Nature’s Formulas is a supplement brand that sells a turmeric/curcumin supplement called Curcumin180. The brand describes this supplement as a "revolutionary formula...for maximum clinical strength inflammation support."
But does Curcumin180 contain research-backed ingredients for inflammation support? Does it contain any unhealthy ingredients? Why do we have issues with the brand's marketing practices? And is Curcumin180 better or worse than popular curcumin supplements like Qunol Turmeric?
In this review we’ll answer all of these questions and more, as we analyze the ingredients in Curcumin180 to give our take on whether or not the supplement is likely to be effective for inflammation, and whether or not it's healthy overall.
We'll also share our concerns about the customer testimonials published by the brand, along with their health claims, and compare Curcumin180 to other popular turmeric extract supplements to pick our winners (and losers).
Key takeaways:
- We consider Curcumin180 likely to provide inflammation support
- Brand uses stock images for customer testimonials
- "180x" absorption claim is not supported
- We do not currently recommend Nature's Formulas
Ingredient Analysis
The ingredients in Curcumin180 are shown below:
image source: https://www.naturesformulas.com/
Turmeric root extract is included at a dosage of 335 milligrams (mg).
We consider this to be an effective dose based on a meta-study of turmeric extract in individuals with osteoarthritis. This study analyzed data from 10 clinical trials, and in all trials, turmeric therapy improved pain scores significantly.
The minimum dose used in any of the trials was 200 mg, which is significantly less than the dose in Curcumin180.
Turmeric root powder is a less potent version of the same plant compound, so it may provide additional inflammation support.
BioPerine is an effective ingredient for a turmeric/curcumin supplement, because as we documented in our review of BulkSupplements, this compound is clinically shown to increase turmeric absorption by up to 2,000%.
Boswellia extract is included at a dosage of 180 mg, and a 2020 medical review suggests this ingredient may be effective for pain relief at the dose in Curcumin180.
The inactive ingredients in this supplement (hypromellose, water) should be safe and non-toxic.
Overall, we consider Curcumin180 likely to provide inflammation support, because its core active ingredients appear to be effectively-dosed and backed by clinical research.
Are the Customer Testimonials Fake?
Nature’s Formulas has a Testimonials page on their website featuring supposed user headshots that are found elsewhere on the web:

The testimonial from supposed customer “Steve Alldis,” for example, can be found on a German website linked here.
Another testimonials image on the Nature's Formulas homepage features a woman's face that's found on an Adobe stock image (linked here):

We find this marketing practice to be highly concerning, and we would urge the brand to only use customer testimonial images from real customers.
We consider this marketing practice to be a red flag in regard to brand quality.
Highly Questionable Health Claims
Nature's Formulas makes a number of questionable and uncited health claims about the Curcumin180 supplement.
As shown below, the brand claims (without proof) that the supplement is "180x more effective," presumably compared to other curcumin supplements:

Nature's Formulas claims (without proof) that their supplement is 180x more potent, which is easy to disprove given that there are many other turmeric extract supplements on the market with the same standardization ratio (95% curcuminoids) but a higher dose.
A brand called Qunol currently sells a turmeric supplement with the same standardization ratio, but a much higher turmeric extract dose, as shown below:

The brand claims "180x more absorption" (without proof).
As we documented in the ingredient analysis, BioPerine does improve turmeric absorption by up to 20x, but we haven't come across any medical evidence that Curcumin180 is likely to have 180x more absorption than any other turmeric supplement.
We recommend that consumers be wary of supplements brands making specific health claims without providing any proof.
Highly Questionable Marketing Practices
The Nature's Formulas website suggests that the brand is associated with major research institutions including Mayo Clinic and Cleveland Clinic, as shown below:
image source: https://www.naturesformulas.com/
There is no proof provided of this working agreement, nor have we seen any evidence from these research organizations that they're partnered with Nature's Formulas.
Claiming to "work with" leading research centers if there is no actual working agreement in place would be extremely unfair to consumers.
Later on this same page, the brand states that they base their formulations on research published by major institutions, and if this is the extent of the relationship, we would consider these marketing claims to be highly unfair to consumers and arguably misleading.
As shown below, on the same page the brand has a header advertising "Clinically-Proven Results:"
image source: https://www.naturesformulas.com/
However, no clinically proven results are cited, and we can't find any clinical trials on any supplements sold by Nature's Formulas.
Another strange and confusing aspect of Nature's Formulas' marketing is that the Twitter link in the footer of their website, at the time of updating this article, does not direct to a Twitter handle for Nature's Formulas but rather to an individual named Demetrice Etheridge.
Nature's Formulas vs. Popular Turmeric Brands
Here's how Nature's Formulas Curcumin180 compares to other popular turmeric/curcumin supplements, in our opinion:
Thorne Curcumin Phytosome
Phytosomal curcumin may have superior absorption and additional benefits according to clinical research, but it's too early to say for certain.
We consider Thorne to be a much more reputable brand than Nature's Formulas, so we consider this supplement to be the safer choice.
Winner: Thorne Curcumin Phytosome
Qunol Turmeric
This brand uses an effective turmeric extract dose and no unhealthy additives, as we documented in our Qunol Turmeric review article.
We consider Qunol Turmeric to be the superior option from a brand quality standpoint.
Winner: Qunol Turmeric
BulkSupplements Turmeric Extract
BulkSupplements has performed poorly in independent testing of off-the-shelf supplements for purity and potency.
While we don't currently recommend either brand, we consider Nature's Formulas to be a better option than BulkSupplements, because we haven't seen any studies showing Nature's Formulas' products to fail testing.
Winner: Nature's Formulas
Our Clean Curcumin Pick
MBG Turmeric Potency+ is our top curcumin supplement pick.
This supplement contains turmeric extract, but it also contains ginger root extract, which was shown to have anti-inflammatory effects in a medical review published in the Nutrients journal.
