That is the whole formula, and the label says what it is for: supporting a balanced immune system. Two ingredients, one capsule, twice a day with food.

Straight off the panel. No proprietary blend, no filler list dressed up as an ingredient.
- 1Quercetin, 500 mgFrom quercetin dihydrate. One capsule is one serving.
- 2Bromelain Powder, 100 mgIn the same capsule, at the same serving.
- 360 capsules per bottle60 servings. Those two ingredients are the whole active formula.
What It Supports
These four lines are the ones on the product page today. They have not been rewritten, stretched, or added to.
What The Front Of The Bottle Says
Four things are printed on the label. Here they are, in the same words.
Three Things To Know Before You Start
- 1Adults only.The label is explicit about it. This is not a formula for children.
- 2Take it with food.Suggested use is one capsule two times daily, with food, or as recommended by a health care practitioner.
- 3Check first if this is you.Pregnant women, lactating women, and anyone taking medication should consult a health care professional before using any nutritional product.
One Capsule, Twice A Day. 30 Days A Bottle.
No marketing number. Here is the arithmetic, and every input is printed on the bottle.
- 1One capsule, two times daily.Straight off the Suggested Use panel on the back label.
- 2That is 2 capsules a day.With food, spaced out across the day.
- 360 capsules in the bottle.60 divided by 2 is 30. One bottle is a 30-day supply, which is exactly what the 1-bottle tile says.
Three bottles is 90 days. Six bottles is 180 days. That is why the subscription cadence is set the way it is.
What Is Not In It
The short list matters as much as the ingredient list.
No Artificial Extras
Contains no artificial preservatives, colors or sweeteners. That is printed on the panel.
Non-GMO Formula
Stated on the front of the bottle and again under the Supplement Facts panel.
Vegetable Capsule
Hypromellose, not gelatin. The label reads Vegan, and the capsule is why.
What’s Inside
Two active ingredients. One capsule. Everything below is read straight off the Supplement Facts panel.
-
Quercetin500 mg, from quercetin dihydrateThe ingredient the formula is named for, at 500 mg in a single capsule. It is listed on the panel on its own, not inside a proprietary blend, so you can see exactly what you are getting per serving.
-
Bromelain Powder100 mgThe second active ingredient, in the same capsule at the same serving. Also listed at its own dose on the panel.

Ask Dr. Martin
How many capsules are in a bottle, and how long does one last?
60 capsules. The Supplement Facts panel says 60 servings per container, and the front of the bottle says 60 capsules.
Suggested use is one capsule two times daily, so two a day. That makes one bottle a 30-day supply.
Three bottles is 90 days. Six bottles is 180 days.
How do I take it?
Adults only. As a dietary supplement, take 1 capsule 2 times daily, with food, or as recommended by a health care practitioner.
That is the suggested use printed on the bottle. No timing tricks, no cycling on and off.
What is actually in it?
Two active ingredients per capsule: Quercetin 500 mg, from quercetin dihydrate, and Bromelain Powder 100 mg.
Other ingredients are hypromellose (the vegetable capsule), microcrystalline cellulose, vegetable magnesium stearate, and silicon dioxide.
Both actives are listed at their own dose. There is no proprietary blend hiding the amounts.
Dr. Martin on this
Is it vegan? Is it non-GMO?
Yes to both. The front of the bottle reads Non-GMO and Vegan, and the capsule itself is hypromellose rather than gelatin.
It also contains no artificial preservatives, colors or sweeteners.
I have a food allergy. What should I know?
Read this one carefully. This product is manufactured and packaged in a facility which may also process milk, soy, wheat, egg, peanuts, tree nuts, fish and crustacean shellfish.
If any of those are a problem for you, speak to your health care professional before starting.
Can I take this if I am pregnant, nursing, or on medication?
Ask first. The label is clear: pregnant women, lactating women, and anyone taking medications should consult a health care professional before using any nutritional product.
If any adverse reaction occurs, stop and speak to a health care professional.
What if it isn’t for me?
Send it back. 60-day money-back guarantee, no questions asked, even the empty bottle.
There isn’t much more to say about this one, and that is the point.
Quercetin and bromelain, 500 mg and 100 mg, in one capsule. Doctor formulated, non-GMO, vegan, with both doses printed on the panel where you can check them.
60 Capsules. 30 Days. Give It A Fair Shot.
Take it the way the label says, one capsule twice a day with food, and give it a real run before you decide. The 60 days are on us either way.
