Better Sleep Essentials contains highly bioavailable Zinc mono-L-methionine sulphate, Zinc aspartate, Magnesium aspartate, and vitamin B6. These ingredients are proven to support hormone health, including noticeable increases in Insulin-like Growth Factor – 1 (IGF-1) and Free Testosterone.
Selected hormones were assessed in response to a nightly supplementation regimen, over an 8-week period, with pre-post measures. A double-blind randomized study was conducted with the proprietary ingredients including 30 mg zinc mono-L-methionine aspartate, 450 mg magnesium aspartate, and 10.5 mg of vitamin B-6. Plasma zinc and magnesium levels were 0.0. to 1.04 µ/ML; 19.43 TO 20.63 MCG/ML AND p (0.84 TO 0.80 µG/ML; 19.68 TO 18.04 µG/ML, respectively (P,0.001).
Free testosteronein the control group increased 44.2 µg/ml (43% increase) compared to a decrease of -14.4 µg/ml (10% decrease) in the placebo group for an overall increase against placebo of 53.2% IGF-1 notably did not increase, as occurs with aging, and increased against the placebo group a total of 25.4%. IFG-I may mediate the action of GH on skeletal muscle as a paracrine agent.
