Common cold prevented and treated by Vitamin D, Vitamin C, Zinc, and Echinacea – review April 2018

Self-Care for Common Colds: The Pivotal Role of Vitamin D, Vitamin C, Zinc, and Echinacea in Three Main Immune Interactive Clusters (Physical Barriers, Innate and Adaptive Immunity) Involved during an Episode of Common Colds—Practical Advice on Dosages and on the Time to Take These Nutrients/Botanicals in order to Prevent or Treat Common Colds

Maintaining a normal healthy immune defense system lowers the incidence and/or the severity of symptoms and/or the duration of common cold (CC). Physical barriers and innate and adaptive immunity have been involved during a CC episode. Vitamins C and D, zinc, and Echinacea have evidence-based efficacy on these immune system barriers.

This review includes 82 eligible studies to consider the preventive role of these nutrients in immune clusters and in CC to provide advice on dosage and assumption of these nutrients. Regarding vitamin C, regular supplementation (1 to 2 g/day) has shown that vitamin C reduces the duration (in adults by 8%, in children by 14%) and the severity of CC.

Considering zinc, the supplementation may shorten the duration of colds by approximately 33%. CC patients may be instructed to try zinc within 24 hours of onset of symptoms.

As for vitamin D, the supplementation protected against CC overall, considering baseline levels and age. Patients with vitamin D deficiency and those not receiving bolus doses experienced the most benefit.

Regarding Echinacea, prophylactic treatment with this extract (2400 mg/day) over 4 months appeared to be beneficial for preventing/treating CC.

In conclusion, the current evidence of efficacy for zinc, vitamins D and C, and Echinacea is so interesting that CC patients may be encouraged to try them for preventing/treating their colds, although further studies are needed on this topic.

  • "In European populations, adults have from 2 to 5 infections annually, children typically present 6 to 12 “colds” per year, "

Observations by Henry Lahore, founder of VitaminDWiki

I am amazed that the study had very few datapoints for taking Zinc and Vitamin C every 2-3 hours

  1. Vitamin D
    Having a good level reduces the likelihood of CC (prevention) by about 20%
    A "vitamin D hammer" (50,000 IU, single dose appears to stop a cold (treatment) if taken within a day of the start of the cold
    Vitamin D Hammer
  2. Vitamin C
    Appears to be great for both prevention and treatment of CC
    Treatment: Take some Vitamin C every few hours after the start of cold
  3. Zinc
    The clinical trials using Zinc lozenges every 2 hours found great success when started within a day of the start of the cold
  4. Echinacea
    Appears to be useful for prevention and perhaps treatment - no personal experience
  5. UVC germ killer
    Family and friends have found that a UV sterilizer kills the air-borne cold germs
    UVC both reduces the cold duration AND reduces the risk of a family member "catching" the cold
    • We have purchased two Germ Guardians - they cost $35 each and are almost silent
    • We have loaned out the cleaners so many times that we have put our phone number on them so they get returned

Update Dec 2018
My daily bulk supplements now include Zinc (1/3 of a cent per day)
So far ZERO colds this season

No indication that adults were also giving vitamin D to thier children, who are typically the sorce of colds in a household - see chart below
