I haven't seen much about ZMA here. I forgot how I found out about it, but apparently it's a supplement popular among bodybuilders, labeled as "nighttime recovery support" that happens to give a lot of people very vivid dreams. For me, it's complete nightmare fuel. When I take it, I feel like I dream three times as much and so I often wake up feeling really disorientated because a forty minute nap feels like a 3 hour dreamfest. I let KestrelKat try one, and she didn't feel any effects (I also remembered that I accidentally gave her half the dosage, though).

The package label says that it contains 30 mg Zinc, 450 mg Magnesium, and 10.5 mg Vitamin B6. While I'm not perfectly versed in my dream supplements, I'm pretty sure that those vitamins tend to have some effects on dreaming. I've tried some other dreaming supplements, most gave me strange dreams or just really really vivid dreams, though ZMA tends to give me nightmares instead, to the point that each time I try it the resulting nightmares usually make me stay away from it for awhile .

Anyone else tried ZMA? Was it helpful for you, or just nightmare fuel?
