GO MAGNESIUM 1-A-DAY is a high strength, 1-A-Day formula which contains 500mg of elemental Magnesium per capsule. 

Sourced from seawater, this natural marine Magnesium contains no Magnesium oxide, giving it superior absorption as well as being gentle on the digestive tract. Magnesium is effective in supporting relaxation, soothing muscle tension and muscle tightness as well as for supporting a good night’s sleep.

Magnesium is one of the most important nutrients as it is involved with hundreds of processes within the body but is easily depleted when the body is under stress from things such as exercise, stressful situations, poor diet and alcohol or just from having a modern busy lifestyle.

GO Magnesium 1-A-Day is a great way of ensuring you get your recommended daily intake of this vital mineral to help keep operating at your best.

  • 1-A-Day dose per capsule

Helps me sleep Review by
  • star

Take these religiously helps me feel sleepy and keeps cramps away

No more cramps Review by
  • star

Great for preventing night cramps in my legs. Have not noticed much improvement in my sleep quality, but that is probably due to a variety of factors. Good value for money.

Great product Review by
  • star

I used to get a bit of cramp in my calf in the morning but after taking the magnesium I havent had any problems. I dont have a problem with the size of the capsule as other people have. I just take it with water. Easy to swallow.

Magnesium caps Review by
  • star

Having fibromyalgia and therefore lacking in magnesium these capsules help me rest at night. Also having a history of being constipated they also deal with that problem each morning. They are also extremely good value for money.

capsules are too big Review by
  • star

The size of the capsule makes them impossible to swallow, I have been opening mine and pouring them into milk to take them. There is no way i could swallow it they are like horse pills. Maybe make them smaller and two a day for this one eh Go Healthy? Otherwise I have always been very happy with every product i have bought from this company.

I really love this product. I have had problems with my bowels for a number of years and this along with milk thistle has made a huge difference. I am now going regularly and without pain. This has also helped with my muscle tension and with sleeping. A great overall product.

Already feeling the benefit of this product Review by

I've suffered with Atrial Fibrillation for most of my life. I was first diagnosed with AF in my early twenty's. Probably caused by handling organo-phosphate sheep dipping chemicals for a number of years in a chemical application business I started after leaving school in 1967. The erratic heart beat gradually worsened to the point I had to get out of the NZ agricultural spraying business in the 70s.

Despite not handling chemicals after moving to Australia, the AF continued to get worse. It culminated a few years ago with me having heart failure which resulted in complete organ failure (heart liver and kidneys) and with an emergency flight from Cairns by the Royal Australian Flying Doctor Service to QLD Brisbane - Prince Charles Hospital, where I was put on life support and remained in a coma for seven days.

To cut a long story short I have never found anything natural that would help stabilise my dangerously erratic heart beat. I had resigned myself to taking ever increasing levels of beta blockers and digoxin to control the symptoms. It wasn't until recently I read about magnesium and how essential it was in the body and especially for the function of the heart.

Unfortunately there is a lot of mis-information when it comes to the bio-availability of magnesium and how it is made. I started with a popular brand that was recommended to me based on magnesium aspartate which is meant to be easily absorbed. Although I felt an improvement in the first few days it was short lived. Research showed me that magnesium aspartate is a compromise because it is cheap to make and can convert in the liver to MSG (mono sodium glutamate). Guess what? One of the triggers for my AF is MSG and I started feeling much worse after a week with a noticeable feeling of inflammation in my liver. I quickly ditched the Magnesium Aspartate and found a more natural source of magnesium with Go Healthy derived from seawater. It contains other essential minerals which are needed by the body which is a big plus.

It's only been a few days, but already I have cut down on the beta blockers and cut the digoxin in half. Blood pressure is fine 116/60 and heart rate although still too fast at 80 bpm is better than when taking the full rate of digoxin. I'll be keeping careful note of how I feel and watching my BP and heart rate over the next few weeks. I have heard of people actually making a full recovery from debilitating AF without needing Cardiac Ablation, which was the next step for me. Hopefully I can add another positive review in a months time so others can learn from my experience.

I have a very long term old friend using this product for some time and he, at 90 years old, is sleeping better, less shaking and obviously walking and doing his normal day to day activities better than I have seen him do for months. He is still driving and is very mentally alert. He has a renewed vigour for life and is still going out floundering in his boat and setting his nets. Not many people people at 90 would be capable of that!

The service and the price from Health Post is second to none anywhere in the world. Well done you guys! I paid less than half the price I saw this product on the shelf for in a local chemist and I had free delivery. The added bonus of buying online is the fact you can research the product completely without the pressure to buy when you are in a shop with an assistant standing next to the cash register waiting to make a sale.
