4. Analysis of 3 VC myths that have been hotly debated recently
1."VC tablets can replace fruits" controversy: Nutrition experts point out that although VC tablets can quickly supplement vitamins, synergistic nutrients such as bioflavonoids and dietary fiber in fruits cannot be replaced. It is recommended that the daily intake of VC tablets should not exceed 500mg, and the rest should be supplemented through fruits and vegetables.
2."High dose VC when you have a cold" effect: The latest clinical data shows that high-dose VC may shorten the course of the disease by 10% only in the early stages of a cold (within 24 hours), and daily preventive supplementation is more effective than surprise supplementation.
3."VC whitening needs to avoid light" statement: Studies have found that VC does not need to be protected from light to function in the body, but VC skin care products for external use do need to be stored away from light. The whitening effect of oral VC requires continuous supplementation for 2-3 months to take effect.
5. Guide to purchasing and consuming VC tablets
1.Dosage form selection: The absorption rate of ordinary tablets is about 70%, and the absorption rate of sustained-release tablets is up to 90%, but the price is 2-3 times higher. Chewable tablets are suitable for children, but effervescent tablets need to pay attention to the sodium content.
2.Ingredient screening: Prefer complex formulas containing bioflavonoids and avoid products with added sugar and pigments. The absorption rate of naturally extracted VC (such as from acerola cherry) is 20% higher than that of synthetic VC.
3.Contraindications: Patients with kidney stones should not take more than 200mg per day; those who are taking anticoagulant drugs should take an interval of 2 hours; patients during chemotherapy are prohibited from taking high doses of VC.
4.Save method: VC is prone to oxidation and failure. It should be sealed and stored in a cool place away from light. It is recommended to use it within 3 months after opening.
Conclusion:Vitamin C is a water-soluble vitamin, and proper supplementation can indeed bring multiple health benefits. However, according to recent health big data, about 35% of VC supplementers in my country have overdosed or improperly used it. It is recommended to develop a personalized supplement plan after professional nutrition assessment, so that VC tablets can truly become a help rather than a burden for a healthy life.
