Heard great things about blue spirulina
Organic Blue Spirulina Capsules Extract 8:1
Taking these blue spirulina capsules has become part of my morning routine. I feel a noticeable increase in stamina and concentration without any jitters. The potent extract helps cleanse my system and keeps me feeling balanced throughout the day. It’s great to have a product that aligns with my goal of living more naturally.
I originally chose them because it is an 8 to 1 phycocyanin extract rather than ordinary spirulina powder, plus there are no fillers or binders added. They have been especially useful on longer work days
Picked these up mainly to add something different to my fitness supplement routine. After taking them regularly I have noticed my energy feels steadier when I am training and I seem to stay mentally sharper afterwards instead of feeling completely drained
This product arrived promptly and there seems to be good evidence that blue spirulina has beneficial health effects
