We Asked Registered Dietitians What Vitamin C Supplements They Recommend — Here Are Their 14 Top Picks

New Chapter Immune Defense Vitamin C+ gummies earned our top spot as the best gummy for their taste and nutrition. “Many gummy vitamins are high in added sugar and contain gelatin, rendering them unsuitable for vegans,” says Amy Brownstein, RDN, a plant-based dietitian in Oakland, California, and owner of Nutrition Digested. “New Chapter’s Immune Defense Vitamin C+ gummies use pectin (a vegan thickener made from plants) and have 40 percent less sugar than typical gummies, thanks to the organic blue agave fiber.”

These gummies contain 2 grams (g) of added sugar per serving, which some people may want to consider if following a low-carbohydrate or low-sugar diet. However, the inclusion of inulin, a prebiotic fiber derived from organic blue agave, supports gut health and helps offset the sugar content. Additionally, the brand is committed to sustainability and transparency by using third-party testing to ensure safety and quality. New Chapter Immune Defense Vitamin C+ gummies are a solid choice for those seeking an alternative to capsules.

For adults who don’t love taking pills (or just like the taste of vitamin C chewables), we love NaturesPlus Chewable Orange Juice Vitamin C Supplement. Each chewable provides 250 mg of vitamin C from ascorbic acid and only 1 g of added sugar, sourced from non-GMO cane sugar.

NaturesPlus is a trusted supplement company, and all of its products are manufactured in-house in facilities that adhere to current good manufacturing practices (CGMPs), ensuring manufacturing, packaging, and distribution processes meet the highest standards.

Many chewable supplements have a chalky or overly sweet taste, but this product strikes a pleasant balance with its minimal sugar content. As each serving has 1 g of added sugar, those following a stricter diet may want to choose an alternative. It also doesn’t contain any additional immune-supporting nutrients. However, NaturesPlus Chewable Orange Juice Vitamin C Supplement delivers a simple but tasty blend of quality and convenience that ticks all the right boxes.

Pure Encapsulations Buffered Ascorbic Acid Powder stands out for its high-quality formula that’s easy on digestion. “Pure Encapsulations Buffered Ascorbic Acid Powder is the most gut-friendly powdered vitamin C I’ve found — and I’ve tested a lot,” says Simpson. “It skips all the junk ingredients like added sugars, artificial sweeteners, and unnecessary fillers, which can sneak into even ‘healthy’ supplements.”

This powder features buffered ascorbic acid, a unique formulation combining calcium ascorbate, magnesium ascorbate, and potassium ascorbate to neutralize acidity, making it ideal for individuals with sensitive stomachs. “It delivers a buffered, pH-neutral dose of vitamin C that’s easy on your stomach and highly absorbable — perfect if you’ve ever felt queasy, bloated, or acidic after taking standard ascorbic acid,” says Simpson.

One scoop provides 1,220 mg of vitamin C that tastes good and easily mixes into water. While this high potency ensures you’re getting maximum support, it’s important to note that this amount of vitamin C may not be suitable for everyone without consulting a healthcare provider.

Overall, Pure Encapsulations Buffered Ascorbic Acid Powder delivers a gut-friendly formula for anyone looking for a potent and gentle way to supplement their vitamin C intake.

Although the capsules are somewhat larger due to their high dose of vitamin C, most reviews indicate they’re easy to swallow. Keep in mind that, at 1,000 mg of vitamin C per capsule, the dose may be higher than some people need. That said, most online reviews were positive, indicating that this vitamin C supplement was gentle on the stomach and didn’t cause nausea, unlike some vitamin C supplements.

If you prefer to take your vitamins in a liquid form, Rho Nutrition Liposomal Vitamin C is a great choice. It uses a liposomal delivery for better absorption, making it an effective and easy way to get your daily dose of this essential nutrient. “From a sports performance lens, Rho Nutrition Liposomal Vitamin C is one of the most functional and efficient ways to deliver this key antioxidant,” says Kirbie Daily, RD, assistant director of sports nutrition for the University of Memphis. “Its liquid form ensures both fast and effective absorption.”

Daily also likes that this product has a simple ingredient list with no added sugar, and the liposomal form makes it gentle on the stomach for those with GI sensitivities. She suggests it can be mixed into water, smoothies, oatmeal, or chia seed pudding.

At 1,000 mg per serving, this is a high-dose product, but you can always take less as needed. “The flexible dosing is another major win, allowing tailored intake based on training load, illness risk, or travel exposure,” Daily says. “GMP and third-party certifications also ensure that this liquid supplement truly contains what is on the ingredient list, making it a trustworthy choice for all.”

Keep in mind that liquid products aren’t always as convenient and may need to be stored in the fridge. Whether you’re an athlete focused on post-training recovery, a frequent traveler seeking immune support, or simply someone who values a high-quality supplement, this product is a reliable choice.

Each serving provides a concentrated dose of antioxidant-rich vitamin C, supporting immune health, collagen synthesis, and overall wellness. “When higher doses are needed, it’s best to divide them throughout the day and take vitamin C with a small amount of fat or fiber to enhance absorption,” suggests Ballenthin.

Although this is a high-dose product, the powder form gives users flexibility to customize their intake based on their individual needs. Overall, Designs for Health Vitamin C powder is an excellent option for those needing higher doses of vitamin C.

Thorne Vitamin C is also ”easy to swallow and is gluten-, dairy-, and soy-free,” Huff points out. These features ensure that individuals with dietary restrictions or sensitivities can enjoy its benefits worry-free. This supplement is third party–tested and NSF (National Science Foundation) Certified for Sport.

While the high dose is generally safe, Huff explains that vitamin C is water-soluble, so any excess will be excreted in the urine. Overall, Thorne Vitamin C With Flavonoids impresses us with its clean, effective, and nutrient-rich formulation.

Liposomal supplements can be more expensive than nonliposomal forms, which might not work for everyone’s budget. Additionally, their fat-based delivery method may not suit everyone’s preferences or dietary restrictions. Despite these considerations, we think BodyBio is a worthwhile investment.

For an affordable yet effective vitamin C supplement, Kirkland Signature C is our top choice. Alexandria Hardy, RDN, based in Lancaster, Pennsylvania, highlights this product’s value, noting that it’s approved by ConsumerLab.com for its exceptional cost-effectiveness and quality. ConsumerLab.com is a third-party testing organization that independently evaluates supplements for quality, purity, and label accuracy, adding a layer of confidence for consumers. Plus, at around $0.04 per serving, its unbeatable price makes it affordable for a wide range of budgets.

This product contains 1,000 mg of a citrus bioflavonoid complex, which offers added anti-inflammatory and immune-supportive benefits. It’s also verified by United States Pharmacopeia (USP), which means it has met rigorous testing standards set for quality, purity, and potency, so what’s listed on the label matches what’s inside the bottle.

That said, while the simplicity and value of Kirkland’s vitamin C are major strengths, the tablets are on the larger side. For individuals who struggle with swallowing pills, this could be a potential drawback (although you can break the tablets in half). Additionally, this is a high-dose supplement, so checking with a healthcare provider is always recommended. But for just $0.04 per serving, this product delivers significant value that’s hard to beat.

While we couldn’t find many downsides to this vegan-friendly vitamin C supplement, a few reviewers reported that the capsules smelled bad. Additionally, the high dose of 1,000 mg may be too high for some people. Still, since a dose is two capsules, you could easily reduce the dose to 500 mg by taking just one capsule.

There are mixed reviews on taste and mixability, with some people noting it clumps when mixed with water and tastes sour. That said, many other reviews indicated that it had good flavor, so this may come down to personal preference. If you don’t like the flavor, it could be easily masked by mixing it with juice or blending it into a smoothie.

“Each capsule provides 500 mg of liposomal vitamin C,” says VenHuizen. While some may find the 500 mg dosage per capsule insufficient for individuals with elevated vitamin C needs, the advanced liposomal delivery system supports effective absorption to maximize its effectiveness. This product is also simple, with a single focus on delivering high-quality vitamin C, which may lack appeal if you want a supplement with added skin-supportive nutrients like hyaluronic acid or zinc. However, if you value simplicity, Now Liposomal Vitamin C is a top choice. And as a bonus, it’s budget-friendly, priced at around $0.15 per capsule.

For travelers seeking immune support on the go, Beekeeper’s Naturals Propolis + Vitamin C is the ideal choice because it comes in individual packets. This supplement combines 1,000 mg of vitamin C with 100 mg of propolis extract per packet to provide dual benefits: enhanced immune defense and antioxidant protection. “As a sports dietitian, I’m always weighing efficacy and ease of use when it comes to supplementation, and this product checks both boxes,” says Daily, highlighting the convenient, single-serve packets.

This product also caters to active lifestyles. “Athletes often juggle tight schedules, constant travel, and challenges to their immune system due to heavy training loads. Liposomal vitamin C ensures enhanced absorption, which is particularly beneficial under physical stress when nutrient demands and GI permeability may be altered,” says Daily.

While its higher cost per serving may deter budget-conscious buyers, Daily emphasizes that the improved bioavailability and immune-boosting formula make it a worthwhile investment. Its texture is similar to syrup, and it tastes like honey. That said, it’s also very sweet and may take some adjustment, but this minor drawback is easily outweighed by its portability and effectiveness. Whether you’re a frequent flyer, athlete, or looking for an effective immune boost during travel, Beekeeper’s Naturals Propolis + Vitamin C is an excellent choice.

Our top pick for kids is Renzo’s Invincible Vitamin C, thanks to its combination of quality ingredients and child-friendly design. It’s sugar-free, free of common allergens, and comes in an easy-to-take tablet that melts on the tongue. Manufactured in an NSF-certified facility and third party–tested, this product guarantees high safety and quality standards, ensuring each tablet contains exactly what it promises without contaminants.
