1,000mg L-Leucine Powder
This is the straightforward way to add leucine to your training-day routine without changing anything else in your stack.
Our L-Leucine powder is a single-ingredient, measure-it-yourself format. It comes as a 1 gram pack with a clear dose: 1,000mg per 1 gram pack. Nothing blended, nothing hidden—just the compound named on the front.
- Each 1 gram pack contains 1,000mg of L-Leucine, supporting the signals for muscle protein synthesis and helping you keep your intake consistent around training.
Use it the way you use the rest of your essentials. Mix into water or your usual shake, and give it a firm shake or quick blend to disperse. Many people place leucine around training—pre, intra or post—or between meals with protein. Because this is a single-ingredient powder, it fits cleanly alongside whey, essential amino acids, creatine, electrolytes or whatever you already rely on. You control the amount; the pack is not a serving. Measure your intake with your preferred scoop or scale to match your targets.
The point here is precision. If you prefer to tune leucine independently rather than rely on whatever is bundled into a flavored mix, this gives you that control. It’s also a practical way to keep your routine the same across days while adjusting only one variable. No proprietary blends, no added actives—just L-Leucine at a labeled amount so you always know what you are adding.
Ingredients: L-Leucine.

Frequently Asked Questions
L-Leucine is an essential amino acid, meaning it must come from the diet. It is one of the three branched-chain amino acids, along with isoleucine and valine, and is present in many protein-rich foods.
Leucine participates in signaling related to muscle protein synthesis, which is why it appears in many fitness products. Evidence does not consistently show that isolated leucine improves performance or muscle gains beyond adequate high-quality dietary protein and training.
No. L-Leucine supplies one essential amino acid, while a complete protein supplies all nine essential amino acids. Consider the powder in the context of total dietary protein and follow the product label.
