Vitamin C is a potent antioxidant that helps protect cells from oxidative stress caused by things like intense exercise, pollution and UV exposure.

Your body needs vitamin C to make collagen. That makes it important for skin, joints and connective tissue. Pair it with skin-focused services like red light therapy or the T-Shape 2 Facial.
4. Levels You Can't Reach With Pills
This is the key advantage. Your body tightly limits how much vitamin C you absorb by mouth. IV delivery bypasses that limit. Read IV Vitamin C vs. Oral Vitamin C.
