The European Food Safety Authority (EFSA) confirms that vitamin C contributes to the normal function of the immune and nervous system, reduces tiredness and fatigue, contributes to collagen formation (for bones, cartilage, skin, gums and teeth), protects cells from harmful stress in the body, and improves iron absorption (EFSA NDA Panel, 2009). These benefits already apply at a considerably lower, typical daily intake – such a high dose (1000 mg) mainly ensures reliable coverage even on days with a poorer diet.
For the general population, probably not significantly. An extensive review of 29 studies (over 11,000 people in total) found no evidence that regular vitamin C intake reduces the incidence of colds in the general population. However, in people exposed to extreme physical exertion (marathon runners, skiers, soldiers), regular intake almost halved the frequency of colds. In adults who already have a cold, regular intake shortens the duration of symptoms on average by only about 8% (Hemilä and Chalker, 2013) – so it's a mild, not a miraculous, benefit.
No, it's within the safe limit. The US Institute of Medicine has set the upper safe limit of daily vitamin C intake for adults at 2000 mg per day; no consistent serious adverse effects have been observed at typical high doses (NIH ODS, 2021). This product's dose (1000 mg) is thus safely below that limit, although in more sensitive individuals such a high single dose can cause mild digestive issues, such as diarrhea.
Yes, that's actually one of its well-proven benefits. Vitamin C helps the body better absorb iron from plant-based food (e.g. legumes and grains), while also reducing the inhibitory effect of certain plant compounds on absorption. This effect is well researched and recognized by EFSA, so the product can be a useful addition to a meal rich in plant-based iron (NIH ODS, 2021). But don't forget – for this to actually help, you still need to consume enough suitable food.

The product is not intended for children, pregnant women or breastfeeding mothers.
People with hemochromatosis (an iron metabolism disorder) should consult a doctor before use, as vitamin C increases iron absorption.
