Vitamin B is a group of water-soluble nutrients that play a central role in how the body converts food into energy. Found naturally in a range of foods, most are obtained regularly from the diet, though how much is stored varies by nutrient. Vitamin B12 contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue, and vitamin B6 contributes to normal protein and glycogen metabolism. This range covers the full B vitamin family, from individual options to combination formulas, from brands stocked in our pharmacy. Whether you're looking for folic acid, B12, or a complete B complex, browse the full range below. Follow the dose on the pack and do not exceed it: some B vitamins, including vitamin B6, have upper intake limits, so ask our pharmacist before taking high-strength products. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
Vitamin B12 contributes to normal energy-yielding metabolism, to normal red blood cell formation and to the normal functioning of the nervous system. Different B vitamins have specific roles — for example, vitamin B12 and folate have a role in the process of cell division, while vitamin B6 contributes to normal protein and glycogen metabolism. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
A B complex typically combines several B vitamins in a single tablet, which suits people looking to support overall intake in one go. Individual supplements — such as standalone B12, B6, or folic acid — allow you to target a specific nutrient at a higher dose. Your choice depends on whether you have a general gap or a particular need.
B vitamins play a central role in converting food into usable energy at a cellular level. They help the body metabolise carbohydrates, fats, and proteins. Vitamin B12 contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism. Tiredness has many possible causes, so if it persists, speak to your GP.
Follow the recommended daily dose on the pack and do not exceed it. Some B vitamins, including vitamin B6, have upper intake limits, so take care when combining products or choosing high-strength options. Some formulations are made for once-daily use, including time-release options. If you are on medication or have a health condition, it is worth checking with a pharmacist first.
The HSE advises women who could become pregnant to take folic acid daily, and folate contributes to maternal tissue growth during pregnancy. Other B vitamins, such as B12, also contribute to normal cell division. Pregnant women should follow guidance from their GP or midwife regarding which supplements and doses are appropriate for their individual circumstances.
