Body Map
Upload a photo of any supplement, vitamin, or herbal label. I'll read the ingredients, check reputable medical sources, and light up the parts of the body where there is actually credible evidence each ingredient acts. If a "brain support" supplement doesn't light up the brain, you know, without reading a word.
Tap any ailment patch to learn what ingredients act on that system. Or upload a label to light them up at once.

When the gut isn't the way
Body Map shows where supplements act once they're in your body. But not every nutrient or medication enters through the supplement aisle. These are the real medical routes you may hear about in family or hospital conversations.
- Oral (pills, food, drink): the supplement-aisle default. Limited by gut absorption, which can fail in malabsorption, severe deficiency, or ongoing loss.
- Sublingual (under the tongue): bypasses the stomach. Used for some B12 forms and certain medications.
- Intramuscular injection: bypasses the gut entirely. Standard for B12 in pernicious anemia, vitamin K at birth, and most vaccines.
- Intravenous (IV) infusion: "intravenous" means into a vein. A small needle or catheter is placed in a vein, usually in the arm, and fluid or medication flows directly into the bloodstream from a bag on a stand. IV iron for severe iron deficiency, IV antibiotics for serious infections, IV vitamin C as an investigational adjunct (not a cancer cure).
- Total Parenteral Nutrition (TPN): a complete diet (glucose, amino acids, lipids, vitamins, minerals, and electrolytes) delivered through a longer-term IV line that runs into a large vein near the heart. Used when the gut cannot absorb at all (severe Crohn's, short bowel, cancer treatment complications, post-surgical recovery). When someone says a relative is being "fed by IV," this is usually what they mean. It is a full diet flowing through the veins, not a sugar-water drip.
- Blood transfusion: red blood cells and the iron they carry delivered straight into circulation. Used for severe anemia, surgical blood loss, and transfusion-dependent conditions.
