HistaQuel® Comprehensive Mast Cell Support

HistaQuel® is a targeted formula designed to support healthy mast cell function and balanced histamine response throughout the body.

This makes it a systemic approach to everyday allergy and immune support.

HISTAQUEL FAQSCommon questions about Researched Nutritionals HistaQuel
What is Researched Nutritionals HistaQuel used for?

Researched Nutritionals HistaQuel is designed to support healthy mast cell function, balanced histamine response, immune system balance and everyday allergy support. It provides flavonoids and botanical extracts for systemic histamine and immune-signalling support.

How is HistaQuel different from a DAO enzyme product?

HistaQuel supports mast cell function, histamine release and immune balance throughout the body. DAO enzyme products mainly support the breakdown of dietary histamine in the digestive tract, so they work in a different way.

What are the key ingredients in Researched Nutritionals HistaQuel?

Researched Nutritionals HistaQuel contains Mast Cell Secure™, featuring quercetin phytosome, Perilla frutescens seed extract, luteolin and fisetin, plus HistaCheck™, featuring black cumin seed extract and stinging nettle leaf extract.

What does quercetin do in HistaQuel?

Quercetin is a plant flavonoid commonly used to support mast cell stability, immune balance and histamine response. HistaQuel uses Quercefit® quercetin phytosome to support improved absorption compared with standard quercetin.

Why does HistaQuel contain luteolin and fisetin?

Luteolin and fisetin are flavonoids included to support mast cell regulation, antioxidant activity and balanced immune signalling. They complement quercetin as part of the broader Mast Cell Secure™ blend.

What do black cumin seed and stinging nettle do in HistaQuel?

Black cumin seed and stinging nettle are botanicals commonly used to support immune balance, seasonal comfort and histamine response. In HistaQuel, they form the HistaCheck™ blend for additional histamine-support activity.

Is HistaQuel an antihistamine medication?

No. HistaQuel is not an antihistamine medication. It is a nutritional and botanical supplement designed to support healthy histamine response and mast cell function, not block histamine receptors like conventional antihistamine medicines.

How do you take Researched Nutritionals HistaQuel?

Adults can take 2 capsules twice daily, with or without meals, or as directed by a healthcare professional. Follow the label directions and do not exceed the recommended dose unless professionally advised.

Can I take HistaQuel with other histamine or allergy supplements?

Use caution when combining HistaQuel with other quercetin, nettle, black cumin, DAO enzyme, vitamin C, antihistamine, immune or allergy-support products. Overlapping histamine-support products may not be necessary unless professionally advised.
