Big Friends children’s vitamins are back in a big way, and now better than ever. Big Friends Liquid Vitamin D3 from Natural Factors 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.

Children 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 low vitamin D status.

Vitamin D is vital for the absorption and use of calcium and phosphorus, and supports the nervous system, and immune function. 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 20 years ago.
