Common Deficiency Symptoms Common symptoms of Vitamin B12 deficiency include: Fatigue Weakness Pale skin Shortness Mouth Issues: Sore, red tongue, mouth ulcers, bleeding gums Gastrointestinal: Loss of appetite, weight loss, nausea, diarrhea, constipation Nerve issues like numbness/tingling Mood changes (depression, irritability) Memory problems Key Differences: NAD+ vs B12 NAD+ and B12 both boost energy, but NAD+ acts as a deep cellular, anti-aging repair agent, while B12 provides immediate metabolic energy and red blood cell support
Choosing the right form of B12 Some patients prefer injections because they are scheduled differently than daily supplements
As a supplement, Biotin is very safe
Its side effect profile is less well characterized due to limited human research
Its cellular-level mechanism appeals to those wanting to optimize metabolic function rather than override it
Amazing experience all around thank you
