Transparency · Avicenna Engine™
How we work
We give you a compass, so you know what you have and where you stand on the path to recovery.
Avicenna Engine™ is our clinical pattern engine, named after Ibn Sina (Avicenna), the 11th-century physician whose Canon of Medicine was the standard medical textbook in Europe and the Islamic world for 600 years. The Avicenna principle: analyse the whole person, not one symptom in isolation. Look at patterns, context, lifestyle, temperament. We follow that legacy.
Our brand isn't called Fitrah Recovery by accident. Fitrah stands for the natural state in which the body functions optimally. Avicenna saw that as the goal of medicine: bringing the body back to that equilibrium. We translate that into three things: bloodwork read in Avicenna optimum context, recovery plans and protocols grounded in evidence tiers T1 to T6, and patterns that connect what isolated markers cannot.
The healthcare system today often runs from symptom to pill, or from specialist to specialist. For isolated acute issues that works well. For chronic, layered complaints there's a missing layer: the pattern across your full bloodwork, your lifestyle, your context. Every body carries a blueprint. Your bloodwork and how you feel together give signals. We help read those signals so possible causes become visible, not just symptoms calmed. Your doctor remains indispensable for diagnosis and treatment. We add the context and pattern work that can't be built in a short consult.
What is Avicenna optimum?
Lab reference ranges are population statistics: the range where 95% of people who visit a doctor fall. That says little about what's optimal for you.
Avicenna optimum comes from outcome research: ranges where people feel best in energy, sleep, mood, and recovery. Those ranges are often tighter than 'normal per lab'.
Example: ferritin 'normal' is 11-307 µg/L (same number as ng/mL in the US). The Avicenna optimum is 50-150 µg/L. Someone with ferritin 16 sits 'within the norm' but often feels tired, short of breath, with hair shedding. Hair shedding is one of the earliest signs of suboptimal ferritin in women.
Pattern, not one marker
One marker off is information. A combination of markers together tells the story. A ferritin of 9 in isolation is one thing; a ferritin of 9 with folate below 5, B12 at the edge, and vitamin D below 25 is another. The first asks for replenishment. The second asks for sequence: helpers first, then iron.
We do not read one marker at a time. We read the combination together, plus your biological sex, what you have already taken, and how your values move across uploads. Each combination needs a different answer, and that is exactly why generic iron advice works for some and not for others.
This is not a claim that we do something a clinician cannot. A clinician has ten minutes with you and cannot order every test. We have the room to draw out the combination and make the sequence visible, so you know what your clinician can confirm or adjust.
Every marker in context
We read each marker not as an isolated number, but across several layers of context at once. The underlying rules are hand-curated and traceable to the published source.
Example: ferritin 50 means something different for someone tired for months than for someone who feels great. We weigh that context, for every marker.
Evidence tiers T1 to T6
Not all sources are equally strong. We label each basis with an evidence tier so you know where a recommendation comes from:
T1: Systematic reviews, meta-analyses and large randomised trials (Cochrane, NEJM, BMJ, The Lancet) — the strongest basis
T2: A single randomised trial, or a large cohort study
T3: Case series, small cohort studies and in-vitro work
T4: Published guidelines and expert consensus (WHO, NICE, ACG, NHG)
T5: Traditional and historical sources — the Canon of Ibn Sina, classical TCM texts
T6: Anecdotal: individual experience reports from the community
Lab ranges rest on T1 to T3. A guideline (T4) can confirm or bound such a value, but never sets it alone. T5 and T6 provide context and never a reference value: of the 154 markers with their own optimum, not one rests on T5 or T6.
What we don't claim
No diagnosis. No substitute for your doctor. No treatment. We build a reading guide based on patterns we often see in similar complaints.
Avicenna optimum is a question for your doctor, not a claim your doctor must accept. Not every doctor works with these ranges, and that's their right.
We are not a medication substitute. Never stop medication without talking to the prescribing physician.
