FIQ Histamine IQ

The ingredients in Histamine IQ:

• Enhance histamine metabolism*
• Support healthy mast cell function*
• Promote balanced cellular immune response*
• Reduce inflammatory actions of histamine*

Diamine oxidase (DAO) from porcine kidneys aids in the breakdown of histamines released from cells or consumed with food. Nettle and quercetin assist in blocking the production and release of histamine. Ursolic acid helps block the degranulation of mast cells – the primary histamine-releasing cells. Holy Basil blocks H-1 and H-2 receptors, and Bromelain’s broad anti-inflammatory actions influence various systems related to histamine release, response, and breakdown.*

Active Ingredients: DAO (Diamine Oxidase) from porcine kidney – 4mg, Holy Basil Extract 2.5% Total, Ursolic Acid 300mg, Quercetin, Dihydrate 95% – 300mg, Stinging nettle extract-200mg, Bromelain 2400GDU / G – 200mg

Other ingredients: Methylcellulose Capsule

What is FIQ Histamine IQ?

It's described as the first full-spectrum histamine support supplement, combining a DAO enzyme with several plant-based compounds to support balanced histamine release and clearance.

What does histamine do in the body, and why would someone need to manage it?

The body makes histamine naturally, and a certain amount is needed to regulate sleep and wakefulness, digestion, and cognitive function. Problems arise when too much histamine builds up, or it's triggered inappropriately, which can lead to allergy symptoms, gastrointestinal issues, rashes, and headaches.

What does the DAO enzyme do specifically?

Diamine oxidase, sourced from porcine kidney here, helps break down histamine that's either released from the body's own cells or consumed through food. This is the same clinically studied source used in DAO research for histamine metabolism.

What do nettle and quercetin add?

Both work to help block the production and release of histamine in the first place, complementing the DAO enzyme's role in breaking down histamine that's already present.

What does ursolic acid, from the Holy Basil extract, do?

Ursolic acid helps block degranulation of mast cells, which are the primary cells responsible for releasing histamine, so this works upstream of both the nettle and quercetin action and the DAO breakdown process.

What role does Holy Basil's other activity play, beyond ursolic acid?

Separately from the ursolic acid content, Holy Basil is also noted for blocking H1 and H2 histamine receptors, which are involved in triggering allergy type symptoms.

Why is bromelain included in a histamine formula?

Bromelain's broad anti-inflammatory action is included to support various systems connected to histamine release, response, and breakdown, working alongside the other targeted ingredients.

What's the suggested dose?

Take 2 capsules daily, or as directed by a healthcare professional. Some users work up to this gradually, for example starting with one capsule every other day, especially if pill-swallowing is a challenge, though the full recommended dose is twice daily.

Who might use this product?

People dealing with seasonal allergies, sinus congestion, hay fever type symptoms, or broader signs of histamine intolerance, particularly those looking for a combination approach rather than a single ingredient antihistamine support product.

Is this suitable for vegetarians, vegans, kosher, or halal diets?

No. Even though the capsule shell itself is vegetable based, the DAO enzyme is porcine derived, which makes the overall product unsuitable for any of those dietary practices.

Are there any precautions?

As with any new supplement, consult a healthcare professional before use if you're pregnant, nursing, have or suspect a medical condition, or are taking other medications. Bromelain in particular can have a mild blood thinning effect, so it's worth checking with a provider if you're on anticoagulant medication.

How should it be stored?

Store in a cool, dry place, and don't use if the safety seal is broken or missing. Keep out of reach of children.
