Liquid stevia drops have zero calories and allow precise dosing (1–3 drops). They are steviol glycosides dissolved in water or glycerin. The same meta-analysis evidence (Anker et al., 2019) applies – no significant glycemic effect was found in RCTs.
How should I track Stevia, liquid drops?
When tracking Stevia, liquid drops, measuring by weight on a kitchen scale gives you the most precision. Volume measures vary depending on crystal size and powder density — a heaping spoonful can be double a level one. Research shows visual estimation errors reach 50–200% for calorie-dense foods (Almiron-Roig et al., Appetite 2013), and liquid sweeteners like honey are among the easiest to over-pour. For zero-calorie sweeteners, bulking agents add trace calories (2–4 per packet) — negligible in your daily total. For calorie-containing sweeteners, the scale is essential.
