Short Summary
Main recommendation: Dr. Hansen's main view: most people who eat a balanced, mostly unprocessed diet do not need dietary supplements, and he recommends discussing any supplement with a doctor before starting. Dr. Mike Hansen notes that the supplement industry is loosely regulated, so product quality, safety, and labeling are not reliably verified, and he cites research suggesting some supplements may carry risks such as kidney stones, GI distress, and liver damage.
Key Points
- Dr. Hansen cites a survey finding that most U.S. adults and a third of children use dietary supplements.
- He personally takes at most one to three supplements: fish oil (omega-3s), vitamin D in winter when sunlight is low, and creatine before gym workouts.
- Omega-3s can also come from food such as salmon, walnuts, chia seeds, hemp seeds, and flax seeds.
- Global supplement sales have grown substantially over the past decade, driven by self-care trends and targeted marketing.
- The FDA does not review dietary supplements for safety and effectiveness before they reach the market; manufacturers are responsible for safety and accurate labeling, which he says many do poorly.
- He says the best health gains come from healthy eating, exercise, stress reduction, and high-quality sleep, and that it's tempting but often unrealistic to think supplements will magically improve health.
Details Worth Noting
- Concrete instructions: Eat a balanced diet built mainly on whole foods, including fruits, vegetables, whole intact grains, legumes such as beans, seeds and nuts, eggs, and lean meats like skinless chicken breast and fish. Take a supplement only if you have a specific likely gap, such as omega-3s or vitamin D, and speak with a doctor before starting any new supplement regimen. Before buying any supplement, do your homework on what it actually does and whether it is high quality.
- Dr. Hansen's own use: fish oil described as burpless, taken for omega-3s; vitamin D only during winter months when sunlight feels insufficient; creatine only before weight training.
- He lists possible risks of overconsumption: kidney stones, gastrointestinal distress, and in some cases liver damage, plus the cost of buying supplements.
- He names probiotics and garcinia cambogia extract as examples of supplements that merit careful research before buying.
Bottom Line
Supplements are generally unnecessary for people eating a varied whole-food diet, and because the industry is weakly regulated, anyone considering one should check with a doctor first.
