Chemically, baking soda is sodium bicarbonate ($NaHCO_3$), a compound that contains sodium but is fundamentally different from the pure, highly reactive element sodium itself. A single teaspoon of baking soda contains about 1,260 mg of sodium, yet it is a stable, safe household ingredient.

According to the National Institutes of Health, nearly half of Americans may have inadequate magnesium intake, making supplementation a common topic.

While the terms are often used interchangeably, ferrous and iron have distinct chemical meanings. Iron (Fe) is a chemical element, while 'ferrous' is an adjective used to describe materials or compounds that contain iron, often specifically in its +2 oxidation state.

Over 300 enzyme systems in the human body rely on magnesium, yet confusion persists over whether it is the same as salt. While related in many common compounds, magnesium is a pure chemical element, and salt is a broader term for ionic compounds, making them fundamentally different things.

Fresh cow's milk is typically about 87% water, yet its remaining 13% contains a complex array of different substances. Far from being a single compound element, milk is scientifically defined as a colloidal mixture composed of water, fats, proteins, carbohydrates, vitamins, and minerals. This article explains the chemical makeup of milk and why it's a prime example of a heterogeneous mixture.
