Tag: Vitamin k stability

According to the University of Rochester Medical Center, vitamin K is generally stable at room temperature and does not need to be refrigerated. However, it is highly sensitive to light and moisture, which can degrade its potency. For most users, understanding these environmental factors is far more critical than deciding whether to refrigerate vitamin K.

Research indicates that Vitamin K1 is extremely sensitive to light, with one study showing up to 87% degradation in vegetable oil after just two days of fluorescent light exposure. Understanding what can destroy vitamin K is crucial for preserving its nutritional value, both through dietary choices and proper food handling.
