Top 5 Health Benefits and Good Sources of Vitamin B8


Vitamin B8 or Inositol, as it is often called, contributes to the normal functioning of cells in our body. Vitamin B8 is present in various forms. The vitamin is also available with the names IP6 or myo-inositol. It is water soluble and is found in the brain, liver, heart, spleen, stomach and kidneys.

Benefits of Vitamin B8

1.Effective in weight loss

At the cellular level, B8 assists in efficient breakdown of fats and transport lipids from the cells. This in turn activates the body metabolism, leading to weight loss. Inositol also improves the levels of good HDL cholesterol, which channels smoother flow of blood through arteries.

2.Controls hypertension

B8 keeps blood pressure in check, because of effective blood flow via arteries. The contribution to mood management also tackles the causes of hypertension in the individuals.

3.Helps deal with depression, other psychological disorders

Because of its effective responses on neurotransmitters, inositol triggers the production of serotonin, a vital transmitter that controls moods. Studies have been conducted over a period of time on Vitamin B8’s effect on serotonin, thereby, helping with tackling psychosomatic and psychological disorders such as depression, panic disorder and bipolar. Though not completely, intake of inositol has brought superior results in the subjects who have consumed it.

4.Provides relief with PCOS

Women inflicted with Polycystic Ovarian Syndrome (PCOS) can now try Vitamin B8 for potential relief. PCOS is a result of hormonal imbalance that leads to increase in production of male hormones in women, leading to weight gain, infertility, ovarian cysts and erratic menstrual cycles. Intake of inositol has shown significant relief from the condition, as the vitamin enables increased ovulation and weight loss. Some healthcare providers recommend D-chiro-inositol as an effective treatment for PCOS.

5.Improves cognitive function

Because of the massive contribution to better working of neurotransmitters, inositol proves helpful in improving cognitive function. There have been reports of better thought process and active lifestyle after the intake. This effect is partly due to the fact that Vitamin B8 has mood enhancing properties.
