Curcumin dietary supplements containing curcumin root extract are another form of curcumin intake. Supplement labels will indicate different percentages of curcumin extract. Independent quality control and quality assurance laboratories test and inspect the product to verify these claims and endorse the label as directed by the manufacturer of the product. Some curcumin dietary supplement formulations may also contain other extracts, such as black pepper extract (piperine) or proprietary mixtures containing vegetable gums, or other lipid preparations, in an attempt to improve the bioavailability of curcumin. In particular, research has shown that curcumin can be used as a topical agent in formulations of collagen films, lotions, sponges and bandages to promote healthy skin.

Crushed red pepper factories are responsible for processing and packaging the dried and crushed fruits of the Capsicum annuum plant, typically the cayenne pepper variety. These peppers are harvested when they are fully ripe and have developed their signature spicy flavor. The peppers are then dried and ground into flakes or powder, which are then packaged and sold to consumers.
