Fatigue is common and can be caused by many things, including: Iron deficiency Low vitamin D Thyroid issues Poor sleep quality or sleep apnoea Stress and burnout Low mood/anxiety Dietary patterns and hydration Long-term conditions Thats why we always recommend basing B12 treatment on clinical context, and ideally blood test results, rather than guessing
If you require both medications, you need to take antibiotic medicine first and wait for 2 hours before taking multivitamins containing iron
Always start with a professional consultation : The only way to determine the right B12 type, dosage, and schedule for you is by working with a professional who can assess your health, lifestyle, and specific goals to create a safe and personalized plan
The increase in your B12 levels will also be fairly slow, meaning that it isnt a great option for those patients who need to see them boosted fairly quickly
For someone who is genuinely deficient, those risks are the more serious side of the equation
