      Good Bleng Magnesium

      from NC on 3/01/2022
      Good Magnesium. The types blended here are the types of Mag I like to take. Finally companies are combining more than 1 type of magnesium in one pill. Also, not too strong, so if I want a lesser dosage 1 day, I can just take one. Source Naturals is a dependable brand, and PF delivered fast, at a good price.

      Ultra Mag by Source Naturals

      from Brecksville OH on 1/14/2020
      The formulation of multiple forms of magnesium is fantastic. Not too many like this on the market. I take it at bedtime to relax me and help with sleep.


      Well formulated and very affordable.


      Source Naturals almost always adds magnesium stearate,a cheap additive that is not healthiest. I wish they would leave this ingredient out. Otherwise, I'd give this 5 stars.

      I feel my feet again!

      from VAUGHN WA on 5/27/2018
      It hasn't been that long that I started Ultra-Mag by Source Naturals for Diabetic neuropathy and I can feel my feet already!


      It's working! And I only have to take two tablets a day to get all the types of magnesium that I need.

      Best mag supplement on the market!

      from iowa on 5/02/2016
      I use Ultra Mag Hi Efficiency by Source Naturals to help with the bad side effects of adderall. I usually take it at the end of the day, but I know people take it an hour before or after their adderall to increase effectiveness. Also, it has multiple forms of magnesium, and also has vitamin b in it which is always a plus.


      I trust this brand. I also use their dopa mucana and I have noticed better quality than NOW vitamins.


      It's kind of big but you get used to it.

    • I can feel the difference.

      from MI on 7/23/2015
      I use Ultra- Mag Hi Efficieniency by Source Naturals each night to help with sleep and to calm. I used to get joint aches at night, which are no longer an issue with adequate mag. I recently tried an OTC brand of mag, which is no where near as effective, and I found myself increasing the dose to get the same results. This is a good product at a good price!

      Good combo of various types of magnesium

      from Connecticut on 7/12/2015
      Ultra-Mag Hi Efficiency Mag by Source Naturals is the best combination of different types of magnesium I've found. It's hard to know which type to best, so might as well get several all in one supplement.


      Several forms of magnesium.


      Wish it was in capsule form.
