Research Promise: At LifeSource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. In addition, we reference reviews from 39 leading health organizations and insights from 20 top global universities to ensure our guidance aligns with credible science.*
Clinically Studied Benefits (with research)
• Zero-calorie sweetness — High-purity steviol glycosides provide intense sweetness without calories. (NIH/PMC — Shah A, 2018)
• No acute impact on blood glucose — Human studies report stevia sweeteners do not raise post-meal glucose in healthy adults. (NIH/PMC — Anton SD, 2010)
• Supports calorie management — Replacing sugar with non-nutritive sweeteners can reduce daily energy intake in trials. (NIH/PMC — Shah A, 2018)
• Oral/dental friendly — Stevia does not contribute to caries; in vitro and human data support non-cariogenic profiles. (NIH/PMC — Brambilla E, 2018)
• Metabolic support (adjunct) — Early clinical evidence suggests potential improvements in glucose tolerance/insulin dynamics. (NIH/PMC — Gupta E, 2022)
• Blood-pressure support (preliminary) — Stevioside has been studied for modest BP effects in adults with mild hypertension. (NIH/PubMed — Hsieh MH, 2003)
• Weight-management aid — Calorie displacement from sweetener substitution is associated with small weight effects in some trials. (NIH/PMC — Shah A, 2018)
• Flavor versatility & acceptance — Modern high-purity Reb-A/Reb-M systems reduce bitterness with good sensory acceptance. (NIH/PMC — Shah A, 2018)
• Suitable for keto/low-carb — Non-glycemic, zero-carb sweetener appropriate for carbohydrate-restricted patterns. (NIH/PMC — Anton SD, 2010)
• Generally well-tolerated — Human studies report good GI tolerance at typical usage levels. (NIH/PMC — Shah A, 2018)
Additional Studies Showing Promising Benefits*
• Insulin dynamics — Exploratory work suggests stevia may influence insulin secretion/sensitivity in select contexts. (NIH/PubMed — Hsieh MH, 2003)
• Antioxidant potential — Steviol glycosides/polymers show antioxidant properties in human-relevant models. (NIH/PMC — Lemus-Mondaca R, 2021)
• Appetite & cravings (emerging) — Non-nutritive sweeteners can aid sugar-reduction strategies in diet plans. (NIH/PMC — Rogers PJ, 2016)
University Studies
• Metabolic research centers — Human trials on stevia’s post-prandial glucose and energy-intake effects. (NIH/PMC — Anton SD, 2010)
• Nutrition & appetite labs — Non-nutritive sweeteners and body-weight outcomes across controlled studies. (NIH/PMC — Rogers PJ, 2016)
• Dental schools — Caries risk and oral ecology with stevia vs. fermentable sugars. (NIH/PMC — Brambilla E, 2018)
• Food science programs — Taste acceptance and bitterness-mitigation strategies for high-purity stevia. (NIH/PMC — Shah A, 2018)
