Emergen-C recommends taking one packet per day for adults aged 14 and up. Each packet contains 1,000 mg of vitamin C, which is half of the tolerable upper intake level (UL) of 2,000 mg per day for adults, making one packet daily a safe dose for most people
. It is advised not to exceed two packets per day to avoid potential side effects such as nausea, diarrhea, and abdominal pain caused by excessive vitamin C intake
. Additionally, high intake of other vitamins in Emergen-C, like vitamin B6 and zinc, should be monitored to avoid adverse effects
. In summary, the typical recommended daily usage is:
- One packet per day for general immune support
- Do not exceed two packets per day to stay within safe vitamin intake limits
If you are taking other vitamin supplements or medications, or have specific health conditions, consult a healthcare provider before use
