Supplementation with calcium, iron, and other vitamins and minerals can help optimize health for children and adolescents. However, there is no one-size-fits-all answer to this question. It depends on a child's age, weight, activity level, and other factors.

Here are some general guidelines to help you decide when to start supplementing your child with vitamins and minerals:

If your child is less than 6 years old and hasn't reached their final height or weight yet, it's not time to start supplementing them with vitamins and minerals yet. This is because their bodies are still growing and developing. You can also buy arma force junior online at https://botikaco.com.au/product/bioceuticals-armaforce-for-juniors/.

If your child is between the ages of 6 and 18 years old, it's generally safe to start supplementing them with calcium, iron, and other vitamins and minerals. However, some children may need more or less supplementation based on their individual needs. It's important to talk to your child's doctor about their specific needs.

If your child is over 18 years old, they don't need as many supplements as younger children because their bodies have already reached their final height or weight. However, it's still important for them to get regular servings of fruits, vegetables, and grains.
