You may have heard claims that C:15 (pentadecanoic acid) is the first essential fat discovered in 90 years, a powerful longevity booster, and a game-changer for metabolic health. But how much of this is backed by solid science?

In this episode, I sit down with Dr. Bill Harris, a leading expert in fatty acid research, to critically evaluate the evidence behind C:15. We break down the population studies linking it to health benefits, the key clinical trials testing its effects, and whether the marketing around Fatty15 is ahead of the actual data.

In this episode, we cover:

• What exactly is C:15, and how does it compare to other fats?
• The claim that C:15 is an essential nutrient—does it meet the criteria?
• The current evidence on C:15 and its impact on cholesterol, glucose, and inflammation
• Does C:15 supplementation mimic omega-3s, metformin, or rapamycin?
• The broader issue of patenting a naturally occurring compound

Think creatine supplementation is all about timing and loading?

You might be surprised. In episode #350, I dive into six frequently asked questions about creatine, inspired by a follow-up review by Dr. Jose Antonio and colleagues. Whether you’re just starting with creatine or already supplementing, this episode will provide clarity and practical insights.

Learn why timing matters less than consistency, whether co-supplements like carbs enhance effectiveness, and if creatine affects blood pressure, fertility, or urine production. This is your ultimate guide to making informed decisions about creatine supplementation.

Key highlights include:

• Does the timing of creatine intake matter?
• Do other compounds enhance creatine’s effectiveness?
• Does creatine affect blood pressure or increase urine production?
• Is creatine safe to use during pregnancy?
• Can creatine supplementation impact male fertility?

Discover insights and supporting studies in the full show notes.
