Turmeric / Curcumin
Also known as: Curcumin, Curcuma longa, Indian Saffron, Golden Spice
Turmeric is a golden-yellow spice derived from the root of the Curcuma longa plant. Curcumin is its primary active compound, responsible for most of its medicinal properties. Used for thousands of years in Ayurvedic and traditional Chinese medicine, curcumin has powerful anti-inflammatory and antioxidant effects that are now being validated by modern research.
Benefits
Potent anti-inflammatory properties — may be as effective as some anti-inflammatory drugs for joint pain. Strong antioxidant that neutralizes free radicals and stimulates the body's own antioxidant enzymes. May improve symptoms of osteoarthritis and rheumatoid arthritis. Emerging research suggests benefits for brain health and may help prevent Alzheimer's disease. May support cardiovascular health by improving endothelial function. Some evidence for anti-cancer properties in laboratory studies.
Recommended Dosage
Curcumin supplements: 500–2,000 mg daily of curcumin extract (standardized to 95% curcuminoids). Must be taken with piperine (black pepper extract) or in a lipid formulation to improve absorption — curcumin alone has very poor bioavailability (less than 1%). Cooking turmeric: 1–3 grams (about ½–1 teaspoon) of turmeric powder daily. No established RDA.
Food Sources
Turmeric root (fresh or dried), curry powder blends, golden milk (turmeric latte), turmeric tea. Turmeric is a staple in Indian, Southeast Asian, and Middle Eastern cuisines. To enhance absorption from food, combine with black pepper and a source of fat (olive oil, coconut milk).
Side Effects
Generally safe at culinary doses. Supplement doses: May cause digestive upset, nausea, diarrhea, dizziness, and headache. High doses or long-term use: Possible increased risk of kidney stones (curcumin increases urinary oxalate levels). May cause allergic contact dermatitis in sensitive individuals. Can stain skin and clothing yellow.
Interactions
Blood thinners (warfarin, aspirin, clopidogrel) — curcumin has antiplatelet effects, may increase bleeding risk. Diabetes medications — may enhance blood-sugar-lowering effects, causing hypoglycemia. Iron supplements — curcumin may bind iron and reduce absorption. PPIs and antacids — curcumin may increase stomach acid in some people. Chemotherapy drugs — may interfere with certain treatments (consult oncologist).
Warnings
Stop taking curcumin supplements at least 2 weeks before scheduled surgery due to bleeding risk. People with gallbladder disease or gallstones should avoid concentrated curcumin supplements. May worsen gastroesophageal reflux. Not recommended during pregnancy at supplemental doses (culinary amounts are considered safe). Quality varies significantly between products — look for standardized extracts with bioavailability enhancers.
Deficiency Symptoms
Turmeric/curcumin is not an essential nutrient, so there is no clinical 'deficiency.' However, populations with low turmeric intake may miss out on its anti-inflammatory benefits. The standard Western diet is generally much lower in natural anti-inflammatory compounds compared to traditional Asian diets.

Fatty Acids
Omega-3 fatty acids are essential polyunsaturated fats that your body cannot make on its own. The two most important omega-3s found in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They play critical roles in brain function, heart health, and reducing inflammation throughout the body.
