Morning with breakfast. Vitamin D3 is fat-soluble — it requires dietary fat for absorption. Taking D3 with a fat-containing meal increases absorption 32-50% compared to taking it on an empty stomach or with a low-fat meal. Morning is preferred because: (1) Vitamin D may slightly suppress melatonin production (the sleep hormone) — taking it late in the day could theoretically disrupt sleep in sensitive individuals. (2) It aligns with natural circadian rhythm — your body produces vitamin D from morning sunlight. (3) Consistency matters more than timing — take it whenever you will remember daily. Practical takeaway: Take D3 with your largest meal of the day (which typically has the most fat). If you eat breakfast with eggs, avocado, or yogurt — that is perfect. Pair with K2 (MK-7) for optimal calcium direction to bones.
