Why we started with turmeric
Because this is a category where almost everyone sells the same thing, and the number printed on the front of the bottle does not tell you what is inside it.
Look at what is being advertised right now. 95% curcuminoids. 20x absorption. Clinically dosed. Every brand, the same words, often the same sentences in the same order. Meanwhile the most common reason a turmeric supplement does nothing has almost nothing to do with any of that.
Turmeric root is only about 2 to 9% curcuminoids, which are the compounds every clinical trial actually measures. So a capsule containing 1,000mg of turmeric root powder delivers somewhere between 20 and 90mg of the active compound. A capsule containing 1,000mg of a standardised 95% extract delivers roughly 950mg.
Same number on the front. Up to 45 times the difference inside.
Most people who tried turmeric and felt nothing were holding the first bottle. They were not wrong about turmeric. They were reading a number that did not mean what they thought it meant, and nothing on the label told them.
That is the gap we built into. Not a bigger claim. A number you can actually compare.
What is in it
A standardised turmeric extract rather than ground root, with black pepper extract, ginger, bee propolis, MCT oil and vitamin C. The label states 1,000mg of 95% curcuminoid extract per serving.
Curcumin is fat-soluble, so take it with a meal that contains some fat. That instruction is on the bottle because it is useful, not because it sounds clever.
What we will not tell you
We will not tell you this treats or cures anything. It is a dietary supplement, not a medicine. It has not been evaluated by the FDA, and if you are dealing with something diagnosed, that is a conversation for your doctor rather than for a company selling you capsules.
We will not print an absorption multiple. You will see 20x and 2000% across this category. That figure traces back to a single 1998 study that used a 2 gram dose, sampled blood for one hour, compared against a baseline the authors themselves described as undetectable or very low, and was co-authored by the man who holds the patent on the black pepper extract it validates. It has never been independently replicated at that magnitude. More importantly, higher blood levels have not been shown to produce better results. A 2025 network meta-analysis of 17 trials actually ranked conventional preparations slightly above the bioavailability-enhanced ones for pain scores.
So we use black pepper extract because it is standard in this category and because curcumin is genuinely hard to absorb. We do not attach a number to it.
What the research actually says
Meta-analyses of curcuminoids for knee joint comfort show a modest average benefit on pain scores compared with placebo. That is the honest headline.
Here is the rest of it. Every umbrella review published on this literature rates the underlying studies low or critically low quality. One 2025 review of seven systematic reviews found that of 48 outcomes assessed, 37 were rated extremely low quality, and publication bias affected nearly half of them. The most rigorous placebo-controlled trial, published in the Annals of Internal Medicine, found a small pain benefit but measured joint inflammation directly by MRI and found no change at all. There is no completed Cochrane review. The American College of Rheumatology osteoarthritis guideline does not mention turmeric.
The National Center for Complementary and Integrative Health at the NIH puts it this way: the initial evidence is positive, and higher-quality evidence is needed to reach definitive conclusions.
We are telling you this because most of this industry stretches a thin literature into a list of guaranteed benefits. We would rather tell you it is mixed than pretend it is settled.
About the first weeks
We say this before you buy rather than after.
Clinical trials of turmeric for 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. Anyone promising you results in days is not quoting research.
Some people also get stomach effects early on. Nausea, reflux, loose stools. Taking it with food helps. It is the most commonly reported side effect of turmeric supplements and it is the most common reason someone stops in week one.
We mention both because between them they account for most of the people who quit something before it had a chance.
The guarantee, in plain terms
90 days from the day it arrives, not the day you paid.
We set it at 90 deliberately, because the research runs 8 to 12 weeks. A 60-day guarantee on a product that takes twelve weeks to judge is a guarantee that expires before you can use it. If nothing changed, email us and we refund you.
Every condition is on this page. There is nothing you will discover after you have paid.
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 of them.
Talk to your doctor first if you have gallstones or bile duct problems, if you have 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.
Liver problems have been reported very rarely in people taking supplements containing turmeric or curcuminoids. It is rare, and it is real, and you should know about it before you start rather than after.
And if you want something that works this week, this is not it. We would rather say so now than refund you later.
