Ismaning – September 10, 2026 -- As daylight hours shrink, many people notice a familiar slump: low energy, tension, and a mood that dips no matter how much comfort food is on offer. Health experts point to a lack of light as the main culprit, since shorter, darker days throw off the body's internal clock and can trigger sluggishness and reduced mental resilience.
Sunlight and movement reset the body's rhythm
Direct sunlight with UVB rays triggers vitamin D production in the skin, while bright light entering through the eyes regulates serotonin and melatonin levels. Specialists recommend getting at least 30 to 40 minutes of light exposure daily, either through a UV-filtering daylight lamp or a walk or jog during the brightest part of the day -- even cloudy skies still let enough light through.
Physical activity delivers a second benefit. Reduced movement in winter allows muscles to tighten and stiffen, which strains the circulatory system and drags down mood further. Daily exercise, by contrast, helps release stress and lifts overall wellbeing.
Muscles and nerves need extra micronutrient support in winter
During low-motivation winter phases, the nervous system and muscles receive less support from the body's altered metabolism. Magnesium and B vitamins play a central role here: both help buffer stress, support energy production, and maintain normal nerve function. Typical winter eating habits often supply enough calories but too few of these nutrients, leaving a gap that a targeted supplement can help close.
A magnesium and B-vitamin combination targets the seasonal gap
Protina Pharmazeutische GmbH offers Magnesium-Diasporal Pro Muskeln und Nerven, a formula combining high-dose magnesium with a vitamin B complex. It comes in patented two-phase tablets as well as a direct-stick format with a blackcurrant flavor that can be taken without water, anywhere and anytime. The company notes that supplementation is meant to complement, not replace, a balanced diet and regular movement in daylight.
Magnesium supports cellular energy production, normal muscle and nerve function, and helps buffer the body's stress response while easing tension and fatigue. B vitamins support normal psychological function, sustain the nervous system, and aid energy metabolism, helping the body manage stressful periods more calmly.
