Hi Everyone,

Since joining this community two years ago, magnesium has been mentioned a few times. I've recently been prescribed diuretics (water pills) and it's my understanding this drug "flushes" out minerals including much needed magnesium. Apart from magnesium rich foods, which is the best magnesium supplement to take? I'm from Australia and assume the brands available here could be different from UK or US. So, any Aussies out there taking mag who can give me a few pointers? Is a magnesium supplement ok if you're hypertensive?

  • Magnesium is usually considered of benefit in hypertension,it relaxes muscles,arteries etc.duretics do flush out minerals from the body. So on balance it's thought to be beneficial but if you have high BP watch the potassium.needs to be in balance.

  • Sorry forgot to say I take mag.oil in form of magnesium chloride.the worse one,it is said, is mag.oxide.hope that helps

  • Thanks muchly - for your reply - will definitely go to Chemist Warehouse -

    always cheap and good for a bargain and check out the potassium/magnesium products.



  • I too live in Australia and my doc has just told me to take blackmores MagMini 500mg 2. A day chemist where house on special $36.95for 250 pills I am on a diuretic also

  • Forgot I also take 1200mg of potassium aday

  • You can get potassium on a script you may need a blood test to see if you are low

  • Understanding Different Types of Magnesium

    Magnesium oxide: Often used in milk of magnesia products since this form has a strong laxative effect. Even though this combination contains a large proportion of magnesium compared to the oxide molecule, it has poor bioavailability and readily causes loose stools; therefore it is considered the least optimal form to use as a supplement.

    Magnesium sulfate: This form is often used as an intravenous preparation but it is not used in oral formulations. Since it does have some absorbability through the skin, it is also found in Epsom bath salts.

    Magnesium citrate: A commonly used form that has a good bioavailability compared to oxide. It is also very rapidly absorbed in the digestive tract but it does have a stool loosening effect.1 This form is found in many supplements and remains a solid option for delivering magnesium into the body.

    Magnesium Aspartate: This form has increased bioavailability compared to oxide and citrate. There were some promising clinical trials conducted in the 1960s that found a combination of magnesium and potassium aspartates had a positive effect on fatigue and they reduced muscle hyper-excitability. Physiologically this makes sense since both magnesium and aspartic acid are critical players in cellular energy production. This form is not commonly found but has been used for chronic fatigue syndrome.

    Magnesium Glycinate: Glycine is a well-known calming amino acid. This combination has good bioavailability and does not have a laxative effect since glycine is actively transported through the intestinal wall. Due to the calming and relaxing effect of both glycine and magnesium, this combination has been used successfully for chronic pain and muscle hyper tonicity.

    Magnesium Malate: This less well-known combination has been studied for use in fibromyalgia. Since malate is a substrate in the cellular energy cycle, it can help improve ATP production; there is some preliminary evidence that it may reduce muscle pain and tender points in fibromyalgia patients.

    Magnesium Orotate: This is another relatively unknown chelate combination containing orotic acid. This form has good bioavailability has had been studied specifically for heart health. Orotates can penetrate cell membranes, enabling the effective delivery of the magnesium ion to the innermost layers of the cellular mitochondria and nucleus. Orotates themselves increase the formation of RNA and DNA which can help heart cells repair and therefore improve function. The combination has been shown to improve heart failure, symptoms of angina and exercise performance in clinical trials.

    Magnesium Taurate: Both magnesium and the amino acid taurine share the ability to improve cardiac function; each has a potentiating effect on insulin sensitivity and also a calming effect on neuromuscular excitability. The actions of both have striking similarities when it comes to cardiovascular health. They both have blood pressure reducing effects, stabilize nerve cells, improve the contraction of the heart muscle and have an anti-thrombotic effect.7 Additionally, low levels of vitamin B6 have been shown to further deplete both magnesium and taurine.

    Magnesium-L-Threonate: This form of magnesium has recently been studied to improve memory and brain function. One preliminary study in animals found that it significantly enhanced both short-term and long-term memory, boosting scores by 15% for short-term memory and 54% for long-term memory compared to magnesium citrate.8 Based on this study, it appears that magnesium-L-threonate is a highly absorbable form of magnesium that can improve brain function. While this research is promising, more is needed to confirm its benefit.

    Magnesium Pidolate (or picolinate): This form of magnesium has generated interest because it is very inexpensive and can easily be made into a liquid supplement. There really have not been any substantial research trials supporting its specific health benefits. The down side of this form is that the pidolate molecule does not have any additional health benefits.

  • Hi dave,

    Thanks so much for your comprehensive reply - a lot to digest (excuse the pun). Thanks



  • Go for the oil. It's not really oil but if you rub it on the skin it absorbs and avoids the gut problems. In Australia you can buy 'Amazing oil' brand from healthfood shops. Bit pricey but lasts for a long time.

  • Thanks Bruce - I like the idea of the oil, I'll look into it - one less thing to swallow. Cheers, Musetta
