Frequently Asked Questions.

A Stryō strip is a thin, dissolving film that you place under your tongue. It delivers active ingredients directly into your bloodstream through the sublingual mucosa, bypassing the digestive system entirely. Each strip is pre-dosed, portable, and dissolves in under 60 seconds.

Place the strip flat under your tongue. Hold it in place for 30–60 seconds while it dissolves — avoid swallowing immediately. You can take it with or without water. Each product page includes specific timing guidance for optimal results.

Stryō strips are free from gluten, soy, dairy, and artificial dyes. They are produced in a GMP-certified facility. Full ingredient lists are available on each product page. If you have a known allergy or sensitivity, review the full ingredients before purchasing.

Sublingual means "under the tongue." It refers to a delivery method where a compound is placed beneath the tongue and absorbed through the sublingual mucosa — the thin, highly vascularized membrane in that area — directly into the bloodstream, bypassing the digestive system.

The sublingual route has been studied in pharmacological literature for decades. Research consistently demonstrates that sublingual delivery achieves higher bioavailability for many compounds compared to conventional oral routes, due to avoidance of hepatic first-pass metabolism. The degree of improvement varies by compound — which is why our formula selection considers which actives benefit most from this delivery pathway.

Yes. Every ingredient in a Stryō strip has been selected for sublingual compatibility — meaning appropriate molecular weight, solubility, and mucosa tolerance. Our formulas are manufactured to GMP standards and tested for purity and potency by independent laboratories.

First-pass metabolism (or hepatic first-pass effect) refers to the process by which the liver breaks down substances absorbed from the gastrointestinal tract before they reach systemic circulation. For many active compounds, this significantly reduces the amount that ultimately reaches the bloodstream. Sublingual delivery bypasses this process by entering the bloodstream directly through the sublingual mucosa.

These are FDA-regulated structure-function claims. Under FDA guidelines, dietary supplement manufacturers can describe how an ingredient supports a normal bodily function — but cannot claim to diagnose, treat, cure, or prevent diseases. Our language is chosen carefully to describe mechanisms of support accurately while remaining within these regulatory boundaries. For more detail, see our Health Disclaimer.

A proprietary blend lists multiple ingredients under a single combined weight, without disclosing individual doses. This practice makes it impossible for consumers to verify whether active ingredients are present at clinically meaningful levels. We do not use proprietary blends. Every ingredient and every dose is disclosed individually on our Supplement Facts panels.

Yes. Independent laboratory testing for potency, purity, and absence of contaminants is part of our quality protocol. We do not rely solely on manufacturer certificates of analysis — third-party verification is a standard, not an option.

QADR operates as a life sciences holding with multiple entities, including one focused on therapeutic formulation research. Stryō is built on the same scientific discipline — evidence-based ingredient selection, clinical dosing ranges, and verified supply chains — applied to consumer wellness. The key difference is that our starting point is the scientific literature, not the retail shelf.

Glow and Focus strips: morning on an empty stomach. Zen strips: 30–45 minutes before bed. Core strips: morning or pre-workout. Each product page includes specific usage guidance.

We recommend consulting your healthcare provider before using any dietary supplement during pregnancy or while nursing. Your provider can advise based on your individual situation.

For energy and focus formulas, some users notice effects within 30–60 minutes. For beauty and longevity formulas (collagen, NAD+), consistent daily use over 4–8 weeks is typically needed. Consistency matters more than speed.
