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.

$156.00

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.

We work with CLIA-certified laboratories. Each lab meets the state and federal highest qualities for testing.

No doctor's referral needed, convenient at-home testing.

All tests are reviewed by an independent board-certified physician - ensuring reliable and accurate results.

Sage and our tests are HIPAA-Compliant. Your data is 100% secure and private.

I’ve been using the Sage Hormone Optimization Kit and really love how simple and easy the whole process is. It helped me feel more in tune with my body without being overwhelming, which is huge with my busy schedule. Everything felt very smooth and well put together—definitely something I’d recommend.

The process was so much easier than I thought it would be! The kit arrived fast and the directions on my phone were easy to follow along with. I’m glad they told me the blood draw may take a minute to activate because I felt NOTHING. I was convinced I did something wrong! Even if you’re afraid of needles normally—this is the test for you!
The results made it easy for me to take the information to various providers FAST and I was able to import other tests I’ve had done over the past 2 years to see an overall health profile on the app. I’m a huge believer in taking your health into your own hands and making sure you aren’t a passive observer and this is one way to help make progress! Thank you Sage Healthspan!!

I’ve absolutely loved my experience with the Sage Female Hormone Optimization Kit. The entire process was simple, informative, and empowering from start to finish. I appreciated being able to gain real insight into my hormone health from home instead of guessing what my body needed. The recommendations felt personalized, the supplements were easy to incorporate into my routine, and within a few weeks I noticed improvements in my energy, mood, recovery, and overall well-being. It truly made me feel more in tune with my body and proactive about my health

Love how easy and painless this is!!! It's great and so much better than going to the doctor!

Super easy and painless. Zinc got my T up, creatine helped in the gym and with the mag, I'm sleeping like a baby.

Amazing! So easy, no pain and fast!!! I’m am a hard sticky and honestly just too busy to find time to go to the doctor and then to the lab. This was perfect! Highly recommended!!

This is a now the new norm for me.
To be able to test my blood, painlessly, and in the comfort of my own home is literally a game changer for me!
I HATED going to the doctors and having them jab me in the arm.
The Sage Optimization kit was literally painless and took me all of 5 minutes!
And now I have the products my body actually needs. Couldnt be happier.

Really impressed with the home testing kit, incredibly easy, pain free, fast results and great price!

I found Sage Healthspan through social media, and I'm so glad I did!! I loved the depth of th erestults and ease of everything. I finally felt like someone was trying to help me live a better life vs just treating symptoms.

The kit was so simple to use and such a reassuring way to check my hormones.

Easy at home test. Highly recommend it.

Gym workouts have been feeling fantastic and even more pleasantly, my mind feels sharper!

As a perimenopausal woman I was concerned about recent weight gain and wanted to check both my hormones and my thyroid. This product was great! It came to my house within 2 days, was painless and I received my results in two days. I learned that my thyroid was low and was able to speak to my doctor about it and work together to improve it. Thanks Sage!

Thank you...good stuff!!!

So Glad I Found This!!!

As a 50-year-old guy, I'm doing everything I can to keep my testosterone where it needs to be — and this is by far the easiest way I've found to actually track it. It's quick, totally painless, and doesn't require me to wait for a doctor's visit. Did I mention painless? And I don't just mean the test itself — I mean no more dealing with the pain of scheduling appointments and the variability you get with Quest or LabCorp. The turnaround was impressively fast too.

BTW — I'm also on SageMD Defense, Calm, and Power, and I'm feeling my best. This test helps me see whether what I'm doing is actually working. Highly recommend for any guy who wants to stay on top of his health.

I honestly wasn’t sure how this was going to go but I’m actually impressed. I placed my order, received a shipping confirmation the next day, and a day later the test was delivered. So fast. I did the test on a Monday and sent it back the same day. The lab got it Tuesday and I woke up on Thursday to my results. I cannot believe has fast the turnaround was. I’ll definitely be ordering another test in May to see if my numbers improve.

I cannot believe how quickly the results were ready. I was not sure about how easy it would be so I sat on the product for like a week before I decided to finally do it. It was easy and the instruction were super simple. Highly recommend this!

Best magnesium product! I am sleeping GREAT!

I purchased this after seeming an ad and am very happy. I feel so much better after taking this every morning. I definitely feel stronger and am recovering faster. Would definitely recommend!

I wanted something I knew wasn’t just full of chemicals and fillers and this is it. You can’t always trust what’s in supermarkets. I’ve been happy with everything I’ve bought off this site. I’ve done this plus the krill and the probiotics. All have been great.

I don’t even suck on these. I just chew them (they’re tasty) and it works just as well. No weird aftertaste. Managing to get through this Chicago winter without getting sick. I’m sold.

Great product! I truly believe zinc is the key to health year round!

This came highly recommended to me by a health care professional and I'm excited to give it a shot! Easy to incorporate into my night time routine!

My kids don’t mind taking these. The flavor is good without being overly sweet. Keeping us as healthy as possible.

Works like a charm. No more melatonin for me. I love that I ca he to sleep more naturally this way.

I picked this up because I was having trouble sleeping. My life is pretty stressful and I really need quality rest to function. After taking it for a while I started noticing I actually feel more rested in the morning. Not groggy, just like I actually slept. I'm sticking with it.

I swear by these to get me through the winter. I work in healthcare AND have kids of my own, so germs are always around. Since taking this, I’ve gone from being sick all winter long to maybe 1 cold a season. Lifesaver!

Goes great in my coffee every morning. Super easy to dissolve and leave no strange flavor.

Was surprised that in just 3 months my testosterone increased 24% and so far have made it through the fall with kids in school without getting sick once.

Works great. Sleep improved dramatically.

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.

Doctor and patient in a consultation setting

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.
