"JOINCIRCLES enables you to own your own medical data. After buying an advanced biochemistry test here, we’ll send your test kit out the next working day. When your kit arrives, do the test and call our courier to collect – follow the simple instructions in the kit. The lab will take around 21 working days to analyse your sample from the time they receive your sample. When your results are ready, I'll email them directly to you. To get the full value from your results, we highly recommend that you contact a healthcare practitioner from our ‘Practitioner Circle’ to take you through your results. This will help you understand how and where to focus your efforts. They may suggest additional relevant blood, blood spot and urine biochemistry tests that you can do going forward, to measure and track your risks and potentials. After your consult, you could book a wellness coaching appointment with Margie to get you started and keep you on track. Once you have your biochemistry results, you can start shopping for your personalised nutrition, environment and lifestyle choices on This is how you start on your journey towards optimal wellness! Please contact me if you need help choosing the right test and/or practitioner for your needs". Dr Heidi |

Why is amino acid testing important?

"Amino acids, known as the "building blocks" of proteins, are found in every tissue of the body. They play a major role in nearly every chemical process that affects both physical and mental function including the formation of ligaments, tendons, bones, as well as antibodies and regulation of enzymes and blood transport proteins. Twenty different amino acids are used to synthesise proteins. If you would like to measure all your amino acids, please look at the '20 Amino Acids Test' as this measures all the essential + non-essential amino acids".
