Top 7 Supplements for Holistic Health (Backed by Science)

Supporting the mind, body, and spirit is at the heart of holistic health. Whether you’re navigating depression, managing anxiety, healing from PTSD, or undergoing ketamine treatment, integrating the right supplements into your wellness plan can make a measurable difference. Here are the top 7 supplements for holistic health, supported by science and widely used alongside therapy and integrative medicine.

A list of Supplements You Need To Know

Omega‑3 Fatty Acids (EPA & DHA)

Why it matters: Omega‑3s, especially EPA and DHA, are crucial for brain function. They help reduce inflammation, regulate neurotransmitters, and support emotional resilience.

Scientific insights: Numerous studies have shown a strong connection between high omega‑3 intake and reduced symptoms of depression and anxiety. EPA-rich formulations, in particular, have demonstrated the most consistent mood-enhancing effects.

Recommended dose: 1–2 grams per day of combined EPA and DHA.

Best for: Mood stabilization during therapy and enhancement of ketamine treatment outcomes.

Magnesium (Glycinate, Citrate, L‑Threonate)

Why it matters: Magnesium helps regulate stress, supports neurotransmitter function, and plays a role in sleep and muscle relaxation.

Scientific insights: People with depression and anxiety often have magnesium deficiencies. Magnesium glycinate promotes calm and sleep, citrate is easily absorbed, and L‑Threonate crosses the blood–brain barrier, supporting cognitive function and emotional health.

Recommended dose: 200–400 mg daily.

Best for: Reducing stress and supporting therapy sessions.

Zinc

Why it matters: Zinc is essential for neuroplasticity and hormonal balance.

Scientific insights: Deficiency in zinc has been linked to increased depressive symptoms. Supplementing with zinc has been shown to enhance the effectiveness of antidepressants and reduce anxiety.

Recommended dose: 15–30 mg per day.

Best for: Complementing traditional therapy or ketamine therapy protocols.

Rhodiola Rosea

Why it matters: This adaptogenic herb increases the body’s resistance to stress and enhances energy levels.

Scientific insights: Rhodiola has shown promise in reducing symptoms of fatigue, depression, anxiety, and PTSD. It supports both mental and physical performance under stress.

Recommended dose: 200–600 mg per day, standardized to 3% rosavins.

Best for: Stress resilience, especially for those recovering from trauma or PTSD.

Saffron

Why it matters: Saffron contains mood-lifting compounds that influence serotonin activity in the brain.

Scientific insights: Clinical trials have shown saffron to be as effective as conventional antidepressants for mild to moderate depression. It also helps improve emotional regulation and cognitive clarity.

Recommended dose: 30 mg per day (standardized extract).

Best for: Natural mood support during therapy or ketamine sessions.

L‑Theanine

Why it matters: Derived from green tea, L‑Theanine promotes calm without sedation and enhances mental clarity.

Scientific insights: This amino acid has been shown to reduce stress hormones like cortisol, alleviate anxiety, and improve focus and mood stability—making it ideal for therapeutic environments.

Recommended dose: 100–200 mg per day.

Best for: Enhancing focus and calm before and after therapy.

Acetyl‑L‑Carnitine (ALCAR)

Why it matters: ALCAR supports mitochondrial health and has neuroprotective effects, especially in individuals with depression.

Scientific insights: Clinical studies have shown that ALCAR can provide rapid antidepressant effects, particularly in treatment-resistant depression. It supports brain energy metabolism and helps regenerate nerve cells.

Recommended dose: 500–1,500 mg per day.

Best for: People seeking fast-acting mood improvement and those using ketamine treatment.

How These Supplements Complement Ketamine Treatment and Therapy

Combining nutritional supplements with ketamine treatment and psychotherapy creates a powerful synergy. Here’s how:

  • Neuroplasticity enhancement: Omega‑3s, ALCAR, and magnesium foster brain rewiring—a key aspect of ketamine-assisted therapy.

  • Stress regulation: Rhodiola and L‑Theanine modulate the body’s stress response, reducing anxiety before and after sessions.

  • Emotional stability: Zinc and saffron help regulate mood and support long-term recovery from depression, anxiety, and PTSD.

At Holistic Wellness & Psychiatry, these supplements are often integrated into individualized care plans, helping clients optimize their healing journey through safe, science-backed solutions.
