    Is Your Body Low in B12?

    (6 signs that you might be)

    The “Always Tired” Feeling


    If you’re relying on daily naps but still lack energy, your body is likely craving more B12.


    The Tingling Sensation


    Tingling in your fingers, toes, or face—known as neuropathy—often signals low B12, caused by improper nerve function.


    The Swollen Tongue


    If your tongue feels too big for your mouth—smooth, swollen, and enlarged—you’re likely low on B12.


    The Brain Fog


    Struggling with focus, forgetfulness, or cloudy thinking? These are key signs of low B12.


    The Unsteady Walk


    Feeling off-balance or clumsy? If you’re not walking right, it’s a major red flag for low B12.


    The Constant Ringing


    A persistent ringing in your ears can be linked to low B12, often mistaken for hearing loss. Boosting B12 might be the quick fix you need.*

    Most B12 Supplements Don't Work.

    The Problem with Most B12 Supplements


    Wrong Form: Many supplements use cyanocobalamin, a synthetic form of B12 that your body can’t absorb efficiently.


    Poor Delivery: Swallowing B12 doesn’t work well. Your body needs something called intrinsic factor to absorb it, and most pills pass through your system without giving you the B12 boost you need.


    Low Dosage: A weak dose won’t bring your levels to where they need to be.

    The Superior Solution.

    Our sublingual B12 supplement is designed to overcome these challenges:


    Methylcobalamin: The natural, most absorbable form of B12.


    Sublingual Delivery: Melts under your tongue, bypassing the digestive system for direct absorption into the bloodstream.


    Optimal Dosage: 4000 MCGs to quickly elevate and maintain your B12 levels.

    QUESTIONS? WE'VE GOT YOU COVERED

    We use Methylcobalamin, a bioavailable form of B12 for better absorption.  Others use Cyanocobalamin, a synthetic form that's less effective.


    We use a sublingual tablets that dissolve for maximum nutrient uptake.  Others use capsules or tablets that don't dissolve well, leading to poor absorption.


    Our B12 provides  a robust 4000mcg dosage per tablet for optimal results.  Others typically offer weaker dosages of 1000mcg or less.

    B12 is often called the "energy vitamin." It's needed to make red blood cells, nerves, and DNA. If you're deficient in B12, you might experience a range of symptoms such as fatigue, heart palpitations, depression, anxiety, confusion, and even nerve pain.

    Our B12 is sublingual, meaning it dissolves under the tongue.  This is important because B12 absorption in the stomach requires a substance called intrinsic factor. 


    If you have any digestive issues, you might have a problem absorbing B12.  By taking a sublingual B12, you bypass the need for intrinsic factor, allowing for better absorption.


    Bottom line: You should avoid taking B12 in a capsule or tablet if you don't want expensive urine.

    Most B12 supplements on the market are in the form of cyanocobalamin, which is a synthetic and less effective form.  You should know that cyanocobalamin isn’t found anywhere in nature.


    Our B12 supplement is in the form of methylcobalamin, which is a natural and more effective form.
