🔬 Don't Guess — Test What You Actually Need
At-home lab kits let you check vitamin D, B12, iron, magnesium, cortisol, and more — without a doctor's visit. Results in 3–5 days. Know exactly which supplements your body needs.
Which Vitamins Should You Actually Take?
The supplement industry generates over $177 billion per year globally — yet most people are taking the wrong supplements for their specific needs, or wasting money on ones they don't need. The answer starts with knowing your body.
The Most Common Nutrient Deficiencies in Adults
Studies consistently show that most adults in the US are deficient in at least one key nutrient. The most common are:
- Vitamin D — estimated 41% of US adults are deficient, especially those with limited sun exposure
- Magnesium — over 50% of Americans don't meet the daily requirement through diet alone
- Vitamin B12 — nearly 40% of adults have suboptimal levels; vegans and over-50s are at highest risk
- Omega-3 — most Americans eat far too little DHA and EPA due to low fish consumption
- Iron — affects up to 30% of premenopausal women
Supplements by Life Stage
Ages 18–30: Focus on foundational nutrition — Vitamin D, Omega-3, B12, and Magnesium. Women in this group should add Iron and Folate.
Ages 30–50: Add CoQ10 for cellular energy, Collagen Peptides for joints and skin, and Ashwagandha for stress management. Men can add Zinc for testosterone support.
Ages 50+: Prioritize Calcium (women), CoQ10 (especially on statins), Vitamin K2 with D3, Saw Palmetto (men), and a comprehensive B-Complex. Lion's Mane for cognitive support gains relevance here.
The Lab Test First Approach
The smartest supplement strategy isn't guessing — it's testing. A simple at-home panel from Everlywell or a clinical test from Labcorp can confirm your exact deficiencies, saving you money on supplements you don't need and ensuring you address the ones you do. Many users find that just 2–3 targeted supplements based on lab results outperform a handful of random additions to their routine.
