What's this test for?

This test is ideal if you're experiencing persistent fatigue, low energy, brain fog, weak immunity, or unexplained health issues despite eating well. It helps identify hidden vitamin deficiencies that may be affecting your energy levels, mood, immune function, and overall wellness. Many people use this test when they suspect their diet isn't providing adequate nutrients or when they want to optimize their health and performance.

How should I prepare for this test?

Fasting: 8 hours

You should fast for 8 hours before your blood draw, consuming only water during this time. Avoid eating liver and refrain from taking multivitamins or vitamin K supplements for at least 24 hours before collection. Also avoid eating fruits and taking vitamin C supplements for 24 hours prior to testing to ensure accurate results.

What's included in this test?

Vitamin C Vitamin B2 (Riboflavin) Vitamin K Vitamin B1 (Thiamine), Blood, LC/MS/Ms Vitamin B5 (Pantothenic Acid) Vitamin A (Retinol) Vitamin B6 Vitamin B12

This comprehensive panel evaluates all essential vitamins your body needs for optimal function. It measures the complete B vitamin complex (B1, B2, B3, B5, B6, and B12) which are crucial for energy production and brain function, plus vitamins A, D, E, K, and C that support immunity, bone health, antioxidant protection, blood clotting, and cellular repair. Together, these measurements provide a complete picture of your nutritional status and identify any deficiencies that may be holding back your health and vitality.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your vitamin levels mean for your energy, immunity, and overall health. These notes include personalized recommendations like dietary changes, specific supplement suggestions, and which vitamins to prioritize based on your results. You'll also get the standard lab report and can track your vitamin levels over time using our trends feature to see how your nutrition improvements are working.
When will I get my results?
You can expect to receive your results within approximately 7 business days after your blood sample is collected. If any confirmation testing is needed for certain biomarkers, the turnaround time may be extended slightly, but you'll be notified if this occurs.
Who should consider getting this test?
This test is ideal for anyone experiencing chronic fatigue or low energy, people following restrictive diets (vegetarian, vegan, keto), athletes looking to optimize performance, and individuals with digestive issues that may affect nutrient absorption. It's also valuable for those with unexplained symptoms like muscle weakness, poor wound healing, frequent infections, or anyone who wants to ensure their supplement routine is actually working.
What symptoms indicate I may need this test?
Common signs of vitamin deficiencies include persistent tiredness despite adequate sleep, difficulty concentrating or brain fog, frequent colds or infections, slow wound healing, muscle weakness or cramps, tingling in hands or feet, mood changes or depression, and brittle hair or nails. If you're experiencing several of these symptoms or feel generally unwell without a clear cause, vitamin deficiencies could be the underlying issue.
How can I naturally improve my vitamin levels?
Focus on eating a varied, colorful diet rich in whole foods including leafy greens, citrus fruits, nuts, seeds, eggs, fatty fish, and lean meats. Get 15-20 minutes of sunlight daily for vitamin D production, and consider fermented foods for better nutrient absorption. Reduce alcohol consumption and manage stress, as both can deplete B vitamins, and ensure you're getting adequate healthy fats to absorb fat-soluble vitamins A, D, E, and K.
What are B vitamins and why do they matter?
B vitamins are a group of eight essential nutrients (B1, B2, B3, B5, B6, B12, biotin, and folate) that work together to convert food into energy and support brain function. They're crucial for energy production, red blood cell formation, nervous system health, and DNA synthesis. Since B vitamins are water-soluble and not stored in the body, you need a consistent daily intake through diet or supplements to maintain optimal levels.
What does low vitamin D mean?
Low vitamin D levels indicate your body isn't getting enough of this crucial nutrient from sunlight exposure, diet, or supplements. This deficiency can lead to fatigue, weakened immunity, bone pain, muscle weakness, and mood issues like depression. Low vitamin D is extremely common, especially in people who spend most time indoors, live in northern climates, have darker skin, or are overweight.
How often should I retest my vitamin levels?
If you're starting supplementation or making dietary changes to address deficiencies, retest in 3-6 months to ensure your levels are improving and your approach is working. Once your vitamin levels are optimal, annual testing is recommended to maintain your nutritional status and catch any emerging deficiencies early. If you have ongoing health conditions, digestive issues, or follow a restrictive diet, more frequent testing every 6 months may be beneficial.

What this means

Your vitamin D level is below the optimal range, which is very common but can impact your energy, immunity, mood, and bone health. While not severely deficient, this level may contribute to fatigue, frequent infections, or feeling down, especially during winter months.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
