Vitamins and minerals are essential, in a very small amount; for healthy growth
and development. They cannot be synthesized in the body. The body only
utilizes them without breaking them down, which is the reason why they are
only required in "small amounts".
Vitamins and nutrients are often regarded as wonder nutrients and are thus
normally believed to be free from side effects.However vitamin overdose may
cause discomfort and other potentially serious damage to the body.
Vitamins are usually separated into water-soluble (e.g., the B vitamins,
vitamin C) and fat-soluble (e.g., vitamins A, D, E, K) groups.
Vitamins overdose of vitamin B and C are excreted in the body but fat-soluble
vitamin overdose tend to accumulate and eventually cause poisoning when
high levels of concentration in the body have been reached.
Each vitamin also has specific symptoms associated with its vitamin
overdose. The good news is that morbidity and mortality from pure vitamins
overdose are rare. One study of acute or chronic vitamin overdoses, with more
than 40,000 exposures, reported 1 death and 8 major adverse outcomes.
Vitamin A overdose can cause headache, nausea, diarrhea, dry itchy skin,
hair loss and loss of appetite. Fatigue and irregular menstruation are common.
In extreme this vitamin overdose there can be bone pain and enlargement of
liver and spleen. High doses of beta carotene may turn the skin yellowish
orange. Meanwhile, vitamin A overdose in pregnancy may lead to birth defects.
Vitamin D overdose may lead to calcium deposits in soft tissues, blood
vessels walls and kidneys. In children this will cause growth
retardation.Musculoskeletal effects include pain and tenderness, particularly in
the long bones of the upper and lower extremities, which may be exacerbated
by exercise; epiphyseal capping and premature epiphyseal closure, may occur
in children. Neurological effects include blurred vision and frontal headache,
craniotabes in children, or bulging fontanelle in infants.
Chronic vitamin D overdose effects include the above symptoms and
constipation, anorexia, polydipsia, polyuria, backache, hyperlipidemia, and
hypercalcemia followed by hypertension and cardiac arrhythmias.
Vitamin E overdose causes nausea, headache, fatigue, easy bruising and
bleeding muscle weakness, and creatinuria.Chronic vitamin E overdose effects
include all of the above, suppression of other antioxidants, and increased risk of
hemorrhagic stroke.
Vitamin K overdose typically associated with formula-fed infants or those
receiving synthetic vitamin K-3 (menadione) injections. Because of its toxicity,
menadione is no longer used for treatment of vitamin K deficiency. Effects may
include jaundice in newborns, hemolytic anemia, and hyperbilirubinemia.
Most adults can obtain enough vitamins by eating a well-balanced diet. It
has, however, become increasingly common for people to take vitamins at
levels far greater than the recommended dietary allowance RDA.
Balanced amounts of each and every vitamin in the body should be properly
followed, as an excessive in take of one vitamin can adversely affect the body's
use of another vitamin even though the second vitamin is present in normal
amounts.
For instance, deficiency in vitamin K is attributed by large amounts of
vitamin E. Vitamin E overdose changes the body's need for vitamin K to the
point of causing vitamin K deficiency. Vitamins and minerals function as
partners and technically termed as "cofactors" in the metabolism of products in
the bodyFor more info visit onlinenaturalvitamins.com

Risk Assessment Vitamin D
This paper sets out the research and safety issues regarding Vitamin d and suggests that 40,000iu/d for some months is needed before adverse events are observable.
In practice therefore 10,000iu/daily should be regarded as a safe upper limit. That said it is clear that as the body only uses between 3000 and 5000iu daily even 10,000iu/d is a larger amount than is necessary for everyday use although it could be reasonable to rectify a deficiency in the short term. For all practical purposes 4000iu/d is ample for people who cannot get outside into the sunshine when their shadow is shorter than their height.
If you are able to get hands/face exposure to sunlight then perhaps 2000iu/d would raise your status from the current average of around 75nmol/L to the ideal 125nmol/L that is associated with 50% less breast cancer.
