Why You're Still Tired (Even After 8 Hours of Sleep) — And What Your Gut Microbiome Has to Do With It
Has this happened to you:
You go to bed early.
You get 7 or 8 hours of sleep.
You eat pretty well.
You might even take supplements.
And yet… you still feel drained.
Sound familiar?
If you’re constantly tired despite “doing all the right things,” you’re not broken!
The real reason you’re exhausted and fatigued might not have anything to do with your sleep...
🧠 ...it's your gut! Fatigue Isn’t Just a Sleep Problem — It’s Often a Gut Microbiome Problem
Your gut is like the power in your home — when it’s working right, everything flows. But if there’s a breakdown in the system, the lights go out… even if everything else seems in place.
Your gut microbiome is the same. It doesn’t just help you digest food — it controls how your body turns food into usable energy.
But if your gut bacteria are out of balance, your body may not be able to make or access that energy efficiently.
That means even when you're eating right and sleeping well, your body could still feel:
-
Groggy in the morning
-
Sluggish in the afternoon
-
Sore and drained after workouts
-
Mentally foggy or unmotivated
If your microbiome is off, your energy is off.
🚴♂️ The Fatigue Solution: "The Athlete Gut Microbiome Secret"
A 2019 study published in Nature Medicine by Harvard scientists made a groundbreaking discovery: Elite endurance athletes have more of a specific bacteria called Veillonella atypica.
Why does that matter?
Because this probiotic strain feeds on lactic acid — the same stuff that builds up in your muscles and causes fatigue — and converts it into propionate, a clean energy molecule your body can use.
That means the athletes weren’t just fit — their guts were turning fatigue into fuel.
“Elite athletes have fundamentally different microbiomes... it's not just training — it's biology.”— Dr. Peter Attia, MD -John Hopkins and Stanford trained Physician specializing in longevity and metabolic science.
🏃 That Harvard Discovery Changed Everything!
Meet Propionate: Energy From the Inside Out!
Scientists discovered that specific gut bacteria convert lactic acid (the stuff that makes you sore and tired) into a clean energy molecule called propionate.
🔬 How It Works, The: "Fatigue → Gut → Propionate → Energy" Cycle
- During exercise, your muscles create lactic acid.
- That lactate enters the bloodstream and makes its way to the gut.
- Gut bacteria like Veillonella atypica consume lactate.
-
In return, they produce propionate, which gets absorbed and used by your body as clean energy.
This isn’t theory. This is science published in Nature Medicine and backed by Harvard researchers.
🚪 Most People Think Energy Comes Only From Food or Caffeine.
But this is a fuel source already inside you that almost nobody is talking about: propionate!
Propionate is a type of short-chain fatty acid (SCFA) produced in your gut by specific bacteria. And here's what makes it fascinating: it's not just a digestive byproduct. Your body can actually use it as fuel.
Recent research shows that propionate:
- powers cells,
- boosts endurance, and
- even improves recovery!
You don’t need to be an elite marathon runner like the one's in the Harvard scientific study to benefit from propionate.Thanks to Fitbiomics, this groundbreaking probiotic technology now works for everyday people like us!
- Sick of caffeine crashes? Propionate offers consistent, natural energy.
- Training regularly? Propionate can support faster recovery and VO2 max.
- Feeling drained even after sleep? A healthy gut producing propionate could be your solution.
And it all starts with your microbiome — particularly a strain called Veillonella atypica, found in the guts of elite athletes.

🚫Bad Solutions: "Energy Drinks and Coffee Don’t Fix Fatigue"
When we’re tired, we reach for caffeine, sugar, or quick-fix supplements.
But these only cover up the problem.
- Coffee spikes your energy — then crashes you later
- Energy drinks stress your adrenals and mess with sleep
-
Pre-workouts wear off fast and don’t fix your baseline energy
V•Nella addresses energy at the root by improving how your gut processes lactic acid — not just masking fatigue.
No caffeine. No crash. Just real, microbiome-powered performance.
