"Collagen ba shi da amfani ga tsokoki"

Ka taba ganin irin wannan sakon a shafukan intanet. Gaskiya ne collagen ba cikakken protein ba ne; yana ƙunshe da ƙarancin sinadaran amino da ake bukata domin haɓaka tsoka. Amma wani gwaji na bazuwar, da aka yi double‑blind, a kan manya maza masu fama da sarcopenia (ƙarancin ƙashi da tabarbarewar tsoka) ya ƙara zamewa wannan batu ɗan rikitarwa. Maza da suka yi ɗaga nauyi kuma suka sha gram 15 na collagen peptides a rana sun samu kashi 45 % ƙarin ƙashin ƙashi mara kitse fiye da rukunin placebo, kuma ƙarfin ƙafafunsu ya ninka fiye da ninki biyu.

Kafin ka yanke shawarar siyan samfurin, ga muhimman abubuwan da ya kamata ka sani.

Gwajin: Waɗanda aka yi, Menene, da Tsawon Lokaci

Binciken da aka wallafa a British Journal of Nutrition a shekarar 2015, da Zdzieblik da abokan aikinsa, ya haɗa maza 53 masu shekaru matsakaicin 72.2, duka suna da sarcopenia mataki I ko II.

Duk mahalarta sun yi aikin horon ƙarfi tsawon makonni 12, sau uku a mako. Bambanci kawai shi ne abin da suka sha bayan kowane motsa jiki:

• Rukunin magani: gram 15 a rana na collagen peptides
• Rukunin placebo: silika – wani abu da ba shi da tasiri a jiki

Masu binciken sun auna ƙashin ƙashi mara kitse, yawan kitse, da ƙarin ƙashin ƙashi ta hanyar DXA scans. Suka kuma gwada ƙarfin quadriceps da ƙwarewar motsi ta hanyar gwajin daidaita kafafu guda ɗaya.

Sakamako: Kowa ya inganta, amma Collagen ya fi samun ci gaba

Horon da kansa ya haifar da ƙaruwa a dukkan rukuni. Duk rukunoni sun samu ƙaruwar ƙashin ƙashi mara kitse, yawan ƙashi, ƙarfin ƙafafu, da ƙwarewar motsi, kuma suka rage kitse. Sai dai rukunin collagen ya fi haɓaka a kan manyan abubuwa uku (duk P < 0.05):

Sakamako	Collagen	Placebo
Ƙashin ƙashi mara kitse	+4.2 kg	+2.9 kg
Ƙarfin quadriceps	+16.5 Nm	+7.3 Nm
Kitse	−5.4 kg	−3.5 kg

Lissafin da aka yi ya nuna cewa bambancin 4.2 kg da 2.9 kg ya ba da kusan 45 % ƙarin ƙashin ƙashi mara kitse. Ƙarfin quadriceps ya ninka da kusan 2.3 sau, kuma raguwar kitse ma ta fi na rukunin placebo.

Me zai sa Collagen Peptides su taimaka?

Har yanzu ba a san ainihin hanyar aiki ba, kuma gwajin bai zo da ƙayyadaddun hujjoji ba. Akwai wasu zato da ake nazari:

• Samar da amino acids. Collagen yana da yawa a glycine, proline, da arginine. Waɗannan suna taka muhimmiyar rawa a haɗin ƙashi, ƙirƙirar creatine, da hanyoyin nitric oxide. Ko suna da tasiri kai tsaye a haɓaka tsoka a manya, wannan na buƙatar ƙarin bincike.
• Peptides masu aiki. Collagen da aka ƙwaƙwalta yana fitar da ƙananan peptides (misali, hydroxyproline‑containing fragments) da ke wucewa narkewa su shiga jini, inda za su iya ba da saƙon ga ƙwayoyin tsoka da ƙashi. Shaidar da ke akwai a yanzu ba ta da ƙarfi sosai.
• Ƙarfafa haɗin ƙashi (tendon) da matrix extracellular. Ingantaccen goyon baya a wannan ɓangare na iya ba da damar ɗaga nauyi da watsa ƙarfi yadda ya kamata. Wannan ra'ayi na da ƙarfi amma har yanzu yana cikin gwaji.
• Kawai ƙarin protein. Manya da yawa ba su cinye isasshen protein ba a kullum. Ƙara gram 15 na protein (ko a wannan yanayin collagen) na iya taimaka wa ƙara ƙarfin tsoka ba tare da la’akari da asalinsa ba.

Waɗannan duk zato ne, ba hujjoji na ƙarshe ba.

1. Placebo ba a daidaita da protein ba

Silika ba ta ƙunshi amino acids ko protein. Don haka ba za a iya raba “collagen na da wani abu na musamman” da “ƙarin protein ke taimakawa” ba. Idan aka kwatanta da whey ko wani protein mai leucine mai yawa, za a iya samun bambanci, amma wannan gwajin bai yi hakan ba.

2. Dangantaka da masana’anta

Wani daga marubutan yana da alaƙa da Collagen Research Institute, kuma samfurin da aka yi amfani da shi an samo shi daga mai sayar da collagen. Wannan ba ya kawar da sahihancin sakamakon, amma yana nuni da buƙatar ƙarin gwaje‑gwaje daga masu zaman kansu.

3. Ƙungiyar mutane ba ta da faɗi

Masu halarta su ne manya maza da ke da sarcopenia kawai. Ba za a iya ɗauka wannan sakamakon zai yi aiki ga mata, matasa, ko manya masu lafiya da ke samun isasshen protein ba.

4. Collagen ba cikakken protein ba ne

Yana da ƙarancin leucine, amino acid da ake danganta da haɓakar tsoka, kuma ba shi da tryptophan. Wannan ne tushen batun “ba shi da amfani ga tsokoki”, kuma shine dalilin da ya sa wannan sakamakon ya zama abin mamaki.

5. Girman tasiri ya yi babba

Ƙaruwa da wasu kilogram na ƙashin ƙashi mara kitse a cikin makonni 12, tare da raguwar kitse a rukunin placebo, ya fi yawan abin da mutane da yawa ke tsammani. Rukunin ya ƙunshi ƙanana mutane, kuma auna DXA na iya canzawa da ruwan jiki da wasu abubuwa. Mujallar ta kuma buga erratum a 2025 da gyara a 2016; don haka yana da kyau a karanta takardar asali da gyaranta maimakon dogaro da lambobi kawai.

Abubuwan da Za a Iya Amfani da su

Idan kana tunanin amfani da collagen peptides don ƙara tsoka, ga abin da hujjojin ke gaya maka:

• Matsakaicin da aka gwada: gram 15 a rana, a sha bayan horon ƙarfi.
• Horon shine mafi mahimmanci. Rukunin placebo ma ya sami ƙaruwa a tsoka da ƙarfin jiki. Collagen ƙari ne ga ɗaga nauyi, ba madadin horon ba.
• Kada ka maye gurbinsa da protein cikakke. Tabbatar abincinka ya ƙunshi isasshen protein mai kyau (mai leucine) daga nama, madara, ƙwai, ko whey. Collagen zai iya zama ƙarin, ba maye gurbinsa ba.
• Waɗanda suka fi dacewa: manya maza masu shekaru 60 + da ke cikin horon ɗaga nauyi, musamman wadanda ke cikin haɗarin sarcopenia ko ba su samun isasshen protein a abinci.
• Waɗanda ba za su iya sa ran mu'ujiza ba: mutane marasa motsa jiki ko waɗanda ba su yi horon ƙarfi ba. Babu hujja a cikin wannan gwaji da ke nuna cewa collagen kaɗai zai gina tsoka.
• Ka tuntuɓi likita idan kana da matsalar koda, cuta, alerji (collagen yawanci daga shanu, alade, ko kifi), ko kuma kana kan wani tsarin cin abinci na musamman.

Gaba ɗaya

Meme ɗin “collagen ba shi da amfani ga tsokoki” ya yi sauƙi sosai. A gwajin da aka ambata, manya maza masu sarcopenia da suka sha gram 15 na collagen peptides su ne suka ƙara ƙashin ƙashi mara kitse da ƙarfin ƙafafunsu fiye da waɗanda suka sha silika. Amma tsarin gwajin ya bar tambaya: shin collagen na da siffofin musamman ko kuwa kawai ƙara protein ne ga abincin da ba ya wadatuwa?
