Effects of Vitamin A over dose include fatigue, upset stomach, decreased appetite, vomiting, slow or decreased growth, joint soreness, irritability, hedache, drying and cracking of lips and skin, hair loss and yellowing of the skin. Excessive intake of Vitamin A during pregnancy can cause birth defects in the fetus.

* Vit B An overdose of B6- 250 to 1000mg can be toxic leading to nerve damage. There are no toxic effects noted for excessive intake of Vitamins B1 (thiamine) B2 (riboflavin) and B12 (cobalamine) but since B vitamins are interdependent, excess of one may produce deficiency of others.

B3 (niacin) at 3gm can cause aneroxia, abnormal glucose tolerance, gastric ulceration, excessive uric acid in blood, possibly leading to gout.

A high dose of potassium can lead to mental impairment, weariness, excessive potassium in the blood causing muscular paralysis and abnormal heart rythms.

B6 (pyridoxine) at 30mg can cause sensory and motor impairment. Dependency on high doses can lead to deficiency symptoms when one returns to normal dosage.

* Vitamin D at 10,000 IU can cause calcium deposits throughout the body, which maybe mistaken for cancer as well as deafness, kidney stones, fragile bones, high blood cholesterol and increased lead absorption.

* Vitamin E an overdose of vitamin E ( the body only needs 100 to 300mg of vitamin E per day) can lead to blood clots, fatigue, tumors in the breast and reproductive problems.

* Selenium at 750 micro gram can cause diabetes, garlic-breath odor, impairment of the immune system, loss of hair and nails, irritability, skin lessions, tooth decay, nausea, yellowish skin.

Note: cooking acid foods in unlined copper pots can lead to toxic accumulation of copper.

* Iodine at 2mg can lead to thyroid impairment, iodine poisoning or sensitivity reaction.

* Iron at 25mg can interfere with zinc and copper absorption and cause loss of appetite and toxic build-up in the pancreas and heart.

8 Folic acid at 15mg can cause loss of appetite and sleep disturbances and may interfere with zinc absorption.
