Most protein powders are SB friendly
Try to aim for ones that are high in protein and low in carbs/sugars. You will find many are sweetened with sucraolose or aspartame (though I would truly try and avoid the latter). New Zealand whey from what I hear is the best- uses Stevia and does not taste bad
Comes in chocolate, vanilla, and unflavoured. Unflavoured is always the healthiest and almost always SB friendly. I am sure whole foods will have a bunch of good choices! Hemp whey protein powder is really healthy too! Good luck!
