Viridian Organic Magnesium from Sea Lettuce 150mg (30 Capsules)

Magnesium is the mineral most adults in the UK could do with more of. It's involved in something like 300 enzyme reactions in the body. It helps with energy production, muscle function, nervous system function, and recovery from training. If you're tired all the time and your sleep feels twitchy, magnesium is one of the first things worth looking at.

Viridian's Organic Magnesium from Sea Lettuce is the whole-food version of the mineral. Not an isolated salt, not a synthetic compound. Magnesium as it occurs naturally in a marine plant.

What it is

A 30-capsule bottle of organic sea lettuce (a green seaweed), standardised to deliver 150mg of plant-source magnesium per daily capsule. Soil Association organic. Suitable for vegetarians and vegans. No fillers.

Why magnesium matters

Magnesium is a regulated nutrient with GB-authorised health claims. It contributes to:

• Reduction of tiredness and fatigue
• Normal muscle function
• Normal nervous system function
• Normal energy-yielding metabolism
• Electrolyte balance

Most people don't hit the reference daily intake. Whole foods like nuts, seeds, leafy greens and seaweeds get you most of the way there if you eat well, but a daily supplement is the simplest way to top up.

Why a whole-food source rather than magnesium glycinate or citrate

Magnesium glycinate and magnesium citrate are excellent supplemental forms, and we stock those too. They're isolated compounds that deliver a known dose of elemental magnesium in a bioavailable form.

Whole-food magnesium from sea lettuce is the other school of thought. You get magnesium as it occurs naturally in the plant, alongside the trace minerals and co-factors the plant produces with it. The dose per capsule is more modest, but it suits people who'd rather take a food-based supplement than a salt.

There's no wrong answer between the two. It comes down to which approach fits your routine and your preferences.

Who it suits

• People who already eat reasonably well and want a whole-food top-up rather than a high-dose isolated supplement
• Vegans and vegetarians
• Anyone working on sleep, recovery and daytime energy who wants a gentle daily option
• Long-time Viridian users

If you have kidney issues or are on prescription medication, check with your GP before adding magnesium to your routine.

Why Viridian

Viridian's magnesium-from-sea-lettuce capsules are organic, the magnesium content per capsule is stated clearly, and there's nothing else in the bottle that doesn't belong. The brand has built its name in independent UK shops on this approach.

How to take it

One capsule daily with food, or as directed by a practitioner. The 30-capsule bottle is a one-month starter, easy to drop in alongside an order of other staples.

If you want a higher daily dose, look at the magnesium glycinate or citrate options in our Vitamins & Minerals range, or pair this with a meal-led approach. Our guide How to Choose the Right Magnesium walks through the options.

What pairs with it

Magnesium pairs sensibly with Vitamin D3 (D contributes to normal immune function and maintenance of normal bones), a B-complex if your daily energy is patchy, and a good sleep routine. Browse the Sleep & Calm and Recovery collections for what fits alongside.
