It also says Vitamin D plays an important role in regulating immune system function. The packets are described as having a delicious and refreshing natural orange flavor and are sweetened with natural sweeteners. The product is labeled Gluten-Free, Vegetarian, and Caffeine-Free. The listing notes it is Medicare Advantage OTC eligible, with the caveat that OTC benefits and eligible products vary by plan and that buyers should check their plan for specific details. The page places the item under the Emergen-C brand store and shows a related 60 count option at a higher price, along with other Emergen-C and Walmart listings in the same category, such as gummies, crystals, chewables, and other flavors. The seller shown is Walmart.com, which lists the item as sold and shipped by Walmart, with options for pickup and delivery and for a one-time purchase or a subscription. The listing also mentions a video overview and customer reviews.
