Our Founder is 72.
His Biology is 27.

Built by a board-certified cardiologist with 30+ years of clinical experience, not a marketing team.

Dr. Gladden walked away from medicine to prove biology could be optimized, not just managed. At 72, his biological age tests at that of a man in his early 27. He doesn't recommend these products. He uses them himself every single day.

He snowboards extreme terrain. Mountain bikes. Jumps out of helicopters to go backcountry skiing. Things most people in their 40s have already stopped doing.

Every product in this store is what he takes to keep doing it.
Not what he recommends in theory. What he personally uses or prescribes every single day.

My doctor actually mentioned nitric oxide support to me during a routine appointment and i found this through Dr Gladden's podcast. Three months in. Blood pressure is down slightly and i feel way better on the bike. My wife keeps asking why i seem younger lol

Ok so i was fully prepared to return these. took them for about 10 days and thought nothing was happening. then i had a week where i ran out and forgot to reorder and that's when i realized something had actually been working. hard to explain but the best way i can describe it is that my brain just felt... quieter and faster at the same time. been on them 3 months now

Bought these because my buddy who's a doctor wouldn't stop talking about molecular hydrogen. Figured i'd try it. I'm not someone who writes reviews but i'm 58 and i haven't felt this good after a workout since my 40s. Recovery is just faster.

I'll be honest the price made me hesitate for like two weeks. Finally bought them. Wish I hadn't waited. I take one in the morning with water before coffee and I just feel... on. Not wired. Just on. My wife asked what I was taking and she's now on them too lol

I have a really hard time shutting my brain off at night. Like genuinely hard. I've tried magnesium, ashwagandha, melatonin, all of it. The melatonin stopped working years ago and made me groggy anyway. This is completely different. I don't feel like I took something. I just... fall asleep. Like a normal person. I don't know how.

Took this for the first time on a Sunday night after a stressful week and slept 7.5 hours straight. Woke up and actually felt rested which hasn't happened in maybe two years. Ordered a second bottle before the first one was done

I've tried turmeric capsules before and they did absolutely nothing. My trainer told me the bioavailability on regular curcumin is terrible and that's why. Picked up UltraCur Pro kind of reluctantly. About 5 weeks in the knee pain I've had after runs for like two years is noticeably better. Not gone but like... 60% better. I'll take it

Genuinely did not think this would be different from every other curcumin thing I'd tried. I was wrong. I do manual work and I'm 54 and the inflammation in my hands and lower back has been something I just accepted. A month on this and I've had to reconsider that. Still can't fully explain it but something is working

Started taking this about 6 weeks ago. I run 4x a week and the difference in how i feel on mile 4 and 5 vs before is real. Less effort, better breathing. I don't know how else to say it. just easier.

Questions?We've got answers.

Every product in this store has been personally vetted and recommended by Dr. Jeffrey Gladden, a board-certified cardiologist. Gladden Certified means it cleared his clinical standard. Not a marketing team's decision.

Most supplements on Amazon are white-label products, generic formulas sourced from the same factories, rebranded and resold. Every product here is selected because of its clinical quality, dosage accuracy, and bioavailability. You're getting what actually works, not what looks good on a label.

It depends on the product and your starting point. Most people notice something within 2–4 weeks of consistent daily use. The deeper benefits, cellular, hormonal, cardiovascular, compound over 2–3 months. These are protocols, not quick fixes.

Most people take these alongside their existing stack without issue. If you're on prescription medications, check with your doctor before adding anything new — especially if those medications affect the same system the supplement targets.

None known when taken as directed. These are natural, clinically studied compounds. If you experience anything unexpected in the first few days, take with food and reduce to half dose until your body adjusts.

None. Pause, skip, or cancel your subscription anytime. No questions, no hoops, no hidden fees.

Some benefits you'll feel like more energy, less soreness, better sleep, clearer thinking. Others show up in your bloodwork and biomarkers over time. Dr. Gladden's recommendation is to track how you feel at 30, 60, and 90 days and compare your baseline labs before and after.
