Seawater

Also known as: Deep Seawater, Mineral-rich Seawater, Ocean Mineral Extracts, Deep Seawater Extracts

Overview

Deep seawater extracts are sourced from the deep layers of the ocean, characterized by high concentrations of essential minerals like magnesium, calcium, and potassium. These extracts serve as dietary supplements, primarily aimed at improving mineral intake for individuals with deficiencies, promoting metabolic health, and enhancing insulin sensitivity, especially in those with pre-diabetes. The current body of research includes randomized controlled trials and systematic reviews, indicating moderate evidence for benefits such as improved glucose metabolism and favorable effects on muscle function. While interest in deep seawater extracts is growing, the research remains less comprehensive compared to more established supplements, yet it shows promise in enhancing overall health.

Benefits

Deep seawater extracts provide multiple evidence-backed benefits, primarily attributed to their magnesium content. A systematic review has demonstrated that magnesium supplementation can significantly improve insulin sensitivity, especially in patients with impaired glucose tolerance, with statistical significance (p < 0.05). Chronic use of these extracts has also been associated with reductions in body fat percentage and increases in basal metabolic rate and muscle mass, particularly among healthy individuals. Notably, individuals with pre-diabetes appear to benefit most, with measurable improvements in metabolic parameters visible within approximately 12 weeks of supplementation. Overall, deep seawater extracts show potential for positive impacts on metabolic health.

How it works

The primary mechanism by which deep seawater extracts enhance health is through the role of magnesium in boosting insulin sensitivity. Magnesium acts as a crucial cofactor in numerous enzymes involved in glucose metabolism, facilitating insulin signaling and improving insulin action. It has a particular influence on tyrosine kinase activity, which is vital for effective insulin receptor signaling. When consumed in mineral-rich water forms, magnesium from these extracts demonstrates favorable bioavailability, ensuring significant absorption and effectiveness.

Side effects

Deep seawater extracts are generally considered safe when taken at recommended dosages. Common side effects reported in over 5% of users include gastrointestinal issues such as diarrhea, nausea, and abdominal cramps, especially when doses are elevated. Less frequent adverse effects, occurring in 1-5% of users, include muscle weakness, fatigue, and dizziness. Rarely (<1%), severe gastrointestinal reactions or cardiac arrhythmias may occur in individuals consuming very high doses. Caution is advised for those on specific medications, particularly blood thinners, due to potential absorption interactions. Individuals with severe kidney disease should avoid high magnesium doses, and pregnant or breastfeeding women should consult a healthcare provider before use.

Dosage

The minimum effective dosage for deep seawater extracts is around 300-350 mg of magnesium per day, based on clinical studies. The optimal dosage typically ranges from 300 to 500 mg per day, preferably divided into two doses to minimize gastrointestinal discomfort. Long-term use is generally considered safe at doses not exceeding 350-400 mg per day. For enhanced absorption and to minimize potential side effects, these extracts should ideally be taken with meals. They are available in several forms, including mineral-rich water, capsules, and powders, with food consumption promoting increased bioavailability.

FAQs

Are deep seawater extracts safe?

Yes, they are generally safe within recommended doses, though high doses may lead to gastrointestinal issues.

When is the best time to take it?

It is best taken with meals to reduce gastrointestinal side effects.

What results can I expect?

You can expect improvements in insulin sensitivity and metabolic markers within a few weeks to months.

Is it a weight loss solution?

No, it's not a quick fix for weight loss; it supports long-term metabolic health.
