Understanding Your TCN2 (Vitamin B12) Variants: A DNA Gene Report
Do you eat B12-rich foods but still wonder why your energy, focus, or lab numbers don’t feel “optimal”? Have you ever been told your homocysteine is high—or that your B12 looks normal, yet symptoms persist? Your TCN2 (Vitamin B12) gene helps deliver vitamin B12 into your cells, and understanding your TCN2 genetic variants can reveal whether you may need a more personalized approach to getting enough active B12 where it matters most.
Key Report Highlights
This DNA report analyzes genetic variants in the TCN2 (Vitamin B12) gene and translates your results into 3 personalized recommendations tailored to your genotype. TCN2 encodes transcobalamin, the carrier protein that binds vitamin B12 and transports it into cells, where B12 supports essential methylation reactions—like converting homocysteine to methionine. A compelling takeaway: certain TCN2 variants are linked to lower levels of active B12 (holotranscobalamin) and, in some populations, higher homocysteine—two markers closely tied to cardiovascular and cognitive health foundations.
Personalized, Actionable Recommendations
Your recommendations are personalized to your TCN2 (Vitamin B12) genotype, helping you focus on the dietary and supplement strategies most likely to support healthy B12 status and methylation. Depending on your results, you may see guidance such as prioritizing B12-rich foods (e.g., fish, eggs, dairy, or fortified options) and pairing them with supportive nutrients, or targeted supplement suggestions (for example, choosing an appropriate form and dose of vitamin B12 and timing it consistently). The goal is practical, DNA-informed steps that align with how your body may transport and utilize B12.
User-Friendly Format and Trust
With actionable and easy-to-understand recommendations, the report is designed for seamless integration into your daily life. Its user-friendly format ensures accessibility, making complex genetic data understandable and practical for users at all levels of familiarity with genetic information.
The report is rooted in accuracy and reliability, backed by comprehensive scientific research from reputable sources. It has garnered the trust of over 150,000 users and 1,000+ healthcare professionals. Furthermore, the report complies with HIPAA and GDPR, ensuring your privacy and security are prioritized.

B12 transport, decoded fast.

The TCN2 (Vitamin B12) report connected a lot of dots for me. I’ve had on and off tingling in my hands and a weird “foggy” feeling, but my basic labs were always borderline and I kept shrugging it off. Seeing how TCN2 can affect B12 transport made me take it seriously. I started a consistent vitamin B12 supplement, prioritized dietary vitamin B12 at breakfast, and followed the “limit alcohol to up to 1 drink a day” suggestion. Within a few weeks my energy felt steadier, and I stopped getting that afternoon crash.

I’ve purchased several different health analyses from this platform and the tcn2 vitamin b12 one is definitely one of my favorites. It gave clear steps and actually helped me see what changes made sense for me personally. Super useful compared to some others I’ve tried before.
