18 Best Supplement Affiliate Programs To Earn Extra Cash

The health and wellness industry has been steadily growing over the past several years. With the high costs of healthcare, people are becoming more aware of the need to take care of their health, to prevent sickness before it strikes. Estimates put the global health and wellness industry at a little under 4.5 trillion dollars in 2019, forecasted to reach six trillion dollars by 2025.

Within this larger realm of health and wellness supplements are a niche market that has also seen an uptick in usage. It’s no surprise then, that affiliate marketing programs for supplements abound online. 

Best Supplement Affiliate Programs To Earn Extra Cash:

What Is Affiliate Marketing?

Affiliate marketing is a type of performance-based marketing strategy where third-party partners—called affiliates—promote and advertise products on their own websites or social media accounts. Each successful purchase using these links grants the affiliate a commission from the company. It’s a relatively easy way for influencers to earn additional income while promoting a healthy lifestyle and fitness. In general, affiliate marketing is a passive way to make money online.

We’ve rounded up 18 of the best supplement affiliate programs you should consider joining to earn some extra cash.

1. The Vitamin Shoppe

The Vitamin Shoppe

When it comes to affiliate marketing, brand reputation is key. You are more likely to sell products if people know and trust the company you are promoting. The Vitamin Shoppe is one of the biggest and most reputable supplement companies today, making it a good candidate for affiliate marketing.

The Vitamin Shoppe has over 730 retail shops all over the US, plus its online store. It offers a wide array of organic and natural health products—over 25,000 products from 400 brands, according to its website. Its line of supplements ranges from daily vitamins to special bodybuilding supplements, with varied products targeting different market segments. 

Commission Rate: Starts at 1%, but affiliates can earn up to 10% with extra exposure

Cookie Duration: 7 days

2. Seed

Supplement Affiliate Programs Seed

For those who are into probiotics, Seed’s affiliate marketing program is a good choice. Seed’s chief scientist, Dr. Gregor Reid, has vast experience in probiotic research. In fact, in 2001, he was the chair of the UN and World Health Organization expert panel that did research on and officially defined the term “probiotic.” 

Seed prides itself on its focus on science and research-based products, ensuring that its supplements are based on data. Aside from digestive health, its products are also geared for dermatological and cardiovascular health.

Commission Rate: 25% base rate

Cookie Duration: 30 days

3. Persona Nutrition

Persona Nutrition Supplement Affiliate Program

Persona is a subscription-based vitamin service that offers personalized vitamin packs tailored to your needs. To apply for a subscription, you need to fill out a quick online assessment to determine your vitamin needs. Afterward, you’ll receive a nutritionist-backed recommendation for a vitamin pack suited to your lifestyle and diet.

Its affiliate marketing program operates on a last-click attribution model, meaning affiliates will only be credited for a successful sale if theirs was the last link that the customer clicked on before buying.

Commission Rate: 25%

Cookie Duration: 30 days

4. Amazon Associates

Amazon Associates affiliate marketing program

E-commerce retail giant Amazon’s affiliate marketing program, Amazon Associates, caters to every possible niche market you can think of—including supplements.

A perk of being a part of Amazon Associates is the dizzyingly large number of products you can promote and receive commission for. It’s no secret that Amazon is at the top of many lists as one of the biggest online marketplaces. If a customer clicks on your affiliate link and purchases a lot of stuff on Amazon after that, you can still earn commission from everything they bought using your link.

The downside of Amazon’s affiliate program is the low base commission rate and its super short cookie duration time, perhaps the shortest of any affiliate program.

Commission Rate: 1% base, can go up to 10% 

Cookie Duration: 24 hours

5. New Vitality

New Vitality

New Vitality’s products are mainly targeted at men, but they also have general health and women’s health supplements. This niche market is perfect for male influencers and content creators whose followers are also mostly men. With its philosophy of helping people “live longer and look younger,” New Vitality gives its customers a chance for a fit and healthy lifestyle, all while looking their best. 

The company’s affiliate program includes options for large volume sales, so if you are looking for bulk sales, this program might be suited for you.

Commission Rate: 10%

Cookie Duration: 15 days

6. MarketHealth


A leading health and beauty company with a global reach, MarketHealth is a good option for potential affiliates. With more than 200 products geared toward the health-conscious in 100 countries and counting, affiliates may just find themselves with a global audience to target.

MarketHealth’s website enumerates many different benefits of applying to its affiliate program, such as high commission rates with special commissions for sales over 20, high conversions, and exclusive offers. It can even provide custom offers for experienced affiliates who can target your specific audience.

Commission Rate: 50%, up to 60% for “super affiliates” who get more than 20 sales a day

Cookie Duration: 30 days

7. Stack Labs

Stack Labs specializes in supplements for bodybuilding. Its products are produced with three goals in mind: bulking (developing muscle mass and strength), cutting (lean muscle), and burning (fat loss). It offers good deals, such as getting every third item for free. 

Its affiliate program is very attractive, with a high commission rate and cookies with no expiration. The disadvantage is that compared to other brands, Stack Labs is relatively new to the niche market of bodybuilders. It might be more difficult to market to this specific audience, with more established and recognized brands available.

Commission Rate: 45%

Cookie Duration: No expiration

8. Life Extension

Life Extension

Life Extension has been in the business of health and wellness for more than forty years. Its history goes as far back as 1981, when the company recommended B-complex vitamins to lower the risk of heart disease, stroke, and dementia, as well as the hormone DHEA to slow signs of aging.

Aside from developing products for health and wellness, Life Extension also publishes its own magazine. It’s considered one of the biggest authorities in the vitamins and supplements industry, with 98% of its customers saying they will recommend Life Extension to their peers.

Commission Rate: 4% base, with higher rates for higher sales (up to 12% for sales of $10,000 or more)

Cookie Duration: 120 days

9. Ritual

“Simple, clean, and backed by science.”

This is the philosophy of Ritual, a vitamin supplement company founded by CEO Katerina Schneider. While pregnant, she wanted prenatal vitamins without dubious ingredients but had a hard time looking for a good brand that she can trust. She founded Ritual with the belief that people needed supplements that could deliver much-needed nutrients without added harmful ingredients. Since then, Ritual has developed supplements mainly targeted at women. It uses research-backed ingredients whose supply chains are transparent and traceable. It’s also non-GMO and vegan.

Aside from its promise of clean ingredients, its affiliate program is also top-notch, offering one of the highest commissions in the industry.

Commission Rate: 75%

Cookie Duration: 60 days

10. Rootine

Rootine customized supplements

Similar to Persona, Rootine offers customized supplements. However, its tests are much more in-depth and include even your genes and biomarkers to determine the best possible combination of vitamins and micronutrients for you. Aside from an online lifestyle quiz, it also uses a test you can do at home to study variations in your genes and blood nutrient levels. This laser focus on precision nutrition ensures that you only get what you need according to your vitamin deficiencies.

Following the initial tests to determine the right formula, customers also track their performance and changes in their body, health, and lifestyle through a customized dashboard. 

Commission Rate: $75 flat rate, with bonus commissions of up to $4,000 for reaching specific sales targets

Cookie Duration: 60 days

11. Performance Lab

Performance Lab offers two main product categories: its CORE range, which includes vitamins and supplements designed for daily activities to enhance long-term health, and its SPORT range, developed for people who need muscle growth, strength, endurance, and other athletic activities.

Affiliates will be able to select a niche market that is best suited to their existing audience. The company has also developed vegan supplements—the first vegan protein powder and vegan softgels—to ensure that no niche market is left untapped. Performance Lab has high reorder rates as well as an attractive EPC rate, currently set at $10.

Commission Rate: 30%-50%

With a belief in what it calls “Total Human Optimization,” Onnit delivers supplements to help people reach their optimal levels in their body, mind, and spirit.

Aside from supplements, the company also sells fitness gear and apparel, so affiliates have more products to promote and earn commissions from. Onnit has also secured endorsements from athletes and big-time personalities, so it has also gained a lot of brand recognition. However, its affiliate program will only approve influencers who have more than 5,000 followers.

Commission Rate: 15%, with a trial sign-up commission at $10

Cookie Duration: 45 days

13. GNC Supplements

When it comes to supplements, GNC stands out as one of the most recognized brands around the world. The company has been developing and producing different supplements that cater to a broad market since 1935. From vitamins to weight management supplements and even beauty and skin care, GNC has products for almost any health and fitness goal.

As with other big and established companies on our list, its commission rate is somewhat on the small side, and its cookie life is short. But because of its brand recognition and reputation, affiliates are more likely to earn from bigger sales.

Commission Rate: 5%

Cookie Duration: 7 days

14. EZC Pak

EZC Pak is known for its award-winning immune support supplements. Sold in 5-day packs, this supplement is composed of echinacea, zinc, and vitamin C—hence the “EZC” in its name. It was formulated by California-based physician Dr. Sarath Malepati, who noticed a troubling trend in his patients who requested antibiotics for viral infections or infections that do not need them. This can lead to drug resistance, an increasingly problematic threat to public health.

EZC Pak aims to strengthen people’s immune system, preventing sniffles or sore throats from progressing to full-blown sickness, which might lead people to seek out antibiotics. It’s an excellent niche market for affiliate marketers, especially with COVID-19 making everyone more responsive to immune support supplements.

Commission Rate: 25%, plus 5% for referring more affiliates

Cookie Duration: 1 year (365 days)

15. FanFuel

An affiliate marketing network, FanFuel aims to reshape the industry by cutting out the middleman and providing higher commissions and faster payouts.

FanFuel’s products include supplements for weight loss, bodybuilding and fitness, beauty, and even sexual health. Partners can even reach out to the company if they have a product that they would like to promote with FanFuel.

Bodybuilders can also look toward A1 Supplements for their vitamin and nutrient needs. A1 Supplements has been a fixture in gyms around Tennessee, Georgia, and Kentucky in the US since the late ‘90s.

A1 Supplements also sells lifestyle and herbal supplements for a well-rounded catalog of products that affiliates can promote. It operates its affiliate marketing program through two networks: CJ Affiliates and ShareASale.

Frequently Asked Questions

What are cookies? Why are they important in affiliate marketing programs?

Cookies are files that store tracking data. When you visit a website and you give it permission to use cookies, it can track your activity within the website. While this can raise privacy issues, cookies can be helpful for both online shoppers and retailers. For example, cookies allow a website to keep track of the things you frequently buy from the website, so it can suggest the same items or similar items each time you visit. It also remembers things on your cart, so it doesn’t reset back to zero when you need to check out at a different time.

How are cookies used in affiliate programs? Cookies allow the company to determine which affiliate link a particular purchase came from. Because these cookies store your data, the website can track what link you clicked before making a purchase, so the commission goes to the right affiliate.

What is cookie duration?

Cookie duration or cookie life, in simple terms, is how long an affiliate link can generate commissions for the affiliate. If the cookie duration for an affiliate program is 30 days, then all purchases made using that link within that timeframe earns the affiliate a commission. Once the cookie duration lapses, it is no longer eligible. Thus, the longer the cookie duration, the more chances an affiliate has of earning a commission from their link.

What do I need to know before signing up for a supplement affiliate program?

When researching different affiliate programs, you first need to find out the types of products that they have available. It’s better if you actually use their products so that your posts will be based on experience and would look and sound more natural. This can be significant in the supplements industry—taking the supplements can produce good physical changes, and your followers will be able to see the results in your posts. It’s one way of becoming an effective brand advocate and affiliate marketer. Believe in the product, and it’s easier to persuade others to believe in it, too.

Secondly, ask about their commission rates. Some programs offer a fixed rate so that no matter how much traffic and sales you drive to their website, your commission remains the same. Others offer additional benefits, depending on the product you sell, the amount, or even referrals for other affiliates. Some affiliate programs offer a small base commission rate—as low as 1%—but with an opportunity to increase depending on performance. Some can even go as high as 50% commission per purchase.

Finally, find out their cookie duration. Like commission rates, cookie durations vary widely among the affiliate programs. You should take into account how quickly your followers respond to your posts as well as the conversion rate of the company to determine the cookie duration you are comfortable with.

How much can I earn from a supplement affiliate program?

It depends on a number of factors. A good balance should be struck between the products or brand, the commission rate, and the cookie duration. On the affiliate’s part, you should consider your target market, follower count, and conversion rate.

For most people, doing affiliate marketing provides them with extra cash, but it may not be their main source of income. Because sales may be unpredictable, it’s hard to determine how much you can earn per month. This is why you should do some research on commissions, cookie duration, and conversion rates of affiliate programs you are interested in joining.
