I got it at my local supermarket in the pharmacy aisle, but it's also available on Amazon: https://www.amazon.com/Natural-Vitality-Anti-Stress-Supplement-Raspberry/dp/B00BPUY3W0?th=1
I like Natural Calm for mag. You can also get mag from adding Epsom salt to a bath and soaking for a bit(great for sore muscles).
It's not going to make anything taste better, but it's an excellent supplement and I live on it. However, drop some Calm powder into your water for a tasty electrolytes water. https://www.amazon.com/dp/B00BPUY3W0/ref=cm_sw_r_apan_glt_fabc_D5X9SQX8D05C7RPGX5KD
If you have any motility issues, Nature's Calm. Take care with dosing because it can clean you out!
Otherwise, I recommend Magnesium Glycinate Lysinate:
Okay, so I ended up buying a magnesium citrate/calcium powdered supplement (http://www.amazon.com/gp/product/B00BPUY3W0/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A1P546TAL7E4CV), well a sample version. The recommended dose is 2 heaping teaspoons. I followed suggestions I had seen that said to only take a 1/2 teaspoon at first; I took 1/4 teaspoon yesterday morning with the plan to take another 1/4 at night. I had a pretty loose stool a few hours later but didn't know if it was the supplement or something I ate prior. I forgot to take the other half. So this morning, I took an entire 1/2 so I wouldn't forget, and a few hours later, had really bad diarrhea. There's only like 225mg in 2 full teaspoons, so I'm not sure if I just have to really slowly ease into using it or what. Any thoughts?
Also, will I feel the positive effects of the magnesium immediately or does it take time?
I'm tempted to just buy the magnesium glycinate pills I was originally going to get...
