Quercetin is a much researched and respected flavanoid. Vitamin B (pantothenic acid) helps convert food into energy and is essential for the normal functioning of the adrenal glands. Bromelain is a natural extract from pineapple stem.


New & Improved, this supplement now also includes the accessory elements, nettle, chamomile, pine bark and acerola in addition to the quecertin and vitamin B5. These ingredients combine to create an ideal formula for all seasons, especially the Spring when pollen is most prevalent. Vitamin B5 (pantothenic acid) supports energy production, reducing tiredness and fatigue, and aids normal mental performance. Quercetin is one of several bioflavonoids (special nutrients found with vitamin C in fruit and vegetables) used in popular food supplements. Quercetin consistently demonstrates the greatest activity among the flavonoids studied, with many plants owing much of their activity to their high quercetin content.

Quercetin is great for my hay-fever headaches

I have been using this product for a few years. It’s great. After a couple of days it takes away my crippling hay fever headaches. Highly recommended it.

Viridian Quercetin

Very good


I have autoimmune conditions and take a number of Viridian supplements. I take the Quercetin B5 Plus every day as it really helps maintain mental alertness and supports energy levels.
