The quick read

  • The bottle and box are labeled 100 mcg (4000 IU), 2 fl oz, 60 servings, bone support, and immune support, pineapple flavor. Heivy vitamin D3 drops pack shot
  • NIH ODS says vitamin D helps the body absorb calcium, and that the immune system needs vitamin D. The recommended amount for adults 19 to 70 is 15 mcg (600 IU) a day. NIH ODS vitamin D fact sheet
  • The same ODS sheet sets the daily upper limit for adults 19 and older at 100 mcg (4000 IU) from food, drinks, and supplements combined. One serving of these drops is that whole upper limit. NIH ODS vitamin D fact sheet
  • ODS says both D2 and D3 raise vitamin D in the blood, and that D3 might raise it higher and for longer than D2. The sheet was updated November 8, 2022. NIH ODS vitamin D fact sheet

One serving is the adult upper limit

Buy the single bottle if you want 60 servings of pineapple D3. Buy the two-pack if you want two of those bottles. Both are the formula labeled 100 mcg (4000 IU) for bone support and immune support. Heivy vitamin D3 drops pack shot

That 100 mcg serving is not the 15 mcg (600 IU) amount ODS lists for adults 19 to 70. It is the 100 mcg (4000 IU) upper limit ODS lists for adults 19 and older, counting food and supplements together. NIH ODS vitamin D fact sheet

What the dropper is for

ODS describes vitamin D as the nutrient that helps the body absorb calcium, one of the main building blocks for bones, and says muscles, nerves, and the immune system need it too. NIH ODS vitamin D fact sheet

Heivy's page says to take 20 drops (1 ml) daily with a meal and to shake the bottle. The Supplement Facts panel is where that amount per serving has to be readable. Heivy liquid vitamin D3 drops product page FDA dietary supplement labeling guide

What to check on the label

Micrograms and IU

Confirm the serving says 100 mcg and 4000 IU, and that you are counting other vitamin D you already take. NIH ODS vitamin D fact sheet

Servings in the bottle

The page lists 60 servings in 2 fl oz, at 20 drops per serving. Heivy liquid vitamin D3 drops product page

Single or two-pack
