Frequently Asked Questions

Which supplements improve energy levels?

Getting the right amounts of all the essential vitamins and minerals is important, but some of them will impact our energy levels more than others.


B vitamins like thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3) and vitamin B12 all contribute to the maintenance of normal energy levels.


Iron, magnesium, and vitamins C and D are also essential for energy.


Before taking any new supplements, you should always check with your GP if you think you may be suffering from the symptoms of a vitamin deficiency.

Which vitamin deficiency causes fatigue?

Vitamin deficiencies aren’t as uncommon as you might think, especially here in the UK.


It is estimated that one in 5 adults and 1 in 6 children in the UK have low vitamin D levels, symptoms of which may include tiredness and fatigue. 

Another vitamin deficiency that can cause fatigue is iron deficiency anaemia, which is particularly common in vegans, vegetarians and menstruating women.


If you’re experiencing any symptoms of a vitamin deficiency, you should speak to your GP so they can issue a blood test to identify the exact problem.

Does vitamin C give you energy?

One of vitamin C’s many important roles in the body is converting food and drinks into energy and helping to absorb other vitamins and minerals.


If you need a boost, taking a vitamin C supplement or eating a diet rich in vitamin C sources might help your energy levels, alertness and focus.


Good sources of vitamin C include citrus fruits, peppers, broccoli, strawberries, brussels sprouts and potatoes.

Can vitamins interfere with sleep?

If you’re taking vitamin D too close to bedtime, it may affect your sleep quality, as high amounts of vitamin D in the body may interfere with the production of melatonin.


However, other studies suggest that having a low amount of vitamin D in your body may lead to a higher amount of disturbances, and reduced sleep quality and duration.


It’s probably easier to take your vitamins along with your morning meal, but until there is concrete evidence, experiment and find a routine that works best for you.
