Three primary pillars, with additional supporting ingredients.
Each chosen for a specific purpose, dosed at levels that actually matter.
Most supplement companies hide their doses, under-dose key ingredients, and make claims they can't back up.
We took a different approach:
No proprietary blends. Every dose individually listed.
We match the doses used in actual clinical research—not pixie-dusted amounts for label claims.
While competitors require 6-8 capsules, we packed 12 ingredients into an easy daily routine.
“I reviewed the ingredient list and dosages in RBRN's Vitality Complex. The ingredients each have a substantial body of published research behind them, and the amounts included are consistent with the doses used in that research.
”
“Most men's supplements are either underdosed or hiding what's actually in each dose. RBRN is one of the few I've seen that matches clinical study doses across the board, and conveniently includes many of the ingredients I recommend to clients.
”
I've been searching for a product like this. I love that they let the research speak for itself, and don't insult my intelligence with vacuous claims that can't possibly be true.
RBRN is the first daily supplement I've had where I never miss a dose. I love that it's only 3 pills a day.
I was genuinely impressed by how honest they were about the ingredients. I trusted them, and I'm glad I did.
Found myself a brand I trust in an industry that desperately needs more of them. I've never seen such ingredient research transparency before, which is why I was willing to be one of the first to try it out.

Subscribe & SaveWe started RBRN because we were turning 40 ourselves, and knew that men our age were looking to reclaim their edge again. All kinds of research was showing that certain supplements could help offset some of the environmental damage, dietary deficiencies and sedentary lifestyle impacts affecting modern men, but when we looked for these supplements all we saw was SuppSlop — junk claims, fake reviews, and proprietary formulas that couldn't be trusted. So we made our own, and set out to market to the men who care about what they put in their bodies, do their homework, and aspire to feel their biological best again. We can't wait for you to try it.

RBRN Vitality Complex is a daily testosterone support and cellular energy formula for men -- twelve research-backed ingredients working both fronts in 3 capsules a day. The goal is simple: help men get back to their biological standards for hormonal balance, cellular energy, and stress resilience. Every ingredient is dosed at levels supported by published clinical research, and every dose is printed on the label.
RBRN Vitality is formulated for men looking to support their health proactively — whether that means maintaining energy levels, supporting healthy aging, or addressing the natural hormonal shifts that come with time.
Several ingredients in the formula have been studied for their effect on testosterone. In published trials, fenugreek (500-600mg/day) was associated with increases in free testosterone in resistance-trained men; tongkat ali (200mg of a 200:1 extract) with normalized testosterone levels in men experiencing age-related decline; and a 2026 meta-analysis of 23 randomized trials found ashwagandha raised testosterone in men by an average of 57 ng/dL. Zinc and boron are cofactors in testosterone synthesis and metabolism. What that means for you depends on your baseline, age, sleep, training, and body composition -- men starting lower tend to see the most movement. RBRN is designed to support healthy testosterone levels already within the normal range; it is not a drug and does not treat any medical condition. If you suspect clinically low testosterone, start with bloodwork and your doctor.
Two ingredients in the formula have human data on sexual function. In a 12-week randomized trial of 120 men aged 43-70, fenugreek was associated with significant improvements in self-reported sexual function -- including morning erections -- alongside measured increases in testosterone. In a separate 12-week trial of 109 men aged 30-55, tongkat ali was associated with a 14% improvement in libido scores. RBRN includes both, at 500mg and 200mg respectively, as part of its testosterone support side. These are supportive effects observed in healthy men -- not a treatment for any medical condition.
If you're comparing testosterone boosters, here's how RBRN approaches it: five ingredients -- fenugreek, tongkat ali, zinc, boron, and ashwagandha -- support healthy testosterone levels through different mechanisms, each at doses used in published research. Then we add the front most testosterone products ignore: cellular energy, with 500mg NMN and PQQ. One formula, two fronts, plus stress resilience, foundation nutrients, and absorption support. And rather than promising a number, we publish the research and the doses so you can see exactly what the evidence supports.
We're one of the first supplements to combine NMN for cellular energy with testosterone-supporting botanicals and adaptogens in one formula. But what we're most proud of is that we're honest about the evidence. We tell you which ingredients are well-researched, which have growing evidence, and which are still early on. We don't pretend everything has decades of human trials, or make bogus claims about results you should expect. We're transparent about dosage, and kept it to 3 capsules a day for convenience. And our Customer Support is live humans, easily reached, and dedicated to providing you with a positive RBRN experience. Reach out to us for any reason!
Four things: ingredients with published human research, doses that match what the studies actually used, full label transparency with no proprietary blends, and support for the systems that decline alongside testosterone -- cellular energy chief among them. Most testosterone supplements for men over 40 chase a single hormone pathway and underdose the rest. RBRN was formulated around all four: five testosterone-support ingredients at researched doses, 500mg NMN plus PQQ for cellular energy, and every dose printed on the label.
Most supplements lump ingredients together so you can't tell what you're actually getting. We list every ingredient and its exact dose so you can verify the research yourself. Check out our formula page, or use the dropdown in the header to understand why each ingredient was chosen and the research that supports the decision.
