You can start consuming placenta products even as young age. But the effect may not seem to react as effective as elderly consuming.

For Children. i think it’s not too advisable because children are always active and at their growing age even if they consume the effect won’t be much from them.

For adult to elderly. This will show more effect as most the growing age is over. With placenta consumed. It may help boost up their immune system and helps brings back the youth in them.
