Benefits of Inositol Powder

Inositol powder is used to help with a variety of quite important bodily functions. Its natural roles in the body include providing cellular structure, helping maintain insulin production and facilitating chemical messages in the brain.

Mental Health

It may play a role in producing the hormones serotonin and dopamine. Dopamine is the chemical that stimulates the reward center of your brain, to make you feel happy and serotonin is another “feel-good” chemical that aids in social interaction and feelings of contentment. Some studies show that low myo-inositol concentrations in the blood may indicate a higher risk for depression. In a study of people with panic disorders, Inositol’s use significantly reduced the number and intensity of panic attacks. Overall, Inositol is an excellent supplement for supporting cognitive function.


Its relationship with serotonin may also help promote better quality sleep and address symptoms related to insomnia. Serotonin naturally encourages calm and peaceful sensations that can help induce sleep. Studies point out that an alarming amount of adults experience sleep deprivation or low quality sleep, which may increase the risk for further health issues, including chronic fatigue and trouble with memory and concentration. Inositol may be a helpful tool for combatting this. However, there are no studies stating that inositol can definitely cure any mental health condition.

Insulin Resistance

Inositol naturally helps support heart health because of its role on blood sugar and insulin regulation. Insulin resistance is how the body responds to insulin and contributes to metabolic syndrome, a group of conditions that can increase the risk for heart disease, stroke and type 2 diabetes. The body uses inositol to produce molecules that support insulin regulation, so it may benefit insulin sensitivity.

In a study published in the Journal of International Medical Research, it was found that supplementing it in combination with a calorie-restricted diet significantly improved weight loss compared to a calorie-restricted diet alone.

Reproductive Health

Its effect on insulin regulation may also have an effect on reproductive health, specifically with polycystic ovary syndrome (PCOS), a hormonal imbalance that can occur in the ovaries, disrupting the body’s ability to produce and release eggs. It can cause irregular periods, cysts and infertility. Studies state that patients with PCOS may often have high insulin levels.
