The bloating was one thing, but every morning I felt like I have something stuck in my throat that I desperately want to caugh out, but couldn’t. ChatGpt told me to get Quercitin and Vitamin C. I’ve heard about this brand Thorne that athletes use so even tho more expensive than other brands - I gave it a try. Long and behold the sensation in the throat IS GONE. I don’t know the histamine levels, but it is obvious this works Review: Life Changing? - I'm a long-perm consumer of anti-depressant and anti-enxiety meds. This Thorne product appears to have have given me the boost that prescription meds cannot match. Such has been the positive change in the six weeks since I began taking it, I am reluctant to put it all down to Quercetin, but I haven't had a single bad day since starting them. Before this, I rarely had a good day. I will update in a few months. ## Features - Optimised Bioavailability: Featuring quercetin phytosome (phospholipid complex from sunflower), shown to be up to 20 times more bioavailable than standard quercetin extract - High-Purity Formula: Delivers 250 mg quercetin phytosome per capsule with minimal, clean-label excipients and no gluten, soy, dairy, shellfish, or fish - Trusted Ingredient Sourcing: Contains plant-based flavonoids, a class of compounds naturally found in fruits, vegetables, and tea - Flexible Use: Take 1 capsule two to three times daily with meals or as recommended by your health-care practitioner - Science-Backed & GMP Certified: Every Thorne supplement is crafted using evidence-based research, GMP-certified manufacturing, third-party testing, and with a commitment to product purity and safety, supporting individual wellbeing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0797DQTVZ | | Age Range Description | Adult | | Allergen Information | Contains: Gluten Free | | Benefits | Immune Support | | Best Sellers Rank | 18,759 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 12 in Quercetin Antioxidant Supplements | | Brand | THORNE | | Brand Name | THORNE | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 2,248 Reviews | | Diet Type | Gluten Free | | Dosage Form | Capsule | | Flavour | Apple | | Item Dimensions | 5.3 x 5.3 x 9.4 centimetres | | Item Form | Capsule | | Item Weight | 59 g | | Item form | Capsule | | Item weight | 59 g | | Manufacturer | Thorne Research | | Manufacturer Part Number | SB335 | | Model Number | SB335 | | Number of Items | 1 | | Primary Supplement Type | B-Complex | | Primary supplement type | B-Complex | | Specific Uses For Product | Cellular Health,Immune,Immune Support,Inflammatory Response | | UPC | 693749004356 | | Unit Count | 60.00 count | | Unit count | 60.00 count | ## Product Details - **Age range (description):** Adult - **Brand:** THORNE - **Diet type:** Gluten Free - **Flavour:** Apple - **Item dimensions L x W x H:** 5.3 x 5.3 x 9.4 centimetres - **Item form:** Capsule - **Item weight:** 59 g - **Primary supplement type:** B-Complex - **Product benefits:** Immune Support - **Unit count:** 60.00 count ## Images ![Thorne Quercetin Phytosome, 60 Capsules | Advanced Phytosome Complex for Superior Absorption, Flavonoid Formula - Image 1](https://m.media-amazon.com/images/I/71aVcjDhxaL.jpg) ## Questions & Answers **Q: What makes Thorne supplements high quality?** A: Thorne produces high-quality supplements through rigorous testing, well-researched ingredient sourcing, and strict manufacturing standards.
