Vitamin C tablets can be beneficial for certain health conditions, but they are not a cure-all. Taking oral vitamin C supplements in combination with other vitamins and minerals seems to prevent age-related macular degeneration (AMD) from worsening. Some studies also suggest that people who have higher levels of vitamin C in their diets have a lower risk of developing cataracts. However, research shows that for most people, vitamin C supplements do not reduce the duration or severity of the common cold.
While vitamin C is essential for a healthy immune system, there's no evidence to suggest that supplements packed with huge doses of the nutrient will prevent you from getting sick. High-dose vitamin C may, at most, shorten a cold by one day.
It is important to note that vitamin C supplements are not a replacement for a healthy diet. You can get plenty of vitamin C from eating fruits and vegetables.
Here are some additional points to consider:
- Individual needs: The right amount of vitamin C for you depends on factors like age, sex, and overall health.
- Side effects: Taking too much vitamin C can cause side effects like stomach upset, nausea, diarrhea, and kidney stones.
- Interactions: Vitamin C supplements can interact with certain medications. It's important to talk to your doctor before taking any new supplements.
Always consult with your doctor or a registered dietitian to determine the appropriate dosage and suitability of vitamin C supplements for your individual needs.
