The recommended daily allowance is 700 micrograms for women and 900 micrograms per men. The UL is 3,000 micrograms per day. Regularly consuming more than this amount may cause hair loss, cracked lips, dry skin, headaches, and weakened bones.
The Tolerable Upper Intake Level (UL) for adults is 3,000 mcg RAE (Table 2). It would be difficult to reach this level consuming food alone, but some multivitamin supplements contain high doses of vitamin A. Retinol is the form of vitamin A that causes the greatest concern for toxicity.People are generally advised to avoid exceeding the upper limit of vitamin D intake, which is 4,000 IU per day for adults. Higher amounts, ranging from 40,000–100,000 IU (1,000–2,500 mcg) per da.

Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects. RDAs for vitamin A are given as retinol activity equivalents (RAE) to account for the different bioactivities of retinol and provitamin A carotenoids, all of which are converted by the body into retinol (see Table 1).The UL (Tolerable Upper Intake Level) is the maximum amount of daily vitamins and minerals that you can safely take without risk of an overdose or serious side effects.

Hey dude, Your videos are amazing!!! How about we do a Sub For Sub? It would be amazing for both of us. Reply me if you’re interested.
NICE Video… I Subbed you, pls SUB back!
Let’s support each other. CHECK OUT MY CHANNEL.
I’m so glad you spent some time to explain the difference between VB12 and VE deficiency in terms of neuro signs. I have been fooled like this on practice questions and it’s so frustrating!!! Very helpful, thank you:)
i read the axact same infornatikn described in the exact se way on an article
We must supplements. We don’t get enough minerals from foods because the minerals are not in the soil anymore. Furthermore, we need 90 essential nutrients. 60 minerals, 16 vitamins, 12 amino acids and 2 essential fatty acids but they are not all present in foods. Some are, most are not. This is why Youngevity is a must have product as Dr. Peter Glidden confirm.
this dont help. our pee holds the extra stuff our bodies dont use so technically too much vitamins of a certain kind won’t do much to u either. it makes ur pee neon yellow like a piss glow stick
Eating liver multiple times a week…I’m just a hypervitaminosis A ticking time bomb. I’ve got the being-a-hypervitaminosis-A-ticking-time-bomb-blues!
Food for thought! Good attitude and thanks for your observation.
Damn I thought this dude died on Captain Hook’s ship 25 years ago. Glad to see he’s alive and well.
So if I cut the vitamin in half and take it daily (men’s “one a day” ) will it be better than taking the entire pill everyday??
Scishow, could you please make a video about elderberry syrup? I live in an area where everybody swears by it, and not just holistic people.
I doubt most people, even people into fitness have a balanced diet. I was never a picky eater but ended up with Vitamin D deficiency (hair falling out, more fragile teeth, worse vision) and even an iron deficiency. This happened even with my habit of eating salads, veggies, and beans every day.
Vitamin D supplements helped with the hair, but still not fully cured. And let’s be frank, most veggies ppl eat are too processed and cooked in incorrect ways to yield them the right dose of these vitamins.
Okay, but my food stamps ran out so my diet has been poor, so if you can’t get enough of certain vitamins from your food will taking a supplement give it to you in a form that your body can use? I know that it doesn’t matter if you actually get it from your diet, but I’m asking about a scenario in which you don’t.
I bought multi men’s vitmin’s and they Stink like really really bad
There’s so much more to vitamins and supplements than this video leads you to believe.
My VitaminD level is low my doctor prescribed me 50,000 I just started taking multivitamins and now laying out in direct sunlight for 15-20 minutes to get my VitaminD level up. I always thought multivitamins were good to take.
Ever since I started taking multivitamins, I haven’t gotten as sick. So I highly recommend taking them during the Coronavirus Pandemic.
I was born with multiple deficiencies and vitamins, and food it doesn’t exactly give me all of the vitamins that I need. So, in my case multivitamins are incredibly crucial.
Why would I take an a medical advice from a guy with a goatee and a bad hair cut?
i dont follow. if youve got a shit diet so you take multivitamins how is that a bad thing. how is that gonna hurt you if you dont overdose? how is that not going to help
I think they definitely get absorbed if not as efficiently as vitamins in food. Definitely some multivitamins are imporoperly manufactured but to dismiss multivitamins as a whole seems to be a reactionary news based response. It’s a lot more shocking to say multivitamins are a lie rather than explain they may be overkill etc. say, instead of daily weekly? Every other week? Outright dismissal seems wrong.
say what you want but my skin nails and hair got alot better after using muti vitamins and I feel less fatigue.
Is it true that if you eat sea food combined with orange juice (or vitamin C) you can intoxicate yourself with arsenic because this combination in your stomach creates arsenic trioxide (As2 O3) which is what we call arsenic?
you guys better off watching a reputable advise from dr oz videos than this. he recommends taking multivitamin as in today’s busy life nobody will be able to eat perfectly balance diet.
I liked the old way then there was music on the end of video, now there is always some talk from an episode that I already watched.
most studies show the average americn deficient in vitamin A, vitamin C, and magnesium. Vitamin A deficiency: Deficiency impairs immunity and hematopoiesis and causes rashes and typical ocular effects (eg, xerophthalmia, night blindness). Vitamin C deficiency: Signs of vitamin deficiency include dry and splitting hair; gingivitis (inflammation of the gums) and bleeding gums; rough, dry, scaly skin; decreased wound-healing rate, easy bruising; nosebleeds; and a decreased ability to ward off infection. A severe form of vitamin C deficiency is known as scurvy. Magnesium deficiency: the symptoms of low magnesium in the body? Calcification of the Arteries. Though this is not (hopefully) the first symptom of magnesium deficiency, it can be one of the most dangerous…. Muscle Spasms and Cramps…. Anxiety & Depression…. High Blood Pressure/Hypertension….

I guarantee you, at least in the U.S, the vast majority are vitamin deficient, just look outside 1/3rd are obese, 3/4 men are overweight (yes you read that right 74% of American men are overweight), and you really think most people eat a “balanced diet”..
Ty just saved me $20 I was debating on whether or not to invest in vegan multivatimins
My mom has some health issues. She watches yahoos on youtube and makes her own ideas. I keep telling her, trust your doctor!
You need a blood test to show if you are overdosing or underdosing. But since you’re just trying to get views you wouldn’t state this.
I have a bottle of iron supplements in my medicine cabinet. Each pill has 65mg of iron 361% of your daily value.
I remember a couple years ago, I took one every day for three days straight. I practically felt like I was going to die on that third day.
Now I only take one of those supplements when I know I need one.
Literally just bought multivitamins before watching this vid.Great waste of money
I eat rice and chicken every single day I might have deficiencies
I don’t know why every time i take a multivitamin such as GNC sport or centrum i get agitated and my OCD hits the roof!؟
You need to take vitamin C. You must if you live in a city or if you are smoker/alcohol drinker. You need to get some vitamin K and D, also Mg, K, Cr, Fe, and more… Most natural sources (soil) are depleted. BUT, you should consult it with your physician.
how do i know if im lack of some kind of vitamin?:( am i going to die soon? or live a painful life?:((
Would it make sense to take a 500mg Vitamin C supplement every 4 days, since 125mg is slightly higher than 25% of the RDA?
He assumes that everyone has a well-balanced diet. Most people have horrific diets, therefore multivitamins can help.
Huge fan of SciShow. Disappointed in this episode that there was no mention of recent research showing that gut bacteria appears to be partially responsible for people absorbing vitamins at different rates. Blood tests are one way for people to find out how much of the RDA a person is actually absorbed for use by the body.
many vitamins have additional benefits that can be gained by consuming more than the 100% RDI, and some of those RDI’s are being shown to probably be too low, like vitamin D.
You can’t listen to a doctor’s recommendations these days because all of them tell you to take a multivitamin daily even with a balanced diet. That’s one reason I switched doctors my previous physician was old school and (I believe) suggested treatments, medications or products that I never needed.
it’s a little disturbing that they didn’t mention the multiple studies that show taking vitamins are bad for you.
Vitamins are great I been taking centrum gummies I feel my amune system stronger and help concentrate
lul im sure a multivitamin is bad for us when the vast majority of us don’t get the proper nutrients in our diets……..(sarcasm)
I have thalassemia and I hate red meat. I don’t take multivitamins everyday but when I do I take kids multivitamins. Does anyone know if that’s bad???
My concern is to replenish any other vitamins that contain in Multi Vitamins. I might get enough dosage those mentioned Vits in my food but how about others? Eg Calcium, Iron, Folic Acid etc?
+SciShow follow up QQ: is it viable for you to just take the RDV of all the vitamins you need instead of eating.
Vitamins are best for people with malabsorption who don’t get enough vitamins from food. Best practice is to have a blood test before taking any vitamins.
if i eat frozen pizza and take a multivitamin how is that not winning???
Show me one multivitamin that has more then 100% of the RDA of any of its components. I’ve yet to see one. Where are you getting this nonsense?
This has always been a question of mine about if vitamins are really good for you or unnecessary for some people. The truth is they are unnecessary to some who think they need to take them. I understand there are people that for whatever reason are deficient in some vitamins, common ones like vitamin D or vitamin C but without being told that you are deficient in these, you should not take vitamins. Annual physicals tell you whether you are in need of certain vitamins, nutrients and many other things, so don’t play doctor and take it upon yourself to take vitamins when there is no need. Fat-soluble vitamins are the ones that you should be concerned about physically. Water-soluble are not as big of a deal because like he said, you just pee those out where as the fat-soluble vitamins can build up and cause a toxicity. Those that take vitamins without the consultation with a doctor are just wasting money and putting themselves at risk for vitamin toxicity.
GEEZ, I bought orange triad multivitamins, if I take 1 serving (6 tablets) it is 10000% DV of b12, WTF DID I BUY?
Why does everyone who makes these types of videos sound like the dude from Crash Course
Correction. “For healhty dwarves or women ” That’s not 100% of all people.
THE KEY IS ONLY AND ONLY LAB BLOOD TEST FEED BACK, YOU MUST UPHOLD YOUR D3 WHICH ARE TWO COMPOUNDS PHOTO COLECALCIFEROL (WHICH ASWELL DISSOLVES IN WATER AND COMES FROM SUN) AND LIPID COLECALCIFEROL (COMES FROM OILS) IN A MANNER THAT YOUR 25 OH COLECALCIFEROL TEST IS BETWEEN 70 AND 90, LESS THAN THAT IS DAMAGING AND MORE THAN THAT IS DAMAGING, ASWELL PROPORTIONS!!! FOR EACH 10000 IDs OF D3 YOU WOULD BE NEEDING 100 MICRO GRAMS OF K2, THAT ITS JOB IS THE TRANSFER OF CALCIUM WHICH IS BROUGHT BY THE D3 INTO THE BLOOD, OUT TO THE CELLS, UNLESS THEY`D REMAIN AND GET WASTED ASWELL`D CAUSE CALCIFICATION OF THE ARTERIES, AND THUS PROPORTIONS, WITH MEASUREMENT (LAB FEED BACK),
Thank you SO MUCH for this video! ^_^ Personally, I have Ehlers-Danlos Syndrome (EDS) and people with EDS are advised to take massive doses of vitamin C 4g on an ordinary day and 6g if we have a viral/bacterial infection or if we’re experiencing a flare-up of our EDS symptoms. But that’s because of the role vitamin C plays in collagen synthesis, since collagen-related mutations (either in the collagen genes or in other genes that produce, for example, enzymes involved in the protein folding) are believed to be at the heart of Ehlers-Danlos Syndrome. There’s a lot more going on with EDS than just collagen, but that’s the part we mostly understand, at the moment.
We also tend to suck at synthesizing vitamin D, so most of us have to supplement that, too.
But it drives me insane to hear normal, healthy people with balanced diets raving about all the supplements they take “for their health”. And don’t even get me started on the whole “vitamin C prevents/cures colds” bullshit…! I’d really love to see you guys do a video on that, too the vitamin C vs colds myth. Please? =] xox
stop trying to legislate vitamins like you know something that nobody else does i dont see you telling people to stop buying food do to all the poisons and chemicals found in it
I love how no scientific testing has showed that multivitamins do anything. If they did a test on vegetables to see the health benefits it would be quite clear. Also the methods they use to make vitamin tablets may make them not adsorb into your body at all and go right through you. Think people take them because of the placebo effect. Hey people who get medicine degrees need to find a job somewhere:p
You should take in mind that most of the first world urban population does not have a healthy, balanced diet and thus needs such supplements. Said urban population is the main target of the stores that sell them. So I don’t think that the first of your statements is true.
As naive as the B lymphocyte before it recognizes the antigen ����������
It pretty much doesn’t make any sense. I bet 90% of the people
especially in the 1st worldare not taking the essential minerals and vitamins from their daily meals. So this means you definetly need supplements. Now, if you are doing some blue collar job or you are doing sports regularly than it is crital to use some sort of multivitamin.If I take the recomended daily dosage than how in the world am I supposed to be sick from it, since authorities (cough cough influenced by the pharmaceutical companes) are usually picking on nutrition supplement companies?
Last but not least, some might forget that the fruits and vegetables which are grown in glass houses doesn’t contain shit. What is best? Plant your own vegetables and fruits in your garden.
I can’t take this man seriously with those earrings, goatee, and yellow patch of hair on the left side of his head.
There is no chance of you hitting 100% of the RDA through a balanced diet. If you had a degree in this you would know how impossible it is. Vitamin D is an easy example.
Er….this video sounds like it was made in the 50’s (about when the vitamin dosage standards were created). I expected something better from you guys.
When I was pregnant, I took my vitamin every day. Now, once a week.
Didn’t seem to cover much in this video. No benefits were explained and you spoke as if everyone has a balanced diet. and I know for a fact there are micronutrients that are not consumed every day. So why not take a multi to ensure you get everything you need?
Bravo!
Vitamins are a necessary myth for fools to feel better.
Well this is about the right time to be skeptical of those recommended daily dosages, since the entire video is based on that.
Warning: too many vitamins will lead to annoying hand gestures.
Sorry, but this one missed the mark. The title and opening remarks talked about multivitamins-but then went on to say that megadoses can be dangerous. Megadoses of nearly everything can be dangerous, even water and oxygen. It’s true that large amounts of water soluble vitamins can lead to needlessly expensive pee, and that the fat soluble vitamins can potentially be toxic, but by multivitamins most people mean the one per day variety, and I challenge to you to cite a case where anyone who took these as directed suffered ill effects. It should also be noted that RDA’s do not usually specify the age, sex, or mass of the taker. And it should also be pointed out that not everyone is eating anything near an ideal diet. Those simple and really inexpensive daily pills are the cheapest health insurance available. Of course they won’t work forever. Neither will anything else. In the meantime, don’t leave your house, don’t drink the water, and don’t breathe the air.
There are so many supplements in the market which one to choose?
Do you agree that not all supplements are created equal?
Since 2013 I trust only one brand to take care of my nutritionals need.

Hope this information helps
What about if you’re NOT eating healthy!? Wtheck?? Lol Were we just supposed to not at all notice that huge hole? hahaha omg that made me laugh. If you’re deficient, that’s why they pump them up, with the idea you just pee out the rest as your body is pretty good at filtering out things it doesn’t need. And most people are deficient in Vit D, which over the past 7-10 yrs has been shown as being more and more important. Most compounds do Not compound in the bodyheh heh. 😉 Can be harmful with say, Iron as an easy example, but conversely, a deficiency in iron can be a serious issue. This video is a fluff piece with not a lot of info.
My coach said to us that we should take multivitamins. He said that thats the basic stuff.

Only good reason for supliment is medical condition or if you’re vegeterian for B12. That’s it.
Vitamins: “Too much of anything is bad for you”..
Not if you live in venezuela… like me:(
This is why when I take multivitamins, I don’t take the whole reccommended dosage/serving on the back. I don’t need all 300% of the vitamin C that comes in two gummies. I’d say I have a relatively balanced and nutritious diet, but things like vitamin D are hard to get normally because of where I live. I have noticed though that over the months I’ve been taking multivitamins, I do tend to feel better as opposed to when I run out and don’t take them for a few days, though this be something akin to the placebo effect.
“assuming you eat a balanced diet” i’m going to stop you right there-what if i’m not? isn’t that a situation where multivitamins are helpful?
I’ve been taking an Omega 3 supplement every morning for months. Am I wasting my money/damaging my health?
Hello medicosis
What if I have a patient who is on warfarin then he had a bleeding attack and used one Vit.k injection to stop the bleeding but this would affect his pt and ppt values. So what is the perfect time for reassaying his tests
I like your videos so much sir, it’s so helpful. I’m medical laboratory science student. The question you asked, the answer is factor V, because this factor is Vit K independent and produced by the liver. Thank you very much.
I’m not a med student but a lot of things in these videos are useful for a layman too
I am ALWAYS spurred on to discover the answers to your questions, though I often am unable to find them, it does lead me to learn more fascinating info along the way. Love the eye of Horus. lol. Thank you once again.
