Natural Factors SunVitamin D3 delivers 2500 IU of bioavailable vitamin D3 to support strong bones and immune function. This high-potency formula helps prevent vitamin D deficiency while supporting calcium absorption and bone mineralization. The cholecalciferol form matches what your body naturally produces.
Why It Works
SUPERIOR ABSORPTION: Cholecalciferol (D3) raises blood levels more effectively than synthetic D2 forms.
BONE STRENGTH: Enhances calcium and phosphorus absorption for proper bone mineralization and density.
IMMUNE FUNCTION: Supports both innate and adaptive immune responses at the cellular level.
What's Inside
Each softgel contains 2500 IU vitamin D3 in organic flaxseed oil for optimal absorption. Made in Canada with gelatin softgels.
Why we carry it: Natural Factors consistently delivers the potency and purity standards our customers expect from vitamin D3.
Take 1 softgel daily or as directed by a health care practitioner. Take with adequate calcium intake. Consult a health care practitioner for use beyond 6 months.
This one is a favorite for me for so long! I like the higher concentration it has compared to most other product. The only thing I would say is that the dosage writing on the packaging is far from being the therapeutic dosage needed. (Blame health Canada...)
Taking it on a therapeutic dosage (50iu/kg of body weight) has helped me sooo much with joint pain and chronique inflammation -headache, menstrual pain, muscle pain-. After my first week, I felt my body so much younger (I was only 35, feeling 80). It was the only supplement I took then and I was amazed of the effect. Since then, I learned that D3 NEEDS to be taking along with a team of nutrients called cofactors, so I paired it with 400mg magnesium and a good quality multivitamine. These are my absolute everyday low-cost essential now to manage chronique inflammation.
