I think if you started feeling symptoms it wouldn't do much harm to start taking 2-3 grammes of vitamin c, I'd probably do that. A few months back I started to feel like a sore throat was developing, that lurgy feeling, so I had a couple of those vit C drinks and the following day my throat cleared and I never came down with anything. It was probably only going to be a mild cold but still the vit C seemed to do something.
Vitamin C has also been investigated to see whether it can help with psychiatric disorders, like anxiety etc..

Our brain is a power consumer of vitamin C, the vitamin that cuts your colds short. Brain concentrations of the vitamin are far greater than those in the rest of the body, and long after the body is depleted of the vitamin, the brain maintains its levels. That's partly because the metabolic furnaces in neurons churn through glucose to power all your thoughts and feelings and movements, and as an antioxidant, the vitamin's job is to surrender electrons to neutralize rogue oxygen molecules given off in the process—free radicals that damage
and generally age your cells. But vitamin C also does more, and some 80 years after its discovery, its additional roles are just coming to light.
Chief among them are actions in the nervous system. Vitamin C plays a role in the differentiation and maturation of neurons and in the formation of the myelin sheath that protects them and speeds impulse transmission,
making the vitamin crucial to cognitive performance. It is a cofactor in the synthesis of several neurotransmitters,
it's needed to convert dopamine to serotonin, and it modulates neurotransmitter release in nerve cells. And while it's long been known that the vitamin is a component of collagen, a stabilizing force for teeth, bones, and blood vessels,
only now is its role in ensuring blood vessel integrity seen as a factor in cognitive capacity, especially as we age.
#Regular intake of vitamin C attenuates colds, shortening their duration and severity.
#High levels of vitamin C intake are linked to a lessened chance of developing eye cataracts and macular degeneration. [interesting, I thought vit A was important for eyesight]
