Mag-fusion does more than provide magnesium. It combines magnesium citrate, vitamin D3, and vitamins B6, B9, and B12 because these nutrients are involved in related functions. Magnesium and vitamin D3 overlap in key areas such as the maintenance of normal bones and muscle function, and vitamin D also contributes to the normal absorption and utilisation of calcium and phosphorus. Vitamins B6, B9, and B12 complete the formula because they take part in energy metabolism and, together with magnesium, help support important functions of the nervous system. In addition, vitamins B6, B9, and B12 contribute to normal homocysteine metabolism, which is why their combination adds value compared with a magnesium-only supplement. The result is a more complete food supplement, with nutrients that work in the same areas and make more sense together than separately.
Mag-fusion provides 247 mg of elemental magnesium per daily dose, using magnesium citrate exclusively as its sole source. By avoiding blends with magnesium oxide, the so-called “buffered” forms, which are often used to increase total magnesium content, we ensure a more consistent and transparent formula.
Magnesium citrate is an organic salt highly valued for its excellent solubility and good digestive tolerance. From a chemical perspective, magnesium oxides and inorganic magnesium salts have lower solubility than organic salts such as citrate. In addition, our formula is developed without synthetic additives, making it an ideal choice for those looking for a daily food supplement designed to support mineral absorption.
Mag-fusion combines vitamins and minerals in bioactive and coenzymated forms, selected for their high bioavailability and their affinity with the body’s physiological processes. This supports efficient absorption and more direct use of nutrients, without prior metabolic conversion. In addition, the formula contains no synthetic additives and provides naturally sourced silica from bamboo extract, in line with a carefully designed and coherent composition. Compared with other supplements that use less usable forms, it offers active compounds particularly suited to people with specific nutritional needs or an active lifestyle who are looking for a reliable supplement to help maintain functional balance and overall wellbeing.
Looking after your wellbeing can be this simple. Take 1 capsule, 2 times a day and add a complete formula with key nutrients to your routine. Each pack contains 120 vegetable capsules, enough for 60 days. A practical and convenient format, designed to make consistency easier and support you day after day.
Choosing well-formulated supplements with ingredients in bioavailable forms is an informed decision that supports the body’s physiological functions. Smart supplementation isn’t about taking more, but about choosing better: essential nutrients in the right amounts and in forms that the body can absorb and use effectively.
Pure Magnesium Citrate
Magnesium is essential for maintaining energy production, proper nervous system and muscle function, and balanced electrolyte levels. It supports protein synthesis, psychological well-being, and the health of bones and teeth, while also helping to reduce tiredness and fatigue.
Vitamin D3 (Cholecalciferol)
Vitamin D3 supports the normal absorption and use of calcium and phosphorus, helping to maintain healthy blood calcium levels. It plays a key role in keeping bones and teeth strong, supporting muscle function, and promoting a healthy immune system.
as Pyridoxal-5′-phosphate
Vitamin B6 supports energy production, a healthy nervous system, and balanced homocysteine levels. It aids protein and glycogen metabolism, promotes psychological well-being, and helps reduce tiredness and fatigue.
Folate (5-MTHF)
Folate plays a crucial role in amino acid synthesis, healthy blood formation, and balanced homocysteine metabolism. It supports psychological well-being and helps reduce tiredness and fatigue.
Methylcobalamin
Vitamin B12 supports energy production, nervous system health, and balanced homocysteine metabolism. It aids red blood cell formation, promotes psychological well-being, and helps reduce tiredness and fatigue.

Here’s the truth about magnesium citrate supplements that many brands won’t tell you: While many products claim to contain “magnesium citrate,” they often use buffered citrate which still contains unreacted magnesium oxide to artificially boost the magnesium content on the label. MAG-FUSION takes a different approach – we use pure, fully reacted magnesium citrate with zero hidden magnesium oxide. This means you get exactly what’s on the label: clean, bioavailable magnesium citrate as dissociated salts.
This is a fantastic question that gets to the heart of supplement quality! Our 247 mg represents the maximum amount of magnesium you can get from pure magnesium citrate in a single capsule, while adhering to EFSA guidelines, which set a maximum of 250 mg daily magnesium from pure magnesium citrate for safety and effectiveness. If you see products advertising significantly higher amounts of “magnesium citrate” per serving, they’re likely using buffered citrate (which contains hidden magnesium oxide) but not disclosing this on their label. We believe in complete transparency, every milligram in Mag-fusion is pure, fully reacted magnesium citrate.
Activated B vitamins (P5P, methylcobalamin, and L-5-methyltetrahydrofolate) are already in their biologically active forms, unlike standard B vitamins that require conversion by your body. This means immediate biological availability and better effectiveness, especially for people with common genetic variations that affect B vitamin metabolism.
This is where the science gets really interesting! The relationship between vitamin D3 and magnesium is a perfect example of nutrient synergy. Not only does vitamin D3 help your body utilize magnesium more effectively, but magnesium is absolutely essential for activating vitamin D3 into its bioactive form. Without adequate magnesium, vitamin D3 can’t be properly converted into the form your body needs for bone health, immune function, and other critical processes. Many people take vitamin D3 supplements without realizing they might not get the full benefits if they’re low in magnesium. MAG-FUSION’s formulation ensures you get both nutrients in the right forms and amounts for optimal effectiveness.
For optimal absorption, take one capsule twice daily after meals with water.This divided dosing strategy maintains optimal nutrient levels throughout the day and enhances absorption.
Each bottle contains 120 capsules, providing a 2-month supply when taken as directed (1 capsule twice daily).
Mag-fusion isn’t just a magnesium supplement – it’s a comprehensive formula that addresses multiple aspects of nutrient metabolism. The combination of highly bioavailable magnesium citrate, activated B vitamins, and optimal D3 dosage works together to support energy metabolism, nervous system function, and overall wellbeing.
Do not exceed the recommended daily dose. The formula is optimized for effectiveness at the suggested serving size.
