Top Supplements for Energy and Tiredness (UK 2025)
1) B-Complex Vitamins — The Energy Co-Factors
B6, B12, folate and niacin convert food into cellular energy. Deficiency = fatigue, brain fog, low motivation.
✅ Try Vitamin B Complex — high strength, filler-free, UK-made.
2) Magnesium — Anti-Fatigue Mineral
Involved in 300+ energy reactions and muscle/nerve function. Low magnesium is a fatigue common denominator.
✅ Explore Triple Magnesium Complex — gentle glycinate-led, highly absorbable.
3) Vitamin D3 + K2 — Mood, Immunity & Rhythm
Low D is linked with tiredness and low mood, especially in UK winters. K2 helps utilisation.
✅ Boost with Vitamin D3 + K2.
4) Ashwagandha — Stress-Balanced Energy
Adaptogen support for busy, stressed lifestyles. Helps dial down the “wired-but-tired” feeling.
✅ Choose Ashwagandha.
5) Lion’s Mane & Mushroom Complex — Focus + Resilience
Functional mushrooms (Lion’s Mane, Cordyceps, Reishi) support focus, stamina and stress resilience.
✅ See Mushroom Complex.
6) Omega-3 — Brain & Mitochondrial Support
