Green Coffee Bean Extract


Green coffee bean extract is an extract of unroasted, green coffee beans. Green coffee bean extract has been used as a weight-loss supplement and as an ingredient in other weight-loss products. This coffee bean extract was promoted by Dr. Oz, an American TV doctor, back in 2012.[1]


Green coffee bean extracts contain a higher quantity of the chemical chlorogenic acid. This chemical is believed to possess health benefits. For high blood pressure, it might affect blood vessels in order that blood pressure is reduced. For weight loss, chlorogenic acid in green coffee bean extract is thought to have an effect on how the body handles blood sugar and metabolism.[2] Green coffee bean extract may also increase your energy levels in a way that’s almost like how coffee works.[3]
The common health benefits of green coffee bean extracts include:

  • Helps with weight or fat loss [7]
  • Normalizes blood sugar [8]
  • Helps lower blood pressure [9]
  • Acts as an antioxidant [10]
  • Delays aging [11]
  • Enhances energy levels [12]
  • People report it improves focus and mood
  • Improves heart health [13]
  • Benefits brain health [14]
  • Helps people who are fighting Parkinson’s disease, Alzheimer’s disease, and certain types of cancer [15]

How it works

Green coffee bean extract is a powerful supplement since these beans are processed before they are ripe. Their caffeine content is higher than what you’d notice in ripe beans that makes green coffee bean extract a very efficient supplement. [4]
Green coffee bean extract is technically a stimulant, however it only has about 16mg of caffeine per serving! A cup of coffee has about 90mg! Therefore, this is very low, even if you’re sensitive to caffeine. If you’re typically turned off by stimulant supplements, you most likely will not feel any stimulant-effects from it.[5]
Green coffee bean extract also boasts high levels of chlorogenic acid, a polyphenol antioxidant that researchers speculate might promote weight loss by reducing the absorption of fat and glucose in the gut, and lowering insulin levels to boost metabolic function.


Green coffee bean extract contains caffeine which may have various side effects that include anxiety, jitteriness, speedy heartbeat, etc when consumed in large amounts. Some individuals may experience allergic reactions to green coffee beans.[6] Green coffee bean extract has not been shown to be safe for pregnant or breastfeeding women and should not be consumed by children.


Dr. Oz suggested that people take 400 mg three times daily. He suggested taking 400 mg about 30 minutes before each meal, which totals 1200 mg per day. Always check with your doctor, or other licensed physician, before starting any supplementation program including green coffee bean extract supplements with chlorogenic acid.
