Customer Reviews

I have a health condition in which I have to eat like a diabetic. It is hard for me to eat all the vegetables I need in one day. This product helps me accomplish that task. I simply mix in my protein drink and off I go. The fact that it is organic is a plus. I am concerned about vegetables that are GMO's because studies prove that you lose magnesium when you alter leafy greens. This allows me to get the mag I need so I don't lose calcium as a consequence.

Great deal
This is another example of the excellent value you get from Bulk Supplements. I found the spirulina to be as good as much more expensive brands.*

Add to my smoothies...
Looks/smells exactly like I would expect. Very dark green. I add it to my smoothies in the morning for an extra "punch" of nutrients.*

Great Energy Food!!!
Spirulina is an energy food for me. The Bulk Supplements product gives me the same results as my former product at a much lower cost.

If you struggle with the flavor try adding a couple tablespoons of fresh lime juice and a squirt of honey. Mix with a small battery powered coffee frother and drink with a straw. Num!!

Good Tastng
This spirulina is really good tasting, sort of has a meaty-ness to it that is nice on the palette.
This goes well with chocolate powder in a smoothie, I know it may sound gross but try it, it's really good. The spirulina mellows out the chocolate so you either don't need to add any sweetener or very little. So you get this nice, hearty protein packed superfood shake that tastes good and is good for you.

I was afraid to try this at first, I kept reading all this great stuff about spirulina but there was really no info on how it tasted. It is rather pleasant (at least the Bulk Supplements Organic stuff) and now I am looking for more ways to include it in my diet.*

Spirulina (Organic) Powder
Excellent product. Pure wouldn’t order anywhere else. Great customer service. Fast shipping*

Very pure & fine powder
This product was purchased for my horse who has allergies. Vet says it helps esp. Lung. So, I am giving this to him. He does not like the taste so I am increasing to the dose recommend by the vet slowly. He is having trouble breathing so I will come back and update if it helps him. Animals can't have a placebo effect!!*

Organic Spirulina Amazing Superfood!
Bulk does it again with lightning-fast shipping and an unbeatable product! The rich green powder is loaded with nutrients and blends easily in your favorite smoothie. After drinking my smoothie, I actually felt a nice, natural, jitter-free energy boost that lasted for hours. Super satisfied with this superfood! *

On 11/17/2016 Alisan said...

This might be the single best Supplement I use. It is a Superfood and I take it regularly. There are so many proven Heath benefits that I could not even begin to list them.
I crave it. It tastes good. I take it in the morning before workout. I feel energetic throughout the day. Sometimes I mix it hemp power and coconut milk.
I do not recommend taking it at night IF you want to sleep. Do yourself a favor, do a little research on Spirulina and learn what it’s all about. It makes me feel great..
Like all the products I get from BulkSupplements – It’s high quality.

Super Nutrition at a Super Price!
Spirulina is such a versatile nutrition booster, I add it to just about everything. And the larger bag is such a bargain, I can afford to add it to everything! Non-clumping, dissolves easily, and virtually tasteless, it adds protein and minerals to smoothies, omelettes, cooked cereal and baked goods. *

Organic Spirulina

Real Deal!
Nice to find a place to get the real stuff. It only works if it's real. Thank you so much.*

Good Stuff!
I like the purity of the l-arginine. It's important to have the right stuff in order for it to work. Quite happy!*

On 10/26/2016 Thomas said...

Definitely would recommend.
This product mixes very well in water. The smell is bad like an old fish tank that has algae in it but that is exactly the environment spirulina thrives is so it's not surprise. The smell becomes more tolerable but the taste is not bad at all. Just plug nose and drink it with water every morning. Definitely feeling more energetic even though I only get 5-6 hours of sleep each night due to my hectic lifestyle. It helps with my concentration and sense of well being all day long. I just wish BS would be more clear on countries of origin for their stuff. Rumor has it this spirulina comes from China on Amazon. I trust BS to screen their products well but given how prone Spirulina is at absorbing heavy metals, China is not a place I want my spirulina growing. *

Organic Spirulina - Super Food !
I have a stressful job, and do not always eat properly... I use organic spirulina in a protein drink that I prepare for those days when I cannot find time to prepare a fully balanced meal... spirulina provides all essential nutrients and is a complete food... I actually enjoy the taste and the fresh smell... I use spirulina (and chlorella) as a dietary supplement and feel that it helps to promote healthy body functions and gives me natural energy throughout the day... it also helps to give me more stamina to endure the physical demands of my work... I have been taking spirulina and chlorella for several years, and feel more energized and healthy, and it helps with my exercise and weight-loss program... the "Bulk Supplement" products are very good quality and reasonably priced, and I am very pleased with their products.*

Organic Spirulina
Great product!! Fresh!! I was so happy to get it so quickly because I had not realized I was so close to being out. I like to use it in smoothies in the mornings and miss it if there is a lapse of having it. Thank you. will definitely be ordering again! *

Spirulina (Organic) Powder
Excellent product. Pure, secure packaging. Wouldn't order anywhere else. Great customer service. Can't believe I got 250 grams of Spirulina for writing a review!*

Organic Spirulina
This stuff is GREAT!!! I have been using and enjoying the health benefits of Spirulina for years. I was always very particular to order the Hawaiian Spirulina which is very expensive and thought to be the best but I am so happy to find this is the same color and taste and 1/2 the price. We use in our smoothies every morning to help us to a great start for the day. I ordered the Spirulina in the morning and I swear they had a truck waiting at the dock for my order. Within 1 hour I received an e-mail saying my order had been shipped. Will order 5 more Kilos tomorrow!! Thank you BS.*

On 8/9/2016 Gary said...

Very good product. I didn't know what to make of the fishy taste description I read before I ordered, but figured out that you can mix this with orange juice and bananas and it tastes really good! My energy level seems to be higher all day.

Order with confidence.*

Organic Spirulina Powder
Great Product! I have been using Organic Spirulina for over 15 years. I mix it with my detox drink every morning. It has a fresh taste compared to other Spirulina I have used in the past. This is my first time buying from Bulk Supplements and will order more products in the future. Highly recommend.*

On 2/16/2016 Hollace said...

Awesome as Always!
Wasn't to sure about this one, as it stated "marine taste" in the description, however, can't notice it if what you put it in is tasty! Saying that, I've put this in my spaghetti and a few other dishes. I'm usually cooking for one so the amount I put in is not that large. I haven't tasted it by itself with just water or juice but plan to. I use this as a supplement as I do some of the other products I've purchased from Bulksupplements. I've not been disappointed. The prices beat out over the counter and I feel a lot better buying from them with the "kosher" and "non-GMO" in writing. Also, when you look at the bottles of supplements on the shelves and read the labels ... So glad I found Bulksupplements!*

Takes a bit to dissolve, but doesn't taste too bad with cranberry juice. *

Great in my smoothie!
I had expected this to taste pretty marine like in my smoothie but it did not at all! It blended in very well. It is very fine powder so you have to be careful or it will get all over. Very nice product!*
