Vitamins and minerals are essential for bodily functions such as helping to fight infection, wound healing, making our bones strong and regulating hormones.

Magnesium promotes relaxation and sleep, boosting energy, while low levels may impair thinking and cause fatigue.

Vitamin D3 (cholecalciferol) is generally better than Vitamin D2 (ergocalciferol) because it is more effective at raising and maintaining blood levels of vitamin D, is produced naturally by the body from sunlight, and is often recommended by doctors for deficiency correction. While both forms increase vitamin D in the blood, D3 is more potent and longer-lasting, making it the preferred choice for most people, though D2 is suitable for vegans.

B12 deficiency can trigger specific food cravings, most notably for meat, fish, or eggs, as the body seeks animal-based sources to replenish the vitamin, especially in those on vegetarian/vegan diets or older adults. While cravings for sugary or salty foods can also signal general B-vitamin issues, the distinct urge for protein-rich animal products is a key indicator, but professional testing is crucial for confirmation.
While vitamin B12 is generally safe, taking excessively high doses, especially via injections, can cause side effects like headaches, nausea, diarrhea, dizziness, and skin rashes; rare serious issues include allergic reactions (anaphylaxis), increased heart rate, blood clots, and potential links to increased cancer risk or early death, requiring medical attention if severe symptoms appear.
Your muscles may lack strength. You also might feel tired or lightheaded. Your doctor can check how much B12 is in your body, but not all of it may be useable. So it's important to pay attention to any symptoms -- which can grow slowly or pop up more quickly -- and to alert your doctor.
