The body absorbs it limitedly: at a dose of up to 100–200 mg at a time, up to 90% is absorbed, while any excess is simply excreted. Therefore, large doses (1000–2000 mg) are often useless and can even be harmful — they increase the risk of kidney stones and cause gastrointestinal disorders.

What is Important to Remember

• It is better to take it in divided doses: 100 mg 2–3 times a day
• Avoid combining it with large amounts of sugar — it reduces absorption
• Absorption worsens with intestinal problems
• The daily norm is approximately 70–100 mg

What to Combine and Not to Combine With

Beneficial:

• with iron — improves its absorption

• with vitamin E — enhances the antioxidant effect

Cautiously:

• with certain antibiotics (tetracyclines, etc.)

• in cases of excess iron in the body

Main Conclusion: Vitamin C works better in small doses and with regular intake, rather than in the form of "shock" doses.
