Magnesium Gluconate nutritional supplement is designed to offer the essential mineral magnesium’s additional necessary amounts to promote a healthy diet and normal body functions. The presence of Magnesium is necessary.

The product is commercialized by Alfa Vitamins Laboratories, a reputable manufacturer of dietary supplements originated in Florida, USA. The company distributes products under its own brands or for other private labels in more than 51 countries.

The manufacturing processes are claimed to follow the Good Manufacturing Practices established by authorized organizations (FDA, USP, and DA).

The product is formulated for adults concerned with preventing and/or treating magnesium deficiency and many other conditions derived from low magnesium levels.

The manufacturer makes no straightforward, direct ailment claims but assumes they can be obtained from other sources.

The details offered by Alfa Vitamins about their product on the official page are limited to the complete list of ingredients and the recommended use, mainly because Magnesium-based supplements are prevalent. Information on its benefits and service is highly available.

The excellent reputation and experience of this company are, on the other hand, a strong reason why Magnesium Gluconateshould be considered to be of high quality and effective formula.


1) Magnesium Gluconate at a Glance

The presented formula is based on one active substance, which is Magnesium Gluconate. Magnesium is the fourth most abundant mineral in the body, necessary to fulfill around 300 metabolic processes. It is needed for the health of the nerves, muscles, and bones.

Deficiency of Magnesium is a common health issue, and doctors consider that the proper amounts of this mineral can’t be taken solely from dietary sources and need to be supplemented.

Deficiencies in Magnesium result in fatigue, nausea, loss of appetite, and weakness of the muscles.

Among the most common benefits of Magnesium Gluconate, we can find the antacid and laxative effects, regulate glucose (thus reducing the symptoms of diabetes), cardiovascular benefits (by regulating blood pressure), and positive impact on sleep processes and mental state of mind, and many others.

Research in the field showed that some of the claimed benefits are not supported by scientific data or clinical trials are inconsistent, and further research is required.

Magnesium based supplements are considered generally safe when taken in the suggested doses. Severe side effects like irregular heartbeat, confusion, or low blood pressure may occur when magnesium doses are very high. Death may also occur in some cases.


2) Details on Magnesium Gluconate Ingredients and Uses

Magnesium Gluconate contains the following ingredients: Magnesium (as Magnesium Gluconate), Dicalcium Phosphate, Microcrystalline Cellulose, Stearic acid, Magnesium Stearate, and Croscarmellose Sodium.

3) Is Magnesium Gluconate Right for You?

The formula is a mineral-based dietary supplement.

Magnesium is a nutrient considered essential for the proper function of many organs in the human body.

It is involved in a large variety of biochemical reactions, facilitates the transmission of nerve impulses (thus boosting brain power), helps in the detoxification process, regulates body temperature, reduces migraines, prevents and treats insomnia and hypertension, and promotes a healthy bone structure (thus preventing a common bone affection called osteoporosis).

Magnesium is present in fish, green leafy vegetables (spinach), whole grains, almonds (and other nuts in smaller quantities), avocado, dark chocolate, bananas, and dried fruits.

Proper amounts of Magnesium cannot usually be obtained from dietary sources, so it is better to supplement diet intakes.

Research has revealed no conclusive evidence to support Magnesium’s benefits in preventing heart attacks, improving endurance during athletic activity, or helping treat ADHD, anxiety, or hypertension.

Results have been positive for Magnesium in treating dyspepsia, magnesium deficiency, constipation, and eclampsia.

This supplement is not clinically researched. A single dose contains merely 7% of the daily recommended value. There is no mention of the adding of artificial stimulants, preservatives, or caffeine either. The side effects may occur when taken in vast amounts (doses under 350 mg per day are considered likely safe).

Magnesium doses vary with the age of the consumer. For complete information about the correct dosages, it is always best to consult a healthcare professional.


4) Magnesium Gluconate Benefits & Results

  • The formula comes with a low price for a month’s supply (under $2);
  • Safe online purchasing is available when using the manufacturer’s website;
  • Refund offered for online purchasing on the official site.

5) Magnesium Gluconate Product Warnings

  • No evidence of clinical trials involving the formula;
  • No free trial period;
  • Insufficient and mixed reviews from consumers;
  • Reduced percentage of the active substance (7%).

6) How Much Does Magnesium Gluconate Cost?

The price for a bottle representing a three month supply if the suggested dose is not exceeded is relatively low compared to similar products. Still, the quantity of the active substance is considerably lower when compared to other magnesium-based supplements.

Shipping charges greatly vary depending on the delivery zone or country. Online purchase is secured through the Secure Sockets Layer technology.

All company products come with a 100% quality assurance. A full refund is offered if the product is not used, and the security seal is not broken or tampered.


7) Directions For Taking Magnesium Gluconate

The suggested use is 1 tablet daily, preferably with a meal.

Does it Work

8) Bottom Line – Does It Really Work?

Magnesium Gluconate formula is an everyday nutritional supplement based on a derivate of Magnesium. The substance is a common ingredient in dietary supplements, and it is offered in various combinations by many other suppliers.

Testimonials from consumers point out that the formula’s labeling is confusing because it is written that the formula contains 550 mg of the active ingredient. In contrast, on the back label, it is noted that the content is only 30 mg.

The product is not evaluated by the FDA. In these cases, you should always consult a healthcare specialist before starting to use it.

I made an error in my review & cannot correct it, so adding this commet: Im my review of today (10/5/2022) I included the wrong DV for magnesium, which is approx 360mg/day NOT 1000-1200mg daily (that’s the DV for CALCIUM, not magnesium) SO SORRY AS THIS INFO is just horrible! And therefore I gave wrong # of pills one would need daily for mag gluconate too. I stand by the rest of my info. Humble apologies…

Have you tried this product?

I just don’t understand why supplement companies don’t put the elemental (pure) magnesium on the front label, instead of confusing us with another measurement, in this case, 550 mg which is clearly not the pure elemental amount in each tablet! This HAS to be deliberate, and I just learned that I’ve been taking much too little magnesium due to this (dishonest imho) labeling. Now I will always check the %DV for the serving amount. It’s not about the number of pills one has to take, rather it’s about the %DV on the ingredient label that we need to be wary of. In this case, it’s just 8% of the DV (daily value/requirement). Most adults need 1000-1200 mg of magnesium (pure/elemental) daily, so one would need to take about 20 mag gluconate pills at 8% each. This is just crazy and so misleading!

Misleading front labels!! CAUTION - read the back label carefully & check the %DV b4 buying!
Have you tried this product?

For me it had no visible effect. I stopped using it after 2 months and got another supplement based on a mineral and vitamin mixture which seems to be more effective.


Alfa Vitamins products may seem ineffective because of the quantity of magnesium which is low, but for me it worked just fine. No more fatigue and muscular pain now.
