Why Choose This Product
MUSCLE REPAIR
Contains the three essential amino acids your muscles need most — leucine, isoleucine, and valine in free-form for direct utilization.
GROWTH SUPPORT
Helps maintain muscle mass with a 2:1:1 ratio that mirrors what research shows works best for muscle protein synthesis.
FAST ABSORPTION
Free-form amino acids bypass digestion and go straight to work, unlike protein powders that need breaking down first.

How It Works
How It Works
Your body can't make leucine, isoleucine, and valine — the three branched-chain amino acids that make up about 35% of your muscle protein. Unlike other amino acids, BCAAs are metabolized directly in muscle tissue rather than the liver, making them immediately available for muscle protein synthesis and repair processes.
Who It's For
Athletes and fitness enthusiasts who train regularly and want to support muscle recovery between sessions. Anyone following a calorie-restricted diet who wants to help maintain muscle mass while losing fat.
Who It's Not For
If you're already consuming 25-30g of complete protein within 2 hours of training, additional BCAAs may be redundant. Those with maple syrup urine disease should avoid BCAA supplements.
About This Product
What It Does
NOW BCAAs help maintain muscle tissue and support recovery after exercise. These three essential amino acids — leucine, isoleucine, and valine — are the building blocks your muscles use most during repair and growth processes.
Why It Works
- LEUCINE (1,600mg): The primary trigger for muscle protein synthesis, shown in research to activate mTOR pathways that signal muscle building.
- ISOLEUCINE (800mg): Supports muscle glucose uptake and helps maintain nitrogen balance during training stress.
- VALINE (800mg): Works with the other BCAAs to prevent muscle breakdown and support energy production in muscle tissue.
What's Inside
Pure free-form amino acids in vegetarian capsules. No salt, starch, yeast, wheat, gluten, soy, egg, shellfish or preservatives. Each 4-capsule serving delivers 3.2g of BCAAs in the researched 2:1:1 ratio.
Why we carry it: NOW's pharmaceutical manufacturing standards ensure consistent potency and purity at a price that makes daily BCAA supplementation accessible to serious athletes.
