Macronutrients, Micronutrients and Essential Nutrients.
Do We Need Them All?
Macronutrients
Needed in large amounts (grams). They provide energy (calories) or are major building blocks.
- Carbohydrates – main energy source.
- Proteins – build and repair tissues, make enzymes & hormones.
- Fats (Lipids) – long-term energy, insulation, absorb vitamins.
- Water – essential for all body processes (though it has no calories, it’s considered a macronutrient because we need a lot of it).
Micronutrients
Needed in small amounts (milligrams or micrograms). They don’t provide energy, but they regulate vital processes.
- Vitamins – organic compounds that regulate metabolism, immunity, and growth.
Examples: Vitamin A, B-complex, C, D, E, K.
- Minerals – inorganic elements important for bones, nerves, fluid balance, etc.
Examples: calcium, iron, zinc, potassium, iodine.
Active Ingredients
They are the specific chemical substances in a product that produce the intended effect in the body.
In medicines, the active ingredient is what actually treats the illness or reduces symptoms.
- Example: In aspirin, the active ingredient is acetylsalicylic acid (relieves pain and reduces fever).
In dietary supplements, the active ingredient is the nutrient or compound that provides the health benefit.
- Example: In a vitamin C tablet, the active ingredient is ascorbic acid.
In herbal products, the active ingredient can be a natural compound extracted from a plant.
- Example: In turmeric capsules, the active ingredient is curcumin.
In cosmetics/skincare, the active ingredient is the component responsible for the effect (like anti-aging or acne treatment).
- Example: In sunscreen, zinc oxide or titanium dioxide are active ingredients.
In short:
- Macro = carbs, proteins, fats, water (big amounts).
- Micro = vitamins, minerals (tiny amounts).
- Active ingredients = the part of a product that actually does the job it claims (healing, nourishing, protecting).
