Q&A

Greespi is a functional food.

Greespi is an innovative product made from freshly collected and cryo-stabilized microalgae biomass called Arthrospira. We cultivate it following a unique in-house technology in a closed bioreactor system that ensures laboratory purity, safety and permanent high quality.

• Fast and deep freezing technology has been implemented to preserve the benefits of valuable microalgae components.

Greespi is a highly concentrated food product.

You can find all the essential amino acids, important minerals such as iron, calcium, magnesium and potassium, which support the cardiovascular system, strengthen bones and improve metabolism. It is also a source of B-grouo vitamins (B1, B2, B3, B6, B12), which support energy metabolism, nervous system and skin health.

Greespi is a highly nutritious food as its cell membrane consists of polysaccharides that are easily degraded in the human body, so the product is absorbed very quickly.

• This ensures high bioavailability of all the necessary substances, i.e. the body's ability to absorb them.

Nutrition quality strongly affects human health. 

Greespi is a delicate product that causes no irritation to the GI tract. We strongly recommend consuming Greespi to people facing dietary restrictions or digestive problems. Vitamins and minerals in Greespi are absorbed even with internal organ disorders, making this product extremely beneficial.

The best way to enjoy Greespi:

1. Take the desired number of servings out of the freezer and defrost them for 1-2 minutes in a glass of slightly warm water.

2. Open the sachet and pour its contents into a clean glass.

3. Add 100-200 g of comfortably warm drinking water (do not use hot or boiling water).

• The best way to consume is on an empty stomach, since the product improves gastric mucosa health.

• You may notice a slight odor or protein flavor if Greespi is not consumed within half an hour after defrosting. This condition is absolutely normal, as the product is as fresh as possible and contains no preservatives.

• Defrost the product right before consumption.

The recommended amount:

• Adults - 2 servings per day.

• Children - 1 serving per day.

• Over time, you can gradually increase to 5-6 servings per day, especially when recovering from illness, viral colds or flu. Check out the instructions here.

Once defrosted, consume Greespi immediately. If you leave Greespi sachets defrosted for a long time (more than 3 hours), the product may lose its original properties. In such a case, we do not recommend consuming Greespi. The deterioration process will start after 3 hours of exposure to room temperature.

Greespi does not interact with drugs, although we advise you to consult your physician or pediatrician before consuming the product in case you are currently on multiple medications. Doing so will ensure maximum safety for your health.

• Latest research confirms the positive impact of Greespi on the overall health of people undergoing or recovering from chemotherapy. If you are searching for natural supportive products to speed up your recovery, you can consult your doctor. Contact us if you need more information about the product.

Greespi is a product containing a complex of natural substances such as vitamins, minerals, omega-3 acids, antioxidants and amino acids, all of which are combined to ensure better absorption and maximum benefits for the body.

• Unlike man-made vitamins, which often contain only individual active ingredients, Greespi is a holistic natural product without preservatives, sugars, anti-caking compounds and other artificial additives. Greespi is not subjected to heat treatment (heating, drying), so the high-value protein in the composition retains its natural structure and high bioavailability.

• When ordering Greespi, you get a completely pure, fresh and effective functional food product of completely transparent origin and all the required certifications. 

Greespi is composed of microalgae Arthrospira, which are highly potent and biologically active organisms that can synthesize beneficial substances for the human body. Greespi does so thanks to the photosynthesis process: using the energy of light, they convert inorganic substances (carbon dioxide, water, minerals) into organic compounds.

Non-organic substances mean that they do not contain carbon as organic compounds, such as carbon dioxide and water.

Organic substances are carbon-containing compounds that are the basis for life, such as proteins, fats, carbohydrates, and vitamins and minerals.

Greespi uses light to create complex organic molecules from simple substances that are beneficial to the human body. 

There are several key elements among the compounds synthesized in the course of photosynthesis:

• Chlorophyll is a pigment that allows algae to absorb light and use it for photosynthesis. Chlorophyll exerts antioxidant properties and protects cells from the harmful effects of free radicals.

• Phycocyanin is also a pigment known to assist algae in photosynthesis and exhibit strong antioxidant and anti-inflammatory properties.

• Gamma-linolenic acid (GLA) is a polyunsaturated fatty acid that helps reduce inflammation and supports cardiovascular and skin health.

• Omega-3 fatty acids are important for brain, heart and joint health.

• Vitamins (e.g., groups B, C, E) contribute to the normalization of metabolism, support immunity and have antioxidant properties.

These elements are essential for the body's functioning because:

• Antioxidant properties (chlorophyll, phycocyanin, vitamins) help fight oxidative processes in the body that can cause the development of various diseases, including cardiovascular and neurological diseases, and accelerate aging.

• Omega-3 fatty acids improve brain and heart function, reduce inflammation and promote joint health.

• Gamma-linolenic acid supports skin health, lowers cholesterol and promotes normalization of immune system functions.

These organic compounds are highly bioavailable and biologically active, but they are extremely sensitive to external factors such as temperature, oxygen and light:

• Heat processing, especially when it occurs at high temperatures, destroys nutrients, including vitamins and other antioxidants, which significantly reduces effectiveness of the product.

• Upon contact with oxygen, the oxidation of omega-3 fatty acids leads to a loss of their properties, making these components less valuable for the body.

Freezing is one of the most effective methods of preserving the nutritional properties of products. This process stops oxidative and degradative reactions, which helps to preserve all nutrients and biologically active substances without the need to add preservatives or other chemical compounds. Freezing allows Greespi to bring benefits to the body and preserve its “nutritional purity”.

Functional foods include products that not only provide the body with certain substances, but also offer positive health benefits, helping to prevent diseases and maintain optimal functioning of organs and systems.

Why does Greespi stand for functional food? Greespi is based on microalgae Arthrospira cultivated within specific bioreactors protected from environmental contaminants. It is a biologically active product offering numerous therapeutic properties. Thanks to its unique complex of nutrients, Greespi helps to:

• Boost the immune system thanks to high levels of natural antioxidants (phycocyanin, chlorophyll, beta-carotene), which reduce inflammation and oxidative stress.

• Support for the cardiovascular system due to essential fatty acids, in particular gamma-linolenic acid (GLA), which regulates cholesterol levels.

• Body detoxification, as bioactive peptides and polysaccharides bind heavy metals and toxins, contributing to their elimination.

• Improve intestinal health due to the high bioavailability of proteins and polysaccharides that stimulate the growth of beneficial microflora.

• Preservation of energy and endurance thanks to easily digestible protein and B vitamins, which are crucial for metabolism.

We recommend taking Greespi in the morning on an empty stomach with clean drinking water to activate metabolism at the beginning of the day. 

• Such a ritual will become a great habit for people who have symptoms of gastrointestinal disorders and are forced to choose dietary products for breakfast.

Nutritionists have proven the benefits of protein foods for breakfast. You do not need to prepare complex meals and spend time on it, and you do not have to worry about extra calories. It is recommended that you wait 15-20 minutes after taking Greespi before eating another meal to maximize the absorption of nutrients and biologically active substances.

Greespi's purity and the absence of harmful substances such as GMOs, chemical additives (synthetic colors, preservatives, antibiotics), heavy metals, food allergens are critical aspects that make it safe and healthy.

1. GMOs-free

Foods containing genetically modified organisms (GMOs) can cause unpredictable consequences for health. Although many of these products have been tested for safety, their long-term effects on the human body and the environment are still subject to further research. The natural non-GMO composition ensures that the product preserves its genetic integrity and does not pose any risks associated with artificial genetic changes.

2. No chemical additives and synthetic dyes

Chemical additives and synthetic dyes are used to improve the taste, color, and shelf life of foods. Still, many of these ingredients can be allergenic or toxic, causing gastrointestinal irritation, allergic reactions, or affecting the hormonal system in a negative way. Being free of such substances Greespi causes no such side effects and is much safer to consume.

3. No preservatives or antibiotics

Using preservatives and antibiotics in food can cause various health problems, including the development of antibiotic resistance and disruption of the gut microbiota. Greespi does not contain such substances, which helps to maintain a healthy intestinal microbiota and minimize the risks associated with antibiotic resistance.

4. No heavy metals

Heavy metals (e.g., lead, mercury, cadmium) are toxic to the body. They tend to accumulate in tissues and cause serious diseases of the kidneys, nervous and cardiovascular systems. They enter the food supply through water or soil contamination. Since Greespi is cultivated in a closed bioreactor system, this eliminates a chance of heavy metals getting into the product, ensuring its purity and safety.

5. No pesticides and other harmful chemicals

When pesticides are used in agriculture, products can contain toxic residues that can be ingested and negatively impact the environment. Greespi is cultivated under controlled conditions, where the use of pesticides is excluded, which allows us to obtain a product without harmful toxins.

6. No common food allergens

Milk, flour based products (gluten), soy or peanuts are commonly associated with allergic reactions in humans. Greespi does not contain these common allergens, making it safe for people with various dietary restrictions or allergies.

Greespi can be given to children from 6 years of age, but for younger children we recommend using Greespi after consultation with a pediatrician.

• Daily nutrition supplemented with Greespi is especially necessary for children who are overweight, have vitamin and mineral deficiencies, do not consume vegetables in the proper amount, and are actively involved in sports.

• 1 serving of Greespi per day is enough for children aged 6 and older to benefit from physical and cognitive development. Detailed consumption recommendations are available here.
