Why choose the liquid form of marine magnesium?

Magnesium: an essential mineral too often overlooked

Magnesium plays a crucial role in our bodies. Involved in over 300 biochemical reactions, it contributes to energy production, muscle contraction, the proper functioning of the nervous system, and bone health. Yet, according to several nutritional studies, nearly 70% of the population has insufficient magnesium intake.

Persistent fatigue, muscle cramps, twitching eyelids, irritability: these are all signs that can indicate a magnesium deficiency. But be careful, not all magnesium supplements are created equal! The form you choose directly influences the amount that will actually be absorbed and used by your body. This is called bioavailability, a key concept that we will explore together.

In this article, we compare two forms of marine magnesium: dry marine magnesium (primarily in oxide form) and Algosource's Original Magnesium. Understanding their differences will allow you to make an informed choice tailored to your specific needs.

Before diving into the comparison, let's clarify a key concept: bioavailability. Imagine pouring water into a leaky bucket. Even if you pour a lot of water, only some of it stays in the bucket. This is exactly what happens with dietary supplements.

Bioavailability represents the proportion of a nutrient that actually reaches the bloodstream and can be used by the body. A supplement may boast a high magnesium content on its label, but if its bioavailability is low, your body will derive only limited benefit.

Several factors influence this bioavailability:

• The chemical form of magnesium (oxide, chloride, citrate, bisglycinate, etc.)
• The presence of other nutrients that facilitate or hinder absorption
• The state of your digestive system
• The administered dose (doses that are too high saturate the absorption mechanisms)

Dried marine magnesium is generally obtained by evaporating seawater, producing mainly magnesium oxide. This form is highly concentrated: magnesium oxide contains approximately 60% elemental magnesium, making it one of the richest forms available.

Bioavailability and efficacy

Here's the tricky part: despite its high concentration, magnesium oxide has relatively low bioavailability, generally estimated at between 4% and 15% according to studies. Why? Because this form is poorly soluble in water and requires significant gastric acidity to be broken down and absorbed.

Think of an effervescent tablet versus a regular tablet: the former dissolves easily in water, the latter can remain intact longer. Magnesium oxide is more like the latter.

Strengths

• High concentration: allows for the creation of smaller tablets for a given dose
• Cost advantage: generally cheaper to produce
• Natural origin: extracted from seawater
• Laxative effect: may be beneficial for people suffering from occasional constipation

Boundaries

• Low absorption: a large portion passes through the digestive system without being absorbed.
• Digestive problems: may cause diarrhea, bloating or intestinal discomfort, especially at high doses
• Variable efficacy: often requires high doses to achieve a therapeutic effect
• Gastric acid dependence: less effective in people with low gastric acid production (elderly people, antacid use)

For whom?

Dried marine magnesium may be suitable for people who:

• Looking for an economical supplement
• Suffering from chronic constipation (laxative effect desired)
• Having good digestive tolerance
• No particular absorption problems

AlgoSource's low-sodium natural magnesium represents a technological advancement in marine magnesium extraction. The term "low-sodium" means "low in sodium." Unlike simple evaporation, this magnesium undergoes a specific treatment that significantly reduces its salt (sodium chloride) content while preserving other beneficial minerals from seawater.

This process results in a mixture of magnesium salts (chloride, sulfate, hydroxide) with a balanced composition that promotes better assimilation by the body.

Bioavailability and efficacy

Low-sodium magnesium has a significantly higher bioavailability than pure magnesium oxide. The various salt forms present dissolve more easily and are absorbed more efficiently by the intestinal wall.

This improved bioavailability means that:

• You need lower doses to achieve the same effect
• The benefits materialize more quickly
• Less magnesium is "wasted" during intestinal transit
• Digestive side effects are generally reduced.

This is the major advantage of this form. Sodium (Na+) is the main component of table salt. While moderate salt consumption is normal and necessary, excess sodium is linked to several health problems:

• High blood pressure: Excess sodium promotes water retention and increases blood volume, which raises pressure on the arterial walls.
• Water retention: feeling of bloating, temporary weight gain
• Cardiovascular overload: increased workload of the heart
• Worsening of heart failure: in people already affected

People following a low-sodium (low-salt) diet for medical reasons can therefore take this magnesium without compromising their dietary efforts.

Magnesium plays a major protective role for the heart and blood vessels:

• Blood pressure regulation: Magnesium helps relax blood vessels and contributes to maintaining normal blood pressure
• Prevention of arrhythmias: participates in the regulation of heart rhythm
• Protection against atherosclerosis: helps limit calcium deposits in the arteries
• Reduction of oxidative stress: beneficial anti-inflammatory action for blood vessels

By choosing a low-sodium magnesium supplement, you benefit from magnesium's positive effects on the cardiovascular system without adding sodium, which could counteract these benefits. This is a consistent and intelligent approach, particularly for people at risk of cardiovascular disease.

Thanks to its composition and better absorption, low-sodium magnesium generally causes fewer digestive problems. Less magnesium remains in the intestine, therefore less osmotic effect (drawing water into the intestines) which is responsible for diarrhea.

Seawater naturally contains over 70 minerals. The manufacturing process of low-sodium magnesium preserves some of these beneficial trace elements, creating a more complete and "physiological" supplement.

Low-sodium marine magnesium is particularly recommended for:

• People with high blood pressure or cardiovascular risk
• People following a salt-free diet (heart failure, kidney failure, edema)
• Elderly people, whose absorption is often reduced
• People with a sensitive digestive system
• Those looking for a highly absorbable form of magnesium
• People wishing to prevent cardiovascular disease

Do I have cardiovascular or blood pressure problems?

If so, definitely choose a low-sodium form to avoid adding sodium to your diet.

I need to follow a low-salt diet, what magnesium supplement can I take?

Algosource's low-sodium marine magnesium is then your best ally.

I have a sensitive digestive system, which magnesium supplement won't give me a stomach ache?

Opt for a reduced salt form to limit discomfort.

I have a limited budget to spend on my magnesium supplement...

If price is a limiting factor and you have no contraindications, oxide may be suitable, but you may need to take higher doses.

I have a fairly significant deficiency, which form should I choose?

To quickly correct a significant deficiency, a well-assimilated form will be more effective.

• Take your magnesium in the evening: this promotes absorption, and the relaxing effect of magnesium can also help with sleep.
• Be patient: the effects of magnesium supplementation appear gradually, usually after 2-3 weeks.
• Consult a healthcare professional: especially if you have kidney disease (magnesium is eliminated by the kidneys), are taking medication, or are unsure of your needs.

You need to choose a magnesium that is suitable for your personal situation.

Dried marine magnesium (oxide) remains an affordable option and may be suitable for people without specific medical conditions, with variable digestive tolerance and a limited budget. However, its low bioavailability limits its actual effectiveness.

Algosource's Original Magnesium represents a relevant technological advancement, particularly for:

• People concerned about their cardiovascular health
• Those who follow a low-salt diet
• People looking for a highly absorbable form
• Those with a sensitive digestive system

Investing in a more easily absorbed form is often profitable: you use less to get the same benefits, and you limit unpleasant digestive side effects.

Your cardiovascular health is a precious asset. If you are concerned about hypertension or wish to prevent cardiovascular disease, choosing our Original Magnesium is part of a coherent and comprehensive approach to preserving your health.

Remember that dietary supplements are not a substitute for a balanced diet rich in magnesium (green vegetables, nuts, whole grains, dark chocolate, legumes). They are used as a supplement when dietary intake is insufficient or when needs are increased (stress, intense physical activity, pregnancy).

Your body deserves the best. Choose consciously!
