Dr. Colleen Huber continues her series on cancer biochemistry by explaining the critical roles of Vitamins B2 (riboflavin) and B3 (niacin) in preventing cancer. Referencing Nobel Prize winner Otto Warburg’s 1931 research, she states that the common cause of cancer is “irreversible injury of respiration” — meaning damage to the cell’s ability to produce energy through oxidative phosphorylation in the mitochondria.

We break down the biochemistry in this clear, eye-opening video: how thiamine pushes pyruvate toward healthy energy production instead of the lactic-acid cancer pathway, plus the best foods (fish, beans, asparagus & more) to keep levels topped up.

Dr. Colleen Huber shares the results of her clinic’s landmark 2014 study: cancer patients who cut out sugar had dramatically better outcomes, even with the same IV treatments. See how cancer “lights up” on PET scans while normal tissue stays dark, and learn exactly what to avoid. This changes everything.

This is how sugar actually feeds cancer. Dr. Colleen Huber breaks down the biochemistry: damaged mitochondria block normal energy production, forcing sugar straight into the lactic acid pathway that builds cancer.

Adenine used to be called Vitamin B4. This nutrient is critical to our building of DNA and RNA. Adenine is also necessary to make new cellular energy in the form of ADP and ATP. If we don’t have enough to make the ATP then the whole road gets closed off, and again metabolic traffic gets diverted over to the cancer pathway.

Vitamin C has been appreciated for decades for its role against cancer as a pro-oxidant. Recent research has shown why vitamin C’s effect in killing cancer is more permanent than the effects of chemotherapy. Vitamin C can kill cancer cells and it has crucial effects against cancer stem cells. In intravenous form we can give enough vitamin C to have an anti-cancer effect.

Vitamin B5 is also known as pantothenic acid. It is crucial for the formation of Coenzyme A. Coenzyme A is necessary to form Acetyl CoA. Without enough Acetyl CoA, the traffic of metabolism is diverted over to the cancer pathway and the the lactic acid fermentation route.

Biotin performs a function that is not often appreciated: the conversion of pyruvate directly to oxaloacetate, bypassing the normally essential molecule Acetyl CoA. There is more than one path into the mitochondria. Biotin enables this other pathway into the mitochondria. Without biotin or these other B vitamins you are forced into the cancer pathway.

Vitamin B12 is crucial for the formation of healthy red blood cells and for proper DNA synthesis. Without sufficient B12, normal cellular metabolism can be impaired. This can contribute to diverting metabolism toward the cancer pathway. Maintaining adequate Vitamin B12 supports the healthy mitochondrial processes that help protect against cancer.

The role of CoQ10 regarding cancer. In this ongoing series on cancer and biochemistry we shed light on the role of a specific nutrient with regard to cancer. We have been looking at the electron transport chain which is our internal powerhouse. CoQ10 enables an accumulation of protons in the space between the mitochondrial membranes and this is the material needed for the last essential step of the electron transport chain which is the conversion of ADP to ATP.

Today we talk about exercise, mitochondria, and cancer. In previous videos in this series we paid a lot of attention to the mitochondrion. Exercise is the most certain way to increase mitochondria in your body. A 2016 study of over a million people showed regular exercise cuts risk for 13 different types of cancer.

Dr. Colleen Huber explains the citric acid cycle, also known as the Krebs cycle, which takes place inside the mitochondria. This cycle is the normal metabolic pathway that efficiently produces energy while steering the body away from cancer metabolism. Insufficient amino acids can obstruct the cycle, causing pyruvate to be diverted into the lactic acid pathway that favors cancer.

Dr. Colleen Huber examines the amino acids alanine, serine, and glycine.
