I purchased Vital Protein Pea Protein Isolate at Chemist Warehouse for $30, which gave me 500g of pea protein isolate. This is much more expensive than pea protein isolate sold online, for example, from Bulk Nutrients, but I was willing to give this a try.
What I notice from reading the back is that the amino acid profile is very good. Normally pea protein is mixed with rice protein to enhance amino acid profile, but the methionine and cystine levels in this protein powder seems to be high, which may be a result of the way they isolate the protein from the pea.
I put a tablespoon onto a glass of water. It is a very mixable protein powder. It didn't take too much mixing to dissolve the powder into the water. In terms of taste, it certainly tastes like pea and has a naturally sweet taste. The sweetness is not too strong, just mild.
