We found a deal on David Protein Bars that’s scandalously sweet: 20% off

We got the skinny on this deceptively delicious deal.

David Protein Bars — the high-protein, low-calorie bars that recently found themselves under legal scrutiny — are back in the conversation just in time for Amazon’s Big Spring Sale, now marked down up to 20% off.

In the lawsuit, the brand is accused of misrepresenting the bars’ calorie and fat content. But, as Peter Rahal, founder of David Protein, has explained to news outlets and on his own social platforms, some don’t understand how calories are measured.

David Protein Bars contain an ingredient known as Esterified Propoxylated Glycerol (EPG), a plant-based fat alternative that delivers the texture and mouthfeel of fat without being fully digested by the body. Calories remain minimal while the bar still tastes indulgent.

Each bar gives 28 grams of protein for roughly 150 calories, which explains why shoppers keep clicking “add to cart.”

David High Protein Bars

The flavors read like a bakery case: Chocolate Chip Cookie Dough, Peanut Butter Chocolate, Fudge Brownie, Blueberry Muffin. Sweet enough to feel like a reward, clean enough to eat after your workout.

Beyond the headlines, many shoppers (more than 20,000 this past month alone on Amazon) are still adding the bars to their cart.

“The bar is perfectly chewy with a slight crunch to give it some texture,” one happy customer wrote, while another stated the taste was “great.”

The discount just makes the protein bar more delicious. If you haven’t tried them yet, this is your chance to see what all the hype is about.

What is Big Spring Sale?

This annual Amazon Spring Sale offers deep discounts on bestsellers and everyday essentials. The seasonality of the sale makes it prime (pun intended) for savings on outdoor products, spring cleaning needs, tools and home essentials, plus all the great discounts you’ve come to expect from a Prime Day-like event.

How long is Big Spring Sale?

Amazon’s Big Spring Sale is a marathon compared to the retailer’s shorter deal events. Shoppers can take advantage of seasonal discounts running from Wednesday, March 25 through Tuesday, March 31.

Do you have to be an Amazon Prime member to shop?

Unlike Prime Day in July, this event is open to everyone who shops on Amazon. However interested shoppers can grab a 30-day free trial to try Prime, and its many benefits with no strings attached, and gain access to exclusive deals, special “Prime” badges on select items and the added convenience of fast, free shipping.

What are the best deals?

From reporting on Amazon sales for years, we can tell you for certain that Big Spring Sale is the ideal period to stock up on household essentials, refill your skincare empties, save on the best vacuums to save your spring cleaning projects, and comb through the massive catalog of Amazon best-sellers.

When is the next Prime Day?

Already wondering when Amazon’s next Prime Day is? Prime Day takes place in July each year, so it’s safe to assume it will take place in mid-July 2026 — similar to previous years.
