Leucine is a branched-chain amino acid, or BCAA, that is an essential source of energy for your muscles. Amino acids are the building blocks of protein, and therefore leucine plays an important role in protecting, fueling and repairing your muscles. This amino acid is also called L-leucine, or D-leucine.
Daily Intake
The branched-chain amino acids are often supplemented and taken together. According to Nutros.com, your requirements for leucine will depend on your weight, but an intake of 5 grams of leucine, in combination with 4 grams of valine, and 2 grams of isoleucine per day, may be healthy. People who are active may use leucine, in combination with valine and isoleucine, to help increase muscle gains.These needs can be met by adding whey protein powder to your diet. Talk to your doctor if you think you need to supplement your diet with leucine or if adding a leucine-rich whey protein product to your diet may help you gain and maintain muscle and energy.
Food Sources Of Leucine
You can find leucine naturally in protein-rich foods. This includes dairy products, such as milk, yogurt, and cheese. Other protein-rich foods that have leucine include red meat, chicken, turkey, and eggs. Other good sources include whey protein powder supplements, egg protein supplements, brown rice, nuts, whole grains, and beans.
Increased Muscle Gain And Endurance
Leucine can help your muscles recover and prevent muscle loss after exercise. According to Nutros.com, leucine can increase growth hormone production and help men maintain healthy levels of testosterone. Leucine can also increase your endurance by increasing the fuel your muscles have to work properly and by preserving energy stores in your muscles. If you become deficient in this amino acid, you may experience muscle breakdown and wasting, greater risk of high blood sugar, and a poorer ability to heal wounds. Typically, healthy people with a good diet are not deficient in any amino acids. Ask your doctor if you have any concerns.
Role In Pain Relief
D-leucine, a form of leucine, may be beneficial in relieving pain in your body. According to Nutros.com, D-leucine may aid in decreasing the breakdown of your body's naturally occurring pain killers. This can effectively result in the relief of pain. You can add more protein-rich foods in your daily diet to help boost your intake of this amino acid and gain this potential benefit.
