Whether that means more energy or better focus, there are multiple options in the supplement market advertised for those benefits.

Here are three of the most popular supplements recommended for productivity and their possible side effects:

1. Acetyl-L -carnitine: ALCAR is an amino acid that some studies show improves flow of blood to the brain. It is naturally produced in the body and works in many of the body's processes to increase energy. According to WebMD, although rated as "likely safe," it can cause some uncomfortable side effects such as nausea, vomiting, and restlessness.

2. Dimethylethanolamine: This chemical, called DMAE, is involved in how acetylcholine functions in the body. While promoted as a product to help with ADHD and Alzheimer's symptoms there is insufficient evidence to show that it helps with memory, intelligence, and physical energy, according to WebMD. DMAE is found naturally in anchovies and sardines. There is concern, however, that it may interact and make depression and schizophrenic symptoms worse. It may also increase blood pressure, cause confusing dreams, constipation, headache, itching, and drowsiness, among other symptoms.

3. Ginkgo biloba: This herb is one of the most widely used in the world, touted for helping with memory loss, depression, eye diseases, and many others. Although the leaf extract is considered safe when taken by mouth, some concerns have been raised that it has caused liver and thyroid cancers in animal studies when given high dosages, according to WebMD. "There is some concern that ginkgo leaf extract might increase the risk of bruising and bleeding. Ginkgo thins the blood and decreases its ability to form clots. A few people taking ginkgo have had bleeding into the eye and into the brain, and excessive bleeding following surgery. Ginkgo leaf extract can cause allergic skin reactions in some people."
