There’s no cure yet for the common cold, but you may be able to shorten the amount of time you’re sick by trying some promising supplements and practicing good self-care.
Stroll the aisles of any drugstore and you’ll see an impressive range of products claiming to shorten the length of your cold. Few of them are backed by solid science. Here’s a list of remedies known to make a difference in how long colds last:
Taking a vitamin C supplement isn’t likely to prevent a cold. However, studies show that it may reduce the duration of colds. A 2013 review of studies noted that regular supplementation (1 to 2 grams daily) reduced the duration of a cold in adults by 8 percent and in children by 14 percent. It also reduced the severity of colds overall.

Some people who take echinacea report unwanted side effects, such as nausea and diarrhea. Talk to your doctor before trying echinacea to confirm it won’t interfere with any other medicines or supplements you’re taking.

Cold symptoms like coughing, sneezing, runny nose, congestion, sore throat, and headache can make it hard to function during the day and hard to rest at night.
Decongestants, pain relievers like ibuprofen or acetaminophen, cough suppressants, and antihistamines can treat symptoms so you feel better faster, even if the viral infection lingers. Check with a pediatrician before giving your child any over-the-counter medicine.
Drinking plenty of fluids is always good when you’re trying to get rid of a cold. Hot tea, water, chicken soup, and other liquids will keep you hydrated, especially if you have a fever. They can also loosen congestion in your chest and nasal passages so you can breathe.
Avoid caffeine and alcohol, though, because they can leave you dehydrated, and they can interfere with the sleep and rest you need for recovery.
When to go to the doctor
Colds that don’t go away quickly can lead to other illnesses like pneumonia, lung infections, ear infections, and sinus infections. See your doctor if :
- your symptoms last longer than 10 days
- you have a fever over 101.3°F (38.5°C)
- you begin vomiting violently
- your sinuses ache
- your cough begins to sound like a wheeze
- you feel pain in your chest
- you have trouble breathing
At the first sign of a cold, most of us want to make sure the sniffles, sneezing, and other symptoms go away as quickly as possible.
If you take vitamin C regularly, your cold symptoms may disappear earlier. And there is some scientific support for trying remedies like zinc, echinacea, elderberry preparations, beetroot juice, and probiotic drinks to prevent or shorten the duration of a cold.
The best way to beat a cold fast is to rest, drink lots of fluids, and treat the symptoms with medicines that relieve pain, coughing, and congestion.
