Dosage

Take around 500mg of Quercetin per day, with your first or second meal of the day. This dosage has been shown to be safe and effective in humans.

SENESCENT CELLS CLEARANCE – Quercetin can clear dead cells, improving the overall function of the body and acting as a detoxifying agent. Quercetin has shown potent senolytic effects in multiple studies.

ANTI-INFLAMMATORY – Research shows Quercetin helps with inflammation. The presence of senescent cells is linked to inflammaging, the process of increased inflammation that correlates with old age. By clearing out senescent cells Quercetin helps fight inflammation and ageing and is understood to help preserve NAD+ levels.

SUPPORTS CARDIO HEALTH - Quercetin is a natural compound that supports a healthy cardiovascular system.

PACKAGED AND TESTED IN THE UK - All of our products are third party tested by CAMPDEN BRI before encapsulation and packaging in a class 7 pharmaceutical grade, ISO9001 certified facility in the UK.

Something I use consistently

“I started taking Quercetin + Vitamin C during marathon training. After a day, I noticed how my muscle soreness is dramatically less than it used to be. It has now become something I use consistently rather than only when I feel I need additional support.”

Quercetin + Vitamin C

The formulation is simple

“I bought this for its cellular-ageing rationale, but the first practical difference I noticed was the effect on my hay fever, that is now completely manageable. The formulation is simple, and I appreciate having quercetin and vitamin C together.”

Quercetin + Vitamin C

A permanent place in my routine

“I exercise outdoors regularly and wanted additional support for recovery and seasonal comfort. After a couple of days, I could breathe much better. It has earned a permanent place in my routine alongside NMN.”

Quercetin + Vitamin C

That was when I decided to reorder

“I wasn’t expecting to feel anything immediate from quercetin. The benefit became clearer after another brutal leg day. I think my muscle soreness decreased by about 90% (subjective feeling). That was when I decided to reorder.”

Quercetin + Vitamin C Answers

FAQ

Explore the Quercetin and Vitamin C formula and how it fits into your daily supplement routine.

Why do senescent cells stop dividing?

Senescent cells stop dividing as after several proliferation cycles, cells accumulate DNA damage, and this is a precautionary measure to ensure genomic instability does not lead to cancer. That’s why our cells turn into zombie, senescent cells.

Why are there Vitamin C and citrus bioflavonoids in your Quercetin formula?

Vitamin C prevents the oxidation of Quercetin, ensuring that it stays in it’s reduced form, which in turn makes Quercetin more efficient as an antioxidant, while boosting it’s bioavailability. Vitamin C is found in nature in the presence of citrus bioflavonoids, and hence, their addition optimises the efficiency of Vitamin C. The combination of Vitamin C and citrus bioflavonoids boosts the antioxidant capacity of our blend, and this in turn, optimises the effect of Quercetin.

Is your form of Quercetin easily absorbed by the human body?

As explained under the previous question, yes! You may consider increasing the absorption even further by taking your Quercetin with food or something fatty, such as fatty yoghurt or extra virgin olive oil.

How much Quercetin should I take and when?

Take around 500mg of Quercetin per day, with your first or second meal of the day. This dosage has been shown to be safe and effective in humans.

Is Quercetin safe to take by anyone?

In general, Quercetin is considered as safe with little to no side effects observed in human clinical trials. There is no sufficient data in pregnant or breastfeeding women, and therefore it should be avoided by these groups of women. People with kidney disease should also be cautious with Quercetin and always consult with their doctor first before taking Quercetin.
