Mastering Nutrition

Question: How can I protect against oxalates? Short Answer: Getting 300-400 mg calcium between food and supplements at each meal will minimize oxalate absorption. Maintaining postprandial urine pH in the 6.4-6.8 range by getting 3-5 grams of potassium per day from food or from organic acid salts such as potassium citrate will prevent its crystallization in the kidney. Reducing dietary oxalate will prevent any possible damage in the gut. This is a clip from a live Q&A session open to CMJ Masterpass members.

The podcast discusses the importance of keeping post-prandial blood glucose levels under 140 mg/dL to avoid negative effects on metabolism. It explores the relationship between sorbitol and plasma glucose levels, the significance of adaptation to postprandial glucose levels, and the importance of glycemic load adaptation for overall health.

This podcast discusses the historical synthesis of Methylene Blue in medicine, its role in rerouting electrons and therapeutic applications, the effects and risks of Methylene Blue including decreased brain connectivity, and its potential benefits as a disinfectant and in treating respiratory chain disorders.

Explore the uses and effects of methylene blue, from its historical background to its potential benefits for mitochondrial health. Learn about the redox reactions and the cycling process of methylene blue. Discover the role of complexes in cellular respiration and the interplay between fat, leucine, and the electron transport chain. Understand the complexity of the respiratory chain and the impact of nutrient deficiencies on energy metabolism.

Masterjohn, podcast host, explores the relationship between copper and estrogen in this episode. They discuss how estrogen moves copper from the mother's bloodstream to the fetus during pregnancy and how it promotes intestinal copper absorption. Maintaining pregnancy-level hormones while not pregnant poses a risk of promoting too much copper absorption. Copper status should be monitored when using supplemental hormones to avoid toxicity.

Exploring ways to slow or reverse graying of hair by addressing weak links in energy signaling, infrastructure of energy production, and antioxidant protection. Topics include the relationship between carbohydrate intake and thyroid hormone production, biology and factors contributing to hair graying, the effects of calcium pentathenate, and inborn errors of metabolism's influence on graying hair.

Question: How much iron can we absorb at once? Short Answer: High-dose iron will produce more total absorbed iron, but will also leave more in the gut, which could cause constipation or disturb the gut microbiome. If desperate for quick relief, 200 milligrams per day of iron taken in the morning will work faster than lower doses or the same dose taken in the afternoon. For most people, however, I believe it is best to start with 18 milligrams of iron, and only increase it to 27 or 36 milligrams, or higher, if needed. If it is difficult to raise iron with a supplement, try eating a temporary carnivore diet that includes egg yolks but not whites, or at least try taking your iron with a breakfast that matches this description.

Question: What cofactors are needed to synthesize and recycle BH4? Short Answer: Zinc, magnesium, potassium, and niacin are the cofactors needed for the synthesis and recycling of BH4. Folate and methylation are not involved, though high-dose folate or folic acid could hypothetically hurt BH4 recycling since both are recycled by dihydrofolate reductase (DHFR).
