Both chlorella and spirulina have bioactive compounds that interact with immune signalling, oxidative balance, mitochondrial function, and the gut microbiome. All of these systems are key players involved in everyday inflammation regulation.
Excessive oxidants can activate your immune system, making it harder to maintain balance. The solution to this is to eat more plant-based foods such as algae tablets.
Both spirulina and chlorella are rich sources of antioxidant compounds [1]. These include phycocyanin (richest in spirulina), chlorophyll, lutein, carotenoids, glutathione, and superoxide dismutase.
Phycocyanin is a blue pigment with antioxidant benefits [2]. Studies find that this support is especially helpful during times when your body is under more strain, like during exercise, with pollution exposure, or other daily stressors [3]. Chlorella contains high amounts of chlorophyll and carotenoids, which support your body’s own antioxidant defenses and healthy immune communication [4]. Rather than shutting down inflammation, these compounds help to regulate the immune system, supporting the systems that are active even when we are healthy [5] .
Spirulina and chlorella also provide key immune vitamins and minerals, including zinc, iron, magnesium, and B vitamins [1]. These nutrients are present in their natural forms and balanced ratios from whole foods, so you can enjoy the algae tablets every day without the concern about nutrient imbalances or toxicity.

Most Americans consume more of the inflammatory fats, including saturated fats and omega-6 fats, than ideal. Too much omega-6 can contribute to inflammation. To support healthy body function and balance, you need marine omega-3 in natural form.
Spirulina has about 5–10% fat, most of which are healthy fats, such as marine omega-3, gamma-linolenic acid (GLA), and their derivatives. About 1–2% of spirulina’s dry weight is made up of GLA [6].
GLA is considered a uniquely good omega-6 that’s also found in evening primrose and hemp seeds. As you age, your ability to make GLA decreases [7]. The body uses GLA to make compounds that help support immune balance and build healthy cell membranes. Research finds that spirulina is one of the few natural, non-seed sources of GLA, providing this fat in a form that can be readily used by the body [7].
Each 30-tablet portion of ENERGYbits® can support a balanced intake of good fats with 0.1 mg of DHA, 86.1 mg of ALA, and 75 mg of GLA fatty acids.
Beyond their main role as your cellular energy powerhouse, mitochondria serve as your body's danger detectors, coordinating defense responses when threats arise.
When mitochondria sense danger, they dial down energy production as a protective measure. But here's the catch: struggling mitochondria create harmful oxidants that trigger unnecessary immune responses [8]. This explains why immune activation and oxidative stress accelerate aging while draining your energy over time.
The solution? Supporting your mitochondria both nutritionally and energetically can help balance inflammation and restore vitality.
Spirulina offers comprehensive mitochondrial support that goes far beyond nutrition. Spirulina's unique polysaccharide complex can jumpstart struggling mitochondria by restoring the cell’s own antioxidant enzyme production [9]. A cell study suggests that spirulina may help mammalian cells harness energy from light [10].
Phycocyanin in spirulina activates pathways that help produce more healthy mitochondria and support optimal mitochondria function [11]. This can translate to better insulin sensitivity, exercise recovery, and healthier cells [12].
These benefits make ENERGYbits® one of the most powerful foods for your mitochondria. You can feel the difference just by chewing a few tablets [13]. The cellular optimization helps your body maintain its natural inflammatory balance, supporting vibrant aging and building lasting resilience from within [9].

Your gut houses over 80% of your immune cells, which interact very closely with your gut flora. Collectively, these microbes are almost like another organ that manages how well your immune system works and when to shut off [14]. Suboptimal microbes can prevail if you haven’t been feeding these microbes well, such as eating too little fibers and polyphenols, and too much of the wrong fats.
As foods, algae tablets provide unique combinations of dietary fibers, polyphenols, and antioxidants that fuel good gut microbes. In both animals and humans, consuming spirulina and chlorella consistently improves the microbiome composition and metabolic outputs [1]. Both spirulina and chlorella feed specific microbiome activities that help immune-balancing signals such as short-chain fatty acids [15],[16].
In one randomized, double-blind, placebo-controlled trial of 40 subjects, consuming chlorella for 4 weeks increased the production of helpful compounds, especially in those whose gut bacteria were less active to begin with. More simply, chlorella seems to work with your existing gut microbiome, suggesting that the benefits depend on the individual [16].
More importantly, even if you’re eating an imperfect diet and sometimes overindulge, chlorella can protect your microbiome. Rodent studies have consistently confirmed that animals that ate a high-fat diet along with chlorella maintain a healthier gut microbiome, along with better metabolic health than those that ate high-fat diets alone [17], [16].

Over 5,000 studies and decades of research have unequivocally confirmed the safety and benefits of spirulina and chlorella. These include hundreds of clinical studies and 12 meta-analyses, which are the highest level of evidence. Here are the pertinent ones.
In a systematic review and meta-analysis of 7 trials with 283 subjects, researchers found that spirulina intake was associated with lower levels of C-reactive protein (CRP), a blood marker for inflammation [18]. While the size of the effect varied between studies, the overall pattern suggests that spirulina is a powerful support for balanced inflammatory response [18].
Another large systematic review of 13 studies with 267 participants found spirulina may help support the body’s antioxidant defenses during endurance exercise and improve exercise tolerance at moderate intensities, especially in people who may not get enough antioxidants from their diet [2]. Dosages ranged from 1–6 grams/day, with interventions lasting between 3–8 weeks [2].
Additional studies also support spirulina and chlorella intake as a means to support metabolic signaling associated with body weight regulation, fat metabolism, and glucose balance [3], [1].
Research in healthy adults has shown that daily chlorella supplementation for eight weeks supported normal immune communication. In this randomized, double-blind, placebo-controlled trial, those who took chlorella showed increased activity of natural killer (NK) cells, part of the body’s everyday immune surveillance system, along with healthy shifts in immune signaling molecules that help immune cells communicate and coordinate their responses. This was after 8 weeks of taking 5 grams (20 tablets) per day. These changes appeared to work together, suggesting that chlorella may help the immune system stay responsive and well-regulated rather than over- or under-active [4].
In rugby players, spirulina supplementation of 5.7 g/day for seven weeks was linked to smaller increases in blood markers associated with exercise-related oxidative stress, inflammation, and muscle strain after intense workouts, compared with placebo [19]. It also appeared to help these markers return to normal more quickly, suggesting spirulina may support recovery from strenuous training, particularly in athletes with high training loads [19].
Chlorella and spirulina are nutrient-dense functional foods that support the body’s natural inflammation management systems, such as antioxidant responses, immune communication, mitochondrial function, and gut microbiome balance. When sourced from high-quality, contaminant-tested products such as ENERGYbits®, they offer an effortless food-forward way to help maintain balance in the context of modern diet, lifestyle, and environment.
