Liposomal Vitamin C. I’ve read it’s supposed to be as good, or better than IV.
Oral could be tricky if someone’s barfing, though =/
Liposomal Vitamin C.
Good stuff. Much higher absorption rate than regular oral vitamin c.
Easy to make at home using water, lecithin, and some form of quality vitamin c.
You will also need a small ultrasonic cleaning unit.
I made a batch just this afternoon using acerola cherry powder.
