Frequently asked questions

How is QED different from other brands?

In QED products, each ingredient is selected on the basis of publicly available scientific evidence and standardised for maximum support. We only source ingredients from certified manufacturers and openly share all the research behind our formulations.

Are QED food supplements safe?

All QED supplements are manufactured in the EU in facilities that follow current Good Manufacturing Practice (cGMP) and HACCP quality standards. Final product samples are tested by an independent laboratory to ensure they meet safety and purity standards.

As with all dietary supplements, consult your healthcare professional before use if you are pregnant, breastfeeding or taking medication.

Can I take QED dietary supplements during pregnancy and breastfeeding?

Always consult your healthcare professional before taking any dietary supplements during pregnancy or breastfeeding.
Although our products and their ingredients are safe and of the highest quality, your delicate situation requires the advice of a qualified doctor.

How long does it take to see results?

Individual experiences with QED supplements may vary. Some users report noticing effects of QED Energy within the same day. QED Sleep is often taken as part of a nightly wind-down routine. Benefits of QED NAD Booster may be felt gradually over several weeks with regular use.

Can I take several QED products together?

Yes. Take QED Energy in the morning, QED Sleep in the evening and QED NAD Booster with any meal of the day.

Should QED supplements be taken with food?

While some users report good tolerance when taking QED supplements on an empty stomach, taking them with food may help support absorption and reduce the risk of gastric sensitivity. QED Energy and NAD Booster are best taken with food, while QED Sleep can be taken at bedtime.

Where do the ingredients in QED supplements come from?

All ingredients in QED products are sourced exclusively from EU-based suppliers. This ensures that the quality and integrity of all compounds and extracts are thoroughly tested and comply with strict EU regulations.
