A deeper look at the nutrients your body needs to make energy, think clearly, and feel like yourself.
Tired all the time. Brain fog by mid-afternoon. Workouts that feel harder than they should. Hair thinning or shedding more than usual. Sleep that doesn't restore you. When fatigue becomes your baseline, it's easy to chalk it up to stress, age, or a busy life. But often, the body is signaling a nutrient gap that standard bloodwork misses.
This panel looks at the vitamins, minerals, and iron markers most closely tied to energy production, mental clarity, and physical stamina. It's designed to help you understand whether what you're feeling has a measurable, correctable cause.
Anyone, men or women, who is experiencing persistent fatigue, low energy, brain fog, hair thinning, poor exercise tolerance, or simply wants to know whether key nutrient levels are supporting them the way they should be.
It's also a smart baseline for anyone eating a restrictive diet (plant-based, low-carb, intermittent fasting) or taking medications known to deplete nutrients over time.
Iron status and blood counts are most meaningful when read together. A CBC can show anemia, but it takes a full iron panel to explain why. A ferritin value alone can be misleading without seeing iron and TIBC alongside it. And none of these markers, on their own, account for the nutrient deficiencies (B12, folate, magnesium, vitamin D) that can cause fatigue even when your blood counts look normal.
If you've already run a wellness baseline or a standalone iron panel and still don't have answers, this panel fills in the gaps. If you're starting fresh and fatigue is your main concern, this is the place to start.
Vitamin D (25-OH). Widely under-measured and often low. Impacts energy, mood, immune function, and bone health.
Vitamin B12 and folate panel. Both are essential for energy production and red blood cell formation. Low B12 in particular is linked to fatigue, brain fog, tingling, and mood changes, and is often missed in routine bloodwork.
Magnesium, RBC. The more accurate version of magnesium testing. Standard serum magnesium can look normal even when your body's actual stores are depleted. Magnesium supports sleep, muscle function, blood sugar regulation, and over 300 enzyme processes in the body.
Iron panel (iron, TIBC, ferritin). A full look at iron status, not just hemoglobin. Ferritin reflects your iron storage, iron and TIBC tell you whether your body is absorbing and transporting iron well. Low iron is one of the most common and most missed causes of fatigue, especially in women who menstruate.
Complete Blood Count (CBC). Looks at red blood cells, white blood cells, and platelets. Relevant here because true anemia, infection, and other blood-level issues also show up as fatigue.
Numbers on a page are data, not a diagnosis or a treatment plan. Nutrient deficiencies often have multiple causes (diet, absorption, medications, underlying conditions) that a single lab result can't explain on its own.
If you'd like help understanding what your results mean, you have options.
For residents of Virginia, Maryland, DC, and Delaware, you can book an interpretation visit with Discreet Health for a clear, educational walk-through of your numbers.
If you live elsewhere, we recommend following up with a licensed clinician in your state.
If you're looking for a treatment plan or ongoing care beyond interpretation, that lives in our clinical programs (available only to residents of VA, MD, DC, and DE).
Fasting and Timing
This panel is best run fasting, with a morning draw when possible. Plan to fast for 8 to 12 hours before your appointment. Water is fine. The iron markers in particular are most accurate when drawn in the morning after an overnight fast.
A dried urine test that measures sex hormones, adrenal hormones, and the metabolites your body produces as it processes them. Often chosen by women already on hormone therapy who want additional detail. We're upfront about where this test is useful and where blood work gives us more reliable answers.
A look at how your cortisol rises, falls, and settles across the day. Useful for understanding stress patterns, sleep issues, and HPA axis dysregulation when blood cortisol alone doesn't tell the full story.
A comprehensive stool test that identifies gut bacteria, yeast, parasites, and markers of digestion, inflammation, and intestinal barrier function. Often chosen by women investigating digestive symptoms or the gut-hormone connection.
A urine-based test that measures mycotoxins (toxic byproducts of mold) in your body. Often chosen by women with a history of water-damaged buildings or unexplained symptoms that haven't responded to other interventions.
An at-home test that uses DNA analysis to identify the bacteria, yeast, and organisms living in your vaginal microbiome. Often chosen by women with recurrent symptoms or those investigating the connection between hormones, the gut, and vaginal health.
