Inositol is a very safe food supplement. It is naturally found in mothers breast milk and often used in infant formulas and baby foods.
For a small percentage of women there is an adjustment process. This may mean headaches, dizziness, stomach ache or more frequent urination for the first few days or even weeks.
If this is the case for you, then we recommend you take your regular over the counter headache tablets and or start on a smaller dose and build up to the recommended dose slowly.
So rather than 4 grams per day you might take 1g in week 1, 2g in week 2, 3g in week 3, 4g in week 4.
It may also be helpful to split the daily dose into a morning and evening serving.
If problems persist stop taking inositol immediately and talk to your GP.
