Hi Alycia,

Here's a link to a short video Dr. McDougall made regarding his recommendation for B12 supplementation: https://tinyurl.com/39jdvmmx . You'll have to go all the way to the end to hear his recommendation for dosage: 5 micrograms of B12 per day. However, you will be hard-pressed to find any B12 vitamins with that dosage; most tablets are either 500 micrograms or 1000 micrograms. Most of the doctors I've heard discussing B12 state that it is almost impossible to overdose on B12 and recommend taking one of the commonly-available tablets once or twice a week.

Here's a link to a video in which Dr. Michael Greger discusses his recommended dose for the average adult who is under 50 years of age: https://nutritionfacts.org/video/the-op ... or-adults/ . Dr. Greger takes into account how much B12 is typically absorbed; Dr. McDougall does not.
