Cover the basics first
Most healthy adults have no supplement they must take every day. Cover food variety, sleep, and movement first; then, if anything, fill one evidence-based gap — vitamin D for a largely indoor life, or omega-3 if fish is rarely eaten — rather than a broad stack.
Supplements sit below these fundamentals. The order matters.
Everyday Basics readers are general healthy adults without the extra demands of heavy training or a restrictive diet. Unlike other Types, that means ordinary food can usually meet almost every nutrient. The real difference here is that the decision starts from your own food record — belonging to this group is not itself evidence of a gap.
Belonging to this group does not mean a gap exists. Each one separates the cause, the food-first fix, and when a supplement actually helps.
Not everything is equal. These are grouped by evidence and practicality for this audience.
Supports bone and muscle and corrects a shortfall when sun and diet are low.
Supplies EPA/DHA for people who rarely eat fish.
A temporary aid when dietary fiber is low during a transition.
Delivers small amounts of many micronutrients, with little added benefit on a varied diet.
Cooks daily but repeats the same few dishes.
Relies on convenience meals and often misses fiber and vegetables.
Gets little sun, e.g. working from home.
Typical timing: Usually with breakfast. Only steps with a reason are included.
Hold off on supplements and log meals for one to two weeks to assess variety. Fix food, sleep, and movement first.
Pick one consistent candidate gap (e.g. vitamin D for indoor life) and trial a single-ingredient product as labeled.
Supplement only symptom- or test-based gaps, and periodically review overlap, upper limits, and cost.
For healthy adults the main safety issue is not deficiency but excess and duplication. Check that totals across products stay under upper limits and that fat-soluble vitamins and minerals do not stack.
Products are a starting point — check the priorities above first.
Cover the everyday basics
| Multivitamin | 1 serving / day | After breakfast |
| Vitamin D | 1,000–2,000 IU / day | With a meal containing fat |
| Fish oil (Omega-3) | 500–1,000 mg EPA+DHA / day | After dinner |
No. It is not required when a varied diet meets needs. Use a food record to find a specific candidate gap and, if needed, choose a single-ingredient product.
Start with food variety, sleep, and activity — not a product. If your life is mostly indoors, vitamin D is often the first thing to consider.
No. Audience labels do not diagnose a gap. Start with the food-first priorities and assessment questions in this guide, then supplement only a plausible or confirmed gap.
