Always good to have a reason I have also had this happen when my folate was low , it may be worth you getting it checked I had self inject my B12 every 4 weeks for the last 20+ (cannot really remember how long accurately), and 2 months ago got a similar 'electric shock tingling' all over my body - head, face, arms, hands, legs, feet etc within a couple of minutes of injecting, which lasted about 3 seconds or so
Research demonstrates the advantages of injectable B12 over oral supplements
NNMT inhibition with 5-Amino-1MQ reduced white adipose tissue mass by ~35% in diet-induced obese mouse models without suppressing food intake, suggesting energy expenditure modulation
People with Medical Conditions Affecting Absorption: Conditions like pernicious anaemia , Crohns disease , celiac disease , and gastrectomy reduce the bodys ability to absorb B12 from food, making injections a more reliable option
Pricing The program starts at $299 per month, before any applicable discounts
Q: When should someone use this injectable combination rather than oral supplements
