Recently, I know about antioxidants, practically everything and even more. The reason for this was the oncological diagnosis of my loved one. It was not possible to operate the tumor due to concomitant cardiovascular problems, and a consultation of physicians decided to use radiation therapy, and while preparing for hospitalization (tests and other examinations) it was strongly recommended to start taking antioxidants. The pharmacist in the pharmacy reacted to the word “antioxidant” by a penny ascorbic. It seemed to me then too simple treatment and I studied the question thoroughly. It turned out that millions of healthy cells die every day in our body, because they are literally devoured by free radicals. Organ (all different), lost a critical number of healthy cells stops working normally, severe pathologies develop which lead to a malfunction in the work of other interrelated bodies. The body literally does not know how to regenerate organs or rid itself of the products of decay of dead cells? And the main thing for all this requires a huge amount of vitamins and trace elements in the right forms and proportions, and who have they? In the case of radiotherapy, the amount of free radicals increases in thousands, and maybe millions of times. And this is exactly the most destructive effects of irradiation for the body. Those. radioactive rays, killing a tumor, simultaneously create an army of “rippers” that destroy everything alive and necessary. And they can be countered only by antioxidants, which literally disarm free radicals, enabling the body to concentrate entirely on combating the tumor. According to numerous medical sources, quercetin is one of the most powerful natural antioxidants, and in the fight against oncology – simply the best! It is quercetin that has the ability to activate the p53 gene in cancer cells, which causes them to self-destruct. The search for quercetin, to my great happiness, brought me to Foodpharmacy Blog. Quercetin and Bromelain from Doctor’s Best in a dosage of 3 grams per day did their job perfectly well! The course of irradiation passed without any unpleasant sensations and complications. The blood counts were not just normal, but even better than before the treatment, doctors were very perplexed about this.

We plan to take quercetin, if not all of life, then for a few more years exactly, and already with the whole family. Moreover, the visual results after 2 months of admission already have all.

Probably now, after a huge amount of useless and expensive drugs that doctors prescribed, and drugs that were bought by rating reviews – Quercetin is all or almost all that my vessels need after suffering terrible vasculitis associated with an autoimmune disease.

The time of adoption depends on the goal: If there is more to restore the walls, then in the morning during breakfast, But if it comes to dissolving cholesterol plaques and viral films, then of course in the evening before going to bed. And watch your condition while taking Badi! Track reactions, adjust doses and educate yourself! Be able to distinguish truthful reviews from laudatory chants in the name of referral codes! And do not despair. The body is able to recover. I wish you health and successful discoveries on Ay Herb!

Absolutely in delight! What I have not tried in the last 10 years of fighting the spring allergy – suprastin, klaritin, cetrin, even hydrogen peroxide and activated charcoal saws, washed the nose with a non-itch, but it all gave a slight non-long-term effect! Best of all, these miracle cracks worked! Began to drink at the end of May, at night 2 capsules – and that’s it! A week later, the effect was enough for the whole day, no tear, irritated eyes and nose, no dry cough, no nocturnal breathing spasms! Everything was forgotten like a terrible dream!
