● Build Muscle
Bulk leucine is a popular supplement among bodybuilders and athletes because of its powerful effects on muscle building. 

●Prevent muscle loss
Leucine is thought to help slow muscle degeneration to reduce the effects of aging. A study conducted in the Department of Internal Medicine at the University of Texas Medical Branch and published in Clinical Nutrition showed that it helped improve muscle synthesis in older adults who consumed the recommended amount of protein per meal. Another human model conducted in France and mentioned above had similar findings and reported that leucine supplementation was also able to limit weight loss due to malnutrition in older participants.
●Performance enhancement
In addition to using bulk leucine for bodybuilding, professional and novice athletes alike often turn to this essential amino acid in hopes of taking their physical performance to the next level.

●Help with fat loss
If you're looking to build muscle and lose some extra body fat at the same time, then leucine may be just what you need. In fact, several studies have found that it can have some powerful effects when it comes to weight loss.
Animal models from the Department of Food Science and Experimental Nutrition at the University of São Paulo in Brazil showed that supplementing rats with low doses of leucine over six weeks resulted in fat loss compared to controls.
● Promotes muscle recovery
Research has uncovered some promising results regarding the potential role of leucine in muscle recovery. Another study conducted by the School of Sport and Exercise and the Institute of Food, Nutrition and Human Health at Massey University in New Zealand showed that supplementation with this amino acid improved recovery and high-intensity endurance performance for several days after training in male cyclists.
● Stabilize blood sugar
Some studies suggest that bulk leucine may help maintain normal blood sugar levels. A human study from the Division of Endocrinology, Metabolism and Nutrition at the Minneapolis VA Medical Center and published in Metabolism showed that leucine taken with glucose helped stimulate insulin secretion and lower blood glucose levels in participants.

 

●Malnutrition:
Lack of protein or insufficient bulk leucine in the diet may lead to decreased leucine levels.

●Liver disease:
The liver is an important organ for protein synthesis; if liver function is impaired, protein synthesis and leucine production may be affected.

●Digestive problems:
Certain intestinal disorders or absorption problems may affect the absorption and utilization of leucine.

●Chronic diseases:
Certain chronic conditions, such as kidney disease or intestinal disorders, may lead to decreased leucine levels.

●Other factors:
Certain medications, metabolic abnormalities, or genetic disorders may also lead to decreased leucine levels.

 

● Duration and effect of leucine intake after exercise
The post-exercise synthesis window is the period after exercise when the body is particularly receptive to absorbing nutrients. It lasts from 30 minutes to two hours. Leucine intake during this time can increase muscle protein synthesis rates by 20-30%. It depends on individual differences and the specifics of the exercise.

● Potential Side Effects of Pre-exercise Leucine Ingestion
Pre-exercise bulk leucine intake has its drawbacks. The resulting insulin surge may cause blood sugar levels to drop during exercise, leading to dizziness or even fainting.
Additionally, high pre-exercise leucine levels may redirect blood flow to the digestive system, thereby reducing blood flow to the muscles being used.

 

●Leucine levels vary by protein source
What should you eat to get enough protein and bulk leucine? It depends on the protein source you choose. Leucine, an essential amino acid, can only be obtained from food or supplements.

●Animal-based proteins are higher in leucine
Plant-based proteins are deficient in one or more of the essential amino acids. It is less effective at stimulating muscle protein synthesis, whereas dairy and animal-source proteins have a higher percentage of leucine.

In a recent study, subjects consumed 19 grams of isolated whey protein or 26 grams of isolated soy protein per day - both of which provided about 1.8 grams of leucine.

 

The World Health Organization recommends that adults need at least 39 mg/kg of bulk leucine supplementation per day. An intake of 1-3g of leucine per meal is recommended. Infants, developing adolescents, and athletes can take more leucine in moderation as needed. Generally people on a normal diet are not leucine deficient.

 

It is important to note that recent studies have indicated that the recommended amount of leucine should be higher in the elderly population. This is because there are differences in leucine metabolism in older people compared to younger people. Elderly people retain twice as much leucine in their guts as younger people. And the stimulatory effect of leucine on muscle protein synthesizing capacity decreases with age.
