Kefir has so many amazing benefits for humans. I drink it everyday and it really does improve digestive system,hair, skin, nails. List goes on. I actually prefer it to yogurt. I give my dogs greek yogurt (stony field because I've heard its the best one to give human babies) They get vanilla and love it. very easy to top off their kibble with. Never any left and they eat what they are supposed to at the same time
For me, I drink the Lifeway Kefir. Lots of flavor choices and I take a supplement called Ultimate Flora - Womens Complete 90 Billion, 12 GPS Probiotic Strains, by Renew Life. Oh to add to that, I do mix in 1 tablespoon of Flaxseed meal. Its ground flaxseed, not just the seeds….I was told by a nutritionist, that the kefir is like to solution that softens everything up, and the flaxseed meal is like the broom that goes thru to sweep it out, lol.
