscle Growth and Repair
Amino acids are perhaps best known for their role in muscle growth and repair, as they are the building blocks for all proteins. In particular, the amino acids arginine, methionine, and glycine combine to form creatine, a naturally occurring tripeptide that helps to supply energy to muscle tissue in order to promote optimum muscle repair, growth, and performance .
While each of the 20 amino acids involved in protein synthesis have a unique set of functions, the best way to reap their many benefits is to combine amino acids in the right sequences, such as those that join together to form creatine.
Improve Male Fertility
Men struggling with low sperm count may benefit from adding foods rich in amino acids to their diets. Arginine, for example, is converted to nitric oxide (NO) within the body. NO has been shown to play a key role in improving sperm health, both by increasing blood circulation and activating a certain pathway called the guanylate cyclase (sGC)/cGMP pathway, which, in turn, improves sperm motility .
When combined with zinc, lysine may also help to increase sperm count, although more research is needed to provide definitive evidence of this potential benefit.
For many men, the first signs of aging skin can be the cause for lowered self-confidence, and this may be made even more difficult by the sea of anti-aging products that seem to be marketed solely to women. The truth is, however, that men also have concerns about the appearance of aging sun-damaged skin, and amino acids can help.
Because they are the building blocks of proteins like collagen and elastin, topical amino acids can significantly improve the appearance of lines, wrinkles, and dark under eye circles by boosting your skin’s natural collagen production. A combination of branched chain amino acids, arginine, glycine, and proline has also been shown to reverse the harmful effects of UV radiation on the skin, restoring a more even and healthier-looking complexion .
Fight Hair Loss
Hair thinning and loss is a common cosmetic concern for men, but many may not want to seek surgical treatment options. Instead, amino acids may help to combat hair loss and restore a younger appearance. This is because human hair consists of a protein called keratin, which is made up of four main amino acids: lysine, cysteine, arginine, and methionine . Thus, using the right combination of amino acids may help to stimulate keratin production and promote hair growth while simultaneously working to prevent premature hair loss.
Some evidence suggests that a deficiency in the essential amino acids may lead to excess “bad” cholesterol, which is a marker for a number of cardiovascular health concerns. Without enough of all of the amino acids–both those that are naturally produced by the body and those that must be obtained from external sources–your body cannot synthesize a particular protein called high-density lipoprotein (HDL), which is directly linked with heart health .
Additional research has found that the two sulfur-containing amino acids–cysteine and methionine–may help to lower cholesterol levels as well .
While both men and women can benefit from eating amino-acid-rich foods and using topical amino acids for improved hair and skin function and appearance, men often have unique medical and cosmetic concerns that could be addressed through amino acid therapy.
