Intaq checks every supplement you take against your medicines, your conditions and each other, then tells you plainly what to change, in words a person can act on.
Not advised if you use hormonal birth control. St John's wort speeds up the breakdown of birth control hormones, which can cause breakthrough bleeding, and unintended pregnancies have been reported.
A real check from the Intaq app, run on 16 October 2026.
Three more real checks
Betaine HCl 650 mg with Maalox
Take with caution — see the note below
Use with care if you take an antacid such as Maalox, Mylanta, Rolaids or Tums and your betaine is the hydrochloride (HCl) form. Betaine HCl adds stomach acid and an antacid neutralises it, so each can weaken the other. Take them at least 2 hours apart.
Phenylethylamine HCl 500 mg, no medicines
Avoid — not safe for you as dosed
Phenylethylamine HCl: 500 mg is above the evidence-based ceiling of 250 mg.
Vitamin D3 25 mcg with Lisinopril 10 mg
No profile conflict found — but this is a partial check, not a clearance
Nothing found against you. Some checks have no data for this product yet.
Checked on 16 October 2026. Each check uses the age, sex and medicines of a sample person; yours will use your own.

Why we built Intaq
I have designed supplement formulas for more than ten years. In that time I have watched too many people choose a supplement because of what its label promises, without anyone asking about the rest of their life: the medicines they take, the conditions they live with, what they eat and how they live.
Those things can change what a supplement does to you.
Some of the clashes are common
St John's wort can make the birth-control pill work less well.
Licorice root can raise blood pressure, which matters if yours is already high.
High-dose beta-carotene raised the risk of lung cancer in smokers in two large trials.
Others are rare, and easy to miss
Ketone (BHB) supplements taken with an SGLT2 diabetes medicine such as Jardiance can add to the risk of ketoacidosis.
5-HTP taken by someone who also takes methylene blue can bring on serotonin syndrome.
For someone with Wilson's disease, extra copper, from a supplement or from foods such as oysters, builds up in the body.
Intaq is the check I wish each of them had had: one that looks at the whole person before the supplement. It never diagnoses or prescribes. It gives you, and the people who care for you, a clear picture to decide from.
— Intaq's founder
Built to be careful
Intaq never diagnoses, treats or prescribes. Every caution it gives you traces back to published evidence, and when the evidence does not cover a combination the app says it does not know rather than guessing. Pregnancy, breastfeeding, age, allergies and an upcoming operation are all taken into account. Read how Intaq stays careful.
Who it is for
People on medicines
If you take even one prescription and any supplement, the check is the point. Type the name on the box and Intaq takes it from there.
Families
One organizer, up to three adults and the children's profiles, each person choosing what is shared. Meals and the shopping basket are scored for everyone. For families.
Clinics and brands
Screen a patient's list without storing anything that identifies them, or check a formulation against the same standard a consumer sees. For practitioners, for brands.
