Each chewable tablet gives you 500mg of **Vitamin C**, landing in the lower end of the clinical range (250–2,000mg). At the suggested two tablets daily, you'd hit 1,000mg — a well-studied dose for immune support and antioxidant protection. The formula blends ascorbic acid with calcium ascorbate and sodium ascorbate, which partially buffers the acidity and makes it gentler on your stomach than pure ascorbic acid.
You'll also find small amounts of **Acerola extract** (10mg) and **Rose Hips** (4mg), but these are far too low to contribute meaningfully — rose hips research uses 2,500–5,000mg. They're essentially trace additions.
The chewable format does come with a gram of sugar per tablet. That's negligible for most people, but if you're taking two daily and prefer to avoid added sugars entirely, a capsule format would suit you better.

Other Ingredients (11)
CarrageenanThickener
Can break down into poligeenan (a known inflammatory) under stomach acid conditions. Tobacman (2001, Environmental Health Perspectives) reviewed evidence linking carrageenan to intestinal inflammation and ulceration. Major food brands (Silk, Stonyfield) have voluntarily removed it. Used only as a thickener — provides no health benefit.
FructoseSweetener
Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.
SucroseSweetener
Added sugars and high glycemic load; dental caries risk
XylitolSweetener
A FODMAP sugar alcohol that can cause GI distress (bloating, gas, diarrhea) at moderate doses (>10-20g/day), though supplement amounts are typically small. Extremely toxic to dogs — households with pets should store securely.
AnnattoColorant
Natural yellow-orange colorant derived from the seeds of the achiote tree (Bixa orellana)
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
