- a 1000 mg/ natural source. 1,100/synthetic source
- b antioxidant- stops damage done by free radicals (because it donates an electron to the free radicals), reduces oxidative stress
- c Age, Sunscreen/sunblock, darker skin tones, geographic location, season.

- Antibiotic therapy (disrupts making of vit by bacteria in colon). Fat free diet (absorption problem). Hemorrhagic disease of newborns (shot at birth)
- vegtable oil, margarine, shortening, wheat germ, whole grains, seeds, nuts (animal fats are NOT good sources)
- poorly formed new bone (weak or soft bone)
- Rickets (improper bone formation), Osteomalacia (poorly formed new bone)
- vitamin E deficiency. Red blood cells are broken down faster than they can be replaced.
5 True/False questions
Hypercalcemia → poorly formed new bone (weak or soft bone)
Functions of vitamin D → Rickets (improper bone formation), Osteomalacia (poorly formed new bone)
Hemmorrhagic diesase → vitamin K deficiency in new borns (given shot at birth)
Vitamin E (transportation) → from liver via lipoproteins (very low lipoproteins). Excreted in bile, urine, and skin.
Vitamin E (storage) → stored in fat or goes back to liver. Liver can make it inactive and it can circulate in blood stream for weeks. Small amount excreted in urine and bile.
