Vitamin D3 200,000 IU + K2 Softgel

Dr. Harley's Vitamin D3 200,000 IU + K2 is a high-strength, single-dose formulation containing vitamin D3 as cholecalciferol together with vitamin K2 as MK-7.

Vitamin D helps the body absorb calcium and is required for normal bones, muscles, nerves and immune function. Vitamin K contributes to normal blood clotting and healthy bones.

Because each softgel contains 200,000 IU of vitamin D3, this product is not intended for routine daily self-supplementation. It should only be used when recommended by a qualified healthcare professional, usually following clinical assessment or vitamin D testing.

Excess vitamin D can raise blood-calcium levels and may cause nausea, weakness, excessive thirst, frequent urination, kidney stones, irregular heartbeat, kidney damage, or other serious complications.

Directions for Use :

Take one softgel as a single dose only when prescribed or specifically recommended by a qualified healthcare professional.

Take it with or immediately after a meal containing some dietary fat.
