Vitamin E– this often vilified nutrient is very important for brain and moods. But never use the synthetic versions as that has been linked to cancer and heart disease. This is a family of eight antioxidants known as tocopherols (alpha, beta, gamma, and delta) and tocotrienols (alpha, beta, gamma, and delta) that protect fat. Vitamin E protects the fats in our brain from free radicals, especially the omega-3 fats DHA and EPA, which are concentrated in neurons. Aside from protecting your neurons, natural forms of Vitamin E are also linked to the prevention of cancer and protection from heart disease.
