I think we all know it in the back of our minds. Too much of a good thing can be bad. This scientifically holds true for consuming too many vitamins. There is so much well meaning information floating around the internet and our social circles, but much of it is not well researched, and therefore potentially harmful.
I doubt any of us are going to die from too much Vitamin C, but it sure can increase trips to the bathroom.
Most vitamins have a recommended UL or upper limit dosage. Beyond our recommended daily dose, we simply eliminate water soluble vitamins. However, vitamins that store in our fat cells can hang around and build up to cause unwanted side effects. Probably the most common effects are diarrhea, nausea or interaction with medications. The only reason to take more than the daily recommended dosage is because a healthcare provider recommends it. Otherwise, consider saving your money because vitamins and supplements are expensive!
As we age, or with certain other conditions, we may need more than a multi-vitamin, but from experience, I can tell you that I was taking more than I needed, and once I dialed back to a single multi and the recommended supplements from my doctors, my digestion improved. I’m not making emergency runs to the bathroom.
Ultimately, the best way to get our vitamins is through our food. Eat nutritious, wholesome and natural food. Fortified is not naturally filled with vitamins. It’s supplemented. Sometimes, that’s necessary, but avoid what you can. I know some health experts believe our food is less potent because of soil depletion and pollution, but still. A good wholefood multivitamin will do ya!
