When I first had surgery, whey protein was kind of the "gold standard" for protein powders. It was called a "predigested" protein, which was easier for my altered stomach to digest. At Ellen's suggestion, I switched to a grass fed beef protein powder. No, it doesn't taste like beef. I use vanilla, and I find it to be a much higher quality protein. I tried to go back to whey (as it is cheaper than my new protein powder), but I could taste the fake sugar in the whey. You get what you pay for. So I am sold on this one.
A year or so ago, I started adding a collagen protein to my shake. I felt like it would be good for my hair and nails. It has no taste.
I take my probiotics religiously. I take one that I get through Ellen. I also drink a kefir tea every other day. When I am in a bind, I do like this brand (in fact, if you ever have to take an antibiotic, they have a five day super strong version that I take to replenish the good bacteria; you can find it in the fridge at places like Whole Foods):
I also take fish oil. I don't eat fish but I know its good for your brain. Ellen had me switch to fermented cod liver oil. It also helps with inflammation.
Anyway, these are just a few of my favorite supplements (I also take a simple biotin for my hair and nails). Working with Ellen on my health and making supplements like these a priority have helped me feel better than I have in years. At 41, I feel better than I did in my 30's!
