The connection between biology and mental wellness is well established. Mitochondrial function, neurotransmitter production, sleep quality, and gut health all directly affect anxiety, mood, and stress resilience. Several compounds address these biological factors through mechanisms that complement rather than replace conventional mental health approaches.
Important: The compounds discussed on this page are not treatments for anxiety disorders or mental health conditions. They do not replace therapy, psychiatric care, or prescribed mental health medications. If you are experiencing significant anxiety or mental health challenges, please speak with a qualified mental health provider. These compounds may be explored as complementary tools in conversation with your physician and mental health team.
The biology of anxiety and stress
Anxiety and chronic stress are not purely psychological phenomena. They have measurable biological correlates including elevated cortisol, disrupted sleep architecture, mitochondrial dysfunction in neurons, gut-brain axis dysregulation, and neurotransmitter imbalances. Compounds that address these underlying biological factors can meaningfully support stress resilience and mental wellness as part of a broader approach.
Compounds available through Tides
Methylene Blue
Methylene Blue supports mitochondrial energy production in brain cells and acts as a neuroprotective antioxidant in neural tissue. Some people use it for mood regulation and cognitive support, particularly cognitive fatigue and stress-related mental fog. It is available through Tides as a physician-prescribed protocol. Note: Methylene Blue must not be combined with serotonergic medications including SSRIs, SNRIs, MAOIs, or triptans without explicit physician guidance due to the risk of serotonin syndrome.
NAD+
NAD+ supports cellular energy production and plays a role in neurotransmitter synthesis and circadian rhythm regulation. People using NAD+ often report improvements in mental clarity, reduced fatigue, and more consistent energy throughout the day. These effects may support stress tolerance and emotional regulation in people dealing with burnout or chronic low energy.
Sermorelin
Sermorelin restores more natural growth hormone levels, which play a role in mood, cognitive function, and sleep quality. Many people using Sermorelin for anti-aging purposes notice that mood and stress resilience improve alongside the physical benefits. Better sleep quality, which Sermorelin typically improves within two to four weeks, has a well-documented positive effect on daytime anxiety and stress tolerance.
The gut-brain connection
Over 90 percent of serotonin is produced in the gut. Gut health directly affects mood and anxiety through this pathway and through the vagus nerve, which connects the gut and the brain. Compounds that support gut health and reduce intestinal inflammation may therefore have meaningful effects on mental wellness. Glutathione, for its antioxidant and anti-inflammatory properties, may support this pathway as part of a broader protocol. Always discuss with your physician.
Approaches compared
| Approach | Mechanism | Important notes |
|---|---|---|
| Methylene Blue (Tides) | Mitochondrial support in neurons | Do not combine with serotonergic drugs |
| NAD+ (Tides) | Cellular energy and circadian support | Well-tolerated, broad wellness benefits |
| Sermorelin (Tides) | GH and sleep quality | Improves sleep and mood over weeks to months |
| Conventional therapy | Behavioral and psychological | First-line for anxiety disorders |
| Prescribed medications | Neurotransmitter modulation | Overseen by psychiatrist or GP |
How to get started through Tides
Start with an online health assessment covering your health history, symptoms, goals, and all current medications. It takes about five minutes. Disclosing all medications, including psychiatric medications, is essential before starting any new protocol.
A licensed physician reviews your assessment and determines which compounds are appropriate. If you are on serotonergic medications, Methylene Blue will not be prescribed due to the interaction risk. Your physician will identify the safest and most appropriate protocol for your situation.
Prescriptions are filled at a licensed U.S. compounding pharmacy and shipped to your door. Your physician is available throughout your protocol. This is not a replacement for your mental health care team.
What to expect
These are not fast-acting interventions. The biological changes they support (mitochondrial function, sleep quality, gut-brain signaling) build gradually over weeks and months. Here is a realistic timeline by compound:
Methylene Blue: cognitive clarity and reduced mental fatigue are often the first changes people notice, typically within one to two weeks. The effect is described as feeling sharper and less depleted during mentally demanding tasks rather than any dramatic shift in mood.
NAD+: energy and mental clarity improvements typically appear within two to four weeks. People commonly describe this as having more consistent baseline energy and less afternoon cognitive fatigue.
Sermorelin: sleep quality improvement is usually noticed within two to four weeks, which itself has a meaningful effect on daytime anxiety and stress tolerance. Mood and stress resilience improvements build more gradually over six to twelve weeks as growth hormone levels normalize.
Overall mental wellness improvements accumulate over time and are most pronounced when these protocols are used alongside therapy, good sleep habits, and the guidance of your mental health team.
