FAQ

I have tried turmeric before and it did nothing. Why would this be different?

Because there is a good chance you were never taking a research-level dose, and the bottle would not have told you.

Turmeric root is only about 2 to 9% curcuminoids, the compounds clinical trials actually measure. So 1,000mg of turmeric root powder gives you roughly 20 to 90mg of the active compound. 1,000mg of a standardised 95% extract gives you about 950mg. The number on the front of the bottle is identical either way.

Go and find the bottle you gave up on. Look for a line that says curcuminoids. On most bottles there is not one.

What does 95% curcuminoids actually mean?

It means the extract has been standardised so that 95% of its mass is curcuminoids. It does not mean 95% curcumin.

Curcuminoids are a family of three compounds: curcumin, demethoxycurcumin and bisdemethoxycurcumin. Curcumin is roughly three quarters of the total. Nearly every brand in this category prints 95% without ever explaining that, and it is worth knowing what you are reading.

How long before I notice anything?

Clinical trials of turmeric and curcumin for knee joint comfort have typically run 8 to 12 weeks, and the placebo-controlled trials that reported a benefit measured it at 8 to 12 weeks. We have found no trial showing separation from placebo earlier than about four weeks.

So the honest answer is give it two to three months. Anyone advertising results in days or in one week is not quoting research.

What about 20x or 2000% absorption?

We do not claim a multiple, and here is why.

That figure comes from one study published in 1998. It used a 2 gram dose, which is four times a typical supplement serving. It sampled blood for one hour. The comparison baseline was described by the authors themselves as either undetectable or very low, so it is a very large percentage of a very small number. And it was co-authored by the founder of the company that holds the patent on the black pepper extract the study validates. It has never been independently replicated at that magnitude.

There is a bigger problem. Higher blood levels have not been shown to produce better outcomes. A 2025 network meta-analysis of 17 trials ranked conventional curcumin preparations slightly above bioavailability-enhanced ones on pain scores.

Curcumin is genuinely poorly absorbed on its own. Black pepper extract is standard in this category and it is in ours. We just will not put a number on it that the evidence does not support.

How should I take it?

As directed on the label, with a meal that contains some fat. Curcumin is fat-soluble, so food genuinely helps.

Will it upset my stomach?

It can. Gastrointestinal effects are the most commonly reported side effect of turmeric supplements: nausea, reflux, stomach upset, loose stools or constipation. Taking it with food reduces the chance.

If it does not settle, stop taking it and claim the guarantee. We would rather refund you than have you push through it.

Is it safe to take long term?

The NIH National Center for Complementary and Integrative Health states that conventional oral turmeric is likely safe in recommended amounts for up to two or three months, and that highly bioavailable formulations may harm the liver. Use beyond about six months has not been well studied.

Liver problems have been reported very rarely in people taking supplements containing turmeric or curcuminoids. If you plan to take it continuously, talk to your doctor.

Who should not take this?

Talk to your doctor first if you take blood thinners or antiplatelet medicines, diabetes medication, or sulfasalazine. Turmeric has documented interactions with all three.

Talk to your doctor first if you have gallstones or bile duct problems, liver disease, if you are pregnant or breastfeeding, or if you have surgery coming up.

If you are undergoing cancer treatment, current guidance is not to take turmeric or curcumin supplements alongside it.

Will this fix my condition?

We are not going to answer that, and you should be wary of any supplement company that does.

This is a dietary supplement, not a medicine, and it has not been evaluated by the FDA. If you are dealing with a diagnosed condition, take that question to your doctor rather than to a company selling you capsules.

What we will tell you is what the research looked at. Meta-analyses of curcuminoids for knee joint comfort show a modest average benefit on pain scores versus placebo. Every umbrella review of that literature rates the underlying studies low or critically low quality. The most rigorous placebo-controlled trial measured joint inflammation directly by MRI and found no change. There is no completed Cochrane review, and the American College of Rheumatology osteoarthritis guideline does not mention turmeric at all.

That is the honest version. It is also the reason we do not publish the longer list of claims you will see elsewhere.

Are there artificial fillers?

No artificial fillers. The formula is turmeric extract, black pepper extract, ginger, bee propolis, MCT oil and vitamin C.

Worth knowing about this category generally: an analysis published in Food Chemistry found that 22% of turmeric supplements contained undeclared ingredients, most often synthetic curcumin substituted for genuine extract, and 13 brands have been recalled over lead contamination. It is a real problem and it is why the ingredient list matters more than the marketing.

What is the guarantee?

90 days from the day your order arrives, not the day you paid.

We set it at 90 on purpose. The research runs 8 to 12 weeks, so a shorter guarantee would expire before you could fairly judge it. If nothing changed, email us and we refund you. Every condition is on this page and there is nothing that appears only after you have bought.
