Am pleased to hear of this amazing product, but do not have an answer as to whether it is available in SA.
The basic ingredients are amino acids, essential & non essential; as well as a synthetic blend (Caysine) which assists in chelation & removal of unwanted calcium & metals. It also has powerful anti-oxidants. For this , I am able to recommend a metal detox, as well as a product for calcium metabolism. Angioprim is described as a chelation formula which aids in the removal of unwanted Calcium & metals.
However, you mention you are a Type 2 Diabetic. This is a direct link to circulation & the blue colour of your legs.
I suggest you contact your medical practitioner & seek his advice.
I wish you well.
Kind regards, Felicia
