Feeling tired even when taking good vitamins often points to a hidden genetic bottleneck. An SHMT1 gene test reveals if your folate is being wasted instead of repairing your tired body. Data shows that about 1 in 3 people have a genetic shift that blocks folate from reaching their DNA.
As a result, your recovery from stress or exercise can take much longer than it should. Stop the drain and start the repair.
The SHMT1 gene helps manage how folate is shared between two critical jobs. Think of SHMT1 as a traffic controller at a busy intersection. It helps decide whether folate is used to:
If SHMT1 is less efficient, folate may be pulled too heavily in one direction. This leaves the other side of your health without the support it needs.
Your DNA test reveals how well your SHMT1 gene manages the important balance between daily energy and cellular repair.
Balanced SHMT1 Activity:
Reduced SHMT1 Efficiency:
Most people hear about the MTHFR gene first. While MTHFR handles “activating” your folate, SHMT1 handles “distributing” it to the right places. You can have plenty of folate in your system, but you will still struggle if SHMT1 cannot direct it properly. This is why dnaPower includes SHMT1 in our comprehensive methylation panel.
Because SHMT1 controls where your folate goes, it can change how much energy you have and how quickly your body heals itself.

During high stress or illness, the body tries to prioritize DNA repair. If your SHMT1 gene is inefficient, it can be hard to meet these demands. Additionally, Canada’s use of synthetic folic acid in foods means many people get steady exposure to folate.
If your body cannot handle this folate correctly, it can contribute to symptoms rather than supporting your health. As we age, SHMT1 plays a quiet but critical role in keeping our cells healthy.
SHMT1 does not work alone. dnaPower evaluates it alongside other important genes, including:

Simple at-home cheek swab.

No doctor referral needed.

Safe and non-invasive.

Clear, easy-to-read results.
Understanding your SHMT1 status helps personalize:
If folate vitamins have not helped you feel better, the issue might be how that folate is being directed inside your body. Your genes hold the map to better energy and faster recovery. By understanding your SHMT1 status through our SHMT1 gene testing, you can stop guessing and start giving your cells the exact balance they need to thrive.
