How many kcal is one tub?

One tub contains 19 kcal and a lot of nutrients.

How does it taste?

Our spirulina is virtually odorless and tasteless and can therefore easily be used in all kinds of dishes. Some customers find it silky, walnut taste..

Does your spirulina fit into any diet?

Our spirulina is all-natural, 100% vegan & vegetarian, gluten-free, dairy-free, soy-free, GMO-free, halal and kosher, so it fits easily into any diet.

Can I use it every day?

Yes, you can use Simpligreen Spirulina every day, for longer periods in a row. It is a complete food that you can take every day to improve your health. 

How much Spirulina can I take per day?

We recommend one tub per day, so that you will feel the effects after a few days. Taking more than this is certainly allowed. Some athletes take up to five portions a day, but we recommend two a day for this group.

Can I stop immediately after using the product?

Yes, you can stop whenever you want. 

Are there any contraindications? Or when should you not take it?

If you are taking medication that suppresses the immune system or use blood thinners. Spirulina can aggravate autoimmune diseases by boosting the immune system. 

Why is it expensive?

It took 8 years and a lot of money to develop our fresh frozen, raw spirulina. That is why it is (still) expensive.

But it is very concentrated and effective and therefore inexpensive.

Why 3.5 euros for a glass of municipal water with two slices of ginger? Doesn't contain anything.

Are there any side effects to be expected?

You may experience some inconvenience from the detox effect, such as headaches and a heavy head. If so, skip one or two days. Darker urine and more frequent visits to the toilet are also to be expected. 

What is the best way to eat/drink?

It is best to take it as pure as possible. So preferably put it in the blender or mix the spirulina through your food shortly before you eat.

We recommend taking it right at the start of your day. This allows you to make the most of the benefits.

How is Simpligreen's spirulina made?

We grow the spirulina using solar energy and plant-based fertiliser in our natural warm water basins in Israel. From there we harvest the algae every 10 days, filter them, remove the water and then freeze them immediately so that all the nutrients are preserved until they reach you. From 10 kilos of fresh spirulina, we make 1 kilo frozen. With 0% waste and hardly any water consumption. That's it! Of course, we regularly carry out the necessary safety checks to ensure that everything is clean and stays that way.

What exactly is spirulina?

Spirulina is one of the oldest organisms on earth. It is a single-celled, non-toxic blue-green algae, in fact a "plant" without roots, which grows in water. The Latin word for spirulina is arthrospira = small spiral, because under a microscope it does indeed have this shape. Spirulina grows where it is warm and has many hours of sunshine, and Simpligreens pools are therefore in Israel. Its natural function in the water is that of purification, due to the chlorophyll and the phycocyanin that are naturally produced by the sunlight.

Where does the green colour come from?

Spirulina's colourful bio-chemistry has a wide range of health benefits that enhance your body's functional performance. Chlorophyll, the green pigment that gives spirulina its colour, helps regenerate damaged liver cells and remove toxins from your blood and organs. Phycocyanin, the blue pigment found in algae, improves liver function, reduces inflammation and helps the body digest amino acids. And porphyrin, a deep purple pigment, forms the protein-rich haemoglobin that is essential for healthy red blood cells to perform metabolic processes throughout the body.

Why can it help with weight loss?

Consuming our spirulina as part of a balanced diet and active lifestyle can greatly aid weight loss. Our raw, fresh spirulina contains high levels of fast absorbing nutrients and is also low in calories. It is also low in calories, which means that it can help satisfy hunger and reduce the need to eat.

What is in the spirulina of Simpligreen?

Our raw spirulina consists of 74% whole plant protein with 18 amino acids. These play a crucial role in almost all biological functions of the body. Our spirulina contains all 8 essential amino acids that cannot be synthesised by the human body. But it also provides a source for 10 of the 12 non-essential amino acids that are made by our bodies. Amino acids are the essential building blocks in the process of cell renewal in our body. 

Spirulina also contains gamma-linolenic acid (GLA), the important omega-6 essential fatty acid with disease-fighting properties. It is also a great source of vitamins, including vitamin B-1 (thiamine), B-2 (riboflavin), B-3 (nicotinamide), B-6 (pyridoxine), B-9 (folic acid), B-12, vitamin C, vitamin D, vitamin A and vitamin E; as well as a high concentration of vital minerals such as potassium, calcium, chromium, copper, magnesium, manganese, phosphorus, selenium, sodium, zinc and iron.

That requires some explanation. 1 tub of Simpligreen contains 3.2 mg of iron, 18% of your daily requirement. This may sound like less than an iron supplement, but the effect is greater. The key to reducing iron deficiency is bioavailability. Simpligreen is 100% natural and raw and because of its special structure can be absorbed by your body up to 95%. Non-natural iron supplements only reach 10% on average.

Isn't your spirulina toxic like other blue-green algae?

No. Harmful substances occur in products that are cultivated in an uncontrolled environment. Our production facility is ISO, HACCP and BRC certified. In addition, through collaboration with leading academic and private research institutes, we have developed innovative testing tools, not yet common in the industry, to ensure that our spirulina is truly 100% pure.

What is the difference with other proteins?

Our raw spirulina is 74% complete protein, with all essential amino acids in perfect balance. Beef, for example, consists of 22% protein.  Unlike other meat or vegetable protein sources, our spirulina has no hard cell walls (cellulose), making the spirulina protein and amino acids much easier for your body to absorb.

What is the difference Spirulina in dried form?

Most dry spirulina is made using a spray-drying method with hot gas, which converts the spirulina mass into powder. This process degrades the algae molecule and results in reduced nutritional values and enzymes - the latter also causing the notoriously unpleasant smell and taste of spirulina. About 40-50% of the nutritional value is lost about 45 days after it is dried. Some studies suggest that dried spirulina has only 15% of the nutritional value of fresh spirulina.

Is your spirulina certified organic?

Our spirulina is grown under organic conditions in fresh water tanks in a closed, controlled system. It is not exposed to outside pollutants such as industrial waste, air pollution or acid rain, which is often the case in open environments. For dry spirulina animal manure is almost always used. However, only food grown in the ground can currently meet the USDA guidelines for organic classification. Then you also have to pasteurise and irradiate your product, which causes you to lose a lot of product quality. We are currently discussing a better solution that does justice to our product.

How long can I keep it in the freezer?

In a normal freezer like the one at home, you can keep our spirulina for about 8 months.
