National Multivitamin Day – September 20, 2025

National Multivitamin Day underscores the importance of nutritional supplements in promoting health and well-being. Recognizing that 75% of the U.S. population doesn’t meet the standard healthy diet guidelines (according to Dietary Guidelines for Americans 2020-2025), National Multivitamin Day is dedicated to exploring how the right kind of multivitamins can fill dietary gaps, support immune function, and improve overall health. 

History of National Multivitamin Day

Established in 2024, National Multivitamin Day is held every third Saturday in September to remind us that pizza is not a food group. This holiday is dedicated to educating consumers and highlighting the essential role that multivitamins play in promoting health and wellbeing.

To bring this to life, GNC set out to launch National Multivitamin Day to serve as a platform to educate people on how to choose and use multivitamins effectively ensuring they complement a balanced diet for a healthier lifestyle. Think of your multivitamin as the foundation of your house. Just as a strong foundation supports a long-lasting home, a high-quality multivitamin supports your health for years to come. However, only 1 in 4 multivitamin consumers in the U.S. have complete confidence that their multivitamin brand provides accurate nutrient information. That’s why it’s crucial to choose a trusted source, like GNC, which offers multivitamins proven in clinical trials to better boost levels of key nutrients compared to basic multivitamins.

And while some vitamins and multivitamins are popular, many may have other impacts on overall health. For instance, gummy vitamins, which have seen a significant rise in popularity with a market growth of 70% in dollar sales over the past four years, often contain high amounts of sugar—many between 1 and 8 grams per serving—and may not provide the full daily value of essential nutrients. In contrast, capsules and tablets can contain a higher dosage of vitamins and minerals without added sugars.

Celebrate National Multivitamin Day by exploring the world of multivitamins and unlocking the potential of your health by learning how the right supplements can enhance your wellbeing. Whether you’re just starting out or looking to refine your nutritional intake, GNC invites you to connect with experts, access valuable resources, and understand the choices available that can have a positive impact on your health span.
