Marine magnesium is popular at the moment. It is a mixture of inorganic salts that offers good magnesium content although absorption is poor.

Magnesium is absorbed principally in the small intestine, through a saturable transport system and via passive diffusion through bulk flow of water. Absorption of magnesium depends on the amount ingested. When the dietary content of magnesium is typical, approximately 30-40% is absorbed.

Conclusions: Our data support that magnesium derived from a marine-derived multimineral product is bioavailable to a significantly greater degree than MgO and displays a similar profile to the more bioavailable MgCl2 and may offer additional health benefits given its multimineral profile.

Therefore, our Marine Magnesium is a pure ocean-sourced, natural form of magnesium hydroxide containing a minimum of 35% magnesium derived from clean waters off the Irish Coast. Marine Magnesium is precipitated from seawater. Seawater contains approximately 3.5% dissolved salts of which about 0.5% is soluble magnesium.

Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.

Tips for improving magnesium absorption

1. reducing or avoiding calcium-rich foods two hours before or after eating magnesium-rich foods.
2. avoiding high-dose zinc supplements.
3. treating vitamin D deficiency.
4. eating raw vegetables instead of cooking them.
5. quitting smoking.

Prebiotics help absorption of Magnesium. Also Iodine and Calcium. Also organic salts are better absorbed.

It is an essential component of DNA and is necessary for over 300 metabolic reactions in the body, It helps maintain normal nerve and muscle function, normal heart rhythm, normal neuromuscular conduction, normal blood pressure, and maintains bone integrity as well as glucose and insulin metabolism.

Magnesium glycinate — Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea. It is the safest option for correcting a long-term deficiency.

Tips for improving magnesium absorption People wanting to increase their magnesium levels by improving absorption could try: reducing or avoiding calcium-rich foods two hours before or after eating magnesium-rich foods. avoiding high-dose zinc supplements. treating vitamin D deficiency.

Moreover, these three sources of magnesium have significantly greater bioavailability than MgO [7]. Magnesium derived from magnesium hydroxide (Mg(OH)2) (Mablet) has been shown to be absorbed into the circulation and, hence, bioavailable in healthy male adults [8].

Aquamin-Mg is a natural source of magnesium, containing 72 additional trace minerals derived from the clean waters off the Irish coast. However, the in vitro bioaccessibility and bioavailability of Aquamin-Mg in comparison with other supplement sources of magnesium has yet to be tested.

Mineral absorption is normally proportional to dietary intake, with two important distinctions—the absorption of iron and calcium, both of which can be regulated according to the needs of the body. Calcium absorption is related to the amount of specific binding protein within the enterocyte.

However, in patients with conventional ileostomy, inulin and oligofructose effects on mineral absorption and excretion (Mg, Zn, Ca, and Fe) showed no significant influence (Ellegård et al., 1997). Similarly]
