The exact shade depends on their B12 concentration
For these individuals, vitamin B12 injections are often the most effective way to restore healthy B12 levels because they bypass the digestive system entirely, delivering the vitamin directly into the bloodstream for maximum absorption (around 95% compared to 25-50% for oral supplements)
Rather than acting like a stimulant or quick caffeine boost, NAD supports the foundational processes that help your body function more efficiently from within
Over time, it can cause irreversible nerve damage, cognitive decline, and mental health disorders such as depression
This method ensures rapid absorption, allowing the body to utilize the vitamin more efficiently than oral supplements
