Herbs and Supplements for Brain Health

November 23rd, 2018 | Posted in Uncategorized

With brain ischemia and neurodegenerative disorders, such as Alzheimer’s and Parkinson’s, being on the rise worldwide there has been an upsurge in interest into the beneficial effects of plants and traditional medicines on brain health. Herbs, spices and other plant foods have many therapeutic properties including antioxidant and anti-inflammatory compounds that may benefit brain function  (1). Unlike conventional drugs plant derivatives tend not to have undesirable side effects (2). That said, they can have powerful effects and should be treated with respect.

Here are some herbs and supplements that may be useful for protecting the brain and improving cognition:

  • Flavonoids from plant foods such as curcumin from turmeric, lycopene from tomatoes, ginsenoside from ginseng, along with many others, have a range of neuroprotective effects making them useful therapeutic agents in brain disorders (3).
  • Rosemary is rich in antioxidants such as rosmarinic acid which has important neuroprotective effects (4). Rosemary oil is reputed to aid memory.
  • Ashwagandha has long been used in Ayurvedic medicine to improve memory. Modern research confirms that it may indeed have beneficial effects in those with cognitive decline or Alzheimer’s disease (5).
  • Ginkgo biloba has been found to increase circulation to the brain and may improve cognitive performance in females (6).
  • Alpha Lipoic Acid protects neurons and inhibits oxidative stress and inflammation (7).
  • Acetyl-L-Carnitine is neuroprotective in a number of ways including having anti-inflammatory, antioxidant, analgesic and anti-depressive properties (8).
  • EPA, DHA and Vitamin D – these nutrients work together to improve brain function through the serotonin pathway (9).
