Arggghhhhhh! Vitamin D %

Where can I find the grams, or IU, or UG or any precise measurement for Vitamin d? I'm running a little short and need to up my intake. 30% of RDA is not useful when the RDA is age-dependent. Help!!!!! (I've searched the oracle, but want to look at specific items in the grocery store and their labels list percentages).

  • Hi there!

    Products show % Daily Values on the nutrition labels. The %DVs are are standardized so that you can compare different products more easily.

    The %DV for vitamin D is equal to 20 micrograms on the newer style of labels (American 2016 label type in Cronometer), or 400 IU on the older label style.
    1 International Unit (IU) = 0.025 Microgram (µg or mcg)

    I hope that will help you when you are looking at labels at the grocery store.

    Best,

  • Unfortunately, it's next to impossible to get 100% of your vitamin D from food. The sun and supplements are the best sources.

  • does Chronometer have a way to track/input sun exposure for vitamin D?

  • We don't have a default way to add vitamin D produced from sun exposure. If you have an estimate of how much vitamin D you have made (there are some good calculators our there where you can input your latitude, skin colour, how much skin is exposed, etc.)

    You could create a custom food for vitamin D to add a value to your diary.

  • thanks @Karen_Cronometer ! Do you have any suggested calculators?
    I got what seems to be a remarkably brief recommendation: every other day for 4 minutes (https://fastrt.nilu.no/VitD-ez_quartMED.html)

  • Thank you for the tip! I was looking for it.

  • Hello. I have looked up the link and it says I need 87- Jm-2. I have no idea what that means. Anybody able to tell me or recommend a site with more understandable results? Thanks..

  • @mentalrain

    I'm not in Europe but just submitted using hypothetical answers and found results at the bottom of the page that told me minutes that I would need to spend in the sun on a specific day (as well as minutes it would take to have a sunburn).

    If these results aren't visible, I recommend contacting the web company.

    Kind regards,

    Hi there, how can I remove vitamin D from the nutrition scores? Since sun exposure cannot be appropriately tracked I would like to have a way to remove the bias from the low food-derived vitamin D values. Thanks!

  • Hi Nutritarian,

    You are not able to customize the nutrients included in each score. I'll pass along your feedback about that!

    You could consider removing the Nutrition Scores that contain Vitamin D so that you can focus on the scores that are more interesting to you. You can select which scores you would like to see in your diary page from the Settings tab, under Display.

  • Thank you Karen!

  • This may be slightly off the original topic but is at least tangentially related to the question.
    I recently noticed that Greek Yogurt, Plain, Lowfat; Food #458233, NCCDB; was listed in NCCDB as 3.23 IU, 0.8% DV per cup. However, the same database lists 2% milk, Food # 455714 with 119.56 IU, or 29.9%.
    Grocery store milk is fortified with Vitamin D and I assume the low-fat yogurt numbers are based on milk that is not. But the yogurt that I eat quite a bit of is homemade with store-bought low-fat milk. Creating a custom entry for yogurt that supplies 25% of DV goes a long way toward solving my problem.
