The best energy-boosting supplements contain key vitamins and minerals like Vitamin B12, B Complex, Iron, and Magnesium. B12 supports red blood cell production and nervous system function, while iron prevents fatigue by improving oxygen transport. Magnesium plays a role in energy metabolism, and adaptogens like Ashwagandha help manage stress-related fatigue.
The commonest deficiencies linked to fatigue include Vitamin B12, B6, Iron, Vitamin D, and Magnesium. B vitamins support metabolism and nerve function, iron is essential for oxygen transport, vitamin D contributes to muscle function and immunity, and magnesium helps with relaxation and sleep quality. If you suffer from constant and severe fatigue, see your GP to discuss possible causes.
B vitamins help convert food into ATP, the body's energy currency. B12 and B6 support red blood cell production, oxygen transport, and nerve function, ensuring your body efficiently produces and uses energy. A Vitamin B Complex supplement can help maintain steady energy levels throughout the day.
Both vitamins play an essential role in energy metabolism. Vitamin B12 supports red blood cell production and nerve function, whilst Vitamin B6 helps convert food into energy. You will feel very tired with a deficiency in either vitamin, but slightly low Vitamin B12 seems to be a more common than a deficiency in Vitamin B6.
B12 does not act like a stimulant in people who don’t have a deficiency. If you do, supplementing can gradually restore energy levels over days or weeks. Those who are not deficient may not notice an immediate boost, but consistent intake supports sustained energy.
