Hi there,
I have had palpitations since my 30’s and hot flushes after a total hysterectomy 10 years ago, not allowed hrt because of endometriosis. Have found that taking 2 tablespoons of ground flaxseed and 1-2 tablespoons of chia seed a day greatly improve my symptoms. I put it in porridge or make a sort of pudding out of it with hazelnut milk ( add milk and leave it in fridge for a couple of hours to swell up). Then I add nuts, honey, fruit or cocoa powder to it. It’s a bit gloopy like tapioca but I love the taste now.
Also use olive oil for cooking as my only oil, all this adds omega 3’s which are supposed to help.
