KoopCast Omega 3 & Vitamin D for Exercise Induced Muscle Damage with Dan Owens, PhD #218
View all show notes and timestamps on the KoopCast website.
Episode overview:
Dan Owens is an associate professor in cellular and molecular exercise physiology at Liverpool John Moores University, Liverpool (UK). His research sits at the crossroads between nutrition, muscle metabolism, and muscle adaptation. In parallel to his academic career, Dan brings his passion for sports science to practice and has provided nutrition and physiology support for amateur and elite athletes across sports, including rugby union and league, ski and snow sports, football (soccer), and motorsports (Formula 1) and triathletes.
Episode highlights:
(23:00) Omega 3s: EPA and DHA fatty acids, mediating inflammation and oxidative stress, dietary intake before supplementation, mixed research results, high cost, use case for athletes coming off of surgery
(33:46) Vitamin D: claims, the big picture, a necessary vitamin rather than a performance aid, sources of Vitamin D, role in regulating calcium to the blood, the goal is to avoid deficiency
(52:08) Supplements for EIMD: avoiding deficiencies with omega 3s and vitamin D, proactive nutritional health, considering protein and polyphenols, low risk options

- Exercise-induced muscle damage: What is it, what causes it and what are the nutritional solutions?
- The Effects of Omega-3 Fatty Acid Supplementation on the Lipid Profile and Cardiovascular Markers Following Downhill Running in Long-Distance Runners
- What is known about the health effects of non-steroidal anti-inflammatory drug (NSAID) use in marathon and ultraendurance running: a scoping review
Vitamin D conversion for dietary/supplemental intake: 1 microgram = 40 IU (we suggest 1000-2000 IU per day vitamin D3 during winter)
Vitamin D blood concentration conversion: 1 ng/mL = 2.5 nmol/L (we aim for around 75 nmol/L)
