The human body requires only tiny, often microgram-level, amounts of vitamins and minerals to function properly, classifying them as 'micronutrients'. It is a common and dangerous misconception that taking large, or 'mega,' doses of these nutrients offers greater health benefits, when in reality it can lead to toxic effects.

The body tightly controls vitamin C levels through a saturation-based absorption process. While small, dietary doses are absorbed with high efficiency, this absorption rate decreases significantly as intake increases.

According to poison control data, tens of thousands of vitamin exposure cases are reported annually in the U.S., highlighting the widespread risk of overconsumption. Among various practices, taking high-dose supplements, especially of fat-soluble vitamins over a prolonged period, is the most direct and common cause of vitamin toxicity, also known as hypervitaminosis. Unlike water-soluble vitamins that are typically excreted, fat-soluble vitamins are stored in the body's tissues, leading to a dangerous buildup.

According to reports, poison control centers in the U.S. received over 42,000 calls related to vitamin exposures in children alone in 2021, highlighting the real-world dangers of excessive intake. It is a misconception that more vitamins are always better, and many common practices can lead to vitamin toxicity.

The human body cannot produce its own vitamin C, making regular dietary intake essential for proper function. The question of 'is high C good for you' is more complex than a simple yes or no, requiring a look at the difference between adequate intake and excessive megadosing.

Vitamins and minerals are essential nutrients that your body needs in very small amounts to work properly and stay healthy. The statement that vitamins are required in large quantities for normal bodily function is false, and consuming excessive amounts can pose health risks.

The Tolerable Upper Intake Level for vitamin C in adults is 2,000 milligrams (2g) per day, making the prospect of trying to get 100g of vitamin C not only unnecessary but extremely dangerous. This is a pharmacological dosage level, not a nutritional one, and attempting it without strict medical supervision can lead to severe health consequences, including organ damage.

The Tolerable Upper Intake Level (UL) for adults has been established at 2,000 mg of vitamin C per day to prevent adverse side effects from excessive consumption. While the vitamin is often considered very safe, exceeding this threshold, particularly through supplements, can lead to uncomfortable or serious health problems for certain individuals.

According to Harvard Health, taking too much vitamin C, typically over 2,000 mg per day, can cause unpleasant side effects such as nausea, diarrhea, and stomach cramps. If you've ever asked, 'Why do I feel worse when I take vitamin C?', the answer often lies in dosage, timing, and individual sensitivities, not a paradox of the nutrient itself.

Statistics show that a significant portion of the population, including many Americans, regularly takes some form of vitamin or mineral supplement. This widespread practice raises a crucial question: are vitamins and minerals helpful or harmful, and where is the line between benefit and risk?
