I've been taking zinc since my 20s but had stopped for some time. Then a few years back started having to get up 3 or 4 times a night to pee a tiny bit so got back on it and fixed that problem. I also take Saw Palmetto daily and between the two got my PSA number down as the doc was wanting me to go for a prostate biopsy. Tips for anyone going for a PSA test. No ejaculation for 3 days before the test and avoid doing anything like riding a bike as that puts pressure on the prostate and irritates it raising the PSA. The doctor who invented that test now claims it is used wrong and causing a lot more aggressive treatments than are needed to cure cancers that are likely not there. Greedy surgeons and the capitalistic medical system loves finding ways to make money even if it screws you up. Same thing with mammograms for the ladies.
Selenium is another mineral that is good for heart and prostate health. Like zinc it's pretty cheap.
My daily list of things I take to help this aging body out is, Zinc citrate 50mg, selenium, iron, 2 - Omega3 gel caps, VitA+B gel caps, B3, magnesium citrate, B-complex with a B-12 under the tongue at bedtime with my melatonin, St. John's Wort for depression, Saw Palmetto, 5-HTP for fibro and twice daily 500mg vit C.
I make my own "00" caps of tumeric root, MSM, (methylsulfonylmethane), to help with arthritis.
To prevent another stroke and fend off the dementia that my birth mother died from, I eat a lot of coconut oil and other healthy oils like pumpkin seed, (great for the prostate and high in Mg), avacodo, walnut, (also great for the prostate and the brain). No canola oil in our house with peanut oil or coconut oil for baking. Coconut oil is great for frying too and has very little taste. Organic expelled oils are best.
Love peanut butter but good old Skippy is all hydrogenated oils so I buy Adam's natural peanut butter that you have to mix up and keep in the fridge to keep it mixed. Local clover honey too.
Haven't eaten at McDonalds for over 30 years and avoid deep fried foods like the plague they are. No pop either and diet coke is worse for you than regular tho it's shit as well as they use high fructose corn syrup which promotes fatty liver disease even in children, obesity and diabetes. There's a new form of HFCS out now that just says fructose on food labels but is 90% fructose from GMO corn so watch for that.
Any processed food is going to age you faster and get you on the treadmill to multiple pharma drugs that will keep you alive longer until your bank account is drained then you'll die a painful death when you can't afford them any more.
I could go on for pages but if you care about your health you'll do a little research and shop carefully.
I am on no pharma drugs and rarely even take an aspirin. Haven't had a cold or flu in decades and will never get a flu shot. Tylenol will blow out your liver.
Stay healthy out there!
