Natural Magnesium From The Sea

Isak Dinesen, author of the great book “Out of Africa”, wrote, “The cure for anything is sea water.” Human physiological and environmental circumstances today suggest merit in Dinesen’s advice to look to the sea for replenishment of key minerals.
Magnesium is one of the most important minerals that too many people are neglecting, and a good place to source it – whether in diet or supplement – is from the sea.

Mineral deficiencies can sometimes cause minor problems. But they can also become lethal. Studies show that magnesium deficiency can range from 33% in young people to 60% in adults. This is the result of depletion in the amount of magnesium in the soil, as well as an increase in consumption of processed foods.

Magnesium is required for over 300 metabolic reactions in the body. It’s also nature’s dilator, helping to keep arteries open. This fights hypertension and spasm of coronary arteries. It also has a vital function in maintaining the heart’s normal rhythm. By making platelets more slippery, and therefore less susceptible to blood clotting, the chance of heart attack and stroke decreases.
Each beat of the heart depends on a complex electrical system that must be in sync for survival. Low blood magnesium tosses a monkey wrench into the process causing an irregular heart rate (atrial fibrillation). Adding magnesium often restores the normal beat.

Today, a worldwide epidemic of diabetes creates a huge health problem. Studies show that since magnesium helps to control blood sugar, patients with low magnesium have an increased risk of this disease. And it is a critical mineral for maintaining bone health.
Since magnesium is involved in several hundred metabolic reactions, it’s not surprising that deficiency is associated with muscle weakness and twitching, sleep issues, fatigue and confusion.

But what makes sea-sourced magnesium the perfect magnesium? Sea water has an amazing similarity to the plasma portion of human blood. Although we cannot drink sea water because of its salt content, it does contain the entire range of minerals needed by humans.

This led an Irish company to develop a method of extracting these minerals from clean sea water to make the multi-mineral complex called Aquamin Mg that is low in sodium.

In 1975, he launched his weekly medical column that has been published by national and local Canadian and U.S. newspapers. Today, the readership remains over seven million. His advice contains a solid dose of common sense and he never sits on the fence with controversial issues. He is the author of nine books including, “The Healthy Barmaid”, his autobiography “You’re Going To Do What?”, “What I Learned as a Medical Journalist”, and “90+ How I Got There!” Many years ago, he was successful in a fight to legalize heroin to help ease the pain of terminal cancer patients. His foundation at that time donated $500,000 to establish the Gifford-Jones Professorship in Pain Control and Palliative Care at the University of Toronto Medical School. At 93 years of age he rappelled from the top of Toronto’s City Hall (30 stories) to raise funds for children with a life-threatening disease through the Make-a-Wish Foundation. His hobby is trap shooting. He is married to Susan and has four children and twelve grandchildren.Diana MacKay writes in collaboration with her father under the pen name, Diana Gifford-Jones.
