A. While D-Limonene was formulated to be taken every other day, it can be safely taken daily as well.

A. No, D-Limonene must be swallowed whole. We do not recommend opening the capsules and mixing the contents with food or liquids as the volatile oil in this product could irritate the throat.

A. Although the D-limonene found in D-Limonene is 98.5% pure, because it is from citrus fruit peel, it is possible that it may contain some citric acid. This amount should be very small and is unlikely to cause irritation except in those who are extremely sensitive.

A. Limonene is a chiral molecule. That is, it exists in two forms as mirror images (e.g., human hands are an example of chirality). Most chiral molecules are found in one form in nature, and D-limonene is the naturally occurring form of limonene. We are not aware of any synthetic limonene preparations on the market as D-limonene is found in citrus fruits and a variety of other plants. Furthermore, the compound is a terpene and is not particularly easy to produce synthetically.

A. No, D-limonene is not recommended for individuals who have ulcers or suspect they have ulcers. D-limonene can irritate an open wound and result in a burning sensation.
