What a difference, eh?
I later learned that the RDA is substantially less than the dosages naturopaths recommend which is usually in the realm of 2,000-8,000 IU. Although this vitamin can be toxic in very huge amounts, the average Joe Schmoe is deficient in Vitamin D and will benefit from regular, high doses. Pediatricians also recommend that exclusively breastfed babies get 400 IU via drops - something I scoffed at when Ro & Zo were babies. I don't need to supplement, I have a good diet and I am giving my children the best nutrition possible! I was oh-so-wrong and am to this day eating very large slices of humble pie. See, that attitude is fine when the bf mama's blood D levels are optimal (min ~ 40 ng/mL) but in my case, I was deficient and so was definitely not passing enough of this crucial vitamin to my babies. You can fix this by exposing your baby to 20 minutes of sunlight daily - try to expose as much skin as possible to absorb optimal amounts of the vitamin. However, if you live in an area where this is not feasible, you need to make sure your levels are high enough and if not, start taking Vitamin D3 supplements yourself (I do adhere to the 6 month rule of exclusive breastfeeding so recommend supplementing baby directly after this mark). If you are not breastfeeding or want to supplement directly, you can give your baby Carlson Vitamin D3 drops which will serve the purpose nicely. Point is don't assume your Vitamin D levels are optimal!
I honestly believe that it was my Vitamin D deficiency that contributed to Z's teeth being in the condition they are today. Mommy guilt aside, both my kids have the same diet, were breastfed for the same amount of time and have the same oral hygiene. So, what gives? With Ro, I took a regular prenatal and ate a balanced diet which I suspect raised my levels somewhat. With Z, the sickness was so bad I could not take any supplements, I was nursing Ro through my pregnancy and my father passed away soon after she was born, not the most optimal foundation for good immunity is it? If you're reading this when you grow up Z darling, please do not take this in any way as an indication that you were not loved or cared for as much as R - it was purely circumstantial and was never intentional and I love you so very much!
I digress..as usual might I add :-)
Vitamin D is not only essential for good bone health (including teeth) but a great immunity booster. I have read accounts of people mega dosing with Vitamin D when sick and finding that they recovered from colds faster. Research studies also show that certain types of cancer can be prevented by taking adequate amounts, same goes for ailments such as diabetes & depression. For women, this vitamin is essential for hormonal health - it plays a significant role in reproduction and fertility and has been reported to help with PMS as well.
The best way to supplement is really to get out in the sun, as I said earlier. Even if you don't live in a climate that's sunny most of the year around (ah if only I could live in San Francisco), try to maximize your exposure in the months that it is sunny outside because your body does store Vitamin D and those levels can get you through the winter months. Remember to try and get at least 20 minutes of bare skin exposure and at a time when the sun is at its peak. If you do want to supplement, always buy Vitamin D3 as that is the most natural form. Vitamin D2 is synthetic and although widely available, can even cause problems with the functioning of Vitamin D3. Another way of getting adequate amounts of Vitamin D is by supplementing with Cod Liver Oil. See post on cavities for more info.
