When a virus or bacteria enters the body, the immune system recognises it as foreign and produces the right cells, antibodies, and biochemical responses to eliminate the invader.

If you do a quick search for “immunity boosters” on the internet, you’ll find endless hacks from age-old home remedies to vitamin supplements and powders promising quick protection. Scroll through social media, and wellness influencers are ready with brightly coloured “immunity-packed” juice recipes, often without any scientific data to support their claims.
But is that really how immunity works? Can you actually boost it through external remedies and supplements?
To answer that, we first need to understand what immunity means scientifically — and what popular so-called “immunity boosters” like turmeric milk and vitamin pills truly do for your body.
What Immunity Really Means
“Immunity,” Dr Yogesh Valecha, Senior Consultant–Internal Medicine at Medanta Hospital, says, “is your body’s ability to identify and eliminate things that can harm you.”
He explains that the immune system is not a single organ. It is a network. It includes lymphatic glands spread across the body, white blood cells circulating in the bloodstream, antibody production mechanisms, and organs like the spleen that coordinate immune responses.

Can You “Boost” Immunity From Outside?
Here is where popular belief diverges from medical science. Dr Valecha says that immunity is primarily an internal biological process influenced by genetics, age, and overall health.
However, external factors do matter. Proper nutrition, adequate sleep, exercise, stress management, and vaccinations — all of these support immune function.
“Foods or supplements may support your immune system, but they won’t give you more than you naturally have,” he adds.
But foods and supplements do not give you “extra” immunity beyond your natural capacity.
“It is not a light switch,” he says. “It cannot be overstimulated — and should not be overstimulated.”
This is a critical distinction. Supporting immunity is not the same as amplifying it.
Does Turmeric Milk Work?
Turmeric milk has been India’s trusted preventive remedy for generations. From sore throats to seasonal infections, haldi doodh is often the first defence.
Dr Valecha explains that turmeric contains curcumin, known for its anti-inflammatory and antioxidant effects. These properties may indirectly support immune health by reducing inflammation. But he clarifies that turmeric does not necessarily prevent illness.
For those who want to consume turmeric, Dr Valecha advises drinking turmeric milk with black pepper in the evening, which may help your body absorb the curcumin better than taking large amounts of turmeric.
Are Mix Morning Juices Effective?
Green and red juices often carry the label of “immunity boosters.” Amla, beetroot, bottle gourd, and bitter gourd juices are packed with phytonutrients, vitamins, and antioxidants. Amla, in particular, is rich in Vitamin C, essential for immune cell function.
But these juices do not directly build immune cells. “They promote overall health, which indirectly benefits the immune system,” Dr Valecha explains. “They improve nutrition and reduce inflammation.”
That difference matters. Moderate consumption of fresh juices is safe for most people. But excessive intake can upset the stomach or spike blood sugar levels.
However, Dr Valecha says that Whole fruits and vegetables are much better for your immune system since they contain fibre, help your gut, and allow for slower absorption of nutrients.
Vitamin Pills: Necessary Or Overused?
Vitamin C, Vitamin D, and zinc supplements are among the most consumed immunity products today. These nutrients are indeed essential for immune cell function. However, their biggest benefit is seen in people.
“Extra supplements offer very little advantages for healthy individuals who have no deficiency in their bodies,” says Dr Valecha.
Routine supplementation should ideally follow laboratory testing or a doctor’s advice, he adds.
Preventive supplements are not required for most people consuming a balanced diet. The elderly, high-risk individuals, or those with confirmed deficiencies may benefit the most.
“Taking supplements blindly can result in excess supplements without adding an increased benefit to the immune system,” Dr Valecha says.
Excess Vitamin C can cause stomach discomfort. Too much zinc can interfere with copper absorption. High levels of Vitamin D can disrupt calcium balance.
Over-supplementing does not enhance immune strength — it may create new problems. Moderation and medical supervision matter.
Does Allergy Mean Weak Immunity?
Many people believe that those with allergies have weak immunity. Medically, this is incorrect. In fact, allergies indicate hypersensitivity — an immune system reacting too strongly, not too weakly. Someone with allergies may have a perfectly normal, even hyper-responsive immune system
“Allergies are not a sign of weak immunity,” Dr Valecha clarifies. “They reflect an overactive immune response to harmless substances like pollen or dust.”
So What Actually Works?
If immunity cannot be switched on with a drink or pill, what truly makes a difference is a healthy lifestyle. To maintain a healthy immune system, Dr Valecha advises 7–8 hours of quality sleep every night, regular physical activity balanced diet rich in fruits and vegetables.
He also underscores the importance of staying well-hydrated, managing stress effectively, and keeping vaccinations up to date. “Consistency in lifestyle choices,” he says, “matters far more than relying on occasional, quick-fix solutions.”
