Your guide to vitamins & supplements

Some of the most commonly under-consumed nutrients include magnesium, vitamin D, B vitamins (particularly B12 and folate), and omega-3 fatty acids. These nutrients are involved in processes as fundamental as cellular energy production, immune health, and nervous system function.

Food should always come first. Whole foods provide nutrients in forms the body recognizes, along with fiber and other compounds that supplements can't replicate. That said, supplements can help fill gaps that diet doesn't consistently cover, especially for nutrients that are difficult to obtain in reliable amounts from whole foods alone.

NSF Certified for Sport® means a product has been third-party tested for label accuracy, contaminants, and banned substances. It's one of the more stringent independent certifications in the supplement industry.

Look for bioavailable forms of key ingredients, third-party testing, and a formula built around ingredient synergy rather than just a long list of isolated nutrients.

Fat-soluble vitamins (A, D, E, and K) are stored in body fat and the liver. Water-soluble vitamins (the B vitamins and vitamin C) aren't stored in the body and need to be replenished regularly through diet or supplementation.

A well-formulated greens supplement built around nutrient synergy can cover much of the same ground as a multivitamin, often alongside additional support like probiotics or digestive enzymes. The most useful comparison is what each product actually delivers (in what forms, and at what amounts) rather than the category label alone.

This varies by individual, but B vitamins, vitamin D, magnesium, and omega-3 fatty acids are among the nutrients most commonly under-consumed and most foundational to everyday function, from energy metabolism to immune health.

Internal changes aren't always felt right away. Because supplementation works by supporting the body's normal processes over time, many people notice gradual shifts in energy, digestion, or general well-being over weeks rather than days, particularly with consistent daily use.
