Mar 12, 2025
Nathalie Niddam, holistic nutritionist and peptide therapy expert who coaches on epigenetics, performance, and longevity. She recounts discovering peptides and explains prepping the immune system and lifestyle first. Topics include gut and musculoskeletal repair peptides, sleep and brain-supporting peptides, weight loss and thyroid strategies, and using adjuncts like molecular hydrogen for recovery.

Episode notes
Early Peptide Protocol Backfired And Changed Her Practice
- Nathalie described a protocol that initially worked then triggered immune reactions, shaping her cautious approach to peptides.
- She now levels immune balance first (thymus, alpha‑1, hydrogen) before adding stronger peptides to avoid reactions.
Do The Housekeeping Before Starting Peptides
- Do foundational work (sleep, diet, stress management) before aggressive peptide therapy so the body can respond properly.
- Use mild modulators like thymus peptides and molecular hydrogen first to create a stable platform for later peptides.
Thymic Peptides Rebalance Immunity And Aid Healing
- Thymic peptides (thymosin alpha‑1, thymosin beta‑4, thymulin) act as immune modulators that rebalance Th1/Th2/Th17 responses and reduce inflammation.
- TB4 fragments can be far more potent and orally available, offering antifibrotic and healing benefits with lower doses.
