Our Prenatal DHA is made from tank-grown algae removed from external toxins commonly found in the ocean. DHA (docasahexaenoic acid) is an omega-3 fatty acid that plays a key role in the development of eye and nerve tissue in fetuses and babies. This product is perfect to safely support mom and baby during early development. Freshfield is a Canadian brand that operates through the lens of environmental protection. For every bottle purchased, double as much plastic is removed from the environment as was generated through our packaging and we also ensure the entire process is certified carbon neutral.
