Do humans need provitamin A for optimum health?

I assume beta-carotine/provitamin A are not needed, if one gets their vitamin A through preform A/retinol(carnivore). Or possibly the preform is not needed, if one gets enough proform in their diet(vegetarian).

Vitamin A toxicity from consumption of Provitamin A sources?

Hey all,

Curious on daily consumption of high Vitamin A foods such as sweet potato, carrots, green leafy veggies, etc.

I found this source but it wasn't very clear to me what the upper limit on consumption of these food types is.

There was this statement:
> Many people in the United States take either isolated supplemental Vitamin A or other supplements that contain vitamin, A in addition to dietary intake. The current recommended dietary allowance of vitamin A is 800 retinol equivalents or 2700 international units (IU) for women[1].

It wasn't clear to me if this was applicable to Provitamin A sources.

The question is basically, can you consume sweet potato or any other very high Vitamin A whole food source (not supplement) daily without risk of Vitamin A toxicity?

Thanks for your input.

[Product Question] moisturizer with vitamin E and provitamin b5?

I’ve recently started using Byphasse lait demaquillant to take off my make up and although it doesn’t do the best job at that, it is incredibly moisturizing and feels amazing on my skin.

I was wondering if anyone knows how to find a product which contains both of those ingredients or has any recommendations that could work? Are there other names for vitamin E or b5? I’ve tried googling them together but the combination seems to turn up mostly products on amazon or NA stores which arent accessible to me (EU)

Do you need both preformed and provitamin A?

I understand your body can convert caretenoids into retinoids, but is it better to have it already formed, similar to how carbs are preferred for energy?

Dropped my best ever dad joke & no one was around to hear it

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies πŸ˜‚

These aren't dad jokes...

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
