Description
Natural Factors SunVitamin D3 provides a convenient, high-potency dose of vitamin D as cholecalciferol to help prevent vitamin D deficiency, and for the development and maintenance of strong bones and teeth. Vitamin D3 is the natural form of this vital nutrient and is most effective at raising blood levels of active vitamin D.
Vitamin D plays a key role in the absorption of calcium and phosphorus, two minerals that are vital for proper bone mineralization and turnover. Vitamin D is also required for the body’s innate and adaptive immune responses.
Each tablet or softgel delivers a single 2500 IU (62.5 mcg) dose of vitamin D3 for convenient maintenance of adequate vitamin D levels in people who are deficient due to a low dietary intake, minimal sun exposure, or inadequate absorption. When combined with an adequate calcium intake, a healthy diet, and regular exercise, vitamin D3 helps reduce the risk of developing the brittle, weak bones of osteoporosis.
SunVitamin D3 2500 IU is certified non-GMO and is available as tablets or softgels in multiple sizes. This formula contains no artificial colours, preservatives, sweeteners, and is suitable for use during pregnancy and while nursing an infant.
Frequently Asked Questions
What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
