Vitamin B is one of the most beneficial vitamins as it’s involved in almost every metabolic process in the body. Vitamin B plays an important role in the release of energy from foods, the normal functioning of the immune and nervous systems and the regulation of hormonal activity. Many foods contain vitamin B and with a varied diet you should be able to get all the nutrients you need, however if you need a boost there are many types of vitamin B supplements you could try. Please note you should not take supplements as a substitute for a varied balanced diet or a healthy lifestyle. Always read the label. Ask your local pharmacist for advice.
