Does the Vitamin K Shot Contain 100mcg of Aluminum?

The vitamin K shot is not a vaccine.

That doesn’t keep anti-vaccine folks from pushing misinformation about it and scaring parents away from protecting their babies from vitamin K deficiency bleeding.

Does the Vitamin K Shot Contain 100mcg of Aluminum?

Newborns have been routinely getting vitamin K shots since at least since 1961.

Babies do not get 100mcg of aluminum from a shot of vitamin K.
Babies do not get 100mcg of aluminum from a shot of vitamin K.

And except for a brief “vitamin K brouhaha” in the early 1990s, when a study suggested that vitamin K shots might be associated with childhood cancer (they aren’t), these shots have helped to nearly eradicate hemorrhagic disease of the newborn.

So why would someone want to skip it?

The photo above suggests that they think newborns get too much aluminum from the shot. If you look closely though, you can see why they are wrong.

The vial and package insert of vitamin K clearly states that it contains no more than 100 mcg/L of aluminum.

What’s a baby’s dose of vitamin K? They don’t get a liter! They get a single IM shot of 1mg of vitamin K, or 0.5ml.

So they are obviously not getting 100mcg of aluminum.

Do you see why?

With a concentration of 100 mcg/L or 100 mcg/1000ml (remember that one liter is equal to 1000 milliliters), since they are only getting a 0.5ml dose of vitamin K, they are getting, at most, only 0.05 mcg of aluminum.

That’s 0.00005 mg of aluminum, as compared to the 0.225mg of aluminum in the Hib vaccine.

Why is aluminum even added to vitamin K?

It’s not.

Keep in mind that aluminum isn’t even listed as an ingredient of vitamin K. But according to FDA rules, “Applicants and manufacturers must use validated assay methods to determine the aluminum content in parenteral drug products.” .

And like many other IV fluids, another ingredient of vitamin K, 5% dextrous hydrous (sugar water), does often contain some aluminum, about 17.3mcg/L. These small amounts of aluminum are present “because practically all materials used to manufacture containers for pharmaceuticals contain Al.” From aluminum oxide in glass components to aluminum used as catalysts to make plastics, it is hard to avoid aluminum. But as we have learned that premature babies could get total parenteral nutrition for prolonged periods of time and be exposed to too much aluminum, the FDA has taken steps to limit this exposure.

Vitamin K shots also don't contain mercury!
Vitamin K shots also don’t contain mercury!

Unfortunately, some of those steps, like the labeling of aluminum in vitamin K ampules is used to scare parents.

What to Know About Aluminum in the Vitamin K Shot

Neither the trace amounts of aluminum  or any other ingredient in your baby’s vitamin K shot shouldn’t keep you from protecting him from vitamin K deficiency bleeding.
