gayusasian82 saidHow do you know? You smell and compare farts?
Excess or I digested protein can result in a bloom of gut bacteria that produce nitrogen and sulfur based waste. Makes for stinky farts.
DudeInNOVA saidI can only use whey protein isolate because I cannot digest lactose. Not being able to digest certain proteins and sugars is not the same as being allergic to it.
Wrong. An intolerance is the inability to process or digest a substance, usually resulting in discomfort and possibly digestive damage. An allergy is a systemic reaction resulting in an immune response, such as hives, rash, or anaphylaxis. They are very different.
OP, have you tried whey isolate? It's much purer, and may help alleviate symptoms. Otherwise, there's a few options. Casein may still be fine, though it is dairy sourced. Also, soy. Don't worry about the estrogen thing, it isn't true. Check your local supplement store.
BCAAs may be an option. They aren't a full amino acid compliment, but they'll help with repair. Pure amino acid supplements also exist if all else fails.
Creatine is a whole different supplement, and is not a replacement for protein.
