Vitamin D daily requirements calculation

 To check the Daily Required Value (%DV) on a Nutrition Facts label, look at the % Daily Value column on the right side of the label.



What % Daily Value Means



  • The %DV tells you how much of a nutrient one serving of the food gives you compared to the total amount you need in one day.
  • The percentages are based on a 2,000 calorie per day diet.


This means one serving gives you 4% of the total sodium you should eat in one day.


If you eat 2 servings, you would get:

4% × 2 = 8% DV





General Rule



  • 5% DV or less = low
  • 20% DV or more = high



So if a food has:


  • 15% calcium → moderate source
  • 25% vitamin D → high source






Quick Example



If the label shows:


  • Vitamin C = 10% DV



You would need 10 servings to reach 100% DV:

10% × 10 = 100% DV





In Simple Words



  1. Look at the %DV on the right.
  2. This shows how much of that nutrient you get per serving.
  3. Add the percentages if you eat more than one serving.
  4. Aim for higher %DV in good nutrients (fiber, vitamins).
  5. Aim for lower %DV in nutrients like sodium and sugar.



๐Ÿ’ก % Daily Value Cheat Sheet (Easy to Remember)




1. Look at the %DV column



This tells you how much of your daily need for each nutrient is in one serving.





2. Use the 5–20 Rule

% Daily Value

Meaning

5% DV or less

LOW (not much of that nutrient)

20% DV or more

HIGH (a lot of that nutrient)


3. What Should Be LOW



Try to keep these nutrients LOW:


  • Saturated Fat
  • Trans Fat
  • Sodium
  • Added Sugars



Look for 5% DV or less for these.





4. What Should Be HIGH



Try to get MORE of these nutrients:


  • Fiber
  • Vitamins (A, B, C, D, E, K)
  • Calcium
  • Iron



Look for 20% DV or more for these.





5. If Eating More Than One Serving



Multiply the %DV:


Example:

Label says 10% Iron per serving

If you eat 2 servings:

10% × 2 = 20% DV of Iron





6. Goal for the Whole Day



Try to get 100% DV total across all meals.





Quick Example Using Your Label

Nutrient

%DV

Vitamin B12

15%

If you eat 2 servings:

15% × 2 = 30% DV Vitamin B12





✅ 

One Sentence to Memorize



5% is low, 20% is high — keep bad nutrients low and good nutrients high.



How to Read It



Example from your label:

Nutrient

Amount in one serving

% Daily Value

Sodium

85 mg
