A popular intra-workout BCAA supplement offering a high dose of branched-chain amino acids, L-Glutamine, and electrolytes for muscle recovery, performance support, and hydration, with a zero-calorie profile.
The XTEND Original BCAA formula is a well-established product in the sports nutrition market, primarily designed for intra-workout and post-workout recovery. Its core strength lies in the robust 7-gram blend of Branched-Chain Amino Acids (BCAAs) in the scientifically supported 2:1:1 ratio (Leucine:Isoleucine:Valine), which is crucial for stimulating muscle protein synthesis and aiding muscle repair. The addition of 2.5 grams of L-Glutamine further supports recovery, gut health, and immune function, which are beneficial for active individuals. The electrolyte blend provides basic hydration support, though for very intense or prolonged exercise, a more comprehensive electrolyte profile might be needed. The 1 gram of Citrulline Malate is a nice touch for promoting blood flow and reducing fatigue, although it's on the lower end of the clinically effective dose for significant performance enhancement. The zero-calorie, zero-carbohydrate profile makes it versatile for various dietary goals, from weight loss to muscle gain, as it doesn't add unwanted macros. Online reviews generally praise its taste and effectiveness for recovery and reducing muscle soreness.
- High dose of BCAAs (7g) in the optimal 2:1:1 ratio for muscle protein synthesis and recovery.
- Includes 2.5g of L-Glutamine, beneficial for muscle repair, gut health, and immune support.
- Zero calories and carbohydrates, making it suitable for various dietary plans and flexible for intra-workout use.
- Contains electrolytes (Sodium, Potassium) to aid hydration during exercise.
- The 1g dosage of Citrulline Malate is lower than the typically recommended effective dose (6-8g) for significant performance benefits like increased pumps or endurance.
- While it contains electrolytes, the blend might not be sufficient for individuals undergoing very intense, prolonged workouts or heavy sweating, potentially requiring additional electrolyte supplementation.
- The reliance on artificial flavors and sweeteners might be a concern for some users seeking more natural ingredients.
- Individuals with pre-existing kidney conditions should consult a healthcare professional before using high-amino acid supplements.
- Excessive intake of BCAAs without adequate intake of other essential amino acids could theoretically lead to amino acid imbalances over time, though unlikely at recommended doses in active individuals.
