The reality is that we pee out the majority of multivitamin content, but it does help a bit. That being said, those prices you listed are ridiculous. Just get a generic multivitamin from Boots or whatever, and it'll give you the same vitamin benefits as the fancy company.
This is true for those who do get enough of their vitamins from food, but if one is consistently only getting 50% and their multi has the remaining 50% (like a good multi should, no multi needs to have 100% of everything) you will not pee it out. Additionally, Vitamins A, D, E, and K will not get peed out as they will be stored in ones fat stores. Most people here don't really eat a lot, so the assumption of a healthy, vitamin rich diet cannot be applied.
Sorry if this has been asked/is a stupid question.
basically I have a list of vitamins I believe I need - vit d, c, b, collagen, omegas, calcium. I eat approx 1200 cals a day and I know I’m not getting enough of these in my diet. I found a subscription website that will send me all these vitamins monthly for £50. But I don’t know if it’s worth it? Is that a standard price for these vitamins? I’ve looked at other websites and it’s roughly the same price.
but also when we take these supplements, do they actually work or do we just end up with expensive pee?
again, sorry if this is a stupid question, I’m just trying to get my head around it all before I go and splurge on supplements.
@ OP, check carefully on your calcium. Most studies that recommend 1,200mg are flawed and we really only need 500 to 700mg depending on certain factors like sex, weight, age, and activity level, and too much can be harmful. You probably get enough if you drink any sort of milk (fortified if plant). Focus on Vitamin D instead getting 800 IU to 1,000 IU per day.
And to answer your main question. Yes, supplements work as long as you actually are experiencing a vitamin/mineral insufficiency of deficiency. There are also lots of off label usages, however this isn't the question you had so I will not be going into much detail about that, but I feel it is important to explain. Basically, unless you are trying to treat a condition that uses a vitamin/mineral in a separate way than the general use of the vitamin/mineral in the body. For example, Vitamin B3 (Niacin) can be effective in correcting abnormal levels of blood fats, however this requires at least 500 mg or more to correct. In contrast, we only need 14mg with an upper limit of 35mg per day when not using it to correct blood fats. The reason we are able to use niacin to correct these issues is because the risk/benefit analysis is in favor of too high niacin levels vs too high blood fat levels. You usually only need 100% of your vitamins/minerals and extreme excess could be harmful and sometimes fatal.
Basically, taking supplements should only be used for supplementation and when taking them, we need to use the minimum dose necessary to fill our nutrient gaps.
And that is insanely overpriced. I got a 3 month supply of 1000 IU vitamin D for 4£ and that's a pretty average amount of money to meet your RDA/AI, however some might be up to 9£ or down to 2£.
