You don't have to have full blown Scurvy to be lacking ample vitamin C fortification.
Vitamin C supports collagen production. Collagen literally holds you together! Really! Over time, a lack of vitamin C means that new collagen cannot be formed. This causes a break down in collagen dependent soft tissue. There will be issues with the quality of your skin, tendons, ligaments and muscles when vitamin C is lacking. This is certainly information that athletes, exercise enthusiasts and those that care about the appearance of their skin should take to heart among others...
A diet rich in fruit and vegetables does not mean it is rich in enough vitamin C, nor is a diet low in vitamin C the only reason for a sub clinical deficiency. The following may be at higher risk of being too low:
 
- 
Those struggling with gut disorders notoriously can't absorb nutrients efficiently
 - 
SMOKERS, prescription/recreational drug users and excessive alcohol drinkers require more vitamin C.
 - 
Adrenal fatigue sufferers
 - 
Those that are anemic
 - 
Those suffering with a thyroid condition
 - 
Extreme dieters
 - 
Picky eaters
 - 
Pregnant/breast feeding women
 
The following can be symptoms of vitamin C deficiency:
 
- 
multiple infections that do not resolve on their own
 - 
poor wound healing
 - 
high blood pressure ( collagen is necessary for the integrity of the blood vessel walls)
 - 
fatigue
 - 
muscle and joint pain
 - 
bleeding under the skin, presenting as reddish bruises
 - 
swollen/bleeding gums
 - 
autoimmune disorders
 
An immune system weakened by a lack of vitamin C over time, is susceptible to chronic disease.
