Do Vitamins Lose Their Effectiveness Throughout Time?
It is without much doubt that vitamins lose their strength and usefulness with the passing of time. Due to the fact that supplements are not regulated by any government agencies, the producers of these dietary additions are not bound to provide suggested use-by or expiry dates. However, some supplements have them anyhow, and thus we recommend these for reasons of wellbeing.
It seems that vitamins can endure and last quite a long period of time, as long as 5 years. Expiration dates are set when the products are tested in order to measure the deteriorating of the components over time. It is a scientific fact that the chemical composition of nutrients and vitamins alters with the passing of time and therefore, diminishes their strength. However, they do expire, as some of the ingredients can and do spoil.
Are Expired Vitamins Safe To Take?
Yes, vitamin supplements, thought they lose their usefulness or potency with the passing of time, are still safe to consume, although they might not be as efficient as the labels on the pillbox state. So, for instance, if it says on the bottle, for instance, 500 milligrams of vitamin C, there is no guarantee that after the expiration or end-by-date a pill will continue to provide exactly 500 milligrams – in fact, it might provide a bit less, or a lot more.
However, vitamins whose best-by-date has expired do not become toxic or contaminated. However, even though there is no health risks involved, taking these kinds of vitamins will still not offer the benefits intended in the first place. The expiration date (which is most likely conservative and aimed to endure full strength, usually about one year) only guarantees that the ingredients will be effective up to the date listed on the label. After this date, they will slowly but surely undergo the process of oxidation, and thus become less useful. On the other hand, if the storage is inadequate (if, for example, they are kept in a humid environment, like the bathroom or the kitchen) this process will be accelerated.
The best advice, therefore, is to throw out all and any expired bottles of nutrients or vitamins that have run out.
However, if you have bottles of vitamins with supplements which are a couple of years past their expiration date, they can still be taken, as they hold no danger to overall health and it is very likely that they will do some, if not the full promised, good.
Hot To Boost The Shelf Life Of The Supplements
An effective practice of storing supplements properly can make sure that the vitamins are effective and can be used during the total recommended shelf life. Thus, the place and the way they are stored can have a great impact on the potency or usefulness of vitamins and aid with the obtaining of the needed benefits of the nutrients.
What causes vitamins to lose their strength and potency and break down? Mostly – humidity and heat. Which means, unless otherwise indicated by the instructions given by the manufacturer, store the nutrients in cool and dry surroundings. And, unless the label advises otherwise, these nutrients should not be stored in the fridge, due to the fact that that would hasten their breakdown.
Therefore, to conclude, vitamins are best kept out of the impact of direct sun rays, as this is another factor that also reduces their overall potency. Also, keep them in their original packaging, as the manufacturers usually pack them up in airtight bottles in order to ensure optimal efficacy.
