Q. How is Thera-D different from prescription vitamin D?
Thera-D contains vitamin D3, the same type of vitamin D produced in our skin after exposure to sunlight. Prescription vitamin D contains vitamin D2, the plant form of vitamin D. When produced commercially, it is made from yeast.
Our bodies metabolize vitamin D3 more efficiently than vitamin D2, and vitamin D3 supplementation is less likely to result in toxicity. Recent studies have shown that daily vitamin D3 is 2 to 3 times more efficient than high-dose weekly or monthly vitamin D2. For these and other reasons, vitamin D3 is considered to be the superior supplemental form of vitamin D.
Q. What is the difference between the Thera-D programs?
Rapid Repletion - for quick repletion to a normal vitamin D level, and then maintenance of that level. Begins with one shipment of Thera-D 4000, followed by ongoing shipments of Thera-D 2000.
Thera-D 2000 - for normal or slightly low vitamin D levels. This program provides a maintenance dose of 2,000 IU per day.
Thera-D 4000 - for low (insufficient) vitamin D levels, or when a doctor has recommended an ongoing higher dose of vitamin D. This program provides an ongoing daily dose of 4,000 IU.
Thera-D 6000 - for very low (deficient) vitamin D levels, or when a doctor has recommended an ongoing higher dose of vitamin D. This program provides an ongoing daily dose of 6,000 IU.
