Flu season: what really helps and how to think about zinc and vitamin D

For information only. Products do not replace diagnosis, treatment or a varied diet. Seek professional advice for symptoms, pregnancy and use by children.

No supplement guarantees that you will not catch flu. As a first step, the CDC recommends a yearly flu vaccine for everyone over six months, especially young children, pregnant women, people over 65 and those with chronic conditions. Simple daily habits come on top of that.

Daily habits according to the CDC

1. Wash your hands often with soap and water, and use alcohol gel when soap is not available.
2. Do not touch your eyes, nose and mouth with unwashed hands.
3. Cough and sneeze into a tissue, then throw it away.
4. Stay home when ill, until symptoms improve and you have had no fever for at least 24 hours without medicine.
5. Air rooms and avoid close contact with sick people.

You can compare Aloe Liquid Soap as a mild liquid soap for frequent hand washing during the season, without any claim that it protects against flu. Apply a hand cream after washing if your hands get dry.

Zinc, vitamin D and probiotics

Foods such as meat, fish, eggs, legumes, nuts and fermented dairy supply some of these nutrients. The NIH Office of Dietary Supplements lists an upper limit for zinc of 40 mg a day for adults from all sources, and too much can be harmful. Start vitamin D and probiotics only on the advice of a doctor or pharmacist, especially if you take medicines, are pregnant or have a chronic condition.

When to see a doctor

If you have difficulty breathing, chest pain, confusion, a high fever that does not come down, or you are in a risk group, contact a doctor early. Antiviral medicines work best when started early, but a doctor must prescribe them.
