For real, is THreelac useful or could trying it do harm?

So now I feel stupid. I am week three on my candida diet and have been regularly changing my anti fungels to keep any tolerance from occurring and read an article on Threelac and jumped on board. I have had great success with M****tech which is also a pyramid scheme so I thought it might be worth the risk. But then when the stuff arrived in the mail it tasted really sugary and now I am wondering did I just blow forty bucks? Does it have any benefit?
Please let me know. I am worried that all my hard work could be lost.
Thank you
