Resveratrol is a natural polyphenol found in small amounts in red grapes and wine. Studies show resveratrol is a highly effective estrogen blocker and a potent aromatase inhibitor, minimizing negative estrogen effects and maximizing natural testosterone. Resveratrol also provides significant cardiovascular and neurological health benefits and activates fat burning. Two Rez-V™ softgels contain 600 mg of active pure trans-resveratrol, the type and amount required for an effective dose of this powerful science-backed ingredient.*

Benefits

  1. Controls estrogen in two ways*
  2. Acts as a potent estrogen blocker*
  3. Acts as a potent aromatase inhibitor*
  4. Increases natural testosterone levels*
  5. Protects against man-made environmental estrogens that lower testosterone*
  6. Stimulates fat burning*
  7. Promotes cardiovascular health*
  8. Exhibits prostate protectant effects, liver protective effects, and anti-aging effects*

Control Estrogen to Live Better and Look Better*

Active men naturally want high testosterone. "High-normal" testosterone gives you an advantage in building and maintaining a lean, muscular, hi-performance body – and it generally makes you feel great.

The trouble is, some testosterone naturally converts into estrogen through aromatization. And with elevated estrogen, you can easily gain fat, bloat with excess water, have a tough time even maintaining muscle mass and strength, and even impact your prostate health. Too much estrogen also signals the body, though negative feedback, to produce less testosterone.

While men need some estrogen to maintain cardiovascular health, it can cause many problems if it gets out of control.

Man-Made Estrogens Are Everywhere

Adding to the estrogen problem, many chemicals in the environment mimic estrogen. They're called xenoestrogens, and they're everywhere: in plastic bottles and bowls, shampoos, detergents, even toothpaste. Xenoestrogens are unavoidable and will find their way into your body every day.

Resveratrol: Estrogen Blocker

Resveratrol acts as a potent estrogen antagonist (blocker) while also acting as a "healthy" (weak) agonist in cardiovascular tissues (similar to the drugs clomiphene and tamoxifen). As a blocker, resveratrol occupies estrogen receptor sites, or biological "parking lots," so xenoestrogens can't "park" and activate the receptor – no activation means no negative effects.

Resveratrol: Aromatase Inhibitor

In higher concentrations, resveratrol also acts as an aromatase inhibitor, preventing the body from converting testosterone into estrogen, with the bonus of increasing testosterone. Resveratrol inhibits aromatase by reducing its expression and by binding to it. And, unlike pharmaceutical aromatase inhibitors, resveratrol doesn't decrease blood vessel function; it seems to improve it.*

Resveratrol: Fat Burner

Calorie deprivation activates a protein called SIRT1, which inhibits PPAR-gamma activity and causes your body to burn fat. Resveratrol activates this very same SIRT1 protein without you needing to diet excessively.*

Resveratrol: Supplement for Heath

Additionally, there's overwhelming scientific evidence that resveratrol provides potent cardiovascular benefits, anti-aging effects, and positive neurological effects. Many of these benefits stem from anti-oxidative and anti-inflammatory actions and gene modulation.*

By What Measure 2.0?

What are you expecting. "I feel 20 years younger." "I've lost 3% body fat." "I added 40 pounds to my bench press." "Everyone says how great I look." Is there a blood test to show me what (if anything) this stuff is doing?

Well worth getting

This is perhaps the best resveratrol supplement I've ever used. Not watered down, not just one of twenty-five different things in a formulation, just a well designed and effective product.

By What Measure?

I trust there is a benefit to this supplement, and it is what it claims to be. There is however, no definitive, measurable result that can verify its effectiveness. Had I engaged a medical blood laboratory for testing before and after starting use of this supplement, I might be able to offer some kind of objective evaluation of my experience. Absent that, I'll enjoy the emotional placebo effect that this wonderful supplement provides me.

My lab results indicate that since I began taking REZ-V my estrogen levels have dropped dramatically. For that reason, I continue to take it.

Best Resveratrol on market, w a small caution

Wonderful! You get what you pay for, and Biotest products are always excellent. Warning: in the case of Rez-V, all major studies on resveratrol require 1000-2000 mg, meaning doubling or tripling any resveratrol bottle recommended serving sizes as a minimum, if not more. Having said that, it really is worth it, and ALL resveratrol on the market knowingly underdoses their recommended serving size, or else the manufacturers would scare off consumers with the absurd sticker-shock quantities required. The reason I splurge/go through two bottles a month of Biotest's Rez-V is their high-efficacy delivery. I'm a lean 230 lbs guy, and studies all use 1000-2000 on normal people for proven results. But with the efficacy of Rez-V I feel confident going with the minimum true 1000-1200 effective single dose (5-6 capsules) for me. With any other company, I would definitely be shooting for the 2000mg range or more, typically meaning 10-14 pills a day. Only using 6 capsules a day of Rez-V seems far more reasonable to me than would I would need to do with any other brand. As former triathlete, NPC Heavyweight National Level Bodybuilder, and a longevity Biohacker, I believe two bottles a month is enough for almost anyone, even me. Good luck!

Review for somebody from Dominican republic

I think it was good I had a nice discountt on my 5 Rez-V purchase. But I have a problem with the delivery. It was on time but it was hold in my locker because it didn't have a code of membership I had to provide. Next time I'll be more expecific.

REZ-V

Subjectively, I always feel better - a bit stronger, more flexible, better 'emptying' experience when doing 'number one'. Good value - I get a month's supply at a price I can afford (on auto ship or coupon) and I 'feel' that it is doing what it claims. Disclosure: Nearly 60 years old and keeping' it up!

REZ-V TO THE RESCUE!

At age 72, I'm concerned with my T level as well as my E level. Taking REZ-V from BIOTEST not only keeps both in balance but helps with my prostate function. If you're not taking this supplement, you need to LEARN WHY YOU NEED IT!

Amazing product

I was having an issue with estrogen, I tried several other products that helped a little, within a week of using REZ-Z my levels dropped to normal, I am on low dose TRT, this was the only thing that worked. I recommend this product to everyone I know.

Great product

Like this supplement a lot, and Ill continue to use. I have subscribed now so it's delivered each month. No side effects at all, and feeling good on it. I first trialed it for 90 days, and had blood work done to measure T levels. Stacked it with Flameout. T levels went from 603 to 675. Overall very satisfied with this product.
