Athletes typically have heard about these peptides through social media, podcasts or people in their circle who have used them, Frank said

Groups at increased risk of B12 deficiency include: Vegans and strict vegetarians , who avoid all animal products and are at significant risk without supplementation or fortified foods Older adults , in whom reduced stomach acid production impairs B12 absorption People with pernicious anaemia , an autoimmune condition that destroys intrinsic factor-producing cells Those who have undergone gastric surgery , including bariatric procedures, which can reduce intrinsic factor availability Individuals taking long-term metformin for type 2 diabetes, as this medication is associated with reduced B12 absorption the MHRA has issued specific safety advice on monitoring B12 levels in this group [6] [7] People with conditions affecting the small intestine , such as Crohn's disease or coeliac disease Symptoms of B12 deficiency can include fatigue, weakness, pins and needles, memory difficulties, and a sore or inflamed tongue (glossitis)

Peptides are small chains of amino acids that can influence various biological processes within the body
If you start to experience the side effects of decreased NAD levels (Loss of focus, inflammation, slow muscle development and recovery, lowered metabolism, weight gain, lack of energy, and autoimmune issues), you could be a good candidate for NAD injections, but we always recommend a consultation with our team
