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.
