Omega-3 and other nutrient augmentation

Domain IX · Biomedical, neuro & digital

What it is

Nutrient augmentation is not a psychotherapy. It means adding a nutrient-derived product (an EPA-predominant omega-3 preparation, folate or L-methylfolate, S-adenosyl-L-methionine (SAMe), vitamin D, zinc, N-acetylcysteine (NAC) and similar agents) to standard treatment, mostly to an antidepressant,…

Format

• There is no session protocol for psychotherapists; nutrient augmentation is woven into ongoing therapy. The working sequence below is, built on the guidelines' own steps: confirm the diagnosis and physical health first, use measurement-based assessment, use agents as add-ons to standard treatment,…
• Phase A. Inventory (first sessions, then at every review). Goal: know everything the client takes (prescribed medicines, over-the-counter products, supplements, herbal products, powders, "stacks", fortified drinks) and why. Format: a few minutes in intake and at each formal review. Move on when the…

Who practises it, and how they are trained or regulated

• Phase C. Shared decision support during a trial. Goal: the client understands evidence level, regulatory status and risks, and has agreed with the prescriber how long a trial lasts and how benefit will be judged. A CANMAT presenter suggests agreeing a defined trial period and criteria for judging benefit, as with psychotherapy or medication trials. Format: part of regular sessions. Move on when a trial plan exists.
• Version followed: the WFSBP and CANMAT Taskforce clinician guidelines on nutraceuticals and phytoceuticals (Sarris et al., 2022) as the main reference; the International Society for Nutritional Psychiatry Research (ISNPR) practice guidelines for omega-3 fatty acids in major depressive disorder (Guu et al., 2019) for omega-3; the CANMAT 2023 update for adult depression (Lam et al., 2024) as summarised in a secondary…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• nausea; stacked multi-mineral products; interaction questions (route to pharmacist).
• "waiting for it to kick in" while deteriorating; it is working when the client can name what they would do.
• perinatal mood changes; hypomania; parental pressure; it is working when the relevant specialist has reviewed.
• NAC replacing exposure and response prevention; gastrointestinal effects; use alongside other medicines (route to pharmacist).
• multi-ingredient "mood blends" with undisclosed contents; any serotonergic combination; contraceptive users taking St John's wort.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
