Tag: Vitamin d potency

According to a study published in *Wiley Online Library*, vitamin D3 retention in fortified oil stored at cooler temperatures (4°C) showed the highest stability, with half-lives ranging from 407 to 577 days. This raises the question of whether it is okay to store vitamin D in the fridge to extend its potency and shelf life, or if there are other factors to consider.

Most manufacturers estimate that vitamins can last up to two years from the date of manufacture, but this can vary depending on the vitamin's form and storage conditions. A bottle of vitamin D, specifically, has a distinct shelf life that is largely determined by its formulation and handling after purchase.

Globally, it's estimated that 1 billion people have low vitamin D levels, highlighting the widespread nature of this issue. Determining which potency of vitamin D should I take is a common question, and the answer is highly individualized, depending on various factors.
