By Jessica Kelley | Health


Many people develop acne. In fact, this is one of the most common skin condition affecting both men and women. This condition primarily affects teenagers who are undergoing hormonal changes. The condition, however, can affect adults.

The search for the perfect treatment for this condition is never ending. Today, one of the most promising treatments for acne is L-lysine supplement.

What is L-lysine?

L-lysine is an essential amino acid, which is a building block of protein. Since the human body does not create L-lysine naturally, this essential amino acid is introduced into our bodies through the food that we eat or through the supplements we take.

L-lysine offers several benefits for the body. One of these advantages is the treatment for acne.

Treating Acne with L-lysine Supplements

It has been noted that L-lysine helps prevent and treat acne. It can treat blackheads, pimples, and zits. Ultimately, it can leave the skin clean and acne-free.

The primary functions of L-lysine involve collagen formation and skin tissue repair, making this amino acid effective in treating acne.

 Also, this amino acid has been recommended for the treatment of viral infections like shingles, herpes, and cold sores.

Some L-lysine supplement users have also noted that their wrinkles and fine lines have significantly reduced.

With all these great effects on the skin and not just for the treatment of acne, L-lysine supplements may be the acne treatment product that you have been looking for.

Dietary Sources and Supplement Availability of L-lysine



L-lysine can be found in foods that are rich in proteins like red meat, poultry, and pork. Also, this can be found in cheese, eggs, and soybeans. You can find L-lysine in certain types of fish like sardines and cod fish.

Yeast, beans and other legumes also contain l-lysine.

L-lysine supplements are available in capsules and tablets. You can also find creams and liquids of L-lysine.

Recommended Dosage of L-lysine Supplement

According to health experts, the daily recommended dosage of the L-lysine supplement is 12mg per kilogram of body weight. A person who weighs about 150 pounds should need about 800mg of L-lysine daily.

For the treatment of acne, however, the dosage may be increased at 9,000mg per day as needed. It is important to speak with your health care provider so the right dosage can be computed depending on the severity of your acne.

Precautions to Consider when Taking L-lysine


Due to the potential drug to drug interactions and side effects of taking the L-lysine supplement, it is always best to consult your healthcare provider before taking the medication for acne treatment.

L-lysine increases calcium absorption in the body. Thus, you should be cautious in taking large amounts of calcium while taking the supplement. Also, excessive intake of the L-lysine supplement has been linked to gallstone formation and renal dysfunction.

If you have pre-existing health conditions like liver disease or kidney disease, it is best to consult your healthcare provider before taking the supplement.

While L-lysine supplements may have been proven to work well with the acne, it is always best to consult your health care provider before starting an L-lysine treatment for acne.
