What to look for in a Vitamin D3

Vitamin D3 supports bone, immune, and muscle health and is most useful when you have limited sun exposure, darker skin, or test low on a 25(OH)D blood test.

Quick checklist

• Strength: 1000–5000 IU daily is typical for adults; confirm a target with your doctor.
• Form: softgels with a carrier oil absorb better than dry tablets.
• K2 pairing: many D3 supplements are paired with K2 (MK-7) for bone and cardiovascular balance.
• Allergens: check for soy, gluten, or lanolin-free options if you need them.
