I took this for about 6 months steadily and I feel like I'm back to normal. I only need it once in a while.

Is ThaenaBiotic® for You?
Most probiotics try to add a few lab-grown strains to a gut that contains trillions of microbes. Their effects are usually temporary and depend on constant use. ThaenaBiotic® delivers what your gut actually uses: the nutrient signals (postbiotics) that tell your body how to digest and regulate.
When your microbiome's been wiped out, your body loses access to key compounds that regulate digestion, energy, and mood. ThaenaBiotic® replenishes those microbial nutrients — safely, without live bacteria — helping your system remember how to balance itself.
If you can't tolerate certain foods, your microbes can't make the nutrients those foods would normally create. Our donors eat a full spectrum of healthy foods — so ThaenaBiotic® gives you the full spectrum of postbiotics. You get the nourishment your gut's been missing until you can reintroduce foods naturally again over time.
You track sleep. You track recovery. You fine-tune every system — except the one that runs them all: your gut. ThaenaBiotic® delivers the rare, human-native metabolites produced by the healthiest microbiomes on Earth. Think of it as molecular intelligence for high-functioning biology.
Still not sure? Talk to your healthcare provider about whether ThaenaBiotic® is right for you.
What's Inside
An Ecosystem, Not a Strain
ThaenaBiotic · Entire EcosystemCommercial Probiotic 1–10 Strains
We don't guess. We let healthy bodies formulate.
Every probiotic starts the same way. Scientists pick a strain they believe will help, grow it in a lab, and call it a formula. It's a guess — a well-intentioned one, but still a guess.
ThaenaBiotic® doesn't guess. It starts with real donors — people whose microbiomes have never been disrupted. Fewer than 1% of screened candidates qualify. What their healthy guts produce is sterilized and given to you. Not synthesized. Not engineered. Sourced.
The 10,000+ molecular signatures in ThaenaBiotic® aren't a formulation. They're what a working human microbiome actually makes.
You can't build a forest by planting the same tree over and over. We stopped trying.

So what, exactly, is in that ecosystem?
Postbiotics. Thousands of Them.
Short-Chain Fatty Acids
Fuel the cells that line your gut and support a healthy gut lining.
Peptides
Bioactive molecules that regulate gut barrier function, immune signaling, and inflammation response.
Indoles
Tryptophan-derived compounds that support mood pathways, gut barrier integrity, and immune tolerance.
Bile Acids
Secondary bile acids help calibrate immune tolerance and keep inflammatory signaling in check.
Ceramides
Lipid messengers that help provide cellular barrier support and repair, support metabolic health, and help maintain immune balance.
Amino Acids
Precursors to serotonin, dopamine, and other neurotransmitters your gut and brain both produce.
Thousands More
Science is still mapping them — but your gut already knows what to do with them.

Such an accessible way to feel better quickly- I thought I would need an FMT reboot but I’m grateful to have this seamless option- to get me through stressful times, flare ups, and travel - thank you to the wonderful scientists and donors.

I have been taking Thaena for over 2 years. I take it everyday. Can't imagine not taking it. For me it works better than a probiotic. Will continue to subscribe monthly. Feels like I am doing something good for my stomach.

Provider
We love this product for our clients going through gut health challenges!! Many have noticed an incredible difference!
Dr. Stephanie Raven
I am a healthcare provider and have been recommending ThaenaBiotic to my patients for the past several years. I have been very impressed with the product and recently decided to try it for myself. I am amazed at the improvement in my bowel movements after just a few short weeks...ThaenaBiotic is the only supplement I am taking at the moment - just 1 pill per day. I love how simple it is, rather than a complex protocol. Honestly, it's the best my bowel habits have been in years! I will definitely keep using ThaenaBiotic for myself, and recommending it to my patients.
Customer
Genius product and an absolute lifesaver for me!!! I'm so beyond grateful!!!
Dr. Dan Rubin
Now that you came out with this revolutionary postbiotic I can't not use it for people.
Customer
Thaenabiotic has been an absolute miracle for me. I was placed on antibiotics 6 times in less than 9 months and without this product my gut would have been trashed. I noticed a shift in my overall energy when I started it as well, my entire system got a boost. I am forever grateful for this product.
Provider
I am a huge fan of Thaena. Great product! It's been very beneficial for myself and for my husband. I often recommend it to clients.
Customer
Thaena has been a huge part of my recovery from GI problems. Nothing I've tried works like this.

This product is changing my life!
Dr. Amaliya Santiago
ThaenaBiotic has greatly changed my practice.
Customer
I started feeling some issues starting up so I am now back on it and am in my second month. Truly amazing results. Yes it is expensive but worth it. If you buy 3 months at a time you save $100.
Customer
I love this product and it was a lifesaver when I was recovering from antibiotics seven times in less than a year.
Customer
Hands down best gut healer ever!!!
Customer
Keeps me going.... comfortably... and rescues me when I go overboard..... thanks Thaena
Kim
I started taking it a few weeks ago and noticed improvement in my digestion (or post-digestion). I'm looking forward to seeing continued improvements.
MA
I don't honestly know if Thaena has helped me or not. I know it has caused me no harm. The principles and science behind it are good. I enjoy very much reading Thaena Fridays and have learned enough to keep wanting to take Unicorns (as they are called at my house). So I shall.
Victoria Sciarra
I have been impressed with the benefits of Thaena. Less bloating, belly pain, diarrhea and finally able to gain weight.
Diane Oktay
Very happy with results so far. Want to order more.
Carlynwright
Really impressed with how quickly this starts to work. I’ve become way more regular and feel like the quality of my BM’s has improved significantly. I will definitely be repurchasing
David Milroy
Great product!
Janice Healy
After taking two capsules a day for about 45 days, I actually slept for 7 hours per night without any sleep aids. Previous to using ThaenaBiotic I could not get any sleep at all unless I took melatonin and a cannabis product. I would call that a llife-saving miracle.
Marcos Pena
Helps with constipation in a way nothing else has.
Diana belden
I got this to try this out and I’m happy to say that it’s working! Thank you for this and i will reorder. Also customer service is stellar

With your provider
As directed
Doses above 2 capsules a day are for people whose healthcare provider has recommended them.
What to expect in the first days
ThaenaBiotic® can get things moving. Changes like gas or bloating in the first days can be transient; if it is uncomfortable, drop back to every other day or half a capsule and build up again slowly. If you experience increased diarrhea or heartburn, discontinue and talk with your healthcare provider. No need to taper: you can stop and restart whenever you like.
