What Is Irwin Naturals and Why Does It Keep Coming Up
Irwin Naturals is a Los Angeles-based supplement company that has been around since 1994. They make soft-gel vitamins, herbal blends, and CBD products. The founder, Klee Irwin, built the brand around liquid soft-gel technology — which basically means the nutrients are suspended in liquid oils inside the capsule instead of being pressed into a hard tablet. The idea is faster absorption. Whether you are looking at their stress support formulas, their testosterone boosters, or their CBD line, that soft-gel format is the through-line across almost everything they sell.

Skip to My Match →The company operates out of irwinnaturals.com and sells through major retailers like Walmart, CVS, Whole Foods, and Amazon. They carry over 100 SKUs across categories like brain health, heart health, men’s health, women’s health, digestion, and CBD. That is a wide catalog. Most supplement brands pick a lane. Irwin Naturals picked about twelve of them.
Here is the thing that makes them worth paying attention to: they were one of the first legacy supplement brands to pivot hard into CBD when hemp-derived cannabidiol became federally legal under the 2018 Farm Bill. A lot of companies tested the waters. Irwin Naturals dove in. They acquired a chain of CBD retail stores and started building out a product line that now includes oils, topicals, gummies, and soft-gels with added cannabinoids like CBN and CBG.
The History Behind Irwin Naturals
Klee Irwin started the company in 1994 in Los Angeles. The original focus was on liquid soft-gel supplements. At the time, most supplement companies were selling hard-pressed tablets or basic capsules filled with powder. The soft-gel approach was a differentiator. Irwin Naturals marketed it as a way to improve bioavailability — meaning more of the active ingredient actually gets into your bloodstream instead of passing through your system unused.
For about two decades, the company stayed in that traditional supplement lane. Products like “Power to Sleep PM,” “Stored Fat Belly Burner,” and “Steel Libido” became recognizable names on store shelves. Some of those products have been in continuous production for over 15 years. That kind of shelf longevity is unusual in the supplement world, where brands and formulas rotate constantly.
Then came 2019. Irwin Naturals acquired the CBD retail chain formerly known as Retail By Moxie, rebranding those locations under the Irwin Naturals banner. The acquisition gave them physical storefronts dedicated to cannabinoid products, which was a bold move when most CBD companies were operating purely online. At peak, they operated around 25 retail locations across states like Florida, Texas, and Arizona.
The CBD Pivot and What It Meant
The move into CBD was not just adding a few products to the website. Irwin Naturals restructured parts of their business around it. They formed a subsidiary called Irwin Naturals CBD and started developing formulas that combined their existing supplement expertise with hemp-derived cannabinoids. For example, their “CBD + Power to Sleep” product merged melatonin and herbal sleep aids with CBD oil — taking an existing bestseller and layering cannabinoids on top.
That approach set them apart from CBD companies like Irwin Naturals that were entering the market with CBD-only products. Most new CBD brands at that time had no background in supplements. They were starting from zero on formulation, manufacturing relationships, and retail distribution. Irwin Naturals already had all three.
By 2022, the company reported that CBD products represented a growing share of their revenue. They also expanded into minor cannabinoids. Products with CBN (cannabinol, often marketed for sleep) and CBG (cannabigerol, marketed for focus and inflammation) started showing up in their lineup. This was ahead of the curve. Many CBD brands did not start offering minor cannabinoid products until 2023 or later.
What Products Does Irwin Naturals Actually Sell
The product catalog at irwinnaturals.com breaks down into two main categories: traditional supplements and CBD products. Here is a closer look at both.
Traditional Supplements
These are the soft-gel products that built the brand. Key lines include:
Power to Sleep PM — A melatonin and herbal blend with L-theanine, GABA, and ashwagandha. It has been one of their top sellers for years. The soft-gel format means it hits faster than a tablet, which matters for a sleep product. You take it 30 minutes before bed.
Steel Libido and Steel Libido RED — Male enhancement supplements using a blend of horny goat weed, maca, saw palmetto, and L-arginine. These are positioned in the men’s health aisle at retailers and have a loyal repeat customer base.
Stored Fat Belly Burner — A weight management supplement built around green tea extract, garcinia cambogia, and chromium. It is one of the more commercially visible products in the Irwin Naturals catalog and usually sits in the diet section at stores like Walmart.
Brain Awake — A cognitive support formula with MCT oil, L-theanine, and acetyl L-carnitine. Targeted at people looking for focus without stimulants, though it does contain a small amount of caffeine from green tea.
There are dozens more. Gut health formulas. Inflammation support. Collagen products. Biotin for hair and nails. The catalog is wide. Each product follows the same liquid soft-gel format.
CBD and Cannabinoid Products
The CBD line mirrors much of the traditional supplement structure but adds hemp-derived cannabinoids. Key products include:
CBD + Power to Sleep — Combines 10mg of CBD per soft-gel with melatonin and the same herbal sleep blend from the original formula. This is a good example of how Irwin Naturals layers cannabinoids onto existing formulas rather than selling standalone CBD oil.
CBD + Sunny Mood — Pairs CBD with St. John’s Wort and saffron extract. Targeted at mild mood support. The combination of a traditional herbal approach with CBD is the kind of thing that CBD companies like Irwin Naturals with supplement backgrounds can do more credibly than a pure CBD startup.
CBD Soft-Gels (standalone) — Available in 15mg and 30mg per soft-gel options. Broad-spectrum and full-spectrum versions exist depending on the product. Third-party lab tested, with COAs (certificates of analysis) available on irwinnaturals.com.
CBD Topicals — Balms and creams for localized relief. These typically combine CBD with menthol, camphor, or arnica for a cooling or warming effect on sore muscles and joints.

This is where things get practical. Supplement quality varies wildly across the industry. The FDA does not approve dietary supplements before they go to market. Companies are responsible for their own testing and compliance. So the question with any supplement brand is: what are they actually doing to verify their products?
Irwin Naturals states that their products are manufactured in GMP-certified facilities. GMP stands for Good Manufacturing Practice. It is a set of standards enforced by the FDA for how supplements should be produced, tested, and labeled. GMP certification means the facility has been audited and meets baseline requirements for cleanliness, ingredient verification, and label accuracy.
For their CBD products specifically, Irwin Naturals provides third-party lab results. These COAs test for cannabinoid potency (making sure the product actually contains the amount of CBD listed on the label), pesticides, heavy metals, residual solvents, and microbial contaminants. You can usually find these on the product pages at irwinnaturals.com or by scanning a QR code on the packaging.
That said, Irwin Naturals does not appear to carry a USP Verified mark or NSF Certified for Sport designation on their traditional supplements. Those are optional, higher-tier certifications that some brands pursue. USP verification, for example, involves independent testing of every batch. It is expensive and time-consuming. Many mid-market supplement brands skip it. That does not mean the products are bad. It means they have not gone through that additional layer of third-party verification beyond what GMP requires.
What About the Ingredient Sourcing
Irwin Naturals sources hemp for their CBD products from U.S.-grown industrial hemp. The 2018 Farm Bill requires that hemp-derived CBD contain less than 0.3% THC by dry weight. Irwin Naturals states compliance with this threshold across their CBD line.
For their traditional supplement ingredients — things like ashwagandha, turmeric, saw palmetto — the company uses a mix of standardized extracts and whole-plant materials. Standardized extracts are important because they guarantee a minimum concentration of the active compound. For example, a standardized ashwagandha extract might guarantee 5% withanolides, which is the compound believed to provide the adaptogenic effect. Without standardization, the amount of active compound can vary from batch to batch.
Who Actually Buys Irwin Naturals Products
The customer base skews toward adults aged 30 to 60 who shop for supplements in physical retail stores. That is a key distinction. A lot of newer supplement brands are DTC (direct-to-consumer) only, meaning they sell exclusively through their own website or Amazon. Irwin Naturals has deep retail distribution. You can walk into a CVS or Walmart and pick a bottle off the shelf. That accessibility matters for a demographic that still prefers to see and hold a product before buying it.
The price point lands in the mid-range. A bottle of Power to Sleep PM with 60 soft-gels typically runs between $14 and $20 depending on the retailer. CBD products are priced higher — a 30-count of CBD soft-gels might be $25 to $40. These are not budget-bin prices, but they are well below premium CBD brands that charge $60 to $100 for similar quantities.
There is also a segment of customers who come to Irwin Naturals specifically through the CBD retail stores. These are walk-in shoppers who may not have known the brand before but encountered the storefront in a strip mall or shopping center. The in-person experience lets staff explain products, recommend doses, and build trust in a way that an Amazon listing cannot.
Common Mistakes People Make With Irwin Naturals Products
A few things come up repeatedly in customer reviews and forums.
Taking the Wrong Dose
Some Irwin Naturals products have a serving size of two or three soft-gels. People sometimes take one and wonder why they do not feel anything. Always check the label. The “Supplement Facts” panel on the back of every bottle lists the serving size. If it says “Serving Size: 3 Liquid Soft-Gels,” that means three. Not one.
Expecting Immediate Results From Herbal Formulas
Sleep products can work the same night. But something like Steel Libido or Brain Awake may take days or weeks of consistent use before any noticeable effect. Herbal supplements often build up in your system over time. Taking it once and declaring it useless is not a fair test. Most herbal formulations need at least two to four weeks of daily use.
Confusing CBD Strength
This happens across the entire CBD industry, not just with Irwin Naturals. A bottle might say “300mg CBD” on the front. That is the total CBD in the entire bottle. If there are 30 soft-gels inside, each one contains 10mg. People sometimes think each soft-gel contains 300mg, which would be an enormous dose. Read the per-serving amount, not the total amount.
Storing Products Incorrectly
Soft-gels are more sensitive to heat than tablets. If you leave a bottle of Irwin Naturals soft-gels in a hot car or next to a window, they can melt together and degrade. Store them in a cool, dry place. The bathroom cabinet is not ideal either — humidity from showers can affect gel integrity over time.
How Irwin Naturals Compares to Other Brands
There are hundreds of supplement brands on the market. Comparing Irwin Naturals to a few key competitors helps put things in context.
Irwin Naturals vs. Nature Made
Nature Made is one of the most recognized supplement brands in the U.S. and carries USP Verified marks on many products. That gives Nature Made an edge in third-party verification. However, Nature Made focuses primarily on single-ingredient vitamins and minerals — Vitamin D, fish oil, magnesium. Irwin Naturals tends toward multi-ingredient herbal blends. They serve different needs. If you want a straightforward Vitamin D supplement, Nature Made is a solid pick. If you want a multi-herb sleep formula in a soft-gel, Irwin Naturals is more likely to have what you need.
Irwin Naturals vs. Charlotte’s Web
Charlotte’s Web is one of the most established CBD brands in the country. They grow their own hemp and have a strong reputation for quality and transparency. Their products tend to be priced higher than Irwin Naturals CBD offerings. The main difference is focus — Charlotte’s Web is a CBD company first. Irwin Naturals is a supplement company that expanded into CBD. CBD companies like Irwin Naturals that come from a supplement background often have more complex formulas because they blend cannabinoids with traditional herbs and nutrients. Charlotte’s Web keeps it simpler, often offering standalone CBD or CBD with one or two added ingredients.
Irwin Naturals vs. Garden of Life
Garden of Life positions itself in the organic and whole-food supplement space. Their products are often USDA Organic certified and Non-GMO Project Verified. Irwin Naturals does not emphasize organic sourcing to the same degree. Garden of Life also uses capsules and powders more than soft-gels. If organic certification matters to you, Garden of Life has a clear advantage. If you prioritize the liquid soft-gel format and broader product range including CBD, Irwin Naturals has more options.
The Retail Store Experience
One thing that makes Irwin Naturals unusual among CBD companies like Irwin Naturals is the brick-and-mortar retail presence. The company acquired and rebranded a chain of CBD-focused stores starting in 2019. These stores are typically small-format — around 800 to 1,200 square feet — and located in suburban shopping centers.
Inside, you find the full range of Irwin Naturals CBD products plus some traditional supplements. Staff are trained to explain the differences between CBD, CBN, and CBG. They can walk you through dosing, product formats, and what to expect. For someone who has never tried CBD before, this in-person guidance can make the difference between a good first experience and a confusing one.
The store count has fluctuated. After the initial acquisition, they opened aggressively. Some locations were later consolidated. As of early 2026, the company maintains a smaller but more focused retail footprint. The remaining stores tend to be in markets with high foot traffic and favorable state regulations around hemp-derived products.
What Happens If You Buy From irwinnaturals.com
Shopping directly from irwinnaturals.com gives you access to the full product catalog, which is larger than what any single retailer carries. The website also offers bundles, subscribe-and-save discounts, and seasonal promotions that you will not find at Walmart or CVS.
Shipping is standard — usually arrives within five to seven business days for domestic orders. The site has a returns policy, though the specifics (time window, condition requirements) can vary. Check the FAQ section before ordering if that matters to you.
One advantage of buying direct is access to lab results. Each CBD product page on irwinnaturals.com links to or displays the third-party COA for that product. You can verify potency and purity before you buy. Retail stores do not always make this information as accessible.
The website also has a blog and educational section covering topics like how CBD works, dosage guides, and ingredient spotlights. The content is branded — it is marketing material — but it does contain useful baseline information for people new to CBD or to specific supplement ingredients.
Frequently Asked Questions About Irwin Naturals
Is Irwin Naturals FDA approved?
No dietary supplement is FDA approved. The FDA does not approve supplements the way it approves pharmaceutical drugs. Irwin Naturals products are manufactured in GMP-certified facilities, which means they meet the FDA’s manufacturing standards. But the products themselves are not individually reviewed or approved by the FDA before sale. This is true for every supplement brand on the market.
Does Irwin Naturals CBD contain THC?
It depends on the product. Their broad-spectrum CBD products are formulated to contain non-detectable levels of THC. Their full-spectrum products may contain trace amounts of THC — up to the federally legal limit of 0.3%. Check the product label and the third-party lab report for specifics.
Where can I buy Irwin Naturals products?
You can buy them at irwinnaturals.com, Amazon, Walmart, CVS, Whole Foods, and other retail chains. Availability varies by product and location. The full catalog is available on the company website.
Are Irwin Naturals soft-gels better than tablets?
Soft-gels can offer faster absorption because the ingredients are already in liquid form inside the capsule. Tablets need to break down first in your digestive system. Whether that translates to a noticeably better result depends on the specific ingredient and your individual digestive health. For fat-soluble nutrients like Vitamin D or omega-3s, the liquid format can be a meaningful advantage.
How long does it take for Irwin Naturals products to work?
Sleep products like Power to Sleep PM typically take 30 to 60 minutes. CBD soft-gels can take 45 minutes to two hours because they pass through the digestive system. Herbal formulas for mood, energy, or libido often require two to four weeks of daily use before you notice consistent effects.
The CBD Your Body ACTUALLY ABSORBS
Most CBD passes right through you. This one doesn't — 440% better absorption, zero THC, made in the U.S.
See Why People Are SwitchingFinal Thoughts on Irwin Naturals
Irwin Naturals occupies a specific spot in the supplement market. They have been around for over 30 years. They have retail distribution that most brands cannot match. Their liquid soft-gel format is a genuine differentiator. And their move into CBD — with retail stores, minor cannabinoids, and hybrid supplement-CBD formulas — puts them in a category that very few competitors occupy.
They are not the cheapest option. They are not the most premium. They sit in the middle and serve a broad audience that wants accessible, reasonably priced supplements with a format that absorbs well. If you are comparing CBD companies like Irwin Naturals to pure-play CBD startups, the depth of their traditional supplement expertise is hard to match. If you are comparing them to pharmaceutical-grade supplement brands, they fall short on certifications like USP Verified.
The brand does what it does and has done it for three decades. That kind of staying power, in an industry with constant turnover, counts for something. Visit irwinnaturals.com to browse their full product line and check third-party lab results for yourself.
