They also have a good backgrounder on Zinc and Health which includes

  • "Zinc has two standard dosages. The low dosage is 5-10mg, while the high dosage is 25-45mg. The low dose works well as a daily preventative, while the high dosage should be taken by anyone at risk for a zinc deficiency."
  • "Different forms of zinc contain different amounts of elemental zinc, which refers to the weight of the zinc molecule by itself"
  • "Zinc should be supplemented daily."
  • Consistant proof of benefits to diabetes, depression, acne, testosterone, viral warts (topical) , cognition after stroke, common cold

Overview Diabetes and vitamin D contains the following summary

  • Diabetes is 5X more frequent far from the equator
  • Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
  • Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
  • Sedentary people get less sun / Vitamin D
  • Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
  • Elderly get 4X less vitamin D from the same amount of sun
        Elderly also spend less time outdoors and have more clothes on
  • All items in category Diabetes and Vitamin D 381 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

  • Appears that >2,000 IU will Prevent
  • Appears that >4,000 IU will Treat , but not cure
  • Appears that Calcium and Magnesium are needed for both Prevention and Treatment
        which are just some of the vitamin D cofactors

Zinc and prediabetes on the web


BACKGROUND:
This study evaluated the effects of zinc supplementation on glycemic control, other cardiometabolic and anthropometric parameters, and disease progression in prediabetes.

METHODS:
A randomized double-blind placebo-controlled Phase 2 clinical trial was conducted over a 12-month period in 200 subjects (43% male; mean [± SD] age 51.8 ± 7.3 years), randomly assigned (1:  1) to the treatment or control group. The treatment group received zinc (20 mg daily). Subjects were evaluated at baseline and at 1, 3, 6, and 12 months. The primary outcome was the change in glycemic control from baseline. Multiple regression analyses were performed, with change in outcome variables after intervention from baseline used as continuous dependent variables.

RESULTS:
In both groups, mean serum zinc concentrations prior to the trial were below normal (15.29-21.41 μmol/L). During the 12-month follow-up, a significantly higher percentage of participants developed type 2 diabetes in the control compared with zinc-treated group (25.0% vs 11.0% respectively; P = 0.016).

  • Fasting plasma glucose (FPG),
  • 2-h glucose levels in the oral glucose tolerance test (OGTT),
  • homeostasis model assessment of insulin resistance (HOMA-IR),
  • total cholesterol (TC), and
  • low-density lipoprotein cholesterol (LDL-C)

were significantly lower in the treated group, with significant improvement in β-cell function. In all four regression models, the best predictor of the dependent variables (i.e. change in FPG, 2-h glucose in the OGTT, HOMA-IR, and homeostatic model assessment of β-cell function) was zinc treatment.

CONCLUSIONS:
Zinc supplementation reduced blood glucose and insulin resistance while improving β-cell function. Furthermore, supplementation reduced disease progression to diabetes and had beneficial effects on TC and LDL-C.
