Why does excess Vitamine C and Omega's motivation Nose Bleeds?

I'm trying to verify and get a better grasp about these diet supplements. Wikipedia which say:
http://en.wikipedia.org/wiki/nose_bleed#.
"Some people who own frequent nosebleed problems, the cause could be the effect of vitamin overdose especially vitamin C .
Cultures near a diet rich in fish sources that include soaring levels of omega-3 fatty acids (especially the Inuit) enjoy also been observed to experience a better incidence of nosebleeds. Athletes and bodybuilders who supplement their diets with fish grease also report increased frequency of nosebleeds." Vitamin C or Ascorbic Acid is an acid which have some anti-coagulant properties, or it makes the consistency of blood thinner , thus it is attributed to do nosebleeds in trustworthy patients who may be sensitive to this drug. As for omega-3 fatty acids I would say like property as cited for Vitamin C and normally fatty acids do counter in our systems scantily especially if we take them on an void stomach. Same case for Vitamin C.
I don't enjoy a good answer. I do purloin both as supplements. But have never have a nose bleed.
Blood thinners.
Wikipedia is wrong! Vitamin C and Omega Fatty Acids do not explanation nosebleeds. The most typical reasons for nosebleeds are:
1) Dry nouns which causes the mucus to go hard.
Bleeding follows when nose is picked.
2) High blood pressure
3) Injuries
4) Allergies
5) Drugs that are snorted
I thought it be because they thin out the tissues within your nose. which cause easy bleeding.
