Iron is an essential mineral that plays a critical role in oxygen transport in the blood. It is crucial for energy production and immune function. Iron from plant sources is non-heme, which is less readily absorbed than heme iron from animal sources.

Calcium is vital for maintaining strong bones and teeth. It also plays a role in muscle function and nerve signaling. Plant-based calcium sources may have lower bioavailability compared to dairy sources.

Potassium is a key mineral that helps regulate fluid balance and muscle contractions. It is important for maintaining healthy blood pressure levels. Potassium from whole foods is generally well-absorbed and beneficial.

Magnesium is essential for over 300 biochemical reactions in the body, including energy production and muscle function. It is important for bone health and maintaining normal nerve function. Whole food sources of magnesium are generally well-absorbed.

Selenium is a trace mineral that plays a critical role in antioxidant defense and thyroid hormone metabolism. It is important for immune function and may help protect against oxidative stress. Whole food sources of selenium are typically well-absorbed.

Zinc is an essential mineral important for immune function, wound healing, and DNA synthesis. It plays a role in taste and smell and is crucial for growth and development. Zinc from plant sources may have lower bioavailability compared to animal sources.

Folic acid, or Vitamin B9, is crucial for DNA synthesis and repair. It is especially important during periods of rapid growth, such as pregnancy and fetal development. Folic acid from supplements is more bioavailable than folate from food sources.

Vitamin B12 is essential for nerve function and the production of DNA and red blood cells. It is primarily found in animal products, making supplementation important for vegetarians and vegans. Vitamin B12 from supplements is well-absorbed and effective.

Biotin, or Vitamin B7, is important for energy metabolism and the health of hair, skin, and nails. It acts as a coenzyme in the metabolism of fatty acids and amino acids. Biotin from whole foods is generally well-absorbed.

Pantothenic acid, or Vitamin B5, is essential for the synthesis of coenzyme A, which is involved in fatty acid metabolism. It supports energy production and the synthesis of hormones and neurotransmitters. Whole food sources of pantothenic acid are typically well-absorbed.
