It's not just age

Same age.
Less testosterone.

Average total testosterone, American men aged 15 to 39. National survey averages, 1999 vs. 2016.1

Average total testosterone in American men aged 15 to 39 fell from 605 ng/dL in 1999 to 451 ng/dL in 2016, a drop of about 25%.

~1%

A year. That's how fast average testosterone fell in a study of more than 1,500 men, independent of age.2

It isn't just you, and it isn't just getting older. Today's man is up against more than his father was.

Vital Man is built to help you hold your ground: two capsules a day to support healthy testosterone production, drive and male vitality.*

Population trends are context, not a diagnosis. If you're concerned about low testosterone, talk with your doctor about testing.

Why bison

Pick your
animal.

Not all testicle is equal. Independent university testing measured the testosterone naturally present in freeze-dried testicle powder from three animals.3 It wasn't close.

Vital Man's label lists its testicle as bison/bovine. This compares raw ingredients. It doesn't measure testosterone levels in people who take Vital Man, and Vital Man is not a hormone product.

Tongkat Ali root and leaves

The LJ100® difference

Not all Tongkat Ali is created equal.

Plenty of Tongkat on the shelf is plain, unstandardized root powder. LJ100® is made to the same spec every batch, and it's been tested against placebo in actual humans. Vital Man uses 200 mg, the daily dose from that research.

  • Clinically studied in humans
  • 200 mg, the dose used in the research
  • Results compared against placebo
  • Guaranteed 40% glycosaponins + 22% eurypeptides

Average total testosterone, ng/dL

In a 12-week randomized, placebo-controlled trial, men aged 50 to 70 whose total testosterone was under 300 ng/dL at the start took 200 mg a day. By week 4, the increase was significantly greater than placebo, and it stayed that way at weeks 8 and 12. Fatigue and aging-male symptom scores also improved versus placebo.4

Standardized.
Studied.
Every amount on the label.

Group averages measured at the start and weeks 2, 4, 8 and 12. The two groups started at different levels, so the comparison is about the change. Ingredient research funded by the extract's manufacturer, not a study of finished Vital Man. Individual results vary.

By the 1880s, the animal that once covered the Great Plains was nearly gone. Ranchers, tribes and conservationists brought it back, one herd at a time.

Human Nature works with 50+ independently owned bison ranches and is a Partner in Restoration with the National Bison Association. Better sourcing should support the animal, the grassland, the rancher and the man taking the finished formula.

TRT is a prescription treatment for diagnosed low testosterone. Because it supplies testosterone from outside the body, it can suppress the body's own production, and stopping is something to plan with your doctor. Vital Man is a dietary supplement, not a substitute for TRT. Supplement features vary by brand; check the current label.

Good questions

Know before
you start.

Still wondering? support@ourhumannature.com

Is this TRT or a hormone?

No. Vital Man is a dietary supplement, not testosterone replacement therapy or a prescription treatment, and no hormones are added. Organ tissues naturally contain biological compounds. If you use TRT or other hormone therapy, talk with your doctor before adding Vital Man.

How soon will I notice a difference?

There's no universal timeline. The 200 mg LJ100® study ran 12 weeks, and the difference versus placebo was significant by week 4, so give it at least a month of consistent daily use and compare your weeks, not a single day. Individual experiences vary.

Is Vital Man clinically proven?

The LJ100® ingredient has human clinical research at 200 mg a day. That doesn't establish clinical proof for the finished Vital Man formula; study populations, designs and durations differ. The original sources are linked at the bottom of this page.

What's in it?

Each two-capsule serving contains 700 mg testicle (bison/bovine), 200 mg LJ100® Tongkat Ali (Eurycoma longifolia) root extract and 100 mg heart (bovine/bison). Gelatin is the only other ingredient. One pouch holds 60 capsules, a 30-day supply.

How do I take it?

Two capsules daily with food and water, or as directed by your healthcare professional.

Should I talk to my doctor first?

Vital Man is intended for adult men. Talk with a qualified healthcare professional before use if you take prescription medication, including beta-blockers; use testosterone or other hormone therapy; or have liver disease, a heart-rhythm condition or a hormone-sensitive condition such as prostate cancer.

Can I skip or cancel?

Yes. Skip, pause or cancel anytime before your next charge. There's no commitment, and your price stays locked for as long as you subscribe.

What if it's not for me?

Contact us within 90 days of delivery for a product refund, opened or unopened. A physical return isn't normally required for a satisfaction-guarantee claim.
