Ben Greenfield's Supplement Protocol: The Boundless Performance Stack, Available at X-Optimum

Ben Greenfield is a former Ironman triathlete, obstacle-course racer, author of Boundless, and host of the Ben Greenfield Life podcast. For more than a decade he has treated his own biology as an open lab: cold plunges, red light, Zone 2, peptides under medical supervision, and a daily supplement list he discusses on air and in print.

That list is useful because it is specific. Public roundups drawn from his podcast, Boundless, and bengreenfieldlife.com consistently name creatine, collagen peptides, a greens powder, omega-3s, vitamin D3 with K2, magnesium, a multi-strain probiotic, and adaptogens such as ashwagandha and reishi. He also treats morning coffee as a delivery vehicle (MCT oil, collagen, sometimes nootropics) rather than a caffeine hit.

This article is not an endorsement and X-Optimum has no affiliation with Greenfield or Kion. It is a catalog cross-reference: the compounds he has discussed in public, the biology that makes them interesting, and the X-Optimum products that occupy the same job.

1. Creatine: Phosphocreatine for Muscle and Brain

Greenfield's publicly listed daily creatine dose is about 5 g. That is the classic maintenance range after saturation. Creatine is stored as phosphocreatine in skeletal muscle and, in smaller amounts, in the brain. During high-intensity work, phosphocreatine donates a phosphate to ADP so ATP can recycle without waiting on oxidative phosphorylation.

That is why the compound shows up in both hypertrophy literature and cognitive work under sleep debt. It is not a stimulant. It is a phosphate buffer.

If you want that layer without a proprietary sports drink, Optimized Creatine Monohydrate ($21.99) is the straightforward monohydrate form. Mix it with water. Skip loading if GI tolerance is an issue; 3-5 g daily still fills the pool over a few weeks.

2. Collagen Peptides: Connective Tissue Amino Acids

Greenfield's public protocol often includes 10-20 g of collagen peptides daily, frequently in morning coffee. Collagen is not a complete muscle protein. It is glycine, proline, and hydroxyproline in a matrix that fibroblasts use when they are building tendon, ligament, skin, and cartilage.

If your training volume is high and your diet is mostly muscle meat, you can under-eat those residues. A collagen scoop is a targeted amino acid dump, not a whey replacement.

Grass-Fed Bovine Collagen Peptides Powder (Chocolate) ($24.99) maps to that slot. Stir it into coffee if you want the Boundless-style morning ritual. Keep a separate complete protein source for hypertrophy.

3. Morning Greens: Chlorophyll, Algae, and Travel Micronutrients

On travel days Greenfield has described a greens powder (he has named Organifi in interviews) as a fast way to get spirulina, chlorella, moringa, and some adaptogens when he cannot cook. He is explicit that powder is not a vegetable replacement. It is a convenience layer.

Spirulina and chlorella carry phycocyanin, chlorophyll, and a dense micronutrient profile. They also add a small prebiotic fiber load. That is useful when the rest of the day is airports and hotel protein.

Superfood Greens Formula ($19.99) is the X-Optimum analog: algae-forward greens rather than a candy-colored mix. Pair it with Superfood Reds Formula ($19.99) if you also want dietary nitrates from beetroot and berry polyphenols. Those are two different jobs.

4. Adaptogens: Ashwagandha, Reishi, and HPA Tone

Greenfield's public stack lists adaptogenic herbs in the morning and evening, including ashwagandha and reishi. Ashwagandha (Withania somnifera) is the one with the most human data on perceived stress and, in some trials, morning cortisol. Reishi sits more in the mushroom immunomodulation lane.

The mechanism is not "calm vibes." Withanolides appear to modulate HPA axis output. That matters if you train hard, sleep poorly, and still expect executive function at 2 p.m.

Ashwagandha and Shilajit Adaptogen Complex ($17.99) covers the ashwagandha side plus shilajit fulvic minerals. For a broader fungal layer, Optimized Mushroom Power Complex 10X ($17.99) or Fermented Mushroom Formula 6X ($39.99) is closer to a multi-species mushroom protocol than a single reishi capsule.

5. Probiotics: Multi-Strain Daily Coverage

Greenfield lists a multi-strain probiotic as a daily item. The rationale in his writing is gut barrier integrity and immune signaling, not a miracle weight-loss claim. Strain diversity matters more than a single CFU headline. Different Lactobacillus and Bifidobacterium species occupy different niches; a one-strain product is a narrower bet.

Optimized Super Probiotic ($17.99) is the catalog match for that daily coverage. Take it consistently. Do not expect a one-week personality change.

6. Magnesium, Sleep Pressure, and Evening Wind-Down

Greenfield treats sleep as training. Public summaries of his evening protocol include magnesium (often cited around 300-400 mg elemental), sometimes low-dose CBD, dim lights, and blue-light blocking. Magnesium is a cofactor in hundreds of enzymatic reactions, including those that quiet NMDA signaling and support muscle relaxation.

X-Optimum does not sell isolated magnesium glycinate. The sleep-adjacent tools in catalog are formula-based: Optimized Sleep Formula ($17.99) for an oral nighttime blend, and Better Sleep Strips ($17.99) if you want a faster oral-film format. Those are not 1:1 substitutes for elemental magnesium. They are sleep-architecture tools you can use alongside a separate magnesium product if your clinician wants a specific salt.

7. Coffee as Hardware, Not a Crash

Greenfield's morning coffee is Kion-branded in many interviews, with MCT oil and collagen added. The point he repeats is toxin load and function: coffee as a ketone-adjacent, collagen-carrying beverage, not a 400 mg caffeine bomb.

X-Optimum's closest functional coffees are Hemp Protein Fusion Coffee (Medium Roast) ($23.99) if you want plant protein in the cup, and Vitality Mushroom Fusion Coffee (Lion's Mane + Chaga) ($24.99) if you want fungal nootropics with the roast. Neither is Kion. Both treat the cup as a delivery system.

8. Cellular Energy: Where NAD+ Fits (and Where It Does Not)

Greenfield's Boundless-era writing spends time on mitochondrial output, red light, and NAD-related biology. He is more of a systems thinker than a single-pill NAD evangelist. If you still want a precursor or NAD+ capsule as an optional longevity layer, the catalog options are Optimized NMN ($19.99) and Optimized NAD+ ($21.99). Treat those as optional, not as the core of his published daily list.

A daily multinutrient floor is closer to his "every calorie should do a job" diet: Optimized Multivitamin ($17.99), or Optimum Male Multivitamin for Men ($17.99) if you want a male-formulated multi.

Omega-3 (3-4 g EPA/DHA) and vitamin D3 + K2 appear on his public list. X-Optimum does not currently sell a dedicated fish oil or D3/K2 SKU, so those stay as food or a third-party bottle. Do not force a greens powder to stand in for EPA.

Build Your Boundless-Style Stack at X-Optimum

Greenfield's protocol is too large to copy. The useful move is to steal the architecture: phosphate buffer (creatine), connective tissue amino acids (collagen), a greens layer when food is thin, HPA support (ashwagandha), gut flora, sleep protection, and a coffee that does more than spike adenosine antagonism.

Start with creatine and collagen if you train. Add greens and a probiotic if travel or diet quality is the bottleneck. Add ashwagandha if stress load is the limiter. Protect sleep last, because none of the daytime compounds compensate for a wrecked night.
