Other Ingredients (6)

MaltodextrinBinder

Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Carnauba WaxCoating

Hard plant wax from the carnauba palm used to glaze gummies and tablets

Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements

Croscarmellose SodiumDisintegrant

Cross-linked cellulose derivative used as a superdisintegrant

Stearic AcidLubricant

Saturated fatty acid used as tablet lubricant

How to Take It

Take it anytime

Plain ascorbic acid is acidic — high doses can bite on an empty stomach. Take it with food if that happens, and split doses above ~500 mg.

With or without food

On the label

Take one (1) tablet daily with any meal for maximum daily results, or as directed by your healthcare provider. Do not exceed recommended dosage.

General guidance based on the ingredients, not a substitute for the label or your doctor.
