Multi-vitamins/body weight/dosage question...

[7795]

One a day multi-vitamins all claim to given you up to 100% of your bodies daily needs (of course it is best to have a balanced and healthy diet and getting your vitamins from fruit/veg/cereals etc, etc...).

Will a 20st person get the same benefit as a 10st person if they take one a day as recommended???

Is there an optimum/average weight that all the drugs companies work to so people too light will not absorb all the vitamins and people too heavy will need to increase the dosage??

Anyone??

Take as many as you want, they don't work.

Yet to see the headline "man overdoes on vitamin tablets".

Vitamin tablets are expressly designed not to have an effect so they cant accidentally fall foul of MHRA/FDA rules governing medication. They're the pharmaceutical industries second biggest money maker after erectile dysfunction pills as they cost nothing to make and marketing has convinced people they "need" them daily.

I was always lead to believe that if you put too many vitamins into your system you just piss them out so therefore you can't overdose.

Not that I really take them anymore, or any supplement. Apart from maybe Berocca but I like the taste of that.

Is it a “well known fact” that they don’t do anything or a fact? It’s a genuine question, I’m not trying to be obstinate.

I understand they are a supplement but am curious if what you say and taken verbatim is true, why are they still on sale?

Some good info there.

I take some, but then I don't have a very varied diet, so it's an easy way to get them in.

Loads of things are on sale that have been proven time and time again to be utterly useless - homeopathy, reflexology, acupuncture etc. All the peer reviewed science says that they do the square route of fk all.

The majority of the studies I have seen suggest that taking vitamin supplements is a complete waste of time - I have an interest in this as both my wife and mother believe in codste that I am keen to debunk.

I'm not sure what the dosage calculation is for supplements, but most over the counter medicines are calculated very conservatively.

e.g. ibuprofen can be dosed at 40mg/kg in a healthy adult, therefore an 80kg man can take 3.2g of ibuprofen a day (in 4 doses). The patient information leaflet will say 1.2g per day as a maximum dose.

I would think that most supplement RDAs are calculated for a ~ 60kg adult. Adjust accordingly.


p.s. some drug doses are calculated on surface area
