Rich Roll is not a typical fitness influencer. He is a Stanford-educated lawyer turned ultra-endurance athlete who completed the EPIC5 Challenge — five Ironman-distance triathlons on five Hawaiian islands in under a week — entirely on a whole food plant-based diet. He is the author of Finding Ultra, host of one of the most-listened-to wellness podcasts on the planet, and a Momentous-sponsored athlete whose approach to supplementation is as methodical and evidence-driven as his training.
Rich has been public about his supplement protocol across his podcast, through his Momentous partnership (spotlighted by Momentous in February 2025), and via guests on the Rich Roll Podcast who have helped him and his audience understand the specific nutritional gaps that plant-based athletes face. His stack is built on one framework: whole food first, supplement only to correct what diet cannot reliably deliver, and use only compounds with robust clinical backing.
Below is a breakdown of every compound Rich Roll uses and advocates for — the mechanism behind each one, and where X-Optimum carries the equivalent.
1. Vitamin B12 — The Non-Negotiable for Every Plant-Based Athlete
Rich Roll has stated explicitly — and repeatedly on his podcast — that Vitamin B12 is the one supplement that every person following a whole food plant-based diet must take without exception. It is not optional, not debatable, and not something that any plant food reliably provides at adequate levels.
The mechanism explains why. Vitamin B12 (cobalamin) is synthesized exclusively by microorganisms. It is found in meaningful quantities only in animal products — meat, fish, dairy, eggs — because those animals have consumed microorganisms or absorbed B12 through their gut bacteria. Plants do not contain B12, and the trace amounts found in certain fermented foods or algae are largely in an inactive form (pseudovitamin B12) that does not bind to intrinsic factor and is not absorbed through the ileum.
Deficiency is progressive and severe. B12 is required for myelin sheath synthesis — the fatty insulation surrounding nerve axons that enables rapid signal transmission. It is also a cofactor for methionine synthase, the enzyme that regenerates methionine from homocysteine. Without adequate B12, homocysteine accumulates — a direct cardiovascular risk marker — and neurological degradation begins at the cellular level, often without obvious early symptoms until damage is significant.
For an ultra-endurance athlete whose neuromuscular efficiency and cardiovascular health are performance fundamentals, B12 deficiency is not an abstract risk. It is a performance ceiling.

→ Cognitive Support Multivitamin — $17.99 (methylated B-vitamin complex including B12 and B6 for neurotransmitter synthesis and homocysteine clearance)
2. Vitamin D3 — The Hormonal Foundation No Plant Food Covers
Rich Roll lists Vitamin D as a core daily supplement for anyone not receiving consistent, direct sun exposure of at least 20 minutes per day. He has discussed it across his podcast in the context of immune function, bone density, hormonal regulation, and athletic recovery — all areas where Vitamin D's role is well documented and where deficiency silently degrades performance.
Vitamin D3 (cholecalciferol) is technically a prohormone — upon conversion to its active form calcitriol in the kidneys, it binds to the Vitamin D receptor (VDR) found in virtually every tissue in the body and regulates over 200 genes. These include genes governing calcium and phosphate absorption (bone matrix maintenance), T-cell and B-cell proliferation (immune response), and muscle protein synthesis. For athletes specifically, low Vitamin D is associated with increased injury risk, impaired muscle recovery, and elevated inflammatory markers post-exercise.
Plant-based sources of Vitamin D (primarily D2 in mushrooms) are significantly less bioavailable than D3, and sun-derived synthesis is unreliable across latitudes, seasons, and skin types. Supplementation is the only consistent solution.

3. Algae-Based Omega-3 DHA/EPA — The Plant-Based Solution to the Conversion Problem
Rich Roll has discussed Omega-3 supplementation specifically in the context of plant-based eating, and his position is precise: fish oil is not the answer for plant-based athletes — algae oil is. This is not a marketing distinction. It reflects a genuine gap in how plant-based diets supply long-chain omega-3 fatty acids.
The issue is the ALA-to-EPA/DHA conversion rate. Plant foods (flaxseed, chia, walnuts, hemp) provide ALA (alpha-linolenic acid), a short-chain omega-3. The body must convert ALA to EPA and then to DHA through a multi-step enzymatic process — but human conversion efficiency is notoriously low: approximately 5–10% of ALA converts to EPA, and less than 1% converts to DHA. For an athlete with high metabolic and neurological demands, relying on conversion alone to meet DHA and EPA requirements is insufficient.
DHA is a primary structural component of neuronal membranes, governing synaptic plasticity and neurotransmission efficiency. EPA is the dominant anti-inflammatory omega-3, competing with arachidonic acid at COX and LOX enzyme sites to shift the eicosanoid balance toward pro-resolving, anti-inflammatory signaling. For an ultra-endurance athlete managing the inflammatory load of extreme training volumes, EPA's role in recovery is direct and measurable.
Algae oil delivers pre-formed EPA and DHA — bypassing the conversion problem entirely and delivering the same compounds found in fish oil (fish themselves get DHA and EPA from algae they consume). X-Optimum's Hemp Protein Fusion Coffee delivers plant-based omega-3 fatty acids alongside a complete amino acid protein matrix — providing daily ALA from hemp alongside protein, forming the dual cornerstone of a plant-based athlete's morning nutrition.

4. Creatine — What Rich Roll Calls the Most Underrated Plant-Based Supplement
Rich Roll has discussed creatine multiple times across his podcast and through his Momentous partnership — consistently noting that plant-based athletes are the population that benefits most from creatine supplementation, precisely because they are the most creatine-depleted.
The reason is dietary. Creatine is found almost exclusively in animal muscle tissue — particularly red meat and fish. Omnivores accumulate creatine through diet and maintain muscle phosphocreatine stores at or near saturation. Plant-based athletes start from a lower baseline: research consistently shows that vegans and vegetarians have significantly lower muscle creatine stores than meat-eaters, meaning the incremental benefit of supplementation is proportionally larger for plant-based populations.
The mechanism is well established. Creatine phosphate donates a phosphate group to ADP to regenerate ATP during the phosphocreatine energy system — the rapid power source activated in the first 10–30 seconds of maximal effort. For an ultra-endurance athlete, this translates to faster sprint capacity, improved lactate clearance at high intensities, and faster recovery between high-output intervals. The cognitive benefits — neuroprotection under mental fatigue, improved working memory, and reduced cognitive degradation under sleep deprivation — are increasingly documented and particularly relevant to the mental demands of multi-day endurance events.

5. Plant-Based Protein — Fueling Repair at the Volume Rich Roll Trains
Rich Roll's approach to protein is plant-forward by design, and he has discussed it extensively — both in terms of adequacy for elite endurance performance and as a philosophical cornerstone of his whole food plant-based framework. His Momentous partnership includes plant-based protein as a daily recovery tool.
The critical variable for endurance athletes is leucine — the branched-chain amino acid that acts as the primary molecular trigger for mTORC1 activation and muscle protein synthesis. Plant proteins are generally lower in leucine per gram than whey, which means plant-based athletes must either consume larger total quantities of plant protein or strategically combine sources to ensure leucine sufficiency. Hemp protein is a notable exception: it delivers a complete amino acid profile including all essential amino acids with meaningful leucine content, alongside beneficial omega-3 fatty acids and fiber — making it a practical daily protein vehicle for plant-based athletes.
At the training volumes Rich Roll operates at, protein timing and completeness are not secondary concerns. Muscle protein synthesis rates are elevated for 24–48 hours post-endurance effort, and adequate amino acid availability throughout that window directly governs the quality of recovery.

6. Functional Mushrooms — The Adaptogenic Performance Compounds Rich Roll Champions
Rich Roll has featured some of the world's leading mycologists and functional medicine practitioners on his podcast — including Paul Stamets, the world's foremost mycologist — and has discussed functional mushrooms as a category of plant-based performance compounds with serious clinical underpinning. His advocacy covers both the endurance performance applications (Cordyceps) and the cognitive and immune applications (Lion's Mane, Chaga, Reishi).
Cordyceps sinensis is the endurance athlete's mushroom. Its primary active compounds — cordycepin and adenosine — directly stimulate ATP biosynthesis and increase VO2 max by improving oxygen utilization efficiency. Clinical research shows Cordyceps supplementation increases maximal oxygen uptake and reduces the oxygen cost of submaximal exercise — two metrics that translate directly to endurance performance at elite training volumes.
Lion's Mane (Hericium erinaceus) produces hericenones and erinacines — small lipophilic compounds that cross the blood-brain barrier and stimulate Nerve Growth Factor (NGF) synthesis. NGF governs neuronal maintenance, synaptic plasticity, and the integrity of the cholinergic system. For a podcast host who operates at the intersection of elite physical performance and high cognitive output, Lion's Mane targets the biological substrate of both.
Chaga (Inonotus obliquus) delivers one of the highest ORAC (Oxygen Radical Absorbance Capacity) values of any natural compound — providing systemic antioxidant coverage against the oxidative stress generated by extreme training volumes. Its betulinic acid compounds also interact with Dectin-1 immune receptors, modulating innate immune activity and inflammatory signaling.

→ Optimized Chaga Mushroom — $21.99 (standalone antioxidant immune support)
→ Fermented Mushroom Formula 6X — $39.99 (fermented for enhanced bioavailability)
7. Greens and Superfoods — Micronutrient Density at Scale
Rich Roll discusses greens supplementation as a practical tool for ensuring micronutrient density on high-training days when caloric demand is extreme and food volume alone cannot guarantee coverage of every micronutrient. His plant-based framework already emphasizes vegetable diversity, but concentrated greens formulas provide phytonutrient depth — polyphenols, flavonoids, carotenoids, chlorophyll — that even a well-designed plant-based diet may under-deliver at the required dosages.
For endurance athletes, this has a specific application: polyphenols (particularly quercetin, resveratrol, and anthocyanins) directly modulate NF-κB inflammatory signaling pathways, support mitochondrial biogenesis via PGC-1α activation, and reduce exercise-induced oxidative damage — mechanisms that translate into faster recovery, reduced DOMS, and sustained training adaptability over long competitive seasons.

→ Superfood Reds Formula — $19.99 (antioxidant-rich berry and reds complex — anthocyanins, quercetin, resveratrol)
8. NAD+ and Longevity — The Cellular Energy Conversation Rich Roll Takes Seriously
Rich Roll has hosted multiple leading longevity researchers on his podcast — including conversations centered on NAD+ biology, NMN supplementation, and the cellular mechanisms of aging. His approach to longevity is characteristically rigorous: he discusses these compounds in terms of their mechanisms and evidence base, not as miracle molecules, but as tools that target real biological degradation pathways.
NAD+ (Nicotinamide Adenine Dinucleotide) declines progressively with age — by approximately 50% between age 40 and 60. As a cofactor for sirtuins (SIRT1–7, the longevity proteins that govern DNA repair, mitochondrial biogenesis, and inflammatory gene expression) and for PARP enzymes (which repair DNA strand breaks), NAD+ depletion directly impairs the cellular maintenance systems that govern both longevity and athletic recovery capacity. NMN (Nicotinamide Mononucleotide) is a direct NAD+ precursor that crosses cell membranes and raises intracellular NAD+ levels efficiently.
For a 57-year-old ultra-endurance athlete whose training volumes impose significant oxidative and metabolic stress, NAD+ replenishment is not purely a longevity play — it is a recovery and mitochondrial efficiency intervention.

→ Optimized NAD+ — $21.99 (direct NAD+ with Quercetin and Resveratrol — sirtuin activator complex)
→ Optimized Resveratrol — $19.99 (SIRT1 activator / caloric restriction mimicry / polyphenol longevity compound)
9. Magnesium and Sleep — Recovery Is Where Adaptation Happens
Rich Roll discusses sleep with the same seriousness he brings to training — as the primary biological window during which the adaptations from hard work are actually consolidated. His Momentous partnership and podcast content both reflect a deep understanding that sleep deprivation suppresses growth hormone release, impairs muscle protein synthesis, elevates cortisol, and blunts the immune response — all of which directly undermine training capacity at the volumes he operates.
Magnesium deficiency is widespread even among athletes who eat well, because training dramatically increases magnesium excretion via sweat and urine, and most Western diets fail to replace it. Magnesium is a cofactor in over 600 enzymatic reactions and plays a specific role in sleep architecture by activating NMDA receptors in a modulatory capacity and supporting GABA-A receptor signaling — the primary inhibitory system governing neural calming and sleep onset. Adequate magnesium also reduces nocturnal cortisol, which further improves sleep quality and anabolic hormone balance.

→ Optimized Sleep Formula — $17.99
10. Adaptogens — Stress Resilience for the Long Game
Rich Roll has discussed the physiological and psychological demands of ultra-endurance training extensively — not just the physical stress of multi-hour workouts, but the cumulative neuroendocrine load of sustained overreaching. He frames stress management not as a wellness concept but as a biological performance variable: chronically elevated cortisol suppresses testosterone, impairs recovery, degrades sleep quality, and elevates systemic inflammation — all of which directly limit training adaptability.
Ashwagandha (KSM-66 extract) is the most clinically validated adaptogen for HPA axis regulation. Multiple peer-reviewed randomized controlled trials show significant reductions in serum cortisol, improvements in VO2 max, increases in testosterone, and improvements in sleep quality with consistent KSM-66 supplementation. For an ultra-endurance athlete managing the long-term hormonal consequences of high training stress, ashwagandha addresses the cortisol-testosterone-recovery axis directly.
Shilajit — a mineral-rich adaptogenic resin from high-altitude geological formations — delivers over 85 ionic trace minerals and fulvic acid, a molecular electron shuttle that enhances mitochondrial electron transport chain efficiency. Combined with ashwagandha, it targets both the neuroendocrine stress axis and the mitochondrial energy production system simultaneously.

→ Ashwagandha and Shilajit Adaptogen Complex — $17.99
11. Gut Health — The Microbiome as Performance Infrastructure
Rich Roll's whole food plant-based diet is inherently microbiome-supportive — high fiber, diverse phytonutrients, fermented foods — but he has discussed gut health on his podcast as a foundational system that governs far more than digestion. The gut microbiome produces short-chain fatty acids (SCFAs) that maintain gut barrier integrity, modulate systemic immune activity, and influence blood-brain barrier permeability. Dysbiosis — microbiome imbalance — elevates systemic inflammation, impairs nutrient absorption, and degrades immune resilience.
For an endurance athlete, gut health has an additional layer of specificity: intense endurance exercise transiently increases gut permeability ("leaky gut") due to splanchnic vasoconstriction during prolonged effort, allowing bacterial lipopolysaccharides (LPS) to enter systemic circulation and trigger inflammatory cascades. Multi-strain probiotic supplementation helps maintain gut barrier integrity and support the microbial diversity that buffers against this exercise-induced permeability.

Build Rich Roll's Plant-Based Performance Stack at X-Optimum
Rich Roll's supplement protocol is built around a single principle that he has articulated clearly across years of podcasting: supplement what your diet cannot reliably provide, use only what the science supports, and treat your biological systems as the infrastructure that everything else — your training, your cognition, your longevity — runs on.
For a plant-based athlete, that means correcting the specific gaps that a whole food plant-based diet leaves open: B12, Vitamin D, long-chain omega-3s, and creatine — then building outward into functional mushrooms, longevity compounds, recovery support, and adaptogenic stress management. Every compound in that framework maps directly to the X-Optimum catalog.
