Anyone in cancer treatment should ask their oncologist first. <a href="https://ods.od.nih.gov/factsheets/VitaminC-HealthProfessional/" target="_blank" rel="noopener">ODS also flags</a> a study where antioxidants blunted a statin and niacin combination, and warns that high doses worsen iron overload in hemochromatosis. <a href="https://www.nccih.nih.gov/health/using-dietary-supplements-wisely" target="_blank" rel="noopener">Tell every clinician what you take</a>.</p></div><div class="plan" id="coach-recommendations"><div class="pt">📋 Your Coach's Recommendations</div><div class="step"><div class="n">1</div><div><div class="sh">Check your food before your cart.</div><div class="sd">Two servings of citrus, peppers, kiwifruit or broccoli in a day clears the requirement outright.

Buy it if you like it; do not buy it expecting a different result.</div></details><details><summary>Is 1,000 mg a day dangerous?</summary><div class="a">It is under the 2,000 mg adult ceiling, so it is not dangerous for most people, but it is wasteful. <a href="https://www.ncbi.nlm.nih.gov/books/NBK225480/" target="_blank" rel="noopener">The dietary reference intake report</a> describes absorption falling away as single doses climb past a gram, with the surplus excreted. Diarrhea and stomach cramps arrive before any benefit does.</div></details><details><summary>Can it cause kidney stones?</summary><div class="a">High doses are the concern, not ordinary intake, and the risk signal is strongest in men with a stone history. Anyone who has had a stone, or who has hemochromatosis, should ask a clinician before taking a single ingredient vitamin C capsule, and <a href="https://ods.od.nih.gov/factsheets/WYNTK-Consumer/" target="_blank" rel="noopener">supplements are not reviewed by the FDA for effectiveness before sale</a>, so an independent test seal is the floor.</div></details></div><div class="src-list"><h3>Sources</h3><ul><li><a href="https://ods.od.nih.gov/factsheets/VitaminC-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Vitamin C, Fact Sheet for Consumers</a></li><li><a href="https://ods.od.nih.gov/factsheets/VitaminC-HealthProfessional/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Vitamin C, Fact Sheet for Health Professionals</a></li><li><a href="https://medlineplus.gov/ency/article/002404.htm" target="_blank" rel="noopener">MedlinePlus Medical Encyclopedia: Vitamin C</a></li><li><a href="https://medlineplus.gov/ency/article/000355.htm" target="_blank" rel="noopener">MedlinePlus Medical Encyclopedia: Scurvy</a></li><li><a href="https://www.ncbi.nlm.nih.gov/books/NBK225480/" target="_blank" rel="noopener">NIH National Library of Medicine: Dietary Reference Intakes for Vitamin C</a></li><li><a href="https://ods.od.nih.gov/factsheets/list-VitaminsMinerals/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Vitamin and Mineral Supplement Fact Sheets</a></li><li><a href="https://ods.od.nih.gov/factsheets/WYNTK-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements: Dietary Supplements, What You Need to Know</a></li><li><a href="https://www.nccih.nih.gov/health/using-dietary-supplements-wisely" target="_blank" rel="noopener">NCCIH: Using Dietary Supplements Wisely</a></li><li><a href="https://www.nccih.nih.gov/health/tips/tips-natural-products-for-the-flu-and-colds-what-does-the-science-say" target="_blank" rel="noopener">NCCIH: Natural Products for the Flu and Colds, What Does the Science Say</a></li></ul></div><div class="ac-sig"><div class="rule"></div><p class="toyour">To your health,</p><svg width="320" height="72" viewBox="0 0 320 72" role="img" aria-label="Ageless Coach.
