Can vitamin C or Echinacea help you get over a cold faster?
While there’s been a lot of interest in the role of vitamin C and Echinacea in cold recovery, repeated studies have not shown any clear association between their intake and a speedier recovery. What’s more, Echinacea products can be problematic since these items are not currently regulated by the FDA. This situation has sometimes spurred questions of both safety and purity; these include the possible presence of filler ingredients, or processing contaminants that might be damaging to health.
Slurping down vitamin C rich orange juice and other citrus fruits while you’re sick won’t hurt, but experts say it isn’t a cure-all either. In fact, downing high doses of vitamin C (in products like supplements) can actually be a risky move since hefty amounts of the mineral (above 2000 mg a day) can spur an upset stomach and may actually interfere with the absorption of other health-enhancing vitamins and minerals, setting back a smooth recovery.
