Smoothie King is giving its protein lineup a major makeover—and this time, there's plenty of sparkle involved.

Starting October 7, 2026, Smoothie King is introducing its new Pretty, Pretty Protein Smoothie, a strawberry-and-banana protein smoothie served in a limited-edition rhinestone-covered cup at select participating locations.

But the promotion doesn't stop at the sparkly cup. Customers who purchase the featured smoothie and share a qualifying photo or video on Instagram or TikTok could also be among the first 500 people to receive a $25 Smoothie King gift card.

The promotion is available for a limited time and while supplies last, so anyone interested in the bedazzled cup or gift card giveaway will want to act quickly.

What Is the Pretty, Pretty Protein Smoothie?

The new Pretty, Pretty Protein Smoothie is a 20-ounce strawberry-and-banana smoothie designed to pack a significant amount of protein into a single drink.

According to Smoothie King's launch announcement, one 20-ounce smoothie contains:

• 47g of protein

• 5g of fiber

• 0g of added sugar

• Strawberries

• Bananas

The smoothie is served in a limited-edition 20-ounce cup covered in rhinestones at participating locations while supplies last.

So the promotion combines two very different trends: the continued popularity of protein-focused drinks and the current resurgence of bedazzled accessories.

Smoothie King says the goal is to make protein not only nutritious but also more fun and expressive.

FREE Rhinestone-Covered Cup

The biggest attraction may actually be the cup.

When you order the Pretty, Pretty Protein Smoothie at a participating location, the drink comes with a limited-edition rhinestone-covered cup at no additional charge, while supplies last.

The cup is 20 ounces, matching the size of the featured smoothie.

However, there is an important distinction:

The rhinestone cup is not available at every Smoothie King location.

The promotion is limited to select participating locations, and individual stores can run out of cups before the overall promotion ends. Smoothie King specifically warns that supplies are limited.

Tip: Call ahead if the cup is your main reason for going

Because the cup is a limited-supply item, it may be worth checking with your local participating Smoothie King before making the trip.

The company says cups can run out at individual locations even before all 500 gift cards have been awarded.

You Could Also Get a $25 Smoothie King Gift Card

Here's the extra part that makes this promotion more interesting.

After purchasing the Pretty, Pretty Protein Smoothie, eligible customers can post a photo or video of their smoothie on a public Instagram or TikTok account.

To qualify, the post must:

• Show the Pretty, Pretty Protein Smoothie

• Be posted on Instagram or TikTok

• Be publicly viewable

• Tag @SmoothieKing

• Include #prettyprettyprotein

If you're among the first 500 qualifying guests whose posts are verified by Smoothie King, you'll receive a $25 Smoothie King gift card via direct message

The giveaway has a $12,500 total prize pool

Smoothie King states that 500 qualifying guests can each receive a $25 gift card.

That means the total value of the gift cards is:

500 × $25 = $12,500

The gift card is intended for a future Smoothie King purchase, so this is effectively a chance to turn your social post into $25 toward your next visit

How to Claim the FREE Cup

Getting the rhinestone cup is relatively simple:

Step 1: Find a participating Smoothie King

The promotion is available only at select participating locations.

Step 2: Order the Pretty, Pretty Protein Smoothie

Order the featured 20-ounce Pretty, Pretty Protein Smoothie.

Step 3: Make sure you're ordering in person

The promotional terms specify that qualifying purchases must be made in-store or through the drive-thru.

The rhinestone cup promotion is not available through order-ahead, online ordering or third-party delivery.

Step 4: Get the limited-edition cup

If the location still has promotional cups available, your smoothie will come with the rhinestone-covered cup at no additional cost.

How to Enter the $25 Gift Card Giveaway

Want to go one step further and try for the $25 gift card?

Follow these steps:

• Purchase the qualifying smoothie

You need to purchase the Pretty, Pretty Protein Smoothie at a participating location.

• Take a photo or video

Capture your smoothie, preferably showing off the rhinestone-covered cup.

• Post publicly

Upload the photo or video to your public Instagram or TikTok account.

• Tag Smoothie King

Tag @SmoothieKing and include:

#prettyprettyprotein

• Keep the post public

Smoothie King says the post must remain public until it has been verified. You may also need to provide proof of purchase, such as your receipt.

• Be one of the first 500

Smoothie King will verify qualifying posts in order. The first 500 eligible participants receive a $25 Smoothie King gift card via DM.

Important: The $25 Gift Card Is NOT Guaranteed

This is probably the most important detail to understand.

Buying the smoothie does not automatically give you a $25 gift card.

There are two separate benefits:

Purchase the smoothie → Get the rhinestone cup while supplies last

Purchase + qualifying social post + verification + early entry → Chance to receive the $25 gift card

Only the first 500 qualifying guests receive the gift card. Once all 500 rewards have been awarded, the giveaway ends. The overall promotion also ends when the promotional period ends or supplies run out, whichever comes first. 

When Does the Promotion Start?

The Pretty, Pretty Protein promotion begins October 7, 2026.

Smoothie King says the promotion runs while supplies last or until 500 gift cards have been awarded, whichever comes first.

Key dates

Launch: October 7, 2026
Availability: Limited time
Rhinestone cups: While supplies last
$25 gift cards: First 500 qualifying guests

Because there isn't a guaranteed end date for the cups, waiting too long could mean your local store has already run out.

Who Is Eligible for the $25 Gift Card?

The social giveaway is open to:

• Legal residents of the 50 United States and Washington, D.C.

• 18 years of age or older

Employees of Smoothie King, its franchisees and agencies, as well as their immediate family and household members, are excluded.

The cup promotion itself is tied to participating Smoothie King locations, so availability can be narrower than the overall geographic eligibility for the social giveaway.

Online Ordering Doesn't Qualify

This is another detail worth highlighting.

For this particular promotion, Smoothie King says qualifying purchases must be made:

✅ In-store
✅ Drive-thru

But not:

❌ Order-ahead through the app
❌ Online ordering
❌ Third-party delivery

That's especially important for customers who normally use Smoothie King's mobile ordering.

If you're specifically going for the rhinestone cup or $25 gift card giveaway, ordering in person is the safer option. 

What's Special About the Nutrition?

Beyond the promotional cup, the smoothie itself is designed around Smoothie King's protein-focused menu strategy.

The 20-ounce Pretty, Pretty Protein Smoothie contains 47 grams of protein and 5 grams of fiber, while listing 0 grams of added sugar.

Smoothie King has increasingly emphasized protein and nutrition-focused options. The company says it has spent more than 50 years developing smoothies with nutritional experts and currently offers different categories designed around goals such as fitness, wellness and weight management.

The brand also says its smoothies are built from the ground up with nutritional considerations in mind, rather than simply adding protein to an existing beverage.

Important: Nutritional needs vary from person to person, so the nutrition numbers shouldn't automatically be interpreted as a recommendation that the smoothie is appropriate for a particular diet.

Smoothie King's Pretty, Pretty Protein Smoothie is a limited-time promotion that combines a new high-protein smoothie with a free rhinestone-covered 20-ounce cup, while supplies last.
