Stress, aging, active lifestyles, poor digestion, alcohol consumption, PMS, menopause, and cardiovascular disease are just some of the factors that increase the body’s need for B vitamins. Inadequate intake of some B vitamins is not uncommon and deficiencies can be associated with fatigue, insomnia, depression, and migraines. In the diet, B vitamins are found in yeast, green leafy vegetables and lentils. The best sources of B12 are meat and seafood, making supplements particularly advisable for vegetarians.
Although each B vitamin has a unique role, they work together as coenzymes to metabolize proteins, carbohydrates and fats and to provide the body with energy. B vitamins help synthesize brain chemicals which support mood and nerves. They are essential for healthy skin, hair, eyes, mouth and liver and as they are water-soluble, B vitamins are not stored in the body and must be replenished daily.
