I much prefer a sublingual drop Vitamin D over capsule form due to its bioavailability and the quick delivery system into my bloodstream. Especially living in the Northern Hemisphere and the Pacific Northwest during the fall and winter it can be quite challenging to keep mood and energy levels in balance. So a Vitamin D supplement can be super beneficial during the colder darker months But another factor is QUALITY of the supplement I need to know if something actually works and that I can trust the brand I’m using. Not all supplements are created equally or use a good ingredient source What I like about Triquetra s Vitamin D is that it s sourced from sun -grown algae from a farm they work directly with in Utah. It’s plant based and bioavailable
