2024's Top 10 L-Leucine Supplements
Find out what to look for in a quality L-Leucine supplement and what to watch out for
What is L-Leucine?
Leucine is one of only 3 branched chain amino acids (BCAAs) in the human body. BCAAs are renowned for their usefulness in exercise, sports, and overall fitness.
If you’re trying to build muscle, leucine’s ability to promote protein synthesis (a key component of muscle growth) is second to none.Most BCAA supplements contain leucine, isoleucine, and valine in a 2:1:1 ratio, meaning that there is as much leucine as the other two BCAAs combined!
L-Leucine Fights Fatigue
Studies show that supplementing with L-leucine before and during your workout may reduce the feeling of fatigue while increasing mental alertness.
L-Leucine Slows Muscle Breakdown
Muscle breakdown is normal to an extent. Protein needs to be broken down in order to be built back up bigger and stronger. But when protein breakdown exceeds protein synthesis, muscle loss occurs.
Studies show that supplementing with L-leucine can halt or significantly reduce protein breakdown from occurring while promoting protein synthesis.
L-Leucine Promotes Muscle Growth
L-leucine increases protein synthesis while slowing muscle breakdown. The result of this 1-2 punch is that people who use leucine experience greater muscle gains than those who do not.
One study found that subjects who drank an L-leucine supplement following a workout developed up to 22% more muscle mass than their placebo counterparts.
L-Leucine Reduces Soreness
Studies show that because L-leucine mitigates protein catabolism (breakdown) during and after your workouts, it prevents levels of creatine kinase from getting too high. Elevated levels of creatine kinase are a tell-tale sign of muscle damage and protein breakdown.
As a result, L-leucine may help to alleviate muscle soreness while promoting recovery.
