From the Guidelines

Aquamin Magnesium is a natural, highly bioavailable magnesium supplement that can be used to support various bodily functions, with typical dosages ranging from 300-400mg daily. When considering the use of Aquamin Magnesium, it's essential to prioritize its potential benefits and risks, particularly in the context of morbidity, mortality, and quality of life. According to a recent study published in the Mayo Clinic Proceedings 1, magnesium has been used in the treatment of erythromelalgia due to its calcium channel blocking properties, which can lead to vasodilation. The study suggests that magnesium treatment should be initiated at the recommended daily allowance and increased gradually to minimize potential side effects such as gastrointestinal intolerance, muscle weakness, and hypotension.

Some key points to consider when using Aquamin Magnesium include:

  • Typical dosages range from 300-400mg daily, though this can vary based on individual needs and product formulations
  • It is commonly used to support bone health, muscle function, and nervous system health
  • Magnesium is essential for over 300 biochemical reactions in the body and may help with muscle cramps, sleep quality, and stress management
  • The natural origin of this supplement means it contains a complex of additional trace minerals that work synergistically with magnesium, potentially enhancing its effectiveness

It's also important to be aware of the potential risks of magnesium toxicity, as highlighted in a study published in Circulation 1. Patients with magnesium toxicity can present with cardiac effects, neurological effects, and other signs such as gastrointestinal symptoms and skin changes. However, this risk can be minimized by following the recommended dosages and being aware of individual factors that may increase the risk of toxicity, such as renal failure and metabolic derangements. Overall, Aquamin Magnesium can be a valuable supplement when used appropriately and with caution.

From the Research

What is Aquamin Magnesium

  • Aquamin-Mg is a natural source of magnesium, containing 72 additional trace minerals derived from the clean waters off the Irish coast 2.
  • It is a marine-derived multimineral product that is bioavailable to a significantly greater degree than magnesium oxide (MgO) and displays a similar profile to the more bioavailable magnesium chloride (MgCl₂) 2.
  • Aquamin is also rich in calcium and 72 other trace minerals, and has been shown to promote increased mineralisation in osteoblast cell culture, suggesting a potential role in promoting bone formation and treating bone diseases such as osteoporosis 3.

Health Benefits

  • Magnesium, the primary component of Aquamin-Mg, plays a key role in maintaining normal cellular physiology and metabolism, and has been associated with a reduced risk of cardiovascular disease, osteoporosis, and other chronic diseases 4, 5, 6.
  • Aquamin-Mg may offer additional health benefits due to its multimineral profile, including the promotion of bone health and the prevention of diseases associated with magnesium deficiency 3, 5.

Bioavailability and Absorption

  • The bioavailability of Aquamin-Mg has been tested in vitro using the Caco-2 cell model, and has been shown to be comparable to that of magnesium chloride (MgCl₂) 2.
  • The absorption of magnesium from Aquamin-Mg is greater than that from magnesium oxide (MgO), suggesting that it may be a more effective supplement for individuals with magnesium deficiency or insufficiency 2.
