Irwin Naturals SCORE



Irwin Naturals has some of the best prices and the most robust full spectrum formula out there. We don’t normally recommend buying CBD from a company that offers such sparse information about its products and background; but the lab results are available when you scan the QR code or enter the lot number on the label.

Irwin Naturals carries a short list of CBD format categories, focusing on CBD oils, CBD capsules, and CBD balms. However, it has an astoundingly extensive line of CBD capsules.

Perhaps because Irwin Naturals is a vitamin and supplement company first (CBD is simply an extension of the company’s product line), the CBD capsules come in 18 varieties with special ingredients to boost specific effects.

If you’re okay with not knowing much about your CBD company or your products before you make a purchase, Irwin Naturals may give you some of the best results as far as companies lacking transparency goes.

The website includes very little information about the company; lab results are impossible to find unless you have already purchased a product and have the lot number in-hand; and information about where Irwin Naturals sources its hemp and its extraction methods is vague and buried in the FAQs.

Regardless, this is one of the most robust full spectrum formulas we have seen yet, and the price is fantastic for the quality of the products.

The company claims that it uses organic ingredients and lists all of them on the bottle—but again, this is an area where you just have to trust that this is the case, because you cannot see them before you receive your shipment. The nice thing about this company is that you have 60 days to return your product, even if you have opened and used it.

This is one of the most generous satisfaction guaranteed return policies out of all the companies on our list, and it may make up in some way for the lack of transparency.

  • Robust full spectrum formula
  • Great prices
  • Huge variety of capsules

Background Information

Klee Irwin founded in 1994, and the company has recently been exploding in popularity. It is the leading softgel based supplement company in the US; one of the fastest-growing overall supplement companies in the country; and it is one of only a handful of legacy supplement companies (companies that existed before the supplement craze began in the last decade or so) still on the market today.

Irwin authored the book, Pain Nation, a book about the miraculous benefits of CBD; but most of the time, he is performing quantum gravity research.

That’s right, Klee Irwin is actually a physicist who happens to be so into natural supplements and CBD that he decided to start one of the top supplement brands in the country in his spare time.

Irwin Naturals does not provide us with much information about its hemp sources or its methods. We simply know that the company uses hemp grown in the United States, and that it uses a CO2 extraction method.

The company does third-party lab testing on all of its products, but you need to either have a QR code to scan or a lot number in order to search the results online.

This means you have to make a purchase before looking at the results. Fortunately, the company offers a generous return policy, and you have a full 60 days to confirm your product’s labeling is accurate. 

Shipping and Returns

Once you put your order in for CBD from Irwin Naturals, the company generally processes it within 2 business days.

Shipping is free for all orders over $49, and you can expect to get your shipment within five to seven business days after ordering. Irwin Naturals does not ship internationally at this time, but the company does ship to all 50 states and US territories.

No one likes to wait for their CBD, and we like to get our CBD as soon as possible once we put in an order. We ordered our CBD oil on a Tuesday, and Irwin Naturals processed our order the very next day. Unfortunately, the postal service took a full six days to deliver our package, but we received it within the promised five to seven business days. 

Even if you have opened your CBD products from Irwin Naturals and tried them, you still have a full 60 days to return them for a full refund minus shipping. All you need to do is download the return form, fill it out, and send it to the address listed to receive your refund.

Irwin Naturals’ Products


The CBD oils offered by Irwin Naturals are by no means the star of the show in this line of products. The company offers one kind of CBD oil, in two doses.

It suspends the CBD in cold-pressed hempseed oil to maximize your dose of fatty acids as well, and the flavors are said to be more mellow due to some additives for the flavored option that cut through the bitterness naturally occurring in full spectrum products.

CBD Oils ($19.99 – $42.99) – You can find CBD oils from Irwin Naturals in two concentrations. In the 250mg concentration, you have more flavors to choose from: lemon, peppermint, mint chocolate and tangerine. In the 1000mg concentration, there is only peppermint and unflavored available. 

CBD Capsules

This is where Irwin Naturals really stands out, and you can tell that these CBD capsules are made by the leading softgel producers in the country.

We are only going to cover a sample of the extensive selection of CBD capsules here, but there are 18 different kinds to choose from on the website. These are some of the best prices you will find on the internet for CBD capsules.

CBD Softgels ($26.99 – $69.99) – This is the basic CBD softgel. It is just CBD, flaxseed oil, MCT oil, and Irwin Naturals’ special Bioperine complex, which is supposed to enhance the bioavailability, absorption, and potency of essential nutrients. You can choose between 10mg, 15mg, 30mg, and 50mg of CBD per capsule for ultimate dosing flexibility.

CBD +Power to Sleep ($22.99) – These capsules are your standard CBD plus melatonin capsules. They also include a dose of L-theanine to help balance out your sleep cycle. Bottles contain 60 capsules, each with 7.5mg of CBD.

CBD + Brain Awake ($29.99) – The standard CBd formula, these 10mg CBD capsules also contain Irwin Naturals’ special formula to help you stay at your cognitive peak all day long. Ginkgo extract, B vitamins, and the Alphawave formula will keep you alert and ready to go.

CBD + Probiotic ($34.99) – Studies indicate that CBD is good for your digestive system, and Irwin Naturals has made it even better with its probiotic formula. Made with special ingredients like Bioprene to help improve and maintain your gut health as well as your immune system.

CBD Topicals

Just as with the CBD oil, Irwin Naturals has made the obligatory CBD balm to round out its product line. This balm is super basic, but it will certainly get the job done. You can choose between a variety of concentrations; and the balm is formulated to go on smooth and absorb quickly for a soft, non-greasy feel.

CBD Balm ($34.99 – $54.99) – This balm has a base infused with aloe and sunflower seed oil, and it is scented with lemongrass and blue tansy. The two-ounce bottles contain your choice of 250mg, 500mg, and 1000mg of CBD. 

Lab Results

We sent a sample of Irwin Naturals’ full spectrum CBD oil to a third party lab for testing, so we could get an unbiased picture of what is actually in the bottle.

This helps us give you a better review for a more informed decision. We were very happy with Irwin Naturals profile, except that the amount of CBD labeled was off by 21 percent.

Typically, we can accept a discrepancy of up to ten percent. We are going to cut Irwin Naturals some slack, though, because at least there is 21 percent more CBD, rather than 21 percent less CBD than labeled.

Additionally, this is one of the most robust full spectrum formulas we have come across, with all the minor actives on our list and then some.

We generally like to see a stronger concentration of some of these cannabinoids, like CBG and CBN; but the fact that the formula covers all of them at least a little, makes us pretty confident that you will get an excellent entourage effect from this oil.

Website Experience

The Irwin Naturals website is not entirely dedicated to CBD products, so it is surprisingly organized considering this fact. You can find the company’s entire product line, as well as all of the other labels the company carries.

There is not a whole lot of information about the company itself, CBD, or its sourcing and extraction methods, so not a whole lot of education. Just a lot of products.

You can search for items on the search bar, and you can also take a quiz to find the right product for you. Though the answers are always pretty general and seem like they may be the same no matter how you answer the questions.

Customer Service

We tried to contact Irwin Naturals through both their contact form and customer support email, but never received a response back. Combined with their questionable transparency, this is not a brand you’re likely to receive many answers or much additional information from.

Your mileage with Irwin Naturals will have to depend on how much you trust that they’ll maintain a high level of quality with their products.

Final Verdict

The Irwin Naturals website leaves a lot of questions unanswered, and the lack of access to lab reports before you make a purchase makes us question the company’s transparency in a major way.

However, this company has some of the best prices and the most robust full spectrum formula out there. We don’t normally recommend buying CBD from a company that offers such sparse information about its products and background; but the lab results are available when you scan the QR code or enter the lot number on the label.

Our independent lab results showed a 21 percent discrepancy between the amount of CBD on the label and the amount in the bottle. However, it was 21 percent over, not 21 percent under. We can always feel a little more forgiving when we get bonus CBD.

If you’re into health supplements, you’ll feel like a kid in a candy shop with all the variations of CBD capsules available from Irwin Naturals, and there is bound to be something that piques your interest.

The best part of ordering from Irwin Naturals is that the company offers a 60-day satisfaction guarantee on its CBD products. You can send your items back for a full refund even if you have opened and used them. This allows you to try the products virtually risk-free minus postage.

With nothing to lose, great prices, a robust full spectrum formula, the widest selection of CBD capsules we have seen, and the potential for finding your favorite CBD company yet, we recommend giving Irwin Naturals a shot today!
