Before we dive into the details, we’d be remiss if we didn’t remind you that supplements are meant tosupplement a balanced, variety-filled diet, not replace it. Ideally, you want to choose supplements that have been independently verified so you know that what the label says is what you’re actually getting in the product. And because it is possible to overconsume certain nutrients, we recommend you discuss supplementing with your health care practitioner or a registered dietitian first. Without further ado, here are our top supplement picks on sale at Costco right now. But you’ll want to hurry—these deals are only good through Sept. 22, 2024.
EatingWell’s Supplement Philosophy & Methodology
Kirkland Signature Vitamin D3
$2.50 off a bottle of 600, 50 mcg softgels
We’re coming into winter, a time when many in northern latitudesfall short in vitamin D. This is because our bodies make vitamin D when enough of our skin is exposed to sunlight for a sufficient amount of time. But since most of us in northern regions are bundled up all winter and have shorter days with less intense rays, our bodies don’t get enough exposure to sunshine. And if you live in a warmer climate, things like air pollution may reduce the number of necessary UVB rays making it through your skin to make vitamin D. Unfortunately, fewfoods naturally contain vitamin D—fatty fish, mushrooms and egg yolks do, as well as fortified dairy products. But it’s important to get enough vitamin D since it’s essential for a healthy immune system and strong bones. Enter, Kirkland Signature Vitamin D3. These softgels go down easy and they’re independently verified, receiving the USP mark, so you know the quality is there. These softgels also contain no yeast, starch or gluten, and are free of artificial colors and flavors.
Kirkland Signature Vitamin C
$3 off a bottle of 500, 1000 mg tablets
Known for its ability to support the immune system—which is especially important as we come into cold and flu season—it might surprise you that vitamin C is also necessary for ahealthy gut, skin and brain. When we think ofvitamin C, many think of citrus fruit, like oranges and grapefruit—and they are important contributors. But there areother vitamin C rock stars, including broccoli, kiwi, bell peppers, guava, pineapple and papaya. If you find it hard to eat enough of these foods, this Kirkland Signature Vitamin C may help supplement what you’re missing. These tablets are gluten-, yeast- and soy-free, have no artificial flavors, colors or preservatives, and are USP verified.
Nature Made Prenatal Folic Acid + DHA
$5 off a bottle of 150 softgels
Nature’s Bounty Odorless Fish Oil
$5 off a bottle of 130, 1400 mg coated softgels
Most of us don’t eat enough seafood, including the recommended two servings of fatty fish per week.Regularly eating fatty fishcan help provide essential omega-3 fatty acids, which have been shown to reduce inflammation and heart disease, and support a healthy brain. But it can be difficult to get enough seafood for several reasons. Maybe you don’t care for it, are allergic to it or feel it’s out of your budget. No matter what the reason, it’s important to bridge the nutritional gap of the omega-3s you might be missing. These Nature’s Bounty Odorless Fish Oil coated softgels may help you do just that. If you’ve ever taken a fish oil supplement that wasn’t odorless, you know the consequential fish burps that come with them. Thankfully, these softgels are coated, making them odorless, and shouldn’t give you that fishy aftertaste or burps. They’re also USP verified. It’s important to note that they do contain oil from actual fish, so if you follow a vegan or vegetarian eating pattern or are allergic to fish, including anchovies, herring, mackerel and sardines, then these softgels are not for you. In these cases, you would want to get youromega-3s from plant sourceslike nuts and seeds.
