As someone who has suffered from candida for over 2 years I have Threelac for 2 years in combination with Thyme Formula and Wild Endive Formula
I much prefer the capsules to the sachets and found them to be just as effective. I took 2 capsules twice a day.
Taken regularly I have much less vaginal thrush which used to be a major problem for me. I also found it helped with my acne which is much better.
I did try Fivelac for a few months some time ago but did not feel that this was any more effective.
I usually feel really ill in the Autumn as I react to atmospheric moulds. Last year I had very little reaction which I attribute to Threelac taken regularly as I had not changed anything else.
As the combination of products have curbed rather than cured my candida problem I am now trying other products, but would definitely recommend using Threelac.
I would also recommend booking a consultation with Mark Lester at The Finchley Clinic if after 12 months or so your symptoms reappear when reducing products, as you may benefit from trying a different regime. His advice has certainly helped me.
