For people who pay close attention to their diet, this mismatch has become familiar: there’s no shortage of advice, “health” products or information — yet the feeling of inner resource, steady energy and comfortable digestion is still missing.
In parallel, a large global study by the Rome Foundation, published in Gastroenterology, showed that over 40% of adults meet the criteria for at least one disorder of gut–brain interaction (DGBI), significantly impacting quality of life.
In modern health frameworks, these two dimensions are increasingly considered together:
- the quality of nutrition at the level of individual nutrients;
- the state of the gut and microbiome, which ultimately determines whether “the right diet” is translated into effective cellular nourishment.
Why It Rarely Appears as a Clear, Single ProblemA combination of subclinical nutrient inadequacies and functional changes in gut function rarely presents as one clear, isolated symptom.
01- Impact on Quality of Life
Aging does not start with the cells – it begins with imbalance in the gut.
02 - When “Eating Right” Doesn’t Deliver the Expected Results
European data (EURRECA, EFSA, Public Health Nutrition, European Journal of Nutrition) show that even in populations with broad access to food, a substantial proportion of people do not reach the recommended intakes of iron, folate, vitamin D, iodine and other micronutrients.
03 - A New Focus for the Key Questions
Post-meal fatigue, sweet cravings, or difficulty losing weight can indicate reduced metabolic flexibility – the ability of cells to use energy efficiently.

The gut microbiome is not “bacteria in a vacuum”, but an active participant in nutrition. It:
- synthesises part of the B- and K-vitamins;
- influences the solubility and absorption of minerals;
- supports the integrity of the mucosal barrier and the function of transporters in the intestinal epithelium;
- modulates low-grade inflammation, which increases the body’s nutrient demands.
This picture is not limited to people with established medical diagnoses. In the higher-risk group are those who:
- rely on coffee for breakfast and grab random snacks instead of structured meals;
- follow strict restrictive diets (gluten-free, keto, “no carbs”) without a coherent strategy to compensate for lost nutrients;
- live with chronic stress and ongoing sleep deprivation;
have undergone several courses of antibiotics over the past few years.
A modern diet easily provides:
- an excess of refined carbohydrates and ultra-processed foods;
- a steady flow of coffee and snacks instead of complete meals.
At the same time, it can be chronically low in:
- high-quality, complete protein;
- iron, zinc, magnesium, calcium, iodine, selenium;
- B vitamins, provitamin A, vitamin E;
- prebiotic fibres and natural antioxidant compounds.
The contemporary understanding of this problem is based on a simple but fundamental principle:
- You cannot correct nutritional deficiencies while ignoring the state of the gut,
- And you cannot support the microbiome while leaving the diet nutritionally empty.
- Any meaningful solution has to operate along both axes at the same time.
- Increase the Nutritional Density of the Diet
This is not about achieving a “perfect diet”, but about consistently adding foods that provide more than just calories:
- protein with a complete amino acid profile that the body can effectively utilise;
- trace elements (iron, magnesium, zinc, calcium, phosphorus, potassium) in forms the body can actually recruit and use;
- B vitamins, provitamin A and vitamin E in a natural food matrix, not only as isolated synthetic forms;
- antioxidant compounds (carotenoids, chlorophylls, polyphenols) involved in maintaining redox balance.
This is the foundational layer: giving cells the material they need to work with.
- Support the Microbiome and Mucosal Barrier – Not “Break and Reset”
Instead of aggressive detoxes and radical protocols, the modern logic is gentle, consistent support built around:
- Prebiotic fibres and polysaccharides that feed beneficial bacteria;
- Nutrients involved in maintaining epithelial integrity (amino acids, trace minerals, polyunsaturated fatty acids);
- Antioxidant compounds studied in the context of reducing oxidative load on the mucosa.
The goal is not to “cleanse at any cost”, but to create conditions in whichh:
- The gut functions more smoothly and predictably;
- The microbiome has substrates to live on and produce its own metabolites;
- The body is able to use more of what we actually eat.
The rapid-freezing format helps preserve sensitive bioactive compounds, their native activity and redox potential, maintaining the functional value of the product. For the person, this means preserving not only the nutritional content, but also the natural antioxidant component of the food.
In the context of combined microbiome imbalance and nutritional hunger, Greespi can be viewed as a daily serving of whole functional food that acts along three complementary axes: it increases the nutritional density of the diet through native, bioavailable nutrients; provides the microbiome with a specific fermented substrate based on microalgal polysaccharides; and contributes antioxidant support to redox processes at the mucosal level — while maintaining a physiologically gentle profile for the digestive system and suitability for regular, everyday use.
Each Greespi sachet is a concentrated portion of whole functional food with a high content of native protein with a complete amino acid profile and a natural spectrum of micronutrients: minerals (including iron, calcium, magnesium, potassium, zinc), B vitamins (B1, B2, B3, B6), provitamin A (β-carotene) and other antioxidant pigments.
Greespi preserves a unique complex of water-soluble anionic polysaccharides. These are high-molecular-weight carbohydrate chains composed of several types of sugars and charged groups — a structure that differs substantially from the fibre found in vegetables or grains, where cellulose, hemicelluloses and pectins predominate.
Greespi contains a complex of natural antioxidant pigments — phycocyanin, carotenoids and chlorophylls — within a whole-food matrix.
My bloodwork doesn’t show any ‘major’ abnormalities, but ferritin and B vitamins are at the lower end, and I’m constantly tired. Greespi has become a way for me to add a daily nutritional base, instead of building yet another stack of supplements.
After several courses of antibiotics and attempts at ‘perfect’ diets, I realised the issue wasn’t only about calories, but also about my gut. Two portions of Greespi a day give me the sense that I’m supporting both my microbiome and overall nutrient density—without rigid protocols.
I work with a nutritionist, my diet is structured, but bloating and the feeling of deficiency didn’t fully go away. When I added Greespi between meals, I noticed a simple shift: my protein and micronutrient ‘base’ feels at least partially covered, and my gut reacts more calmly.
“We see how the combination of microbiome imbalance and hidden deficiencies has become the norm for millions of people. Greespi was created as a daily nutritional support in this reality – a food-first approach that respects the gut.”
When Greespi is taken on an empty stomach, the first nutritional signal for the gut is a portion of whole functional food — not coffee, sugar or a random snack. This way of starting the day aligns with contemporary nutritional thinking: first — a high-quality signal for the mucosa and microbiome, and only then all the other foods that come throughout the day.
Greespi is a ready-to-use portion of whole functional food in a convenient 20 g frozen sachet.
A mild “green” profile with a fresh, natural note; subtle in water and non-dominant in fruit–vegetable smoothies.
- Suggested intake: 2 sachets per day;
- Consume with cold water or blended into fruit and vegetable smoothies;
- Defrost immediately before use;
- Do not refreeze once thawed;
- Do not heat above 40 °C to preserve bioactivity.
- A Sustained Sense of “Resource” Between Meals
Greespi adds a nutritionally dense portion of whole food to the day, which can be built into breakfast or one of the snack occasions. This creates a tangible “anchor point”: the body receives more structural and regulatory nutrients throughout the day — without relying on heavy meals.
- Fewer Chaotic Snacks, More Structure
Under conditions of nutritional hunger, eating patterns easily become fragmented: random snacks, another coffee, “something sweet” just to get through the day. When there is one stable, nutrient-dense portion in the daily routine, it becomes easier to maintain a basic eating structure and avoid topping up calories with low-nutrient, incidental foods.
- Support During Protocols and Dietary Change
During gut-focused protocols, dietary changes or the exclusion of certain food groups, it is important not to drop protein and micronutrient intake. In such periods, Greespi can serve as a stable nutritional foundation: a whole functional food that helps provide key nutrients while remaining gentle on digestion.
You may recognise yourself if:
- Your diet is formally “correct” (expert recommendations, supplements, “healthy” products), but a stable sense of energy and internal resource is still missing;
- You periodically experience bloating, heaviness or discomfort after meals, while no organic gastrointestinal disease has been identified;
- You have a history of restrictive approaches (keto, low-carb, gluten-free, “no sugar”, etc.), and now you are unsure whether you get enough protein and micronutrients on typical days;
- You have already tried several supplement regimens or digestive “protocols”, but the effect feels partial or is noticeable only while you are actively following the course;
- Your day often looks like this: coffee instead of breakfast, irregular meals, snacks between meetings — the diet is caloric, but not consistently nutrient-dense;
- Despite a “right” approach to nutrition and lifestyle, the condition of your skin, hair, mood and recovery capacity does not fully match the effort you invest.
- Clean Label
No added sweeteners, preservatives, colourants, flavourings, thickeners or other artificial components.
- Free From Common Allergens
Contains no dairy ingredients, gluten, soy, eggs or peanuts — important when there are people with sensitive digestion or common dietary restrictions in a family or team.
- Food, not a Supplement Course
Greespi is a portioned everyday food product, not capsules or powders that need to be taken “as a course” and then discontinued.
- Modern Food-First Approach
The product is designed as a nutrient-dense foundation for the diet that is easy to add into your day without radically changing how you eat — but helping to improve the overall quality of what you eat.
If you have specific allergies or medical conditions, always consider your individual tolerance and follow your healthcare professional’s recommendations.
- Controlled production – closed photobioreactors with aseptic conditions ensure batch-to-batch stability and purity.
- Flash-freezing – freezing at the point of peak freshness preserves cell structure and sensitive nutrients without preservatives.
- ISO 22000, HACCP, SGS – international food safety standards and independent laboratory testing.
- Halal, Kosher, Organic/BIO, Vegan – certified compliance with key dietary and organic requirements.
A rapid freezing process at the point of peak freshness helps preserve the bioactivity of sensitive compounds such as phycocyanin, γ-linolenic acid (GLA), carotenoids and vitamin E.
Research from food science departments (e.g. University of California) has shown that flash-freezing can help retain bioactivity and bioavailability of labile nutrients without the need for preservatives or intensive processing.

- Children with nutritional deficiency
In children with insufficient nutrition, adding microalgae-based products to the baseline diet was associated with improvements in body weight, growth and selected haematological markers (haemoglobin, total protein, albumin) compared with standard nutrition alone.
International Journal of Pediatrics, 2016Microalgae are considered a nutrient-dense component of the diet in vulnerable paediatric groups, where basic food intake does not fully cover protein and micronutrient needs. - At-risk children in school nutrition programmes
BMC Complementary Medicine & Therapies (2024): An 8-week course of microalgae improved antioxidant status and quality of life with no adverse effects reported.
Frontiers in Pediatrics, 2022Under chronically “poor” dietary conditions, microalgae-based products can help support growth and nutritional status in real-world settings, not only within short-term clinical interventions. - Adults with chronic nutritional load
In adults with an increased risk of anaemia and chronic nutritional strain, adding microalgae-based products to the diet was associated with improvements in selected iron-deficiency markers and overall protein status compared with placebo. In separate studies involving adults with functional digestive disorders, intake of such products was associated with reductions in markers of intestinal permeability (zonulin) and improvements in antioxidant status.
Clinical Nutrition ESPEN, 2023; additional clinical studiesIn adults living with chronic “under-fuelling”, microalgae can act as an additional source of nutrients while simultaneously supporting markers related to mucosal barrier integrity and antioxidant defence. - Polysaccharides, the microbiome and systemic mechanisms
Review articles on microalgal polysaccharides show that these biopolymers can act as prebiotics: they are fermented by the gut microbiota into short-chain fatty acids (SCFAs), support the growth of Lactobacillus and Bifidobacterium, and influence microbiome composition and metabolite profiles. Systematic reviews and meta-analyses also describe associations between microalgae consumption and reductions in low-grade inflammatory markers and oxidative stress.
Frontiers in Nutrition, 2021; Journal of Functional Foods, 2024Natural polysaccharides and pigments from microalgae are considered factors that may support the microbiome, gut barrier function and background inflammatory–oxidative processes.
Consistent scientific data indicate that microalgae-based products:
- enhance protein and micronutrient supply in the diet (including iron, other trace elements and B-vitamins) under conditions of nutritional hunger;
- are involved in processes linked to the microbiome, mucosal barrier function and antioxidant protection at the intestinal level.
Greespi does not replicate any of these study protocols and does not claim their specific outcomes.
Our product relies on this scientific context as a rationale for a food-first approach: a daily portion of whole functional food can be one of the elements of nutritional support when nutritional hunger and microbiome imbalance coexist in the same body.
The data above are drawn from independent studies conducted with various microalgae-based products in different formats and populations. They are not a claim of therapeutic properties for any specific product, nor are they equivalent to the clinical effects of Greesp
