Vasati vaburitsa zvabuda, Consumer Reports vakabatana nevagadziri vezvigadzirwa makumi maviri nenhatu. Makambani manomwe haana kupindura (BSN, Dymatize, Jocko Fuel, Muscle Milk, Owyn, PlantFusion uye Transparent Labs), Optimum Nutrition aramba kutaura uye Huel haana kupindura nezvehuwandu hwecadmium.
Pakati peavo vakapindura, vakati wandei vakasimbirira kuti Mutobvu chinhu chakasikwa chinonetsa kudzivisa, kunyanya mumiti-based formulas. Makambani masere — Equip Foods, Garden of Life, KOS, Momentous, Muscle Meds, Muscle Tech, Orgain, neVega — vakashuma kuti vanoedza zvinhu uye zvigadzirwa zvakapedzwa zvesimbi inorema.
Huel yakavimbiswa kuisa zvinhu zvayo zvakasvibirira "kuomesesa test" uye kuti zvigadzirwa zvayo zvinoramba zviri mukati mematanho akatarwa nesangano rakazvimirira reNSF. Naked Nutrition, kune chikamu chayo, yakasimbisa kuti inotenga vatengesi vane magwaro ebvunzo uye akakumbira bvunzo dzechitatu kune yayo Mass Gainer zvichitevera zvakawanikwa.
Kubva kuAbbott (Ensure) vakaratidza kuti mazinga akawanikwa neCR ndeaya yakaderera kune chirimwa chigadzirwa uye kuti mutengi anogona kuvimba nekuchengeteka kwayo; Quest yakaramba ichiti data rinoratidza izvozvo zvirongwa zvavo zvekuchengetedza chikafu zvinoshandaBindu reHupenyu uye Orgain vakadzivirira kushandiswa kwemazuva ese kwevanonongedza, vachitaura kuti miganhu yavo yemukati inotevera FDA, EPA, WHO, uye EFSA nhungamiro.
Vega yakataura kuti inoenderana nemirairo yese inoshanda uye yakatsanangura se "zvisingawirirani" cadmium mhedzisiro inopesana neayo periodic bvunzo. Iyo kambani inoshanda pasi Chirevo 65 chibvumirano chemitemo yeCalifornia - zvibvumirano zvinosunga zviri pamutemo - uye yakabhadhara mari inosvika madhora mazana matatu nemakumi matatu nematanhatu ekugadzirisa 2013 uye 2018 zvichemo zvesimbi inorema zviri kutengeswa pasina yambiro yakakwana, pasina kubvuma mhosva.

Momentous akataurirana a kuongororwa kwakadzama kwemafomula uye zvigadzirwaZvigadzirwa zvakaongororwa neCR zvino zvakamiswa, kunyangwe zvakaverengerwa nekuti izvi zvinowedzera zvine hupenyu hurefu hwesherufu uye zvinogona kuramba zviri mumapantries.
Kana ari mazita akazvimirira, Momentous neVega vakati vanosangana nezviyero zve NSF: 10 micrograms / zuva yekutungamirira uye inorganic arsenic, uye 4,1 micrograms / zuva ye cadmium. Muscle Meds yakaratidza kuti inosimbisa kutevedzera 10 µg yemutobvu pakushumiraVaNaked Nutrition vakati vari mushishi rekupihwa chitupa cheNSF.

Mazhinji masangano epasi rose Havana kugadza miganhu chaiyo yomutobvu mumaprotein poda kana zvekudya zvinowedzera. EPA haidzore lead muchikafu, asi inochengetedza a chiito chechikamu che10 ppb mumvura yepombi (Kuenzanisa, CR yakaona 61 uye 15 ppb mune zvimwe Bindu reHupenyu uye Orgain zvigadzirwa, zvichiteerana.)
Iyo FDA haina kumisa matanho ekuita nokuda kwomutobvu muupfu kana kuti ma<em>protein anozunungusa, uye WHO inosimbisa kuti hapana kudyiwa kwevhiki nevhiki kwomutobvu kunogona kurangarirwa kuva kwakakotsekana.
