"I love mixing it with a banana, it makes it a bit sweeter and it's perfect!"

"This spirulina powder is fantastic for my health. I use it for face masks, plant food, and as a smoothie addition. It's a great detoxifying food!"

"I used this for my aquarium fish and snails, and they absolutely love it! They've become energetic and are growing healthily, so I highly recommend it for anyone looking for aquarium-safe food ingredients."

"I'm extremely satisfied with the quality of this product. I enjoy it, especially in my smoothies. The powder mixes well and has a fresh, earthy taste that's perfect for my green smoothie recipes. Plus, knowing about the sustainability features, I feel good about my choice. I highly recommend it for anyone wanting to boost their nutrition naturally!"

"As a first-time buyer of spirulina powder, I was impressed. I did my research and chose this organic, high-quality product. Upon opening the bag, the freshness was evident from the color, scent, and how it mixed with my water. I feel safe taking this product and even bought others from the same company."

"I love that this spirulina is organic and recognized as a nutrient-dense supplement. My household consumes it regularly. I breed Boston Terriers and feed them a balanced organic raw diet, so this spirulina is essential for both my pets and us. It can be added to smoothies, beverages, soups, or mixed with other supplements."

"I absolutely love this product! The quality and nutrition are outstanding, and it offers a great value for my health."

"After using it for a month, I'm sleeping 6-8 hours a night for the first time in five years. This spirulina has been a God-send for my scalp psoriasis, which is finally clearing after six years of struggle. I highly recommend this clean and reliable version!"

"I've been taking spirulina capsules regularly, and I appreciate its high digestibility and the fact that it helps combat carbon dioxide in the atmosphere. It’s fascinating to know about its historical significance, and I'm thrilled with the convenient packaging and organic quality."

"Both my husband and I have been using Pure Hawaiian Spirulina Powder for years and find it to be the best in quality, freshness, and taste. We notice a decrease in energy when we run out. The taste is good, especially mixed with orange juice, though blending can be a bit tricky."

"I've incorporated Nutrex Hawaii Pure Hawaiian Spirulina Powder into my daily routine. I appreciate the authenticity of the product, even if it has a distinct fishy smell. It really helps with cleansing and detoxifying, and I love the great value it offers. I plan on ordering more!"

"As a first-time spirulina user, I chose this one due to its Hawaiian source. I mix it with strong-tasting foods since I’m not fond of its flavor. While the smell is less intense than other brands, it tends to settle at the bottom of drinks."

"I've been using Carlyle organic spirulina for a couple of years and I’m hesitant to express my true feelings because I don’t want the price to go up or the availability to decrease! But honestly, this is something more people should incorporate into their diets for gut health, sustainable protein, and micronutrients. It's definitely high quality! I add 24 grams to my morning smoothie, and the taste is great—no fishiness at all. The price is amazing for the kilo size, and it's the best value I’ve found!"

"I mix my spirulina with grape juice. It has a strange smell but tastes great when combined with the juice. I think this product really does enhance my smoothies!"

"I take a tablespoon of this every day in my protein smoothie. My nutritionist recommended it, and after a year, my stylist commented on how much thicker my hair is. Now, I wear it down instead of up!"

"I bought this product to add to my juice. I love that it doesn’t interfere with the taste while adding nutrients, and my juice looks so pretty!"

"Not a fan of the price, but the product is great. The color is amazing, and it has ZERO taste. I use it to make my daughter blue 'gatorade' since she can’t have the name brand with all the dyes. It looks just like what the rest of her soccer team was drinking but is way healthier. Total win!"

"I used this to make a Bluey themed cake for my toddler, and the blue was just right. It mixed well into the frosting and had a pleasant taste."

"Having never supplemented with spirulina before, I wasn't sure what to expect. I always look for organic products, so I decided to give Bulk Supplements a try! The product arrived very quickly, and it was impeccably sealed and obviously potent. The color is a deep, rich blue-green, and the flavor is pretty much what you'd expect from spirulina: intensely green and 'aquatic'. I rather like the flavor, but others find it slightly unpalatable. A week into adding this to my morning green drink, I've noticed a spike in energy (without caffeine) and a significant decrease in sinus pressure. I'm SOLD and will definitely be purchasing more supplements from Bulk Supplements. They are affordable, high-quality, and organic, and their customer service is on point."

"I love spirulina! This product mixes well into liquids and smoothies. I can taste it a little bit, but it isn't bad. I definitely feel healthier when I use this. I did transfer it into a dark glass jar for storage to make it easier to use and less dusty than trying to get it out of a bag."

"When I tell you I swear by this product, I 150% do. I'm that person who generally writes reviews when products are excellent. I immediately saw effects after the second day of usage. Joint pain due to inflammation in my ankles subsided, and I experienced some appetite suppression. I usually mix it into a green smoothie with ice and cold water, adding 1.5 tsp for a slushier consistency. However, I caution you to not take more than a tsp at one time; I mistakenly took a tablespoon and OMG, instant diarrhea and loss of appetite. If you mix it as a smoothie, preferably a juice blend, you can barely taste the product. I tried it with a Premier Protein Drink, and it didn't mix well and was pretty thick. I love LOVE this product and brand and will continue to buy."

"I really appreciate the generous amount of spirulina compared to tablets."

"After taking half a dose for six days, I noticed increased energy and less hunger. I'm excited to start the full dose!"

"I've been using this for years and find it a good price. My son also uses it."

"I’m really impressed with spirulina powder! It’s packed with nutrients and provides me with a natural energy boost throughout the day. It dissolves easily in smoothies or water, and I feel great knowing I’m getting a healthy dose of protein, vitamins, and minerals. It’s been fantastic for supporting my immune system and overall well-being. I highly recommend it for anyone wanting to enhance their daily nutrition!"

"I’ve tried spirulina before without any noticeable effects, but with Vimergy spirulina, I felt an increase in energy right on the first day. Although the capsules are a bit large, they’re easy to swallow. I noticed the label suggests taking it 1-2 times a day, and with the positive results I've experienced, I’m excited to increase my intake. My body is truly loving this!"

"Every product I’ve purchased has been of excellent quality. There are no funky ingredients, which really won me over! I love using spirulina in pineapple juice with ice during the summer; it’s refreshing! I also incorporate it into my energy bars and make an elixir drink for my thyroid health. Plus, there’s no fishy aftertaste, which is a huge plus!"

"I absolutely love this spirulina powder! After a few weeks, I've noticed a difference in my energy levels and overall well-being. It mixes easily into smoothies, juices, or just water without any clumps. I appreciate that it's made from 100% pure spirulina with no fillers or artificial ingredients. The earthy taste is pleasant, and I've seen improvements in my skin, digestion, and immune system. It's now a must-have in my kitchen, and I highly recommend it for anyone wanting to boost their health naturally."

"While there is no lie that this stuff has a very fishy odor, it's still one of the best spirulina powders out there. I love adding it to my smoothies for its health benefits and knowing I'm purchasing the real deal is a plus!"

"I was a bit disappointed as all my baby's brine shrimp did not survive in this spirulina powder, and I can't return it. I wouldn't recommend it for raising brine shrimp. The smell isn't great to eat, and I'm unsure why it's used for nutrition."
