Thera-D® 2000 Vitamin D Supplement (Ships from the US, arrives in 11-14 days)

Independently tested and certified. Thera-D is tested and certified by NSF® International for content accuracy and purity, so you know exactly what you’re getting. Flexible dosing. Thera-D is available in three different doses to meet your individual vitamin D needs: 50 mcg (2,000 IU), 100 mcg (4,000 IU), and 150 mcg (6,000 IU). Quality you can trust. Thera-D is manufactured in the USA in a cGMP compliant facility.

Thera-D contains vitamin D3, the same type of vitamin D produced in your skin after sunlight exposure. Prescription vitamin D typically contains vitamin D2, the plant form of vitamin D. When produced commercially, it is made from yeast.

Your body metabolizes vitamin D3 more efficiently than vitamin D2, and vitamin D3 supplementation is less likely to result in toxicity.* Studies have shown that daily vitamin D3 is two to three times more efficient than high-dose weekly or monthly vitamin D2.* Vitamin D3 is considered the superior supplemental form of vitamin D.*

Think of vitamin D like your body’s MVP. Vital for heart, immune, and bone health, vitamin D plays huge roles in keeping your body healthy.* Research also shows that maintaining a healthy vitamin D level is important for both male and female fertility.*

Research suggests that doses between 50 mcg (2,000 IU) and 100 mcg (4,000 IU) are both safe and effective at maintaining healthy vitamin D levels.* Individuals with higher weights, those that take medications that affect vitamin D metabolism, or those that have difficulty absorbing vitamin D may need even higher amounts of vitamin D each day.* Talk with your healthcare provider to find out how much vitamin D you need each day.
