ZMA and calcium


#1

Is it the zinc or the magnesium that doesn't absorb well with calcium? My brother is taking a magnesium/calcium supplement and I could have sworn that those two don't do well together.


#2

It's the zinc.


#3

Calcium binds with magnesium. Take calcium in the morning and ZMA at night.


#4

Both are contraindicated with calcium. a cal/mag supplement will usually see calcium winning that battle. look for magnesium citrate without calcium, but also check under other ingredients since most companies use dicalcium phosphate as a filler for the tablets


#5

Actually, after re-reading the T-Mag interview with Victor Conte, calcium interferes with BOTH zinc and magnesium absorption. Hope this helps.

Thanks guys, I actually (with furhter searching) found the info by Victor Conte and answered my brother's question. He's not a body builder, more like a half hearted health enthusiast (is that an oxymoron?). He is confused about health and is swayed by infomercials (bought the electrical stimulation ab thingy)and his favorite protein? You guessed it - soy. He wants to look perfect, but doesn't want to work for it. I guess all in all he's an average american. Maybe some day he'll take all my advice instead of picking and choosing.
