The majority of my supplements are from Gaia Herbs. Quality brand with clean organic ingredients. I most commonly use their Liver Cleanse, Resveratrol, Vitex Berry, Women's Balance, Plant Force Liquid Iron, Oregano Oil… I have seen instant benefits in using the required dosage in minimal time. Some of their supplements don't have a taste while others might leave an aftertaste, it all depends on the herbal composition of the product. The Quick Defense along with the others listed on this review have greatly helped me manage my peri-menopause. Very grateful to this brand.
