Common questions

Can a supplement fix my symptom?
Sometimes, if the symptom is driven by a genuine nutrient shortfall. Many symptoms (fatigue, brain fog, hair loss, cramps) are commonly linked to low iron, B12, vitamin D, or magnesium, and correcting a measured deficiency helps. But symptoms have many causes, so the smartest move is to check the relevant biomarkers first rather than guess.
Which deficiencies cause the most symptoms?
Low iron (fatigue, hair loss, restless legs, cold hands), vitamin B12 (brain fog, tingling, low mood), vitamin D (low mood, weak muscles, frequent colds), and magnesium (cramps, poor sleep, anxiety) are the four that show up most often. They are also cheap and easy to test.
Should I test before supplementing?
For anything that could reflect a deficiency, yes. A simple panel (ferritin, B12, vitamin D, magnesium, thyroid) tells you whether a supplement is the right answer. You can upload your results to the bloodwork tool and we'll read the relevant markers.
