There's definitely a lot to consider and choose from, and it can come down to choosing science-backed approaches or marketing hype. I recommned the Candida Plan - www.candidaplan.com. The Plan has been around for over 20 years with great results. Here are some posts that offer more information on various approaches:
Part I: Candida and Medications
Part II: Candida and Hydrogen Peroxide
Part III: Candida and Bacillus subtilis
Part IV: Candida and Sugars
Part V: Candida and The Quick Fix
Part VI: Candida and Herbs
Part VII: Candida and Probiotics
Part VIII: Candida and Fatty Acids
