Start from gaps, not products
The best routine begins with what you actually need, not what's trending. Look at your diet, life stage, and any diagnosed deficiency to identify real gaps (see who's at risk and food-first). For many people, that's a short list — or nothing [2].
Keep it minimal
More products mean more cost, more chances for interactions, and more overlap. A focused routine — a few targeted items — beats a crowded cabinet [1].
Time it sensibly
- Fat-soluble vitamins (A, D, E, K) and fish oil absorb better with a meal containing fat.
- Minerals that compete (calcium, iron, zinc) are best spaced apart (see [minerals that compete](/learn/minerals-that-compete-for-absorption)).
- Separate minerals and fiber from medications by a few hours (see [timing around medications](/learn/timing-supplements-around-medications)).
- Stimulant or 'energy' products belong earlier in the day so they don't disrupt sleep.
Build in safety checks
- Add up each nutrient across all products and stay under the [upper limits](/learn/upper-intake-levels-explained).
- Review the list with a clinician or pharmacist, especially if you take medications (see [when to talk to a doctor](/learn/when-to-talk-to-a-doctor-about-supplements)).
- Choose [third-party-tested](/learn/supplement-certification-seals-compared) products.
Make it stick — and revisit it
- Anchor doses to habits (with breakfast, by your toothbrush) and store them [properly](/learn/how-to-store-supplements).
- Reassess every few months: are you still in a gap? Is it [working](/learn/how-to-tell-if-a-supplement-is-working)? Drop anything that isn't earning its place.
Practical guidance
Keep it small, targeted, well-timed, and reviewed. A two-item routine you take consistently and safely beats a ten-item one you can't keep track of.
