Frequently Asked Questions

What does Vitamin C do for the immune system?

Vitamin C supports multiple layers of immune defence: it stimulates the production and function of neutrophils (the most abundant white blood cells), enhances lymphocyte (B and T cell) differentiation and proliferation, supports Natural Killer cell activity, and is a potent antioxidant that protects immune cells from oxidative damage during immune responses. Deficiency significantly impairs immune function; supplementation helps maintain optimal immune defences, particularly during periods of high physiological stress.

Why is Rose Hips included with Vitamin C?

Rose hips (Rosa canina) are a concentrated natural source of vitamin C and contain bioflavonoids — plant compounds that act synergistically with ascorbic acid. Bioflavonoids may enhance vitamin C's uptake into cells, prolong its antioxidant activity, and provide their own anti-inflammatory and antioxidant benefits. The combination was traditionally used before synthetic ascorbic acid was isolated — the natural whole-food context was recognised as more effective than the isolated vitamin alone.

Can 1500mg of Vitamin C cause any side effects?

Vitamin C is water-soluble — excess is excreted in urine rather than stored. At 1500mg daily, mild digestive discomfort (loose stools, stomach cramps) may occur in sensitive individuals. To minimise this, split the dose into two portions with food. The tolerable upper intake level is 2000mg/day. People with kidney disease or a history of kidney stones (particularly oxalate stones) should consult their GP before taking high-dose vitamin C.

When is the best time to take Vitamin C?

Vitamin C can be taken any time of day with food. Splitting the 1500mg dose — 750mg morning, 750mg evening — maintains more consistent plasma levels than a single large dose (as excess is rapidly excreted). Take with food to reduce the risk of stomach discomfort from the acidic ascorbic acid.

Can Vitamin C help with iron absorption?

Yes — this is one of vitamin C's most practically important roles. Vitamin C significantly enhances the absorption of non-haem iron (the type in plant foods, fortified foods, and iron supplements) by reducing ferric iron (Fe3+) to the better-absorbed ferrous form (Fe2+) and preventing its oxidation in the gut. Taking vitamin C alongside iron-rich plant foods or iron supplements can increase iron absorption by 2–3 times.
