Yes, exactly those. I forget where I read that they were adequate, but I do recall that the citrates were not available at my favorite shop. I should probably look into it again, I've been going like this for about three years. I mean, I feel good and cramps are not happening, and my blood work is good, but it never hurts to try something else now and then.
Well, unless I get cramps again. Those suckers really hurt.
