There are 8 vitamins in what is known as the B vitamin complex, B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate or folic acid), B12 (cobalamin). The B vitamins can all be found in the diet, mainly in cereals, legumes, meat and eggs, however they aren’t always that well absorbed and utilised, making supplementation a convenient way to ensure you are getting enough.
Although deficiencies are not that common, people with liver, kidney, digestive or autoimmune diseases, as well as smokers, obese people, alcoholics and pregnant women may find themselves low in some B vitamins.
If you want a tangible and noticeable improvement in energy, B- vitamins can often help. B- vitamin complexes enable a variety of enzymes to do their jobs including releasing energy from carbohydrates and fat, to breaking down amino acids and transporting oxygen and energy-containing nutrients around the body.
When combined in optimal form and dosing, a Vitamin B complex can contribute to a reduction in tiredness and fatigue, support normal energy-yielding metabolism, normal psychological function and support the normal functioning of the nervous system.
