My dear friend, i loved reading your blog. You have preferred oral and i can see genuine reasons for it. Vitamin B12 helps in creating Dna and red blood cells. You have almost added every information regarding it but let me add one more info. Formation of red blood cells is done inside bone marrow and it is called as Erythrocytopoesis. As you told , it requires Vitamin B12, folic acid and iron. Well i myself fear a lot from injections and prefer mostly oral but through injecting it produces immediate effects.
Your last information related to period cramps got my heart because it is very painful for me as well as many girls.
Can you tell upon boiling which leaves gives relief from period pain ?!
Thanks for the informative blog.
Greetings from my side ❤ 😍
