Great taste but cannot use
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
First time trying for dental care. Really enjoy the taste only drawback taste doesn’t last long. However, it’s better than other sugar substitutes which my stomach does not like.
Glad I signed up for the three pack sub. Great product! Recommend.
May 16, 2026 Update: Unfortunately I cannot use this product after the initial trial every time I chew on these i experience stomach issues so the three pack I purchased will need to find someone that can use them or throw out.

Powerful lasting peppermint flavor & the xylitol fights plaque!
Flavor Name: Spearmint, Size: 55 Count (Pack of 6)
The gum has a powerful peppermint taste – very refreshing. The flavor lasts a long time. The main reason that I bought this gum is because it has 100% xylitol. Xylitol helps fight plaque buildup. I have only had the product one day, so I can't say that it works, but I read many reports before I bought the gum that xylitol is excellent for fighting plaque buildup. It also has no sugar. It's vegan and it has only five calories per two pieces. I have so far only chewed one piece at a time. One piece seems plenty for me. I've read that people need from six to ten grams of xylitol per day to effectively fight plaque. So, this gum needs to be chewed accordingly. Many people chew after every time they eat. I am happy with this purchase.

Only protein shake I've found that doesn't cramp my stomach
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
I've tried the vanilla, strawberry and chocolate, and chocolate is by far the best. It's not too sweet (where as the vanilla and strawberry were). It doesn't have any extra whey concentrate or caseinate or soy or whatever added to it to boost protein. Brands that do that mess up my stomach, giving me bad stomach cramps. This is just highly filtered milk, and lactase enzyme that tackles the lactose sugar left behind after filtration. Maybe that's the secret. (I can drink normal milk and not get cramps. But, whey protein isolate and other things give me cramps.) This has become a go-to in a protein diet I'm on. I'll have one for breakfast with some coffee. That lasts me until lunch. If not, I'll simply have another 2 hours later. They're each less than 200 calories, so it's not too bad having another if it staves off hunger. I find I eat a smaller lunch. I might have another one for a mid-afternoon snack. Then I'll have a normal dinner. Basically I'm replacing bigger meals and a breakfast with 2-3 smaller calorie protein shakes. And the protein keeps me satisfied. (unlike something like slim fast that's just all sugar and ramps up your insulin). They're a bit pricey (almost $4/bottle). But, I'm cutting back on my grocery bill as well. So, it's balancing out. I figure I could be spending $12/day on fast food or some other garbage that makes me fat. Instead I'm drinking 2-3 of these a day, and am down 10lbs over a month. I'll stick with these.

No Chalky Aftertaste!
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
I've tried many different kinds of protein drinks, and almost all of them have either an unpleasant consistency or aftertaste. This Core Power Chocolate Protein Shake is by far the best I have ever tasted. If you place your cold drink in the freezer for about an hour and a half before drinking, it becomes slushy like a real milkshake. It is delicious and high in protein. I drink one just about every day for a quick and easy lunch.

still the best but a big price premium
Flavor Name: Chocolate, Size: 14 Fl Oz (Pack of 12)
Still the best tasting out there. drinking these is not a chore. easy open bottle. the price is the only thing, These are great for lunch replacement where you actually look forward to drinking it. every now and then my kids will get to them. it really is like a really good chocolate milk closer to a milkshake. but yea price is a touch excessive, but this protein level is the best price per gram after i ran the numbers compared to theor other products.
