Supports emotional wellness, behavior and mood
Promotes healthy ovarian function
Inositol is a part of the B-complex family. Myo-inositol is the primary form of inositol found in the central nervous system and plays an important role in cell membrane formation. It serves as part of the phosphatidylinositol second messenger system, supporting serotonin, norepinenephrine and cholinergic receptor function. As a result, inositol may support healthy mood, emotional wellness and behavior, and help lessen occasional nervous tension. Research also shows that myo-inositol helps to support healthy ovulatory activity, ovarian function, and reproductive system function.

Myo-inositol in the Treatment of Mood and Behavior Disorder
According to a study performed in Israel (1): "These results suggest that inositol has therapeutic effects in the spectrum of illness responsive to serotonin selective re-uptake inhibitors, including depression, panic and OCD, and is not beneficial in schizophrenia, Alzheimer's ADDH, autism or ECT-induced cognitive impairment."
The doses of inositol used in the Israeli studies ranged from 12 to 18 grams of inositol daily with significant improvements noted after 4 to 6 weeks of treatment with inositol.
Myo-inositol in the Treatment of PCOS-related Infertility and Non-PCOS Egg Quality Infertility
Myo-inositol has been widely studied and found effective for PCOS-related causes of infertility and some non-PCOS egg quality improvement. These have all been human studies. In fact, myo-inositiol is one of the better-studied agents for this purpose.
Inositol is part of the vitamin B complex. It occurs as 9 different isomers, but only two of these are of interest in fertility:
myo-inositol (MYO) and d-chiro-inositol (DCI)
Both MYO and DCI have been studied and found useful in the treatment of PCOS.(1-14) However, only MI has been show to be present in follicular fluid and only MI was able to improve oocyte and embryo quality (1,2,9,12,15), ovulation induction (6-8,10-11) and hormone balance. (3-5,13) DCI does not have even remotely as much research behind it as MYO. (16) Therefor, for fertility issues with or without PCOS, I recommend the myo-inositol form. Please note that some of these studies used melatonin in combination with myo-inositol (2,11-12). Melatonin alone has also been studied and found useful for improving egg quality. (17-18)
Myo-inositol may also improve other associated risks of PCOS (sugh as high triglycerides and blood sugars) with or without an effect on egg quality. (3,5,7)
Most forms of inositol available in health food stores are probably the myo-inositol form. However, many products do not specify this on the label. I would always want to verify with the manufacturer before using.
A product called "Pregnitude" is available, containing myo-inositol plus folic acid. Several studies used myo-inositol with folic acid and found improved egg quality in PCOS. (9,11) All pre-pregnant women should already be getting folic acid from their multiple because of it's importance in preventing spina bifida. This makes the "magic" in Pregnitude the myo-inositol. Pregnitude is individually packaged by 2 gram serving, and that is convenient, but the price is double what what most myo-inositol powders are.
Daily dose of myo-inositol for improving egg quality is 2-4 grams per day. This can be taken as 2 grams, once or twice daily.
Myo-inositol product has a mild sweet taste and can be taken in water, smoothie, Super Shake --- whatever makes it easiest.
Egg Quality Protocol, Especially for PCOS Patients (Dr. Myatt's recommendation based on the studies)
I.) myo-inositol: 2-4 grams per day
II.) melatonin: 3mg per day (take this at bedtime)
III.) folic acid: 400mcg (this amount or more should already be in a good multi-vitamin. Maxi Multi contains 800mcg of the natural form of folic acid, tetra-methyl folate)
