Gary Brecka's Supplement Stack: What the "Ultimate Human" Actually Takes and How to Build It at X-Optimum

Warning: reading this article may result in you auditing your biology, ordering blood work you didn't know you needed, and developing strong opinions about methylated B vitamins.

If you've spent any time in the wellness corner of the internet recently, you've almost certainly encountered Gary Brecka. The human biologist, co-founder of 10X Health System, and host of The Ultimate Human podcast has a knack for making complex biological concepts land with the force of a perfectly placed jab. He talks about NAD+ and MTHFR gene mutations with the same casual energy most people use to talk about the weather, and somewhere in that two-hour conversation, you find yourself genuinely alarmed that you've been taking folic acid instead of methylfolate your whole life.

Brecka's philosophy is rooted in a simple but powerful idea: you cannot optimize a system you haven't measured. Before he recommends a single supplement, he wants your bloodwork. He wants your genetic markers. He wants to know what your body is actually deficient in before he starts adding things to it. It's the biological equivalent of diagnosing a car before randomly replacing parts.

That said, his personal supplement stack — the compounds he uses daily — is well-documented, deeply researched, and frankly, very achievable. And a significant portion of it aligns directly with what X-Optimum Wellness offers.

Let's break it all down.

Who Is Gary Brecka?

Gary Brecka spent over two decades in the life insurance industry as a mortality expert, using biometric data to predict how long people would live. He got uncomfortably good at it. Eventually, he realized that the same data that predicted death could also be used to engineer longevity — and pivoted hard into functional medicine and human optimization.

He's worked with high-profile clients including UFC president Dana White, whose transformation under Brecka's protocol became one of the most viral wellness stories of 2023. Dana White publicly credited Brecka with changing his life, and the internet responded by making Gary Brecka the most Googled biohacker in America.

His core message: most people aren't sick, they're deficient. Fix the deficiencies. Support the biology. Watch the results compound.

Gary Brecka's Full Supplement Stack (2026)

Based on his podcast appearances, interviews, and public statements, here is the confirmed Gary Brecka supplement list:

It's a serious stack. The kind that makes your medicine cabinet look like a small pharmacy. But the underlying logic behind each one is sound, and Brecka is meticulous about explaining why each compound earns its place.

The Brecka-to-X-Optimum Matchup

Here's the part you've been waiting for. Let's go through Brecka's stack and map each pillar to the X-Optimum product that covers it.

1. Creatine — "One of the Most Validated Supplements on the Planet"

Brecka is a vocal creatine advocate. He uses it daily and cites it for both physical performance and cognitive function — specifically its role in ATP regeneration and brain energy metabolism. His preferred dose is 1.5g of liposomal creatine, though he acknowledges the standard 3–5g monohydrate dose is well-supported in the literature.

X-Optimum match: Optimized Creatine Monohydrate — $21.99

Straight creatine monohydrate, the most researched form in existence. If Brecka trusts creatine enough to take it every single day for brain and body, this is your starting point.

2. Multivitamin — "Not All Vitamins Are Created Equal"

This is where Brecka gets particular. He doesn't just want a multivitamin. He wants a methylated multivitamin — one that uses activated B-vitamin forms (methylfolate, methylcobalamin, hydroxocobalamin) that bypass the MTHFR gene bottleneck. He estimates up to 44% of the population has some form of MTHFR variation that impairs their ability to process standard synthetic folic acid and B12.

X-Optimum match: Optimized Multivitamin — $17.99

Foundational daily micronutrient coverage. For men specifically, the Optimum Male Multivitamin ($17.99) is formulated with performance and hormone support in mind. For women, the Optimum Woman Multivitamin ($17.99) covers the female-specific nutrient profile Brecka often references.

3. Resveratrol — "The Most Powerful Polyphenol for Longevity"

Brecka has cited resveratrol — particularly the piceid form for bioavailability — as a key part of his anti-aging stack. The mechanism: resveratrol activates sirtuins, a class of proteins that regulate cellular aging, DNA repair, and inflammation. He typically pairs it with magnesium and zinc for synergistic antioxidant defense.

X-Optimum match: Optimized Resveratrol — $19.99

Trans-resveratrol for sirtuin activation and cellular longevity — exactly what Brecka is reaching for.

4. NAD+ — "Your Battery Pack for Every Cell in Your Body"

If Gary Brecka has a signature compound, it's NAD+. He describes it as the cellular battery that powers everything from mitochondrial function to DNA damage repair. NAD+ levels decline with age — sharply — and Brecka considers replenishing them non-negotiable for anyone serious about performance and longevity.

X-Optimum match: Optimized NAD+ — $21.99

X-Optimum's NAD+ formula is formulated with Quercetin and Resveratrol alongside the NAD+ — a stacking approach that mirrors exactly what Brecka recommends for synergistic longevity benefits.

5. NMN — "The Precursor That Refills the Tank"

NMN (Nicotinamide Mononucleotide) is a direct NAD+ precursor. Brecka uses both NAD+ directly and NMN, understanding that the two compounds hit the pathway from different angles. NMN crosses cell membranes more efficiently and is converted to NAD+ intracellularly, while supplemental NAD+ provides more immediate systemic availability.

X-Optimum match: Optimized NMN — $19.99

Stack it with the NAD+. That's how Brecka runs it, and there's solid literature supporting the dual approach.

6. Collagen — "The Scaffolding Your Body Runs On"

Brecka recommends daily collagen supplementation for joint integrity, skin elasticity, and connective tissue health. He emphasizes grass-fed, bovine-sourced collagen for the richest Type I and Type III peptide profile. He's said repeatedly that collagen is one of the most overlooked foundational supplements — not glamorous, but quietly holding your whole structure together.

X-Optimum match: Grass-Fed Bovine Collagen Peptides Powder (Chocolate) — $24.99

Grass-fed, bovine-sourced, Type I and III collagen. Checks every box Brecka has publicly cited. And it's chocolate-flavored, which means your morning routine just got significantly more enjoyable.

7. The Sleep Stack (Magnesium + L-Theanine + Melatonin) — "Sleep Is the Most Anabolic Thing You Can Do"

Brecka is emphatic about sleep quality. His pre-bed protocol includes magnesium threonate (for nervous system relaxation and sleep architecture), L-theanine (for calm without sedation), and low-dose melatonin (for sleep onset). He takes all three 30–60 minutes before bed and considers this stack non-negotiable.

X-Optimum match: Better Sleep Strips — $17.99

Fast-dissolving oral strips designed for rapid absorption before bed — hitting the exact sleep-support window Brecka prescribes. Also check out the Optimized Sleep Formula ($17.99) for a comprehensive capsule-based sleep stack.

8. Probiotics — "Your Gut Is Your Second Brain"

Brecka consistently emphasizes gut microbiome optimization as a foundational pillar. He talks extensively about the gut-brain axis, how dysbiosis drives inflammation, and how an optimized microbiome is prerequisite to everything else working properly. "You can eat the cleanest diet in the world, but if your gut can't absorb it, you're just expensive urine," is the kind of Brecka line that sticks with you.

X-Optimum match: Optimized Super Probiotic — $17.99

A high-potency multi-strain probiotic for microbiome diversity and gut-brain axis support. The foundation Brecka insists has to be in place before anything else will work optimally.

9. Stress Regulation — "Cortisol Is the Silent Killer of Peak Performance"

Brecka talks frequently about cortisol dysregulation as a root cause of brain fog, fatigue, weight gain, and hormonal imbalance. He emphasizes adaptogenic support — compounds that regulate the HPA (hypothalamic-pituitary-adrenal) axis rather than simply stimulating or sedating it.

X-Optimum match: Optimized Ashwagandha — $14.99

KSM-66 ashwagandha, the most clinically studied adaptogen for cortisol regulation and HPA axis support. Exactly what Brecka is reaching for when he talks about "modulating the stress response without blunting your edge." For the full adaptogen stack, the Ashwagandha and Shilajit Adaptogen Complex ($17.99) adds shilajit's fulvic acid and mineral matrix for compounding stress-adaptation benefit.

10. Cardiovascular & Blood Flow — "Your Heart Is Hardware, Not a Metaphor"

Brecka places enormous emphasis on vascular health and nitric oxide production — particularly the role of blood flow in oxygen delivery, cognitive function, and sexual health. He consistently notes that most Americans are deficient in the dietary precursors needed to sustain healthy nitric oxide levels.

X-Optimum match: Optimized Nitric Oxide — $17.99

L-arginine and L-citrulline-based nitric oxide support for vascular health, circulation, and peak hemodynamic output. Pure Brecka territory.

The Gary Brecka X-Optimum Quick-Start Stack

If you want to follow the Brecka protocol without having to rebuild your supplement cabinet from scratch, here's the X-Optimum entry stack mapped directly to his core pillars:

The Bottom Line

Gary Brecka's approach isn't about chasing trends or stacking 30 supplements because some podcast told you to. It's about understanding why your biology is underperforming and targeting those specific gaps with precision. His emphasis on measurement first, supplementation second is genuinely refreshing in an industry that's often more interested in selling than explaining.

But here's what's clear from his stack: the foundational compounds he returns to over and over — creatine, NAD+, NMN, resveratrol, collagen, quality sleep, gut support, and stress regulation — are not exotic or inaccessible. They're the same categories X-Optimum was built around: precision, quality, and biological function over marketing fluff.

If you're a fan of Brecka's approach and want to start building your own biology-first protocol, X-Optimum has the lineup to do it without breaking the bank.
