1. What Is The Recommended Daily Intake Of Vitamin C For Men?

The recommended daily intake (RDI) of vitamin C for men is 90 milligrams (mg) per day. This amount is generally sufficient to prevent deficiency and maintain overall health. However, individual needs may vary based on factors such as age, lifestyle, and health conditions.

General Health: 90 mg per day is adequate for most men.
Smokers: Smoking depletes vitamin C levels, so smokers may require 35 mg more per day, totaling 125 mg.
Athletes: Intense physical activity can increase oxidative stress, potentially increasing vitamin C needs. Consult with a healthcare provider for personalized recommendations.
Underlying Conditions: Men with certain medical conditions may need higher doses of vitamin C under medical supervision.

2. What Are The Health Benefits Of Vitamin C For Men?

Vitamin C is essential for numerous bodily functions. Here are some key health benefits for men:

Immune System Support: Vitamin C boosts the immune system by enhancing the function of white blood cells, which help fight off infections.
Antioxidant Protection: As a potent antioxidant, vitamin C neutralizes harmful free radicals, reducing oxidative stress and protecting cells from damage.
Collagen Production: Vitamin C is crucial for collagen synthesis, a protein essential for skin, tendons, ligaments, and blood vessels.
Heart Health: Studies suggest that vitamin C may help lower blood pressure and reduce the risk of heart disease.
Iron Absorption: Vitamin C enhances the absorption of non-heme iron from plant-based foods, which is particularly beneficial for vegetarians and vegans.

3. What Happens If A Man Consumes Too Much Vitamin C?

While vitamin C is generally safe, excessive intake can lead to several adverse effects. The tolerable upper intake level (UL) for vitamin C is 2,000 mg per day. Consuming more than this amount can cause:

Digestive Issues: Diarrhea, nausea, abdominal cramps, and bloating are common side effects of high doses.
Kidney Stones: Excessive vitamin C can increase oxalate levels in the urine, raising the risk of kidney stone formation, especially in individuals prone to kidney problems.
Iron Overload: Vitamin C enhances iron absorption, which can be problematic for individuals with hemochromatosis (iron overload disorder).
Drug Interactions: High doses of vitamin C can interfere with certain medications, such as blood thinners and statins.
False Medical Test Results: High intake may affect the accuracy of glucose monitoring and other lab tests.

4. What Are The Best Food Sources Of Vitamin C For Men?
