I don't use protein powder or have any kind of special diet. My reasons for taking this was to replenish some nutrients after ceasing to take a medication (bupropion) that may deplete glutathione and nutrients. My laypersons research told me that pill-form glutathione and amino acids aren't useful, and whey is the best option for getting certain amino acids.I've only taken this a handful of times. So far I can tell that at least it's not offensive (not yummy either)-- it has a powdered-milk taste and smell but more mild. I mix it with water, it's also not harsh on my stomach and oddly seems to satiate my appetite.If I were supplementing for athletic reasons, or trying to diet, or living in a place with poor food options, this is the powder I'd use. It clearly has a high nutritional value. The ingredients are processed with integrity so that the beneficial amino acids and protein will reach the body.There have already been a number of reviews on exercise and fitness use of this, but I have one other use to add.I have been in a travel situation in the past where the food options were very poor. I tend to be on the skinny side, even more so then as I was young. I remember some similar, natural whey powder that my sister sent me with. I started using it after a month in the poor-food situation, and my entire body felt much better almost instantly. I can't remember what brand that powder was, but I use the anecdote just to point out that a high-quality whey powder like this one is a great option for people who don't otherwise have great nutrition options. I haven't put this specific powder to that specific test, though. But it seems like a very high-quality whey powder from the ingredients and process method and how easily it seems to be on the stomach.So far so good. It's probably too early for me to notice any health effects.
