Spirulina improves lipid profiles effectively
We explored the impact of Spirulina supplementation on cardiovascular health by analyzing data from randomized controlled trials. Our findings were based on a thorough review that included over a thousand participants across 20 studies.

The results showed that Spirulina effectively reduced levels of bad cholesterol (LDL-C), total cholesterol (TC), and triglycerides (TG), while boosting levels of good cholesterol (HDL-C). Overall, incorporating Spirulina into our diets might be a helpful strategy for improving our lipid profiles and supporting heart health.

Silicon-enriched spirulina aids arteries
We investigated whether silicon-enriched spirulina could help improve cardiovascular health in hypertensive rats. Our three-month study involved both hypertensive and normotensive rats receiving either silicon-enriched spirulina or regular spirulina. We found that the silicon-enriched version significantly lowered blood pressure and improved the structure and function of arteries in hypertensive rats. There was a notable reduction in arterial stiffness, and the composition of the arterial wall showed positive changes. However, regular spirulina did not exhibit any significant benefits.

We explored the effects of spirulina on blood pressure by analyzing randomized controlled trials (RCTs). This systematic review found that spirulina supplementation can significantly lower both systolic and diastolic blood pressure in adults, especially in those with hypertension, overweight individuals, and older adults.

While we observed a reduction in blood pressure levels, the overall quality of the evidence was categorized as moderate due to the limited number of studies and participants.

Future high-quality RCTs are essential to confirm these findings and clarify optimal dosages and intervention durations for clinical use.

Spirulina, HIIT improve cardiovascular health
We examined how Spirulina supplementation combined with high-intensity interval training (HIIT) might improve cardiovascular health in men with obesity. Over 12 weeks, 44 participants engaged in different combinations of HIIT and Spirulina.

Our results showed promising changes, including reduced levels of bad cholesterol and significant decreases in harmful adipokines compared to a control group. While these treatments showcased benefits for body weight and lipid profiles, the findings confirm that Spirulina, paired with exercise, may effectively target metabolic issues associated with obesity.

Spirulina, HIIT show cardiovascular benefits
We assessed how 12 weeks of high-intensity interval training (HIIT) combined with spirulina supplementation impacts key health indicators in men with obesity. By dividing 44 participants into four groups, we observed changes in body composition and blood markers like apolipoproteins.

The results showed that those who took spirulina alongside HIIT had increased levels of Apo-A and decreases in Apo-B and Apo-J. Additionally, this combination improved body fat, BMI, and insulin resistance. Overall, spirulina with HIIT can support effective obesity management and potentially lower cardiovascular disease risk.

Spirulina's potential heart health benefits
We explored how spirulina, a nutrient-rich cyanobacterium, affects risk factors related to cardiovascular disease. The review highlighted that spirulina may help reduce body weight, inflammation, and cholesterol levels while improving insulin sensitivity. Although we noticed beneficial effects, such as lowering triglycerides and increasing good cholesterol, glycated hemoglobin levels remained unaffected. The varying doses and study designs indicate that further research, especially randomized clinical trials, is vital to confirm spirulina's role in managing heart health effectively.
