This article cuts through the hundreds of vitamin C supplements on the market to bring you the five best choices for strong year-round immune health, enhanced collagen production, anti-aging defense, and more.

As we reviewed each vitamin C supplement, we considered five important criteria:

1. Avoid Synthetic Vitamin C: Unfortunately, the vast majority of vitamin C products use a synthetic form of vitamin C called “ascorbic acid” or “ascorbate.” Nearly all of this synthetic, man-made vitamin C is industrially manufactured in China from genetically modified (GMO) corn. This makes it incomplete, missing the natural cofactors real vitamin C contains that help it work. Not only that, but synthetic vitamin C is poorly absorbed, causes stomach upset, and can actually rob your body of critical nutrients like copper. For this and many other reasons, we strongly recommend taking only a natural vitamin C.

2. Liposomal Delivery: Liposomes are lipid barriers that resemble cell membranes. This allows them to “fuse” with cells and deliver vitamin C directly inside where it can go to work. Human clinical research shows liposomal vitamin C is nearly 2X better absorbed than standard vitamin C.

3. Vitamin C Concentration: Aim for 500-1000 mg of vitamin C per serving for therapeutic benefits.

4. Whole Food Vitamin C Sources: Real vitamin C is rich in natural cofactors that help it work miracles in the body. There are many sources of whole-food vitamin C, but the absolute best is Amla fruit (Indian gooseberry) extract. Not only is amla unusually rich in vitamin C, but studies show that amla is also the most antioxidant-rich whole food on the planet.

5. Price & Value: Natural liposomal vitamin C is more expensive than cheap synthetic ascorbic acid. However, it is well worth the cost difference when you consider liposomal vitamin C is absorbed nearly 2X better than standard vitamin C. So while it might be a slightly higher investment upfront, you are getting nearly double your money’s worth compared with standard ascorbic acid.

While other brands rely on synthetic ascorbic acid, NativePath’s Liposomal Vitamin C comes from 100% amla fruit extract. This means it delivers both the potent health benefits of real vitamin C, complete with all its natural cofactors—plus amla’s unmatched anti-aging antioxidant payload. What's more, NativePath developed its own groundbreaking Enhanced Liposomal Delivery (E.L.D.) to completely eliminate the need for inflammatory seed oils commonly used in other liposomal formulas. This innovative liquid formula comes in an easy-dispense bottle, making it fast and simple to get your dose of vitamin C even while on the go. We were also impressed with its delicious natural orange flavor, lightly sweetened with monk fruit. It was excellent when added to water, tea, and yogurt. NativePath’s Liposomal Vitamin C formula is hands down the best vitamin C we’ve ever tried or tested. That, combined with its impeccable 365-Day Money Back Guarantee—is why it easily secured the #1 spot on our list.

“I was skeptical because I’ve tried liposomal vitamins in the past that didn’t taste good, but this is actually yummy in my morning water and I look forward to taking it. It’s also a life-saver! I realized after using it for a while that I felt REALLY good. Better than I had in a long time. I’m guessing my old vitamin c was probably pretty useless. My joints feel better and my skin looks so healthy and bright!”

By LivOn

Solid Dose of Synthetic Vitamin C (1000 mg)

Synthetic Vitamin C

Contains Soy

May Be Gentler on the Stomach

Contains 160 mg Sodium

Contains Phospholipids

Problems with Rancidity

Liquid Form

Complaints about Unpleasant Taste & Texture

Liposomal Technology

No Gluten, Dairy, Sugar, or Hexane

Several Complaints of Damaged Product

More Expensive Than Our #1 Pick

LivOn's Lypo-Spheric Vitamin C offers a solid 1,000 mg dose of synthetic sodium ascorbate, which is a little gentler on the stomach than traditional ascorbic acid (although some users still complain of digestive upset). While the liposomal delivery system and essential phospholipids (1,000 mg) may enhance absorption, the formula relies on synthetic vitamin C, rather than the real thing. The liquid format comes in convenient single-serve packets, but many users report that it has an unpleasant flavor and texture. They also complain about mixability and damaged packaging. At $1.33 per serving, it's more expensive than conventional vitamin C supplements, but the enhanced absorption may justify the cost. The formula is free from some allergens like gluten and dairy, but it does contain soy-derived phospholipids and 160 mg of sodium per serving. Despite its popularity, concerns about rancidity, poor texture, and unpleasant taste make it a somewhat risky investment compared to better-formulated liposomal vitamin C options on the market.

By Thorne

Solid Dose of Synthetic Vitamin C (500 mg)

Uses Synthetic Vitamin C

May Cause Stomach Discomfort

Also Contains Natural Citrus Flavonoids

Less Bioavailable Form (Non-liposomal capsule)

Free From Gluten, Dairy, & Soy

Serving Size Is 1 Large Capsule

Thorne's Vitamin C with Flavonoids delivers 500 mg of synthetic vitamin C per serving, although it is enhanced with natural citrus flavonoids that may improve absorption. While the supplement is free from some common allergens like gluten, dairy, and soy, its reliance on synthetic ascorbic acid combined with its difficult-to-swallow capsules knocks it down to number three on our list.

By Beekeeper’s Naturals

Solid Dose of Synthetic Vitamin C (1000 mg)

Most Expensive

Uses Synthetic Vitamin C

Also Contains Bee Propolis Extract

Only 12 Servings

Complaints of Extreme Stomach Pain

Easy-to-Take Liquid Packet

Complaints of Poor Taste

Complaints about Quality Control

Beekeeper's Naturals Propolis + Vitamin C packets combine a solid 1000 mg of synthetic vitamin C per serving with bee propolis extract. Propolis extract is collected by bees and is rich in immune-supporting polyphenols and flavonoids. Despite this promising formulation, the supplement faces serious challenges. Multiple users report severe gastrointestinal issues, including extreme stomach pain and nausea, within 24 hours of consumption. That, plus quality control complaints (like damaged packaging and leaking products) further compounded our concerns. Lastly, it’s the most expensive product on our list—yet uses cheap synthetic vitamin C. It also provides the least number of servings.

By MaryRuth’s

Good Dose of Vitamin C (500 mg)

Uses Synthetic Vitamin C

Contains 4g of Inflammatory Seed Oil

Added 3.4 mg Vitamin E

Liquid Form

Complaints of Unpleasant Flavor and Texture

Liposomal

Naturally Flavored (Orange Vanilla)

Clean Label Project Verified

Certified B-Corp

Made in a GMP Facility

MaryRuth's Megadose Liposomal Vitamin C delivers 500 mg of vitamin C per serving, complemented by 3.4 mg of vitamin E. While the liposomal delivery system aims to maximize absorption, its reliance on sunflower seed oil raises significant concerns around inflammation. Though the product boasts Clean Label Project verification, B-Corp certification, and GMP-certified manufacturing, the high seed oil content equates to nearly a teaspoon of inflammatory oils per dose. This could be particularly harmful for those with cardiovascular concerns or inflammatory conditions. Additionally, reviewers complain about the ultra-sweet flavor and chalky texture. For these reasons, despite its liposomal formulation, MaryRuth’s takes last place on our list.

Traditional vitamin C supplements are poorly absorbed—losing much of their potency as they make their way through the digestive tract. 

Liposomal vitamin C is a cutting-edge form of vitamin C supplement that uses liposome technology to enhance absorption and effectiveness.

Liposomes are tiny, bubble-like structures made of phospholipids. Think of them as protective bubble wrap for vitamin C—safely transporting it through your digestive system and delivering it right into your cells where it can go to work.

Human clinical research shows that liposomal vitamin C is absorbed nearly 2X better than standard vitamin C. 

The key benefits of liposomal vitamin C include:

• Nearly 2X better absorption compared to traditional vitamin C 
• Better protection of the vitamin during digestion
• Less stomach upset
• More efficient delivery to cells where vitamin C is needed

Fun Fact: Did you know that humans are one of the only mammals that can’t produce their own vitamin C? While most animals can synthesize this vital nutrient in their bodies, we must get it entirely from our diet or supplements. This makes vitamin C an "essential" nutrient, meaning it's crucial for our health to get it every day.

By taking a liquid vitamin C supplement daily, you may experience the following science-backed benefits: 

Required to make collagen for healthy skin, hair, nails, & joints

Better cholesterol, blood sugar, blood pressure, & more…

Improves inflammation

Strong year-round immune health

Helps reduce visible signs of aging

Promotes healthy blood vessel function

Supports healthy cortisol levels

Here are seven important things to look for when shopping for a vitamin C supplement...

1.  Natural vs. Synthetic: Choose naturally sourced vitamin C over synthetic ascorbic acid. Natural vitamin C comes with beneficial cofactors and bioflavonoids that enhance absorption and effectiveness. Synthetics are missing these critical cofactors, so they can actually rob your body of minerals like copper.

Look for vitamin C derived from sources like amla, acerola cherry, or camu camu.

2.  Liposomal Formula: Choose a liposomal delivery system for optimal absorption and bioavailability. This advanced technology helps protect the vitamin C and ensures it reaches your cells effectively.

3.  Potency: Look for a supplement that provides between 500-1000mg of vitamin C per serving. This range is both safe and effective for most adults seeking immune and antioxidant support.

4.  Liquid Form: Opt for a liquid vitamin C supplement. Liquid forms are generally more bioavailable and easier to absorb than tablets or capsules.

5.  Clean Ingredients: Examine the "Other Ingredients" section carefully. Avoid supplements containing seed oils (like sunflower oil), soy, artificial sweeteners, colors, and added sugar. The fewer additional ingredients, the better.

6.  Quality Markers: Look for supplements that are:

• Made in cGMP facilities
• Third-party tested for purity and potency
• Free from common allergens
• Transparent about their manufacturing process

7.  Price Per Serving: Calculate the cost per serving rather than just looking at the bottle price. While premium liposomal and natural-source vitamin C supplements may cost more upfront, their superior absorption often makes them more cost-effective in the long run.

“Vitamin C used to always upset my stomach and I never really knew if it was doing anything. This liposomal vitamin C is completely different. I could honestly FEEL the difference after taking it for a few days. I have better energy too. It’s super easy to take and it doesn’t upset my stomach at all. Love it!”

—Kathy A. on 10/31/2024

“I love that it gives me my daily dose of vitamin C from a natural source. I definitely feel like it’s helping me get through the fall while being around so many people. Plus it tastes GREAT!”

—Steve R. on 10/27/2024

“I am a lifelong vitamin C taker—I genuinely think it’s a miracle vitamin. I can honestly say I’ve taken a dozen different brands over my lifetime. Well, I have NEVER taken a vitamin C that made me feel as good as this one did. Pretty quickly I noticed I had better energy, my joints were less achy, and my skin and eyes looked brighter. I was out shopping at the store and ran into a friend who asked me what I was putting on my skin because it looked so smooth. The only thing I’d done differently is start taking this Liposomal Vitamin C!”
