Low Energy? Can’t Focus? Here’s Why B12 May Be To Blame


Feeling low on energy or struggling to stay focused? You may have a vitamin B12 deficiency. Let’s dig a little deeper into this powerhouse vitamin whose absence may have you lacking get-up-and-go.

Vitamin B12 is crucial for our heath. And although it is an essential vitamin used in several important body functions such as making red blood cells, converting food to energy, and keeping the nervous system healthy, our bodies do not naturally produce it; which may seem strange considering its importance for whole-body health. So, if it doesn’t come from us, where does it come from?

Before the use of pesticides, antibiotics and chlorine in agriculture, people used to get their dose of B12 by eating traces of soil on plant foods or by drinking river/stream water. However, modern farming techniques used to kill bacteria on crops that could otherwise make us ill, also kills the bacteria that produces B12. Now, farm animals receive supplementation to put the vitamin back into the food chain. But with more and more people in the UK reducing their meat consumption in favour of plant-based options plus questions around our ability to absorb B12 from meat, direct supplementation could be the way forward to reduce your risk of deficiency.

Here is everything you need to know:
