NSI Spirulina Natural Whole Food Algae -- 1,000 mg - 360 Tablets

NSI Spirulina Natural Whole Food Algae -- 1,000 mg - 360 Tablets

Nutrition-packed, all-natural whole food source! How Does NSI® Spirulina Natural Whole Food Algae Work? Spirulina is a type of blue-green algae whole food. It contains all eight essential amino acids, making it a complete protein, plus B-complex vitamins, beta carotene, vitamin E, carotenoids, manganese, zinc, copper, iron, gamma linoleic acid (GLA) and calcium. NSI® Spirulina Natural Whole Food Algae comes in convenient, easy-to-swallow tablets delivering 1,000 mg of all-natural, nutrient-dense spirulina in just two tablets. NSI® Spirulina Natural Whole Food Algae is better because it:. Is a complete all-vegetable protein source—ideal for vegetarians or athletes! Contains no artificial ingredients, additives or preservatives.  . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"This product used to be good when the pills were capsule shaped and came with nice white cotton to buffer them.

The last time I bought this the quality went waaaaaay down. They are now round--but not coated. Half the spirulina was at the bottom of the container, and one little wad of cotton was mixed in. Really bad."

"I take this supplement because I don't get all the vegetables and fruits I need every day. So I needed to supplement my diet. I feel a little better. I will keep buying it for the value as compared to other similar supplements. I am also a smoker so I need all the supplementation I can get."

"This is the micro-algae that is known to be the origin of plant based stem cells. They can multiply inside body into beneficial microorganisms. This is the ultimate multi-vitamin of life. I think it detoxifies your bowels, controls appetite, an excellent source of every required mineral needed by body. I even think this keeps your hair from growing gray and keeps skin youthful if you take it on daily basis. Only my opinion! But I've noticed big difference. Best to take at night with empty stomach or 2 hrs after eating. It can give you nauseating feeling when taken with food."

"Whenever I'm feeling down, I take the recommended dosage and I find myself back up and tackling the day again. Now I take a lot of other supplements too, but this one definitely helps throughout the day. That requirement may change as I add resveratrol! This product was pretty messy, I had a lot of green powder to clean up around my desk and clothing from time to time. I'm trying the other brand next, search for that review in the near future (3000mg version)!"

"I read great reviews about spirulina from natural health expert. Since spirulina contains broad range of vitamins, minerals, fatty acids and protein -I stopped taking all other supplements except this one. It works wonderful for me. I have energy, it gave me great clear skin, my brain function and concentration increased, my anemia and fatigues have vanished- so far. I feel healthy. I take a handful of spirulina each day-- about 10-20 tabs. NSI brand works great except tabs break too easy- don't like that..."

"I saw Spirulina algae mentioned as an excellent source of protein on a documentary and since I don't get that much protein in my diet, decided to try this. It hasn't been that long, only a couple of weeks, but it so easy now to take as a vitamin supplement. The tablets are virtually tasteless and very small so they are easy to swallow. I rarely have time for breakfast so I most days, this is it."

"I am a 41 years young and started to feel a loss in energy and began reading up on the health benefits of Spirulina. Every article I read showed positive benefits and I finally decided to place an order. I can say after taking the daily recommended dose of Spirulina for for the past several months that my energy level is up, I am able to work longer without being worn out and my concentration level is sharper.
Vitacost has a great price and they were fast to deliver. I gave only 4 stars on the quality as quite a number of the tablets were broken. Other than that is is a great product!"

"I am a herbal researcher and am pleased with the no nonsense way that Vitacost does their business.
I know that the chorophyll content in the Spirullina is good. I just started to take the supplement and am training hard for an epic run across the rockies. The Spirullina will be vital in my recovery"

"I've been taking spirulina for about three months. I absolutely notice a difference in energy and mind clarity. It is subtle. But, well worth cost and effort! I have tried the powder and found it to be tough to dissolve and generally tasted bad. I find the pills to be just as effective, no real taste, and much more convenient than the powder."

"I have been a vegetarian for only 2 months now. I've changed my diet because of illnesses and other reasons. I read that Spirulina is good for vegetarians and athletes, so I decided to give it a try. I've noticed that I get up in the morning (6 am) quickly. With no aches and pains like I used to. I feel ready to face the world."

"This product works for me, gives me more energy than I have had for years.
I am a 62yr old woman, and have been taking Spirulina for just under a month, in that time I have decorated three rooms in my house, and am planning on doing more DIY.
I feel so much better, and more positive about Life in general.
I would thoroughly recommend Spirulina and have done so to all my friends, here in Scotland."
