NOW Candida Support by NOW Foods enjoys hundreds of 5-star reviews from satisfied customers who used to be afflicted with candida overgrowth. Its effectiveness results from ingredients such as oregano oil powder, caprylic acid, and pau d'arco, which is derived from the inner bark of Tabebuia trees. It's a big part of traditional medicine in South and Central America, and is known for its candida-fighting properties. Black walnut, another ingredient, has a long history as a yeast infection remedy.

Owned by the Richard family, NOW Foods entered the natural products industry in 1968. Today, it operates high-tech laboratories as well as manufacturing and distribution facilities in the USA and Canada.

This is a high-quality product from a reputable company, but the lack of the super ingredients reishi mushroom and anise seed extract, as well as probiotics such as L. acidophilus is a big point against it. Moreover, potential side effects such as dizziness, nausea, and vomiting—which have been experienced by many users—are causes for concern.
