Viridian High Strength Magnesium 300mg (90 Capsules)

Magnesium is one of the most consistently useful supplements anyone can take, full stop. Viridian's High Strength version delivers 300mg per capsule, which is a proper functional dose rather than a token amount.

If you only buy one supplement on this list, this should probably be it. Magnesium is one of the most chronically under-supplied minerals in the UK diet and it's involved in hundreds of processes the body relies on every day.

Why magnesium matters

Let's start with the official authorised nutrient claims because they actually tell the full story here. Magnesium contributes to reduction of tiredness and fatigue. Magnesium contributes to electrolyte balance. Magnesium contributes to normal energy-yielding metabolism. Magnesium contributes to normal functioning of the nervous system. Magnesium contributes to normal muscle function. Magnesium contributes to normal protein synthesis. Magnesium contributes to normal psychological function. Magnesium contributes to the maintenance of normal bones. Magnesium contributes to the maintenance of normal teeth.

That's nine authorised nutrient claims for a single mineral. There are very few supplements with that kind of breadth across the official claims list. It's a strong signal of how deeply magnesium is involved in everyday body function.

A lot of customers come to magnesium for one specific reason (sleep, muscle cramps, energy, stress) and quickly realise they were probably running on the low side of optimal across the board.

Who tends to take it

Pretty much everyone, honestly. But specifically: customers struggling with sleep quality. People who deal with muscle cramps, particularly at night. Active and gym-going customers using it for recovery. People in high-stress periods looking for nervous-system support. Midlife customers working on energy, mood and sleep all together. Anyone who feels their daily routine could do with a quiet upgrade.

It pairs naturally with a quality vitamin D (the two work together in bone-and-muscle context), a sensible B-complex, and the rest of a foundation routine. Browse the Sleep & Calm collection, the Stress & Mood collection, and the Muscle & Strength collection for the wider routine ranges.

What makes Viridian's version stand out

A proper 300mg dose, quality form of magnesium (we'd recommend checking the bottle for the specific form Viridian uses, which is typically one of the well-absorbed types like citrate, bisglycinate or malate). Clean carrier capsule, no industrial fillers. No magnesium stearate, no titanium dioxide, no synthetic colourings. Vegetarian-suitable shell.

The form of magnesium genuinely matters. Cheap supplements use magnesium oxide because it's cheap and lets manufacturers print a big number on the label. The catch is the body absorbs and uses very little of it. Better forms (citrate, bisglycinate, malate, taurate, glycinate) are more bioavailable, more comfortable on the stomach, and worth the small extra cost.

How to take it

One capsule daily with food, or as your practitioner advises. Many customers prefer to take magnesium in the evening because it pairs well with a wind-down routine, though there's no hard rule. Splitting the dose into morning and evening can work well if you're using a higher daily amount.

Very high doses of magnesium can have a loosening effect on the bowel. If that happens, drop the dose. Not harmful, just an over-shoot signal.

If you have kidney problems, you should not take a magnesium supplement without specific GP approval. If you're on prescription medication (particularly certain antibiotics, blood pressure medication, or osteoporosis medication), check with your pharmacist as the timing of magnesium can affect absorption of other medications.
