Relaxes nerves and muscles and supports relaxation and restful sleep.* Completely soluble in water-based liquids and contains citric acid, therefore it is also buffered when in solution. This powder dissolves in water, juice, lemonade or any other waterbased liquid. It is non-gritty and has a very pleasant citrus taste that comes from the citric acid present. Magnesium citrate tends to loosen stools.* Hypoallergenic. Gluten and casein free. Ultra Tested®.

Magnesium is an essential mineral that is involved in many body functions as well as being a constituent of bones and teeth.* It is an essential element of cellular metabolism and is an enzyme activator.*

Other body actions include:

• relaxing nerve impulses and muscle contractions;
• supporting relaxation and contributing to restful sleep.*

Signs and symptoms of magnesium deficiency can include fatigue, mental confusion, irritability, weakness, muscle spasms, loss of appetite, difficulty sleeping or a feeling of weakness. The Physician’s Desk Reference for Nutritional Supplements states that recent data of inpatient and outpatient populations suggests that magnesium deficits may exist in 12% to 40% of individuals.

There are many different forms of magnesium, and no compelling data about absorption differences. However, there are reported differences in how different forms affect the gastrointestinal tract.* Forms and functions of some of these include:

• oxide: tends to firm stools in some individuals and loosen stools in others,*
• glycinate: a very gentle form of magnesium that is easier on the system,*
• citrate: tends to loosen stools,*
• sulfate: tends to loosen stools*
• chloride: tends to loosen stools.*

Individual results may vary. Your physician should recommend the form that’s right for you.

Magnesium supplements usually have their beginning as minerals that have been influenced by our environment. For that reason, the purity of magnesium raw materials is important. Magnesium, like calcium, can have undesirable impurities present. Kirkman’s magnesium is Ultra Tested®, which means it is tested for more than 950 environmental contaminants, the highest standard of purity testing in the world.

SOLUBLE magnesium citrate

Unlike most of the other magnesium citrate, this one is soluble. With all of the liquid magnesium citrates off the market now, I use this as a substitute for my 99 year old mother. She says it works just fine. More expensive than the bottled magnesium citrate, it is a good substitute.

WOW...I'm impressed

This is super! If you need an immune boost, then this is it. I've been taking this stuff for about two years now and have not been sick once. I feel better and I believe that it truly does help keep my immune system at its best. Hey, at 73, I need the extra help!

Wish it was complete

This is one of the better brands with regards to bioavailability and supporting MHTFR. I definitely notice a difference in energy. Clean energy, not jittery. The only complaint is that it is not a complete B complex. I dont understand why they didnt add all the B vitamins to this formula. Ive read a lot of articles that say its important to balance out our B vitamin intake. In other words, if you are taking one B vitamin, you should take them all. That they play on each other, that one needs the other to function properly. This formula is missing Thiamine, and Niacin. Two B vitamins that a lot of important benefits. Im curious as to why Thorne omitted these two vitamins. I took these for a year thinking they were complete. I started to feel sluggish again and thats when I researched and found a lot info on balancing out B vitamins. Ive since added Thiamine (AllThiamine version) and Niacin, and feel better, a little more energy than I had before. Again great brand, love the high dose, and added TMG, just wish it was more complete B complex.
