Help tackle fatigue and tiredness with these Holland & Barrett B12 tablets

Even if you get a solid 8 hours sleep a night, exercise regularly and feel like you’re living a healthy lifestyle, tiredness and fatigue can sneak in and make you feel listless, and there’s nothing more frustrating! Give yourself a break – it’s not always your life choices that make you tired; fatigue and tiredness could have a lot more to do with what your put into your body, or in the case of vitamin B12, what you don’t put in your body.

A very important vitamin used for multiple functions in the body, vitamin B12 is essential for maintaining a healthy and normal energy-yielding metabolism. This helpful vitamin, also known as cyanocobalamin, also contributes to healthy psychological function, nervous system function and can help reduce tiredness and fatigue.

Vitamin B12 can be found naturally in animal products like meat and dairy, as the animals obtain it from the soil or are often supplemented with it themselves. You can also find it in fortified vegan food like plant milks, breakfast cereals, fake meats and yeast extracts. However, quite a lot of people find themselves deficient in B12 - you may be susceptible to low vitamin B12 status if you follow a vegan or plant-based diet - and long-term deficiency symptoms can be very severe and sometimes dangerous.

What are the benefits of vitamin B12?

Vitamin B12 supports normal energy-yielding metabolism: when vitamin B12 starts to drop, your energy levels tend to follow suit. Providing your body with enough vitamin B12 will help your body have the energy to tackle any day.

Vitamin B12 supports red blood cell synthesis: red blood cells help to deliver oxygen to all of our body tissues. The body needs vitamin B12 to make red blood cells.

Vitamin B12 supports healthy nervous system function: good levels of vitamin B12 help to keep your nervous system nice and healthy.
