  • The magnesium for energy

  • Essential nutrient for over 300 enzymatic processes*

  • Bound with aspartic acid for energy support

Magnesium is essential for over 300 enzymatic processes, not the least of which involves energy production.* Aspartic acid is also a critical component of energy production at the cellular level.* Scientists have found that binding magnesium to aspartic acid produces an effective magnesium supplement with additional energy support not offered by other forms. Swanson Magnesium Aspartate is a great alternative for those concerned about muscle fatigue and neuromuscular health.*

Rated 5 out of 5 by from Great! Best magnesium supplement I have ever used. I have tried Magnesium Oxide in stores but it never seemed to help. I also tried Swanson brand Magnesium Citrate Powder and it worked really well but I did not want to taste it. This was the best solution. I actually feel relaxed after I take these in the evening.

Rated 5 out of 5 by from Best Purchase Magnesium really helps me to sleep. I take this formula along with the Swanson orotate formula for almost 200 mg of easy to digest elemental magnesium.

Rated 4 out of 5 by from Labeling confusing I thought I was ordering 685mg of magnesium, turns out there are only 133mg of magnesium. So I reordered another kind, I thought, thinking this one for sure was at least 600 mg of magnesium. But apparently I didn't read it carefully when I was ordering, and ended up with the same thing again! Well, I do have to say it defintely works if I take 4 a day, for bowel hydration, but next time, unless I get more information, I will order another product, because 90 caps won't last me a month taking them 4 a day. By the way, you didn't have a category that really fit me for how I am motivated...I am motivated to shop Swanson's because the quality is high for the price which is usually excellent compared to other online suppliers.

Rated 5 out of 5 by from Great Value Best deal I've found for Magnesium Aspartate. Regular price is 1/3 of what I had been paying, and the current BOGO makes it a real steal! Couldn't be happier with the price and effectiveness!

Rated 4 out of 5 by from Aspartate is form of aspartame Aspartate is form of aspartame and breaks down to formaldehyde, so best avoided.

Rated 3 out of 5 by from Works okay The product seems to work okay, but I don't like having to take three pills to meet the RDA. The price is very reasonable, however. I found that the Magnesium Glycinate has about the same bioavailability, and seems to bother my stomach less. I will switch back the Kal Brand Magnesium Glycinate (two pills to meet the RDA). It is a bit more expensive though.

Rated 5 out of 5 by from Best magnesium Have used many different magnesium supplements over the years, and for some reason the aspartate form works the best for me. And as usual, Swanson gives excellent value.
