Best Luteolin Supplements

Reviewed by Dr Muhammad Zeeshan Afzal (MBBS | FCPS | MRCP) — independent product reviewer and content creator for Welzo. Last updated 3 July 2026.

Luteolin is one of the most interesting flavonoids in the wellness world — a plant compound studied for antioxidant, anti-inflammatory, neuroprotective, mast-cell and even senolytic (senescent-cell-clearing) properties, and increasingly popular with the histamine, longevity and brain-health communities. But the supplement market is crowded, doses range from a token 50 mg to 500 mg, purity varies widely, and some products hide their plant source. This guide compares the best luteolin supplements available to UK buyers on the criteria that actually matter — purity, dose, absorption, testing and value — explains the benefits and the honest state of the evidence, and answers the questions people most often ask.

How We Ranked the Best Luteolin Supplements

Each product was assessed against seven criteria: purity (standardisation and plant source); dose of actual luteolin per serving; form and bioavailability; third-party testing and contaminant screening; UK accessibility (dispatch, delivery, returns); value; and transparency (clear labelling, no hidden proprietary blends). Because luteolin content and quality vary so widely between products, dose and purity carried the most weight — a "high-strength" label means little if the actual luteolin content or purity is low.

The 6 Best Luteolin Supplements Reviewed

1. Welzo Ultra Purity Luteolin 500 — Best Overall (4.8/5)

Luteolin	500 mg	Form	Capsule
Testing	Third-party, GMP	UK dispatch	Yes
Label	Clean, no blends	Overall	4.8 / 5

The Welzo Ultra Purity Luteolin 500 tops the list because it solves the two biggest problems in this category at once: dose and purity. At 500 mg of luteolin per serving, it's one of the highest-strength single-ingredient luteolin capsules available to UK buyers — most competitors sit at 50–200 mg. It's part of the Welzo Ultra Purity™ range: manufactured to strict quality standards, third-party tested for ingredient identity, potency and contaminants, and transparently labelled with no proprietary blends or unnecessary fillers. It dispatches from the UK with fast delivery and a 14-day returns policy, and is priced competitively against premium niche brands. For anyone who wants a serious, clearly-dosed, well-tested luteolin without paying a boutique premium, it's the standout.

Pros: high 500 mg dose; third-party tested; transparent clean label; GMP; UK dispatch and returns; strong value.
Considerations: the high dose suits those wanting maximum strength — if you're sensitive or new to luteolin, start with a lower amount; very popular, so can sell out.

Verdict: the best all-round luteolin supplement for UK buyers on dose, purity and value. View Welzo Ultra Purity Luteolin 500 →

2. Double Wood Luteolin — Best Value Standardised (4.5/5)

Luteolin: 100 mg per serving · Purity: standardised to 98% from sophora japonica.

Double Wood is a deservedly popular value pick. Its luteolin is standardised to 98% from sophora japonica (not a peanut-shell source, which matters for allergy-conscious buyers), every batch is made in a cGMP facility and third-party tested for identity, potency and contaminants including heavy metals. At 100 mg per serving it's a sensible everyday dose, and the price per bottle is hard to beat. The main trade-off versus our top pick is the lower per-serving dose.

Verdict: excellent value and transparency — the best budget-friendly standardised luteolin.

3. Vitality Pro Luteolin — Best UK Alternative (4.4/5)

Luteolin: 100 mg per capsule (90 capsules) · Purity: up to 99.8% (recent batch), from sophora japonica · Origin: UK.

Vitality Pro is a UK longevity-focused brand that frames luteolin within a healthy-ageing and senescence context. It's made to GMP and ISO 9001 standards with independent batch testing (recent batches verified at up to 99.8% purity), is vegan and free from common allergens, and dispatches from the UK. The brand highlights luteolin's senolytic potential and its role as a CD38 inhibitor — a nice detail, since CD38 consumes NAD+, so this is partly why luteolin appears in longevity stacks. The dose is lower than our top pick, so factor that into value.

Verdict: a high-purity UK alternative with strong transparency and a longevity/senolytic framing.

4. Nutricost Luteolin with Rutin Complex — Best Luteolin + Rutin (4.1/5)

Luteolin: 100 mg (+ rutin) · Count: 120 capsules · Brand: GMP, lab-tested value brand.

Nutricost pairs 100 mg of luteolin with rutin — a flavonoid that naturally co-occurs with luteolin and is often used for vascular and antioxidant support — in an affordable, high-count bottle from a widely-trusted value brand that manufactures in GMP-compliant, FDA-registered facilities. The dual-flavonoid approach appeals to those wanting broader antioxidant coverage at a low price per serving.

Verdict: the best-value luteolin-plus-rutin complex for broad, everyday flavonoid support.

5. NeuroProtek (Algonot) — Best for Mast-Cell / Histamine Focus (4.0/5)

Formula: luteolin + quercetin + rutin in an olive-oil base (lipid softgel).

NeuroProtek takes a formulated, "medical-grade" approach favoured in the mast-cell activation (MCAS) and neuroinflammation communities: a flavonoid trio delivered in an olive-oil lipid base intended to enhance absorption — a genuinely useful feature given luteolin is fat-soluble. It's the go-to for people specifically stacking flavonoids for histamine and brain-fog support. Trade-offs: it's a blend rather than a high single-dose luteolin, and the softgels sit at a premium price; start low if sensitive.

Verdict: the specialist, absorption-focused choice for those building a flavonoid protocol around mast-cell and histamine support.

6. Nutricost Luteolin Capsules — Best Budget Single-Ingredient (3.9/5)

Luteolin: 100 mg per serving · Brand: GMP, non-GMO, lab-tested.

If you simply want plain luteolin at the lowest sensible price, Nutricost's single-ingredient capsules are a no-frills option: 100 mg per serving, non-GMO, gluten-free, made in a GMP-compliant, FDA-registered facility, and third-party tested. There's nothing fancy here — no added ingredients or premium delivery system — which is exactly the point for budget-conscious buyers building their own stack.

Verdict: the cheapest reliable way to add straightforward luteolin to your routine.

What Is Luteolin? Sources & How It Works

Luteolin is a naturally occurring flavone — a type of plant flavonoid — found in foods such as celery, parsley, chamomile, thyme, green peppers, carrots and citrus. In supplements it's extracted and concentrated (commonly from sophora japonica or, in some products, peanut shells) to provide a far higher amount than diet alone typically delivers. Mechanistically, luteolin is studied as an antioxidant that helps neutralise free radicals; in laboratory research it interacts with inflammatory signalling pathways (such as NF-κB and AP-1) and with mast cells, the immune cells involved in histamine release; and it has been described as a CD38 inhibitor and a senolytic that may help clear senescent ("aged") cells. It's this combination of properties that underpins the interest in luteolin — though, as we cover below, most of this evidence is still early.

Luteolin Benefits

Here's what luteolin is most commonly taken for, framed honestly around what the research supports:

• Antioxidant support: luteolin is a potent antioxidant that helps protect cells from oxidative stress — its best-established property.
• Supporting a normal inflammatory response: studied in preclinical models for modulating inflammatory signalling (NF-κB and AP-1 pathways).
• Brain and cognitive health: researched for neuroprotective properties; luteolin can cross the blood-brain barrier, and it's popular with those seeking mental clarity and "calm focus".
• Mast-cell and histamine balance: a key reason for its popularity in the histamine-sensitivity and MCAS communities, based largely on preclinical mast-cell research.
• Immune support: flavonoids like luteolin are studied for their role in balanced immune function.
• Longevity & senescent cells: researched as a senolytic that may help clear senescent cells, and as a CD38 inhibitor that may help preserve NAD+ — which is why it appears in longevity stacks.
• Cardiovascular and skin support: as an antioxidant flavonoid, often included for general wellness and healthy-ageing routines.

These are areas of support and study, not proven treatments. Luteolin is a wellness supplement, not a medicine.

What the Research Actually Shows (An Honest Look)

It's worth being straight about the evidence, because a lot of luteolin marketing overstates it. Much of the promising data is preclinical — cell and animal studies. For example, laboratory research shows luteolin can block the NF-κB and AP-1 inflammatory pathways in immune cells,¹ and can protect cells from oxidative-stress-induced senescence by modulating SIRT1 and p53.² Several of the most-cited human findings actually come from combination products: a formulation of palmitoylethanolamide (PEA) with a small amount of luteolin has been studied in small trials for cognitive and neurological outcomes, including a randomised controlled trial in long-COVID.³ But that's a PEA-plus-luteolin combination, not luteolin alone, and the trials are small. The honest summary: luteolin is a plausible, well-tolerated antioxidant flavonoid with encouraging early research, but robust large-scale human trials on luteolin by itself are limited. Choose it on quality, keep expectations measured, and don't use it to replace prescribed treatment.

How to Choose a Luteolin Supplement

What to check	Why it matters
Purity / standardisation	Look for high purity (ideally standardised to 95%+ luteolin). Low-purity extracts deliver less active compound.
Actual luteolin dose	Read the label for luteolin content per serving, not just capsule weight — doses range from 50 mg to 500 mg+.
Plant source	Some luteolin is extracted from peanut shells — important if you have a peanut allergy. Sophora japonica is a common alternative.
Third-party testing	Independent testing for identity, potency and contaminants (heavy metals) is a baseline for quality.
Form / absorption	Luteolin is fat-soluble and poorly water-soluble; lipid-based formats or taking it with fat help uptake.
Clean label	Avoid proprietary blends that hide individual amounts, and unnecessary fillers.
UK dispatch	For UK buyers, UK-based dispatch avoids import charges and simplifies returns.

Luteolin Dosage

There's no official recommended dose, but based on how luteolin is commonly used and studied:

• Common range: around 100–300 mg per day.
• High-strength: some products (like the Welzo Ultra Purity Luteolin 500) provide 500 mg for those wanting a higher dose.
• Starting out: if you're new to luteolin or have a sensitive stomach, start at the lower end and take it with food, ideally a meal containing some fat.

Consistency matters more than a single large dose. Follow the product label and don't exceed the stated amount without professional advice.

Bioavailability & Absorption

Luteolin's main practical limitation is that it's fat-soluble and poorly water-soluble, so absorption from a plain powder can be modest. Three things help: taking it with a fat-containing meal (a little olive oil, avocado or yoghurt); choosing a lipid-based format such as the olive-oil softgels used by NeuroProtek; and, for some users, pairing with other flavonoids like quercetin. That said, a higher-dose standard capsule can still deliver a strong total amount of luteolin — so weigh dose, purity and format together rather than assuming any single format automatically wins.

How Long Does Luteolin Take to Work?

Flavonoids accumulate in tissues gradually. Some people notice subtle changes (often described as clearer focus or feeling "less reactive") within 1–2 weeks, while antioxidant and other effects may take around 3–6 weeks of consistent daily use. Give any luteolin supplement at least a month before deciding whether it's working for you.

Who Should Consider Luteolin?

Luteolin tends to appeal to people interested in: general antioxidant and healthy-ageing support; brain and cognitive wellness; histamine sensitivity or mast-cell support (as an adjunct, not a replacement for medical care); and building a longevity/flavonoid stack. If you fall into the histamine/MCAS group in particular, treat luteolin as a complement to — not a substitute for — advice and treatment from your GP or specialist.

Luteolin vs Quercetin vs Apigenin

These three flavonoids are often mentioned together, and they're complementary rather than interchangeable:

Flavonoid	Best known for	Notes
Luteolin	Antioxidant, mast-cell/neuro interest, senolytic	Fat-soluble; benefits from lipid delivery; crosses the blood-brain barrier.
Quercetin	Antioxidant, histamine/immune support	The most widely used flavonoid; commonly stacked with luteolin.
Apigenin	Calm/relaxation, CD38 & longevity interest	Popular in evening and longevity stacks.

Many people combine luteolin with quercetin for broader antioxidant coverage. Introduce one at a time so you can judge tolerability.

Stacking Luteolin

Luteolin pairs naturally with other antioxidant and longevity compounds. These verified Welzo options cover complementary roles:

Pairing	Why	Option
Quercetin	Complementary flavonoid, commonly stacked with luteolin	Welzo Quercetin range
Astaxanthin	Lipid-soluble antioxidant support	Welzo Ultra Purity Astaxanthin
Spermidine	Autophagy and cellular-renewal support	Welzo Ultra Purity Spermidine
NMN	NAD+ support for a longevity routine (luteolin may help preserve NAD+ via CD38)	Welzo Ultra Purity NMN

Explore the full Welzo Ultra Purity range, the antioxidants collection, or the longevity supplements collection to build a routine. If your interest is seasonal or histamine-related, you may also find the allergy & hay fever range useful alongside professional advice.

Side Effects, Safety & Interactions

Luteolin is generally well tolerated, but because this is a health decision, take sensible precautions:

• Most common effect: mild digestive upset, usually reduced by taking it with food.
• Medication interactions: luteolin can inhibit cytochrome P450 enzymes and may interact with blood-thinning/antiplatelet medicines (such as warfarin), certain chemotherapy agents, and some antibiotics. Check with your GP or pharmacist if you take any prescription medication.
• Allergen source: if a product's luteolin is extracted from peanut shells, avoid it if you have a peanut allergy — check the label or choose a sophora japonica source.
• Pregnancy & breastfeeding: safety isn't established — don't use without advice from your GP or midwife.
• Under-18s: not intended for use.

Food supplements support — not replace — a balanced diet and healthy lifestyle, and are not a substitute for professional medical advice, diagnosis or treatment.
