Ginkgo Biloba

One of the world's oldest tree species with leaves that improve blood circulation to the brain. Used for memory and cognitive function.

What is Ginkgo Biloba?

Ginkgo Biloba, also known as ginkgo or the maidenhair tree, is one of the world's oldest tree species and has existed for over 200 million years. It is a unique species often used in traditional medicine and health supplements. Ginkgo Biloba extract comes from the leaves of the tree and is popular for its purported benefits for memory and cognitive function. Many people turn to Ginkgo Biloba to improve concentration, reduce symptoms of anxiety, and enhance blood circulation, especially to the brain.

How does it work in the body?

Ginkgo Biloba is believed to work by increasing blood flow to the brain and other parts of the body. The active compounds in Ginkgo Biloba, primarily flavonoids and terpenoids, have antioxidant properties that may protect cells from damage caused by free radicals. By improving circulation, Ginkgo Biloba can help enhance oxygen and nutrient delivery to brain cells, which in turn may support cognitive functions and memory capacity.

Scientific benefits

Several studies have investigated the effects of Ginkgo Biloba on cognitive function and memory. A review article published in the Journal of Psychopharmacology showed that Ginkgo Biloba may have a positive effect on memory in older adults with dementia or mild cognitive impairment. Another study in Psychological Science demonstrated that Ginkgo Biloba extract can improve working memory and attention in healthy individuals.

  • A 2015 meta-analysis summarised that Ginkgo Biloba may have a small but significant effect on cognitive function in older adults.
  • Several studies have also suggested that Ginkgo Biloba may help reduce symptoms of anxiety and depression, which can have an indirect positive effect on cognitive functions.
  • According to research published in Current Neurovascular Research, Ginkgo Biloba may have neuroprotective effects, meaning it can protect brain cells from damage.

Dosage and recommendations

The recommended dose of Ginkgo Biloba varies depending on the form and concentration of the extract. Generally, a dose between 120 mg and 240 mg per day is recommended, divided into two to three doses. It is important to follow the instructions on the product label and consult a physician before starting supplements, especially if you have underlying medical conditions or are taking medications.

Best sources and forms

Ginkgo Biloba is available in several forms, including:

  • Capsules and tablets: These are the most common forms of Ginkgo Biloba and provide precise dosing.
  • Liquid extract: Offers faster absorption, but dosing can be more difficult to measure.
  • Tea: Ginkgo Biloba tea may be a milder form but usually contains lower concentrations of active compounds.

When choosing Ginkgo Biloba, it is important to select high-quality products from reputable manufacturers that offer third-party testing for purity and potency.
