Rated 1 out of 5 by from HORRIBLE taste! This liquid mag is absolutely VILE tasting. I could not disguise it no matter what I put it in. I do not recommend. Better to go with a powder like mag glycinate (great to add to Swanson's chocolate whey protein powder). Utterly hideous.

Rated 5 out of 5 by from Makes your water taste like Evian If you like Evian bottled water, try 3-4 drops of this in your glass. I filter my water, and adding this softens it and gives it a smooth taste. I know you're supposed to use more to get enough magnesium to be beneficial, but I take supplements for that. I use this just for the taste. This is also a good way to get more boron.

Rated 5 out of 5 by from Adds minerals to my water I buy pure water and add these minerals to my water and love it. Nice taste for me. I don't use too much but drink it throughout the day. Helpful to get the needed minerals in my clean water.

Rated 5 out of 5 by from Best trace mineral supplement This is a great product. I have been using it for 6 months now. A few drops a day take away cravings and I have so much energy. Convenient to put in your purse and add a few drops to your water at joke or the restaurant. I used to buy it at my local wholefoods but the price is much cheaper here so I get 2-3 bottles at once

Rated 5 out of 5 by from Magnesium Before I started putting other supplements into our smoothies, I started using Mega Mag. There are many processes in the body dependent on magnesium. Certain foods and medications may block or deplete magnesium and other nutrients. Our energy is through the roof and we sleep better. I think this is the most important mineral and hope people look up magnesium deficiency to find out why. I find this product to have the best absoprtion. It should be mixed with water, juice, or smoothies to be palatable.
