Spirulina, the green gold from the lake, is among the most nutrient-rich foods our planet has produced. This ancient microalga thrives in highly alkaline waters and has captivated diverse cultures for millennia. Even the Aztecs harvested this precious alga from Mexico's Lake Texcoco and valued it as a energizing food. For a long time, this knowledge remained largely unknown. Almost forgotten, but now more and more people are remembering the miracle algae and using its exceptional vital substance profile to naturally nourish and strengthen their own body (i.e., the entire cellular energy system).

The energy of the ancient wonder algae

Fresh juices and fruit as a source of natural vital substances Spirulina has existed on our planet for approximately three billion years, making it one of the oldest life forms. This tiny blue-green alga played a crucial role in enriching Earth's atmosphere with oxygen and, consequently, carries within it a primal information of life that is virtually unmatched by any other food. Its very name reveals its unique character, as spirulina translates to "little spiral" (the algae grows in fine, spiral-shaped coils). The spiral, in turn, is a primal form of creation that we encounter everywhere in nature, be it in galaxies, shells, fern tips, or even in our DNA. Those who consume spirulina therefore connect with one of the most primal frequencies of life and provide their bodies with a food that has remained virtually unchanged since time immemorial. For this reason, the algae is often referred to as primal food, a gift from the very beginning of our world.

The ingredients of spirulina algae (a true cornucopia of vital substances)

Hardly any other food combines so many high-quality nutrients in such a small space, which is why spirulina is quite rightly called a superfood. More than 100 different vital substances work together in this tiny algae, complementing each other's effects. I've listed the most important ones for you here:

  • Phycocyanin: The blue pigment is the most characteristic active ingredient of blue-green algae and an extremely strong antioxidant that protects our cells from free radicals and at the same time supports the formation of healthy blood cells.
  • Chlorophyll: Spirulina contains about ten times more chlorophyll than conventional garden vegetables. The green plant pigment is structurally similar to our red blood pigment (hemoglobin), has a blood-purifying effect, and supports the formation of red blood cells.
  • High-quality protein: The algae consists of approximately 60 percent high-quality proteins including all essential amino acids, which makes it particularly valuable for people with a plant-based diet.
  • Beta-carotene: Provitamin A is found in spirulina at a concentration about fourteen times higher than in carrots and supports our eyesight, skin and mucous membranes.
  • B vitamins and vitamin E: Vitamins B1, B2, B3, B5 and B6 nourish our nervous system and energy metabolism, while vitamin E further enhances cell protection.
  • Gamma-linolenic acid: This rare fatty acid is otherwise found primarily in breast milk, which is why spirulina is affectionately called the "breast milk of the earth." Together with the omega-3 and omega-6 fatty acids it contains, it supports our cardiovascular system.
  • Minerals and trace elements: Magnesium, iron, calcium, potassium, zinc, chromium, iodine, selenium and manganese are present in a natural, optimally balanced ratio.

The effects on our organism

Colorful vital nutrient juices as part of a natural diet Due to its concentrated abundance of vital nutrients, spirulina has a revitalizing effect on our entire organism and noticeably raises our energy levels. In traditional medicine and naturopathy, this algae has long been valued for strengthening the immune system, stimulating blood formation, and supporting the body in eliminating toxins (chlorophyll binds heavy metals, among other things). Furthermore, this remarkable algae promotes an alkaline and oxygen-rich cellular environment—an internal environment in which our cells can regenerate and in which the body's self-healing powers can fully unfold. Nobel laureate Otto Warburg recognized in his research how fundamental an oxygen-rich, alkaline cellular environment is for the health of our cells, and this is precisely where spirulina comes into play. Those who regularly consume this algae in combination with a diet rich in alkaline-forming, natural foods are therefore giving their bodies the best possible conditions for maintaining order, vitality, and inner balance (as within, so without). Skin, bone structure, muscles and brain function also benefit from the comprehensive spectrum of nutrients, so that daily intake can truly make a difference on all levels.

Application, dosage and the question of quality

Spirulina is most commonly consumed in tablet form or as a fine powder. A daily amount of about three to five grams has proven effective, although it's advisable to start with a smaller dose and increase it gradually so that the body can gently adjust to the nutrient-rich food. The powder can be easily stirred into green smoothies or freshly squeezed juices, while tablets are best taken with plenty of water. If you regularly take medication or are unsure about anything, simply consult a doctor or naturopath you trust. Furthermore, the quality of the product is crucial: many inexpensive preparations are enriched with unnecessary fillers and additives or come from contaminated aquaculture facilities, which completely defeats the purpose of taking spirulina. When buying, therefore, be sure to look for certified organic quality from controlled aquaculture and ensure that the robust cell walls of the algae have been gently broken down, as this is the only way our bodies can fully absorb the valuable nutrients.

Closing words

Spirulina is a true gift of nature, an ancient life form that provides us with a wealth of vital nutrients and reminds us that nature has long provided for our well-being. Those who give their bodies such natural nourishment daily not only nourish their cells but also strengthen the foundation upon which health, clarity, and joy of life can flourish. In this context, it's also worth taking a look at... The nutrient-rich magic root turmericwhich can enrich our health in a very similar way. Everything always begins within us, in our minds; never forget that. With that in mind, stay healthy, happy, and live a life in harmony. 🙂
