October 2013 - If the picture to the left looks familiar, daunting and confusing, realize that you are not alone. You may have heard from various sources, "take this supplement for joint pain", "take this supplement to boost metabolism", "this one will help you sleep at night", "take this one and live forever!". Since the FDA does not regulate supplements there are many confusing stories as to who should take what and why. This article is meant to help you make some sense of vitamin supplements as well as herbal supplements. We will cover those most often taken from off the shelf such as multivitamins, vitamin C and calcium as well as herbal supplements that are meant to boost brain function, help you sleep and decrease joint pain.
I'd like to start with Multivitamins. Who should be taking them? Everyone! Even if you eat your daily servings of fruits and vegetables (9-11) you are not getting enough nutrients from food. Our soil is depleted from over-farming and this decreases the nutrient density of our fruits and vegetables anywhere from 10-25%. When shopping for a multivitamin look for 100% daily value of the 12 essential vitamins and minerals. Do not purchase anything with 366% of any vitamin or mineral, you can over dose. Try to buy compressed tablets as opposed to capsules. Gelatin capsules do not release evenly and you can break tablets in half to spread out your vitamin and mineral intake by taking half in the morning and half in the afternoon. Multivitamins should be taken with food because the body can not process most vitamins without fat from food.
Calcium: Who should be taking it? Probably nobody. It is often believed that we need calcium for strong bones because our bones are made of calcium. This partly true fact has been perpetuated by the dairy industry to sell more milk. Why is this partly true? Our bones and teeth "contain" 99% of the calcium in our bodies but our bones are made up of only 10% calcium. The other 90% is made of collagen, a protein made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. Calcium supplements have also been shown to increase the risk of heart attacks in post-menopausal women. The truth is, due to crafty advertising, the average American drinks enough milk and eats enough dairy to fulfill the body's requirements twice over. What about those that do not consume dairy? There are over 20 non-dairy food sources of calcium including: kale, collard greens, blackstrap molasses, broccoli and oranges.
Vitamin C: Everybody needs vitamin C but should you be getting it from an extra pill? Let's just C. (I made a joke.) Vitamin C is important for the growth and repair of all major tissues in your body. It is also an antioxidant, important for blocking the damage of free radicals that can lead to cancerous cells. It is rare to be deficient in Vitamin C, very rare. However smoking lowers the level of vitamin C in the body. So smokers should be taking Vitamin C, well smokers should stop smoking but that's an article for another time. If you are already taking a multivitamin you shouldn't need to take an extra pill. Here's a tip: if your urine is bright yellow and looks like it could glow in the dark, you have too much vitamin C in your system. There is no conclusive evidence that taking vitamin C supplements will help or prevent any disease or illness.
Vitamin D: Here's one that I will agree most of us need, with one caveat. Vitamin D is important to support bone strength, reduce high blood pressure and cholesterol, control diabetes and weight, fight autoimmune diseases and skin conditions. 80-90% of the vitamin D we need we get from exposure to sunlight. A supplement is not needed for most of the year. It is however strongly suggested to take a supplement from November-April if you live north of the 38th parallel or Atlanta, Georgia. The reason is most people do not spend as much time outside to get enough exposure to the sun during these months. You can however avoid taking a supplement if you find a way to be outside for fifteen straight minutes in the cold. This should keep your body producing vitamin D for two days.
Great overview and set of recommendations. I would, however, suggest that everyone - at least in the Western world - needs omega-3 fatty acid supplementation. We don't typically eat enough omega-3s, which act to reduce inflammation; and we eat an abundance of omega-6s, which act to increase inflammation. Note that inflammation is not categorically "bad;" it's a natural and necessary response to infection. Too much inflammation is the problem. At any rate, extra omega-3s will help maintain a balance between the two opposing forces.
ReplyDeleteYeah I think i missed a great opportunity with omega-3's. New research suggests it is not as beneficial for brain function as previously thought. However it is still needed for joint function and heart health. Vegetarians/Vegans are always looking for an alternative to fish oil and I always suggest a DHA from algae along with avocados and flax seed. Though now with the radiation spill I am not sure anything from the Pacific is safe anymore.
