whats the difference in all the magnesium? citrate, chelated, oxide, etc?
A shopper

Best Answer:  Oxide best/easiest form to absorb.

Does the above vitamin magnesium oxide supplement the deficiency of magnesium mineral ?
A shopper
how does this mag compare with the Blaine mag-ox400? i take two a day of the blaine mag-ox 400 brand an need something comparable an alittle more cost friendly .
g j.
How is magnesium oxide different from iron oxide in that there is no carbon atom biologically bound to the mineral? This is simply an oxidized form of the metal, and since humans can't photosynthesize inorganic minerals to make them biologically available as can plants, then how is this any different from eating a handful of dirt?
Elbridge S
Will Magnesium Oxide help with Constipation?
Darlene M

  NO!! Magnesium Oxide makes it worse. Choose magnesium clelate or magnesium glycinate instead.

Suzanne

  I don't think so. Try Calm it is pure magnesium the raspberry,Lemon is good.

Elaine W

  I am not sure about that, I take Magnesium for general health. However, if you do not take Psyllium Husks powder daily, you should. Most people do not get enough fiber intake and this will help. Be sure to follow it up with a full glass of water.Available at Vitamin ShoppePsyllium Husks Powder12 Ounces Powder Item #: VS-1654 / 1312594

Is the capsule kosher? The Gelatin surrounding??
allison q

  I don't believe so. It does not carry the kosher symbol.

Ashley D

On the ingredients it says it contains gelatin, which is made from pork products. I look for a kosher label, or bovine gelatin or vegetarian gel caps.

Jayna N

  Sorry, I don't know.

Is this product similar to the product "Oxy Powder" capsules?
Jeanne P

  We use this product to give oxygen to your digestive system, this keeps things moving in your digestive track without side effects. I love this product, I kept being told I had IBS and have had stomach problems forever, I stooped dairy and use this, amazing results

Lisa H

  Jeanne P, I think magnesium oxide is NOT similar to Oxy Powder. Oxy Powder is a combination of magnesium oxide, magnesium hydroxide, and magnesium peroxide, 2 of which were 'ozonated' to assist in oxygen formation & transport through the colon for a 'colon cleanse'. It contains 1537mg of elemental magnesium, 384% DV. It is important to understand why you are taking a supplement. If a colon cleanse is what you're looking for, I suggest you review meaningful research and medical recommendations. If constipation is the issue, there are many OTC options that are effective and affordable. I purchased Magnesium Oxide to supplement a low magnesium serum blood level caused by long-term use of an antacid. I hope this helps you in your decision making process.

How big are these pills and are they easy to swallow for someone who has difficulty swallowing bigger pills?
A shopper

  I also have trouble swallowing large pills and am very careful about the size of pills I buy. This Magnesium Oxide comes in capsule form, which is what I buy. Since they are the size of your average capsule, they are very easy to swallow.

Ann B

  MgO capsules are gelatin and half the size of fish oil capsules. They are easy for me to swallow.

Steven H

When is the best time to take Magnesium oxide?
ABDUL

  I take mine at bedtime to help me relax and sleep and then it helps with the morning BM slso

Wendy K

  I take one Magnesium Oxide capsule with breakfast/brunch. This product has significantly reduced the leg cramps I was experiencing four years ago.

Michael

  I don’t know about the best time, but I like to take it at night. It makes me sleepy and sometimes causes some intestinal issues.

Magnesium Oxide 400 MG (200 Capsules)

Magnesium oxide helps to support heart and muscle health. This mineral also promotes normal cell function, robust nerve responses, and strong bones. Although magnesium is found in foods like beans, nuts, and green, leafy vegetables, many people's bodies – due to diet, stress or other factors – may prevent them from accessing or using enough of this essential mineral.

While magnesium is readily available in many foods, only 30 to 40 percent of dietary magnesium that people consume is usually absorbed by the body, according to the National Institutes of Health (NIH). Some foods and substances, like soda and alcohol, can limit magnesium absorption, either by rendering it unusable for your system or by causing rapid excretion. Stress, certain medications, and some chronic diseases can also reduce magnesium absorption in the body. People who suffer from magnesium deficiency may feel its effects every day through muscle cramps, chronic pain, and fatigue.

The NIH's Recommended Daily Allowance (RDA) of magnesium for adult men is between 400 and 420 mg of magnesium each day on average. The RDA for adult women is between 310 and 320 mg daily. Because magnesium is essential for normal bodily functions, you might be considering magnesium oxide capsules to get enough of it. Magnesium oxide capsules with 400 mg of this essential nutrient to help keep your heart, nerves, bones, and other systems function properly.
