Inositol questions

Hi everyone, I’d like to understand a bit more about Inositol. I’ve started taking Wholesome story Myo & D-Chiro inositol once a day. (2000mg) and am considering upping to 4000mg. I’ve taken it for about a month, and am not noticing any difference at all.

My Q’s are:

• If I up my dosage do I take it all at once, or twice a day eg. Breakfast and dinner?
• How long until you noticed any form of difference? (at your most helpful dosage)
• I’ve seen people taking more than 4000mg/day - wondering how you came to that conclusion and what dosage you take? (Just wanting to learn & hear others experiences)
• do you take any other supplements?
• What do you look for and how do you know you’re taking a good quality Inositol? There is such a vast difference in price between brands and I’d really like to try a less expensive brand (especially if I’m doubling what I take currently!)

(For ref, I’m in Australia)

Thanks,
