Functional benefits
Does not promote dental caries
FDA confirms D-tagatose is eligible under 21 CFR 101.80 when food criteria are met.

Increases colonic butyrate (fermentation)
Venema et al.: healthy adults 7.5–12.5 g/d for 2 weeks; butyrate up in vitro / model systems; high dose raised lactobacilli in men. Prebiotic-like — display-only; not an ISAPP-certified prebiotic claim.

Risks & side effects
Osmotic GI discomfort at higher intakes
caution
75 g caused diarrhoea, nausea or bloating in every participant; at 10–30 g only 3 of 10 people with type 2 diabetes had mild symptoms. In screening for another trial about a third of 73 young men had diarrhoea at 30 g (Buemann 2000, via VKM / FSANZ summaries). Not a medical diagnosis. Scored: −7 on Everyday Health, Diabetic-friendly and Minimally processed — no symptom-free single dose on file, so the 75th percentile of rows with one (missing is not clean).
