Overview
Carlyle Vitamin D3 Liquid Drops deliver 5000 IU (125 mcg) of vitamin D3 per dose in a 2 ounce bottle. The formula is unflavored, vegetarian, non-GMO and gluten free, meant for adults who want a swallow-free way to take vitamin D.
Liquid drops let you adjust dose volume rather than being locked into a fixed tablet strength, and they can be added to water or food since the formula is unflavored. That makes this a fit for anyone who has trouble swallowing pills or wants to titrate their intake gradually.
- 5000 IU (125 mcg) vitamin D3 per dose
- 2 fluid ounce liquid bottle
- Vegetarian, non-GMO, gluten free
- Unflavored formula
Who it's for
Adults who prefer drops to capsules or tablets, including vegetarians who want to avoid gelatin-based softgels. Not the pick for someone who wants a flavored liquid or a set daily gummy or tablet routine.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vegetarian and non-GMO formula
- Dropper allows flexible dosing
- No swallowing a tablet
- Unflavored liquid may not appeal to everyone
- No stated number of servings per bottle
Performance notes
Each dose is measured with the bottle's dropper, so intake scales with however many drops you use rather than one fixed tablet size. Being unflavored, it mixes into a drink or food without adding taste, and the 2 ounce bottle is sized for regular, ongoing use rather than a single course.
