Exclusive7 Core Supplements to Boost Strength, Weight Loss After 60 | Doug Spiel, MD｜Vital Signs

When Dr. Douglas Spiel began rebuilding his health after a severe autoimmune illness, his first concern wasn’t how much he could lift or how often he trained. It was whether his body still had the biological capacity to recover at all.

Months of corticosteroid treatment had left the board-certified radiologist with muscle loss, insulin resistance, fat gain, and declining energy—common consequences for patients who survive autoimmune disease. Spiel chose not to pursue hormone replacement therapy or performance-enhancing drugs. Instead, he focused on supporting the systems that quietly determine aging: metabolism, mitochondrial energy production, inflammation control, and cellular repair.

On “Vital Signs with Brendon Fallon,” Spiel highlighted key nutraceuticals that enabled him to recover, at 60, the strength and vitality he’d had more than 10 years earlier.

His approach centered on a carefully structured nutraceutical regimen. Spiel selected compounds linked to glucose regulation, vascular health, muscle signaling, and declining cellular energy pathways such as NAD⁺. He paid particular attention to autophagy—the process by which the body clears damaged cells—and to improving insulin sensitivity, which he describes as foundational to recovery.

Timing mattered as much as selection. Some supplements were taken on an empty stomach, others with fat, and others later in the day to support stress regulation and sleep.

“It’s not about taking more,” Spiel said. “It’s about supporting the right systems at the right time.”

Training factored heavily into his recovery. Preserving muscle helped stabilize metabolism, making the broader strategy more effective.

On “Vital Signs,” Spiel presents a regimen of preventative maintenance designed to restore the body’s ability to repair itself before decline becomes irreversible.
