Immune system boost
16 people found this helpful
This gives my immune system the boost it needs! I take a supplement first thing in the morning, which wakes me up and energises my day. I work with young children who pass around colds and viruses, but I haven’t fallen ill at all. This product has strengthened my immune system against the colds and infections around me! I also take wheatgrass supplements with Spirulina, and now I feel more energetic throughout my day.

Energised immunity
After a course of Spirulina, I've developed a notable boost in energy and vigour. It particularly enhanced my immunity during the winter when many were falling ill with colds, and I avoided getting sick even after exposure to cold conditions. I occasionally got my feet wet in street floods, yet I remained unaffected by colds.

Immune support
Miracle of Spirulina! Spirulina is a remarkable source of protein and works effectively alongside green algae. My hemoglobin dropped to 72, but after taking 4 capsules daily for a month, it rose to 122. I maintained this for a year, during which I didn't catch a single cold. Now, I continue to take it preventatively.

Less cold risk
I used to take 500mg and felt little effect, so I decided to double the dosage this time. I feel that I’m less susceptible to catching a cold.

Cold prevention
I genuinely appreciate this spirulina! I consume it in courses during autumn and spring as a rich source of vitamins and minerals. Over the last few years, I haven't experienced any colds, which I attribute to spirulina.
