Vitamin D Testing: dose from data, not guesswork
Vitamin D need varies with skin tone, latitude, body weight and time spent outdoors. What the research says: It behaves like a hormone, influencing calcium handling and immune gene expression. A 25(OH)D blood test is the only way to know whether your dose is too low or already enough. Why it matters: Long-term studies keep pointing back to this as the boring predictor of good outcomes. Collagen crosslinking and joint lubrication respond directly to it. Try this today: test before supplementing and take D3 with a meal containing fat. Do the smallest version today; scale only once it survives a busy week. Boring consistency is the edge nobody advertises.
