Our cells are constantly under attack by naturally occurring and ambient-induced reactive molecules, known as free radicals. Over time, free radicals damage our cells by causing oxidative stress, this process accelerates ageing and brings on a range of other age-associated health problems. Free radicals play a role in the promotion of inflammatory and cardiovascular diseases, cancer, and strokes. For this reason, good quality antioxidants are an essential supplement in the fight against free radicals. With its potent antioxidative properties, Sfera Bio Nutrition Quercetin Complex helps counteract these free radicals. Sfera Bio Nutrition Quercetin Complex has anti-inflammatory, anti-allergic, antioxidant, immuno-modulative, and cardioprotective properties. It aids in the treatment of vascular insufficiency, diabetes, allergic rhinitis, asthma, and neuroprotection and cognition issues. 

With added nettle and bromelain for superior absorption and anti-inflammatory effects, Sfera Bio Nutrition Quercetin Complex inhibits histamine release, making it helpful in the treatment of allergies and reducing sneezing caused by allergic rhinitis. Because free radicals can activate transcription factors that generate pro-inflammatory cytokines, Sfera Bio Nutrition Quercetin Complex effectively treats inflammation through its free radical scavenging properties. Conditions such as myalgia, constant body pain, prostatitis, and gastrointestinal disorders can be eased with the regular intake of Sfera Bio Nutrition Quercetin Complex. This supplement is also useful in treating cholesterol because it prevents the oxidation of low-density lipoproteins which play a role in forming plaque and clots associated with cardiovascular disease. To ease the symptoms of type 2 diabetes neuropathy, Sfera Bio Nutrition Quercetin Complex decreases numbness, irritation, and joint pain.

How it works

Sfera Quercetin Complex contains added nettle and bromelain for superior absorption and anti-inflammatory effects. It assists with the relief of inflammation, osteoarthritis and improves joint health.


Quercetin is effective at inhibiting the release of histamine by stabilizing the membranes of mast cells.  The intake of quercetin supplements has proven effective at reducing sneezing in allergic rhinitis conditions.


Inflammation is another condition which can be reduced by free radical scavenging properties of quercetin. Free radicals can activate transcription factors that generate pro-inflammatory cytokines, which are often found elevated in patients that suffer from chronic inflammatory conditions such as prostatitis, constant body pain, myalgia, insomnia and gastrointestinal disorders. It could also potentially prove useful to cells involved in allergic inflammation.


Quercetin has shown the ability to prevent the oxidation of low-density lipoproteins LDL by reacting itself with free radicals.  The oxidation of LDL result in the formation of clots and plaques which cause cardiovascular disease.


Quercetin has shown to help decrease the seriousness of numbness, jolting pain and irritation for patients with type 2 diabetes neuropathy.
