We’ve seen Irwin Naturals products around for years, but it’s only been recently that the company really caught our eye. This long-lasting company in a market that constantly changes is a rarity, so our research team decided to look inside the business.

With details on the products, ingredients, company behind the line, and more, we present the bottom line on Irwin Naturals.

Irwin Naturals can be purchased through their Official Site.

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?

  • Perspectives in Clinical Research – Though commonly found in weight-loss supplements, Caralluma may not be as effective at improving weight loss as some say.
  • Advances in Nutrition – There are also thoughts that green tea can increase fat metabolism. However, more research is needed to replicate the findings accurately.
  • Israel Journal of Medical Sciences – Yohimbe, significantly improved weight loss. Then, you find research in the Journal of Pharmacology that shows the opposite – no effect on weight loss.

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 reviews and one complaint. This leads to the BBB rating of NR (not rated).

Irwin Naturals Customer Testimonials

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 weight management 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. We found one study that showed benefits to both exercise performance and body composition with yohimbine, but it was completed more than 15 years ago. (Research in Sports Medicine)

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

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.

Irwin Naturals Lawsuit

A New York consumer has lodged a class action against a California supplement maker, Irwin Naturals. Irwin Naturals is accused of deceiving customers into believing its supplements are natural when they allegedly contain synthetic ingredients. The lawsuit is pending in New York federal court.

What Users Are Saying

“Helps curb my cravings. 25 lbs gone and still going.”

“I’ve been taking these and there is absolutely no difference in my little “pouch.” I am thin, eat healthy, am active, but as I get older I couldn’t seem to lose my belly. So I gave these pills a chance but there is absolutely no decrease in my belly.”

“I used this product, along with a low carb diet, lots of fruits and veggies, also protein like lean chicken and pork. I didn’t lose any weight.”

We’re not 100% in support of all the supplements or ingredients, but we’d be surprised to find that.
