Functional Medicine
for your health goals
Functional medicine uses cutting-edge diagnostics to gain medical insights on the root cause of a disease. It maps out a body’s ecosystem and addresses dysfunctions with diet, supplements and lifestyle changes backed by science. Functional medicine focuses not only on disease resolution, but also early prevention by reducing risk factors that promote disease.
Comprehensive diagnostics
Go beyond symptom-chasing. We run thorough blood, stool, urine, saliva and imaging panels through trusted lab networks in India and abroad to map what’s driving your health.
Stepwise protocols
Walk out with a concise 90-day plan – food, supplements and lifestyle – with exact doses and timing you can implement yourself.
Personalised to your
biology & context
Built from your labs, symptoms, and lifestyle – and tailored to Indian realities (budget, availability, food culture, work schedule).
Meet Yohan Tengra
I’m a functional-medicine consultant and educator. After years of trial-and-error, I shifted to a diagnostics-first approach that finds root causes and turns them into clear plans you can follow to fix your issues. Today I help patients get measurable results – and I train practitioners to apply the same system.
Chronic lifestyle diseases kill 41million people each
year, equivalent to 74% of all deaths globally.

From research to real-world, faster
New findings can take years to reach routine care. I read the literature continuously and translate it into practical, safe recommendations – for patients seeking outcomes and practitioners who want what actually works. Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Built to complement your medical care
Chronic illnesses are on the rise and a patient needs everything at their disposal to get better. I’m pro-collaboration: some cases require a specialist or medical professional to get on board. As long as the treatment is evidence based we don’t believe in dismissing other fields of medicine.
What our students and
clients have to say!
Pushkar Arora
Fungal skin infection, IBS, Watery ears, Heart palpitations, Foggy urine, Flatulence, Dandruff and more
For years, l’ve struggled with a severe fungal skin infection, IBS and experienced 46 different symptoms. Many doctors ignored my concerns, gave me a vitamin medicine, and sent me away. They even dismissed my concerning blood test results. But Yohan is different. He carefully studied my symptoms and blood work. He researched and analyzed the hell out of every detail to understand my condition.The good part is he is obsessed about his work. And his obsession helped me heal. I’ve seen multiple practitioners, yet no one has ever explained the reasons behind each of my issues as clearly as he has. He has gone above and beyond to help, even in recommending cost-effective supplements. Three months after starting Yohan’s protocol, there has been a noticeable improvement in symptoms. Skin issues 50% resolved, stress levels down by 40%, brain fog gone by 70%. Sleep issues and fatigue improved by about 20% each. Eye itchiness and anal itching are both 80% better. Hair fall reduced by 80%, sugar cravings by 50%, and headaches by 80%. Right abdominal pain has improved by 60%, watery ears by 90%, and mouth ulcers by 70%. Palpitations have reduced by 90%, chest burning by 70%, and burning sensations in the stomach by 60%. Foggy, smelly urine is about 70% resolved, while the feeling of incomplete stool passing has improved by 90%. Flatulence is 80% better, dandruff is about 40% resolved and bloating has reduced by about 50%. Overall, there has been significant progress across multiple symptoms.
Geetha
Alopecia areata, PCOS, insulin resistance, Poor gut health
My name is Geetha and I contacted Yohan in Jan for my 16 year old daughter who found a bald patch on her head which the doctor diagnosed as alopecia areata. Flew down to India and did all the tests, which felt like a lot of tests but was explained very well by Yohan as to why the tests were necessary to see the big picture. Yohan really assisted us through the tests process along with follow up with the diagnostic centers. Gave me a supplement protocol. There were many underlying issues to deal with like pcos, insulin resistance etc. Six months later we redid the tests and all the parameters are perfect. Hair is growing on all the bald spots, also pcos resolved. And currently on the gut protocol.What I realised is Yohan although so young is very knowledgeable in his field. There are so few who have done so much research on various ailments. His approach is very scientific and it works.
Tanya Pal
Juvenile idiopathic arthritis, Poor gut health, OCD, Depression
There is no pain or swelling in ankle, fingers and jaw joint now. I saw massive relief in gut issues within the first month itself. I am able to eat much more and digestion is so much better. Have also gained 2 kgs weight. I get gut discomfort only on days when something is off with my lifestyle or compliance in protocol unlike earlier when it occurred after every meal. Last month I realized I was effortlessly feeling happy and motivated. After brief depressive episodes of 1-2 days, I would now bounce back quicker and with less effort than before.Last week I also realized that OCD urges have considerably reduced without me putting any extra mental effort. I have seen great relief in my juvenile idiopathic arthritis symptoms. so grateful I came across Yohan’s episode on dostcast where I first learned about him. What convinced me was the way his consultation guide was written, it reflected his genuine intention to help clients by saving their money wherever possible. That sincerity was the push I needed. I’m deeply thankful to him for everything.
Mohini Surwadkar
Acne, Constipation, Diarrhea and other gut issues
After starting Yohan’s protocol, my stools have started to form better, they are not as mushy as before. Both my diarrhea and constipation episodes have reduced significantly. I don’t feel gassy all day anymore, except around my periods. I no longer feel irritated all day like I used to because of constipation. My sleep has improved. I wake up less during the night. My acne has decreased by 70-80%, and I feel so much better about my face. Seeing my GI map report has cleared up all my doubts. I finally have proof that something was wrong with my gut, and now no one can dismiss it. Just eating healthy, exercising and taking random probiotics don’t solve these issues. No doctor could have figured all of this out. Coming from a very humble background, the money I spent was a huge amount for me but Yohan’s deep understanding of the human body and evidence based approach gave me the confidence to trust him completely and make this investment.
Mudassir Ahmed
Seborrheic dermatitis, High cholesterol, severe dandruff
I knew Yohan as the Chief Knowledge Officer at a company, so I sought his expertise to address my bloodwork and health concerns after he started his independent practice. My primary goals were to lower my cholesterol and find answers for my severe dandruff issues. From the very beginning, I was impressed by Yohan’s commitment to using strong clinical evidence before prescribing any interventions. His vast experience in research was evident in his approach to my concerns. Through his detailed blood chemistry analysis and functional medicine protocols, I achieved significant health improvements. My cholesterol levels dropped to the desired range, my nutrient deficiencies improved, methylation was also addressed, and most importantly, my SEBORRHAIC DERMATITIS which had troubled me for years and went undiagnosed by other doctors, was accurately diagnosed and resolved.
Tanni Chopra
As a Functional Nutritionist deeply invested in true, root-level healing, I thought I had seen the full landscape of wellness. But attending Yohan Tengra’s Biohacking Mastery course shattered that ceiling. It wasn’t just an experience – it was a complete system upgrade. Yohan doesn’t just teach biohacking; he lives it, breathes it, and transmits it with a clarity and intensity that’s rare to find. Every session felt like plugging into a hidden matrix of knowledge that our modern world desperately needs but rarely reveals. The depth of research, the razor-sharp articulation, and the uncompromising focus on real-world application transformed my understanding of health, resilience, and peak performance.
Bhuvana Suresh
So happy and grateful to have learnt from one of the brightest young minds in the functional nutrition space ! The entire course with over 60 plus modules of world class nutritional science – meticulously researched, organized ,compiled and presented – bears only one exceptionally talented,hardworking young man’s name on it – yohan!! that’s an incredible achievement!
Pash Contractor
It was my real pleasure and good fortune to have participated in the introductory course offered by Yohan Tengra of Biohacking India.
Yohan’s Course is Advanced enough for the discerning Medical Practioner, at the same time simple enough for a Beginner to follow.
It’s extremely indepth but the outcomes come with ease. Having lost my faith in traditional medicine, I must say that Yohan’s Course has done a lot to put my faith back into conventional medical Trials etc. I highly recommend this course to any budding Functional Nutrition aspirants as also to Medical Doctors who would greatly increase the scope of their medical outlook after doing this amazing course.
Kartik Sivadass
This course was one of the best investments l’ve made, and it was truly transformative. It provided an in-depth understanding of how to read, analyze, and interpret scientific studies. It also taught me how to accurately diagnose health issues by understanding blood markers and other medical reports. I particularly liked how the course debunked many common diet fads. I highly recommend this course to anyone who wants to dive into functional nutrition.
Manjit Sharma
I was part of the first batch of Biohacking Mastery Course by yohan. This course sped up my learning path or else I might have to spend months & years and still can’t get all these knowledge together. Most important thing I have learned is how to read research papers and evaluate the data based on the strength & type of the study. The reference range data is very helpful to get idea of bloodmarkers which prevents many things from going wrong. Every session is comprehensively covered, You get more than Yohan promised for this course. There is no bias and its completely scientific Best place to learn functional medicine.
Harsh Thakkar
Fatigue, Brain fog, Insomnia
Very grateful that i get to say im feeling so much better from Yohan’s 3 month course. Fatigue : massive improvement. 90%. energy levels are peaking these days. unreal. can’t believe i used to push myself so much in a body that just could not support. brain fog: most days 80% improvement. this was one of my biggest concerns. i used to dread not sleeping well because the next day would be such a challenge to get through, but, now even with poor sleep, brain fog is still manageable. sleep: most days 90% improvement. best part is I am no longer anxious about sleep. even if i dont get sleep on some days, im able to function well enough for atleast 1-2 days. w/o isleephas also been fairly decent on some days.
Ipsa Sandhiya
PMS, Hashimotos, Migraines, Fatigue, Breathlessness
I am truly thankful for Yohan’s support. The supplement he gave me for PMS has completely changed my life, and I’m so grateful! I only vomited once on the first day (during the first month of the protocol). Apart from that, everything has been normal: no cramps, no bloating, just slight discomfort, which I believe will improve over time as my hormones become perfectly balanced. Breathlessness has reduced. Fatigue levels have noticeably improved! I used to get mild headaches when traveling in a car in plain areas, likely due to motion sickness. Recently, I went on a car trip and was relieved to experience no headaches at all! Brittle skin on my hands has improved slightly.
Kyra Shroff
Type 1 Diabetes (Insulin dependant), Fatigue, Sleep issues, Poor athletic performance
I have known and followed Yohan’s work for quite some time decided to consult him after my father’s consultation because I was so intrigued by his work.
As a type 1 insulin-dependent diabetic, I have always sought ways to better manage my condition and working with Yohan has been an excellent experience. He is approachable, attentive, and generous in sharing his knowledge, guiding you clearly and professionally throughout the process.
After completing his 3 month protocol, I have observed significant improvements: sleep quality,
energy levels and athletic performance have improved, fatigue has diminished, and most notably, my insulin sensitivity and glycemic control have advanced considerably — allowing me to safely reduce my insulin requirements.
What stands out most is the confidence of having a trusted professional by my side. I plan to continue consulting with Yohan several times a year, not due to illness, but to safeguard my health and ensure that I continue to thrive.

Sangeetha Iyer
Nutritionist
- Appeared on multiple podcasts like Dr. Pal, Dostcast, Something Bigger Show
Being part of Yohan’s first mentorship course/program was nothing short of a master class in evidence based nutrition. The key reason for me to be a part of this program was to be updated with what research and studies were actually alluding to especially on controversial subjects like LDL/ ApoB, dietary strategies, Seed oils and the like.
One of the most valuable aspects was recognizing my own biases around food and health—
something I hadn’t even realized was holding me back. I especially appreciate the detailed guidance on supplement dosages and strategies, which helped me in making smarter, safer choices for my clients. Overall, it was an empowering experience that has truly added value to the way I approach nutrition strategies for preventive care, health and well ness.
