I bought the last two bottles from desertcart because it saves me a lot of money and a trip to the store (even though it’s “local” it’s not close to home and they are usually closed when I’m in that area). Anyhow, the owner is extremely knowledgeable with natural supplements for overall health as well as specific health problems, so after telling him about some of my husband’s symptoms at the time, he recommended these magnesium pills. Because there are so many different factors involved, including other supplements he is taking, I can’t say with total certainty that these have made a difference, but I am pretty sure they have helped him with at least three problems. They are pretty big pills but he has no trouble swallowing them. So the bottom line is that based on tons of articles by the experts and research and studies on how much our bodies need magnesium for so many different reasons, we know that we should be taking magnesium supplement unless we are able to get enough in our diet (which we don’t since we live like most Americans who don’t have fresh vegetables prepared and ready to eat everyday lol!), and yes I should probably start taking them too… and yet not all magnesium supplements are the same. So getting one that has multiple forms of magnesium like this one is certainly a smart choice, and since it was recommended by someone I have known and trusted for years I feel it’s a smart choice for us. Review: Excellent quality, helps calm me down with anxiety and helps my muscle pain. - This magnesium blend is awesome! It has malate and glycinate, two of the most absorb-able forms. The price was amazing and I trust this brand. The only downfall is the size can be a problem if it's hard for you to swallow pills in general. I did just fine and I think the benefits far outweigh swallowing an odd shaped pill once a day. I am better with keeping calm and anxiety in general. This blend is great for anyone with fibromyalgia and chronic pain- it's been a help, less muscle cramping. Overall awesome product at a great buy. ## Features - ULTRA-MAG features a high potency of bioavailable magnesium from five sources, plus vitamin B-6 to support magnesium utilization and optimize its benefits - This essential mineral is also necessary for activating over 300 metabolic enzymes, and powers the health of the heart, bones, brain, muscles, liver, and kidneys.* - Suggested Use: 1 or 2 tablets daily with a meal. - Over 40 Years of Trust.

How much elemental magnesium per tablet? What are the ingredients?** A: Got a bottle right here. Back says: Magnesium citrate, malate, glycinate, and succinate. 400 mg total (doesn't say amount for each compound). Also contains pyridoxine hcl (b6) at 50 mg and sodium at 5mg. Other ingredients: stearic acid, acacia gum, modified cellulose gum, magnesium stearate and silica. **Q: Why so much B6 in this formula?** A: Magnesium supplements are sometimes taken at the same time as the vitamin B6 supplements to counteract the side effects of the vitamin B6. **Q: don't understand the 400 mg when the back of the bottle each tablet contains 120 mg of the contents per serving; that equates to 240 mg for 2 tabs?** A: My labels (on various size bottles) all say “400 mg per serving” and “Serving size 2 tablets”. That means each tablet contains 200 mg of magnesium. I take 3 tablets every day to equal the 1:1 ratio for calcium and magnesium that’s recommended. You might be looking at a description of how many tablets are in the bottle. (See the illustration at left. It says, as I did, “400 mg.... Magnesium Complex”.) **Q: Are these hard or easy to swallow?** A: The pills are elongated “ovals” and yes, fairly large, but in spite of the fact that I have a hair-trigger gag reflex, I’ve never had a problem swallowing them. I take one of these three times a day (600 mg to balance 600 mg calcium). I favor this form of Mg++ because it’s chelated (attached) to several amino acids that are normally part of our metabolism, and importantly, because magnesium is a laxative, this form causes NO digestive problems. If taking the pill just with liquid doesn’t work well for you, try taking it with a warm liquid (coffee or tea) or something slippery, like jello. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A smart choice for us. *by R***N on September 18, 2016* I have been getting these for quite a while now for my husband mainly, after our local health food store owner recommended them.
