Recommended garlic dosage?

Hi all. Can't believe I've only just stumbled over this site. What a great forum Hope to obtain lots of helpfull info and reply in kind when I can.

In the past year or so I've come to realise that 8 years of Antibiotic use for Acne is the root cause of my problems, mainly my ongoing battle with Acne (better since I've adopted a healthier lifestyle, but can't quite kick it) and alopecia.

My first question is what is the recommended dosage of garlic as an antifungal? I'd rather take it in tablet form and add raw garlic to my food when I can.

I've been taking Caprylic acid with psyllium husk for a month now and wish to alternate antifungals.

Cheers.
