Informed BCAA Powder

The very best BCAA supplement from Bulk™, offering an incredible 18g of amino acids and 10g of BCAAs per serving with less than 1g of carbs and fat. Lab tested for banned substances and approved for professional athletes. If you don’t love it, we’ll give you your money back.

BCAAs are a specific form of essential amino acid that comprise about ⅓ of the protein in our muscles, and can only be obtained from the diet.. Our Informed BCAA™ formula provides an incredible amount of BCAAs in a precise ratio, produced to meet the strict nutritional requirements of professional, competitive athletes.

Each 21g serving of Informed BCAA™ contains an impressive 18g of essential amino acids. Of these 18g, 10g are the BCAAs leucine, isoleucine and valine measured out in a precise 8:1:1 ratio, while the rest contains equal parts glutamine, arginine alpha-ketoglutarate, alanine and glycine. The result is an incredible BCAA supplement that provides every amino acid you need to train to your full potential.

  • BCAAs: Leucine, Isoleucine and Valine (8:1:1 ratio)
    Leucine is considered the holy grail of amino acids. We complemented an 8g dose with 1g each of isoleucine and valine.
  • Arginine Alpha-Ketoglutarate
    Two molecules of the essential amino acid arginine, bound to one molecule of alpha-ketoglutarate.
  • Glutamine
    The most abundant amino acid in muscle tissue.
  • Alanine
    The second most abundant amino acid in muscle tissue and a unique addition to Informed BCAA™.
  • Glycine
    Similar to alanine, a final inclusion to round off this blend.

The Purpose

The Purpose

Like every product in our Bulk™ PRO series, Informed BCAA™ is designed for professional athletes and serious trainers. It’s produced to the highest standards using ingredients from industry-leading manufacturers, and every batch is tested for banned substances in an ISO 17025 accredited laboratory under the renowned Informed Sport programme. We also test every batch with a separate independent laboratory to verify its nutritional content, paying close attention to protein levels. If a batch doesn’t meet our rigorous standards, we reject it.

If for any reason you’re not happy with your purchase, however, and have not used an unreasonable amount, simply return it to our specified returns address within 28 days of purchase and we’ll credit your customer account with Bulk™ credit to the value of the returned product.
