We've all been there before. You're living a stressful life and not eating as well as you could be. Perhaps you're feeling generally run down and could use a boost. So, you might thing taking a multivitamin would be a good idea, just to cover your bases.
But taking a multivitamin may not be the answer.
Recently I had some bloodwork done. One thing they checked were my hemoglobin (iron) levels. They came back showing that my blood was really rich in hemoglobin (iron.) To the point that it was slightly above normal. Had I been taking a multivitamin with iron, I could have pushed my iron levels to an unhealthy level and became seriously ill.
They also took my vitamin D levels, which were on the low side of normal. To really get the benefit of D and raise my levels, my doctor wanted me to take 5000 IUs of vitamin D daily. In a multivitamin you'll get maybe 400 IUs--not enough to raise your levels or really see any benefit from it. Most of us are D deficient and can benefit from at least 5000 IUs a day. Some people may not need that much. Others may need way more. Without testing, it's a shot in the dark when it comes to a dose, so it's always best to find out first what's going on with your levels before supplementing. (You can get tested at your doctor's office or try a test kit like this.)
Well, what about just eating whole, nutritious foods?
Eating whole, fresh, nutrient-dense foods is always a great idea and what we should all strive to do. But even with eating the best foods, there may be things that your body still needs. Especially when it comes to B vitamins. B12 is especially difficult to get from your diet because it's only present in a handful of foods (salmon, calf liver, grass fed beef, lamb, eggs). The cards are stacked against me when it comes to B12 because not only do I not eat much of the food sources, I found out through my blood testing that I actually have a gene mutation that makes it difficult for my body to absorb and utilize B vitamins. (Called a MTHFR mutation) So, I have to take care to supplement with the active forms of B12 (methylcobalamin), and folic acid (l-methyl folate) (and niacin to help absorb their by-products once the body has broken them down.). Sometimes diet and even the whole food supplements just aren't enough and you need to get pure standardized forms of these vitamins.
When it comes to supplementation, it's all very individual. It's about what your body actually needs. When you take a multi, no matter how "clean" it may be, you're putting yourself at risk for either getting too much of something or not enough of what you need. If you're experiencing sluggishness, brain fog, and general malaise, you may be deficient in one or more vitamins or nutrients and getting a blood test can help you figure out the missing pieces of your nutrition puzzle. There may be instances where taking a multivitamin is a good idea, but it's really dependent on what your body needs.
