From Scurvy to Skin Health: The Many Benefits of Vitamin C Revealed

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for various bodily functions. It acts as an antioxidant, helps in the synthesis of collagen, aids in immune function, enhances iron absorption, and helps repair tissues. Vitamin C cannot be synthesized by the human body, so it must be obtained from dietary sources like fruits and vegetables or supplements.

Manufacturing Process of Vitamin C

Starting Material: Vitamin C is most commonly synthesized from glucose (corn or wheat starch).
Fermentation: The starting glucose undergoes a fermentation process where specific microorganisms convert it into sorbitol.
Hydrogenation: Sorbitol is then hydrogenated to produce sorbose.
Oxidation: Sorbose is oxidized to form 2-keto-L-gulonic acid (KGA).
Cyclization and Synthesis: KGA is converted into ascorbic acid through chemical cyclization and acidification.
Purification: The resultant ascorbic acid is purified, crystallized, and dried for use in supplements.

Best Time to Take Vitamin C

Vitamin C is best taken in divided doses throughout the day, particularly with meals, as it helps improve absorption. The morning is a popular choice for many due to its immune-boosting properties. For those who need extra support, post-exercise may be another optimal time due to its role in muscle recovery.

Safety and Interactions with Medications

Vitamin C is generally considered safe for most individuals when taken in recommended amounts. However, high doses can cause certain side effects and interact with medications.

Interactions with Medications:

Chemotherapy Drugs: High doses of Vitamin C might reduce the efficacy of certain chemotherapy treatments by acting as an antioxidant and protecting cancer cells.
Statins: Vitamin C can affect the absorption and efficacy of cholesterol-lowering drugs.
Aspirin: Chronic use of aspirin can lower Vitamin C levels in the body.
Estrogen-containing Contraceptives: These can increase blood levels of Vitamin C, leading to potential toxicity if too much is supplemented.
Antacids: Some antacids may reduce the absorption of Vitamin C.
Warfarin (Blood Thinners): High doses of Vitamin C can decrease the efficacy of blood thinners, leading to clotting risks.
Proton Pump Inhibitors: These medications can lower Vitamin C levels by reducing stomach acid, which is necessary for its absorption.

Vitamin C Dosages for Children and Adults

The recommended daily intake of Vitamin C varies based on age, sex, and physiological conditions (such as pregnancy or breastfeeding).

Infants (0-6 months): 40 mg/day
Infants (7-12 months): 50 mg/day
Children (1-3 years): 15 mg/day
Children (4-8 years): 25 mg/day
Children (9-13 years): 45 mg/day
Adolescents (14-18 years, males): 75 mg/day
Adolescents (14-18 years, females): 65 mg/day
Adults (males): 90 mg/day
Adults (females): 75 mg/day
Pregnant women: 85 mg/day
Breastfeeding women: 120 mg/day

For individuals who smoke, it is recommended to increase Vitamin C intake by an additional 35 mg per day, as smoking depletes Vitamin C levels.

Side Effects of Vitamin C

While Vitamin C is safe in moderate doses, large doses (typically above 2,000 mg per day) can lead to side effects:

Gastrointestinal Upset: High doses can cause nausea, diarrhea, and abdominal cramps. To offset these symptoms, it is recommended to lower the dose or divide it throughout the day.
Kidney Stones: Excess Vitamin C can be converted into oxalates, which may form kidney stones in susceptible individuals. Staying hydrated and avoiding excessive doses can prevent this.
Iron Overload: Vitamin C enhances iron absorption, so people with conditions like hemochromatosis (excess iron) should be cautious. Monitoring iron levels and reducing Vitamin C intake can help manage this risk.
Acid Reflux: Large doses of ascorbic acid can exacerbate acid reflux in sensitive individuals. Taking buffered or non-acidic forms of Vitamin C (like sodium ascorbate) can help reduce this effect.

Vitamins and Minerals That Work Synergistically with Vitamin C

Vitamin E: Vitamin C regenerates oxidized Vitamin E, enhancing its antioxidant effects.
Zinc: Together, Vitamin C and zinc can boost immune function more effectively.
Iron: Vitamin C improves the absorption of non-heme iron, preventing anemia.
Glutathione: Vitamin C helps regenerate glutathione, an important antioxidant for cellular protection.
Vitamin B6: Vitamin C and B6 work together to maintain healthy immune function.
Vitamin A: The combination of Vitamins A and C supports skin health and wound healing.
Magnesium: Vitamin C enhances magnesium’s role in muscle function and reduces the likelihood of cramping.
Folate (Vitamin B9): Vitamin C works with folate in DNA synthesis and repair.

Overdosing on Vitamin C

Vitamin C is water-soluble, so excessive amounts are typically excreted in urine. However, consistently taking extremely high doses (over 2,000 mg/day) can cause the following:

Kidney Stones: As mentioned, high doses increase the risk of kidney stones in susceptible individuals.
Gastrointestinal Disturbances: Diarrhea, nausea, and stomach cramps can occur with excessive doses.
Iron Overload: Vitamin C enhances iron absorption, so excessive intake can lead to iron toxicity, particularly in individuals with iron overload disorders.
Oxalate Build-Up: Large amounts of Vitamin C can lead to increased oxalate in the urine, which can cause kidney stones.

How to Offset Overdosing:

Reduce Intake: Decrease the dose to below 2,000 mg/day or follow recommended guidelines.
Increase Hydration: Drinking plenty of water helps flush excess Vitamin C and reduce the risk of kidney stones.
Switch to Buffered Forms: Using a buffered form of Vitamin C can help minimize gastrointestinal side effects.
Monitor Iron Levels: If you are at risk of iron overload, regular blood tests can help manage your iron status when supplementing with Vitamin C.

This comprehensive overview of Vitamin C covers its production, health benefits, medical applications, potential deficiencies, interactions, and side effects. For optimal results, always follow recommended dosages and consider speaking with a healthcare provider, especially if taking Vitamin C in higher amounts or alongside medications.

Always consult your healthcare provider before starting any supplements, especially if you have underlying health conditions or are taking medications. Individual needs can vary, and your doctor can help ensure safety and effectiveness.
