Copywriter for Nutritional & Dietary Supplements

How to Craft Sales Copy That Persuades Customers to Reach for Their Wallet

posted under Copywriter for Healthcare Businesses (physicians, hospitals, etc.)

For many years diet and nutrition information has captivated modern day audiences. And for good reason. Who among us can honestly say their diet is perfect and they don’t need to shed a few pounds?

As you might expect, plenty of products have been created to meet the strong demand for better health and fitness. That’s fine if you’re a consumer; you have more choices and presumably lower prices due to competition. But if you’re the inventor or distributor for one of those products, you face the challenge of how to distinguish your diet/nutrition brand from what is an exceptionally crowded field.

Standing out in the crowded dietary and nutritional supplement industry presents a formidable challenge.

Good Copywriting Makes a Difference

Ever receive a mailing about a diet product or nutritional supplement? They tend to be long-winded affairs with lots of information to tempt you to buy.

While other products can get by with a bold headline and a few descriptive sentences, diet and nutritional products do best when they’re explained in detail, whether marketed online, through direct mail or any other way.

Think of them as the counterpart to those long-form 30-minute infomercials you see on TV. And because of their length, the quality of their copywriting can make a substantial difference in how many leads and sales they generate.

To be effective in selling your nutritional products, your promotional copy must be interesting, engaging and persuasive.

What to Include in Your Copy

Writing copy for your diet or nutritional product deserves your best thinking. Consider including each of these components and understand the objectives they serve:

  • Powerful Headline – The purpose of the headline is to grab attention and deliver the reader to the first line of text. The headline should be thought-provoking and intriguing. It should also tout a key benefit whether that’s weight loss, bigger muscles or improved health. Feel free to also incorporate subheads to state additional benefits and break up big blocks of copy.
  • Narrative Copy – This is where you get to tell your product’s story. What does your product do, how does it do it and why is it better than competing products?
written testimonials

Written testimonials from satisfied customers can make a compelling case for your nutritional products.

  • Testimonials – What could be more compelling than someone telling you their personal story of success in their own words teeming with emotion and pride? According to Kissmetrics, a marketing blog, “The power of testimonials lies in their objectivity. That is, someone outside of the brand does the talking, so in theory, the credibility is higher.”
  • Case Studies – Think of case studies as long-form testimonials or anecdotal evidence to support your claims. Highlight the struggles and describe the health-based results. If your case studies are written about people who are representative of your target audience, they can make the reader think, “If she had success with this product, then I will too!”
promotional copy

Favorable reviews on social media can be leveraged into your promotional copy on your website, in brochures and in ads.

  • Physician Claims – If you have any doctors who support your diet or nutritional product, quote their comments about it, especially if they can speak to its effects on the health of their patients.
  • Social Proof – If you’ve received any positive reviews online or been mentioned by a prominent blogger or voice of authority in the diet and nutrition industry, those endorsements should be featured.
  • Statistics – Got any numbers to support your claims? Don’t be afraid to get specific. Saying you lost 32 lbs. in one month is a lot more impactful than saying you lost a lot of weight.
studies and statistics

Claims that are supported with legitimate studies and statistics become more credible.

  • Studies – Is your product the result of a scientific breakthrough? If so, provide the facts. If you have information garnered from pilot studies or clinical trials with your product, they’re worth including. They’ll help bolster your benefit statements.
  • Credentials – Anything that can increase trust in your product and your company is important. Whether it’s membership in a medical association, educational credentials, seals of approval or awards won, they all belong in your copy.
  • Bullets – People read lists. Summarize you key benefit statements with highly persuasive bullets that cut right to the chase.
  • FAQsFrequently asked questions allow you to restate your most important selling points in an easy-to-read, Q/A format. They’re also an opportunity to remove or mitigate the reader’s biggest fears, whatever they may be, by addressing them in a simple, straightforward manner.
  • Images – Product pictures are good, including pictures of your product’s packaging. Those help build your brand. So do pictures of plants, if they’re part of the ingredients. Medical photos also work. And you can even include photos (or videos) of the people giving testimonials, which will help increase the credibility of their statements. Finally, there’s the old standby of before and after photos. Seeing is believing when it comes to people who’ve shed pounds, gotten buff and improved their overall health.
add visual interest to copy

Use product photos, ingredient photos and even customer photos to add visual interest to your copy.

  • Call to Action – After you’ve told the reader all of the wonderful things your product can do, you need to ask for the sale. Spell out what you’re offering and don’t hesitate to restate why they should place their order NOW. Powerful closing lines prompt a response.
  • Deadline – If you can add some immediacy to your offer, you’ll convert some of the procrastinators into buyers. It can be a special introductory price available for a limited time or the incentive of a bonus gift for which there are a limited quantity.
  • Order Information – Be clear in spelling out the exact steps for placing an order, whether by phone, mail or online.
  • Guarantee – Take away the prospect’s fears by eliminating risk. A money-back guarantee if the customer doesn’t see the promised benefits is a good way to reduce friction in the sales process.
Supplements made from food

If your supplements are made from food, don’t just list the ingredients, show them for added impact.

Your Copy Must Be Authentic

One of the reasons why longer copy works best for dietary and nutritional supplements is that people are a bit wary of these products. They’ve probably tried other products that didn’t accomplish their stated goal, and they want to be prudent in making decisions about something they’re putting into their bodies.

transparency and authenticity

Strive for transparency and authenticity in describing your product’s health benefits in your copy.

They’re skeptical and need convincing. By providing a wealth of information, you appear to be transparent. Your statements become more believable. You’re demonstrating you have nothing to hide.

According to NutraScience, a vitamin and supplement manufacturing company, “Marketing studies have been able to demonstrate, time and again, that authenticity and transparency can go a long way when trying to connect with your customers.”

the right tone for selling

Consider the tone of your words in selling nutritional products. Avoid sounding “salesy.”

Set the Right Tone

When you write copy to sell diet aids, vitamins and nutritional supplements, the tone you use is important. What you say is as important as how you say it. While promising fast, substantial, near-miraculous results may initially move products off the shelf, it’s not a good long-term strategy.

Avoid writing with hyperbole. You don’t want to sound “salesy” or “over the top.” Pushy may work for selling cars but it creates doubt for dietary products. If it sounds too good to be true, don’t say it!

Avoid hyperbole

Avoid hyperbole. A straightforward presentation of the facts will be more compelling.

Instead, lean toward a straightforward presentation of the facts, supported by studies and provable results. And leave the statements of emotional delight for your customers to say in their testimonials.

Tell Your Personal Story

In your copy, consider telling your own story if it demonstrates your personal, empathetic understanding of the struggles your customers face.

Will Cartright in an article about marketing nutritional supplements poses the following questions and answer:

“Why did you get into the supplement business in the first place? It was likely a passion for health and a desire to share that passion with others.

Perhaps vitamins or supplements have helped you to overcome an illness, become a better athlete or substantially raise your quality of life?  “Your story and connection to a healthy lifestyle will inspire others to seek the same, and they’ll feel a more personal connection to your business and brand.”

Write your personal story

Write about why you began selling nutritional supplements if it demonstrates your personal struggle and connection to your products.

From Concepts to Written Words

If you know your product inside and out but you’re struggling to put those words on paper, you are not alone. Some of the nation’s best salespeople are phenomenally articulate in describing what they’re selling, but ask them to compose a sales letter and they’re paralyzed. Hey, we all have our strengths and weaknesses.
