Relieves headaches
Recommend!!! I have been taking quercetin on my doctor’s advice for 2-3 months as it acts as a "cleanser" for blood vessels and improves blood circulation. Notably, quercetin offers anti-inflammatory effects, benefiting conditions like heart disease, blood vessel issues, allergies, chronic fatigue, as well as combating infectious and autoimmune diseases. It effectively alleviates headaches caused by spasms in the brain's vessels, enhances my overall emotional state, and restores my energy and activity levels.

Caused headaches daily
This product gave me significant headaches. After taking it for a week, I experienced headaches every day, despite not usually getting them. I stopped for three days without headaches, but upon starting again, I faced daily headaches. I stopped again, and I haven’t had any headaches since.

Quercetin truly aids in alleviating flu and COVID symptoms, especially when combined with Zinc. It effectively removes severe headaches, as well as body aches.

Headaches gone
Excellent! This is a very beneficial supplement. I've noticed visible signs of improvement: my skin feels smoother, and I used to suffer from headaches, but now they have vanished.
