  • Yes, we are taking a loss at this amount. Take advantage while we gain traction. We have been strictly selling to clinicians and homeopaths for years and we now bring Research Labs High Absorption Quercsalis Quercetin w/ Bromelain to this marketplace.
  • WHY YOU NEED OUR FORMULA - Quercetin is absorbed very poorly by itself meaning you are flushing the very expensive ingredients down the drain. Our proprietary formula and manufacturing process of Quercsalis Quercetin w/ Bromelain significantly enhances the bioavailability or amount your body can use.
  • The histamines that are generated by cells in response to allergic and inflammatory reactions are decreased by the anti inflammatory effects of quercetin. Subsequently, assisting in reducing inflammation-related aches and discomfort.
  • HEALTHY CARDIOVASCULAR & IMMUNE SYSTEM FUNCTION: Quercetin, a naturally occurring free radical scavenger, helps a balanced immune system. Quercetin has been shown in laboratory experiments to support healthy respiratory function. Quercetin supports cardiovascular health via its role in the inhibition of LDL oxidation
  • Research Labs' owner believed in creating the highest quality supplements everyone could afford. We take no shortcuts and use no fillers to create the highest quality vitamins for the best price you can find.

After weeks of use, the difference in how my body processes this supplement is genuinely noticeable. Most quercetin products suffer from poor absorption, which feels like a waste of money, but Research Labs addresses this directly with their Quercsalis high-absorption formula. By combining quercetin with bromelain, they’ve created a way to actually utilize the nutrients rather than just flushing them away. I’ve found it particularly helpful for managing the discomfort associated with inflammatory responses and supporting my respiratory health. It is rare to find a professional-grade formula that was previously exclusive to clinicians now available at such an accessible price point. Since they avoid unnecessary fillers, you are getting a clean, potent antioxidant that supports both cardiovascular health and immune function without any extra fluff.

Just think what this means for the whole body’s ability to heal and repair.
  • 100% Icelandic Astaxanthin sourced from Haematococcus pluvialis micro-algae so you know it’s clean and pure. Manufactured in a GMP certified facility in the USA. Never any herbicides, pesticides, GMOs or industrial pollutants.
  • Nutrient rich powerful antioxidant often called “the king of carotenoids” helps reduce oxidation which is responsible for the majority of internal swelling, redness/flammation in our bodies.
  • Research Labs Astaxanthin may help with eye, heart, joint, complex cognitive problems and "cells that quickly grow incorrectly."

It is easy to feel cynical about antioxidant claims that sound too good to be true, but Research Labs is actually backing up its potency with serious science. This 12mg formula uses 100% Icelandic Astaxanthin sourced from Haematococcus pluvialis micro-algae, making it a powerhouse that significantly outperforms Vitamin E and Vitamin C in antioxidant strength. I was particularly impressed by the inclusion of organic coconut oil, which is a smart move for enhancing absorption of this fat-soluble nutrient. By targeting internal oxidation, this supplement aims to support everything from eye and heart health to joint mobility and cognitive function. It feels like a premium, clean option for anyone looking to manage inflammation and cellular repair without the heavy price tag usually found in high-end wellness aisles.

Damaged cells and DNA lead to decreased ability to burn fat leading to many problems, cardio issues, fatigue, aging-related muscle loss, cognitive decline, eyesight and hearing, shorter lifespan.

  • ENCOURAGE HEALTHY IMMUNE FUNCTION - Quercetin and vitamin C both promote immune health: in a randomized clinical trial, quercetin encouraged a healthy immune response in physically fit older adults—and we all know how much immune challenges want a taste of 1000 mg of vitamin C.
  • PROMOTE OVERALL HEALTH – Quercetin helps promote a healthy inflammatory response. Vitamin C encourages healthy iron uptake as well as collagen production. Plus, what vitamin Cdoes for your body is complemented by quercetin. In fact, vitamin C and bioflavonoids are often present together in healthy foods such as fruits and vegetables, and citrus fruit.

Most people assume that swallowing more quercetin is the key to better health, but without the right delivery system, you are mostly just wasting your money. This formula from Life Extension solves that specific problem by using a phytosome wrap that makes the quercetin fifty times more bioavailable than the standard versions you find on most shelves. It pairs that advanced absorption with a robust dose of Vitamin C to support your immune system, collagen production, and iron uptake. It feels like a smarter way to mimic the natural synergy found in whole citrus fruits. Just a heads-up: because of the quality of these ingredients, you should make sure you are home for delivery to avoid any heat-related damage during transit.

  • Yes, we are taking a loss at this amount. Take advantage while we gain traction. We have been strictly selling to clinicians and homeopaths for years and we now bring Research Labs High Absorption Quercsalis Quercetin w/ Bromelain to this marketplace.
  • WHY YOU NEED OUR FORMULA - Quercetin is absorbed very poorly by itself meaning you are flushing the very expensive ingredients down the drain. Our proprietary formula and manufacturing process of Quercsalis Quercetin w/ Bromelain significantly enhances the bioavailability or amount your body can use.
  • The histamines that are generated by cells in response to allergic and inflammatory reactions are decreased by the anti inflammatory effects of quercetin. Subsequently, assisting in reducing inflammation-related aches and discomfort.
  • HEALTHY CARDIOVASCULAR & IMMUNE SYSTEM FUNCTION: Quercetin, a naturally occurring free radical scavenger, helps a balanced immune system. Quercetin has been shown in laboratory experiments to support healthy respiratory function. Quercetin supports cardiovascular health via its role in the inhibition of LDL oxidation

After weeks of use, the difference in how my body processes this supplement is genuinely noticeable. Most quercetin products suffer from poor absorption, which feels like a waste of money, but Research Labs addresses this directly with their Quercsalis high-absorption formula. By combining quercetin with bromelain, they’ve created a way to actually utilize the nutrients rather than just flushing them away. I’ve found it particularly helpful for managing the discomfort associated with inflammatory responses and supporting my respiratory health. It is rare to find a professional-grade formula that was previously exclusive to clinicians now available at such an accessible price point. Since they avoid unnecessary fillers, you are getting a clean, potent antioxidant that supports both cardiovascular health and immune function without any extra fluff.

Solaray Mega Quercetin stands out because it pairs a high-potency 600 mg dose with bromelain and bioflavonoids for superior absorption. I found the formula particularly impressive because it doesn't just stop at quercetin. The addition of Vitamin C and AMPK activators makes it a comprehensive tool for supporting your circulatory, respiratory, and immune systems. It is a smart choice for anyone needing sinus relief or cellular support, especially since the vegan VegCaps are easy to swallow. I also really respect the brand's commitment to the planet, using 100% PCR bottles made from ocean and landfill plastics. It feels like a high-quality, conscientious supplement that actually delivers on its promise of targeted wellness support.
