Fat-soluble form of vitamin C used as preservative
Purified WaterSolvent
Water meeting USP specifications used as solvent/vehicle in gummies and liquids
HypromelloseCapsule
Plant-derived capsule material from cellulose
Microcrystalline CelluloseBinder

How to Take It
Best taken in the morning
Many people prefer it earlier in the day; there's no evidence timing changes anything. Absorption is fine with or without food.
With or without food
On the label
Dissolve 1 lozenge under the tongue first thing in the morning, or as directed by a qualified health care practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.

Sources & Scoring
Nutrient data (RDA, UL, and safety thresholds) sourced from the NIH Office of Dietary Supplements and the National Academies Dietary Reference Intakes (DRI).
This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.
The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
