I take the Kre-Alkalyn from EFX, 2 pills in AM, 2 pills in PM. Got a 400 pill canister on Amazon for 39.99 (Prime).
Will last 3+ months. when I buy the powder, I always end up forgetting. Keeping this canister on m y desk, I never forget.
Lots of studies say one isn't better than the other, some say just do monohydrate, whatever, I like t his stuff so it works for me...
