Dave Asprey · The Human Upgrade
The probiotic Dave Asprey takes.
You can eat perfectly and still lose if your gut can't do its job. Just Thrive is the spore-based probiotic Dave takes — clinically shown to arrive 100% alive in your gut, with one strain studied to produce antioxidants right where your body absorbs them.†
- Arrives 100% alive. Spore-based strains survive stomach acid, up to 1,000× better than ordinary probiotics.†
- Four clinically-studied strains. Each one is named and each has a job, with no proprietary blend.
- 15 antioxidants, made in your gut. The patented HU36® strain produces them right where your body absorbs them.†
- Shelf-stable & third-party tested. No refrigeration, no fillers, no junk.

More than a probiotic: the complete gut stack that makes everything else work
Your subscription doesn't just come with the probiotic Dave takes. He's adding his Digestive Bitters too — the second piece of the gut puzzle. When your gut absorbs better, every other investment you make in your health starts paying off more.
Why you'd want them, not just why they're free
Digestive Bitters are a blend of 12 clinically-studied bitter herbs in a smart, taste-free capsule. Taken with your largest meals, they wake up your body's own digestion, so food breaks down comfortably, your body absorbs more of what you eat, and you skip that heavy, over-full feeling after a big meal.†
- Eases after-meal heaviness: support against the bloated, over-full feeling.†
- Helps you absorb what you eat: bitters prime your gut to put nutrients to work.†
- Taste-free capsule: all the upside of traditional bitters, none of the bitter taste.
Most probiotics never make it. Ours arrives alive.
