Your body can't make essential amino acids itself, so they have to come from your diet - and this shake is a super-convenient way to do that, no matter what your dietary choices are.

Our blend is based on the same essential amino acid profile as our Impact Whey Protein, only it has a faster amino acid absorption rate*, and it's fortified with a 4:1:1 ratio of the BCAAs, leucine, isoleucine, and valine. These occur naturally in protein, which helps to build and repair new muscle.¹

Informed Choice Certified

A voluntary quality assurance programme, Informed Choice sets the global standard for quality and safety in sports nutrition. We're committed to delivering the highest quality and take pride in going the extra mile to ensure its purity, free from any impurities or banned substances.

Here's how Informed Choice works:

• First, the production process is monitored. It takes an extremely high standard to pass this stage of certification.
• Next, Impact EAA goes through pre-certification testing across multiple batches.
• Last, there's regular blind batch sampling, to make sure there are no impurities and banned substances.

Informed Choice rubber stamps supplements you can trust.
