Some traditional diets described in the Blue Zones feature vegetables, beans, whole grains, nuts and other nutrient-rich foods. Explore the nutrients behind everyday functions—and when a supplement might be worth discussing. Each card links to an Amarante guide.
MgINGREDIENT GUIDE
Magnesium
Muscle & nerve function
Supports normal muscle and nerve function, blood-pressure regulation and bone formation. A supplement may be relevant when intake is insufficient.
Food first: Seeds, beans, greens.
Food first; certain medicines and kidney disease change safety.

Omega-3
Heart & cell membranes
ALA is essential; EPA and DHA are components of cell membranes. Eating fish can support a heart-healthy dietary pattern. High-dose triglyceride treatment is medical care, not a longevity shortcut.
Food first: Fish, walnuts, chia, flax.
Fish oil is not proven to make healthy people live longer.

Vitamin D
Bone & muscle health
Helps absorb calcium and supports bone and muscle function. Adequate intake matters, especially in people at risk of deficiency.
Food first: Fortified foods, fish, eggs.
High doses are not automatically better.
Explore Vitamin D ↗K₂INGREDIENT GUIDE
Vitamin K2
Bone biology
Vitamin K is needed for normal blood clotting and proteins involved in bone health. K2 supplements have not been shown to prevent ageing.
Food first: Fermented foods, cheese; greens supply K1.
Consult a clinician before changing vitamin K intake when using warfarin.

Vitamin C
Tissue repair & antioxidant function
Essential for collagen formation, normal immune function and protecting cells from oxidative damage. Benefits from extra doses beyond adequacy are less certain.
Food first: Citrus, peppers, berries.
Megadoses are not a substitute for a varied diet.
Explore Vitamin C ↗SeINGREDIENT GUIDE
Selenium
Thyroid & antioxidant enzymes
Supports thyroid hormone metabolism and antioxidant enzymes. Deficiency matters; excessive supplemental selenium can be harmful.
Food first: Seafood, eggs, grains, Brazil nuts.
More is not better; Brazil nuts can supply very high amounts.
Explore Selenium ↗QINGREDIENT GUIDE
CoQ10
Cellular energy
Naturally present in cells and involved in mitochondrial energy production. Supplement studies target specific conditions, but longevity benefits have not been established.
Food first: Fish, meat, nuts.
No convincing evidence that routine CoQ10 supplementation extends lifespan.
Explore CoQ10 ↗CuINGREDIENT GUIDE
Curcumin
Plant compounds under study
The main curcuminoid in turmeric is being studied for inflammatory pathways. Human trials do not establish that supplements prevent ageing or chronic disease.
Food first: Turmeric in food.
Some concentrated products have interaction and liver-safety concerns.
Explore Curcumin ↗QnINGREDIENT GUIDE
Bio Quercetin
Plant flavonoids
Quercetin occurs in fruits and vegetables and is being researched for cellular effects. Clinical benefits from supplemental formulations remain uncertain.
Food first: Onions, apples, berries.
Absorption claims do not prove better health outcomes.
Explore Bio Quercetin ↗SaINGREDIENT GUIDE
SAMe
Methylation pathways
SAMe is a compound the body makes and uses in biochemical reactions. It is studied for several conditions, not for increased lifespan.
Food first: Made by the body.
May interact with antidepressants; avoid assuming it is a routine wellness supplement.

Vitamin B12
Blood, nerves & DNA
Needed for healthy nerve and blood cells and DNA formation. Low B12 can cause anaemia and neurological problems; risk of poor absorption rises with age.
Food first: Fish, eggs, dairy, fortified foods.
Plant-only diets need a reliable fortified food or supplement source.
Explore Vitamin B12 ↗CaNEW GUIDE
Calcium
Bones & muscle movement
Needed for bone strength, muscle contraction and nerve signalling. The priority is adequate total intake; whether extra calcium supplements prevent fractures is less certain.
Food first: Dairy, calcium-set tofu, greens.
Consider total intake and individual risk before supplementing.
Explore Calcium ↗KNEW GUIDE
Potassium
Blood pressure & nerves
Helps with normal fluid balance, nerve signals and muscle contraction. Potassium-rich foods alongside less sodium can support healthy blood pressure.
Food first: Beans, potatoes, vegetables, fruit.
High-dose supplements can be dangerous with kidney disease or certain medicines.
Explore Potassium ↗FiNEW GUIDE
Dietary fibre
Gut & metabolic health
Fibre supports bowel regularity. Soluble fibre can help lower LDL cholesterol; fibre-rich foods are also important components of healthy dietary patterns.
Food first: Beans, lentils, oats, fruit, vegetables.
A fibre supplement can help a specific gap but does not replace whole foods.
Explore Dietary fibre ↗B₉NEW GUIDE
Folate (B9)
Cell growth & DNA
Folate supports DNA synthesis and cell division. Adequate intake is essential; high supplemental folic acid can conceal B12-related anaemia.
Food first: Leafy greens, lentils, fortified grains.
High-dose folic acid is not a proven longevity therapy.
Explore Folate (B9) ↗PrNEW GUIDE
Probiotics
Specific gut effects
Certain well-studied strains can help in particular digestive conditions; effects depend on the exact organism and situation. No universal healthy-ageing effect has been shown.
Food first: Some live-culture yogurts, fermented foods.
Not all fermented foods contain proven probiotic strains.
