Always Tired? Discover the Real Fatigue Causes

Lack of Energy and Always Tired? The Real Fatigue Causes Might Surprise You

I had a solid routine and healthy habits, but something still wasn’t adding up.
I ate pretty clean.
I was consistent with intermittent fasting.
I had a regular stretching and yoga routine that helped me stay mobile and calm.

But despite all that… I still felt off.

My energy was low. My body ached. I was inflamed, constantly tired — and I couldn’t figure out why.

If you’re reading this, chances are you’ve been there, too — trying to do right, but not feeling right at all. Living with a lack of energy or feeling always tired.

That’s because what’s visible on the outside — your workouts, your diet, your mindful routine — is only half the story.

The other half? It's hidden beneath the surface.

When Yoga Isn’t Enough

As the founder of Tatago Yoga, a brand that creates extra-large, premium yoga mats designed for people who love to move freely and stretch their limits, I’ve always been a strong believer in the power of mindful movement.

Stretching. Slowing down. Listening to your body.
All of it is deeply important. Yoga helped me manage stress and sciatica, improve flexibility, and stay mentally clear. It absolutely made a difference in my life. I started a company because of it.

But despite my daily stretching routine, clean eating, and lifestyle habits — I was still running on empty.
And maybe you are too.

If you’ve been struggling with a lack of energy, if you feel like you're constantly tired even though you’re “doing the right things,” I want you to know: you’re not crazy, and you’re not alone.
The truth is, most people don’t realize that many fatigue causes are invisible — unless you test for them.

Fatigue Causes: What You Can’t See Can Still Hurt You

Here’s the problem with traditional healthcare:
Unless you’re clearly sick, most doctors won’t test beyond basic labs. They might tell you your bloodwork looks “normal.” But normal doesn’t mean optimal — and it definitely doesn’t mean you feel good.
There are dozens of potential causes of fatigue that don’t show up in standard tests:
•    Hormonal imbalances (like thyroid problems, low DHEA or testosterone)
•    Micronutrient deficiencies (magnesium, vitamin D, B12)
•    Inflammation
•    Lipid particle irregularities
•    Cortisol and stress-response dysfunction
None of those showed up on the standard panels I’d had done over the years. I’d gone to multiple doctors, mentioned my symptoms — and every time, I walked away without answers.

Then I happened to hear about biomarkers which led me to a company called Function Health.

The At-Home Health Test That Found What Doctors Missed

Function Health is a company that gives you access to 100+ clinical-grade biomarkers — the kind of blood testing you’d typically only get if you were seeing a specialist or had a serious illness.

Disclaimer:

I’m not in the business of promoting other business or things I don’t stand behind. I’ve used Function Health myself, and the insights it gave me were eye-opening. That’s why I can confidently say: if you’re struggling with low energy or unexplained fatigue, this might be the missing piece.

They look at:
• Hormones like DHEA sulfate, cortisol, and more

•    Heavy Metals (very important and the cause of numerous diseases)
•    Inflammation markers like CRP
•    All Nutrient levels including magnesium, vitamin D, and others
•    Lipid particle analysis (not just cholesterol — they break it down by type and size)
•    Organ health (heart, liver, kidney, thyroid)
•    And more

Their results weren’t just dumped into a confusing report — they were laid out clearly with explanations, lifestyle suggestions, and supplement recommendations backed by science.
It was the first time I got real answers.

What I Learned About My Own Fatigue Causes

When my results came in, I was shocked by what I found:
•    My DHEA sulfate was very low — a key hormone that helps regulate energy, mood, and resilience to stress.
•    My magnesium was low, even though I ate well AND took magnesium — this impacts muscle recovery, sleep, and brain function.
•    My LDL particle count was sky-high across the board — small, medium, and large particles — even though my total cholesterol was “normal”.
•    My PSA (prostate-specific antigen) was also unusually low, which no doctor had ever even looked at.
These weren’t random findings. They were the root causes of my fatigue. The reason I was inflamed. The reason my joints ached. The reason I had no energy, even after sleeping 8 hours.
And no standard doctor visit had ever uncovered it.

They gave me a clear, personalized health snapshot I could actually understand.

From Always Tired to Fully Alive — In Just Weeks

The dashboard laid out all my results — over 120+ biomarkers — with easy-to-read explanations, colorful charts, and specific guidance for what to do next. It was clean, intuitive, and surprisingly user-friendly.

One feature that really stood out? It told me my "biological age" — how my body was actually aging based on internal markers — not just my birthday. Seeing that number gave me a whole new level of motivation.

But here’s what I loved most:
I didn’t just get numbers — I got a plan, written and reviewed by real doctors.

Targeted supplement recommendations based on what my body needed (like ashwagandha and high-absorption magnesium)
Diet and lifestyle suggestions to help reduce inflammation
Recovery and stress-management tips that aligned with my current routine

And while it wasn’t an overnight miracle, I did start noticing real changes within a couple of weeks:

I had more sustained energy throughout the day.

My joint pain and inflammation started to ease.

I felt clearer — less foggy, more focused.

It was subtle at first. But the more I followed the recommendations, the more things started to shift.

For the first time in a while, I wasn’t just “managing” my fatigue — I was making progress.

What To Do If You're Always Tired (Even When You “Shouldn’t Be”)

If you're reading this because you're dealing with a lack of energy or trying to figure out your own fatigue causes, here’s what I recommend:

1. Start with movement — but make space for it.
Gentle yoga and stretching is a powerful way to reconnect with your body.
If you don’t already have a mat that lets you move freely, check out our Extra-Large Yoga Mats.
They’re supportive, durable, and built for real practice.

Also, to support others facing similar struggles, I’ve created a free guide with the simple stretches and routines that helped me feel better, reduce inflammation, and regain energy. It’s my gift to you — practical steps toward feeling like yourself again. It's free, just use the button below and i'll send it directly to your inbox.

2. Stop guessing. Start testing.
There’s no substitute for real data. If you're tired of being tired — or even if you feel fine — get your biomarkers checked. Because feeling okay doesn't always mean you're in the clear. Knowledge is power, and prevention? That’s priceless.

You don’t wait for the engine light to come on before checking your oil. Why do that with your body?

3. Give yourself time — and tools.
Health is a journey, and sometimes even with good habits, we lose our way. We feel off, tired, or inflamed — and we don’t know why.

Yoga helped me heal in ways I never expected. It eased my sciatica, reduced tension, and gave me the space to reconnect with my body. But even with all that progress, something still felt off — I was fatigued, inflamed, and couldn’t figure out why.

That’s where Function Health came in. It gave me the missing information: real data, expert guidance, and a personalized plan based on what was happening inside my body — not just what I could feel.

Final Thoughts: This Isn’t About Being Perfect. It’s About Feeling Whole.

You don’t have to do everything “right.”
You don’t have to be a wellness guru to feel good again.
You just need to listen to your body, move with intention, and get the right information to support your choices.

If you’re experiencing a lack of energy, if you’re always tired — don’t write it off as stress or age.

Get curious. Get tested.
Find out what's really going on.
Because once you know?
You can finally do something about it.
