Vitamins & Minerals at Work
Micronutrients doing their actual chemical job, one step at a time — magnesium clamping ATP so an enzyme will accept it, sunlight starting the vitamin D chain in the skin, vitamin C hydroxylating collagen, parathyroid hormone holding blood calcium inside its narrow band, B12 riding intrinsic factor through the gut, and the vitamin K cycle that warfarin interrupts.
Every page here is a hands-on animated diagram, not a video — press play, slow it down, break the mechanism on purpose, and read the live values in real clinical units. They explain how a process works; they are not medical advice, and the evidence for any treatment lives on the topic pages each animation links into.

Magnesium: The Mineral That Makes ATP Work
Bare ATP is useless — enzymes reject it. Watch magnesium clamp the phosphates and switch it on, plug the NMDA channel, and let a cramping muscle finally let go.
Launch animation →Vitamin D: From Sunlight to Hormone
Fire UVB photons at your skin and follow the molecule through the liver and kidney into an actual steroid hormone that walks into the nucleus and switches genes on.
Launch animation →Vitamin B12's Impossible Journey
Five stages, two carrier proteins, a working stomach, a working pancreas and one specific stretch of gut. Break any link — a PPI, metformin, pernicious anaemia — and absorption collapses.
Launch animation →Vitamin C, Collagen & Why Sailors Fell Apart
Zip three protein chains into the strongest rope in biology — then take the vitamin C away and watch the helix unravel, and old, healed scars split back open.
Launch animation →Calcium Control: PTH, Vitamin D & Your Blood Level
Watch four tiny parathyroid glands defend your blood calcium — pulling it from bone, kidney and gut with PTH and vitamin D — then drop your vitamin D and see PTH climb and quietly rob the skeleton.
Launch animation →Vitamin K, Clotting & How Warfarin Works
Watch vitamin K get recycled to switch on the clotting factors — then block the recycling enzyme with warfarin and see the factors go dark over days, or override it with a plate of greens.
