Thanks to its critical role in immunity, vitamin C has gotten a lot of attention over the past few years.* However, many don’t realize that vitamin C is a potent antioxidant involved in a myriad of physiological functions that help your body run properly every single day–not just when you’re feeling under the weather.*

Vitamin C is an essential nutrient, which means the human body can’t make it on its own (and thus, must consume it). Additionally, it’s a water-soluble vitamin, which means any C your body doesn’t absorb each day will be excreted through your urine.

For these reasons, it’s so important to make sure we’re consuming enough vitamin C daily from our diet and supplements to support our skin, joint, heart, brain, and cellular health.* (Sadly, approximately half of U.S. adults are failing to do just that.)

In addition to eating enough vitamin-C-rich foods, high-quality supplementation is a fantastic way to ensure we’re getting an effective dose of C to support its array of benefits and whole-body health.* Trying to find the best vitamin C supplement can be overwhelming, though. (That’s where we come in.)

If you’re on a mission to up your vitamin C intake, this comprehensive guide will help you find the best vitamin C supplement for you and your health needs.

What to look for in a quality vitamin C supplement.

We scoured the market for the best vitamin C supplements available and, using a few key criteria–including form, source, dose, and quality–narrowed it down to the carefully curated list of supplements you see today.

From vitamin C-lipid-citrus bioflavonoid trios and chewable tablets to gummies and liposomal powders and liquids–vitamin C supplements can take many different forms. The good news is that the delivery format doesn’t matter too much (although, we recommend you reserve gummies for kids or adults that don’t care to swallow other forms of vitamin C). Rather, it’s what’s inside the vitamin C supplement that really counts.

Whether you’re trying to understand our selections better or doing research to find a vitamin C supplement on your own, here are the most important factors to evaluate, as determined and vetted by our vice president of scientific affairs, Ashley Jordan Ferira, Ph.D., RDN:

Form and source of vitamin C

When selecting a high-quality vitamin C supplement, one of the most important factors is the form of vitamin C and how well it absorbs. Here are a few common forms and sources of vitamin C you will see in our list of selections and on other ingredient labels:

Vitamin C-lipid-citrus bioflavonoid trio. Especially designed for high-potency doses, the fatty acids (aka lipids) in this specialized trio help escort vitamin C through the body and aid cellular absorption, while citrus bioflavonoids help protect the C (but more on that in a moment).*

Ascorbic acid. This is a widely used and robust option for vitamin C, as it’s well absorbed at lower doses and your body will excrete what it can’t use via urine.

Liposomal vitamin C. Found in both powder and liquid form, the liposomes (aka phospholipids) in this form encapsulate vitamin C to help transport it through the GI tract and into cells, so it can be absorbed.*

Fruit. In some supplements, vitamin C is sourced from whole fruits, such as berries (acerola, amla, and rose hips being particularly famous ones). PSA: These whole-food sourced vitamin C options will provide lower amounts of vitamin C (i.e., not your 1,000-milligram doses) because these fruits do not contain 100% vitamin C, so achieving very high doses would be costly for both the manufacturer and consumer.

Citrus bioflavonoids. Although citrus bioflavonoids are a unique set of phytonutrients and not a form of vitamin C, you might see them in specialized vitamin C supplements because they are wonderful plant-origin accessory bioactives that complement vitamin C and buffer it from oxidation.*


The amount of vitamin C in your supplement is just as important as where it’s coming from. The recommended dietary allowance (RDA) for vitamin C is 75 milligrams in female adults and 90 milligrams in male adults. That’s a daily baseline level.

Of course, dosing of vitamin C in supplements depends on what the particular supplement is designed to achieve. “When considering a multi-ingredient product (e.g., an immune complex or multivitamin), look for 90 milligrams of vitamin C or more to cover both male and female needs,” explains Ferira. “With standalone, high-potency vitamin C supplements for adults, look for higher doses (i.e., anything from 250 milligrams to 1,000 milligrams).”

High-quality, clean ingredients

The supplement brands we recommend have a reputation for stellar quality. Whether they achieve this status through vigorous manufacturing and quality testing or additional, independent third-party testing, you can rest assured that each selection on this list is of the highest caliber.

Often, this commitment to quality is also reflected in a supplement’s ingredient list. We look for active ingredients with clinical science backing and products that are free from artificial colors, flavors, sweeteners, dyes–and, whenever possible, free from gluten, soy, dairy, and GMOs as well. In terms of excipients (i.e., the inactive, additional ingredients included in a supplement formula), the shorter and cleaner the list, the better.

The benefits of taking a vitamin C supplement.

Vitamin C is the body’s primary water-soluble antioxidant–which means it’s a true nutrient leader for its vast (and vital) antioxidant and anti-inflammatory actions across organ systems throughout the body.* In addition to being essential for immune and skin health, vitamin C directly supports our joints, cells, brains, and hearts (talk about true head-to-toe coverage).*

Here are a few of vitamin C’s particularly noteworthy roles worth calling out:*

With regards to both innate and adaptive immune response, it promotes the function and resilience of a healthy immune system.

It enhances the bioavailability of iron by directly aiding in iron absorption.

It promotes heart health by supporting vascular function and helping maintain a healthy blood pressure.

When it comes to brain health, it’s involved in neurotransmitter synthesis and promotes cognitive function.

It supports both the production and preservation of collagen, our body’s most prevalent protein (think: skin, joints, gut, blood vessels, and more).

Best Vitamin C Supplements

Best overall: mindbodygreen vitamin C potency+

vitamin C potency+ delivers a powerful 1,000-milligram vitamin C dose (equivalent to 15 oranges!) of our body’s primary antioxidant in a gentle and optimized form. Backed by clinical research, this scientifically advanced vitamin C-lipid-citrus bioflavonoid trio demonstrates superior ability to raise vitamin C levels in our body, achieve retention in cells, and deliver antioxidant (free-radical-scavenging) plus anti-inflammatory (CRP-reduction) actions compared to other forms of vitamin C. For a powerful daily dose of bioavailable vegan C and a broad-spectrum array of citrus bioflavonoids from 100% citrus fruits, this optimized option (that’s also free of GMOs, gluten, soy, dairy, and major food allergens) is a no-brainer.*+

Best liposomal vitamin C: Pure Encapsulations Liposomal Vitamin C liquid

If you’ve done any research on unique delivery forms, you’ve likely already heard of liposomal vitamin C. This liquid format is the best design to achieve true vitamin-containing liposomes, thanks to the sheering force of shaking the liquid. This helps the active (vitamin C, of course) mix with the sunflower-derived phospholipids (so don’t forget to shake). The addition of fat helps aid vitamin C’s absorption. We love that this formula is GMO-free and vegan, but do note: It requires refrigeration and some amount of endurance (instruction: hold 1 teaspoonful in mouth for 30 seconds).*

Best timed-release vitamin C: Solaray Timed Release Super Bio Vitamin C

If you haven’t noticed yet, absorption is top priority when it comes to vitamin C supplementation (or any supplement, for that matter). Timing is the absorption angle in Solaray’s product, with a two-step timed release design aimed to deliver the first half of its 1,000-milligram dose of vitamin C immediately, then release its second half gradually as the day progresses. With citrus pectin plus bioflavonoids from lemons, the formula provides some complementary phytonutrients to the MVP: vitamin C.*

Best Ester-C: Solgar Ester-C Plus 500 mg Vitamin C Vegetable Capsules

Ester-C is a non-acidic form of vitamin C designed to be easier on the digestive system. It features calcium ascorbate–a mineral, “buffered” form of vitamin C and type of vitamin C metabolite that aids in white blood cell absorption and retention of vitamin C, according to Solgar. This mid-range formula delivers 500 milligrams of vitamin C, plus a modest amount of citrus bioflavonoids to provide some “buddy” phytochemicals and antioxidant power.*

Best vitamin C with food + herb blend: MegaFood Ultra C-400 mg

When it comes to antioxidants, citrus fruits and berries shouldn’t get all the credit. In addition to a mid-range 400-milligram dose of ascorbic acid paired with some organic orange, this MegaFood vitamin C supplement offers a compact amount of ingredients derived from fruits, vegetables, grains, and herbs. (You’ll even find some brewer’s yeast in the mix.) While some of the key players are well-known for providing antioxidants (e.g., blueberry, carrot, orange, and cranberry) others (e.g., beetroot, broccoli, and parsley) may surprise you!*

The takeaway.

Vitamin C is an incredible essential nutrient that performs countless antioxidant and anti-inflammatory actions within the body to support everything from cardiovascular function to cellular resilience and immune response.* Although vitamin C is needed daily to support these physiological functions, a large chunk of the U.S. adult population has insufficient vitamin C levels (42%, to be exact) per their bloodwork. A high-quality supplement can complement your diet to help bridge that nutrient gap, ensure sufficient vitamin C status, and allow your body to leverage this readily available C however it needs.*

When considering adding a new supplement (vitamin C or otherwise) to your routine, it’s always a good idea to discuss your options with a health care provider. Whether you’re interested in one of the vitamin C supplements we’ve featured here or are using the criteria above to advance your hunt for a different supplement, we hope this guide helps you find the perfect vitamin C product to address your health needs.
