Understand the basics

With supplements: start conservative, check interactions, and prioritise food + basics first.

Educational info only — not medical advice.

Why it matters

  • Supplements can help a targeted gap, but they rarely fix a lifestyle problem on their own.
  • Taking multiple new supplements at once makes it hard to know what’s helping (and increases the risk of side effects).

Common causes

  • Chasing “quick fixes” for fatigue or sleep rather than addressing schedule, stress, and food basics.
  • Undertaking big stacks without checking interactions (especially with medication).

First steps (no spend)

  • Focus on the foundation for 2–4 weeks: consistent wake time, daily light, protein + fibre with meals, and regular movement.
  • If you suspect deficiency, consider a clinician-led approach rather than guessing doses.

Start here

  • Start with one thing at a time so you can tell what helps.
  • Check interactions if you’re pregnant, medicated, or managing a condition.
  • Aim for consistency and basics (sleep, diet, movement) first.

What to look for

  • Transparent ingredients and sensible dosages.
  • Reputable brands with basic testing/quality statements.
  • A plan to reassess — supplements aren’t always forever.

Avoid

  • High‑dose ‘all-in-one’ stacks with lots of extras.
  • Claims that sound medical or guaranteed.
  • Buying multiple products at once and guessing what worked.

How we evaluate

  • Clear reason to take it (goal, deficiency risk, diet context).
  • Dose and form are straightforward, with transparent labelling.
  • Avoiding inflated claims and proprietary blends when possible.

When it’s not worth buying

  • If you take prescription medications: check for interactions first.
  • If you’re pregnant/breastfeeding or have chronic conditions: get clinician advice.
