Got questions? We’ve got answers!

Are KOS products certified organic?
Nearly every ingredient is certified organic and therefore free of hormones, antibiotics, pesticides, artificial sweeteners, colors, and GMOs. When you check out the ingredient panel of our labels, you’ll see “organic” in front of the specific ingredients that are certified organic.
What if I purchase and don’t like it?
We stand behind the quality of our products and want to make sure our customers are completely satisfied. Your satisfaction is guaranteed for a full 90 days from the date of purchase.
Is KOS tested for heavy metals?
Yes, all KOS products are thoroughly screened for a full spectrum of contaminants, including heavy metals. KOS protein contains more than a dozen ingredients, each of which is subjected to an individual screening—as is the whole of the batch—in both pre- and post-production phases. This full-spectrum screening for contaminants and heavy metals is managed in strict accordance with USDA Organic and CCOF compliance standards.
Where is KOS made?
Our formulas are made in sunny Southern California, and the ingredients are certified by the United States Department of Agriculture (USDA) and California Certified Organic Farmers Association (CCOF).
