Flagged as a product to avoid

2 of 12 research runs entered this as a product to avoid rather than a pick.

It relies mostly on sugar alcohols to keep sugar low, which a dietitian review flags as 'can be troublesome' for digestion - the exact failure mode that emerges after months of ownership - and its macros-per-calorie story collapses under scrutiny. Kirkland Signature fills the same budget role without the gut risk.

Illuminate Labs finds it underperforms on protein dose and healthiness despite winning on price, and a dietitian review flags that the bars lean heavily on sugar alcohols and similar sweeteners. People cross-shop it because it is one of the cheapest boxes on the shelf, but the macros and ingredient quality do not hold up under a years-long lens; Barebells or Quest are the better buy.

These are still some of the cheapest protein bars out there and They have an amazing taste of them. Did your protein bars come in boxes of six and they come in a variety of different flavors, but I think that the chocolate deluxe is one of the better flavour that they have.

I got this one of the pure protein bar and it was good. To me it’s not as sweet as the zigzag one was. Plus it has more protein and less calories than the zigzag one. It has a good taste and doesn’t taste like protein.

If you love sweets and you're looking for an easier way to get your sweets, but also get your protein and not break your diet, then this is just such a great option. And some quick stats on this protein bar. There's 200 calories here, 20 grams of protein and um four grams of saturated fat. So, such an amazing bar. The lemon cake is great. Um, I'm also a big fan of their chocolate peanut butter pure protein bars.

I used to love eating these bars but they unfortunately cause a blood glucose spike in me that’s very equivalent to eating straight up sugar. I believe the maltitol they contain is responsible for that. I’m not diabetic, but I had a CGM on for some time and was just trying to look for patterns as well as foods that cause spikes for me. Sadly, I had to get rid of these. The quest double chocolate is my go to bar and thankfully causes no issues with blood glucose spikes.

Overall, it's an all right bar. It depends on whether you're someone who likes peanut butter and whether you're someone who likes chocolate and peanut butter together. For me, I don't have as much peanut butter as some people who like really love it.

The chewy choc chip tastes like playdoh but the peanut butter and chocolate peanut butter caramel are really good. I havent tried the other ones. Edit i totally forgot, ive also tried the chocolate deluxe and salted caramel ones which were both alright. The salted caramel had a lot of potential but it was weirdly hard and the chocolate deluxe was good but not as good as the choc pb or choc pb caramel.
