How to Use L-Carnitine & Glutamine Together

Amino acids provide a wide range of benefits, from tissue repair to increased metabolism. L-carnitine comes from the amino acids lysine and methionine and helps the body burn fat as an energy source, according to the National Institutes of Health Office of Dietary Supplements. Glutamine is a type of amino acid that aids in immune system function and muscle repair, notes the University of Maryland Medical Center. Supplementing your diet with l-carnitine and glutamine can be beneficial to your health.

Step 1

Talk to your doctor before adding l-carnitine and glutamine to your diet. Ask about possible side effects or drug interactions associated with l-carnitine and glutamine supplements.

Step 2

Consume l-carnitine in pill form once per day. Take 2 to 4 grams of l-carnitine about an hour before exercising to help burn fat.

Step 3

Take l-carnitine in liquid form if you don't like taking pills. Add liquid l-carnitine to your favorite juice or take it alone.

Step 4

Consume 5 to 10 grams of glutamine three times per day. Take glutamine in pill form with breakfast lunch and dinner.

Step 5

Mix glutamine powder with cold water or juice, if you prefer taking supplements in liquid form. Drink a serving with a meal three times per day. Avoid adding it to hot beverages because heat destroys glutamine, according to the University of Maryland Medical Center.


Avoid d-carnitine while taking l-carnitine because it may interfere with the natural form of l-carnitine and possibly cause undesirable side effects, states the University of Maryland Medical Center..
