Fat-soluble vitamin important for vision, immune function, and cell division. Exists in two forms: retinol (animal) and beta-carotene (plant-based).

Thiamine — a water-soluble vitamin essential for carbohydrate metabolism and nerve function. Deficiency can cause beriberi.

Vitamin B12 (cobalamin) is a water-soluble B vitamin essential for nerve function, red blood cell formation, and DNA synthesis. Deficiency is common among vegans and the elderly.

Riboflavin — a water-soluble vitamin essential for energy production and a cofactor for many enzymes. Causes yellow colouration of urine.

Niacin — water-soluble vitamin important for energy metabolism, DNA repair, and cholesterol regulation. Exists as nicotinic acid and nicotinamide.

Pantothenic acid — involved in CoA synthesis, essential for fatty acid metabolism and hormone production.

Vitamin B6 (pyridoxine) participates in 150+ enzymatic reactions. Important for amino acid metabolism, serotonin production, immune function, and haemoglobin formation.

Biotin — a water-soluble vitamin known for its role in hair, skin, and nail health. Also supports fatty acid and glucose metabolism.

Vitamin C (ascorbic acid) is a water-soluble vitamin and a powerful antioxidant. It supports the immune system, collagen production, iron absorption, and protects cells against oxidative stress.

Water-soluble antioxidant and cofactor that supports all levels of the immune system. Especially important during infection and stress.

Vitamin D is a fat-soluble vitamin produced in the skin upon sun exposure. It is crucial for calcium absorption, skeletal health, and the immune system. Deficiency is common in Scandinavia during the winter months.

Steroid-like vitamin that affects testosterone production via vitamin D receptors in the testes. Most people in the Nordic countries have a deficiency.

Vitamin D3 (cholecalciferol) is the most effective form of vitamin D. It is naturally produced in the skin upon sun exposure and is found in animal-based foods. It provides a better and longer-lasting increase in blood levels than D2.

Powerful fat-soluble antioxidant that protects cell membranes from oxidative stress. Important for immune function and skin health.

Fat-soluble vitamin that regulates calcium metabolism — directs calcium to bones and teeth instead of blood vessels. Synergistic with D3.
