L-Leucine is a type of amino acid which is derived from reactions taking place between pancreatic enzymes and protein. Adults need leucine to keep nitrogen balanced in their systems while children need it to keep up satisfactory rates of growth. Valine, leucine, and isoleucine make up one of the chains called BCAAÆs or branch chain amino acids. They make up a large amount of the bodyÆs total protein structure.

Through some research I've discovered some important things about when and how to take Leucine.
1) Do not take before your workout. Leucine stimulates the production of glycogen from glucose, and simultaneously prevents glycogen's breakdown into glucose, so you won't be getting enough energy to your muscles during your workout.
2) Do not take leucine without food or in a fasted state. if you want to prevent catabolism, or muscle breakdown, take HMB. Leucine should be reserved for times you want to promote muscle synthesis, or anabolism.
3) Do not take leucine consistently throughout the day. Leucine can cause insulin resistance when taken in large amounts and too consistently.
4) Do not take in the morning. This is not an optimum time to build muscle anyway, as your body's natural cortisol spike is then. Wait until afternoon/evening.
1) Take leucine with meals. Leucine signals muscle...
I have been using several Bulk Supplements for years, including L-Leucine. My gains with the Bulk Supplement products have been equal to or better than when I try the big name/big cost supplements. I go each year to the gigantic expo at the Mr. Olympia and have come home with literally hundreds of supplements to try. None work any better than the Bulk Supplement products. I am 64 and a current NPC bodybuilding competitor and a Senior Olympics powerlifting competitor, so I pay a lot of attention to my supplements.
I purchased this after doing some research into body building and consistently seeing leucine mentioned as one of the most important amino acids to deliver after a workout. I looked for the recommended dosage, checked my regular whey protein supplement and realized it only delivers about half of the amount. I was already going to purchase another supplement from this seller, so grabbed another one as well. I have now been using is as recommended (1 tsp twice a day) and have seen some improvement in strength at the gym. However, this might also be attributed to the beta alanine supplement I purchased at the same time and have been using together with this one. In any way, I am happy with the purchase. The product dissolves well and it's a great price for the amount. The only drawback is the taste, it's really gross so I dissolve it in a half cup of milk, chug it and chase with a glass of water. It is not so noticeable when added to a full cup of milk and whey protein powder though.
