How to properly store vitamins and supplements so they don't lose their properties?

Proper storage of vitamins and dietary supplements plays a key role in maintaining their chemical stability and effectiveness. Many people neglect basic rules by leaving bottles on the kitchen table or in the bathroom, which leads to the rapid destruction of active components under the influence of heat, light, and moisture.

Most vitamin complexes and supplements require storage in a dry, dark, and cool place at a temperature not exceeding twenty-five degrees Celsius. The bathroom is the worst place for a medicine cabinet due to constant fluctuations in humidity and temperature, which contribute to the destruction of capsules and the multiplication of bacteria. The kitchen near the stove also creates unfavorable conditions due to heat from cooking.

Special attention should be paid to probiotics, fish oil, and liquid forms of vitamins. Probiotics contain live beneficial bacteria that can die at room temperature, so manufacturers recommend keeping many of them exclusively on the refrigerator shelf. Liquid forms of oils and fat-soluble vitamins oxidize quickly in the light, which is why they are produced in dark, opaque bottles that should not be left under direct sunlight.
