Why B Vitamins are central to how your body functions

B complex vitamins have numerous benefits; combining them means you can get your recommended intake without worrying. Here's what Vitamin B can do for your body.

Energy production

Vitamin B Complex converts food into energy, breaking down carbohydrates, proteins, and fats to ensure the body receives the necessary fuel for optimal functioning. If you lead an active lifestyle, you'll need to ensure you get enough Vitamin B.

Nervous system support

B vitamins help maintain nerve cells' integrity and facilitate signal transmission between the brain and different parts of the body. In simple terms, the vitamin is vital for your cognitive functioning and neurological health.

Red Blood Cell Formation

Insufficient levels of Vitamin B Complex can lead to anaemia and related complications. Certain B vitamins, such as cobalamin (B12) and folate (B9), produce red blood cells. These cells carry oxygen throughout the body, ensuring proper oxygenation of tissues and organs.

Boost your health with our Vitamin B Complex

Our Premium formula with all eight B vitamins essential to human health. It offers high energy support for those with busy lifestyles and can make a significant difference to your energy and facilitate normal nervous system functioning.

Packed with goodness, just one Vitamin B Complex tablet will set you up for the day. Each tablet includes:

Thiamine (B1)

Thiamine converts carbohydrates into energy and supports the function of the nervous and immune systems. If you eat a lot of whole grains, legumes, and nuts, you probably get enough of them, but supplements can also boost your intake.

Riboflavin (B2)

Riboflavin facilitates energy production and cellular growth and maintains healthy skin and eyes. Food sources rich in riboflavin include milk, eggs, leafy greens, and fortified cereals.

Niacin (B3)

Niacin is involved in energy metabolism, DNA repair, and the production of various hormones. Vegetarians can vegans particularly need to boost their Niacin intake, as it's in food like meat and fish—but you'll also find it in whole grains.

Pantothenic Acid (B5)

Pantothenic acid is essential for energy production, hormone synthesis, and maintaining healthy skin and hair. Diets high in legumes often get enough Pantothenic Acid, but most people can benefit from supplements.

Pyridoxine (B6)

Pyridoxine is involved in brain development, neurotransmitter synthesis, and the production of red blood cells. Food sources rich in pyridoxine include fish, poultry, bananas, and fortified cereals.

Biotin (B7)

Biotin plays a role in energy metabolism, maintaining healthy hair, skin, and nails, and supporting foetal development during pregnancy. It can be found in foods like eggs, nuts, seeds, and vegetables.

Folate (B9)

Folate is essential for DNA synthesis, red blood cell production, and supporting foetal development. Food sources rich in folate include leafy greens, legumes, citrus fruits, and fortified grains.

Cobalamin (B12)

Cobalamin is involved in the production of DNA and red blood cells and in maintaining the health of nerve cells. It is primarily found in animal-based foods like meat, fish, poultry, and dairy products, an essential supplement for vegans.
