Concentrated Curcumin + Active Support 120 Tablets

Curcumin is the most-asked-about active in our herbal range, so here is the same triage our naturopaths run at the counter. What it suits, what needs a conversation first, and what rules it out.

A good fit if

• You are an adult with no gallbladder, bile duct or liver history and you take no prescription medicines
• You want an isolated, measurable curcuminoid dose rather than a whole-root turmeric preparation
• You are prepared to choose on delivery system rather than on milligrams, which is the decision that actually changes absorption
• You have found plain high-dose extract disappointing and want to understand the formulation options before spending more
• You are comfortable reading the label, including the mandatory liver warning statement every oral curcumin medicine carries

Check with us first if

• Taking anticoagulant or antiplatelet medicines such as warfarin, apixaban, clopidogrel or aspirin. Curcumin inhibits platelet aggregation in laboratory work, and both preclinical studies and a case report suggest an increased bleeding risk. Enhanced-absorption forms raise systemic exposure, which raises the stakes rather than lowering them.
• Surgery, a dental extraction or any procedure coming up. Raise the bleeding question with the surgeon or dentist well beforehand.
• Taking any medicine with a narrow safety margin. Curcumin inhibits CYP3A4, CYP1A2 and CYP2D6, and downregulates intestinal P-glycoprotein, which can raise blood levels of other drugs. CYP3A4 alone handles a large share of prescription medicines.
• Undergoing chemotherapy, or taking tamoxifen or tacrolimus. Interactions are reported, including acute nephrotoxicity in a transplant patient after tacrolimus pretreatment. Decide this with your oncology or transplant team.
• History of kidney stones, or a family history of them. Turmeric-derived products contain oxalate and specialist guidance is to check with your doctor first.
• Low iron or taking iron supplements. Iron-deficiency anaemia has been reported in case reports with turmeric and curcumin products.
• Aged 2 to 17. Australian regulation caps the daily curcumin content of a medicine by age band, so this is a label question rather than a guess, and European regulators say use under 18 is not established.
• Reflux, nausea or loose stools come on easily. Diarrhoea, headache, rash and yellow stool have all been reported, and nausea was more common on the micellar formulation in the absorption study.
• Choosing a high-strength or enhanced-absorption product specifically. These are the formulations that deliver the most curcumin systemically, so every interaction above applies more forcefully.
• Buying from an overseas website. Those products are not TGA-regulated for quality and safety, and are not bound by the Australian paediatric limits.

• Unformulated curcumin extract (95% curcuminoids). Best known for: The cheapest way to buy curcuminoids by the milligram, and the reference point every other form is measured against. Absorption: Poor. Barely water-soluble and heavily conjugated in the gut wall and liver; serum curcumin after gram-scale doses is often undetectable or very low. Typical use: High-milligram capsules. The number on the label is curcuminoid content, not what reaches your blood.
• Curcumin with piperine (black pepper alkaloid). Best known for: The cheapest genuine upgrade, and the pairing traditional cooking arrived at independently. Absorption: The original 1998 human study gave 2 g curcumin with 20 mg piperine and reported a 2,000% increase; an independent head-to-head crossover found piperine combinations no better than a standard mixture. Typical use: Widely used in Australian tablets. Piperine works by slowing the enzymes that clear curcumin, which is also why it raises the interaction stakes.
• Phytosome / lecithin complex (Meriva). Best known for: Binding curcuminoids to phospholipids so they travel as a fat-friendly complex, allowing much smaller doses. Absorption: 29-fold higher total curcuminoid absorption than the matching unformulated mixture in the manufacturer-linked study; 7.9-fold in an independent four-arm crossover. It also shifts the plasma profile toward demethoxycurcumin rather than curcumin. Typical use: Low-milligram tablets. A few hundred milligrams, not grams. Present in the Australian range under the Meriva name.
• Micellar and liquid solubilisate. Best known for: The largest absorption increase measured in humans, achieved by pre-dissolving curcuminoids into micelles. Absorption: 185-fold higher AUC than native powder across 23 subjects, and markedly sex-dependent: 277-fold in women versus 114-fold in men. Micronised powder alone gave 9-fold. Typical use: Liquids, drops and sports formulas. Nausea was reported more often on the micellar arm than the others.
• Curcuminoids with turmeric essential oil (BCM-95 / Curcugreen). Best known for: Using turmeric's own volatile oils, notably ar-turmerone, instead of added pepper. The piperine-free option. Absorption: Manufacturer-sponsored pilot crossovers report large multiples, but an independent head-to-head found the turmeric-rhizome-with-volatile-oils approach only 1.3-fold above a standard mixture. Treat the branded figure cautiously. Typical use: Common in Australian 'bio-curcumin' products, and the usual choice for people who react badly to piperine.
• Water-dispersible colloidal dispersion (Theracurmin). Best known for: Milling curcumin into colloidal particles that disperse in water rather than needing a fat or a carrier. Absorption: Reported as substantially higher than curcumin powder in small crossover studies by the developer's own group; no independent Australian-relevant head-to-head was verified for this build. Typical use: Very low milligram doses and drink-mixable powders; less common on Australian shelves than phytosome or piperine forms.
• Liposomal curcumin. Best known for: Phospholipid encapsulation delivered as a liquid. The premium end of the category. Absorption: Encapsulation is a recognised strategy in the literature, but published human comparative pharmacokinetics against a phytosome or micellar product are thin. Typical use: Oral liquids, usually dosed by millilitre. Price per milligram of curcuminoid is the highest of any form here.

Reference values. None. Curcumin is a plant compound, not an essential nutrient, so the NHMRC Nutrient Reference Values set no RDI, EAR or Adequate Intake for it. There is no amount you are required to obtain.

Typical supplemental range. The dose depends entirely on the delivery system, which is what makes label comparison so difficult. Unformulated extracts are sold in high milligram amounts, often 500 mg to well over a gram of curcuminoids a day. Phytosome and micellar products are deliberately dosed far lower, in the low hundreds of milligrams, because the whole point of the formulation is to need less. Comparing two products on curcuminoid milligrams alone will mislead you every time; a few hundred milligrams of a phospholipid complex is not a smaller dose than a gram of plain extract in any meaningful sense.

Upper level. No NHMRC Upper Level of Intake exists. Tolerability has been tested well above retail amounts: a dose-escalation trial in 24 adults found single doses up to 12 g were safe, and 8 g a day for three months was reported as well tolerated. Australia does impose regulatory ceilings for children, expressed as milligrams of curcumin per day by age band and quoted verbatim in the Australian status section below, alongside a prohibition on use under two years of age.

Worth knowing. Read the label for the delivery system before you read it for the milligrams. That single habit will do more for your decision than any dose figure. Absorption also differs by sex: in the micellar comparison women absorbed substantially more curcuminoid than men from the same dose, which no label accounts for. Your needs depend on your age, diet and health circumstances. Talk to one of our naturopaths.

Food first, where the diet allows it.

• Ground turmeric, the dried spice: curcuminoids are 2–9% by weight, so a 3 g teaspoon supplies roughly 60–270 mg of curcuminoids, of which about three-quarters is curcumin
• Curry powders and masala blends: turmeric is usually only part of the blend, so the curcuminoid contribution per serve is a fraction of a teaspoon of pure spice
• The practical limit of food as a source: reaching even a few hundred milligrams of curcumin from food means eating several grams of spice a day, which is why supplements exist as a separate category

This list is the part of the page we will not shorten. If any of it applies to you, talk to one of our naturopaths or your doctor before starting.
