What's in the bag?

When we say 100% whey protein, we mean it. There is nothing else in the bag other than premium quality, natural protein powder. During manufacturing, a negligible amount (about 1%) of lecithin is added so that the powder will mix easily. Boomers add no flavouring, sweetener, bulking agents, additives, preservatives or anything else. Boomers is just the good stuff – Nothing else!

Boomers Quality Assurance & Production

We ensure all our suppliers maintain the integrity of our protein all through production via the most delicate extraction method - ultra-filtration and cross-flow microfiltration.

The manufacturing process is all done cold so that the result is all-natural whey protein, abundant in naturally-occurring branched-chain amino acids (BCAA’s) and 3 essential amino acids that produce glutathione which is vital for recovery, growth and disease resistance.

Some suppliers blend their protein powders with cheap fillers – Boomers Protein, however, has always been pure, since we were established in 1997.
