1 Kev Taw Qhia

Lutein hmoov, ib hom carotenoid, alias carotene, phytolutein, ribosome, marigold paj caij thiab phytolutein, thiab lwm yam. Lus Askiv lub npe yog Lutein, uas yog ib yam khoom tseem ceeb uas ua rau macular pigment. Lutein hmoov tsis muaj peev xwm ua rau muaj kev pheej hmoo ntawm macular degeneration, thiab tuaj yeem ua rau muaj ntau yam kab mob ntawm lub qhov muag thiab qhov muag tsis zoo.

Lutein hmoov tsis tuaj yeem tsim los ntawm nws tus kheej, tab sis tuaj yeem tau txais los ntawm cov khoom noj thiab tshuaj ntxiv. Lutein tuaj yeem nqus tau thaum noj zaub thiab txiv hmab txiv ntoo, tab sis qhov nqus thiab siv feem ntau yog tsawg. Cov tshuaj ntxiv tuaj yeem noj yog tias tsis muaj lutein.

2 Muaj nuj nqi

2.1. Tiv thaiv retina thiab ua kom pom tseeb

Lutein hmoov yog ib qho antioxidant zoo, uas tuaj yeem zam oxidative puas tsuaj rau lub retina thaum nws nqus lub teeb; Nws tuaj yeem tiv thaiv capillaries ntawm lub qhov muag thiab tswj cov ntshav zoo.

2.2. Txhim kho qhov muag pom

Lutein hmoov yog ib qho muaj zog antioxidant uas tuaj yeem pab lim tawm lub teeb xiav, txo cov chromatic aberration, thiab ua kom pom tseeb dua.

2.3. Tiv thaiv glaucoma

Lutein hmoov tuaj yeem txo qhov kev siv oxidative siv ntawm lub qhov muag cov proteins, thiab qhov ntau dua qhov kev noj, qhov tshwm sim ntawm glaucoma.

2.4. ncua qhov tshwm sim ntawm cataracts

Lutein hmoov yog tib qho carotenoid uas muaj nyob hauv cov muaju, uas tuaj yeem txhim kho lub peev xwm antioxidant ntawm cov muaju, tiv thaiv kev puas tsuaj ntawm tshav ntuj thiab dawb radicals, thiab ncua lossis tiv thaiv qhov tshwm sim ntawm cataracts.

2.5. Tiv thaiv cov sequelae ntawm siab myopia

Cov myopia siab yog nquag ua rau cov retinal detachment, hydrops, floaters, thiab lwm yam, thiab tseem ua rau qhov muag tsis pom kev mus tas li. Ntxiv cov lutein txaus tuaj yeem ua rau lub qhov muag muaj zaub mov txaus, uas tuaj yeem txo qhov tshwm sim ntawm qhov txhab.

2.6. Txo cov macular degeneration thiab qhov txhab

Macular degeneration yog qhov ua rau dig muag hauv cov neeg laus. Kev ntsuam xyuas tau pom tias lutein tuaj yeem pab cov neeg mob uas muaj hnub nyoog ntsig txog macular degeneration los txhim kho qhov muag.

3 Daim ntawv thov

Nws tuaj yeem siv los ua tsiaj pub additive rau pub, zaub mov xim tus neeg saib xyuas thiab noj qab haus huv cov zaub mov mos capsule ntawm cov zaub mov.
