I've tried several forms of magnesium, including citrate, carbonate, oxide and oratate. None of the forms I tried had any affect. I have muscle twitches, tightness and trouble sleeping and had read several studies showing that magnesium appears to help with these issues, yet none of the forms I tried had any noticeable affect. Then I saw the Now aspartate form, but read many people saying not to use aspartate form because aspartate is an excitatory amino acid that overexcites brain cells. I almost didn't buy it after reading people putting the aspartate form on their "worst types of magnesium" list but since I had tried so many other types to now avail, I figured I'd just go ahead and try this form and boy am I glad I did! I opened two capsules and sprinkled them in my drink mix. I wanted to make a homemade electrolyte drink because these muscle cramps had gotten so bad, especially at night. I used the True Lemon Raspberry Lemonade powder packet because it has no artificial sweeteners or artificial colors, just stevia and 1 gram of sugar and is only 10 calories. I shook up it and it tasted great. I drank it right before bed and even before I finished the 16 ounce homemade electrolyte drink I could feel the muscles in my neck and shoulders relaxing, then I felt myself getting drowsy, then before I knew it I fell soundly asleep. I sleep through the entire night, which I haven't done in years. I usually toss and turn and wake up several times and have trouble both getting to sleep and staying asleep. I awoke refreshed, which also never happens. And I had zero leg, or foot cramps during the night, which hasn't happened in at least 5 years! Tonight as I sit here and type this I have made an electrolyte drink and am drinking it as I'm getting ready for bed and I can feel it working already. I can feel my muscles relaxing. I also had more energy today due to the magnesium I had last night. AND I also didn't have frequent urination. I normally wake up two or three times in the middle of the night to pee and I didn't wake up once! That was a totally unexpected benefit so I checked PubMed for some research studies and found that low magnesium can cause frequent urination. Wow. And for like the last 6 months I'd seen my doctor about frequent urination and all he did was try to get me to take some kind of pill to slow my bladder but I did not want to take medication, I wanted to find out what was causing the frequent urination and now I know! My magnesium was too low! I plan to drink this each night before bed (I hear that's the best time to take it if you have muscle cramps, stiffness, trouble sleeping etc). This form of magnesium has been a miracle already so I don't care what anyone says, the aspartate form is going on my BEST form of magnesium list! The proof is in the pudding! I've used the Now brand of products for over a decade and they haven't let me down yet! Their products always seem to work when others don't.!

Item received was exactly as expected. While &#34;Now&#34; products aren't usually my preferred in regards to branding, they have a great price/quality ratio and are widely available.<br /><br />I bought these in order to help with the grinding of my teeth, and found that the Magnesium Aspartate helped me tremendously. I had tried out other products, and other types of magnesium, but didn't find them to help that much and in reality they were quite lacking. I finally just got used to using a mouth guard, until I was recommended these. Now that I know they work, I plan to keep using them.<br /><br />In summary, if you have issues with bruxism or grinding of your teeth, this is the supplement to get! It's a total game changer!

I use this product for a racing heart, as it works to slow down the rate, it works better than any medications. No problems since I have been using it.

For an unknown reason, I get gnarly a Charley horse in my right calf which refuses to go away. These help greatly, and I take no less than one a day now, and an extra if the muscle cramp returns. Strongly recommend.

My left forearm was plagued by intermittent muscle twitching. I could be holding my phone and it would pitch sideways. The twitching would pulse several times a minute at nighttime keeping me awake. My doctor told me to take some potassium. I tried eating more bananas but that did not help. Since taking this Magnesium and Potassium supplement the occurrence of my forearm twitching has been reduced by about 98%. The few times it does occur, the twitching is much more mild. I am very pleased with this product.

This is great stuff. I was using another brand of magnesium & potassium aspartate to help with bowel elimination but it wasn't working well enough. Then the other brand ran out and there was a problem with the manufacturer so I tried this one and it worked even better. The only difference between both of them was the taurine.
