Please take a lot of vitamins. For those who take comprehensive vitamins like Vitamin C and D, and for those who take minerals like calcium, magnesium, zinc, and copper, there are sudden side effects that occur and there are certain side effects that occur when taken for a long time. If you are aware of these, you can take supplements more healthily and consistently. I will summarize the characteristic side effects of vitamins and minerals. Hello, I'm a pharmacist from Yakdul Yak Pharmacy. First, let's cheer and get started. Fighting! Today, I will summarize the most common ingredients found in comprehensive vitamins, which are Vitamin A, B, C, D, E, K, minerals like calcium, magnesium, zinc, copper, selenium, and iron, and the most common side effects and precautions.

I have organized the information based on the protected data. I divided it into three categories. Firstly, short-term side effects, then long-term side effects to be cautious about, and finally, points to be aware of. Let me quickly go into it. First, I will talk about the ingredients that cause short-term side effects. Firstly, when consuming high doses of vitamin A, not the amount included in regular multivitamins, but high doses, most side effects occur. It is not beta-carotene, which is found in foods like vegetables; we usually consume beta-carotene as a dietary supplement, but retinol. Retinol, which turns into retinal, is usually consumed in doses of around 100,000 micrograms, which is the recommended daily intake.

You may not have a job that requires such a high dose, but some people occasionally take it to improve things like acne. When they take a high dose, side effects can occur within a week to up to four weeks. The typical side effects include headaches, nausea, blurred vision, pain in muscles or joints, a sudden increase in liver enzymes, increased pressure in the brain and even odd states. The most common side effect is yellowing of the skin, nails, and whites of the eyes. Unless you take vitamin A separately, exceeding the dosage is not common, so there's no need to worry too much. However, some people used to take around 100,000 units, so if you take high doses, you should be a bit careful.

Usually, about 3,000 units of comprehensive vitamins are included. It's not necessary to worry too much because it's a high dosage, so extreme short-term side effects occur. I found cases like this. Secondly, when taking a high dose of vitamin D, as I mentioned before, when you consume too much vitamin D, it burdens the kidneys. Most side effects occur due to incorrect dosage. In the case of high dosage, side effects occur when consuming around tens of thousands of units a day. For example, if you take 300,000 units at once for a month's worth, these kinds of cases. So, when consuming too high a dose of vitamin D, occasional side effects may occur, such as gastrointestinal disorders, headaches, dizziness, followed by kidney failure on the renal side, hypercalcemia, and...

Absences have occurred, such things have happened, but usually when consumed in appropriate amounts, there were hardly any issues. I would like to say this. Thirdly, a vitamin component that shows toxicity in a short period is niacin, vitamin B3. Even in low doses, it hardly causes any problems. In multivitamins, usually, about 100mg is included, but toxicity occurs when consumed over about 1,000mg. Niacin is often consumed separately for the purpose of improving cholesterol. When taken separately, toxicity most commonly occurs when consumed between 1,000mg and 3,000mg. It has shown symptoms such as skin itching, numbness in hands and feet, low blood pressure, and kidney toxicity. Similarly, the issues that arise when consumed in high doses. Fourthly, a mineral component that shows toxicity in a short period is iron. Iron, iron, if you consume iron for a long time.

Eating it's not allowed, and if you take iron, it accumulates. Some people say you should eat or not eat it, right? Usually, acute toxicity of iron occurs when you ingest more than 20mg of iron per 1kg of body weight, which can lead to serious toxicity. So, if you weigh 60kg, you need to consume 1200mg of iron per day to reach a certain level. However, the recommended intake of iron is around 20mg, with a maximum limit of about 40mg. Eating about 60 times the recommended amount, like this, is not something you do daily. When you consume the appropriate amount of iron, your body regulates it in the intestines, excretes it through feces, absorbs it, and adjusts it, so there are no issues, and you can steadily consume it. Therefore, don't worry too much. In the case of iron, even if your hemoglobin levels are normal or your ferritin levels are normal, you may experience dizziness or fatigue.

Women with digestive issues, headaches, menstrual pain, and so on can benefit greatly from taking care of themselves. Therefore, you don't need to worry about eating. I'm telling you that side effects only occur in high doses. Side effects can occur within a short period, from 2 to 4 weeks. Inflammation in the intestines, intestinal damage, and even shock-induced unconsciousness can occur. The most common short-term side effects caused by vitamins and minerals are usually headaches, gastrointestinal disorders, nausea, abdominal pain, constipation, diarrhea, etc., excluding these, there are almost no side effects. These are the uniquely occurring short-term side effects caused by vitamins and minerals. This is how you should see it. Next, in the second part, when taken chronically for a long time, more than 3 to 6 months, the side effects of vitamins and minerals occur.

Let me tell you about some unusual things. First, vitamin B6, pyridoxine. Regarding pyridoxine, I mentioned that neurotoxicity can occasionally occur. When I looked up the data, side effects typically occurred when consuming over 200mg, and the recommended upper intake level is set at 100mg. Foreign data showed side effects occurring with over 200mg, so as a safety measure, it's advised to only consume half. In some cases, side effects appeared when consuming around 1000mg daily for about 6 months. These side effects include sensory peripheral neuropathy, numbness or tingling sensations, weakness in the limbs, imbalance, dizziness, or ear problems due to neurotoxicity. However, in some cases, side effects occurred at a much lower dosage of 50mg than the recommended upper limit.

Some say they have acne even after eating, usually occurring in older people, women, and those who are more sensitive. Normally, it occurs with a dosage of over 200mg. In some cases, there is data showing an increased risk of hip fracture in elderly people who consume around 40mg daily for over three years. So, that's about it. When consumed in appropriate amounts, there shouldn't be a problem, and for pyridoxine, the usual maximum intake is set within 100mg, even for imported products. So, there's no need to worry. However, there are cases where people take two Vitamin B tablets simultaneously, like taking a multivitamin and another 100mg of Vitamin B separately, totaling 200mg. In such cases, caution is required. I would like to mention that these are not short-term side effects but can occur when taken for over six months.

Don't worry too much even if I eat about 200mm due to side effects. It hardly occurs. Second, there is zinc. In the case of zinc, side effects occur when the intake exceeds the daily limit of 40mm. Most side effects occur because zinc and copper competitively interfere with absorption. So, if a lot of zinc is taken, copper absorption is hindered, and if a lot of copper is taken, zinc absorption is hindered. Therefore, if you consume too much zinc, copper deficiency occurs, leading to most side effects. So, short-term side effects are unlikely because copper deficiency does not occur in the short term. Therefore, when high doses of zinc are consumed for a long time, side effects occur, which usually include decreased immunity, the formation of ulcers, the onset of cardiovascular diseases, dizziness, and neurological symptoms.

Therefore, it is said that mood and cognitive abilities have declined. To reduce these side effects, it is recommended to consume about 1mg of copper per day. Most multivitamins or mineral supplements such as calcium and magnesium contain copper, so even if you consume a high amount of zinc, there is likely no need to worry. However, for those who are sensitive to copper, it is important to check the dosage. Next, thirdly, is calcium. In the case of calcium, there may be gastrointestinal disorders, but when consumed in high doses for a long time, typically over 1mm for several years, the risk of stroke and cardiovascular diseases increases. Also, the risk of kidney stones increases. This is due to the calcium paradox.

Calcium doesn't get properly absorbed, so it floats in the bloodstream, leading to osteoporosis and various cardiovascular diseases. Therefore, it is necessary to take calcium and magnesium together, and also vitamin K2. These calcium paradox situations usually do not occur in the short term but after consuming calcium for several years. Lastly, rather than side effects, there are some ingredients to be cautious about, such as vitamin B7, biotin. Biotin is recommended for preventing hair loss and maintaining nail health, with a daily intake of 5 to 10. Some people take doses from thousands to tens of thousands, which can lead to issues during health check-ups. High doses are usually taken when testing the thyroid.

Disturbing the numbers, whether it is when conducting a prostate cancer screening or when examining myocardial infarction, can cause accidents. Therefore, those who take high doses of biotin should always keep this in mind. Usually, for those who take low doses, around 30 to 100 or less, there is no need to pay special attention. However, for those who take high doses, around 5,000 to 10,000, they should stop taking it a day before the test so that biotin is excreted. And for those who take really high doses, around 100,000, it was stated that they should stop taking it 3 to 4 days before the test. Today, we looked at precautions regarding vitamins and minerals that are commonly included in comprehensive supplements. It may be a common topic, but since many people take them, it would be good to remember it as a reminder. If today's video was helpful, please like and subscribe.

I would appreciate it. Thank you. Goodbye.

약사가 들려주는 약 이야기

Short-Term and Long-Term Side Effects of Vitamin A

High doses of vitamin A can cause short-term side effects like headaches, nausea, and blurred vision.

Long-term use of high doses of vitamin A may lead to more serious effects such as liver damage and increased pressure in the brain.

It's important to be cautious when taking vitamin A supplements, especially in doses exceeding the recommended daily intake.

Potential Short-Term Toxicity of High-Dose Vitamins and Minerals

High doses of vitamin D can cause short-term side effects and kidney burden, especially when consuming tens of thousands of units a day.

Niacin (vitamin B3) can also show toxicity in low doses, leading to symptoms like itching and numbness, while iron can cause acute toxicity when ingested in high amounts, despite the body's regulation ability.

The Impact of Vitamin and Mineral Consumption on Women's Health

Women can benefit from taking care of their digestive issues, headaches, and menstrual pain through appropriate vitamin and mineral consumption.

Short-term side effects of vitamins and minerals can include inflammation in the intestines, gastrointestinal disorders, and headaches, while long-term use, especially of vitamin B6, can lead to neurotoxicity and increased risk of hip fracture in the elderly.

The recommended upper intake level of vitamin B6 is set at 100mg, and exceeding this can lead to various side effects, so caution is advised, especially for women and older individuals.

The Impact of Excessive Zinc and Calcium Intake

Excessive zinc intake can lead to side effects due to competitive interference with copper absorption, causing decreased immunity and neurological symptoms in the long term.

Consuming 1mg of copper per day is recommended to reduce these side effects, with most multivitamins containing copper.

High and prolonged calcium intake can increase the risk of stroke, cardiovascular diseases, and kidney stones due to the calcium paradox, but this usually occurs after several years.

Biotin, when taken in high doses for thyroid testing, can cause issues during health check-ups, despite its recommended daily intake for preventing hair loss.

Precautions for High-Dose Biotin Intake Before Medical Tests

High-dose biotin intake can interfere with medical test results for prostate cancer and myocardial infarction.

Low doses of biotin (30 to 100 mcg or less) generally don't require special attention before tests, but high doses (5,000 to 10,000 mcg) require stopping intake a day before, and very high doses (100,000 mcg) require stopping 3 to 4 days before.

These precautions are important for people taking comprehensive supplements, as high biotin levels are common and can impact test accuracy.
