Vitamin C is a great winter vitamin to get to know, as we approach cold season!

Studies have shown that taking Vitamin C does not decrease the average incidence of colds in the general population, but it cut the number of colds in physically active people in half.  Taking 6-8 grams of Vitamin C daily has been shown to shorten the duration of colds.  This is a large dosage, which translates into 6000-8000 mg per day.  Vitamin C levels are also decreased during a common cold, influenza, and other infections, making it important to replenish. Vitamin C is much more abundant in the white blood cells than in the blood plasma, which is why it is believed to have such a great immune response. Higher dosages of Vitamin C in both children and adults were associated with a stronger response. (Source)


Vitamin C is water soluble, meaning it is able to dissolve in water.  As a result, it doesn’t interact inefficiently with the cell membrane wall.  Taking Vitamin C orally only has a 20% absorption rate into the bloodstream, and 80% remains in the colon, which can cause cramping and digestive issues.

Liposomes carry nutrients to our body’s cells.  “Lipo” is Greek for fat, and “soma” means body.  Liposomal vitamin C is able to pass through the digestive barrier to deliver the Vitamin C right to the bloodstream, making the bioavailability much higher than taking it orally.  (Source)




There are two products that I recommend for winter Vitamin C, both are bioavailable sources of Vitamin C.  If you come down with a cold, remember that high doses work best!  Cancer patients also use Vitamin C in very high dosages, up to 10,000 mg a day for treatment.

These packets are added to water and you drink it. They are not too messy and pretty easy to drink, with 1000 mg or 1 g per packet.

If you prefer to swallow a capsule, these are also 1000mg or 1g and I recommend this brand by Dr. Mercola.
