RE: Reflex Nutrition: MicroWhey vs InstantWhey?
Mircro Whey is an Isolate, very low in lactose fat and is naturally more expensive. Instant Whey is still very high quality and is one of the only whey blends that actually meets its label claims of protein percentage. It has slightly more carbs and fat but in the grand scheme is still low.
Taking into account value for money, Instant Whey is the better option. If you have some allergies or very anal about carbs and fat then MicroWhey is a good option.
