Nutrition: Practical ways to use supplements and get more from food

Want better energy, fewer headaches, or steadier blood sugar? Small nutrition moves often beat flashy supplements. Eat real food first, then use targeted supplements to fill gaps. Below are simple, useful steps you can try today and the safety checks you shouldn’t skip.

Choose supplements that actually help

Start with the problem you want to solve. For low energy or frequent headaches, riboflavin (vitamin B2) has real evidence helping some people—look for 400 mg/day clinical doses only when advised by a clinician. If you’re low on vitamin D, a blood test will show it; common doses range from 1,000–4,000 IU daily depending on results. Magnesium can help breathing and muscle relaxation, but the form matters: magnesium glycinate is gentler on the stomach than magnesium oxide.

Watch the riskier products. Gossypol and some herbal extracts like cnidium or purple loosestrife have niche uses and safety questions. Read the research summary in any product listing and avoid high-dose herbal blends unless a doctor follows you. If you’re pregnant or planning pregnancy, note that drugs like metformin have specific effects on offspring development studied in recent research—always check safety with an obstetrician.

How to pick and use supplements safely

Look for third-party testing (USP, NSF, ConsumerLab). That helps reduce the odds of contamination and wrong doses. Check labels for exact amounts, active form (e.g., methylcobalamin vs. cyanocobalamin for B12), and expiration date. Start low: try a lower dose for a week to watch for side effects. Take fat-soluble vitamins (A, D, E, K) with a meal. Spread iron doses away from calcium, and be cautious mixing supplements with prescription meds—some diabetes drugs, antibiotics, and antidepressants have known interactions.

Get basic labs before long-term supplementation: vitamin D, B12, iron studies, and a basic metabolic panel if you’re taking anything that affects kidneys or liver. Track symptoms in a simple note app: sleep, mood, energy, bowel habits. That record helps you and your clinician decide whether to keep a supplement.

Small changes add up: improve one meal a day, add one test, and focus on quality over quantity in your supplement shelf. If something promises dramatic results fast, treat it with healthy suspicion and ask a clinician before trying it.
