So perhaps it’s A, and not K we need? And A in what form? Anyone trying this, and in what ratio?
I personally explored that by gradually increasing both over many years, while testing serum 25(OH)D3 and retinol as well as RBP (retinol binding protein) and aiming at the middle of the reverence range. Over time the ratio changed, so I assume it might actually be different for everyone too.
Is beta carotene a better approach, so it’s near impossible to over do it?
According to one study about 50% of females couldn't convert beta-carotene into proactive vitamin A very well. Since I already get plenty of it from a plant-based diet, I rather supplement the later.
Thereby found out that above 24.000 IU my infrequent psoriasis outbreaks ceased, and my craving for cod liver too (contains about 50.000 IU per can). After some time much less had the same effect. Wouldn't recommend this to anyone, unless tracking lab markers.
