A weak immune system is an invitation to viral and bacterial infections
Supplements like vitamin C and adaptogens are the best immunity boosters
The immune system’s primary function is to fight against pathogens like toxins, viruses, and bacteria that invade the body. We require a healthy intake of protein, minerals, micronutrients, and vitamins to strengthen our immune system. Unfortunately, food adulteration, malnutrition, lack of nutrients in the soil, and an unhealthy diet lead to such deficiencies.
A weak immune system is an invitation to frequent viral and bacterial infections. It increases other health risks like HIV/AIDS, viral hepatitis, leukemia, and cancer. Some people suffer from immune disorders from birth, while others may develop it later due to environmental and other factors. However, there are certain supplements to boost the immune system that can truly help.
