The two fields you mentioned aren’t really for Vitamin D production.
The Sun Gazing field is to replicate the effects of sun gazing, which is a type of spiritual practice. People who practice it have a list of benefits, but vitamin D production isn’t on that list (or not high on that list). That being said, if your body is going to make vitamin D as a result of your sun gazing (be it, energetic or the physical practice of sun gazing) your body is going to make its normal form of vitamin D (what you’re calling sulfated).
Sun Free Sun Tanning causes the body to produce melanin, which is the pigment responsible for giving us that tanned color. That isn’t vitamin D.
There is Vitamin D Production (Energetically programmed audio) which stimulates our body to make more vitamin D. Since it’s our body which is making the vitamin D, here too, it’s going to make it’s usual form of vitamin D.
