Although some of the supplement doses are very high (for instance, 500 or 1,000 micrograms when a healthy adult only needs 2.4 micrograms per day), your body only absorbs what it needs and pees the rest out

Practical management strategies include: Cycle tracking: Use a menstrual diary or smartphone application to document cycle length, flow characteristics, and associated symptoms Nutritional adequacy: Ensure sufficient caloric intake to support metabolic health despite weight loss goals

Clinicians may use a B1-B6-B12 injection to address symptomatic vitamin B deficiency and to support nerve function in conditions such as peripheral neuropathy, neuritis, and neuralgia

Summary: B12 injections are evidence-based treatments for confirmed vitamin B12 deficiency, whilst lipotropic injections are unlicensed combinations marketed for weight loss without robust clinical evidence or NHS endorsement
