Zinzino Vitamin D Test is an advanced, self-administered dried blood spot test that allows you to accurately measure your personal vitamin D levels from the comfort of your own home. Vitamin D is an essential hormone-like nutrient that plays a critical role in bone strength, immune defence, mood regulation, cardiovascular health, and cellular repair. Yet global studies show that a large proportion of the population is deficient without even realising it, due to limited sun exposure, seasonal changes, skin type, lifestyle factors, and inadequate dietary intake.

Unlike standard blood tests that may only give a basic reading, the Zinzino Vitamin D Test is analysed at the independent Vitas Analytical Services Laboratory in Norway, one of the world’s most advanced laboratories specialising in fatty acid and fat-soluble vitamin analysis. Using just a few drops of blood collected on a filter card, the test provides an accurate assessment of your vitamin D status with results expressed in nmol/L or ng/mL, depending on your region.

This test is particularly valuable because vitamin D deficiency often goes unnoticed until it leads to long-term consequences such as weakened bones, higher susceptibility to infections, impaired muscle strength, or low mood. By understanding your personal level, you can take targeted action through supplementation, diet, and lifestyle to achieve and maintain an optimal range.

Vitamin D is closely linked to immune resilience, inflammatory control, and the skin repair processes. Knowing your status provides a measurable baseline, enabling you to track improvements over time through repeat testing.

The Zinzino Vitamin D Test is an empowering tool that helps you move away from guesswork and towards evidence-based wellness. By combining the test with The Beauty Bistro’s professional guidance, you can be confident that your supplementation is both necessary and effective, ensuring long-term protection for your health, energy, and skin vitality.

Taking the test

1. Zinzino Test is an approved in vitro diagnostics product for personal blood sample collection at home.
– First, wash your hands with soap and rinse well with warm water, and dry them.

2. Take out the Zinzino test sample card from the paper envelope. Save the envelope for later use.
Tear off the SAVE part on the sample card and take a picture of the test ID. You can only see your test result with your anonymous test ID. Place the card with the two circles facing up on the table.

3. Stimulate blood flow by making big circles with your arm or shaking your hand downwards for 20 seconds.

4. Take out the single-use lancet. Remove the transparent safety cap, and the lancet is ready to use. Use the alcohol wipe to clean the tip of your finger (the middle finger is recommended). Place the lancet against the lower part of the skin on the fingertip, facing the collection paper on the table. Push the top of the lancet towards the finger until you hear a click. The lancet will automatically make a small prick in the finger.

5. Do not touch the filter test paper with your fingers.

6. Fill one circle at a time with blood. Squeeze your finger gently and wait for a drop of blood to fall inside the circle by itself. If one drop of blood does not cover the circle, allow one more drop from your finger to drip immediately. Leave the sample card in a horizontal position at room temperature for at least 10 minutes for the samples to dry well.

7. Insert the Zinzino Vitamin D sample card back into the paper envelope. Then place the paper envelope into the metal bag and close it.

IMPORTANT: Do not remove the desiccant packet inside the metal bag.

8. Place the closed metal bag into the big envelope with the laboratory address on it.

NOTE! You must put the correct amount of postage stamps on the envelope before you put it in the mail box.
