Over 97% of light is blocked by modern opaque milk containers, a design implemented specifically to protect a certain vitamin from rapid destruction. This packaging is a direct response to a fundamental vulnerability certain essential nutrients, particularly riboflavin, have when exposed to light.

According to the National Institutes of Health, ultraviolet and visible light can rapidly inactivate riboflavin, or vitamin B2, a key finding that explains why food manufacturers use specific packaging. This critical light-sensitive property is why you rarely see milk sold in clear glass bottles anymore, a prime example of which vitamin can be destroyed by strong light. Understanding how light degrades this essential nutrient is key to maintaining nutritional value.

Despite being a water-soluble vitamin, riboflavin (Vitamin B2) is considerably more stable under heat than it is when exposed to light. While some degradation can occur with cooking, studies show that typical kitchen temperatures cause minimal loss, with other factors like water and pH playing a more significant role.

Milk loses up to 59% of its riboflavin when exposed to fluorescent light for just ten hours, a prime example of this nutrient's fragility. This illustrates that riboflavin is easily destroyed by light, a chemical process that significantly affects the nutritional content of many common foods.

Did you know that the opaque plastic jugs used for milk are specifically designed to protect a certain nutrient from light? The primary nutrient destroyed by exposure to light, especially ultraviolet (UV) light, is riboflavin, also known as Vitamin B2.

Up to 30% of riboflavin can be destroyed in milk within just 30 minutes of sunlight exposure, highlighting the vitamin's extreme light sensitivity. This process, known as photodegradation, is a critical concern for preserving the nutritional quality of many food products and pharmaceutical preparations.

Studies reveal that vitamin C, a common skincare ingredient, is highly unstable. For this reason, vitamin C needs to be in a glass bottle, as the packaging shields against degradation, ensuring product effectiveness.

According to a study published in the journal *Food Science*, exposure to light can cause significant degradation of sensitive nutrients in food, especially riboflavin. This vital nutrient, also known as vitamin B2, is particularly vulnerable to the chemical process known as photodegradation. Understanding this light-sensitive property is essential for preserving the nutritional quality of both food and dietary supplements.

Scientific studies have confirmed that folate is indeed highly sensitive to UV radiation, leading to its degradation both in foods and within the human body. This photodegradation, or breakdown by light, can reduce the effectiveness of folate supplements and affect overall folate status. Understanding this process is crucial for protecting your folate intake.

Over 90% of vitamin C in our diet comes from fruits and vegetables, yet many skincare users worry about light exposure degrading their products. This fear has led to a common question: does red light destroy vitamin C? The answer is a clear no, and understanding why can revolutionize your skincare routine.
