Both monk fruit and stevia are natural, zero-calorie sweeteners and are safe for long-term use. Monk fruit is generally considered slightly better tolerated as it has no bitter aftertaste that some people notice with stevia. For someone on
thyroid medication like you, both are fine. When buying monk fruit, look for pure monk fruit extract products without added erythritol or fillers if you want the cleanest option.
Next Steps
Either sweetener can be used long term in moderation. Choose based on your taste preference. Please consult me directly on Practo for a detailed evaluation.
