SYNTHETIC VS NATURAL VITAMIN E
Natural vitamin E is known as “d-alpha-tocopherol.” This is the most biologically active form of vitamin E.
Synthetic vitamin E is known as “dl-alpha-tocopherol.” According to the NIH Office of Dietary Supplements, you need “approximately 50% more IU of synthetic alpha tocopherol” to get the same nutritional effect. They are derived from petroleum products.
Fish like Salmon, Trout and other fatty fish contain small amounts of natural Vitamin E. The best sources of vitamin E are found in nuts and seeds like almonds and sunflower seeds
Wheat germ oil contains the highest amounts of Vitamin E with over 100% RDA per tablespoon.
Most vegetables and fruits are not high in Vitamin E and many servings are required to get a substantial daily amount.
Do not over consume any beneficial oil to prevent risk of bleeding and stroke and other potential negative side effects. One tsp. – one tbsp. per day is sufficient for any healthy oil used as treatment. Do not exceed RDA of any vitamin and always be sure to look for only bio active natural sources. Do not forget children and pets have different RDA levels for safe consumption.
The majority of synthetic vitamins are not bio equivalent!
Oleic Acid is still number one and the amount of oleic acid present may be the determining factor for efficacy in all healthy oils including fish oils.
Thousands of studies have confirmed the benefits of healthy oils like olive oil, cod liver oil and other fish oils like salmon oil. While studies may seem contradictory, current research is focused on improving our understanding on the combined effects of fats and other foods including saturated fats, plant based omega 3’s, soy, trans fats and various other fat and food based combinations like fructose. They may help to shed light on seemingly previous dietary research contradictions and recommendations.
This is a minor overview of some of the factors addressed through current findings based on food and fat combinations. Many factors influence study outcomes and a moderate approach remains the best approach when attempting to influence health outcomes.
