Vitamins to Avoid if You Are Sick

Type 2 diabetes

Osteoporosis

People suffering from osteoporosis should avoid vitamin A and phosphorus.

Vitamin A is responsible for maintaining healthy skin, skeletal and soft tissue, teeth and it produces the pigment found in the retina. However, high doses of vitamin A can lower bone density. High levels of phosphorus can also cause calcium to leave the bones.

Stomach Ulcers

If you are having stomach ulcers you should avoid vitamin A.

When an individual is suffering from a stomach ulcer the doctor will prescribe antibiotics to combat the Helicopter pylori, which causes the ulcers. Vitamin A can help restore the stomach lining; however, too much vitamin A can lead to an increase in brain pressure, headaches, visual disturbances and vomiting.

Heart Problems

If you are suffering from heart complications you should avoid vitamin E and potassium.

A seven-year study, conducted by researchers from McMaster University in Ontario, demonstrates that high doses of vitamin E are associated to a higher risk of heart failure.

Additionally, high doses of potassium could lead to irregular heartbeats and heart palpitations.

Prostate Cancer

If you have prostate cancer you should avoid high doses of calcium.

Hormone therapy for prostate cancer is a treatment to stop your body from producing the male hormone testosterone. It is also weakens the bones, increasing your risk of bone fractures. Although calcium is important for bone health, researchers from Wake Forest Baptist Medical Center, North Carolina, found that consuming too much calcium during hormonal therapy can have an adverse effect on vitamin D.

According to Professor Powers, vitamin D is essential for the body to absorb calcium.
If too much calcium works as a lowering effect on active vitamin D, then the process thwarts any effect calcium would have had on an individual's bones.
