Manee Vita C+ Vitamin C 1000mg Glutathione – 30 Sachets Skin Brightening & Immune Support Thailand

Key Information about Vitamin C (Ascorbic Acid):

• Water-soluble Vitamin: Vitamin C is a water-soluble vitamin, meaning your body doesn’t store it. Excess amounts are typically excreted in urine. This is why daily intake is often recommended.
• Antioxidant: Vitamin C is a powerful antioxidant, which means it helps protect your cells from damage caused by free radicals. Free radicals can contribute to chronic diseases and aging.
• Collagen Production: It’s essential for the synthesis of collagen, a protein vital for healthy skin, blood vessels, bones, cartilage, gums, and teeth, and for wound healing.
• Immune System Support: Vitamin C plays a crucial role in maintaining a healthy immune system. Some studies suggest it can help reduce the duration and severity of common colds, especially in individuals under extreme physical stress.
• Iron Absorption: It enhances the absorption of non-heme iron (iron from plant-based foods), which is particularly beneficial for those with a primarily plant-based diet.
• Other Potential Benefits: Research suggests potential benefits for managing blood pressure, lowering the risk of heart disease, preventing gout, and supporting eye health (like reducing the risk of cataracts and age-related macular degeneration).

Potential Benefits of a 1000mg Dose:

A 1000mg dose of Vitamin C is considered a high dose. While the Recommended Daily Allowance (RDA) for adults is much lower (e.g., 75mg for women, 90mg for men), higher doses are often taken for specific purposes, such as:

• Boosting immunity during cold and flu season.
• Supporting recovery during periods of high physical stress.
• Addressing specific deficiencies or health concerns under medical guidance.

Important Considerations and Potential Side Effects:

• Tolerable Upper Intake Level (UL): The established Tolerable Upper Intake Level (UL) for Vitamin C in adults is 2,000 mg per day. Exceeding this limit regularly can lead to side effects.
• Digestive Issues: The most common side effects of high-dose Vitamin C are digestive discomfort, including diarrhea, nausea, stomach cramps, and heartburn. These are more likely with doses exceeding 2,000 mg at once.
• Kidney Stones: In some individuals, particularly those prone to kidney stones, high doses of Vitamin C can increase the risk of oxalate kidney stone formation.
• Iron Overload: While Vitamin C aids iron absorption, individuals with conditions like hemochromatosis (a disorder that causes excessive iron accumulation) should be cautious with high doses, as it could lead to iron overload.
• Interactions with Medications: Vitamin C can interact with certain medications, including:
  • Aluminum-containing medications: May increase aluminum absorption, harmful for kidney problems.
  • Chemotherapy drugs: Potential concern that antioxidants like Vitamin C might reduce their effect.
  • Estrogen: May increase estrogen levels when taken with oral contraceptives or hormone replacement therapy.
  • Protease inhibitors: May reduce the effect of these antiviral drugs.
  • Statins and niacin: May reduce the effects of these cholesterol-lowering drugs.
  • Warfarin (Jantoven): High doses might reduce the effectiveness of this anticoagulant.
