Welcome Rachal and a very good response to your Headache. One item I always think about for this condition is the likelihood of heavy metals like Mercury, Aluminum, Lead, Cadmium, and Arcenic. As one ages small amounts of these accumulate in the body and the organ most affected is the brain which can be the cause of degenerative mental conditions like Alzheimers & Parkinsons. There are Heavy Metal Cleansing remedies here on E.C. which should be done periodically for everyone in the industrial society. Another possible underlying issue is infection in the gut which causes leaky gut which always causes headaches. Oil Of Oregano Softgels is a good start for possible gut infection, but you may wish to take a Candida questionnaire to identify your likelihood.
But for immediate brain health I will list several nutrients or herbs which are very good. Taurine and Acetyl L-Carnitine help detoxify; The herbs Chinese Skullcap, Ginkgo Biloba, and Hemp Oil/CBD are excellent; Coconut Oil and Fish/Krill, Flax, Borage, and Evening Primrose Oil are all good for total body/brain.
