Copper-Quercetin Complexes: Methods of Study, Relevance to Cell Death Pathways, Therapeutic Applications

    April 2025 in “ Biomedicine & Pharmacotherapy ”

    TLDR Copper-quercetin complexes could be effective in treating cancer, infections, and promoting bone healing.
    Copper-quercetin (CuQ) complexes show significant potential in therapeutic applications, particularly in cancer treatment, bone healing, skin diseases, and androgenic alopecia. These complexes are more effective antioxidants than quercetin alone and can induce DNA damage, which is beneficial for targeting tumor cells. In androgenic alopecia, a combination of copper, zinc, and quercetin has shown promise in mouse models by inhibiting dihydrotestosterone (DHT), reducing inflammation, and promoting hair follicle stem cell activation. CuQ complexes also enhance osteogenesis and angiogenesis, making them useful in bone engineering and wound healing. Innovative delivery methods, such as nanoparticles and microneedles, improve their stability and bioavailability. However, further research is needed to fully understand their therapeutic potential and safety.

      The user is considering whether to continue their hair loss treatment, which includes finasteride, minoxidil spray, keto shampoo, and dermarolling. Suggestions include increasing minoxidil application, adding multivitamins, improving sleep, and possibly switching to dutasteride, while the consensus is to keep going with the treatment.

      community what do you think about Ell-Cranell + Quercetin

      in Treatment  7 upvotes 2 years ago
      The post discusses the use of El-Cranell, which contains Alfatradiol, and Quercetin as a treatment for hair loss. The user is seeking recommendations on the amount of Quercetin to add to the solution. The conclusion of the document is that Quercetin has been shown to stimulate hair growth and inhibit DHT, and combining it with zinc/copper may have a synergistic effect.

      community Copper Literally Saved My Life (and My Baldness)

      Oral copper supplementation significantly improved hair regrowth for someone who experienced severe hair loss after stopping minoxidil, suggesting copper deficiency might hinder minoxidil's effectiveness. The user now only takes copper and occasionally uses microneedling, recommending others to try copper if minoxidil alone isn't effective.

      DIM is suggested to help with estrogen metabolism for those on finasteride or dutasteride, potentially reversing side effects like fat gain and mood changes. Some users doubt its effectiveness, recommending lifestyle changes or consulting a doctor instead.
