Because most Vit D, D-3 is oil soluble, it may not benefit from or need to be Liposomal.
Liposomal Vitamin C is 10,000% more effective that regular Vit C, because regular Vit C is 90% denatured (destroyed) by stomach acid and the remaining 10% is only about 5% absorbed into the blood stream.
Liposomal Vit C solves both problems, it is somewhat like Linus Pauling's IV Vitamin C, that Linus Pauling claimed cured his cancer for decades.
Drug companies used Oral Vit C to claim it did not work for cancer, but now decades later NIH studies and some Covid19 emergencies trials used IV Vitamin C, Vit B-1 Thiamine and a steroid to turn around deadly sepsis and save peoples lives, some that were about to be put on ventilators with Covid19 Back in April. 5 days after that IV treatment all but one patient that was about to be ventilated walked out out of the Hospital. Only one ended up on the ventilator
