John Molvig, CISSN
Founder and Editor, The Shack
John Molvig is a certified sports nutritionist (CISSN, International Society of Sports Nutrition), Training and Development professional, and the founder of mjtacc.com, also known as The Shack. With fifteen years in management and service training across the health, travel, and small business sectors, John brings a people-first lens to everything he covers. His work in mental health began through personal experience supporting a partner with Borderline Personality Disorder, which led him to build one of earliest online resources on BPD. Diagnosed with Adult ADHD in 2016, he began researching nootropics and supplementation as part of his own wellness strategy, a path that eventually led to formal certification in sports nutrition. He now lives in New Jersey, consults with readers on cognitive support and stress resilience, and runs a curated shop of foundational compounds including L-theanine, choline sources, magnesium L-threonate, and high-DHA omega-3.
