Primaforce Pure L-Leucine Powder | 5g per Serving | Increases Muscle Growth & Lean Body Mass | 10.7oz/300g; Exp 10/2028

 Leucine is one of only 3 branched chain amino acids (BCAAs) in the human body, and the most important. It’s ability to reduce muscle protein breakdown while promoting muscle protein synthesis is second to none. This 1 - 2 punch is why people who supplement with leucine experience greater muscle gains than those who do not. L-leucine is so powerful that most BCAA complexes contain as much leucine as the other two BCAAs combined.

BENEFITS

• Muscle Protein Synthesis Trigger: L-leucine directly activates the mTOR pathway, the master switch for muscle building. This makes it especially useful after workouts or during recovery, even without a full protein shake.
• Preserves Lean Muscle: During calorie restriction, illness, or aging, leucine helps reduce muscle breakdown. That is why it shows up often in formulas for athletes, older adults, and anyone cutting weight.
• Supports Strength & Recovery: By signaling muscle repair sooner, leucine can shorten recovery windows and support gains in strength when paired with resistance training.
• Metabolic & Insulin Support: Leucine helps regulate blood sugar by supporting insulin signaling and glucose uptake into muscle cells. Muscles fed properly behave better metabolically.
• Helps Prevent Age-Related Muscle Loss: Research on sarcopenia shows leucine plays a key role in maintaining muscle mass and function as we age, especially when dietary protein intake is low.

Flexible & Fast-Acting

As a powder, leucine is:

• Easy to stack with whey, EAAs, or collagen
• Rapidly absorbed
• Neutral in taste and low in calories

Who Benefits Most?

• Athletes & gym-goers
• People on low-protein or plant-based diets
• Older adults focused on muscle maintenance
• Anyone in a calorie deficit

Directions

As a dietary supplement, mix 1/2 - 1 scoop with 300ml of water and take on an empty stomach or as directed by your healthcare professional.

Do Not Take if: You are taking insulin and other antidiabetic medications: Leucine can stimulate insulin secretion and may further lower blood glucose levels.
