Zinc protects heart function in OSA
Zinc Is Indispensable in Exercise-Induced Cardioprotection against Intermittent Hypoxia-Induced Left Ventricular Function Impairment in Rats.
Directly relates zinc to cardiac health.
We explored how zinc affects heart function in the context of obstructive sleep apnea (OSA), specifically focusing on cases of intermittent hypoxia (IH). In a detailed study using male rats, researchers set up different groups: a control group and one that underwent 10 weeks of exercise training. Half of the rats in both groups were exposed to IH conditions to simulate the effects of sleep apnea.
The results were eye-opening. Rats that experienced IH showed notable impairment in their heart's left ventricular function, characterized by reduced ejection fraction and increased inflammation. However, when treated with zinc, these negative effects were significantly countered. Notably, those who exercised and received zinc treatment displayed improved heart function and antioxidant capabilities compared to their counterparts that did not receive zinc.
On the flip side, exercise alone did not provide the same protective benefits when zinc was absent. The findings suggest that zinc is essential not only for the heart's protection against the damaging effects of IH but also enhances the benefits of physical exercise. This research indicates the importance of zinc in potentially managing heart health in individuals suffering from sleep apnea.

Resolved insomnia
After confirming my zinc deficiency, I started this supplement. My severe insomnia and hair loss improved immediately, allowing me to get 6-7 hours of sleep instead of just 4.

Improved sleep quality
The magic zinc! After using it nightly for a month, I felt relaxed and started to sleep well. I noticed less hair loss, and my hair seems to be growing again.

Enhanced sleep patterns
I really appreciate this zinc formulation. When taken with magnesium at night, it helps me sleep soundly. I typically take 30-45 mg daily, ensuring to avoid calcium to maximise absorption.

Deeper sleep
I bought this zinc for my hair, but it also improved my sleep quality. I take it after dinner, and I've noticed deeper sleep alongside baby hair growth.

Sleep enhancement
We appreciate that this zinc formulation has copper in a healthy ratio. Taking this nightly, along with magnesium, helps with sleep. We consistently buy Jarrow Formulas Zinc Balance.
