Three forms of magnesium. One supplement. Ninety capsules. Magnesium 3 Complex combines magnesium glycinate for sleep and calm, magnesium malate for energy and recovery, and magnesium taurate for cardiovascular and nervous system health — with vitamin B6 to enhance magnesium's cellular transport and zinc to amplify its immune and hormonal activity. Vegan. Halal approved. Kosher approved. This is what a complete magnesium supplement looks like.
Why Three Forms of Magnesium Changes Everything
Magnesium is involved in over 300 biochemical reactions in the body. Yet most magnesium supplements deliver a single form — typically oxide, citrate or glycinate — and leave the rest of magnesium's biology unaddressed. The form of magnesium determines both how well it absorbs and where it directs magnesium in the body. Picking one form means picking one benefit.
Magnesium Glycinate — the calm and sleep form. Glycine acts as an inhibitory neurotransmitter in the central nervous system. When magnesium is bound to glycine, both the mineral and the amino acid deliver calming effects simultaneously. Magnesium glycinate is the most bioavailable form, absorbed without gastric irritation, and is the form most consistently studied for sleep onset, anxiety reduction and muscle cramping. For those under chronic stress or with poor sleep, glycinate is the starting point.
Magnesium Malate — the energy and recovery form. Malic acid is a direct participant in the Krebs cycle — the cellular pathway through which mitochondria produce ATP. Binding magnesium to malate means delivering it directly to the energy production pathway. Magnesium malate is specifically studied for fatigue-related conditions including fibromyalgia and chronic fatigue syndrome, as well as post-exercise muscle soreness and recovery. This is the form that makes magnesium relevant to active people.
Magnesium Taurate — the heart and nervous system form. Taurine is an amino acid with a specific role in cardiovascular regulation — it stabilises cell membranes, regulates electrical signalling in the heart and controls calcium handling in cardiac muscle. Bound to magnesium, taurate delivers both the mineral and the amino acid to cardiovascular tissue. Magnesium taurate is the most studied form for blood pressure support, heart rhythm stabilisation and autonomic nervous system regulation.
Research published in Nutrients confirms magnesium deficiency is widespread in Western populations — estimated at 45–50% of adults — and is associated with increased risk of cardiovascular disease, type 2 diabetes, osteoporosis and mood disorders. Magnesium 3 Complex addresses this deficiency across all three of its major physiological roles simultaneously.
Why Competitors Fall Short
Standard magnesium oxide tablets — the pharmacy default, the worst choice for absorption. Magnesium oxide has approximately 4% bioavailability. The majority is excreted rather than absorbed. Despite being the cheapest and most commonly sold form, oxide provides almost no meaningful magnesium to the body at typical doses. The three forms in Magnesium 3 Complex have bioavailability of 80–90%, making the comparison effectively no comparison at all.
Single-form glycinate supplements — good sleep, nothing else. Magnesium glycinate alone addresses the calming and sleep aspect of magnesium biology but does nothing for cellular energy production or cardiovascular regulation. Most premium single-form supplements stop at glycinate, leaving the malate and taurate benefits entirely on the table.
BiOptimizers Magnesium Breakthrough (7 forms) — over-diversified and expensive. Seven forms sounds more comprehensive than three, but at the dose spread across seven carriers, none approach a meaningful concentration. Magnesium 3 Complex concentrates on the three clinically distinct forms with the strongest evidence base, at a per-capsule cost a fraction of Magnesium Breakthrough's premium price.
What's in Every Capsule
The three-form magnesium matrix:
-
Magnesium Glycinate · highest bioavailability form · absorbed via amino acid transport pathway · calming and anxiolytic effects from glycine · supports sleep onset and sleep quality · relieves muscle cramps and spasms without gastric side effects
-
Magnesium Malate · bound to malic acid (Krebs cycle intermediate) · supports ATP synthesis and mitochondrial energy production · reduces physical fatigue and post-exercise soreness · particularly beneficial for chronic fatigue and fibromyalgia presentations
-
Magnesium Taurate · bound to taurine (cardiovascular amino acid) · supports blood pressure regulation and heart rhythm stabilisation · calming effects on the autonomic nervous system · the cardiovascular form of magnesium
The absorption and immune co-factors:
-
Vitamin B6 · facilitates magnesium transport into cells, increasing intracellular magnesium concentrations · co-regulates neurotransmitter synthesis (serotonin, dopamine, GABA) alongside magnesium · EU-authorised claims for immune function, energy metabolism, hormonal activity and reduction of tiredness and fatigue
-
Zinc · cofactor for over 300 enzymes shared with magnesium · supports immune defence, protein synthesis and DNA repair · EU-authorised claims for cognitive function, testosterone, skin, hair and nails, immune function, bone maintenance and antioxidant protection

How to Take It
Take 1 capsule 1 to 3 times per day, with food, or as required. Starting with 1 capsule daily and increasing gradually allows you to assess tolerance — though these three forms are well-tolerated at standard doses without the gastric side effects associated with oxide or high-dose citrate.
At 1 capsule daily: 90-day supply. At 3 capsules daily: 30-day supply. For sleep support, take the daily dose in the evening. For energy and recovery, split the dose with morning and post-workout. For cardiovascular or nervous system support, a consistent twice-daily schedule is recommended.
For comprehensive mineral support, pair with Lipovita D3 K2 — vitamin D3 and K2 work synergistically with magnesium for calcium regulation and bone health. For immune system depth, explore the Immunity UK collection for complementary zinc, vitamin C and probiotic options.
Is This You?
- You know you need magnesium but want all three key biological roles addressed — sleep, energy and cardiovascular — rather than just one
- You take a single-form magnesium glycinate for sleep but feel you need more energy during the day and better heart support — this is the logical upgrade
- You need halal and kosher certified magnesium — almost no magnesium complex on the market carries both
- You deal with chronic fatigue, fibromyalgia or post-exercise soreness and haven't tried the malate form specifically targeted at cellular energy
- You want zinc and B6 enhancing magnesium's cellular uptake alongside supporting immunity, skin, hair, nails and testosterone without a separate supplement
- You want flexible dosing — 1 to 3 capsules daily means this adapts from a maintenance 90-day supplement to an intensive 30-day protocol

Questions We Get Asked
Why use three forms of magnesium instead of just one?
Each form of magnesium is bound to a different carrier molecule that determines where and how it works in the body. Glycinate targets sleep, calm and muscle relaxation via the inhibitory neurotransmitter glycine. Malate targets cellular energy production via the Krebs cycle intermediate malic acid. Taurate targets cardiovascular health via taurine's role in heart and blood vessel regulation. No single form does all three. A triple-form complex is the only way to address all three simultaneously.
Is this product halal and kosher certified?
Yes to both. Magnesium 3 Complex is halal approved and kosher approved throughout — including the magnesium forms, zinc, vitamin B6 and the capsule shell. It is also vegan and suitable for vegetarians, making it one of the most inclusively certified magnesium supplements available in the UK.
Can I take this with other magnesium supplements?
Generally not recommended — this complex already provides three targeted forms of magnesium. Adding a separate magnesium supplement risks exceeding the tolerable upper intake. Magnesium 3 Complex is designed to be a complete magnesium protocol on its own. If you are under medical supervision for a specific condition, consult your GP before combining magnesium supplements.
Is magnesium taurate good for anxiety and the nervous system?
Yes. Taurine functions as an inhibitory neurotransmitter and helps regulate the autonomic nervous system — specifically the balance between sympathetic (stress) and parasympathetic (rest) activity. Combined with magnesium's role in regulating GABA and NMDA receptor activity, magnesium taurate has a calming effect on the nervous system that complements the direct anxiolytic effect of magnesium glycinate in the same formula.
How does vitamin B6 help magnesium work better?
Vitamin B6 facilitates the active transport of magnesium into cells, increasing intracellular magnesium concentrations beyond what magnesium supplementation alone achieves. B6 also co-regulates key neurotransmitters — serotonin, dopamine and GABA — that magnesium influences. The combination of B6 and magnesium for mood, sleep and stress is one of the most studied nutrient pairings in nutritional psychiatry. The zinc in this formula further amplifies enzyme activity and immune function shared with magnesium.
Food supplements should not replace a varied diet or healthy lifestyle. Halal and kosher approved. Vegan. Consult your GP before use if pregnant, breastfeeding, managing a diagnosed health condition or taking prescribed medication — particularly if taking medications for blood pressure, heart conditions or diabetes, as magnesium may interact with certain drugs.
