Walk into any supplement aisle in Australia and you’ll see both “whey protein” and “whey protein isolate” on the shelf. The difference comes down to processing – and it matters more than most people realise.
What Makes Isolate Different
Whey concentrate is minimally processed, retaining more lactose and fat. Whey protein isolate, like Biotic’s Gain Banana, goes through additional filtering to strip out most of the fat and lactose, leaving a higher percentage of pure protein per scoop – 25g per serving, plus 5.5g of BCAAs.
Who Should Choose Isolate
- Anyone lactose sensitive or prone to bloating from concentrate
- Those tracking macros closely who want minimal carbs and fat
- Athletes wanting faster-absorbing protein post-workout
Where to Buy
Biotic’s Gain Whey Protein Isolate – Banana, 2lb, is available now on Amazon Australia.
