Liposomal Vitamin C Powder: Vim Li Cas Liposomal Beats Ordinary Vitamin C

Vitamin C yog ib qho ntawm cov khoom siv dav siv hauv ntiaj teb, khoom plig rau nws lub luag haujlwm hauv kev tiv thaiv kab mob, collagen synthesis, thiab tiv thaiv antioxidant [4]. Txawm li cas los xij, ascorbic acid yooj yooj yim - cov hmoov los yog ntsiav tshuaj daim ntawv feem ntau cov neeg loj hlob nrog - muaj ib tug zoo-cov ntaub ntawv tsis muaj zog: lub cev tsuas yog nqus tau ntau npaum li cas ntawm nws nyob rau hauv ib lub sij hawm, thiab ib tug ntau ntawm cov koob tshuaj tsuas yog tso tawm ua ntej nws puas mus txog rau cov hlab ntsha. Qhov no tsis yog ib qho me me inefficiency; nws yog ib qho nyuaj physiological qab nthab ua rau yuav ua li cas vitamin C yog thauj hla lub plab phab ntsa. Kev nkag siab tias lub qab nthab yog tus yuam sij rau kev nkag siab vim li casliposomal vitamin C hmoovtau dhau los ua hom ntawv nyiam rau cov neeg uas xav tau ntau dua los ntawm lawv cov tshuaj ntxiv yam tsis tau nqos cov tshuaj puv tes los yog lees txais qhov rov qab poob qis.

Vim li cas Ordinary Vitamin C hits ib phab ntsa

Vitamin C tsis hla lub plab hnyuv los ntawm tsuas yog diffusing los ntawm nws - nws qhov kev nqus yog nyob ntawm ib qho tshwj xeeb muaj cov protein, thiab qhov kev vam khom yog lub hauv paus ntawm qhov teeb meem:

• Nws cia siab rau ib qho kev thauj mus los.Kev nqus tau ua haujlwm yuav luag tag nrho los ntawm SVCT1 (sodium-dependent vitamin C transporter 1), low-affinity, high-capacity transporter expressed ontestinal epithelial cells [5].
• Nws ua haujlwm zoo tsuas yog ntawm cov zaub mov - qib koob tshuaj.Ntawm kev noj tsawg mus rau nruab nrab - kwv yees li 30 txog 180 mg, qhov nyiaj koj tau txais los ntawm ib daim txiv hmab txiv ntoo - SVCT1 ua haujlwm tau zoo, thiab bioavailability tuaj yeem ncav cuag 70-90% [5].
• Nws saturates ntawm ntxiv - qib koob tshuaj.Vim hais tias SVCT1 yog ib lub pas dej ua ke ntawm cov neeg thauj khoom, nws yuav saturated ib zaug qhov ncauj koob tshuaj dhau roughly 500-1,000 mg. Nyob rau hauv tas li ntawd mus rau lub point, fractional absorption poob sharply, nrog ib co kev ntsuam xyuas qhia qhov tseem ceeb hauv qab no 50% rau ib koob tshuaj tshaj 1 gram [5].
• Ntau milligrams tsis txhais hais tias proportionally absorption.Muab ob npaug rau vitamin C ntsiav tshuaj los ntawm 1,000 mg mus rau 2,000 mg tsis tau muab ob npaug rau tus nqi uas nce mus txog koj cov ntshav - ib feem loj yog sab laug unabsorbed nyob rau hauv lub plab los yog sai sai tshem tawm los ntawm ob lub raum ib zaug plasma qib nce, txij li thaum lub raum reabsorption yog tswj los ntawm tib saturable thauj system [5].
• Qhov no tsis yog tshiab - nws yog ib xyoo caum- qub, zoo -tsim txwv.Cov koob tshuaj- nyob ntawm qab nthab tau lees paub hauv cov ntaub ntawv tshuaj pharmacokinetic txij li xyoo 1970s, thiab nws yog qhov kev sib tw hauv nruab nrab uas cov khoom "tom ntej- tiam" vitamin C yuav tsum tau daws [5].
• Ascorbic acid kuj yog tshuaj tsis yooj yim.Nws oxidizes nkag tau yooj yim thaum raug tshav kub, lub teeb, oxygen, los yog acidic, enzyme -nplua nuj ib puag ncig ntawm lub plab, degrading ua ntej ntau nws tuaj yeem ncav cuag cov hnyuv, qhov twg nqus tau tshwm sim.
• Kev siv tshuaj ntau ntau ua rau GI tsis xis nyob.Unabsorbed ascorbic acid zaum hauv plab nqus dej osmotically - cov txheej txheem tom qab plab hnyuv thiab cov quav xoob uas feem ntau txwv ntau npaum li cas tus qauv vitamin C ib tus neeg tuaj yeem yooj yim noj.

Liposomal Encapsulation hloov qhov sib npaug li cas

Liposomes yog microscopic spherical vesicles ua los ntawm phospholipids - tib cov roj molecules uas ua rau peb cov cell membranes. Thaum cov vitamin C encapsulated hauv cov lipid bilayers, ob yam hloov ib txhij:

• Kev tiv thaiv thaum digestive.Lub plhaub lipid lub cev tiv thaiv cov ascorbic acid los ntawm lub plab acid, digestive enzymes, thiab oxidation, yog li ntau ntawm cov thawj koob tseem muaj sia nyob mus txog thaum nws mus txog qhov nqus ntawm cov hnyuv.

 

• Ib txoj kev sib txawv rau hauv lub cev.Vim tias liposome lub txheej membrane zoo ib yam li cov phospholipid daim nyias nyias ntawm lub plab hnyuv, nws tuaj yeem raug coj los ntawm txoj hauv kev xws li endocytosis lossis transient membrane fusion, thiab ntawm lub sijhawm ntev mucosal retention - txoj kev uas tsis cia siab rau tib lub saturable SVCT1 transporter uas bottlenecks acid [3] ascorb. Qee cov vitamin C kuj tseem tuaj yeem nqus tau cov lymphatically, nrog rau cov khoom noj muaj roj uas nws tau mus nrog, hla ua ntej - dhau kev txwv tag nrho.

Nyob rau hauv qhov tseeb, liposomal encapsulation hloov vitamin C los ntawm cov khoom thauj - txwv cov khoom noj rau hauv ib qho uas coj zoo li cov rog - cov khoom sib xyaw ua ke thaum nqus tau - uas yog vim li cas nws thiaj tuaj yeem dhau lub qab nthab uas npog cov vitamin C zoo tib yam.

Qhov kev sim tshuaj ntsuam xyuas qhov tseeb qhia tau dab tsi

Qhov no tsis yog ib qho kev siv theoretical xwb - nws tau raug sim ncaj qha hauv kev sim tib neeg:

• Ib qho randomized, ob npaug - dig muag, hla - dhau kev sim sib piv 1,000 mg koob tshuaj liposomal vitamin Chmoovmus rau qhov sib npaug ntawm cov tshuaj uas tsis yog- liposomal vitamin C pom kwv yees li 30% nce hauv tag nrho cov ntshav nqus (chaw nyob rau hauv qhov nkhaus, lossis AUC) thiab 30% ntev dua ntawm cov vitamin C siab dua ntsuas ntawm 24 teev. Cov kws tshawb fawb tau txuas qhov kev txhim kho no mus rau liposomes 'me me, nqaim particles - loj faib thiab siab zeta muaj peev xwm - qhov taw qhia ntawm qhov ruaj khov, zoo- tsim lipid plhaub [1].
• Ib qho kev sib cais, ob npaug - dig muag, placebo- tswj tus ntoo khaub lig- dhau mus sim hauv 27 tus neeg laus noj qab haus huv tau muab 500 mg koob tshuaj tau lees paub tias liposomal vitamin C tsim kev nqus ntau dua rau hauv cov ntshav plasma thiab leukocytes (cov qe ntshav dawb uas vam khom vitamin C piv nrog cov tshuaj tiv thaiv kab mob) - thiab tau ua kom ntseeg tau ntau dua li yav dhau los, kev tshawb fawb me me uas tsis muaj cov placebo caj npab lossis qhov muag tsis pom kev [2].
• Ua ntej pharmacokinetic ua haujlwm ntawm cov kua liposomal formulations ntawm tib 1,000 mg koob tshuaj pom bioavailability ze li ntawm 1.8 npaug ntau dua li cov vitamin C, nrog rau kev nqus tau tshwm sim kwv yees li 2.4 npaug sai dua, ncav cuag cov ntshav siab sai dua [1].
• Ib txoj kev tshawb nrhiav kev sib txuam sib luag ntawm liposomal multinutrient blends txuas rau tib lub laj thawj dhau ntawm cov vitamin C ib leeg, pom tias encapsulation kuj tau txhim kho qhov nqus ntawm zinc thiab hlau los ntawm kev tiv thaiv lawv ntawm lub plab degradation, txhawb nqa cov acidic microenvironment uas khaws cov zaub mov soluble, thiab ua rau lawv dhau los ntawm lawv tus kheej saturable ZMT1 thiab zinc transporters (ZMT1) [3].

Vim tias ntau dua ntawm cov koob tshuaj thawj zaug tau nce mus txog ntau dua li qhov ploj hauv plab lossis degraded ua ntej nqus, tsawg dua milligrams yuav tsum tau ua kom tiav cov ntshav muaj txiaj ntsig - uas kuj yog ib feem ntawm vim li cas liposomal cov qauv yuav ua rau lub plab zoo dua megadoses ntawm cov ascorbic acid.

Yog vim li cas hmoov, tshwj xeeb

Liposomal vitamin C yog muag raws li cov kua, gel, los yog hmoov, tab sis cov hmoov daim ntawv muaj lub tswv yim tiag tiag, tsis yog ib qho kev lag luam. Liposomes muaj tshuaj lom neeg ruaj khov dua thaum qhuav, vim tias tshem tawm cov dej txwv cov oxidation thiab hydrolysis cov tshuaj tiv thaiv uas maj mam ua rau ob lub plhaub phospholipid thiab cov vitamin C hauv nws thaum lub sij hawm cia. Ib txoj kev tshawb fawb uas siv tshuaj tsuag- ziab kom qhuav los hloov cov kua liposomal ncua mus rau hauv cov hmoov tau lees paub tias cov txheej txheem khaws cia liposomes qhov loj me thiab cov qauv kev ncaj ncees, thiab cov hmoov uas tau khaws cia zoo ib yam zoo dua qhov nqus tau zoo li qhov qub ncua kev kawm [1].

Rau cov neeg siv kawg, uas txhais ua ntau yam zoo:

• Lub neej txee ntev duatsis muaj tub yees, vim tias tsis muaj dej theem rau kev loj hlob microbial lossis lipid oxidation los siv.
• Kev thauj mus los yooj yim dua, tsis muaj kev pheej hmoo ntawm kev xau lossis nchuav.
• Flexible, meej dosing, txij li cov hmoov tuaj yeem ntsuas thiab sib xyaw rau hauv dej, kua txiv hmab txiv ntoo, lossis ib qho smoothie nyob rau hauv ntau npaum li cas suits koj.
• Tsawg preservatives, txij li qhov qhuav, qis - dej- cov khoom lag luam yog qhov ruaj khov dua li cov kua emulsion.
