Living with HIV often comes with additional health challenges beyond managing the virus itself. One common concern is insulin resistance (IR), a condition where the body’s cells become less responsive to insulin, increasing the risk of developing type 2 diabetes. Both HIV infection and long-term antiretroviral therapy (HAART) can contribute to these metabolic changes.
A recent pilot study explored whether two affordable nutritional supplements—Spirulina platensis and soybean—could help improve insulin sensitivity in HIV-infected individuals.

The Study at a Glance
Researchers at the National Obesity Centre of Cameroon conducted a randomized clinical study involving 33 HIV-positive patients who had insulin resistance.
Participants were randomly assigned to receive either:
19 grams of Spirulina platensis daily (17 participants)
19 grams of soybean daily (16 participants)
The study lasted eight weeks, during which participants maintained their regular diets and physical activity levels to ensure that any improvements could be attributed to the supplements.
What Did the Researchers Find?
The results were promising, particularly for Spirulina.
Key Findings
Insulin sensitivity increased by 224.7% in the Spirulina group.
Insulin sensitivity increased by 60% in the soybean group.
100% of participants taking Spirulina showed improvement in insulin sensitivity.
69% of participants taking soybean experienced improvement.
Participants taking Spirulina were 1.45 times more likely to improve insulin sensitivity compared to those taking soybean.
These findings suggest that Spirulina may offer significantly greater benefits for improving insulin resistance among HIV patients than soybean supplementation.
Why Spirulina?

Spirulina is a nutrient-rich blue-green algae packed with:
High-quality plant protein
Essential amino acids
Vitamins and minerals
Antioxidants such as phycocyanin
Anti-inflammatory compounds
These nutrients may help reduce oxidative stress and inflammation—two factors closely linked to insulin resistance.
What Does This Mean for HIV Patients?
Managing insulin resistance is an important part of long-term HIV care. Affordable nutritional interventions like Spirulina could provide an additional strategy to support metabolic health, especially in communities where access to specialized medical treatments is limited.
However, it’s important to remember that this was a small pilot study, and larger clinical trials are needed to confirm these findings before Spirulina can be routinely recommended as part of HIV treatment.
Final Thoughts
This research highlights the potential of Spirulina platensis as a simple, accessible, and cost-effective nutritional supplement for improving insulin sensitivity in people living with HIV. While soybean also demonstrated benefits, Spirulina produced substantially greater improvements over the eight-week study period.
