Why Magnesium Matters More in Summer: Energy, Sweat, and Staying on Top of Your Levels

Warmer weather brings longer days, more outdoor activity, and — for many people — more sweating than usual. In this post, we'll look at why magnesium is a mineral worth paying attention to in summer, what it actually does in the body, and how to keep your levels topped up.

The Mineral You Lose Without Noticing

Magnesium is involved in over 300 enzymatic reactions in the body, but one detail often gets overlooked: it's lost through sweat. As temperatures rise and activity increases — whether that's a daily walk, a run, or simply spending more time outdoors — your magnesium losses can quietly add up.

Combined with the fact that magnesium isn't always abundant in modern diets to begin with, summer can be a season where awareness of this mineral matters more than people realise.

What Magnesium Actually Does

Magnesium supports several core functions that are easy to take for granted until they're running low:

• Normal muscle function — relevant for anyone increasing activity levels in summer
• Normal nervous system function — supports everyday nerve signalling
• Normal psychological function — contributes to a stable, balanced mood
• Reduction of tiredness and fatigue — particularly relevant when heat and activity combine
• Electrolyte balance — works alongside sodium and potassium to help regulate fluid balance

Why Multi-Source Matters

Not all magnesium is created equal. Different forms of magnesium vary in how readily the body can absorb and use them, which is why formulas combining multiple sources are often considered a more comprehensive approach than a single-form supplement.

Nutripolis's CompleMag (£19.99) is a multi-source magnesium complex combining four bioavailable forms of magnesium with B vitamins and potassium — designed to support energy, muscles, nerves, and mental focus in a single daily formula.

Spotting the Signs

Because magnesium's role is so foundational, the effects of running low are often non-specific — general tiredness, reduced focus, or muscle tension after activity. None of these are unique to magnesium, which is exactly why it's a mineral that's easy to underestimate.

If you're spending more time active outdoors this summer, it's worth considering whether your overall mineral intake matches your increased output.

Simple Ways to Stay on Top of It

• Stay consistent with hydration — water alone doesn't replace lost electrolytes
• Pay attention to whole-food sources — leafy greens, nuts, seeds, and wholegrains all contribute dietary magnesium
• Consider a targeted supplement during periods of higher activity or heat exposure
• Listen to your body — persistent fatigue or muscle tension is worth addressing, not ignoring
