Magnesium (UK)

Nu Skin's Magnesium supplement provides a bioavailable form of magnesium that supports muscle function, energy production, and healthy sleep patterns. Magnesium deficiency is surprisingly common in the UK — the NDNS data shows that a significant proportion of British adults, particularly women, don't meet the recommended daily intake from diet alone. Processed foods, depleted soil, and the typically low consumption of magnesium-rich foods (dark leafy greens, nuts, seeds) in the average British diet all contribute to this shortfall.

What Sets This Magnesium Apart

Not all magnesium supplements are created equal, and the form matters considerably. Magnesium oxide — the cheapest and most common form in high-street supplements — has a bioavailability of roughly 4%, meaning 96% of what you swallow passes straight through. Nu Skin's formulation uses more absorbable magnesium forms that your body can actually utilise effectively.

At £19.64, it's one of the most accessible products in the Pharmanex range. The daily dose provides a meaningful contribution to the 375mg NRV for magnesium, helping to bridge the gap between dietary intake and optimal levels. We've noticed the most obvious benefit with sleep quality — falling asleep faster and waking up less during the night, particularly during stressful periods. That's consistent with the published research: a 2012 study in the Journal of Research in Medical Sciences found that magnesium supplementation significantly improved subjective sleep quality in elderly participants over 8 weeks.

If you live in a soft water area (Scotland, Wales, North West England, Devon, Cornwall), you're getting less magnesium from your tap water than someone in London or the South East, where hard water contains higher mineral levels. It's a small factor, but it compounds with dietary shortfalls.

Key Ingredients

Magnesium: An essential mineral involved in over 300 enzymatic reactions in the body. Key functions include muscle contraction and relaxation, energy metabolism (converting food into ATP), nervous system regulation, and bone health. The NRV is 375mg daily — many UK adults consume only 200-270mg from food.

How to Get the Most from Magnesium

Take with your evening meal. Magnesium's muscle-relaxing and sleep-supporting properties make evening dosing logical, and taking it with food improves absorption while reducing any chance of mild stomach discomfort. Avoid taking it at the same time as calcium supplements or calcium-rich foods in large quantities, as they can compete for absorption.

If you're taking LifePak+, check the magnesium content in that formula first. LifePak+ includes some magnesium, so you may want to adjust your standalone magnesium dose accordingly. Your GP can also check your magnesium levels via a blood test if you suspect a significant deficiency — though it's worth noting that serum magnesium isn't a perfect measure, as most magnesium is stored in bones and soft tissue rather than blood.

Frequently Asked Questions

Can I get Nu Skin Magnesium delivered in the UK?

Yes — ships from Nu Skin's UK warehouse, typically 3-5 working days across England, Scotland, Wales, and Northern Ireland.

When's the best time to take magnesium?

Evening, with dinner. The muscle-relaxing properties support sleep, and taking it with food improves absorption. Some people prefer splitting the dose — half with lunch, half with dinner — which is also fine.

Will magnesium help with muscle cramps?

Magnesium plays a direct role in muscle contraction and relaxation. While the NHS notes that muscle cramps have many causes, magnesium supplementation is commonly recommended when dietary intake is insufficient. If cramps persist, see your GP to rule out other causes.

Can I take this alongside LifePak+?

Yes, but check the combined magnesium intake. LifePak+ contains some magnesium, so adding a standalone supplement gives you a higher total dose. The tolerable upper level for supplemental magnesium is 350mg (EFSA), so stay within this combined limit from supplements — magnesium from food doesn't count toward this cap.

Important Information

Food supplement. Do not exceed the recommended daily intake. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Keep out of reach of young children. If you are pregnant, breastfeeding, taking any medication, or under medical supervision, consult a doctor or healthcare professional before use.
