Vitamins
Overview:
Most people do not need to take a multi-vitamin.
Most vitamins can be obtained through a healthy diet.
Fat-soluble vitamins can be toxic in large doses: Vitamins A, D, E, K.
Water-soluble vitamins can be eliminated via urine; generally not toxic.
Fat-Soluble Vitamins
Vitamin A:
Essential for bone growth, epithelial tissue, skin, eyes, and hair.
Deficiencies can lead to blindness.
Loss of night vision is an early warning sign for Vitamin A deficiency.
Vitamin D:
Major role in calcium and phosphorus metabolism.
Often provided as a combination pill with calcium.
Can be obtained from sunlight; individuals without adequate exposure are at risk of deficiency.
Vitamin E:
Possesses antioxidant properties, protects cellular components and red blood cells (RBCs).
Caution: Do not take Iron and Vitamin E together as this can impair absorption.
Vitamin K:
Necessary for synthesis of clotting factors and prothrombin.
Administered to newborns at birth for this reason.
Acts as an antidote to warfarin (Coumadin, Jantoven).
Water-Soluble Vitamins
B Complex Vitamins:
Vitamin B1 (Thiamine):
Deficiency often seen in alcoholism; can affect short-term memory.
Vitamin B2 (Riboflavin):
Deficiencies often lead to dermatological issues.
Vitamin B3 (Niacin):
Decreases hyperlipidemia; may cause gastrointestinal upset.
Vitamin B6 (Pyridoxine):
Necessary for synthesis of RBC/hemoglobin; often administered due to drug-induced deficiencies.
Vitamin C:
Aids in iron absorption and conversion of folic acid.
Does not prevent colds, despite common belief.
Can decrease the effects of anticoagulants.
Folic Acid (Folate):
Essential for body growth, particularly for pregnant women/fetuses.
Caution in patients taking phenytoin for seizures (lower levels can increase risk of seizures).
Vitamin B12:
Assists folic acid in converting to its active form in the body.
Promotes cellular division; crucial for RBC development.
Gastric parietal cells produce an intrinsic factor essential for absorption.
Lack of intrinsic factor may necessitate intramuscular (IM) administration of B12.
Alternative and Complementary Therapies
Black Cohosh Root:
Exhibits estrogen-like properties.
Used for premenstrual syndrome (PMS) and menopausal disorders.

Breaks up respiratory secretions; functions as a bronchodilator.
Relieves anxiety.
Chondroitin:
Used for osteoarthritis; usually combined with glucosamine.

Eucalyptus:
Suppresses cough; decreases respiratory secretions; highly toxic in children.

Green Tea Leaf:
Acts as an antioxidant; may prevent cancer and cardiovascular disease; enhances cognitive function.
Additional Alternative and Complementary Therapies
Lavender:
Treats insomnia and restlessness.
Caution advised when using with central nervous system (CNS) depressants; oil may be potentially poisonous.
Licorice:
Acts similarly to aldosterone.
Can block effects of spironolactone; may lead to digoxin toxicity.

Serious reactions possible with SSRIs, MAOIs, digoxin, theophylline, AIDS antiviral drugs, sympathomimetics, antineoplastics, and hormonal contraceptives.
Turmeric:
Known for its antioxidant and anti-inflammatory properties.
Commonly used to treat arthritis.
