Please note: Supplements are generally not FDA tested or approved. Some supplements can interfere with medications and/or cause side effects. Do not delay seeking medical attention for medical concerns by taking supplements without medical advice. Have your child get a medical checkup if you suspect an immune problem and be sure to clear any supplement use with the child’s health care provider.

When your little one has a healthy immune system, their body can fight threats and recover faster. It decreases the severity and duration of illnesses when they happen and lowers their chances of developing allergies or autoimmune issues in the future.
However, not all children have strong immunity. Some may have a weak one and difficulties strengthening it because of various causes, such as malnutrition, stress, inactivity, and poor living conditions.
Fortunately, there are several ways to boost a child’s weak immune system. One supplement is whey powder, for example in GcMAF lollies and improving their diet to encouraging them to practice good hygiene and be more physically active, you can help strengthen their immunity and stay healthy.
Does Your Child Have a Weak Immune System?
Children with a weak immune system may show these signs and symptoms:
1. Frequent colds
A healthy immune system protects the body from common viral illnesses, including colds, coughs, and flu. This is why most children typically get colds only three to four times a year.
If your little one frequently gets a cold on nearly a monthly basis, they may have a weak immune system that can’t fight even common viruses.
2. Digestive problems
Frequent stomach aches, constipation, diarrhoea, and other digestive issues are often more than just a sign of picky eating or stress in kids. The gut plays a big role in immune function since a portion of the immune system is in the digestive tract.
When the gut isn’t working well, it affects the balance of good bacteria that help protect the body from illness. This can leave a child more vulnerable to infections or slow to recover from them.
Frequent digestive problems might mean their immune system isn’t working properly and needs additional support.
3. Fatigue
Children often have plenty of energy, so it can be difficult to ask them to stay still, even for a few minutes.
If your child seems less energetic and physically active than their classmates, friends, and other kids, they may be dealing with poor immunity. Their weak immune system may not give them the energy they need to engage in various activities.
As such, be wary if your little one tends to lie down, sleep, or simply sit still, even if they have plenty of fun things to do.
4. Recurring infections and injuries that take too long to heal.
The immune system protects the body from germs and bacteria and helps repair body tissues. Low immunity slows down healing, which causes cuts to stay red or swollen longer than expected.
Colds, asthma, pneumonia, and other infections may also become harder to treat as they keep coming back.
Slow healing is the body’s way of signalling that its defence and repair systems are not working efficiently.
Getting stressed easily, poor appetite, anaemia, and recurrent fevers are also common signs of poor immunity.
What Can You Do to Strengthen Your Child’s Weak Immune System?
If you notice these signs and symptoms in your child and a doctor confirms that they have low immunity, your next step is to strengthen it. Below are some tips to help you do this:
1. Consider give your child a daily GcMAF supplement.
GcMAF supplements, such as GcMAF lollies, powder, and capsules from MAF Supplies, contain derived from bovine colostrum.
2. Make changes to your child’s diet.
Certain nutrients can boost your little one’s weak immune system. Examples of these are vitamins B-complex, A, C, and E, zinc, and magnesium.
Giving your child a balanced diet ensures they get these nutrients. As such, make sure their daily meals and snacks consist of different vegetables, fruits, lean proteins, whole grains, and dairy products, and encourage them to drink plenty of water.
3. Teach your child good hygiene habits.
Instil the importance of good hygiene habits, like taking a bath regularly and washing their hands after using the bathroom and before eating. This helps cut down on the spread of viruses and bacteria. Also, teach them how to cover coughs and sneezes.
Make it part of your child’s daily routine so it becomes second nature to them and not a chore.
4. Encourage your child to be more physically active.
When kids are active, their blood circulation improves, which helps immune cells move freely throughout the body.
As such, encourage your child to engage in regular workouts. These can include biking, swimming, hiking, playing tag, or even walking around the neighbourhood for 30 minutes a day.
5. Ensure your child gets enough good-quality sleep.
During deep sleep, the body produces important proteins like cytokines, which target infection and inflammation. Because of this, make sure your child gets sufficient sleep every night.
Create a bedtime routine to help your little one wind down at night. This includes turning off screens, dimming the lights, and keeping the schedule consistent. Health experts recommend preschoolers get at least 10 to 13 hours of sleep, while those between six and 12 years should sleep for nine to 12 hours.
When you see these signs of weak immunity in your child, consult their paediatrician and take the necessary steps to turn things around immediately.
