The wellness world has spoken: gut health isn’t just trending, it’s transforming how we think about total body optimization. From Dave Asprey’s supplement stacks to Nicole Berrie’s Chi-flowing protocols, today’s leading biohackers are proving that digestive health is the foundation of feeling unstoppable.
But here’s what’s fascinating: while they all agree on the importance of optimizing digestion, their approaches couldn’t be more different. Let’s dive into what’s actually working and what you might be missing.
But first, let’s remember:
Digestion doesn’t end in the stomach; it culminates in absorption, the point where nutrients actually enter the bloodstream and become usable energy, hormones, and cellular fuel. You can eat the cleanest food or take the most advanced supplements, but if your gut lining is inflamed or your enzyme activity is low, those nutrients pass right through you. True optimization isn’t about consumption, it’s about assimilation. Supporting absorption through enzymes, healthy bile flow, and a balanced microbiome turns nutrition into transformation.
The Great Digest Debate: Three Philosophies, One Goal
Dave Asprey: The Supplement Maximalist
The “Father of Biohacking” doesn’t mess around when it comes to digestive optimization. Asprey’s daily protocol includes digestive enzymes (brands like NOW Super Enzymes and MassZymes), betaine HCl with pepsin before larger meals, and multiple strains of Omni-Biotic probiotics taken on an empty stomach.
Asprey also emphasizes that prebiotics have a longer-lasting effect on gut health than probiotics alone, which is why he formulated InnerFuel Prebiotic, mixing it right into his famous Bulletproof coffee. During fasting periods he recommends proteolytic enzymes like serrapeptase and nattokinase, as these can help break down scar tissue and waste proteins in the blood when there’s no food to digest.
His philosophy? Your gut is under constant assault from modern life, and you need serious supplementation to fight back.
Nicole Berrie: The Energy Flow Optimizer
Bonberi’s founder takes a completely different angle: “MOTION in your life, physically and spiritually” through food combining and maintaining Chi (energy) flow. While she does alternate between three different probiotic supplements (Renew Life, Metagenics, and Dr. Ohira), her real secret weapon is traditional fermented foods and strategic eating patterns:
Food combining principles to optimize digestion naturally
Raw foods until dinner to provide enzymes and alkalinity
The Bonberi approach proves you don’t need to pop 20 pills a day. But you do need to be intentional about how and when you eat.
Digestion isn’t just what you swallow. It’s also what your body clears, how you support your energy system, and how you live.
Joe Holder: The Minimalist’s Mentor
Nike Master Trainer Joe Holder keeps it surprisingly simple. His go-to is an “immunity digestion potion” featuring ginger, cayenne and adaptogens like ashwagandha and reishi mushrooms. No complex protocols, no supplement schedules. Just real food doing real work.
Recommends ginger to chew in food form as per connection between the parasympathetic nervous system and digestion.
The Herbal Intelligence: Nature’s Original Digestive Hack
Before the AI-driven stacks and high-tech enzymes, nature already held the blueprint for optimal digestion. In 2025, the next generation of biohackers is turning back to these ancient plant allies - bridging the gap between herbal wisdom and performance science.
Here are the standout botanicals and enzymes leading the digestive revolution:
Bromelain & Papain
These pineapple- and papaya-derived enzymes are nature’s most effective protein digesters. Bromelain breaks down complex proteins and reduces post-meal inflammation, while Papain enhances nutrient absorption and relieves bloating. Together, they mimic the body’s natural enzyme activity without overstimulating it.
Dandelion Root Extract
A hero for liver and bile function, dandelion root stimulates digestive juices, supports detoxification, and helps regulate appetite. Its mild diuretic properties also help eliminate waste and water retention, leaving you feeling lighter and more energized.
Ginger Extract
A classic in Ayurvedic and TCM traditions, ginger improves gastric motility and reduces sluggishness. It’s also a powerful anti-inflammatory that soothes the gut lining and supports the gut-brain axis. A complete reset.
Lemon Balm Extract
Known for calming both the mind and the stomach, lemon balm helps relax intestinal spasms and ease tension-related digestive discomfort. It’s the ultimate dual-action herb for anyone whose digestion is easily thrown off by stress.
Artichoke Extract
This extract promotes bile flow and liver detoxification, aiding fat metabolism and helping regulate cholesterol. It’s particularly valuable for those with slow digestion or that heavy, full feeling after meals.
These herbs don’t override the body’s natural processes; they enhance them. In an era where most digestive systems are overstressed and undernourished, plant-based intelligence is the ultimate biohack.
The Non-Negotiables: What They ALL Agree On
Despite their different philosophies, there are three digestive essentials that every major biohacker swears by:
1. Probiotics Are Not Optional
Whether through supplements or fermented foods, maintaining bacterial balance is universally recognized as crucial. The debate isn’t whether you need probiotics—it’s how to get them most effectively.
2. Digestive Enzymes Matter More Than You Think
As BiOptimizers explained on Asprey’s podcast, enzymes do about 25,000 different functions in the body—“everything from thinking to blinking.” Even minimalists like Holder rely on natural enzymes from raw and fermented foods.
3. Stress Is Your Gut’s Worst Enemy
Digestive experts agree: “The single biggest dysfunction that impacts digestion is stress.” This is why adaptogens and magnesium appear in nearly every protocol—they’re not luxury additions, they’re gut essentials.
The 2025 Game-Changers
This year’s breakthroughs are pushing the boundaries of digestive optimization:
Bioregulators: Once used by Soviet researchers, these peptide compounds are now being studied for their ability to restore balance to specific organ systems—including the gut.
AI-Personalized Protocols: Advanced health-tracking platforms now analyze your biometrics and meal patterns to tailor supplement timing and dosages in real time.
Synergistic Stacking: The “take a probiotic” era is over. The future is stacking—combining probiotics, prebiotics, enzymes, and herbal extracts in formulas designed for synergy and efficiency.
The Million-Dollar Question: What Should YOU Take?
Here’s the truth: the biohacking market is projected to reach $108.57 billion by 2029, and digestive health is leading that charge. But throwing money at random supplements isn’t the answer.
The winning 2025 formula combines:
Multi-strain probiotics (10+ billion CFU)
Digestive enzymes (including plant-based sources like bromelain and papain)
Prebiotic fiber (to feed your good bacteria)
Adaptogens & calming herbs (to neutralize the stress-gut connection)
Targeted support (like betaine HCl for protein digestion or artichoke extract for bile flow)
Your Next Move
The evidence is clear: whether you follow Asprey’s maximalist approach or Holder’s minimalist path, digestive optimization is non-negotiable for peak performance in 2025.
The smartest biohackers are integrating both. They’re not following one guru blindly they’re blending the best of every philosophy and personalizing it.
Start with high-quality basics. Build slowly. Track how you feel. Because as every modern biohacker knows:
You’re not what you eat—you’re what you digest and absorb.
