Spirulina boosts iron absorption effectively
We aimed to explore the potential of microalgae, particularly Spirulina, as a solution for iron-deficiency anemia. In a study with rats, different microalgal diets were tested to evaluate their effects on hemoglobin levels.
Our findings showed that rats fed high concentrations of Spirulina had the best hemoglobin regeneration, outperforming other groups. Notably, Spirulina provided more intestinal nanosized iron than other microalgal variations. This indicates that Spirulina could be an effective iron supplement for addressing anemia.

We examined how spirulina supplementation might help adults with ulcerative colitis (UC) manage anemia. In a randomized, double-blinded study with 80 participants, half received 1 g/day of spirulina while the other half took a placebo over eight weeks.
The results showed a significant increase in serum iron and improved anemia parameters for the spirulina group compared to the placebo. However, no noticeable changes were observed in fecal occult blood tests. While these findings are promising, further long-term studies are needed to confirm spirulina's benefits for anemia management in UC.

Spirulina shows potential for anemia
We examined how spirulina, a nutritional supplement, affects anemia in young children from underprivileged settings in Cambodia. In a carefully designed study, participants received either spirulina or a placebo in a randomized, crossover format.
While we noticed a slight increase in weight among the children taking spirulina, the improvements were not statistically significant enough to make strong claims. Encouragingly, the number of anemic children did decrease significantly with spirulina, suggesting potential benefits worth investigating further.

Significant result

While treating my anemia alongside iron fumarate, my ferritin levels increased from 8 to 41! I'm thrilled with this significant result. The only downside is the large capsule size; I sometimes need to cut them up to swallow comfortably.

Spirulina shows promise in anemia
We explored the effects of a naturopathic approach on an infant diagnosed with hereditary spherocytosis, a form of inherited hemolytic anemia. After receiving multiple blood transfusions, the patient began treatment with spirulina and chlorophyll. Remarkably, he was able to maintain normal hemoglobin levels and has not required additional blood transfusions for over seven months following the start of this therapy. This case suggests that natural interventions could support hemoglobin levels in patients with this condition.

Spirulina improves anemia in rodents
We investigated how dietary spirulina, or Arthrospira platensis, might protect against anemia caused by lead exposure in adult male rats.
The study set up different groups: a control, spirulina-only, lead-only, and a combination of lead and spirulina.
After 30 days, rats exposed to lead showed serious kidney damage and changes in blood parameters. Yet, when spirulina was added to their diet, improvements were notable in kidney health and blood conditions, likely due to its high antioxidant properties.
Ultimately, we see that spirulina can play a significant role in mitigating anemia linked to lead toxicity.

We examined the effects of spirulina supplementation on children with beta-thalassemia major, focusing on hemoglobin levels and heart health. In a study involving 60 affected children and a control group of 30 healthy peers, participants received spirulina for three months.
By the end of the study, we noticed a significant improvement in hemoglobin levels and a decrease in the need for blood transfusions among the children. Additionally, heart function, measured through specific imaging techniques, showed promising enhancements. This suggests that spirulina could be a valuable aid in managing anemia and cardiac health in these young patients.

We investigated whether Spirulina could improve anemia and immune function in seniors over 50.
During our 12-week study, 40 participants took Spirulina supplements while we monitored their health through blood tests.
Notably, we observed an increase in hemoglobin levels and immune function markers among participants, especially older women, who showed quicker benefits.
While the results are promising, further large-scale studies are essential to confirm these findings.
