Is that doctor selling medicine in a Facebook video real or fake?

Answered in a minute, with the warning signs and what to do right now.

Short answer

Very likely a deepfake

Many of these videos are deepfakes: scammers take real doctors' lectures or interviews and make that face say a new sales pitch. Vietnamese rules ban using doctors' names, images or medical facilities to advertise food products, so a supplement ad fronted by a doctor is wrong from the start.

My parents believe the ad. How do I talk to them without a fight?

Try three steps: ask instead of judging (where did you see this?); look it up together instead of for them; and give them a way out by saying the video is so convincing that doctors have had to issue denials.

We already bought it. Now what?

Don't stop prescribed medicine. Show the product to the treating doctor before using it. Supplements aren't medicine and can't replace treatment.
