Unfortunately, signs and symptoms of low B vitamin levels can be vague and subtle – fatigue, mood swings, sleep disturbance, and brain fog, etc. Testing of B vitamin levels is also unreliable and doesn’t always align with clinical outcome. This means that we don’t know for certain whether you will benefit or not. That being said, an overwhelming majority of Voda Health clients notice a benefit after the very first shot! Because vitamin B injections are extremely safe, they are not many instances when one does not qualify. Take the quiz to see if you would be a good candidate to give it a shot.
