Methylation & MTHFR panel
MTHFR genetics, homocysteine, methylmalonic acid, B12, and folate — to see whether your methylation cycle can actually produce energy, neurotransmitters, and detox capacity.
Chronic Fatigue · Long COVID · Brain Fog · Sleep
A root-cause program for chronic fatigue, brain fog, post-viral / long COVID recovery, and unexplained exhaustion. Functional testing your regular doctor doesn't run — and treatments most primary care offices don't offer. In Kennewick, WA.
You might be here because…
Waking unrefreshed. Afternoon crashes. That heavy, wrung-out feeling that doesn't lift even after a weekend off.
Long COVID. Post-viral fatigue. Post-mono. The feeling that a virus flipped a switch and you never came back to baseline.
CBC normal. TSH normal. Ferritin low but “fine.” You know something is wrong. You need a workup that goes further than the standard panel.
Our philosophy
Chronic fatigue almost always has a mechanism — often several stacked on top of each other. Mitochondrial dysfunction. Poor sleep architecture. Chronic viral activation. Hormone imbalance. Methylation blocks. Gut inflammation. Cortisol dysregulation. Standard labs miss most of them. We use functional testing to find what's actually broken, then rebuild it in the right order.
Functional labs go beyond a normal CBC and TSH. Methylation, DUTCH cortisol, MRT food sensitivity, gut microbiome, and mitochondrial markers change what we treat.
Sleep and mitochondrial cofactors first. Hormones and gut second. Advanced therapies (ozone, IVs, peptides) once the foundation is set. Skipping steps wastes months.
Validated symptom scales (fatigue, sleep, post-exertional malaise), wearable data, and repeat labs measure whether the plan is actually working.
The mitochondrial framework
Mitochondria are the tiny power plants inside every cell. When they underperform — from oxidative stress, nutrient depletion, infection, medications, or toxin exposure — every system that runs on ATP falters. Muscles fatigue. Brains fog. Immune systems misfire. Fixing the roots means giving mitochondria what they need (cofactors, oxygen, low inflammation) and removing what's stressing them.
The root-cause workup
Every test is optional. Your workup is a subset chosen from your intake.
MTHFR genetics, homocysteine, methylmalonic acid, B12, and folate — to see whether your methylation cycle can actually produce energy, neurotransmitters, and detox capacity.
Full sex hormone panel plus a 4-point cortisol rhythm — critical for understanding fatigue, sleep disruption, and adrenal contribution.
Mediator Release Test identifies foods driving low-grade inflammation. Often the missing piece in patients with unexplained fatigue and gut symptoms.
Comprehensive stool analysis: pathogens, dysbiosis, gut inflammation markers (calprotectin, secretory IgA), and digestive function.
hs-CRP, ferritin, homocysteine, HbA1c, insulin, ApoB, and a full lipid panel — inflammation and insulin resistance are silent fatigue drivers.
EBV, CMV, HHV-6, and Lyme co-infection screening when indicated. Viral reactivation is one of the most-missed causes of chronic fatigue.
Therapeutic pillars
Choose from the toolkit — your plan is built from the pieces that fit your case.
Medical ozone modulates the exact biology that fails in mitochondrial dysfunction — oxygen utilization, oxidative-inflammation balance, and the Nrf2 pathway. Major autohemotherapy (MAH) is well-tolerated; EBOO delivers a more comprehensive session for patients who fit.
Direct-delivery mitochondrial cofactors when oral absorption is impaired. Personalized to your labs — not template drips.
Not shotgun stacks. Specific cofactors chosen from your workup.
Fatigue rarely resolves while cortisol, thyroid, and sex hormones are off. Bioidentical HRT when indicated; thyroid replacement when the labs warrant it; adaptogens and lifestyle scaffolding for adrenal recovery.
Select FDA-approved and clinically established peptides used inside the fatigue framework. Full details on our Weight Loss & Peptides page.
Long COVID and post-viral fatigue have a distinct signature — mitochondrial dysfunction, endothelial inflammation, and immune dysregulation. Our combined ozone + IV nutrient + immune-modulation toolkit is a strong fit for this population.
Sleep evaluation & optimization
Poor sleep is the most consistently undertreated driver of fatigue, brain fog, hormone imbalance, weight gain, and immune dysfunction. Fixing sleep changes the trajectory of almost every other treatment.
A thorough sleep history, symptom screening, and review of wearable data (Oura, Whoop, Apple Watch, Fitbit). Circadian assessment. Screening for sleep apnea, insomnia, restless legs, and circadian rhythm disorders.
Home sleep testing (WatchPAT, Nox) or in-lab polysomnography referral when clinically indicated. We interpret results with you and coordinate treatment — you don’t have to figure out CPAP setup, oral appliance fitting, or ENT referrals on your own.
Careful review of what you're taking. Deprescribing benzodiazepines and Z-drugs (zolpidem, eszopiclone) when appropriate. Evaluating better options — trazodone, doxepin, ramelteon, dual orexin antagonists (suvorexant, lemborexant) — for the right patient.
CBT-I is the strongest evidence-based treatment for insomnia — we refer and coordinate. Targeted supplements dosed and timed correctly. Circadian light hygiene. Sleep-friendly HRT and progesterone strategies in perimenopause.
Sleep apnea treatment menu
CPAP works — when patients tolerate it. Roughly a third of people prescribed CPAP stop using it within the first year. That’s not failure — it means they need a different tool. We coordinate the full menu so you can find what works for you.
For moderate-to-severe obstructive sleep apnea, positive airway pressure remains the gold standard. We coordinate directly with Apria Healthcare for machine setup, mask fitting, and ongoing supply resupply.
For mild-to-moderate OSA, or for patients who can’t tolerate CPAP, custom-fitted oral appliances advance the lower jaw forward to keep the airway open during sleep. Made by a dentist trained in dental sleep medicine.
A structured tongue-and-airway exercise program taught by a myofunctional therapist. Strengthens the tongue and upper airway muscles to reduce collapse during sleep. Evidence supports it as adjunct therapy for mild OSA, snoring, and mouth breathing — and it can improve CPAP tolerance.
For positional OSA (worse when supine), simple positional devices can be highly effective. For patients whose sleep apnea is closely tied to weight, we coordinate weight-loss support alongside — GLP-1 therapy, nutrition, and metabolic care — recognizing that treating apnea and treating weight are linked.
Some patients need an anatomical evaluation — enlarged tonsils, deviated septum, nasal obstruction, or candidacy for Inspire hypoglossal nerve stimulation. We refer to ENT and sleep surgery specialists when the airway anatomy is the driver.
Many patients have both sleep apnea and insomnia (called COMISA — comorbid OSA and insomnia). Treating one without the other rarely works. CBT-I is the first-line, evidence-based treatment for chronic insomnia and often has to be done alongside apnea therapy.
The bottom line: if CPAP hasn’t worked for you, we don’t give up on treating your sleep apnea — we move to the next option. Untreated apnea drives fatigue, brain fog, cardiovascular risk, weight gain, hormone disruption, and cognitive decline. There’s almost always a workable option.

Common questions
Standard workup usually stops at a CBC, TSH, and iron. Those are worth doing — but if they're normal and you still feel awful, the workup shouldn't stop there. We add functional testing (methylation, DUTCH, MRT, gut, viral panels, mitochondrial markers) and treat what we find with tools most primary care offices don't offer.
Most patients see meaningful change within 60–90 days. Full mitochondrial recovery — especially post-viral or long COVID — is often a 6–12 month arc. We build the plan in phases so you're not paying for tests or therapies you don't need yet.
Some office visits and standard labs may be reimbursable out-of-network via a superbill — see Billing. Functional testing (DUTCH, MRT, gut, mitochondrial), IV therapy, ozone therapy, and peptides are typically cash-pay. HSA and FSA are often eligible.
No. We phase testing based on what your intake suggests is most likely — usually a foundational panel first, then targeted follow-up. You're never billed for tests we don't need.
Sometimes. If a medication is contributing to fatigue or mitochondrial stress (some statins, PPIs, benzodiazepines), we'll discuss whether adjusting or replacing it makes sense — always coordinated with your other prescribers.
Yes. Rosita is bilingual in English and Spanish, and the full program can be delivered in either language.
