Vitamin D is well-known for helping the body fight illnesses ranging from the common cold to cancer. It can modulate the innate and adaptive immune responses and decrease the risk of autoimmunity. To know how much you should take, get your levels tested next time your doctor does bloodwork. Many lab ranges say that above 30 ng/mL falls within the “normal” range but I highly recommend blood levels of 80-100 ng/mL as ideal for optimal health, based on the vitamin D research of many doctors I follow who have been studying the immune system.
The best way to get vitamin D may be through UV rays of the sun, but that only works if you are out in it, ideally with your torso exposed to its rays. Needless to say, we in Vermont don’t see much of the sun during our long winters and many of us spend most of our time indoors even in the warmer months. So, supplementation is crucial.
5000-10,000 IUs is the recommended dose for vitamin D when trying to increase blood levels. Some people need to take even more to get their levels to where they want it, so testing is vital because we are aiming for 60-90 ng/mL and we don’t want the levels to be too high – over 100 or 120 ng/mL.
I carry several forms of supplemental vitamin D – capsules, gummies or liquid. We want to use D3, which can come by itself or along with A and K in ADK. I like to have both D3 and ADK on hand because I am trying to get at least 10,000 IUs in per day but we don’t need extra A and K, so I take 5000 IUs in the ADK blend and then take another 5000 IUs of just D3.
As for testing of vitamin D, when I had my levels tested in the spring, after taking 2-3000 IUs all winter, my levels were very low – 28 ng/mL. I increased my dose to 10,000 most days and by mid summer I was up to 53 – nearly doubled! I’m still working on it – I am aiming for at least 80 ng/mL. I like to keep a few different types of vitamin D on hand, just to mix it up. Currently I take the ADK in the morning, I put the liquid vitamin D in my smoothie or straight onto my tongue, and I have some caps at the office as well. I’m going to try the zero sugar gummies next.
I am putting together an immune bundle that includes vitamin D – additions or substitutions for different forms are available. I will be stocking ADK as well as the ones in the picture. My vitamin D collection will change or grow as I explore different brands as I’d like to stock dosages of 5000 and 10,000 IU (so you don’t have to take 5 caps of 1000 IU).
