Spiralyne spirulina tablets can help maintain a good level of personal wellbeing; with a variety of powerful antioxidants, vitamins and minerals that help you achieve optimum nutrition to keep you feeling great and healthy. Spiralyne spirulina tablets can enhance your body’s immunity against viruses.

Spiralyne spirulina tablets contain powerful antioxidants including; C-phycocyanin1, chlorophyll, zeaxanthin and beta carotene. The human brain is uniquely vulnerable to oxidative injury. Antioxidants can inhibit the oxidation of molecules which can create free radicals. Free radicals cause oxidative damage. Antioxidants are frequently used to treat forms of brain injury2.

• Spirulina contains C-phycocyanin; a powerful antioxidant found only in spirulina and other blue-green microalgae. C-phycocyanin has significant immune enhancing and anti-viral properties. Results from research on C-phycocyanin indicate an increase in resistance to infectious diseases3.


• Zeaxanthin can protect eyes as they age; people with low levels of lutein and zeaxanthin in their macular (eye) are more likely to develop macular disease4.

Beta carotene can be converted to vitamin A5, which is necessary for normal skin6, normal vision7 and for the immune system8.

Spirulina can help your body’s immune system; the calcium spirulan, a compound contained in spirulina, has been found to be very effective against numerous viruses910. A Japanese study found that those taking spirulina showed a significant improvement in immune markers11.

Spirlayne spirulina tablets contain Vitamin B12. Vitamin B12 contributes to normal energy production.

Spiralyne spirulina tablets can act as a natural energy boost to combat fatigue and can help with mental concentration.

Spirulina is the richest natural wholefood source of complete protein (containing all the essential amino acids) in the world and because spirulina has no hard cell walls, it is much easier to digest than other plant foods.

High-protein foods like spirulina are known to increase energy1234.

A study5 (Kalafati M, et al.) published by the official journal of the American College of Sports Medicine, Medicine & Science in Sports & Exercise showed that spirulina induced a significant increase in exercise performance and fat oxidation. In the study, nine moderately trained males took part in a double-blind, placebo-controlled, counterbalanced study. Each subject received 6 grams of spirulina or 6 grams placebo for 4 weeks. Each subject ran on a treadmill at an intensity of 70-75% of their VO2max for 2 hours and then at 95% VO2max to exhaustion. Time to exhaustion was significantly longer after spirulina supplementation; 2.05 minutes and 2.7 minutes with spirulina supplementation (above).

Ingestion of spirulina increased fat oxidation rate by 10.9% during the 2 hour run compared with the placebo trial (left). The antioxidant properties of spirulina may have resulted in increased fat oxidation, which then may have resulted in an increased exercise performance.

Spiralyne spirulina tablets contain powerful antioxidants. Antioxidants can inhibit the oxidation of other molecules, which is important because oxidation reactions can produce free radicals. And free radicals can cause oxidative stress and damage to DNA, RNA and cell structures.

When you exercise, your oxygen consumption increases more than 10 times1. Consequently, there is a significant increase in the production of oxidants that can damage cell structures and can contribute to muscular fatigue. Taking spirulina can increase the amount of intense exercise you can do and it may reduce the amount of muscle damage23thanks to the variety of antioxidants in spirulina.

Spirulina has cardiovascular benefits; it contains the rare essential fatty acid, Gamma-linolenic acid (GLA), which promotes good health. According to a clinical trial in Korea, essential fatty acids like Gamma linolenic acid (GLA) can prevent cholesterol from concentrating in the body.

Spirulina can also reduce bad cholesterol. In a study where 15 male volunteers took 4.2 grams of spirulina per day showed a statistically significant reduction of LDL (bad cholesterol) with no significant change in HDL (good cholesterol). Researchers also measured a significant decrease in the atherogenic effect, a measure of fat desposition in arteries4.

Spirulina and C-phycocyanin can have a protective and preventative effect on heart attacks5 6 7. Studies have shown spirulina and C-phycoyanin can significantly protect from cardiotoxic effects (studies based on mice)8.

Spiralyne spirulina tablets can safely help improve endurance levels.


Amino acids can play an important role in exercise, especially the branched-chain amino acids; valine, isoleucine and leucine. The branched-chain amino acids are unique because they are not metabolized in the liver but in the muscle instead, hence the name, ‘muscle aminos’.

Branched-chain amino acids are important as they help muscle under intense training. In an experiment using swimmers, one group was given branched-chain amino acids and the other a placebo. The branched-chain amino acid group experienced less muscle breakdown after intense exercise9. Studies show that taking essential amino acids, including branched-chain amino acids, before exercise triggers anabolic processes – the increased blood flow you get from training increases the amino acid entry into muscle.

Branched-chain amino acids can lessen muscle damage during exercise and block what is called delayed-onset muscle soreness following intense training10. Sixteen women and 14 men took five grams of branched-chain amino acids before doing seven sets of 20-rep squats, resting two minutes between sets. Some of the subjects got a placebo. Those who took the branched-chain amino acids had significantly less soreness than the placebo group; the results were more significant in the male subjects. The researchers think that the results may be a combination the branched-chain amino acids’ decreasing muscle breakdown and leucine’s stimulation of muscle protein synthesis (anabolism).

Spiralyne spirulina tablets contain all the essential amino acids (including branched-chain amino acids).

Spiralyne spirulina tablets help brain performance. Spirulina contains phenylalanine that is an essential amino acid that contributes to the normal function of the neurons and brain.


Phenylalanine is a precursor of norepinephrine, which is a neurotransmitter.

Neurotransmitters help with mental concentration and memory. Good mental concentration and memory are helpful during stressful times such as exam periods where acute performance is required.

Spirulina can protect the brain1 and when compared to blueberries, spirulina reduced brain damage by ischemia by 70% where blueberries reduced the damage by 30%.

Spiralyne spirulina tablets contain vitamin B12. Vitamin B12 is necessary for the normal structure and function of the neurological system2 and blood formation.

Spiralyne spirulina tablets help maintain healthy skin3, good vision4 and prevent hair discolouration5. The vitamin A (present in Spiralyne spirulina tablets) is necessary for normal skin and normal vision. Copper (in Spiralyne spirulina tablets) is necessary for the normal colouration of hair.
