The Human Upgrade: Biohacking for Longevity & Performance
Episode 1441: "Your Organic Protein Powder Is Slowly Killing You"
Host: Dave Asprey
Guest: Oliver (Founder of Puori)
Release Date: March 31, 2026
Overview
This episode dives into the murky realities behind the supplement industry, zeroing in on hidden dangers in protein powders and foundational supplements. Host Dave Asprey and guest Oliver, founder of Puori, blend decades of biohacking experience with firsthand knowledge of supplement manufacturing and quality control. They reveal how even premium organic and plant-based powders can harbor toxins and heavy metals, and they outline what truly matters when choosing supplements for health, longevity, and performance.
Key Discussion Points and Insights
1. Supplements: Foundation vs. Hype
[02:15]
- Dave and Oliver stress the importance of foundational supplements (e.g., vitamin D, magnesium, omega-3, creatine) over trendy, “sexy” new compounds.
- Oliver: “There’s a lot of incredibly sexy new stuff on the market... but I absolutely take the foundational supplements first.”
- Both agree: real food, sleep, and lifestyle come before supplements.
2. Omega-3 Index—Why Fish Oil Quality Matters
[04:31]
- Omega-3 index measures EPA and DHA in red blood cells; optimal is ~8%, Americans average 4–5%.
- Vegan omega-3 sources are inefficient: “It takes 45 grams of vegan omega-3s to make one gram of DHA in your body, if your body can convert it, which it won't unless it has foundational supplements present.” (Dave, 05:42)
- Rancid (oxidized) fish oils can cause inflammation rather than fight it.
- Oxidation scores (totox): Puori aims for levels below 10—“industry best” compared to many brands tested.
3. Lab Testing, Batch Transparency, and Oxidation
[07:37], [09:36], [11:01]
- Most brands don’t test every batch; many only test raw materials, not the finished product.
- Puori uses QR codes on every batch for full transparency.
- Room temperature storage is okay if shielded from sunlight; overheating during shipping is a major risk (“Sun-baked fish oil is a very bad thing.” —Oliver, 16:35).
4. Contaminants in Supplements & Protein Powders
[34:07], [34:46], [36:37]
- Heavy metals are rampant in plant-based protein powders—often 5–10x higher than whey.
- Organic does not equal low in heavy metals—sometimes it’s higher!
- Dave: “It’s a trade-off: do you want healthy, flavorful cacao that has more metals, or low-quality cacao with less metals?” (42:54)
- Greenwashing risks—e.g., “gluten-free fish oil” labels are as pointless as “gluten-free water.”
5. The Economics of Purity & Industry Challenges
[32:29], [33:12], [36:58]
- Testing and rejecting contaminated batches costs brands substantially.
- Some ethical companies (like Puori) discard 5% or more of raw ingredients to assure purity—even when third parties accept them.
- Strict standards (like California’s Prop 65) are controversial; sometimes scientifically sensible, sometimes driven by politics or industry lobbying.
- Dave: “You’re always doing this dance between how do we make it even better and how do we make it affordable?”
6. Deep Dive: Protein Source Matters
[57:12], [59:39]
- “Milk is relatively safe in terms of toxins… if you overeat this one plant, you will have weaker babies, you’ll have less babies, and then the plants can grow.” —Dave (58:46)
- Plant proteins (especially brown rice, pea, etc.) have higher heavy metal loads than animal-based (whey or collagen) proteins.
- “Plant protein is cheaper and it’s not a superfood. It just isn’t.” —Dave (59:39)
7. Collagen and Glyphosate
[61:01], [62:29]
- Glyphosate accumulates in animal collagen; organic/grass-fed sources are critical.
- Dave: “If you’re eating non grass-fed collagen protein you’re getting a dose of glyphosate… and you’re going to get glyphosate in your collagen infrastructure.”
- Puori tests every batch and publicly posts results for glyphosate and pesticides.
8. Creatine: A Rising Foundation Supplement
[46:22], [49:14], [50:22]
- Creatine is essential for not just muscle health but brain health (e.g., concussion recovery)
- Anecdotes: Both Dave and Oliver share personal stories of creatine aiding in post-concussion cognitive recovery.
- Creatine is becoming broadly recognized for benefits beyond bodybuilding.
9. Heavy Metals and Real-World Detox
[44:24], [45:07]
- Testing heavy metals in the body is complex; chronic exposure is unavoidable.
- “Avoiding it in your food as much as you can and probably taking some detoxing things on a regular basis to help shed something that’s unavoidable.”
Notable Quotes & Memorable Moments
On Plant vs. Animal Protein:
“Plants are the highest toxin, so animals won’t eat it… That’s why plant protein is cheaper and it’s not a superfood. It just isn’t.”
—Dave Asprey [59:39]
On Industry Transparency:
“If you’re not testing every single batch, you’re not providing the transparency that consumers today deserve.”
—Oliver [10:46]
On Vitamin D Deficiency:
“The darker your skin, the more likely you are to have vitamin D deficiency. And the more you live in northern Europe, the more likely you are because there’s no sunshine.”
—Dave Asprey [17:46]
On Regulatory Standards:
“When’s the last time a government ever made an optimal health recommendation, ever? They’re economics based.”
—Dave Asprey [24:14]
On Supplement Labeling:
“It’s like saying gluten free fish oil… gluten free tomatoes and whatnot in store. Gluten free water.”
—Dave Asprey [31:14]
On the Economics of Purity:
“You and I, we want to sell it for $1 because I want everyone to have it. And we also want to pay more than $1 for testing so that we know that what we’re selling is pure.”
—Dave Asprey [63:42]
On Founders’ Motivation:
“A lot of founders of companies, we have a reason for doing this. For me, I don’t want anyone to have the kind of fibromyalgia and chronic fatigue and brain fog… It was just a lack of… distribution of knowledge.”
—Dave Asprey [55:22]

Final Takeaways
- Quality control and testing are non-negotiable. Good brands will test every batch and make results public, even at increased cost.
- Plant-based protein isn’t inherently “better”—sometimes it’s a Trojan horse for heavy metal exposure.
- Collagen and fish oils are only as clean as their source. Industrial feed = higher toxins.
- Creatine is no longer just for athletes—it’s a brain health essential.
- Don’t trust the label—trust the data. Transparency is your only safeguard in the supplement market.
- Biohacking is about knowledge, not just products. Empower yourself with information to make better choices for longevity and performance.
