The British government recommends everyone take vitamin D during winter, and to consider it all year round if you have dark skin.
Running the numbers, the difference in cost of taking a multivitamin all year versus taking just vitamin D works out around the price of a pint of beer.
So I might as well take the multivitamin. How do I know I'm getting enough molybdenum (whatever that does)?
- Hendrikto 2y ago> So I might as well take the multivitamin It is possible to overdose on vitamins, and you can get adverse effects. It‘s not really a good idea to indiscriminately ”just take everything every day“.
- razakel 2y agoThat's true, but you have to do some really silly things to get to that point. You're not going to overdose on a multivitamin from the supermarket.
- The_Colonel 2y agoDepends on the vitamin. It's difficult to overdose on Vitamin C for example. Vitamin D should be dosed with caution, but taking e. g. 1000 IU a day should be safe even if you get it from other sources.

- beiburg 2y agoActually, it is possible to overdose on vitamin D, though it’s relatively rare. Vitamin D toxicity, also known as hypervitaminosis D, occurs when there is an excessive amount of vitamin D in the body. This can happen through very high doses of supplements over an extended period or by accidental ingestion of high-dose vitamin D supplements.
- ekianjo 2y agoeverything including water can be toxic at high doses. when I say its not really a thing, it means that it is indeed very uncommon compared to the amount of people who take supplements.
- OJFord 2y agoOk, so paracetamol (aka Tylenol, acetaminophen) overdose is also 'not really a thing', because despite it being absolutely possible to trash your liver and die, the number of people who do that (including as a suicide attempt, as does happen) is miniscule compared to the approximately everybody who takes it.
- ekianjo 2y agoThe safety margin for Vitamin D is on a totally different scale vs the safety margin of Paracetamol (which is very thin, it's easy to overdose on it). bad analogies are bad.
- Beretta_Vexee 2y agoUnfortunately, this is quite common among parents who want to make their own infant formula. They don't know how to dose milligrams and give ten or a hundred times the prescribed dose to infants. https://www.anses.fr/en/content/vitamin-d-opt-medicines-avoid-overdosing-infants https://www.anses.fr/en/content/vitamin-d-opt-medicines-avoi...
- staticman2 2y agoThe blood test for vitamin D my doctor showed me includes a safe range.
- teamonkey 2y agoThe trouble is that supermarket multivitamins don’t contain the amount of Vit D required to make up for lack of sunlight in the UK; you need a high-strength D tablet in addition to the D in your multivitamin (The UK govt recommends a 100IU supplement of Vit D per day and this is what most multivitamins provide, but current understanding is that an adult needs 1000-2000IU total per day, which is hard to achieve from sunlight and food in the UK)
- alias_neo 2y agoQuite right. I recently started taking multivitamins, and was told by the doctor I need to take 800IU per-day (based on my blood levels) of Vitamin D (I have "Olive" skin), the multivitamin provides only half of that (400IU/10uG). You shouldn't double up on the multivitamin or you'll be overdosing on other vitamins it contains, so an additional Vit D is required.
- OJFord 2y ago> The UK govt recommends a 100IU supplement [...] current understanding is that an adult needs 1000-2000IU The NHS recommends you consider taking 400IU, and not more than 4,000IU: https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/ https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-... (That page also says 400IU is what adults need, do you have a source for your 'current understanding' by any chance?
