What spirulina is
Spirulina is a blue-green microalga, strictly a type of cyanobacterium, in the genus Arthrospira. Under a microscope it forms fine, coiled filaments, which is where the name comes from. It makes its energy from sunlight, and its deep color comes from pigments including phycocyanin, the blue one, and chlorophyll, the green one.
It is sold as a dried powder, pressed tablets or capsule material, and it has a distinct earthy, slightly marine flavor.
Where it comes from
Spirulina thrives in warm, alkaline, mineral-rich waters, and it occurs naturally in lakes in parts of Africa and Central America. Commercial supply today comes mostly from cultivation in shallow ponds and controlled tanks, where the culture is harvested, filtered, washed and dried. Growing conditions, water source and drying method all shape the finished powder.
Traditional background
People around Lake Texcoco in the Aztec world are described as harvesting algae from the water and pressing it into dried cakes, and communities near Lake Chad in Africa have long dried a similar algae into a food called dihe. Both are examples of an everyday food, rather than a modern invention.
It later drew attention as a compact whole food, and it now appears in many nutrition products. For general reference on nutrient ingredients, see the NIH Office of Dietary Supplements fact sheets.
The role it is associated with
Spirulina is associated with antioxidant support, partly because of its pigments, and it is a popular choice for blends that want a plant-based component. In Nervecept® the brand positions the three-part botanical blend for antioxidant support, while the specific nerve-related roles belong to the vitamins and magnesium.
It shares the blend with Horsetail and Fo-Ti.
Where it sits in Nervecept®
Spirulina is the third name in the botanical blend inside each once-daily vegetable capsule. The individual amount is not published, so no number is available for spirulina alone. The formula is stimulant-free, and the brand lists a bottle as a 30-day supply of 30 capsules.
See the whole formula on the Nervecept® ingredients overview, or read horsetail, fo-ti and spirulina: the botanical blend explained for the full picture. Prefer a quick tour of the others? Start with Vitamin B12 or Magnesium.
Reading it on your bottle
On the Supplement Facts panel, Spirulina appears as one name inside the botanical blend line, listed with Horsetail and Fo-Ti. The label gives no separate figure for it, so what you read is the name and its place in the blend. Our walk-through, how to read a supplement facts label, shows each step.
Follow the serving directions on the bottle label: one capsule daily with a full 8 oz glass of water, ideally 20 to 30 minutes before a meal. Ready when you are: See the Nervecept® kits. Every kit comes with a 60-day money-back guarantee counted from the purchase date; confirm details at checkout.
