When i first took vitamin A. It quickly made me super dry then i i experimented around with other vitamins and i eventually got my skin to be super glowy. Dewy as they called it. I was like kinda sticky but my dandruff was completely gone for weeks and then after a bit the effect completely went away. And now nothing i seem to do is helping me get back to that effectHe doesn't prove we don't need it. He sets out with an idea in mind and selectively takes compelling information to back up his point - it isn't a balanced arguement.
Help me understand how we metabolise copper without ceruloplasmin and why retinol binding protein is specifically made by the body and its relationship to zinc. Explain how we properly metabolise calcium and phosphorous in the absence of vitamin A?
Explain how a book condemning vitamin A as a poison can completely miss the necessity of cofactors k2 and vit D - the fundamental point that undermines his work.
Vitamin A, K and D must be in balance. Vitamins A and D in balance are key to a healthy mucosal barrier and immune system. Vitamin K2 is needed to properly utilise A and D.
They all work together to metabolise, shepherd and balance the minerals we take in.
A far more balanced conclusion would be that vitamin A is easy to imbalance due to a number of factors, perhaps with a modern diet lacking in k2 alongside (this is just an idea for the sake of example) modern dairy feed perhaps skewing the balance in favour of A over k2.
Also, far more likely, the widespread absence of sunlight on skin in people's lives in the modern day - this is absolutely going to create an imbalance between vit D and vit A which may in turn cause chronic issues down the line. Usage of sunscreen and overuse of soaps adds to this problem.
I'm not saying don't temporarily avoid vitamin A to see how you get on, I'm saying the conclusion that it's a poison is a dangerous and unhealthy position to take.
That's the problem - the guy that writes a balanced research book won't get wide exposure. Dogmatism and fear create a spectacle and can gain traction which can provide a sense of esteem or credibility to a writer merely by having their ideas talked about, no matter how imbalanced their perspective might be.
Do what feels right to you, but also be aware that vit D, K2 and a little magnesium might bring about a far healthier non restrictive non orthorexic balance.
I'm not averse to the idea we don't need huge amounts of vitamin A, but we certainly need some.
