Why a five-form magnesium supplement?
Most magnesium supplements use a single form of magnesium. But every form behaves differently: some are gentler on the stomach, some are more soluble, some bring a partner molecule with its own role in the body, and some reach different tissues more efficiently.
Mag⁵Plex⁷⁵⁰ combines five forms of magnesium in equal amounts, so you benefit from the strengths of each one. Then we add P5P, the active form of vitamin B6 that works alongside magnesium, and BioPerine®, a natural bioavailability enhancer.
The result is a complete, high-absorption magnesium supplement in a single capsule.
Five forms, five strengths
- Bisglycinate: the calming magnesium, gentle on the stomach.
- Citrate: excellent bioavailability.
- L-pidolate: high intracellular penetration.
- Gluconate: highly soluble and well absorbed.
- Malate: paired with malic acid, a player in energy production.

Every ingredient in this magnesium supplement, explained
Nothing hidden, nothing unnecessary. Here is everything inside each Mag⁵Plex⁷⁵⁰ capsule and why it is there.
Magnesio bisglicinato
Known as “the calming magnesium”. Magnesium is bound to two molecules of the amino acid glycine, which gives it optimum bioavailability and makes it gentle on the stomach, without the laxative effect of some other forms. It provides 30 mg of elemental magnesium.
Magnesio citrato
Magnesium bound to citric acid, one of the most widely used forms thanks to its excellent bioavailability and its support for digestion. It provides 45 mg of elemental magnesium.
Magnesio L-pidolato
Magnesium bound to pidolic acid (pyroglutamic acid), known for its high bioavailability and intracellular penetration. In a laboratory study of different magnesium salts, magnesium pidolate was the most efficient at enhancing magnesium transport across an in vitro model of the blood-brain barrier (Romeo et al., 2019). It provides 12.9 mg of elemental magnesium.
Magnesio gluconato
Magnesium bound to gluconic acid. Gluconate is highly soluble and is considered one of the most bioavailable magnesium salts, and it also contributes to the body’s electrolyte balance. It provides 7.5 mg of elemental magnesium.
Magnesio malato
Magnesium bound to malic acid. Malate helps the intestines absorb magnesium, and malic acid itself takes part in the Krebs cycle, the pathway that produces energy in your cells, which is why it is linked with energy production, endurance and reduced muscle fatigue. It provides 22.5 mg of elemental magnesium.
Vitamin B6 as pyridoxal 5′-phosphate (P5P)
P5P is the active form of vitamin B6, the form your body uses directly, without first converting it in the liver. It is the sport-enhancing form of B6: it contributes to normal energy-yielding metabolism and to normal protein and glycogen metabolism, the processes that fuel training and repair muscle.
BioPerine® black pepper extract (Piper nigrum fruit)
A patented extract standardised to at least 95% piperine (19 mg per capsule). BioPerine® is a natural bioavailability enhancer: according to research published by its manufacturer, Sabinsa, it increases the absorption of nutrients including vitamin B6, selenium and beta-carotene, by supporting blood supply to the gut and the active transport of nutrients.
Hydroxypropyl methylcellulose (HPMC)
The plant-based capsule shell, free from gelatine.
Magnesium salts of fatty acids
Keeps the powder flowing freely during encapsulation for a uniform fill in every capsule.

Why endurance athletes need a magnesium supplement
The body holds around 25 g of magnesium, about 60% of it in the bones. It helps muscles recover from stress and fatigue, and athletes need more of it than less active people. Sweating and urination deplete magnesium, so daily needs can be high for athletes and sports enthusiasts, and very few sports drinks contain meaningful amounts of it.
Some research suggests that magnesium may improve endurance performance and help prevent cramps. Absorption can also be reduced by very high or very low protein intake and by alcohol, which makes a well-absorbed magnesium supplement even more valuable.
Athletes need B vitamins too. Exercise may increase the need for B vitamins, and low B-vitamin status may reduce the ability to perform at high intensity and to repair muscle (Woolf & Manore, 2006). In an earlier study, intakes below one third of the recommended amount of some B vitamins reduced VO₂max and anaerobic threshold within weeks (van der Beek, 1991). Athletes also face high mental demands, with notable rates of depressive symptoms reported among elite swimmers (Hammond, 2013), and both magnesium and vitamin B6 contribute to normal psychological function.
Built for the long game
- Runners & marathon runners: high mileage, high sweat losses, high magnesium turnover.
- Cyclists: long hours of sweat and muscle work in the saddle.
- Triathletes: three disciplines that stack up the highest training loads.
- Swimmers: heavy volume, early starts and high mental demands.
- Strength athletes: support for protein synthesis and muscle function.

Magnesium supplement: your questions answered
What is the best magnesium supplement?
Every magnesium form has its own strengths, so instead of choosing just one, Mag⁵Plex⁷⁵⁰ combines five: bisglycinate, citrate, L-pidolate, gluconate and malate. It adds active vitamin B6 (P5P) and BioPerine® to support absorption and the work magnesium does in the body.
Why take five forms of magnesium instead of one?
Each form brings something different: bisglycinate is gentle and calming, citrate is highly bioavailable, L-pidolate has high intracellular penetration, gluconate is very soluble and malate is paired with malic acid, which takes part in energy production. Together they make a more complete magnesium supplement.
How much magnesium is in each capsule?
Each capsule contains 750 mg of magnesium compounds, providing 117.9 mg of elemental magnesium (39% NRV), plus 14 mg of vitamin B6 as P5P and 20 mg of BioPerine®.
When is the best time to take a magnesium supplement?
Take 1 capsule per day with a meal and plenty of water. Consistency matters more than timing, so choose a meal you never skip; many athletes prefer the evening.
Is a magnesium supplement good for athletes?
Yes. Athletes lose magnesium through sweat and urine, and magnesium contributes to normal muscle function, electrolyte balance, energy-yielding metabolism and the reduction of tiredness and fatigue.
Why is vitamin B6 added to magnesium?
Vitamin B6 works alongside magnesium: both contribute to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue. We use P5P, the active form your body can use directly.
What does BioPerine® do?
BioPerine® is a black pepper extract standardised to at least 95% piperine. It is used as a natural bioavailability enhancer, supporting the absorption of nutrients such as vitamin B6.
Can I take Mag⁵Plex⁷⁵⁰ with zinc?
Yes. Magnesium and zinc are a popular pairing for athletes. If you want both, add LipoZinc¹²⁵ liposomal zinc to your daily routine.
Does a magnesium supplement have side effects?
At the recommended dose of 1 capsule per day, Mag⁵Plex⁷⁵⁰ is well tolerated. Large amounts of magnesium may have a laxative effect, so do not exceed the recommended daily dose. If you are pregnant, breastfeeding or taking medication, consult your doctor first.
