I agree with swerven, it helps me sleep. It also gives me dreams. For some reason i never had or remembered my dreams, but on ZMA I remember them frequently. And occasionally they are very weird. That might just be me, just thought i'd offer it up.
T-levels are higher in the morning and taper off as the day goes on. But I don't think there are any studies that show a linear type relation with sleep and T, i.e. the more the sleep you get, the more T you have if that's waht you're asking. However, from what I've read, getting too little sleep has been shown to lower T-levels (as does stress and the body treats lack of sleep as a stressor).
But common sense tells you that more, good quality sleep should increase T-levels as, at the end I believe, of each REM cycle your body squirts out some T...
Why someone hasn't done a study on this I don't know. Maybe because the quality of sleep is as important as the amount of time...
I went through a 60 day supply a few months ago just to try it. Frankly, I noticed nothing from it. Everything else is in tact. Diet, workout etc. I didn't even notice the common effect that people mention such as better sleep, dreams etc. Yep, for me it was pretty much like taking a sugar pill, and a complete waste of money.
I just started taking ZMA a week ago and notice a huge difference in sleep. I get to sleep faster and sleep MUCH better. I've gotten up before my alarm more times this week than I have over the last year. I woud like to know if it does raise test levels in non-deficient people. Anyone?
Cy, What about increasing T-levels with supplemention of ZMA within Zinc and/or Magnesium deficient body?
From what I've read many people are in the low range of Zinc who use anti-perspirants. More specifically, the aluminum in many brands of anti-perspirants can block the obsorption of other minerals (like Zinc/Magnesium) from being obsorbed by the body.
Heard anything or seen any studies relating to the topic?
Dude, tell me you have a link or something to the zinc loss theory.
And I've noticed the same sort of sleep enhancement from taking B complex vitamens. Actually when I take a B complex before bed I had sleep heavier than I ever did with ZMA and don't have to worry about not drinking milk before bed like you do with ZMA.
I've heard that Mg is deficient in our diets because it's deficient in our soils from years of farming the same lands. It's not replaced through fertilization to any large extent. Maybe we'd all sleep better and, as a result, dream more just from getting this nutrient.
I was told that the B6 helps with absorption. Zinc can be toxic so you don't want to overdo that one.
