2017's 10 Best
L-Leucine Supplements

L-Leucine For All Your BCAA Needs

L-Leucine is an amino acid that many who are concerned with their fitness find incredibly important. L-Leucine is usually found in BCAA products and, if you look carefully, it is usually the main ingredient found in BCAA supplements. BCAA’s generally have three different amino acids in them and L-Leucine is usually the largest in the ratio because studies have shown L-Leucine to be the most efficient of these amino acids in aiding in fitness.

L-Leucine is known mainly for it’s ability to stimulate the mTOR pathway, which is responsible for protein synthesis. This Muscle synthesis is the process used to absorb protein in order to repair and build bigger, stronger muscles. L-Leucine has some secondary effects on the body as well. For example, L-Leucine has been found to help aid lower blood glucose levels. If you want a high-quality L-Leucine supplement, look no further than our top 10 list of L-Leucine products.

#1 - Nutricost L-Leucine

The Standout: High-Quality, Easily Mixed, Best Value For Low Cost


Nutricost L-Leucine ranks #1 due to its lab tested, high quality instantized L-Leucine. Each scoop delivers a potent 5 grams, with each bottle providing a generous 100 servings. While other L-Leucine supplements have a tendency to clump and mix poorly, Nutricost's L-Leucine dissolves instantly for a smooth addition to any pre or post workout beverage.

Key Points:

  • 5 Grams L-Leucine
  • 500 Grams Per Bottle
  • 100 Servings Per Bottle
  • 20 Cents Per Seving
  • Boosts Protein Synthesis
  • Maximizes Muscle Growth
  • Best Tasting L-Leucine
  • Highest Mixability

L-Leucine is one of three branched-chain amino acids which plays a vital role in the growth and recovery of muscle mass, by stimulating protein synthesis via activating the mTOR pathway at lower concentrations, and at higher concentrations preserving muscle. Perfect for the athlete or individual looking to build or maintain muscle composition.

However, the cost of Nutricost's L-Leucine is the real drive home when it comes down to it. For $20, you get unbeatable quality that can be dose controlled to your preference.

#2 - Pro Supps L-Leucine Matrix

The Standout: Addition Of HMB And HICA, Best Price Vs Competitive Products, Safe


Coming in at a close second is Pro Supps' L-Leucine Matrix, which provides 3 grams of L-Leucine per serving, with the addition of the metabolites HMB and HICA for the most powerful muscle building formula. This powerhouse combination ensures maximal muscle growth in a safe, legal formula designed with one goal in mind: Build Muscle Fast. We especially recommend this product when trying to conserve muscle while reducing fat.

Key Points:

  • 3 Grams L-Leucine
  • 1.5 Grams HMB
  • 500 Mg HICA
  • 20 Cents Per Seving
  • Maximizes Protein Synthesis
  • Extreme Muscle Building
  • Innovative Ingredient Blend

L-Leucine is the only amino acid that can stimulate protein synthesis directly, which allows the body to be in a constant state of muscle building and preservation, while blocking muscle breakdown. HMB is a metabolite of Leucine, and is especially vital in inhibiting muscle breakdown. HMB is a substrate involved in Cholesterol synthesis, which is necessary for muscle cell shape and integrity. When muscle cell is damaged from exercise related exertion, the cell needs to repair the membrane before hypertrophy can occur.

HICA is another metabolite of Leucine. HICA has also been found to have anti-muscle breakdown effects, and been shown to be effective at reducing muscular soreness and boosting lean muscle mass.

If it's rapid muscle growth and recovery you're looking for, whether bulking or cutting, Pro Supps L-Leucine Matrix is an industry leader in L-Leucine supplements. Keep Reading »

#3 - Transparent Labs CoreSeries BCAA Glutamine

The Standout: Clean And Pure Quality, High Dosage, High Efficacy


Transparent Labs' CoreSeries BCAA Glutamine goes above and beyond most repair and recovery supplements, with 5 active ingredients. Each serving is backed with a clinically chosen blend, including 8 grams of BCAA in a 2:1:1 ratio with 5 grams of Glutamine, and 1 added gram Coconut Water extract for hydration support. That's a total of 13 grams Amino Acids in every scoop. You'd be hard pressed to find those numbers in the average BCAA supplement.

Key Points:

  • 8 Grams BCCA
  • 4 Grams Leucine
  • 5 Grams Glutamine
  • 1 Gram Coconut Water
  • Boosts Muscle Recovery
  • Supports Electrolyte Balance
  • Clinically Backed Ingredients
  • No Added Sweeteners or Dyes

Simple and straightforward, Transparent Labs carefully chooses scientifically backed ingredients for efficacy. Leucine, Isoleucine, and Valine are the three most essential branched chain amino acids that work synergystically to promote protein synthesis. L-Leucine and Valine activates the mTOR pathway, while Isoleucine acts as an anti-catabolic by reducing the rate of gluconeogenesis which halts muscle breakdown.

The addition of Glutamine makes BCAA Glutamine even more ideal, since Glutamine reduces the rate of Leucine oxidation, meaning more Leucine is available for triggering protein synthesis. This allows you to get every bang for your buck, ensuring that BCAA Glutamine is one of the most efficient BCAAs on the market today.

To top it off, this transparent formula contains zero dyes, no artificial colors, and no artificial preservatives, making it clean, simple and effective. Designed to stimulate protein synthesis, boost glucose metabolism, and minimize fatigue, CoreSeries BCAA Glutamine enhances overall performance. Keep Reading »

#4 - Gym Vixen BCAA

The Standout: Designed With Women In Mind, Amazing Taste

Gym Vixen's BCAA was specifically created for women, formulated with 6 Grams of BCAAs in the optimal 2:1:1 ratio. What really sets BCAA apart though is the inclusion of Casein (in the form of the PeptoPro Matrix), HICA, and additional minerals along with Vitamin B6.

  • Boosts Performance

Casein Hydrolysate enhances amino acid availability by increasing the incorporation rate of dietary amino acids into skeletal muscle protein to ensure faster absorption and usage. Delivered in the form of Peptopro, each molecule is so minuscule that no digestion is needed, allowing for the fastest absorption rate possible.

HICA, or alfa-hydroxyisocaproic acid, is a metabolite of the amino acid Leucine, and may be effective in binding the waste buildup that occurs during protein breakdown post exercise. It has been associated with both increased lean muscle mass, as well as a decrease in muscle soreness

Offered in two mouth-watering flavors, this is no ordinary 2:1:1 BCAA complex. Noted as one of the best tasting BCAAs on the market, some of our male readers might just be so inclined to try it too!
