Tag: Refrigerate vitamin c

Studies show that vitamin C is highly sensitive to oxidation and can be easily destroyed by heat and exposure to light. Knowing what temperature should vitamin C be stored at is crucial for preserving its effectiveness, whether in serum, supplement, or food form.

According to a 2010 study published in the *Journal of Agricultural and Food Chemistry*, humidity has a greater impact on vitamin C stability than temperature. However, heat and light still cause degradation, leading many to wonder, "are you supposed to keep vitamin C in the fridge?" The answer depends on the product's formulation, but keeping it cool can often extend its lifespan and potency.
