They definitely can be. If you're currently taking 3+ separate vitamins and supplements, it might make sense to switch to a personalized vitamin subscription. It can be tough to stay stocked up on multiple vitamin/supplement products, and a personalized subscription will automatically stay on top of them for you. Plus, it's a way to cut down on shipping costs and packaging. A subscription also simplifies your daily routine — no more fussing with a pillbox or trying to store a bunch of bottles of vites. Lastly, some brands offer access to dietitians to chat about nutrition and supplements, which is a huge value-add if you're not currently working with a healthcare professional on your diet needs. OTOH, personalized vitamin subscriptions can get pricey, are sometimes hard to cancel, and don't always take your health history into consideration.
