Immune System
The immune system depends on a range of specific nutrients to function as it should, with zinc, vitamin D and vitamin C among the most well-studied. Needs can increase during periods of high demand, seasonal shifts, or limited sun exposure. These supplements are intended to support an already-functioning immune system, not as treatment for infection or illness.
Frequently asked questions
Should immune supplements be taken year-round or just in winter?
The need for certain substances, like vitamin D, often increases during the winter months due to less sunlight, while others like zinc may be relevant year-round.
Can you take too much zinc?
Yes, prolonged high zinc intake can affect the absorption of other minerals like copper. Stick to the product's recommended dose.
Does vitamin C cure a cold?
No. Vitamin C is studied for its role in normal immune function, but is not a treatment or cure for infection.
