I was speaking to a dietitian who regularly advises athletes and he stressed what he called significantly rampant zinc deficiency in men which adds to the already poor T/E ratio in many men. He claimed to have not had a male client who wasn't deficient in zinc and the first thing he has his clients do is begin zinc supplementation.
Agree/Disagree/Thoughts?

Guess what types of foods are high in zinc? Its the same types we have been eating for millions of years......

its the types of foods that have gone off just about everyones menus in the past 100 years. Game meat, unprocessed grains and starch, lots of veggies etc.

Zinc is one of the only supplements worth taking.
A well known T booster.

A lot of it depends on the makeup of one's overall diet. There are plenty of foods that are very healthy foods which have mineral inhibitors within them (legumes for example). This doesn't mean that the zinc contained within them and even the zinc in a another item of the meal doesn't get absorbed, but if a diet is lacking in diversity it can be quite easy to develop a deficiency.
Generally I'm quite skeptical about shoveling down a down of pills because the problems can be solved naturally by consuming a broader menu.

its NOT a test booster. but if you are deficient in zinc then your test levels wont be at their optimal levels.
taking zinc merely gets your test levels back to where they SHOULD be

it simply helps keep test from being oxidized, so yeah it isn't a "booster"

Also a warning about supplementing with Zinc - remember that it IS a heavy metal.
So if you get adequate levels in your diet and you increase your intake with multiple supplements you do have a risk of overdose - which creates more problems than it is worth.
Additionally, it can interact with / effect other metals in the body creating problems with Copper and Iron.

Health Risks from Excessive Zinc
Zinc toxicity can occur in both acute and chronic forms. Acute adverse effects of high zinc intake include nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches [2]. One case report cited severe nausea and vomiting within 30 minutes of ingesting 4 g of zinc gluconate (570 mg elemental zinc) [78]. Intakes of 150?450 mg of zinc per day have been associated with such chronic effects as low copper status, altered iron function, reduced immune function, and reduced levels of high-density lipoproteins [79]. Reductions in a copper-containing enzyme, a marker of copper status, have been reported with even moderately high zinc intakes of approximately 60 mg/day for up to 10 weeks [2]. The doses of zinc used in the AREDS study (80 mg per day of zinc in the form of zinc oxide for 6.3 years, on average) have been associated with a significant increase in hospitalizations for genitourinary causes, raising the possibility that chronically high intakes of zinc adversely affect some aspects of urinary physiology [80].
The FNB has established ULs for zinc (Table 3). Long-term intakes above the UL increase the risk of adverse health effects [2]. The ULs do not apply to individuals receiving zinc for medical treatment, but such individuals should be under the care of a physician who monitors them for adverse health effects.
Table 3: Tolerable Upper Intake Levels (ULs) for Zinc [2]
Age - - - - - - - - Male - / - Female - / - Pregnant - / - Lactating
0 to 6 months - - - 4 mg- / - 4 mg
7 to 12 months - - - 5 mg - / - 5 mg

REVIEW ARTICLES
Zinc toxicity
GJ Fosmire
Department of Nutrition, College of Health and Human Development, Penn State University, University Park 16802.
Although consequences of zinc deficiency have been recognized for many years, it is only recently that attention has been directed to the potential consequences of excessive zinc intake. This is a review of the literature on manifestations of toxicity at several levels of zinc intake. Zinc is considered to be relatively nontoxic, particularly if taken orally. However, manifestations of overt toxicity symptoms (nausea, vomiting, epigastric pain, lethargy, and fatigue) will occur with extremely high zinc intakes. At low intakes, but at amounts well in excess of the Recommended Dietary Allowance (RDA) (100-300 mg Zn/d vs an RDA of 15 mg Zn/d), evidence of induced copper deficiency with attendant symptoms of anemia and neutropenia, as well as impaired immune function and adverse effects on the ratio of low-density- lipoprotein to high-density-lipoprotein (LDL/HDL) cholesterol have been reported. Even lower levels of zinc supplementation, closer in amount to the RDA, have been suggested to interfere with the utilization of copper and iron and to adversely affect HDL cholesterol concentrations. Individuals using zinc supplements should be aware of the possible complications attendant to their use.

Hate to say it but that's pretty much the same thing. Okay, "test restorer"? Semantics, my friend.
I'd also like to point out that zinc supplementation makes those white spots on fingernails disappear.
In a world of supplements that don't do anything, good old zinc is a shining beacon of success.
Other supplements that actually work:
Magnesium - sleep
B Vitamins - energy
Prohormones - muscle gains
Apple Cider Vinegar - digestion
L-Tryptophan/5-HTP - sleep
Adrenal Cortex Extract - energy
And that's about it. Practically everything else being sold is a placebo.
