A-Z Strategies for Selling Supplement Products on Amazon 2025

Picture this: you’ve poured your heart into launching a supplement product on Amazon, dreaming of skyrocketing sales and a loyal customer base. But instead, you’re met with frustration—your listing is buried under competitors, reviews are trickling in at a snail’s pace, and your advertising costs are eating away at your profits. The Amazon marketplace feels like a maze, with high competition, complex algorithms, and the constant pressure to optimize every detail. These are the real pain points supplement sellers face, whether you’re a beginner struggling to get noticed or an experienced seller trying to scale. The issues; low visibility, slow sales growth, and the challenge of building trust—can feel overwhelming.

But there’s hope. With the right strategies, you can navigate these challenges and turn your supplement product into a success story. In this blog, we’ll walk you through a proven playbook for selling supplement products on Amazon, covering everything from optimizing your main image to mastering PPC campaigns. We’ll show you how to boost visibility, earn customer trust, and drive consistent sales, helping you overcome the hurdles and build a thriving business. Let’s embark on this journey to transform your Amazon supplement venture.

1. Listing Optimization for Supplement Products

Listing Optimization is crucial for selling supplement products on Amazon because it directly impacts visibility, trust, and conversion rates. A well-optimized listing with a clear title, informative bullet points, and a compelling main image helps your product stand out in a competitive market. Since supplements are health-related, customers rely heavily on detailed descriptions, verified reviews, and clean visuals to make confident purchase decisions. Proper optimization also ensures better indexing for relevant keywords, increasing your chances of appearing in top search results.

Optimizing Your Main Image

Let’s dive into listing optimization with a focus on the main image. For our product, vitamin D3 drops for infants, launched earlier this year, we carefully designed the main image. The packaging and bottle are prominently displayed, aligning with what most competitors do. When searching for the most common keywords for this product on Amazon, you’ll notice that competitors primarily use their packaging and product bottle in their main images. Some also highlight ingredients or show the dropper alongside the bottle.

Since most sellers stick to showcasing the bottle and packaging, we optimized our main image to follow this trend. However, we’re also working on an alternative main image that includes the ingredients and dropper. In the future, we plan to run A/B tests to determine which version performs better.

Crafting Effective Titles and Bullet Points

Alongside the main image, we’ve optimized the title and bullet points for our vitamin D3 drops. These elements are critical for conveying the product’s value and improving searchability, ensuring potential customers find our listing easily.

Crafting effective titles and bullet points is a data-driven necessity when selling supplements on Amazon. Studies show that titles with clear benefits and relevant keywords can boost click-through rates by up to 35%. Including key features like dosage, form (e.g., capsule, powder), and target benefits (e.g., immune support, joint health) in bullet points increases conversion rates by up to 20%. Additionally, Amazon’s A10 algorithm favors listings that are both keyword-rich and customer-focused, meaning well-optimized copy helps improve organic rankings and sales performance over time.

Sample Title (within 200 characters):

Turmeric Curcumin with BioPerine® – 1950mg – Natural Joint Support & Anti-Inflammatory Supplement – High Absorption – Non-GMO, Gluten-Free – 90 Capsules

Here are a sample of bullet points on Amazon for the supplement items.

2. Customer Reviews and the Vine Program

Customer Reviews are feedback left by buyers about their experience with a product, while the Amazon Vine Program invites trusted reviewers to share honest opinions on new or pre-release products in exchange for free samples. For supplement products, these reviews play a critical role in building credibility and trust, especially since buyers are cautious about what they consume. Positive, detailed reviews improve conversion rates, enhance organic ranking, and help new supplement brands gain early traction by showcasing social proof.

Importance of Reviews

Reviews are a cornerstone of success when selling supplement products on Amazon. Customers, including myself, rely heavily on reviews before making online purchases. For any online product, having good reviews is essential to build trust and drive sales.

Leveraging the Amazon Vine Program

To kickstart reviews for our new product, we enrolled it in the Amazon Vine program. We allocated 30 units for this program, and out of those, we received 28 top-notch, five-star reviews. These high-quality reviews have significantly boosted customer confidence and encouraged more purchases.

Merging Reviews from Existing Products

Another strategy we employed was merging our new product with an existing variation that already had over 40+ reviews. This previous product, also sold on Amazon, allowed us to display all reviews together, creating a higher review count for the new listing. If you have older products with strong review ratings, consider merging them with your new product to boost perceived credibility.

3. Grab the Loyal Customers with Subscribe and Save Strategy

The Subscribe & Save strategy on Amazon allows customers to schedule recurring deliveries of supplement products at a discounted price. This not only improves customer retention and lifetime value but also ensures steady, predictable sales for sellers. For supplements—products often taken daily or monthly—this program encourages repeat purchases, increases brand loyalty, and helps maintain a stable sales velocity, which positively impacts organic ranking and overall business growth.

Building Loyal Customers with Subscribe and Save

The Subscribe and Save feature is a powerful tool for creating loyal customers and ensuring long-term profitability. For our vitamin D3 drops, we offer two pricing options in the buy box: a one-time purchase at $9.99 and a Subscribe and Save option with a 10% discount. This means customers who subscribe will receive a 10% discount on their next purchase.

Results of the Subscribe and Save Program

The results of this strategy have been impressive. By checking the performance dashboard for our ASIN and selecting a date range, we can see the subscription count growth. On March 1st, we had only 7 subscriptions. By March 8th, this increased to 12, then to 17 by March 15th. Gradually, the subscription count has grown, reaching 39 by the time of this analysis. This steady increase indicates that these 39 customers are loyal and will continue purchasing repeatedly.

The efforts we’re putting into advertising, listing optimization, and other changes are all aimed at building this loyal customer base, which will yield returns in the future. The performance dashboard also provides other valuable data, allowing us to analyze and apply different strategies to improve our product’s performance.

4. Push More with Deals, Discounts, and Coupons

Deals, Discounts, and Coupons are powerful tools on Amazon that can significantly boost sales and visibility for supplement products. Offering time-limited deals or discounts can attract price-sensitive customers and create urgency, driving quicker purchases. Coupons, visible on product pages and during checkout, act as an incentive for customers to choose your product over competitors. These strategies increase conversion rates, improve your product’s ranking, and enhance overall customer satisfaction, helping to establish your brand’s credibility and grow a loyal customer base.

Testing Price Points

Pricing is another critical aspect of selling supplement products on Amazon. Initially, our product was priced at $16, but we frequently adjusted the price to test what works best. These changes were based on competitor research and their offerings. For example, we introduced a “get three for the price of two” deal, meaning customers who buy two products get a third one free. We also occasionally offer limited-time deals, similar to some competitors.

Benefits of Price Testing

Testing different price points helps us identify which offers the best results while remaining profitable. By analyzing the outcomes of these deals and coupons, we can determine the optimal price point for our product.

5. A+ Content for Supplement Products

A+ Content on Amazon allows sellers to enhance their product listings with rich media, including high-quality images, detailed descriptions, and comparison charts. For supplement products, A+ Content provides an excellent opportunity to educate potential buyers about the product’s benefits, ingredients, and usage. It also helps in building brand identity and trust by showcasing the product’s quality and value proposition more effectively than standard product descriptions. By creating a visually appealing and informative listing, A+ Content can improve conversion rates, reduce bounce rates, and differentiate your supplement product from competitors.

Current A+ Content and Future Improvements

Our current A+ content is functional but not yet at its best. We haven’t utilized premium A+ content or included a brand story, but we’re actively working on both. Once implemented, we plan to conduct A/B tests to compare the performance of the standard A+ content versus the premium version with a brand story. This will help us identify which option drives better results for our product.

6. PPC Ads Performance for Supplement Products

PPC Ads Performance on Amazon is crucial for driving visibility and sales, especially for supplement products in a competitive market. By strategically targeting the right keywords and optimizing ad campaigns, you can increase the chances of your product appearing in front of potential buyers at the moment they are ready to purchase. Monitoring and adjusting key metrics like ACOS (Advertising Cost of Sale), CTR (Click-Through Rate), and ROAS (Return on Ad Spend) ensures that your ads are performing efficiently. For supplement products, PPC ads can help reach a broader audience, improve brand awareness, and generate immediate sales, all while offering valuable insights into customer behavior and preferences.

Business Report Insights

Before diving into PPC, let’s look at our sales performance in the business report. In the first month of the year, we sold 44 units. This jumped to 107 units in February and soared to 411 units in March—nearly four times higher than the previous month.

PPC Campaign Performance

Our PPC campaigns have also shown significant progress. In January, we spent $200 on ads, resulting in 18 units sold, but with a high advertising cost of sale (ACoS) of 65%. In February, we increased our ad spend to over $600, achieving 55 units sold, though the ACoS rose to 91%. Despite the higher ACoS, our sales were three times higher than January.

In March, we invested over $2,500 in PPC, leading to sales that were nearly five times higher than February. While the ACoS remained high, we continued investing in ads. This decision was informed by a lesson from a previous product. Last year, we sold another product, starting with 64 units in the first month, 61 in the second, and 118 in the third. However, when the client cut the advertising budget, sales struggled for the rest of the year, unable to regain momentum.

Lessons Learned and Current Strategy

This experience taught us not to repeat the same mistake. Even with a higher ACoS, we continue spending on PPC for our new product to establish our brand on Amazon and gain loyal customers. We believe that after six months, these efforts will yield profitable returns.

PPC Campaign Details

For our vitamin D3 drops, priced at $9.99, the average cost-per-click (CPC) is $2.63, which is relatively high but typical for supplement products, where CPCs range from $1.50 to $4 due to market competition. To counter this, we focused on improving our conversion rate. Over the year, we received 1,970 clicks, resulting in 576 units ordered. This translates to roughly one order for every three to four clicks—a strong conversion rate for a supplement product.

In the last seven days alone, we had 218 clicks and 75 units ordered, showing that our conversion rate is improving daily. When CPCs are high, focusing on conversion rate optimization is key to controlling ACoS and boosting profitability.

Advanced PPC Strategies

We’ve experimented with various bidding strategies, including up-and-down bids, fixed bids, and top-of-search placement adjustments. We also analyzed hourly data to apply bidding and budget rules, increasing the budget during peak times. These efforts have helped maximize the effectiveness of our PPC campaigns.

Extra: A Four-Month Journey and Future Plans

This blog covers a four-month journey of selling a supplement product on the Amazon US marketplace, but the work is far from over. We’ve been testing various strategies, including different pricing options, main image variations, A+ content, and PPC campaigns. Over the next two months, we’ll continue these tests to establish a fixed price point and other key elements. For example, after two more months of price testing, we’ll settle on a long-term price and stick to it.

We’re also refining our main image, A+ content, and brand story. After six months, we plan to scale our PPC campaigns with a focus on profitability. For those selling or planning to sell supplement products on Amazon, my six years of experience lead me to this advice: don’t lose hope. Keep investing time, money, and effort into your business, and don’t expect instant returns. Success on Amazon requires patience and persistence.
