What does vit A even do

lobotomize-me

Ray encourages vit A supplementation through weekly liver. But i havnt yet understood what it does can someone help me out with this

Vitamin A and T3 are required to turn cholesterol into steroid hormones
It is also anti-estrogenic and an aromatase inhibitor
It also has some anti-cortisol effects
It's an important nutrient for skin health, especially for acne or psoriasis

I'm not sure he ever advised for weekly liver without context. It depends among other factors on how much sunlight you get and how good your metabolism is.

Vitamin A exists mainly in two forms, to simplify: vitamin A = retinol. Provitamin A = carotene. Provitamin A (carotene) has its own function (for example, to protect membranes as an antioxidant), but it can also be converted into vitamin A (retinol). The conversion rate is quite low and decreases with age and context. We then speak in equivalent units.
NB: 10,000 IU = 3,000 mcg Vit A. We divide the IU by 0.3

Let's simplify once more. We're only concerned with vitamin A (retinol). We mostly distinguish a role in vision, and a role in cell differentiation and growth. Not only.
We talk about vitamin A1/X and the latest version is vitamin A5/X.
"Vitamin A" or "retinol" are two fairly equivalent, interchangeable terms, although purists may have some nuances to add: Retinol refers to the entire molecule.

As DavidPS said:

Vitamin A5 helps activate something called the Retinoid X Receptor (RXR), which is like a central control panel or "master switch" for many important functions in the body.

How does it happen (pathway)?
Retinoic acid binds to the receptors RAR (retinoic acid receptor) and RXR (retinoid X receptor) before being activated into the active hormone. Note that vitamin D and vitamin A partly use the same transport pathway, particularly in their action on genes. They both act by binding to nuclear receptors that control gene expression, and these receptors require a common partner, the RXR (retinoid X receptor), to activate gene expression. It is also important to avoid taking a high dose of vitamin A without supplementing with vitamins K2 and D3.
Best at maximum 5 000 UI or 1 500 mcg Vitamin A (and not without D3) to avoid interference with osteocalcin, a protein involved in bone formation. Take once a week. Not at the same meal (with fat).
