Description
Big Friends children’s vitamins are back in a big way, and now better than ever. Natural Factors Big Friends Liquid Vitamin D3 offers a convenient way to ensure all children, from infants to 13-year-olds, get the vitamin D they need to support healthy development of bones and teeth.
Kids will love Big Friends Liquid Vitamin D3, which comes with a baby-safe shaker cap for accurate dosing. The neutral-tasting, oil-based formula ensures excellent absorption and can be taken directly or mixed into food. The liquid form is also well suited to breastfed infants.
Known as the “sunshine vitamin”, this essential nutrient is usually synthesized by the skin through sun exposure. However, many experts recommend supplemental vitamin D for children of all ages as decreased sun exposure puts many at risk of vitamin D deficiency.
Vitamin D is vital for the absorption and use of calcium and phosphorus, and supports the nervous system. Vitamin D3 is the natural form needed by the human body and is much more effective at raising active D3 levels than vitamin D2.
Parents of young children today may fondly recall the Big Friends name from their own childhood, and while Liquid Vitamin D3 is new to the family, Natural Factors’ commitment to quality is as steadfast as when Big Friends was first introduced over 50 years ago.
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.
