What is Irwin Naturals?

Irwin Naturals is a supplement company that tackles many health concerns, including weight loss, muscle growth, and hydration. The About Us page is lacking in basic information about the company. It reads more like a focus statement than an About section.

What ingredients does the company use and is science available to support any health benefits?

Company and Better Business Bureau

We are finding blank Better Business Bureau (BBB) pages for companies that have been in business for more than a decade. This is surprising when you consider the number of consumers who’ve ordered products or purchased products.

According to the BBB page, the company is not accredited, and it has received zero complaints and zero reviews. This leads to the BBB rating of NR (not rated).

Irwin Naturals Claims

The claims across all Irwin Naturals products are that they provide support for overall health and wellness. There are no extraordinary claims, and all ingredients are chosen based on solid research. This company is one that offers realistic options without making unrealistic promises.


Common Irwin Naturals Ingredients

Across the 34 supplements, there are some common ingredients that we see come up time and again. These common ingredients are clearly the go-to for Irwin Naturals.

The more common Irwin Naturals ingredients include:

  • Garcinia
  • Caralluma
  • Green Tea (GreenSelect)
  • Forskolin
  • Yohimbe
  • Chromium
  • L-Citrulline
  • Sinetrol
  • Conjugated Linoleic Acid

Details on Ingredients

That’s a long list of ingredients – and that’s only a fraction of the ones used in Irwin Naturals weight-loss supplements. Let’s take a look at each of these ingredients’ details to see if they’re worthy of including in any formula.


Garcinia and the hydroxycitric acid it provides have been studied for years. Researchers are looking to determine if garcinia can improve weight loss. According to NCCIH, there aren’t any studies currently available with positive results.


Research in Complementary Therapies in Medicine found Caralluma was the only plant of those reviewed that affected appetite.

Green Tea

Green tea provides a mixture of EGCG and caffeine. Research published in the International Journal of Obesity concluded that the combination of EGCG and caffeine has a small effect on weight loss and weight maintenance.


Some research has shown that forskolin can increase stored fat release, but the studies were completed decades ago. (See the journal Molecular Pharmacology and the Journal of Lipid Research.)


There’s not a lot of solid research that finds Yohimbe helps with weight loss.

Side Effects

Possible Irwin Naturals Side Effects

Any side effects associated with Irwin Naturals supplements are linked to the ingredients and not the particular formula. Due to the addition of stimulants, the most common side effects may include:

  • Nausea
  • Headache
  • Loss of appetite
  • Excess energy
  • Difficulty falling asleep
  • Shaky feeling

Where to Buy

Irwin Naturals products can be purchased directly from the company or major retailers like Walmart and Amazon. The latter two retailers tend to have the lowest prices.

Pros and Cons

Pros and Cons

There are plenty of good supplements available from Irwin Naturals. We’ve never found a supplement that was really bad from the company.


  • Most of the ingredients are well thought out.
  • The company continues to grow and expand, now into CBD.
  • The prices are lower than much of the competition.
  • Sexual health products are abundant if that’s what you’re looking to buy.
  • Irwin Naturals’ consumer complaints are nearly non-existent.


  • Not all ingredients are worth the time.
  • Some formulas will not contain enough of the active ingredients to be effective – based on amounts used in research.
  • There’s a big push for CBD, but the research into health benefits and proper dosage is lacking.
  • An Irwin Naturals lawsuit filed by Orange County District Attorney for unfair business practices was settled out of court.

6 Irwin Naturals Reviews

  • Sandra

    Hi, can you take together Carb Blocker, Triple Tea Burner and Belly burner?

    • Montana (Editor)

      Hello Sandra. Since these three products contain high amounts of herbal compounds like BioPerine, it may be best to consult with a medical professional to see if this combination is safe for consumption.

  • Made in China? Really?
    Frank (Verified Purchase)

    Are your a products made in China?

    • Montana (Editor)

      Hello Frank. Dietspotlight is not associated with Irwin Naturals. Although our team did find out their company markets and sells their products from California, there is no information on where these supplements are made.

  • No response
    Gail Dawn Schwartz (Verified Purchase)

    I also tried twice to contact them with no response. I too had capsules that leaked, I pulled all the cracked capsules out and wiped the good one off. Next time I went to fill my pill container the good ones were now leaking too.

  • Lynn Girardeau (Verified Purchase)

    I had a coupon for Irwin Naturals CBD that did not work when I made my order, despite it being more than a month before the expiration date. I emailed their customer service office twice and received no response whatsoever. Their flakiness has lost them a customer.
