Propolis & quercetin

NEW: Propolis extract 10% quercetin

Propolis or bees’ gold

A star product of the hive, propolis is a substance obtained from the salivary secretions of bees and from resins or other elements collected from plants and trees (fir, spruce, birch, etc.). Bees use it to strengthen and protect their hives from bacteria, fungi, or variations in temperature. It also reduces the size of openings in the hive, thus protecting against invaders. In fact, propolis comes from the Greek pro, which means “in front of” or “at the entrance”, and from polis meaning “city”.


Why has propolis amassed a following among food supplement consumers in recent years ?

Propolis has been known for over 3,000 years and its role no longer needs to be explained. Indeed, numerous clinical studies have established its immunostimulatory properties. In addition, consumers are turning towards natural and traditional remedies, with proven effectiveness, as a way of preventing infections. Propolis also provides a targeted response to winter ailments making it the perfect old wives’ cure for the colder months.


Propolis extract >10% quercetin for effective and natural protection

Extracted via a high-quality process that preserves its active ingredients, our propolis naturally contains quercetin, giving it many benefits.

While relatively unknown until recent times, quercetin is attracting increasing interest ! Indeed, numerous studies have been conducted to evaluate its action, particularly on the immune system 1, and its anti-inflammatory potential 2.

Quercetin is considered to be the most active of the flavonoids. It promotes the body’s defences in general 3 and is readily bioavailable 4. Moreover, it is known to be particularly rich in antioxidants 5-6. It traps free radicals, thus slowing down the effects of oxidative stress on the body 7
