Delicious fresh Blueberries at a fraction of the price!
Size: 1 PT
Absolutely delicious, and so much less expensive than at the store!!
Beautiful plump Blueberries that taste great!
At first I wasn't sure, since they cost so much less than at any store, but I decided to try them just in case they turned out to be good, and to leave a review for others.
They came inside a foil-interior brown bag, each with rubber bands to keep them closed (great idea) and with a frozen water bottle to help keep them cool! That was a very nice added bonus.

Tastes Great
Flavor Name: Variety Pack, Size: 12 Fl Oz (Pack of 12)
’ve been really impressed with the Bloom Nutrition Sparkling Energy Drink. It strikes a great balance between effective energy and a clean, refreshing taste. The fact that it contains 180mg of natural caffeine gives a noticeable boost without the jittery feeling or crash that some other energy drinks tend to cause. It feels smooth and steady, which makes it perfect for mornings or a midday pick-me-up.
One of the standout features is that it’s completely sugar-free, yet still manages to taste flavorful and crisp. The light carbonation adds a refreshing touch, and the variety of fruit flavors keeps things interesting without being overly sweet or artificial. It’s clear that a lot of thought went into creating a drink that feels both enjoyable and functional.
I also appreciate the added ingredients like prebiotics and plant-based caffeine sources, which make it feel like a more mindful alternative compared to traditional energy drinks. It’s nice knowing you’re getting a bit more than just caffeine.
Overall, Bloom has created a great option for anyone looking for clean energy, good flavor, and a healthier approach to staying energized throughout the day. Highly recommend!

My New Favorite Energy Drink
Flavor Name: Variety Pack, Size: 12 Fl Oz (Pack of 12)
I’ve made the smart switch from sugary energy drinks to Bloom Nutrition Sparkling Energy, and it’s a change I’ll never regret! The variety pack keeps my options fresh, and every flavor is crisp, light, and absolutely delicious. With 180mg of natural caffeine, I enjoy a smooth, steady energy boost without the jitters or crashes that come with other brands. Packed with green coffee bean extract, green tea extract, and prebiotics, I feel great about fueling my body with this drink. Zero sugar and genuinely tasty? Yes, please! I can't recommend it enough! 😊

Great choice!! All flavors!!
Flavor Name: Variety Pack, Size: 12 Fl Oz (Pack of 12)
This is a winner!! Great taste!! I just so happened to purchase this at the hospital in the snack room. I took a chance on it because I was thirsty. And I am glad I made this choice. It has caffeine in it. Not enough to notice but it helped me stay woke during the time I was there. This is good, so give it a try.

Healthy and delicious
Flavor Name: Variety Pack, Size: 12 Fl Oz (Pack of 12)
Let’s compare to Alani! I was a HUGE Alani consumer, wanted something healthier, tried more energy drinks than I can count until I ended up HERE with Bloom! I am very happy about these :)
These have 180mg of green tea caffeine, Alani has 200mg. After switching from Alani to less mg caffeine energy drinks; I cannot handle an Alani anymore! They give me anxiety, and make me feel really bad.
Flavor wise!! Delicious. But let’s compare to an Alani.
Bloom peach mango, in comparison to a juicy peach Alani is a much milder sweetness and doesn’t come across too overwhelming while still being just as delicious, and in my opinion they taste even better!
Bloom cherry lime, in comparison to Alani cherry twist is a HUGE difference. Alani’s leaves a weird chemical after taste that I cannot get past and makes me refuse to drink them. I am a loverrrr of cherry lime drinks, and this one does have a slight medicinal taste, but it’s more like a sweet tart in comparison. It’s still a win to me!
Bloom strawberry watermelon is comparable to Alani watermelon wave!! But not as tart/sour. I am going to be honest in saying this flavor on both brands is probably my favorite! They both remind me of a jolly rancher. Again, I am much happier enjoying the bloom version.
Bloom raspberry lemon is not actually comparable to any Alani in my opinion, I would reach to say Alani pink slush, ONLY because they both have a different sweetness that comes with a “pink” brand drink. I used to love pink slush until the flavor became nothing but carbonation to me.. I can’t be sure but feel the ingredients were changed somewhere along the way, as Alani tends to do. But I really enjoy the flavor of raspberry lemon Bloom, and you can definitely taste BOTH flavors.
Alani is zero sugar, B12, B6 and biotin, 200mg caffeine and artificial sweeteners. After drinking them for maybe three years, I got burnt out.
Bloom has zero sugar, 180mg caffeine, B6, B12, apple cider vinegar, prebiotic fiber, no artificial flavors or color or aspartame.
You can decide for yourself, but this is a side by side comparison:)
