So what is wrong with a calcium caseinate, whey iso or albumin? Does anyone even supplement with BCAA's or glutamine?
Calcium caseinate, whey, albumin, ie. milk,milk, egg, ie. dairy, ie. animal products = not vegan. I just stopped using BCAA's and glutamine not because they weren't vegan, just think I don't really need them.
Also I would add, they don't offer anything nutritionnally interesting except for the proteins. Some have calcium, perhaps there's still some vitamins like albumin from white egg (?) but that's it. There's also some studies saying that high quantity of proteins may cause osteoporis. Thing is that some people say that does not happens when it's vegan proteins instead of dairies and other animal proteins."The main problem is the consumption of animal protein; studies have shown that protein from non-animal sources has health benefits. So the answer to preventing osteoporosis is not to consume a lot of dairy products, but to reduce animal protein consumption (...)" http://www.jewishveg.com/schwartz/pcmyths.html"It has been known for nearly 80 y that increasing protein intake increases urinary calcium loss "
"Indeed, a few observational studies reported an adverse association of high protein intakes with bone health (3). However, others found exactly the opposite" http://www.ajcn.org/cgi/content/full/75/4/609
... So we don't know what to believe concerning the possible inconvenients about whey and casein on calcium,
but one thing is sure, it's exploitation of the animals, and can cause other health problems than calcium loss on our health, like higher risks of breast cancers and other cancers.
If we look at cold processed protein isolates like hemp, spirulina, chlorella, there's way more than just proteins, it's some of the foods that contains the highest quantities and largest range of vitamins and minerals on Earth and it's full of benefits for health. Samething with brewer's yeast and other nutritional yeasts, which are over 50% proteins, containing all amino acids.
Even soy isolate, which is processed at high temperatures, is still a source of (depends which brand) calcium, iron, zinc, copper, phosphorus, magnesium, complex B vitamins, it has ability to help lower the cholesterol level, and the isoflavones in it have benefits not only for women but for men too. Studies now show that there's no negative effect from soy on testosterone level.
