At Home Nutrient & Energy Markers Test

Losing Weight Quickly? Check What It's Costing You

A 4-marker blood test for B12, Vitamin D, ferritin, and kidney function. Results explained in plain English in 5–7 days.

FREE shipping both ways.

Equivalent testing typically costs $400+ through a clinic or hospital-billed visit.

Rapid weight loss, whether from diet changes, intense training, or GLP-1 medications, can quietly deplete the nutrients your energy depends on. Eating less means absorbing less: B12, vitamin D, and iron stores often drop first, and they're the difference between losing weight and losing strength. This 4-marker at-home test (B12, vitamin D, ferritin, creatinine) shows you your levels in 5-7 days, no lab visit, so you can support what your body needs while the scale moves. Retest along the way and watch your levels, not just your weight.

Who is it for?

This at home blood test is perfect for people who feel tired all the time, have low energy, or want to make sure they're getting enough essential nutrients. Fatigue, brain fog, hair changes and mood swings are often a deficiency, not a personality flaw or a phase.

The At Home Nutrient & Energy Markers Test is ideal for:

Anyone experiencing low energy, fatigue, or brain fog who wants to check for vitamin deficiencies
People following vegetarian or vegan diets who need regular vitamin B12 testing
Athletes and active individuals who want to optimize their performance with at home lab tests
Anyone with hair loss, pale skin, or other signs of possible iron deficiency
People taking supplements who want proof their supplementation is working
Anyone concerned about vitamin D levels, especially during winter months

What's Included:

This at home blood test measures 4 critical nutrient and energy markers your doctor probably skipped:

Essential for energy production, brain function, and making red blood cells. Low levels cause fatigue, brain fog, and weakness. Especially important for vegetarians and vegans.

Critical for immune function, bone health, mood, and overall vitality. Most Americans are deficient, especially in winter. This at home vitamin D test helps you track your levels.

Shows how much iron your body has stored. Low ferritin causes fatigue, hair loss, and poor exercise performance. This is often the first marker to drop in iron deficiency, even before anemia develops.

Measures kidney health and function. Also provides context for overall metabolic health and helps interpret other markers.

Standard annual bloodwork misses them. We don't.

Why this test matters:

Vitamin and nutrient deficiencies are incredibly common, but most doctors don't check for them unless you have severe symptoms. By the time symptoms appear, you've often been deficient for months or years.

This at home nutrient test catches deficiencies early:

Low Vitamin B12 causes constant fatigue, memory problems, depression, and nerve damage over time. Vegetarians, vegans, and people over 50 are at highest risk. Regular at home vitamin testing helps you stay ahead of deficiency.

Low Vitamin D weakens your immune system, affects your mood, and increases risk of bone problems. Studies show that optimal vitamin D levels support better health outcomes. An at home vitamin D test is the easiest way to track your levels.

Low Ferritin drains your energy even before you develop anemia. Women, athletes, and people with digestive issues are especially at risk. This at home iron test (ferritin) is more sensitive than standard anemia tests.

With this at home lab test, you get real data about your nutrient status. No more guessing if your supplements are working or if your diet is providing enough nutrients.

How often you should get it done:

If you're experiencing low energy or fatigue, take this at home blood test to establish a baseline. If you have deficiencies, retest after 2-3 months of supplementation to see if your levels improved.

Once your levels are optimal, test once or twice a year to maintain healthy ranges with convenient home blood testing.

If you follow a restrictive diet or have absorption issues, more frequent at home lab work (every 3-4 months) helps ensure you stay in healthy ranges.
