- [Coenzyme Q10](/overview/nutrition/nutrients/conditionally-essential/coenzyme-q10.md): Coenzyme Q10 (COQ10) is not an essential nutrient as it is made by our bodies. In fact, all animals can synthesize it. It's also known as ubiquinone, because it's so ubiquitous.

- [Collagen](/overview/nutrition/nutrients/conditionally-essential/collagen.md): Collagen is not an essential nutrient but it is a type of protein. Your body naturally produces it for the construction of connective tissues among other things.
- [Carnitine](/overview/nutrition/nutrients/conditionally-essential/carnitine.md): Carnitine is not an essential nutrient. The body naturally synthesizes its own carnitine from protein. Carnitine is a generic term for multiple compounds.
- [Optional](/overview/nutrition/nutrients/optional.md)
- [Chromium](/overview/nutrition/nutrients/optional/chromium.md): Chromium is not an essential nutrient. It is used in trace amounts by the body, but even complete deficiency in it causes no health issues, so it is not essential.
- [Nickel](/overview/nutrition/nutrients/optional/nickel.md): Nickel is not an essential nutrient. It is used in trace amounts by the body, but even complete deficiency in it causes no health issues, so it is not essential.
- [Antioxidants](/overview/nutrition/nutrients/optional/antioxidants.md): Antioxidants are helpful substances that help protect cells in the body from the damaging effects of oxidative stress caused by free radicals.
- [Phytochemicals](/overview/nutrition/nutrients/optional/phytochemicals.md): 'Phyto' is Greek for 'plant', so a phytochemical is literally a plant chemical. Phytochemicals are typically beneficial for human health, but not essential.
