Root cause of the whole saga: the Beehiiv subscribe form is a cross-origin iframe
we cannot restyle, and its interior is white, so it can never sit cleanly on the
navy plan card. Answer: change the surface, not the form. Both live states render
on ONE light Ocean Fog panel, the same surface the 219 live articles already use.
No trigger step: the field is visible on load per the v7.0 lock. Article-side
only, zero Beehiiv dependence. Every state shares one look.
DO NOT re-add border-radius or overflow:hidden to .capform: a rounded clip slices
the embed's own pill outline and leaves a visible break at the left end. On a light
panel the clip buys nothing, because there is no artifact left to hide. */

<p class="b">The <a href="https://ods.od.nih.gov/factsheets/VitaminC-Consumer/" target="_blank" rel="noopener">NIH Office of Dietary Supplements</a> says most people here get enough vitamin C from food and drinks. It also says a real shortage is rare in the United States and Canada.</p>
<p class="b">That is the line the shelf never prints. A whole aisle is built on a gap that most shoppers do not have.</p>
<p class="b">Fruit and vegetables are the best sources. Citrus fruit and its juice, red and green pepper and kiwifruit carry a lot. Broccoli, strawberries, melon, baked potato and tomato carry some.</p>

<div class="inner"><div class="big">2</div><h3>The people who genuinely run short</h3></div>
<p class="b">There is a real list and it is short. People who smoke, or who live with smoke, because smoke raises how much the body needs. People who eat a very small range of food. And people with some health conditions, such as poor gut absorption, some cancers, and kidney disease that needs dialysis.</p>
<p class="b"><a href="https://medlineplus.gov/ency/article/002404.htm" target="_blank" rel="noopener">MedlinePlus</a> adds that people who are pregnant or nursing need more. It says to ask your provider what amount is right for you. It also notes that the body cannot make vitamin C and does not store it. That is why it has to arrive most days.</p>
<p class="b">If none of those fit you, the honest answer is that your plate is already doing the work.</p>

<p class="b">Too much brings loose stools, nausea and stomach cramps. Very high intakes can rarely lead to kidney stones. And in hemochromatosis, which makes the body store too much iron, high doses can make that worse.</p>
<p class="b">The upper limit is the part people miss. It counts every source, food and drinks as well as pills. So a fortified drink and a multivitamin are already on your tally before you open a new bottle.</p>
<p class="b">The <a href="https://www.nia.nih.gov/health/vitamins-and-supplements/dietary-supplements-older-adults" target="_blank" rel="noopener">National Institute on Aging</a> puts the rest of it plainly. Do not assume more is better. Too many pills, or one nutrient at a very high strength, can do harm. Research so far suggests large doses of antioxidant pills will not prevent chronic disease. And the FDA does not approve supplements for safety or benefit before they are sold.</p>

<h2>Frequently Asked Questions</h2>
<details><summary>Who actually needs a vitamin C supplement?</summary><div class="a">A short list. People who smoke or live with smoke. People who eat a very small range of food. And people with some health conditions, such as poor gut absorption, some cancers, or kidney disease that needs dialysis. The plan prints the list, so you can rule yourself in or out in a minute.</div></details>
<details><summary>Can you take too much vitamin C?</summary><div class="a">Yes. Too much brings loose stools, nausea and stomach cramps, and rarely kidney stones. There is a daily upper limit. It counts food, drinks and pills together, not pills alone. The number is on the printable plan.</div></details>
<details><summary>Does vitamin C stop a cold?</summary><div class="a">No. For most people, a supplement does not lower the risk of catching a cold. People who take one every day may have slightly shorter or milder colds. Starting one after symptoms begin does not seem to help.</div></details>
<details><summary>Who should ask a health professional first?</summary><div class="a">Anyone in cancer care, because antioxidant pills may clash with chemo and radiation. Anyone on a statin plus niacin, since one study saw the heart benefit fall. Anyone with hemochromatosis. The label also warns against use if you have ever reacted to any of the ingredients, says it is not for use during methotrexate cancer therapy, and says not to use it if you are pregnant, trying to conceive or nursing.</div></details>
