Vitamin D3


Vitamin D, recognized as a hormone, is integral to numerous body systems and physiological processes. Globally, it is among the most prevalent nutrient deficiencies, with nearly 40% of Canadians exhibiting insufficient or deficient levels. Vitamin D plays a critical role in supporting healthy immune function, potentially reducing the risk and severity of infections, especially respiratory tract infections, particularly in individuals susceptible to infection. Recent studies have established a connection between lower vitamin D levels and an elevated risk of cardiovascular diseases, including hypertension, peripheral vascular disease, and coronary artery disease.

This vitamin is essential for the absorption of dietary calcium and crucial for bone health and muscle strength. Vitamin D's influence extends to overall physical fitness and performance, with lower levels associated with frailty, particularly in older adults. Clinically relevant supplementation has demonstrated a well-established reduction in osteoporotic fractures. With receptors for vitamin D present in essentially every tissue in the body, its importance is challenging to overstate. Many practitioners recommend supplementation to achieve blood levels of 50–80 nmol/L for 25-OH-vitamin D. This target often necessitates daily doses of 1000–2000 IU and higher amounts for individuals with common genetic variants affecting vitamin D metabolism.


  • Vitamin D3 (cholecalciferol) is likely more effective at restoring blood levels than the D2 form (ergocalciferol)
  • Cholecalciferol is also shown to increase the proportion of the active form of vitamin D versus ergocalciferol
  • 2500 IU of vitamin D per softgel allows for easy daily dosing
  • Easy-to-swallow and highly bioavailable softgel
  • In a base of organic flaxseed oil for improved intestinal absorption

Medicinal Ingredients

Each Softgel Contains:

Vitamin D3 (Cholecalciferol) 2500 IU (62.5 mcg)


Non-Medicinal Ingredients

Softgel (gelatin, glycerin, purified water), organic flaxseed oil.


Recommended Adult Dose (18 years old and above): 1 softgel per day or as directed by a health care practitioner. To be taken with an adequate intake of calcium. Consult a health care practitioner for use beyond 6 months.


Consult a health care practitioner prior to use if you are pregnant or breastfeeding, if you have kidney disorders, if you take other vitamin D supplements, multivitamin supplements containing vitamin D or products containing vitamin D analogues, or any prescription medications including antacids, anticonvulsants, digoxin, cholestyramine, colestipol, mineral oil, steroids, statins, or thiazide diuretics. 15–20 mcg (600–800 IU) of vitamin D per day is adequate for most individuals. Consult a health care practitioner to determine if you would benefit from additional vitamin D before taking this product. Do not use this product if you have hypercalcemia and/or hypercalciuria. Stop use and consult your health care practitioner if weakness, fatigue, drowsiness, headache, lack of appetite, dry mouth, metallic taste, nausea, vomiting, vertigo, ringing in the ears, lack of coordination, and muscle weakness (which are early symptoms of hypercalcemia) occur, or if you have any other side effects. Keep out of reach of children.


Contains no artificial colours, preservatives, or sweeteners; no dairy, starch, sugar, wheat, gluten, yeast, soy, corn, egg, fish, shellfish, salt, tree nuts, or GMOs.


Caution is advised for individuals with a hypersensitivity to any of the ingredients, and those with lymphoma, tuberculosis, hypercalcemia, or renal impairment. Individuals with sarcoidosis should also consult their health care provider. While previously a relative contraindication, sarcoidosis activity is correlated with hypovitaminosis D as suggested by more recent data and un-supplemented individuals are at a greater risk for hypercalcemia.

Drug Interactions

When taken with a thiazide medication (diuretic), may increase the risk for hypercalcemia.  Also, vitamin D may improve insulin sensitivity and lower blood pressure, requiring a reduction in dosage of hypertension and/or diabetic medications.
