Food First, Then Supplements
September 18, 2026

Five nutrients worth understanding, what each one does, and how to get more of it from your plate before you reach for a bottle.
I am going to say something a little odd for someone who works with supplements every day.
Supplements are not the foundation. Food is.
Supplements are there to fill gaps. They are useful, sometimes they matter a great deal, and they still do not replace what happens on your plate. So before we talk about what to take, let us talk about what these nutrients actually do and where to find them in food.
Magnesium
Magnesium supports muscles, nerves, sleep, relaxation, and energy production. It is involved in hundreds of processes in the body.
Something most people do not know: there are more than ten common forms of magnesium, including glycinate, citrate, malate, threonate, taurate, chloride, and oxide. They behave differently in the body, which is why one person does well on a form that upsets someone else.
Food first: Pumpkin seeds are one of the richest everyday sources. Spinach, almonds, avocado, and dark chocolate are good ones too.
Vitamin D with K2
Vitamin D supports the immune system, bones, muscles, and normal cell function. K2 works alongside it to support how your body handles calcium. They are a team, which is why you often see them together.
Food and lifestyle first: Your skin makes vitamin D from sunlight. Wild-caught fatty fish and egg yolks are food sources. K2 shows up in natto, some cheeses, egg yolks, and certain animal foods.
Omega fatty acids
These support the brain, heart, eyes, cell membranes, and a healthy inflammatory response.
There are different families of dietary fats: omega-3, omega-6, and omega-9. Inside the omega-3 family are ALA, EPA, and DHA. Your body can convert some ALA into EPA and DHA, but that conversion is limited, which is why the food sources matter.
Food first: Wild-caught fatty fish. Sardines, salmon, mackerel, herring, and anchovies are naturally rich in EPA and DHA.
B vitamins
The B vitamins support energy production, brain and nervous system function, red blood cell formation, and normal metabolism. There are eight of them. They have individual jobs and they also work together, which is why a complex often makes more sense than chasing one.
Food first: Nutrient-dense whole foods. Meat, liver and other organ meats, eggs, wild-caught fish, poultry, leafy greens, and nutritional yeast. B12 is concentrated in animal foods.
Trace minerals and electrolytes
Minerals and electrolytes support hydration, fluid balance, muscles, nerves, and normal cell function.
Here is the part that surprises people. Hydration is not only about how much water you drink. Your body also relies on sodium, potassium, magnesium, chloride, calcium, and phosphate, plus trace minerals. You lose water and electrolytes every day through sweat, urine, and ordinary body processes.
Food first: A variety of whole foods. Meat, wild-caught seafood, eggs, vegetables, fruit, nuts, and seeds. Salt your food appropriately. Unsweetened coconut water is an easy food-based source of potassium.
Not ready for all of that?
That is completely fine, and honestly it is most people.
If taking several separate supplements is not realistic for you, a quality multivitamin is a reasonable place to start. I prefer individual nutrients because they can be matched to what a body actually needs. But a multi you take beats a perfect plan you abandon in two weeks.
Keep it simple: Food first, supplements second, personalize from there.
I do not want anyone reading this and thinking everyone needs to take all five. The point is to understand what these nutrients do, why your body needs them, and how to get more from your food. Supplementation is support on top of that foundation.
