Natural Factors Vitamin D3 Drops – unflavoured liquid delivering 25 µg (1,000 IU) of vitamin D3 per drop in a 15 ml bottle.
+ Fully disclosed individual dose for the active ingredient. + One of the more affordable options in its category. + Includes organic flaxseed oil, a minority‑share inclusion among peers. + Vegetarian‑friendly liquid form for easy dosing.
- Contains several allergens: gluten, soy, fish, crustaceans and eggs. - Includes sugar and starch as excipients, which some users may wish to avoid. - Unflavoured, which may be less appealing to those preferring taste.
This product stands out by offering a budget‑friendly, liquid vitamin D3 with a clear 25 µg per‑drop dosage and the uncommon addition of organic flaxseed oil, while also being marketed as dairy‑free. All actives are transparently labelled, but the formulation lists multiple common allergens and added sugar and starch, which could be a drawback for sensitive consumers.
