What a vitamin and nutrient panel tests, and who is most likely to be low
Clinically reviewed by Pedro Alvarez, PA-C, Florida-licensed Physician Associate (PA9113765) · Last reviewed 2026-10-06
The short answer
A vitamin and nutrient panel is one blood draw that measures vitamin D, vitamin B12, folate, iron (with ferritin and iron-binding capacity), magnesium and zinc, plus a metabolic panel. It shows whether a low level could be contributing to how you feel. At Goza, in Florida, it costs $138.28 including a licensed provider’s review. No insurance is needed.
What is in the panel
| Test | What it looks at | Why it is useful |
|---|---|---|
| Vitamin D (25-hydroxyvitamin D) | Your vitamin D status | Low levels can weaken bones |
| Vitamin B12 | Your B12 level | Low B12 can leave you tired or weak |
| Folate | Your folate level | Low folate can cause mouth sores and changes in skin, hair or nails |
| Iron, TIBC and ferritin | Iron in the blood and iron in storage | Low stored iron leads to iron deficiency anemia, with tiredness and poor concentration |
| Magnesium | Magnesium in the blood | Long-term acid reflux medicine can lower it |
| Zinc | Zinc in the blood | Vegetarian and vegan diets can run low in zinc |
| Comprehensive metabolic panel | 14 substances, including calcium, kidney and liver markers | Gives context for the nutrient results |
Who is more likely to be low
The National Institutes of Health lists these groups.
- Vitamin B12: many older adults, people who eat little or no animal food, and people taking metformin.
- Folate: people with alcohol use disorder and people with conditions that lower nutrient absorption, such as celiac disease.
- Iron: women with heavy periods, pregnant women, frequent blood donors, and people with gastrointestinal disorders.
- Magnesium: people with gastrointestinal diseases, people with type 2 diabetes, people with long-term alcoholism, and older people.
- Zinc: people who follow vegetarian or vegan diets.
One result you can read yourself
Vitamin D, from the National Institutes of Health:
- Below 12 ng/mL is too low
- 20 ng/mL or above is adequate for most people
- Above 50 ng/mL is too high
More is not better. Levels that are too high can cause health problems, which is one reason to test before taking large doses.
What the guidelines actually say
For adults with no symptoms, the U.S. Preventive Services Task Force says the evidence is insufficient to recommend for or against routine vitamin D screening. There is no national recommendation to screen everyone for the other nutrients either.
So this panel is most useful when you have a reason to look: you are in one of the groups above, you have ongoing tiredness or weakness, or you already take supplements and want to know whether you need them.
Please do not start high-dose supplements based on a guess. If a level is low, your provider will tell you what to do about it and when to recheck.
How to prepare
- Go in the morning, fasting for 10 to 12 hours. Plain water is fine. Quest asks for a morning fasting sample for iron, because iron levels fall through the day.
- Mind your biotin. Quest advises drawing at least 8 hours after a regular dose of biotin and at least 72 hours after a high dose.
- Tell us about every supplement you take, including multivitamins and iron.
- Keep taking prescribed medicines unless your own prescriber has told you otherwise.
What happens after your draw
- Results usually arrive in 1 to 3 business days.
- A licensed Goza provider reviews them and sends you a written explanation of what is in range, what is not, and what to do next.
- If a result needs follow-up, you choose what happens next. You can book a video visit with a Goza provider to go over it and discuss any treatment we can offer by telehealth. Or we refer you to your primary care provider, or to other in-person care when that fits better. Either way, we say plainly which one applies.
Lab results are information, not a diagnosis on their own, and this panel is not for emergencies. If you have chest pain, trouble breathing, or any urgent symptom, call 911 or go to the nearest emergency room.
What it costs
- $138.28 all-in on Fullscript, our lab partner. That covers the lab tests, the draw at Quest, and the provider’s review of your results.
- Goza members: $89.28. The $49 clinician review fee is waived for members on every lab order.
- At-home blood draw is available for an extra $85.
- No insurance is needed, and nothing is billed to insurance.

Frequently asked questions
Should I stop my supplements before the test?
Tell us what you take and we will advise. Do not stop a prescribed supplement without asking your prescriber.
Will this panel explain my fatigue?
It can find or rule out several common contributors, including low iron and low B12. Fatigue has many causes, so a normal panel is useful information too.
If I am low, will Goza sell me supplements?
Your provider will explain your options. You are free to buy what you need anywhere.
How often should I retest?
Your provider will suggest a recheck interval if you start treatment for a low level. Otherwise there is no need to repeat it often.
