Synergy with Existing Protocols
Testing water-soluble vitamins4like B vitamins, vitamin C, and
biotin4can help uncover hidden deficiencies that may be
causing low energy, mood changes, poor immunity, or other
health issues.
Because the body doesn’t store these vitamins well, they can be
easily depleted by stress, illness, digestive problems, or certain
medications.

supplements and diet changes are truly helping. It makes care
more targeted and effective.
