Mag-fusion is formulated with vitamins and minerals in their bioactive and coenzymated forms, selected for their high bioavailability and compatibility with the body’s physiological processes. This allows for more efficient absorption and direct use of nutrients, without the need for prior metabolic conversions. Unlike many supplements that use less effective forms, Mag-fusion provides active compounds that the body can immediately utilise.
Based on the principles of micronutrition, Mag-fusion is especially suitable for individuals with specific nutritional needs or an active lifestyle, who are looking for a reliable, well-formulated supplement to support functional balance and overall wellbeing.
In Mag-fusion, magnesium is supplied in the form of pure magnesium citrate, an organic salt known for its high bioavailability, good digestive tolerance and superior absorption compared to inorganic forms such as magnesium oxide.
Each daily dose provides 247 mg of magnesium citrate, a quantity carefully adjusted to comply with the safety recommendations of the Scientific Committee on Food (SCF), which sets a tolerable upper intake level of 250 mg/day for dissociable magnesium salts in food supplements.* This ensures effective supplementation without compromising digestive comfort.
*: Scientific Committee on Food (SCF), Opinion on the Tolerable Upper Intake Level of Magnesium, SCF/CS/NUT/UPPLEV/54 Final, 11 October 2001.
Unlike other supplements that combine magnesium citrate with magnesium oxide, a mixture known as “buffered citrate”, which has poor absorption, Mag-fusion contains only pure magnesium citrate, without oxide, ensuring superior absorption and efficacy.
Mag-fusion provides the three B vitamins most relevant to energy and cardiovascular metabolism — B6, B9 (folate) and B12 — in their coenzymated forms, meaning they are ready to be used by the body without requiring liver conversion.
It includes:
Vitamin B6 as pyridoxal-5’-phosphate (P5P)
Folate (B9) as L-5-methyltetrahydrofolate (5-MTHF)
Vitamin B12 as methylcobalamin
These active forms are the same ones the body uses functionally, significantly improving bioavailability and physiological effectiveness. Their use avoids the limitations of less efficient forms such as pyridoxine, folic acid or cyanocobalamin, which require several conversion steps before becoming usable.
This formulation is particularly beneficial for:
People with genetic polymorphisms (such as the MTHFR gene) that impair the activation of standard folic acid
Individuals with B12 absorption difficulties, common in older adults, those with atrophic gastritis or low intrinsic factor production
Cases where the liver fails to convert vitamin B6 effectively into its active form (P5P), as seen in certain liver or metabolic disorders
B6, B9 and B12 in coenzymated form directly support key functions such as:
Cellular energy metabolism
Homocysteine regulation
Neurotransmitter synthesis
Normal cognitive and nervous system function
Thanks to this combination, Mag-fusion provides efficient and scientifically backed supplementation for those seeking fast, effective support against nutritional imbalances or increased physiological demands.
Mag-fusion delivers vitamin D in the form of cholecalciferol (D3), the variant with the highest bioavailability and physiological efficacy for the human body. This fat-soluble form is the same produced naturally by the body through sun exposure, promoting better intestinal absorption and use by target tissues.
Vitamin D3 contributes to:
The maintenance of normal bones and teeth
The normal function of the immune system
The absorption and utilisation of calcium and phosphorus
With its inclusion of cholecalciferol and a daily dose of 2000 IU, Mag-fusion provides effective and safe support for bone, muscle and immune health, particularly in people with low sun exposure, progressive bone loss, or increased requirements for this essential micronutrient.
The formula for Mag-fusion was developed entirely by the scientific team at Nutribiolite, made up of specialists with advanced academic backgrounds in chemistry, pharmacy and nanomedicine. This technical expertise, combined with extensive experience in biomedical research and the pharmaceutical industry, ensures a formulation that is rigorous, effective and evidence-based.
Each ingredient has been carefully selected for its bioavailability, safety and efficacy, in accordance with European regulations on food supplements. The development of the product reflects a vision of micronutrition as a scientific tool, integrating the latest knowledge with a strong commitment to consumer health.
From raw material selection to final production, all processes comply with Good Manufacturing Practices (GMP) and meet the food safety standards required by the European Union.
Each bottle of Mag-fusion contains 120 vegetable capsules, providing continuous supplementation for 60 days when taken as directed (2 capsules per day). This format has been designed to offer an appropriate duration without interruptions, making it ideal for sustained micronutrition programmes.
The capsule presentation allows for practical and flexible intake, ideal for those who value effectiveness, consistency and simplicity in their daily nutritional routine.
Mag-fusion is more than just a magnesium supplement, it is a precisely designed formula that supports multiple physiological functions simultaneously. Its combination of chelated magnesium (citrate) and essential vitamins in bioactive and coenzymated forms (P5P, 5-MTHF, methylcobalamin and D3) provides comprehensive and coordinated support for key processes such as energy production, neuromuscular function, homocysteine balance and cardiovascular health.
Unlike many conventional supplements, Mag-fusion combines highly bioavailable magnesium with essential nutritional cofactors that work synergistically. The inclusion of vitamin B6 as P5P, folate as 5-MTHF, and vitamin B12 as methylcobalamin allows for direct absorption and utilisation by the body, optimising key metabolic pathways and correcting deficiencies more efficiently.
Vitamin D3 and magnesium work together in synergy to maximise their benefits: vitamin D3 enhances the intestinal absorption of magnesium, while magnesium is essential for the activation and proper function of vitamin D3. Together, they optimise calcium absorption — vital for the health of bones and joints — improve muscle integrity, and support the normal function of the immune system. This complementary interaction makes magnesium and vitamin D3 an essential nutritional pairing for maintaining overall health.
Mag-fusion combines magnesium with vitamins B6, folate and B12 in their coenzymated and bioactive forms, essential for the metabolism of homocysteine — a compound derived from methionine, an amino acid found in food. Elevated levels of homocysteine are associated with increased cardiovascular risk. These active vitamins support the remethylation and transsulfuration pathways, transforming homocysteine into safe or beneficial substances, while magnesium acts as a key cofactor in these processes.
Magnesium and B-group vitamins in Mag-fusion play a direct role in cellular energy metabolism, help reduce tiredness and fatigue, and contribute to the normal functioning of the nervous system. This makes Mag-fusion an ideal supplement for individuals with active lifestyles, high levels of physical or mental stress, or anyone simply looking to maintain daily wellbeing with a solid nutritional foundation.
Taking care of your well-being has never been easier: simply take one capsule twice a day and enjoy essential nutrients for your energy, balance, and overall health.
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.

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.
