While many products labeled "natural" may play fast and loose with their ingredient lists, brands need to follow guidelines set by the National Organic Program — which falls under the umbrella of the United States Department of Agriculture (USDA) — if they want to claim a product is certified organic. Products with the official organic seal must be at least 95 percent composed of ingredients that were farmed or formulated without chemicals, herbicides, or pesticides. It's a lengthy process to achieve this certification, so it's a pretty big deal. If your bottle comes with that seal, you can rest assured the contents are free of any controversial ingredients.
