Vitamins are organic chemical compounds that an organism requires to maintain bodily functions but cannot synthesize within the body. These 15 vitamins are noted as essential in human biology and must be consumed from dietary sources.

Vitamin A

Fat soluble, for optimal absorption pair with foods that have a moderate fat content. See: Fatty Acids for a breakdown of healthy fats and where to find them. Vitamin A deficiency can lead to blindness and weakened immune system.

Retinoids, found only in meat and animal product foods, support immune, genetic, and reproductive health.

Foods with highest retinoid vitamin A content
  • Shrimp
  • Eggs
  • Cow’s milk and cheese
  • Yogurt
  • Salmon
  • Sardines
  • Chicken and turkey
  • Tuna
  • Cod
  • Scallops

Carotenoids, found in plants, have antioxidant and anti-inflammatory properties. Carotenoid nutrients Lutein and Zeaxanthin support eye health and ocular function.

Foods with highest Lutein and Zeaxanthin content
  • Spinach
  • Kale
  • Chard
  • Collards
  • Turnip greens

Under certain conditions, the body can convert alpha-carotene, beta-carotene, and beta-cryptoxanthin, from carotenoid into retinoid form. For essential Vitamin A retinoids in a diet without animal products, beta-carotene provides the most efficient conversion ratio.

Vegetarian foods with highest beta-carotene content
  • Sweet potatoes
  • Carrots
  • Greens (spinach, kale, mustard greens, collards, turnip greens, chard, romaine lettuce, bok choy)
  • Winter squash
  • Cantaloupe

  • Broccoli and asparagus
  • Sea vegetables
  • Herbs (parsley, chili pepper, basil)
  • Tomato

Vitamin D

Regulates blood sugar and promotes skeletal, exocrine and immune system health. Vitamin D deficiency increases risk of respiratory infection and diabetes, and can lead to a condition known as Rickets (in adolescents) or Osteromalacia (in adults), characterized by bone weakness and skeletal deformity. Certain forms of Vitamin D can be absorbed in the skin from sunlight, but dietary supplementation is necessary to utilize its full range of circulatory and immune system benefits.

  • Orange juice

Vitamin D is fat soluble, for optimal absorption choose food sources with a moderate fat content, or pair with foods rich in healthy fats. Commonly known to build strong bones, what Vitamin D giveth, Vitamin D may taketh away to compensate for insufficient Calcium levels in the blood. To preserve bone health, pair Vitamin D with foods rich in Calcium. Dairy products, naturally rich in Calcium, are often fortified with Vitamin D.

Vitamin E

Fat soluble, and a strong antioxidant, Vitamin E protects the fats lining cell membranes from damage by free radicals. Vitamin E deficiency can impair its ability to protect cholesterol from oxidation, causing it to accumulate and harden in the arteries, leading to a condition known as Atherosclerosis.
