Yes I think microbz Women is a good choice - its good to focus on the health of the whole gut and hormonal balance as everything in the body is linked. Also helpful is a diet to minimise over-growth and caprylic acid from coconuts is particularly good against candida over-growth.
You can take microbz orally, but you can also swab the vagina with it and as this is a slightly acidic environment for most of the month that's fine regarding the ph balance.
Make sure you are wearing natural fibres and very gentle natural products and also filtering your drinking water.
