Fat-soluble vs water-soluble.
Vitamins fall into two families. Fat-solublevitamins — A, D, E and K — are stored in the body’s fat and absorbed best alongside a meal; vitamin D is the classic example. Water-soluble vitamins — the B-complex and vitamin C — are not stored in large amounts, so they are needed more regularly.
Minerals such as magnesium, zinc, iron and calcium are a separate group, but they matter just as much. You can browse the full, evidence-based library of nutrient fact sheets at the NIH Office of Dietary Supplements.
Key nutrients, and what they do.
Here are some of the nutrients we build our formulas around — each with a trusted source to read further, and the Organica Living product where it takes centre stage.
Vitamin D3 — supports bones, immunity and calcium absorption; hard to get from food alone. Learn more · Optimus D3
Vitamin C — an antioxidant that supports immunity and collagen formation. Learn more · Vision Pro
Folate (B9) & B12 — vital for red blood cells and — during pregnancy — healthy neural development. Learn more · Bloom
Magnesium — involved in muscle and nerve function, energy and restful sleep. Learn more · Sleep Pro+
Zinc — supports immune function, skin and normal metabolism. Learn more · Multi Pro
Biotin — a B vitamin involved in keratin production for hair, skin and nails. Learn more · Glow Pro
Iron — carries oxygen in the blood; needs rise notably during pregnancy. Learn more · Bloom
Omega-3 (EPA & DHA) — essential fats — not vitamins — that support heart, brain and eye health. Learn more · Omega 1000
Where vitamins come from.
A varied diet delivers most of what you need — citrus and peppers for vitamin C, leafy greens for folate, oily fish for Omega-3, nuts and seeds for magnesium. Vitamin D is the notable exception: your skin makes it from sunlight, which is why so many people fall short in darker months and choose to supplement.
Helpful, in the right doses.
Supplements shine when diet, lifestyle or life stage leaves a gap — vitamin D in winter, folate and iron in pregnancy, B12 on a plant-based diet. The NIH Office of Dietary Supplements notes that a daily multivitamin/mineral can help cover common shortfalls. What matters is the dose: we formulate to clinically-meaningful amounts, third-party tested for accuracy.
“Food supplements should not be used as a substitute for a balanced diet and healthy lifestyle.”
