Energy & Fatigue (4)
- A Randomized Open-Label, Observational Study of the Novel Ketone Ester, Bis Octanoyl (R)-1,3-Butanediol, and Its Acute Effect on Ăź-Hydroxybutyrate and Glucose Concentrations in Healthy Older Adults
PubMed ID: 39985761
Dose‑dependent ketosis in older adults with higher dose lowering post‑meal glucose—supports steadier energy availability.
- Defining metabolic migraine with a distinct subgroup of patients with suboptimal inflammatory and metabolic markers
PubMed ID: 36882474
Responder subgroup had rises in endogenous BHB and major CRP reductions with clinical benefit in migraine — suggests brain metabolic/anti‑inflammatory support in responders.
- Substrate Oxidation Does Not Influence Middle Distance Running Performance: A Randomized Controlled Crossover Trial
PubMed ID: 40944160
Pre‑race LCHF vs HCLF changed RER and fat oxidation markedly — demonstrates substrate switching relevant to flexible use.
- Tolerability and Safety of a Novel Ketogenic Ester, Bis-Hexanoyl (R)-1,3-Butanediol: A Randomized Controlled Trial in Healthy Adults
PubMed ID: 34208742
BH‑BD produced nutritional ketosis within 1 hour in healthy adults—evidence of rapid ketone availability (faster alternative fuel).
Fat burn (3)
- A Randomized Open-Label, Observational Study of the Novel Ketone Ester, Bis Octanoyl (R)-1,3-Butanediol, and Its Acute Effect on Ăź-Hydroxybutyrate and Glucose Concentrations in Healthy Older Adults
PubMed ID: 39985761
Dose‑dependent ketosis up to ~2.3 mM in older adults with beverage formulation—supports practical ketosis induction in older populations.
- Comparison of Ketogenic Diets with and without Ketone Salts versus a Low-Fat Diet: Liver Fat Responses in Overweight Adults
PubMed ID: 33802651
KS added to KD produced higher fasting BHB early — shows KS can help raise ketones quickly on KD.
- Tolerability and Safety of a Novel Ketogenic Ester, Bis-Hexanoyl (R)-1,3-Butanediol: A Randomized Controlled Trial in Healthy Adults
PubMed ID: 34208742
Randomized trial showed BH‑BD reliably produced nutritional ketosis (≥0.5 mM) within 1 hour and was generally safe—strong direct evidence.
Weight management (1)
- Effect of Exogenous Ketones as an Adjunct to Low-Calorie Diet on Metabolic Markers
PubMed ID: 41305632
BHB salt added to an 8‑week low‑calorie diet produced greater within‑group fat loss and preserved lean mass — direct clinical evidence supporting weight‑loss adjunct.
Illness recovery (1)
- Acute ingestion of a ketone monoester, whey protein, or their co-ingestion in the overnight postabsorptive state elicit a similar stimulation of myofibrillar protein synthesis rates in young males: a double-blind randomized trial
PubMed ID: 38215886
Ketone monoester increased myofibrillar protein synthesis to a magnitude similar to a small protein dose, supporting muscle repair/recovery.
Mental clarity (1)
- Defining metabolic migraine with a distinct subgroup of patients with suboptimal inflammatory and metabolic markers
PubMed ID: 36882474
Responder subgroup experienced clinical improvement in migraine and CRP reductions, consistent with clearer cognition in that subgroup.
