The 5 Best Microgreens for Antioxidants, Ranked for 2026
Red cabbage microgreens can carry up to 147 mg of vitamin C per 100 grams in a 25 variety lab analysis that's the number everybody repeats. It's also only one test.
If you're a home grower trying to find the best microgreens for antioxidants know this first: different lab tests crown different winners. Vitamin C points to one tray, radical scavenging to another, carotenoids to a third.
I sorted the published numbers so you can pick with your eyes open.
The best microgreens for antioxidants split by test. Red cabbage is the best all-around pick, leading on vitamin C and holding up across several tests.
Ruby radish won the largest scavenging comparison, cilantro leads carotenoids, green daikon leads vitamin E and broccoli is the sulforaphane pick.
Below you'll find the three tests that decide any antioxidant ranking and five microgreens ordered by that evidence. I also cover the claims that mislead growers and a quick way to choose your tray.
What Makes a Microgreen Great for Antioxidants? 3 Tests Worth Trusting
Most guides blur three separate tests into one vague antioxidant score that's why the highest antioxidant microgreens change with every new list.
Test one counts vitamins and carotenoids. NCCIH uses vitamins C and E and beta-carotene as its examples of familiar dietary antioxidants. A Maryland and USDA team then measured vitamin C, vitamin E and carotenoids in 25 microgreens.
Test two measures radical scavenging usually with the DPPH assay that's a different question from vitamin content. A tray can ace one test and flop another.
Test three tracks compounds that work indirectly like the glucosinolates that become sulforaphane.
Those matter. They just don't show up in a vitamin tally.
The 5 Best Microgreens for Antioxidants: Ranked
I ranked the best microgreens for antioxidants on how many independent tests each one wins, not on one splashy number.
1. Red Cabbage: The Best All Around Pick
Red cabbage won vitamin C in the biggest early test. Maryland food scientist Qin Wang's team analyzed 25 microgreens. They found red cabbage carrying six times the vitamin C and 40 times the vitamin E of the mature plant.
"…we had to rush to double and triple check them."
Dr. Qin Wang, Nutrition and Food Science, University of Maryland
A separate six crop comparison ranked red cabbage first for vitamin C and DPPH scavenging. Red radish and mustard were among the five crops it beat.
That repeat performance is why it's number one. Red cabbage microgreens nutrition data lands near the top in more than one lab which beats a single record.
2. Ruby Radish: Winner of the Biggest Scavenging Test
Among 30 Brassicaceae varieties, ruby radish posted the highest total phenolics and the highest DPPH score. DPPH values ran from 157.3 to 806.3 micromoles of Trolox equivalent per 100 grams, a five fold spread.
The same study reported large gaps within species so the cultivar name on the seed packet matters. The highest antioxidant microgreens on this test come with a variety name so buy ruby radish seed by name.
3. Cilantro: The Carotenoid Leader
Cilantro had the highest carotenoid concentrations among 25 microgreens. It also carried three times the beta carotene of mature cilantro.
Beta carotene is one of the big three so cilantro earns a small tray. Taste divides people. Grow a little and decide.
4. Broccoli: The Sulforaphane Pick
Broccoli plays a different game. Broccoli sprouts held 10 to 100 times more glucoraphanin than mature plants and glucoraphanin is the glucosinolate that becomes sulforaphane.
Broccoli microgreens sulforaphane potential is the reason to grow it not scavenging scores.
📝 Note: Treat sulforaphane claims with care. That 10 to 100 times figure describes 3 day old sprouts and the precursor not a dose from a tray you cut at day ten.
5. Green Daikon Radish: The Vitamin E Leader
Green daikon radish had the highest tocopherol concentrations the vitamin E family, of the 25 varieties tested.
Vitamin E is the third of the big three. Run daikon beside red cabbage and you cover vitamins C and E with two trays. Two trays, two vitamins.
Five microgreens, five different antioxidant wins
Microgreen | Best For | Standout Figure | Source |
|---|---|---|---|
Red cabbage | Vitamin C, all around pick | Up to 147 mg vitamin C per 100 g; 6x the mature plant | Xiao et al., 2012; Dhaka et al., 2023 |
Ruby radish | Radical scavenging, phenolics | Top DPPH score of 30 varieties (157.3 to 806.3 range) | Xiao et al., 2019 |
Cilantro | Carotenoids, beta carotene | Highest carotenoids of 25; 3x the beta carotene of mature cilantro | Xiao et al., 2012 |
Broccoli | Sulforaphane precursor | 10 to 100x glucoraphanin in sprouts vs mature plants | Fahey et al., 1997 |
Green daikon radish | Vitamin E | Highest tocopherols of 25 varieties | Xiao et al., 2012 |

Why Most Growers Get Microgreen Antioxidant Claims Wrong
The up to 40 times headline is a ceiling not an average. Researchers reported four to 40 fold gaps across varieties. The 40 came from vitamin E in red cabbage microgreens nutrition data while vitamin C in the same plant was six fold.
Microgreens vs mature vegetables nutrition comparisons also run per gram. A handful of microgreens weighs far less than a bowl of mature leaves so per gram multipliers don't turn into per meal wins.
You'll also read that cilantro won "antioxidant capacity" in the USDA study. Wrong test. That study measured vitamin C, carotenoids, vitamin K and vitamin E not scavenging capacity.
Skip the pills. Current evidence doesn't support antioxidant supplements for preventing cancer or heart disease and high dose beta carotene may raise risk. People who eat more vegetables and fruit do show lower risks of chronic disease.
I'd spend the money on seeds. If you're in cancer treatment check with your oncology team before adding any antioxidant supplement.
How to Choose Your Tray Without Second-Guessing the Lab Data
Know your target first because the best microgreens for antioxidants depend on what you're measuring.
Vitamin C goes to red cabbage and raw scavenging to ruby radish. Carotenoids go to cilantro, vitamin E to green daikon and broccoli microgreens sulforaphane to anyone chasing that compound.
Then rotate. One tray on repeat leaves holes in your coverage.
💡 Pro Tip: Start with two trays, red cabbage and ruby radish. They cover vitamin C and radical scavenging the two wins I trust most.
Last, grow clean. Fuzzy white threads can be harmless root hairs or real mold. Telling them apart is a skill worth learning before you eat.
A sour smell is a stop sign. Trace the cause before the tray reaches your plate.
Key Takeaways
- No single microgreen wins every test so the highest antioxidant microgreens depend on what you measure.
- Red cabbage microgreens nutrition data tops vitamin C in two separate labs which makes it the most consistent performer.
- Ruby radish led the largest radical scavenging comparison across 30 Brassicaceae varieties.
- The "up to 40 times" headline is a ceiling tied to vitamin E in red cabbage not an average.
- Microgreens vs mature vegetables nutrition multipliers are per gram so they overstate what lands on a plate.
Labs keep testing new varieties so the best microgreens for antioxidants will keep shifting. Until a bigger head to head lands I'd run red cabbage and ruby radish side by side and let the next paper settle the argument.
Frequently Asked Questions
Which microgreen has the most health benefits?
No single microgreen wins every test. The best microgreens for antioxidants by consistency are red cabbage and ruby radish. Broccoli microgreens sulforaphane potential sets broccoli apart.
What are the big 3 antioxidants?
Vitamin C, vitamin E and beta carotene are the three most familiar antioxidants. Microgreens carry all three but different varieties lead each one. In the 2012 USDA backed test, red cabbage led vitamin C, green daikon radish led vitamin E and cilantro led carotenoids.
What are the top 5 microgreens to grow for antioxidants?
Red cabbage, ruby radish, cilantro, broccoli and green daikon radish are the best microgreens for antioxidants by published lab data. Each wins a different test. Start with red cabbage and ruby radish, then add one more.
Are microgreens really 40 times more nutritious than mature vegetables?
Only in specific pairings. The 40 fold figure was vitamin E in red cabbage and gaps across varieties ran from four to 40 fold. Microgreens vs mature vegetables nutrition differences depend on the plant and the nutrient.
Should I take antioxidant supplements instead?
No. Evidence doesn't support supplements for preventing cancer or heart disease and high dose beta carotene may raise lung cancer risk especially in smokers. Food is the safer route.
