Metabolism boost

I heard that this is the one of the key ingredients for our longevity life cycle so I got it. I don’t have any specific notion after I have this but I believe it is somewhat related to my daily exercise routine which is quite intense for my mid 50th age. I’m taking it every night before bed and I have no issues on getting decent deep sleep.

Immune

I always keep extra of this little beauty around. I have an autoimmune problem so if I get unwell, I end up with lung and chest infections, and this is a lifesaver. Can definitely recommend 👍

Night baking starts when the street is empty and ends when everyone else is waking up. I take this at the beginning of the block so the last trays still get care. I walk out into daylight without feeling emptied. Sleep actually happens when I get home. I’ll keep a tin by the mixer.

Lower Uric Acid 7.4 ➝ 6.3 👍

Studies show that supplementation with quercetin can significantly reduce plasma uric acid concentrations. My young sons happen to have high uric acid level at 7.4 (probably genetic). I experimented by giving them a combination of Tart cherry + quercetin + vitamin C to help lower their uric acid without medication. Tart Cherry & Quercetin works as a xanthine oxidase inhibitor (similar to allopurinol). Vit C helps to increase excretion of uric acid in the urine. Their levels drop from 7.4 to 6.3.

Great Quercetin, 500 mg

500 mg quercetin per capsule potent antioxidant and natural antihistamine. Supports mast cell stabilization, viral immunity, and endothelial protection. Works synergistically with bromelain and zinc in inflammation and seasonal allergy protocols. Quercetin is flavonoid that exist in such products as vegetables, fruits, grains, tea and wine. The main benefits that I found for my health are: boosts my immunity system, works as great antioxidant to reduce my inflammation, eases allergy symptoms, reduces upper respiratory tract infection. I like the quality of ingredients as I am happy with result for my health.

I recommend quercetin because it has scientifically supported benefits: it acts as an antioxidant, helps control inflammation, supports immune function, and may help with seasonal allergies and respiratory comfort

Astaxanthin, a powerful antioxidant, offers benefits for skin (UV protection, wrinkles), eyes (focus, fatigue), heart (cholesterol, blood flow), brain (cognitive health), and immunity, primarily by reducing oxidative stress and inflammation. It supports muscle endurance, aids exercise recovery, and shows potential for liver, joint, and male fertility health, though more extensive human research is needed for some claims

Good Quercetin

Quercetin is very helpful, especially when combined with zinc, to improve immunity. I take it when I feel like I'm getting sick, or recovering from something. Sicknesses these days hit much harder than before (I am healthy and I used to never get sick the way I do now), so quercetin is essential. Now brand is quality and at a pretty good price too.
