Is it Safe to Take Vitamin C When You Are Sick?

Thanks for the question. While taking a single tablet of Vitamin C is generally safe and won't do any harm due to its water-soluble nature, I always advise people to obtain their Vitamin C from natural food sources like lemon juice for an average daily requirement. If you have any health concerns, consulting a doctor is recommended. For citrus fruits, oranges and sweet limes are high in Vitamin C.

Vitamin C Safety and Absorption

While Vitamin C is generally safe when taken in recommended doses, over-dosing can lead to side effects. Unlike other vitamins that can build up in the body, excess Vitamin C is completely excreted through urine by the kidneys. This misconception that 200 mg is the upper limit for absorption at any one time is based on studies of healthy subjects. However, research shows that animals that synthesize their own ascorbate produce 4-13 grams per day and can produce ten times that amount when stressed or sick. Therefore, taking Vitamin C is safe and not only encouraged but also beneficial.

Vitamin C and Immune Function

When it comes to the benefits of Vitamin C, it plays a crucial role in fighting against bacteria, viruses, and infections. In addition, it serves as an effective antihistamine, helping to reduce the symptoms of the common cold, such as inflammation, stuffy nose, and aches.

Supplements vs. Natural Sources

Eating foods rich in Vitamin C like fruits is beneficial for overall health. However, if you need to take a supplement, it is recommended to take powdered forms in doses of 200 mg frequently if you believe the dose of 1000 mg is necessary. Just remember, the effectiveness of high doses is not well-supported by research, and taking too much can lead to side effects like gastrointestinal issues and kidney stones.

Important Considerations

While Vitamin C is generally safe, it is always important to consult a doctor before starting or changing any treatment, especially if you have underlying health issues.
