Science Vitamin B12 Bites: Our Clinical Trial Results
Nov 02, 2022 3 min. read

There's no shortage of new supplements on the market: gummies, bars, beverages and other types of functional foods. This area continues to grow as people look for new ways to get their supplements.

But are they all effective? The FDA doesn’t approve dietary supplements before they enter the market so it’s up to the company selling the product to prove the claims they’re making are real. If you’re looking for a new supplement, it’s smart to check it’s scientifically sound before hitting "purchase."

The only way to be totally sure is third party clinical testing. We’re results driven and stand behind all the products we make. We created Sourse to help you – whether you’re B12 deficient or looking for healthy skin – and want you to know you’re getting the nutrients you’re paying for.

We're thrilled to share we recently completed a clinical trial for Vitamin B12 Bites! We understand how important B12 supplementation is and decided to get these clinical results for you. We want you to be confident chocolate is an effective delivery format for vitamins and know you don’t have to compromise when it comes to your health.

The importance of B12

First, why B12? Vitamin B12 is a key nutrient for nervous system health. It metabolizes energy, creates red blood cells, and helps make DNA. Low levels or deficiency can cause depression, anxiety, brain fog, fatigue, and more. 

People on a vegan or vegetarian diet are likely not getting enough B12 because it’s traditionally found in animal proteins. We created Vitamin B12 Bites with B12 as methylcobalamin, the most bioavailable form of vitamin B12. It’s also able to be absorbed through the mouth instead of the stomach, which makes chocolate a particularly effective format.

About our study

This study is an IRB (Institutional Review Board) approved clinical research trial investigating biological and subjective health outcomes of Vitamin B12 Bites over an 8 week period of supplementing daily. We partnered with Citruslabs, a research organization conducting third party clinical testing for unbiased confidence and trust.

This trial was a single group study of healthy men and women aged 24-65 who were on a consistent vegan or vegetarian diet. Participants completed surveys at baseline, week 4, and week 8. Participants also submitted blood samples at baseline and the end of week 8.

The results

Vitamin B12 Bites were shown to cause significant improvements in brain fog, concentration, focus, and energy levels. Participants also had more mental clarity, better perception of their mental health, and were better able to deal with stressors. 

Participants also scored significantly better on memory and recall tasks at the end of the trial compared to the study baseline. Importantly, participants had significantly higher vitamin B12 in their blood at the end of the study compared to baseline.
