NAD+ & Peptide Therapy in Knoxville
At Fountain of Youth Medical in Knoxville, Lynne Worthington and Tim Fox are committed to therapies that go beyond surface-level changes—addressing your wellness from the cellular level. Two of our most advanced offerings are NAD+ (nicotinamide adenine dinucleotide) and Peptide Therapy, each designed to support energy, repair, vitality, and sexual/functional performance.
What Is NAD+ Therapy?
NAD+ is a vital coenzyme found in every cell of your body. It plays a central role in energy production, DNA repair, mitochondrial health, and metabolic function. As we age or endure chronic stress, NAD+ levels naturally decline, which can contribute to fatigue, brain fog, slowed recovery, and loss of vitality.
At Fountain of Youth Medical, we offer medically-guided NAD+ therapy protocols, customized to your biomarkers and wellness goals. Through infusion or injection formats, we support mitochondrial revitalization, cognitive clarity, improved metabolism, and enhanced overall function.
What Is Peptide Therapy?
Peptides are small chains of amino acids — natural messenger molecules in the body that regulate processes such as hormone release, tissue repair, metabolic response, sexual function, immune regulation, and more.
With peptide therapy at our clinic, we design protocols that:
- Stimulate hormonal balance and sexual health (for both men & women)
- Enhance muscle repair, lean mass, and recovery from workouts or injury
- Support skin regeneration, collagen production, and reduce age-related deterioration
- Improve mood, energy, slee,p and overall functional performance
Why Combine NAD+ & Peptide Therapy?
Combining NAD+ and peptides can be powerful. While NAD+ addresses fundamental cellular metabolism and mitochondrial health, peptides can fine-tune signaling pathways (hormones, tissue repair, sexual responsiveness), creating a more holistic restoration of function.
At Fountain of Youth Medical, Lynne & Tim build a personalized plan: beginning with diagnostics (lab work, symptom review, goals) → selecting the optimal delivery method → monitoring progress and refining the protocol for results that last.
What Can You Expect?
Initial Consultation: Review of your health history, lifestyle, symptoms (e.g., low energy, sexual function issues, mood changes, poor recovery, etc.)
Diagnostic Testing: Bloodwork and biomarkers to assess NAD+ levels, hormone status, metabolic markers, and relevant peptides
Therapy Selection & Delivery: Depending on your goals, we may recommend NAD+ infusion or injection, peptide injections, and possibly topical peptide applications
Timeline for Results: Many patients begin noticing improved energy, clarity, sexual responsiveness, or better recovery within weeks. More profound changes may take a few months and depend on consistency and overall health.
Ongoing Monitoring & Optimization: We follow up, adjust therapies, and ensure you are getting maximum benefit while maintaining safety and efficacy.
