Best Luteolin
Supplements in 2026

An Honest Comparison

Luteolin is one of the more interesting flavonoids in the nutritional research space right now. Most of the search interest comes from three areas: mast cell research (NeuroProtek and its relatives), fructose metabolism research (LIV3 Health SugarShield), and the general flavonoid wellness category (everything else).

If you have landed on this page, you are probably trying to figure out which one is right for you. We are the maker of LIV3 Health SugarShield, so any roundup we publish has a built-in commercial interest. We have tried to write this one honestly. Where another product is a better fit for what you are trying to do, we say so. The luteolin supplements below are arranged by what we consider the strongest formulation and transparency standards first, and we explain our reasoning.

Luteolin per serving Delivery Lab results Cost/serving
LIV3 Health SugarShield 250mg(98% Sophora japonica) Liposomal (sunflower lecithin) Published per batch $0.83
NeuroProtek (Algonot) 100mg(Citrus paradisi extract) Liposomal(olive pomace oil) Not publicly published ~$1.83
Standard Amazon luteolin (representative) Often labeled 600–1,000mg Standard capsule (not liposomal
at the dose claimed) Generally not published $0.20–$0.50
Pure Encapsulations 100mg Standard capsule GMP, in-house testing ~$0.60
Swanson Luteolin Complex 100mg + rutin Standard capsule GMP, in-house testing ~$0.30

1. LIV3 Health SugarShield

Active luteolin:

250mg per serving from a 98% Sophora japonica extract. Delivery: liposomal on a sunflower lecithin base. Additional active: tart cherry (Prunus cerasus) 30:1 extract.

Best fit for:

buyers specifically interested in fructose metabolism and the fructokinase pathway. The dose is substantially higher than most other luteolin supplements, the delivery system addresses the flavonoid bioavailability problem, and the formulation pairs luteolin with tart cherry, which is studied for uric acid and antioxidant activity, both directly relevant to the fructose-metabolism story.

Transparency:

Third-party lab results published per batch on liv3health.com. Manufactured by Best Formulations, a leading U.S. contract supplement manufacturer, in a cGMP California facility. Per-ingredient milligram doses disclosed on the supplement facts panel.

Why we list it first:

Because we built it, and because we believe the combination of dose, delivery, and transparency is the strongest of any luteolin product currently on the market for the fructose-metabolism use case. We are not impartial. Apply your own judgment.

2. NeuroProtek (Algonot)

Active luteolin:

100mg per softgel from Citrus paradisi (grapefruit) seed extract.
Delivery: liposomal on olive pomace oil. Additional actives: quercetin 70mg, rutin 30mg.

Best fit for:

Buyers focused on mast cell research and neuroinflammation. NeuroProtek has the longer track record in that specific research community, and the combination of luteolin, quercetin, and rutin is a familiar one in mast cell literature.

Transparency:

Third-party lab results are not publicly published on the Algonot website at time of writing.

Why we list it second:

NeuroProtek is the most established luteolin product in its category and has a legitimate research community behind it. For mast cell use cases,
it is a serious option. The lower dose and the lack of publicly published lab results are the two reasons it is not first on this list for the broader category.

3. Amazon "High-Dose" Liposomal Luteolin (Various Sellers)

Active luteolin (claimed):

often 600mg, 800mg, or even 1,000mg per serving. Delivery: marketed as liposomal but rarely formulated as such at the claimed dose.

Best fit for:

Honestly, no one. We have written a separate page on the high-dose Amazon luteolin category and the dosage math problem. The short version: most of these products advertise doses that are mechanically inconsistent with capsule capacity and the formulation requirements of a true liposomal product. If you see a luteolin supplement on Amazon claiming 800mg per serving for under fifteen dollars a bottle, the label is almost certainly not telling the whole story.

Why we list it last:

Because someone landing on this page from an Amazon comparison search needs to know that the high-dose category is, with rare exceptions, not what it appears to be on the label.

"When I evaluate any supplement, the first thing I look at is whether the dose on the label is consistent with what the research supports and what the manufacturing process can actually deliver.

Luteolin is a good example of a flavonoid where the marketed dose
and the absorbed dose are very different numbers, and a careful buyer
should understand the distinction.

The transparency standards a brand applies to its own product, including
third-party lab results, are usually a reasonable proxy for whether the formulation has been built honestly."

How to Choose a
Luteolin Supplement

The four questions worth asking before you buy any luteolin product:

What dose is on the label, and is the dose consistent with the research that justifies it?

Standard luteolin doses in published research range from roughly 100mg to 400mg, depending on the application. Doses substantially above that range, particularly on inexpensive products, are a flag rather than a feature.

Is the product liposomal, and if so, is the liposomal claim believable?

True liposomal formulation requires specific manufacturing capability and a phospholipid carrier (sunflower lecithin, olive pomace oil, soy lecithin) that should be disclosed on the label. A product that claims to be liposomal but does not name the carrier is suspect.

Are third-party lab results published?

This is the single best transparency signal. If a brand will not publish lab results for the batch you are buying, you are trusting the label without verification.

Does the supporting ingredient stack match what you are trying to do?

Luteolin paired with tart cherry suggests a metabolic and antioxidant focus. Luteolin paired with quercetin and rutin suggests a mast cell focus. Luteolin alone is the simplest formulation. None of these is wrong; they are just different applications.
