Frequently Asked Questions

What is PureWay-C and how is it different from ascorbic acid?

PureWay-C® is a patented form of vitamin C that combines ascorbic acid with lipid metabolites — fatty acids and bioflavonoids. This complex significantly improves the uptake of vitamin C into cells (particularly immune cells like lymphocytes and neutrophils) and extends the time vitamin C remains at high concentrations in these cells. Clinical studies show PureWay-C achieves higher plasma levels faster and maintains them longer than standard ascorbic acid.

Why does cellular retention of vitamin C matter?

Immune cells use vitamin C intensively during infection and oxidative stress — they concentrate it to levels 80x higher than plasma. The longer vitamin C is retained in these cells, the more effectively they can produce reactive oxygen species to kill pathogens, synthesise antibodies, and perform other immune functions. PureWay-C's longer cellular retention directly supports immune cell function more effectively than standard vitamin C.

What dose of vitamin C does each tablet provide?

Check the current product label for the specific vitamin C content per tablet. PureWay-C products typically provide 500mg–1000mg ascorbic acid equivalent per tablet. Standard supplementation is 500–1000mg daily; therapeutic doses during illness may be higher — consult a healthcare provider.

Is PureWay-C suitable for people with sensitive stomachs?

PureWay-C contains lipid metabolites that buffer the acidity of vitamin C, making it gentler on the stomach than pure ascorbic acid. People who experience stomach discomfort with regular vitamin C supplements often tolerate PureWay-C better.

Can I take Doctor's Best Vitamin C PureWay-C alongside zinc for immune support?

Yes. Vitamin C and zinc are synergistic for immune function — vitamin C supports lymphocyte activity while zinc supports thymulin production and T-cell function. They can be safely combined at standard supplemental doses.
