It is essential for older adults to consult healthcare professionals before starting vitamin C supplements to tailor the dosage to their health status.

Vitamin C Side Effects in Pregnant Women

Pregnant women need adequate vitamin C for fetal development, but excessive intake can lead to side effects like gastrointestinal distress and increased risk of kidney stones.
