CLORURO

Also known as: Magnesium chloride, MgCl₂, MgCl₂ supplement, Cloruro de Magnesio, Magnesium Chloride

Overview

Magnesium chloride is an inorganic salt composed of magnesium and chloride ions, naturally found in seawater and mineral springs. It is primarily used to correct magnesium deficiency, support metabolic functions, and manage conditions linked to low magnesium levels, such as type 2 diabetes, hypertension, and osteoporosis. As a highly bioavailable form of magnesium, it is often administered orally or topically. Research maturity is moderate to high, supported by multiple randomized controlled trials (RCTs) and systematic reviews. These studies indicate its efficacy, particularly in improving glucose metabolism and insulin sensitivity. Magnesium chloride acts as a cofactor for over 300 enzymatic reactions, influencing cardiovascular, neuromuscular, and metabolic systems. It enhances insulin receptor activity and glucose transporter function, making it a valuable supplement for individuals with documented magnesium deficiency.

Benefits

Magnesium chloride supplementation has demonstrated improvements in glucose metabolism, particularly in individuals with prediabetes and low magnesium levels. A 2015 RCT showed that 382 mg/day of magnesium for four months led to improved glucose levels in 50.8% of the treatment group compared to 7% in the placebo group. Systematic reviews also indicate that magnesium supplementation reduces insulin resistance and fasting glucose concentrations in people with magnesium deficiency. Potential benefits extend to managing hypertension, osteoporosis, and migraine, although further research is needed to confirm these effects. The supplement is particularly effective for individuals with type 2 diabetes or prediabetes who have documented magnesium deficiency, with moderate effect sizes observed in improving insulin sensitivity and glucose control at doses around 300-400 mg/day. Benefits are typically observed after 3-4 months of consistent supplementation.

How it works

Magnesium chloride works primarily by providing magnesium, which acts as a cofactor for over 300 enzymatic reactions in the body. These reactions are crucial for glucose metabolism and insulin signaling. Magnesium enhances insulin receptor activity and improves the function of glucose transporters, facilitating the uptake of glucose from the bloodstream into cells. This interaction with the insulin signaling pathway helps to reduce insulin resistance and improve overall glucose control. Additionally, magnesium influences cardiovascular, neuromuscular, and metabolic systems, contributing to its broader health benefits.

Side effects

Magnesium chloride is generally safe when taken within recommended doses. Common side effects, affecting more than 5% of users, include mild gastrointestinal discomfort such as diarrhea and nausea. Uncommon side effects, occurring in 1-5% of users, may involve electrolyte imbalance if overdosed. Rare side effects, affecting less than 1% of users, include hypermagnesemia, particularly in patients with renal impairment. Magnesium chloride may interact with certain antibiotics and diuretics. It is contraindicated in individuals with severe renal impairment, and caution is advised for the elderly and those with kidney disease. It is essential to adhere to recommended dosages to minimize the risk of adverse effects.

Dosage

The minimum effective dose of elemental magnesium from magnesium chloride is approximately 300 mg daily. Optimal dosage ranges from 300-400 mg of elemental magnesium per day. The maximum safe dose from supplements is generally considered to be up to 350 mg of elemental magnesium daily for adults. Magnesium chloride can be taken with meals to reduce gastrointestinal side effects. It is preferred for better absorption compared to some other magnesium salts. Avoid concurrent high-dose calcium or zinc, which may compete for absorption. Adequate vitamin D and calcium status may enhance magnesium utilization.

FAQs

Is magnesium chloride safe for long-term use?

Yes, magnesium chloride is generally safe for long-term use within recommended doses, provided kidney function is monitored regularly.

How soon will I see benefits from magnesium chloride supplementation?

Typically, benefits such as improved glucose control and reduced insulin resistance are observed within 3-4 months of consistent use.

Can magnesium chloride help with diabetes?

Magnesium chloride may improve glucose control in magnesium-deficient individuals with prediabetes or type 2 diabetes by enhancing insulin sensitivity.

Is magnesium chloride better than other magnesium forms?

Magnesium chloride generally has higher bioavailability compared to some other forms of magnesium, such as magnesium oxide, leading to better absorption.
