Talk to your doctor
Regardless of your age or gender, before taking any dietary supplements or vitamin pills, you should talk to your doctor. He or she will perform some tests to determine what you are lacking, which supplements to take, and how much.
In fact, usually, nutritionists will prioritize you to increase your consumption of natural foods, a scientific lifestyle and rest, and then the dosage of supplements needed to improve your health. It will be very dangerous if you arbitrarily use supplements without a doctor's prescription.
Notes for each subject
Children: The American Academy of Pediatrics recommends that parents begin supplementing vitamin D for infants as early as a few days old. If the daily intake from breast milk or formula is less than the recommended amount, then we will need to supplement the vitamin from an external source for the child.
For babies around 4 months old, additional iron sources are needed until they start eating solid foods. Mothers are encouraged to feed their babies foods rich in iron, such as red meat, yogurt, iron-rich vegetables, etc.
Pregnant women: During pregnancy, women are also at risk of deficiencies in nutrients such as iron, calcium, choline and iodine, etc. Depending on the case, pregnant women may need to supplement these types.
Elderly: For the elderly, vitamin B12 sources are found in beef, chicken, fish, shellfish, milk and other dairy products. Vitamin B12 is also found in breakfast cereals. If the body is still deficient, we should consider taking vitamin pills and other supplements.
