The two to four weeks before travel affect both cell quality and test accuracy
Quick answer
Cellora states it uses functional test results to find the body's best window before cell collection, so preparation should start before travel: adequate sleep, less alcohol, no smoking, controlled diet, and full disclosure of medication and supplements — all of which affect both stem cell quality and test accuracy.
Sleep is the most overlooked factor yet clearly affects hormones, inflammation and recovery. Keeping consistent sleep for at least two weeks before testing makes results reflect your real state rather than temporary deprivation.
Alcohol affects liver function, inflammatory markers and sleep quality; reducing or stopping it before the trip makes results easier to interpret and lightens the body's load.
Smoking affects circulation and oxidative stress, directly relevant to the condition of cells to be collected. Discuss quitting with a physician well ahead of treatment.
On diet, no extreme change is needed: cutting highly processed food and sugar and drinking enough water is a foundation that helps both results and general wellbeing.
Disclose all medication and supplements, since some affect results — high-dose vitamins, drugs affecting blood clotting, certain herbal products. Never stop prescribed medication without consulting your doctor.
Finally, manage stress and allow rest early in the trip: long-haul travel and adjusting sleep affect the body in the first days, which may coincide with sample collection.
It depends on the supplement and the panels ordered; some directly affect results. Send the full list to the clinic in advance and follow the specific instructions given rather than stopping on your own.
Intense exercise close to testing can temporarily shift some values, notably muscle and inflammation markers. Ask the clinic about requirements in advance and keep your normal routine rather than making sudden changes.
