Always Tired? Best 5 Supplements To Beat Extreme Fatigue


Keeping up with a regular exercise plan is hard and many of us have the greatest of intentions. We think that in order to make up for a missed session on a Monday evening, we will do three or four lunchtime sessions with a personal trainer to ensure our plan is completed… Sound familiar?

Our days just got a little busier in finding time for our HIIT workouts as we both work and play in the gym. So how do you keep your eyes open as the blanket of fatigue sets in and gets you a cosy chair away from an early night’s kip at 8 pm?

Beat extreme tiredness and get a much-needed energy boost with some highly beneficial supplements…


1. Vitamin B12


If you search for “how to prevent fatigue” in a textbook or on the internet, Vitamin B12 will always come up!

Vitamin B12 is a water-soluble vitamin which has its effects predominantly on the actions and functions of the brain and nervous system.

One study examined the benefit of vitamin B12 injections over 2,000 people. They did not find any positive effect until they increased the dosage to 2,500-5,000mg every 2-3 days. However, when they did they found that between 50-80% of people found an increase in energy and stamina with 2-3 weeks (2-3).

The use of this vitamin to reduce pain has also been examined in people with back pain (4), nerve pain (5) and even cancer! (6).

Vitamin B12 seems to show good levels of improvement with fatigue –  If your fatigue is related to an injury or pain from an underlying issue, you could consume a fair amount of this supplement as a secondary painkiller.

2. Vitamin C

This is another vitamin commonly discussed and taken by a large number of individuals and which has lost its proper chemical name! Also known as L-ascorbic acid (or ascorbate), Vitamin C is involved with a large number of reactions, particularly with wound healing and as an antioxidant.

Vitamin C has also been somewhat effective in reducing the duration of symptoms when you get a common cold (7-8).

Vitamin C

It has also been found that vitamin C supplementation of 1-3g daily improves our immune system efficiency to counteract bacteria and viruses we come into contact with (9).

Other benefits from consuming more vitamin C are a reduction in delayed onset muscle soreness following strenuous exercise (10), and a reduction in pain comparable to that seen previously with vitamin B12 (11).


Supplement choice: Myprotein Vitamin C powder


If you feel your fatigue is a cold brewing, or if you have been exposed to an environment rife with germs (a long haul flight for example), then a boost of high dose vitamin C may be just the thing to re-gain your energy!

3. Magnesium

Let’s focus on a specific mineral which may assist our fight against fatigue…

Magnesium is a mineral which assists the crucial functions of our blood pressure and cardiovascular system.

The release of stress hormones as a result of a hectic and demanding life can promote a state of magnesium deficiency in our body’s tissues (12). Shockingly, it has been found that up to 15% of Western populations have a reduction in this mineral (13).

In a study examining the benefits of magnesium supplementation in those diagnosed with chronic fatigue, shown that 50% of this patient group were magnesium deficient (14).

100mg doses of magnesium intramuscular injections weekly for 6 weeks showed an improvement in symptoms in 80% of individuals. Only 17% of a parallel group improved with a placebo injection (15).


Supplement choice: Myprotein ZMA, Myprotein Magnesium Citrate


If your daily schedule finds you stressed and anxious and this coincides with bouts of extreme tiredness you may want to consider a magnesium supplement. Keep the dose per day approximately 200-600g to prevent using a sub clinical dose. If you do not benefit over 1 month, then perhaps you are not magnesium deficient!

4. Folic Acid

Also known as Vitamin B9 or folate, this substance is a synthetically produced compound which can be taken in tablet form.

The human body needs folate in order to allow specific biological reactions to sustain an effectively working brain!


Deficiency of this vitamin has been seen to lead to symptoms of:


✓ Confusion

✓ Depression

✓ Immune system insufficiency

✓ Other signs of reduced brain function (1).


These signs can easily be found with general mental fatigue, with loss of memory, confusion and poor reaction speed just a few examples.

Tired all the time? In a study of individuals demonstrating such signs and with easy fatigability, it has been found that a high dose of 10,000mg of folate daily causes reduction in these symptoms.


Supplement choice: Myprotein Energy Effervescent Tablets


If you have a fuzzy head when you’re suffering from extreme fatigue and this has been a long term issue- think about a high dose of daily folic acid to clear your mind. It won’t happen over night but will pay dividends in the end!

5. Caffeine

Caffeine is a powerful stimulant of the nervous system which is readily absorbed by the body and easily crosses the brain barrier to act on various parts of the brain (17). It also alters heart rate, respiratory rate and metabolic rate (16).

The compound is found in coffee, tea, chocolate, carbonated drinks and confectionary in addition to being the most prominent energy boosting ingredient in most if not all pre-work out supplements!


Caffeine seems to improve a number of physical and mental functions by giving us a temporary boost in energy. The improvements noted from consumption of a caffeine supplement include:


✓ Working as an endurance aid (18)

✓ Greater speed of reaction time (19)

✓Increased mental alertness to reduce fatigue (20)


Supplement choice: Myprotein caffeine powder, Myprotein caffeine Pro


If you need a quick fix in fighting fatigue then use of caffeine 60 minutes prior to exercise can be helpful (21).  If your fatigue is deeper rooted than simply not enough energy to get your self to the gym, try adding something else.

Take home message

The key thing to consider when attempting to use supplements to manage fatigue is to identify why you are likely to be having these symptoms.

What is making you so tired?

Do you suffer with a fuzzy head? Confused and dopey when tired? Maybe Folic acid is the way to go.

Is it a virus? Think Vitamin C or Zinc.

Are you too stressed? Magnesium may be your answer.

Training too hard? Consider l-carnitine or co-enzyme Q10.

Need a quick fix? Caffeine is the best option.
