Serine

Nonessential Micronutrient

OVERVIEW

Summary

A nonessential amino acid, serine is needed for the metabolism of fats as well as fatty acids. It is highly concentrated in all cell membranes and aids in the production of immunoglobulins and antibodies and thus is important in supporting a healthy immune system.

Other names for Serine

SER, amino acid S, 2-amino-3-hydroxy-propanoic acid

Where to find Serine

Serine is an amino acid found in meats and dairy products, wheat gluten, peanuts as well as soy products.

PERFORMANCE BENEFITS

Why athletes use Serine

An athlete may consume serine as part of his or her natural dietary nutrition plan to ensure efficient metabolism of fats. However, it’s not something that needs to be supplemented.

HEALTH BENEFITS

Signs of Serine deficiency

No deficiency conditions are known to exist.

DISCUSSION

More about Serine

Serine is a nonessential amino acid, which means it’s manufactured from other amino acids in the liver. It is essential for the metabolism of fats as well as fatty acids. It is highly concentrated in all cell membranes and aids in the production of immunoglobulins and antibodies and thus is important in supporting a healthy immune system.

The metabolism of serine leads to important production of choline and phospholipids, which are essential to form neurotransmitters (chemical messengers in the brain) and to stabilize cell membranes.

Serine is a precursor to many other amino acids such as cysteine and methionine and is thought to work in conjunction with alanine and glycine to stabilize blood sugar.

Finally, serine is also used in cosmetics as a natural moistening agent.

In conclusion

While there’s no doubt serine is necessary for a wide range of body functions, it just isn’t necessary to look for it in a supplement. Why? Because it’s found abundantly in foods, and our bodies easily produce it.

NOTES ON USAGE

Amount

Supplementation with serine is not necessary because it’s easily obtainable through foods and natural production in the body.

Timing

There is no specific optimal time to consume serine.

Synergists of Serine

Serine requires B vitamins for production. It’s also used with other amino acids.

Toxicity of Serine

No known toxicity.

Bans and restrictions
