 [ Symptoms ] avoid stem cell pills if have lupus is blue green algae a stem cell rejuvenator [ Disease ] i am sorry to hear you are coping with lupus or at least that is how it sounds it is a nasty disease to clarify your question there is no such thing as stem cell pills  stem cells currently are used only in research and even then only for research into very specific conditions i am not sure what a stem cell rejuvenator would be this sounds like marketing hype to me blue green algae is a supplement generally considered safe for most people to take at the very least it probably will not harm you assuming you are not allergic to it blue green algae is often touted as being high in protein  but you would have to take it in massive quantities to achieve the amount of protein you would get from say a glass of milk according to the webmd article i linked above blue green algae is currently being studied for any positive effect on the immune system if it does support immune health and there is no definitive answer to that question yet it could be beneficial to someone with lupus often when a person has a chronic disease like lupus they will try almost anything to cure their symptoms or at least find relief from them please do not fall for any marketing hype and waste your money on products that have not been proven to help with lupus symptoms rely on your health care provider is advice in terms of medications and heed the healthy living advice you find from reputable sources like the national institutes of health and the lupus foundation of america best wishes to you
