Linkki kertoo, että yleiset oksidi ja gluconaatti eivät imeydy ollenkaan. Pikolinaattia taas ei tunnu löytyvän mistään. Entä kuinka hyvä aminohappokelaatti on?

Mitä järkeä on myydä apteekissa 15mg gluconaattia, jos se vastaa placeboa? Jollain jennki sivustoilla suositeltiin gluconaatin päiväannokseksi 200-350mg jotta sillä oli vaikutusta. Yleensä netin sinkki sivustoilla kuitenkin varoitellaan enempi liiasta sinkistä vaikka näillä näkymin sinkin yliannoselu näyttää jokseenkin mahdottomalta.

Mistä siis on kyse?

Sinkit alkaa loppua. Kysytääs taas. Tullut tarjolle myös sitraattina ja asetaattina. Jos asetaatti on samanhintaista kuin glukonaatti niin olisiko se parempi valinta?

Pitääpä kaivaa tarkemmin...

Supplements

A number of zinc supplements are commercially available, including zinc acetate, zinc gluconate, zinc picolinate, and zinc sulfate. Zinc picolinate has been promoted as a more absorbable form of zinc, but there are few data to support this idea in humans. Limited work in animals suggests that increased intestinal absorption of zinc picolinate may be offset by increased elimination (5)

A Practitioners Guide To Zinc Supplements And How Your Body Uses Zinc

Bioavailability Of Different Forms Of Zinc Supplements

There are many forms of zinc compounds. The percentages of zinc in the compounds that Metabolics supplies is given below:

Zinc Picolinate 20%
Zinc Ascorbate 15%
Zinc Chloride 48%
Zinc Sulphate 22%
Zinc Carbonate 52%
Zinc Citrate 31%
Zinc Bisglycinate 25%

Triple Zinc- combination of Zinc citrate, zinc sulphate, and zinc picolinate

Zinc Formula- a combination balance of zinc bisglycinate and copper citrate

There is not much substantial evidence of greater effectivity of one form of zinc over another as absorption of zinc in the body is subject to so many variables.

However, a small research study (15 healthy young adults in a randomised, double blind three way cross over study, receiving 10mg of elemental zinc as a supplement without food just published (20 November 2013) found that the bioavailability of zinc citrate was 61.3% , of zinc gluconate was 60.9% and of zinc oxide was 49.9 % Previous zinc intake may affect zinc bioavailability studies.

Miksi syödä lisäravinne-sinkkiä? Mistä tiedät, ettei sitä ole enemmän haittaa kui hyötyä?

 

Hesarissa oli 7.5.2013 pieni juttu, jonka mukaan "Sinkin sanotaan korjaavan solujen syöpämuutoksia. Koehenkilöillä sinkki kuitenkin lisäsi syövänriskin kahdeksankertaiseksi." (boldaus minun)

Lisäksi oli vielä aspartaatti tarjolla.

Picolinaatilla on saatu parempia tuloksia, mutta hinta on myös rivakka, joten kysymys olisi siitä onko picolinaatti hintansa väärtti?

Zinc picolinate has been promoted as a more absorbable form of zinc, but there are few data to support this idea in humans. Limited work in animals suggests that increased intestinal absorption of zinc picolinate may be offset by increased elimination (5).  

 

En maksaisi kalliimpaa hintaa.

Laitatko sen tutkimuksen.

According to results published in the

Journal of the National Cancer Institute, researchers from the National Institutes of Health and Harvard Medical School have reported that high supplementation with zinc, more than 100 mg/day, increased the incidence of prostate cancer in men more than 2-fold. Zinc supplementation of 100 mg/day or lower did not increase the risk of prostate cancer.

Association between zinc intake and risk of digestive tract cancers: a systematic review and meta-analysis.

RESULTS:

Nineteen studies with approximately 400,000 participants were included in this meta-analysis. The pooled relative risk (RR) of overall digestive tract cancers for the highest versus lowest categories of zinc intake was 0.82 (95% CI: 0.70-0.96; p = 0.013). Comparing the highest with lowest categories, higher zinc intake was significantly associated with reduced colorectal cancer risk (pooled RR = 0.80, 95% CI: 0.70-0.92; p = 0.002), while zinc intake was not statistically associated with gastric cancer risk (pooled RR = 0.91, 95% CI: 0.64-1.29; p = 0.581) or esophageal cancer risk (pooled RR = 0.72, 95% CI: 0.44-1.17; p = 0.187). However, subgroup analyses showed that zinc intake was significantly associated with esophageal cancer risk and gastric cancer risk in Asia, but not in America and Europe.

CONCLUSIONS:

Dietary zinc intake was inversely associated with digestive tract cancers, especially colorectal cancer risk in this study.

Zinc and copper levels in bladder cancer: a systematic review and meta-analysis.

Bladder cancer patients demonstrated significantly lower levels of serum Zn (three studies, random effects standard mean deviation (SMD): -1.072, 95 % CI: -1.489 to -0.656, P <0.0001), markedly higher levels of serum Cu (three studies, random effects SMD: 1.069, 95 % CI: 0.302 to 1.836, P = 0.006) and urinary Zn (three studies, random effects SMD: 2.114, 95 % CI: 0.328 to 3.899, P = 0.02) compared with controls. No obvious difference was observed in urinary Cu levels between bladder cancer patients and controls (two studies, random effects SMD: 0.153, 95 % CI: -0.244 to 0.55, P = 0.449). No evidence of publication bias was observed. In conclusion, the disorder of Zn and Cu is closely associated with bladder cancer. Frequent monitoring and early intervention should be recommended.

Sinkkiä siksi, että puolivegaanisena sitä ei juurikaan ruuasta irtoa. Oireita joihin näyttää auttavan on karttakieli, kynsien epämuodostumat ja ruokahaluttomuus. Mutta olisi tosiaan kiva saada jotain arviota mikä annoskoko olisi optimaalinen?
