Why Vitamin D Matters
Vitamin D is sometimes called the “sunshine vitamin.” Many people don’t get enough due to limited sunlight, indoor lifestyles, or diet gaps. This section explores toxin-free ways to support healthy vitamin D levels through sunlight, food, and clean supplements.

Vitamin D Q&A + Tips
Natural Sources
Sunlight → Fairer skin may need ~10–20 minutes of midday sun several times a week, while darker skin may need longer (30–60 minutes).
Foods → Cod liver oil, fatty fish (salmon, sardines), egg yolks, and fortified foods.
Supplements → Vitamin D3 (cholecalciferol) is generally considered more effective than D2. Pairing with K2 is often recommended in clean supplements.
Absorption Tips
Take vitamin D with a meal that contains fat for best absorption.
Many people choose to take it in the morning or midday to align with natural sunlight exposure.
Consistency matters more than exact timing.
NIH Recommended Intakes (per day, assuming minimal sun)
Infants (0–12 months): 400 IU (max 1,000 IU)
Children (1–18 yrs): 600 IU (max 2,500–3,000 IU)
Adults (19–70 yrs): 600 IU (max 4,000 IU)
Adults 71+: 800 IU (max 4,000 IU)
Pregnant & breastfeeding women: 600 IU (max 4,000 IU)
Higher amounts are sometimes suggested if blood levels test low, but this should be guided by professional advice.
Vitamin D Q&A
How do I know if my vitamin D might be low?
The best way to know is through testing. A 25-hydroxy vitamin D (25(OH)D) blood test is the standard measurement.
What kind of test should I ask for?
Request a 25-hydroxy vitamin D (25(OH)D) blood test. At-home blood spot kits are also available from reputable labs.
When is the best time to take vitamin D supplements?
Because it’s fat-soluble, take vitamin D with a meal that includes healthy fats like avocado or olive oil. Morning or midday often works well.
Should I pair vitamin D with other nutrients?
Yes — vitamin D often appears in blends with Vitamin K2 and magnesium, which work together in the body’s natural processes.
