In the endurance sport community, spirulina has become a trendy addition to the postworkoutfor its antioxidant and anti-inflammatory properties. Blue green algae, or “spirulina,” was a common item within the health food industry long before it became a “superfood” for its purported health and nutrition benefits.
Here, we’ll dive into to what spirulina is and whether there’s enough evidence to back up the claims behind algae supplements for cyclists.
Dr. Fauci Says Do This Now to Avoid Delta
Looking out for your safety and that of your family, Dr. Anthony Fauci has issued guidance about what to do to avoid Delta.
What are the nutritional benefits of spirulina?
Spirulina is a cyanobacteria derived from blue green algae and then dried to be used in pill or powder form. (Sometimes spirulina is combined with a plant-based protein powder in small amounts).
Spirulina supplements claim to be rich inand micronutrients—such as , calcium, , and —and boast antioxidant and anti-inflammatory properties, but you would need to take a lot more than the amount being used in research to reap the nutrient benefits.
For reference, 1 tablespoon (or 7 grams) of spirulina is about the amount used in most studies. This small amount of spirulina contains the following:
- 20 calories
- 1.7 g carbs
- 4 g protein
- 95 mg potassium
- 74 mg sodium
- 8.5 mg calcium
- 14 mg magnesium
- 2 mg iron
Perhaps overlooked, spirulina is also high inand beta carotene.

As with all supplements, a sport science researcher at Kingston University in London suggests “checking the ingredient label and whether the supplement is independently batch tested for purity and quality.”
Why is spirulina good for you in general?
The anti-inflammatory properties are primarily associated with phycocyanobilin, the blue-green pigment found in spirulina, which containing antioxidant properties. This rich antioxidant may help decreasein your body and help with exercise . However, the use of high antioxidant or anti-inflammatory products during the base phase of training use is questionable as it may interfere with training adaptations, according to sports dietitian . That’s because, during the base phase of training, the inflammatory response is important for training adaptations to occur. Thus, the use of high antioxidant products may be better utilized during the racing season for rapid recovery purposes.
How To Reverse Grey Hair, Study Finds
The study, published June 22 in eLife, found that stress-induced hair graying can be restored if the stress is eliminated.The study, published in eLife, found that stress-induced hair graying can be restored if the stress is eliminated, according to researchers at Columbia University Vagelos College of Physicians and Surgeons. The study's senior author Martin Picard, Ph.D., associate professor of behavioral medicine (in psychiatry and neurology) at Columbia University Vagelos College of Physicians and Surgeons, explains that the study offers major insight into aging.

Can spirulina help with cycling performance specifically?
While initial studies have examined health benefits of spirulina—for instance, reductions in risk for factors forand improved —more recent work has examined the potential benefits for exercise performance.
A recent study published in the journal Applied Physiology Nutrition and Metabolism examined spirulina supplementation (6 grams per day) for 21 days on various cycling intensities. The study authors found a significantly lower heart rate and blood lactate levels during low intensity cycling sessions after supplementation with spirulina.
“Increases in hemoglobin and improvements in power output were also observed after supplementation with spirulina,” says Gurney, who was the lead author of the study.
While these results seem promising, Gurney cautions it’s important to remember that this area is still very new and in its early stages. However, there may be a potential reason for these observed improvements.
RSV vs. COVID-19: Symptoms to Watch For, According to Doctors
Cases of both contagious viruses are on the rise right now. The Centers for Disease Control and Prevention (CDC) issued a health advisory in June, warning doctors about an increase in RSV cases across the southern US. "Due to this increased activity, CDC encourages broader testing for RSV among patients presenting with acute respiratory illness who test negative for SARS-CoV-2, the virus that causes COVID-19," the advisory said. It also noted that RSV can cause "severe disease" in young children and the elderly. © Provided by Health.
“Although speculative, the high iron content and bioavailability [a measure of how much a substance is able to access your body’s circulation and reach the target area] of spirulina may explain the increases in hemoglobin found in these studies,” he says.
It’s no doubt that hemoglobin—the protein that transports oxygen from the lungs to the muscles during—is important for endurance performance.
“If there are significant changes to hematological markers, such as hemoglobin, supplementation should be advised under supervision by an R.D.N. or physician to ensure safety and avoidance of any interactions or contraindications [situations where a drug or procedure should not be used because it may be harmful to the person],” says Kumar.
Is there an optimal dosage that provides benefits?
The majority of the studies examining athletic performance have used 6 grams of spirulina per day, and studies examining health benefits have ranged from 2 to 8 grams per day. More research is needed to determine the optimal dosage, how long the supplement should be taken, and timing of delivery of spirulina.
“The trend at the moment seems to suggest that a loading period—rather than taking it quickly before exercise—is required before any benefits are seen,” Gurney says. “However, our previous work demonstrated that loading with 6 grams per day of spirulina for one week was beneficial for arm cranking [in the study]—or[in general]—while the more recent study used a loading protocol of 6 grams per day of spirulina for three weeks.”
The bottom line
Before you buy into the hype, more research is needed to determine how and whether spirulina improves exercise performance in cyclists.
“While it’s tempting to rely on ‘superfoods’ like spirulina for performance benefits, we don’t really have enough information yet to recommend supplementation,” says Kumar.
However, if you are set on giving spirulina a try in your smoothie bowl, be sure to choose a product that is third-party tested.
