With a heavy heart, we have decided to close our Hamilton Blvd location, with our final day of business being December 18, 2025, and combine both stores into one single Sioux City location at Sunnybrook / Morningside.

As customer shopping habits have changed over the years—especially with more people choosing to shop online—it no longer makes sense to operate two retail locations in Sioux City. By focusing on one store, we can serve you better with stronger inventory, improved availability, and the best customer service possible at our Sunnybrook location.

For the 20 years we were open on Hamilton Blvd, it was truly a pleasure serving this community. We are incredibly grateful for every customer, every conversation, and every year of support.

We look forward to continuing to serve you at our Sunnybrook / Morningside location, online at www.mysciencenutrition.com, and beyond.

Thank you for being part of the Science Nutrition family.
