Holland & Barrett Vitamin B12 250µg Spray is designed to help reduce tiredness and fatigue, support normal energy-yielding metabolism, and is suitable for both vegetarians and vegans. Vitamin B12 plays a crucial role in supporting various bodily functions, including the normal production of red blood cells and the release of energy. It helps alleviate feelings of tiredness and fatigue while supporting a normal energy-yielding metabolism. Key sources of Vitamin B12 are animal-based products such as meat, fish, milk, cheese, and eggs, which can make it challenging for vegans to meet their B12 needs through diet alone. If you find that you're not consuming enough of these foods, a Vitamin B12 supplement might be necessary. Holland & Barrett Vitamin B12 supplement comes in a convenient spray form that is easy to use and quickly absorbed. Simply spray it into your mouth, either on your tongue or inner cheek, and you're done!
