Don't waste your money on threelac!! The best probotic is from home-made kefir. It costs nothing. I also used Nature Secret's Ultimate probiotic. It is very good. I rotated these antifungal every 2-3 weeks, they are capryilic acid, olive leaf extract, grapefruit seed extract, candidstoy, and Clarkia ( parasite cleanse). I used fresh raw garlic instead of tablet. I dont know what 'oxygen element' is, but wouldn't it be better if you spend your money on a ozonater instead of supplement?? do a search on ebay, you will always find an affordable one. The one I bought costs USD 60.
To be honest, if you follow a strict candida diet, take antifungal, introduce good bacteria back into your body and you need vitamins like B3-6-12, Biotin to help to repair the damage. you don't need to spend too much money.
To me, Strict diet and kefir made such a different in fighting against candida.
