Analysis

Swanson Ultra's AjiPure L-Leucine provides 500mg of L-Leucine, a foundational building block for muscle and a potent stimulator of muscle protein synthesis (MPS). This directly addresses the goals of Muscle Gain, Fitness, and Weight Gain by supporting muscle repair and growth. While effective, many studies suggest optimal MPS stimulation often requires L-Leucine doses closer to 2-3 grams per serving, or larger doses taken multiple times a day. Its affordability and direct delivery of pure L-Leucine are strengths, but its dose may be considered moderate by some.

Pros
  • Directly provides L-Leucine, essential for muscle protein synthesis.
  • Good value for a pure L-Leucine product.
  • Simple, single-ingredient formula.
Cons
  • 500mg L-Leucine per serving is a relatively low dose for optimal muscle protein synthesis, often necessitating multiple servings.
  • Does not provide the full spectrum of BCAAs or EAAs, which might be more beneficial for comprehensive muscle support.
Warnings
  • Users should be aware that higher doses or combination with other amino acids might be necessary for maximum effectiveness towards muscle gain goals.

L-Leucine 500 mg
Adults 18–50 Vegetarian
Categories
Leucine 80.0
It is a pure L-Leucine product, making it directly relevant to the collection. The score reflects its moderate dose, as higher potency options exist within the market.
Goals
Muscle Gain 75.0
L-Leucine is crucial for muscle protein synthesis, and this product provides it directly. However, the 500mg dose is often considered sub-optimal for significant muscle gain and may require multiple servings.
Fitness 70.0
L-Leucine aids in recovery and muscle maintenance, supporting overall fitness. While beneficial, a higher dose or a BCAA/EAA complex might offer more comprehensive fitness support.
Weight Gain 70.0
By supporting muscle mass, L-Leucine can contribute to healthy weight gain. The single ingredient at 500mg is a good start but might not be sufficient on its own for aggressive weight gain goals.
