Learn Nutritional Biochemistry today

Elevate your clinical practice with nutritional biochemistry knowledge

Understanding nutritional biochemistry is vital to effectively identifying and correcting diet-driven health disorders and imbalances. 



Understand the causes of metabolic dysfunction 

Learn how diet impacts health at a cellular level and understand the metabolic processes and biochemical pathways responsible for dysfunction and disease.

Address nutritional deficiencies with precision

Know which dietary interventions and nutritional supplements to prescribe to improve your clients’ health on an individual level.

Stop disease at the root through early detection

Interrupt the progression of disease through early detection and treat dysfunction at the cellular level through nutritional biochemistry.

Forget about trendy diets and supplements 

If you want to offer your clients or patients credible advice about diet, energy regulation, exercise, metabolism, or nutritional supplements, you need to understand the physiological principles of nutrition at a cellular and biochemical level

In this course, you’ll gain a solid understanding of nutritional biochemistry — and the confidence to critically evaluate conditions and prescribe therapeutic measures that really help your patients.

Why not try the first two modules (for free!) to get a sense of the wealth of value this course offers?

Understanding nutritional biochemistry makes you a better functional medicine practitioner

Functional medicine and nutrition are deeply intertwined. As a healthcare practitioner, you know that nutritional imbalances and deficiencies lie at the root of many common health complaints. 

This makes these health conditions relatively easy to treat, if we can correctly identify and treat the dietary deficiencies and nutritional imbalances responsible. 

In order to accurately diagnose metabolic dysfunction, practitioners need a solid understanding of cellular health and nutritional biochemistry.  
This includes: 
  • The body’s major biochemical metabolic pathways
  • What happens when these biochemical pathways dysfunction, and
  • How to treat the health conditions resulting from metabolic dysfunction.
Biochemistry is critical to the proper working of every cell in the human body, and every healthcare practitioner should have the knowledge and skills to evaluate and treat their client’s biochemistry and help them effectively.

This biochemistry course is different

Our comprehensive Nutritional Biochemistry course provides you with a deep foundational understanding of the physiological mechanisms at play in the biochemistry of nutrition. 
We’ve structured the program in such a way that you’ll be able to see the big picture before going into depth into each pathway. 

The knowledge is presented in a way that makes it easy to understand and retain the nutritional biochemistry concepts you’ll learn — and confidently apply them in your clinical practice.

You’ll soon feel confident applying your new knowledge of biochemistry and nutrition to help improve the lives of your clients and patients.
“The Metabolic Fitness Biochemistry course presented by Dr. Bryan Walsh is a must for those who want to understand the complexity of Biochemistry and be able to explain and provide a scientific approach to optimal health with each and every client.”
– Anne Dobbertin. NTP, RWS
“This is a must-do course for any nutritionist or exercise professional looking to fully understand the recommendations they are making, and the biochemical implications of the suggestions they make.”
Steve Grant. Nutritionist, London UK
“As an undergraduate and postgraduate student, biochemistry was a module that felt somewhat tedious and hard to grasp at times. Nevertheless, Bryan has the ability to turn biochemistry into an easy to understand process and interesting topic. This course gets my highest recommendation.”
– Jamie Rowan. Exercise and Nutrition Consultant

What is nutritional biochemistry?

Nutritional biochemistry is a field of study that allows us to understand the chemical processes and reactions that take place in our bodies in response to various nutrients at the molecular and cellular levels. 

In simpler terms, nutritional biochemistry helps us to understand how what we eat impacts our health. It’s essential to recognizing the roles that different nutrients — such as carbohydrates, proteins, fats, vitamins, and minerals — play in supporting essential physiological functions, metabolism, and overall health.

Key aspects of nutritional biochemistry include:

  • Nutrient metabolism: How the body processes and utilizes nutrients for energy, growth, and maintenance.
  • Nutrient functions: The specific roles of individual nutrients in various biochemical pathways and physiological processes.
  • Nutritional requirements: The optimal dietary and nutritional needs for both healthy individuals and those with specific health conditions. 
  • Impact on health: How nutrition influences the onset, progression, and management of diseases, including the prevention and treatment of various health conditions.
  • Biochemical therapy:  The use of specific nutrients or dietary interventions to address health issues and promote wellbeing.

Nutritional biochemistry plays a crucial role in shaping our understanding of the connections between diet and health. In turn, this understanding informs the dietary guidelines and personalized nutritional interventions we recommend to our clients for better health.
