Maureen,
We created our B12 recommendations chart *after* Taylor Wolfram noted that recommendation. When we published the chart, we didn’t believe there was convincing evidence for separate recommendations for older adults. But since we recommend over 50 mcg to meet EFSA standards for most adult options, I hope New Zealand will change its regulations.

Thanks for your reply. I read the response from Taylor Wolfram saying that you recommend 500 for older people, so I was hoping that you might be going to update your chart and then I could use it as a reference. Here’s the link to the answer:

Maureen,

Our chart of recommended intakes is under Essential Information on our main Vitamin B12 page. We don’t distinguish between adults of different ages. That’s unfortunate about New Zealand rules—good luck trying to increase the limits.

I live in New Zealand where stores are prohibited from selling B12 supplements in excess to 50mcg. I’m looking for information/facts that I can use to persuade the NZ Government to remove or increase the 50mcg limit. Any information you can send me would be appreciated.

Hi! Someone your age needs 1.8 micrograms of vitamin B12 every day. It’s best to start supplementing as soon as you go vegan. We recommend talking to your pediatrician. In the meantime, this is a helpful resource to read and share with your parents: https://vegetariannutrition.net/docs/School-Aged-Children-Vegetarian-Nutrition.pdf
