The essentials

A closer look.

EuroMedica's Quercetin Plus Vitamin C combines quercetin, a flavonoid found naturally in plant foods, with vitamin C to support immune function and healthy inflammatory response. This pairing is deliberate: vitamin C may help regenerate quercetin in the body, potentially extending its activity at the cellular level. Formulated for adults seeking antioxidant support during seasonal challenges or periods of immune stress.

Why It's Worth Considering: EuroMedica is known for sourcing well-characterized ingredients and pairing compounds with complementary mechanisms, making this combination a practical choice over single-ingredient options.

More category questions

How much vitamin C should I take daily?

For maintenance, 500-1000mg daily is sufficient. For immune support during illness, 2000-4000mg in divided doses. The body can only absorb ~200-500mg at once, so split large doses throughout the day. Liposomal forms bypass this limit with 2-3x better absorption.

Is liposomal vitamin C worth the extra cost?

For most people, standard ascorbic acid at 500-1000mg is sufficient. Liposomal vitamin C is worth the premium if you need higher therapeutic doses (2000mg+) without GI distress, or if you have absorption issues. Studies show liposomal C achieves 2-3x higher blood levels than standard forms.

Can I take too much vitamin C?

Vitamin C is water-soluble and excess is excreted in urine. The main risk of high doses (3000mg+) is GI distress (diarrhea, cramping) and increased oxalate production, which may contribute to kidney stones in susceptible individuals. The 'bowel tolerance' test — increasing dose until loose stools, then backing off — is a common practitioner approach.

Does vitamin C really help prevent colds?

Meta-analyses show regular vitamin C supplementation reduces cold duration by 8% in adults and 14% in children, and reduces severity. It does NOT prevent colds in most people, but it does in those under physical stress (athletes, military). Taking vitamin C after cold symptoms start has minimal benefit — daily prevention is key.

When is the best time to take vitamin C?

Take with food to reduce potential stomach acidity. Morning dosing is common since vitamin C may mildly increase alertness. If taking large doses (1000mg+), split into 2-3 doses throughout the day for better absorption and sustained blood levels.
