PerformanceWeak evidence
BHB ketones
Also known as: beta-hydroxybutyrate, exogenous ketones, keto booster
BHB (beta-hydroxybutyrate) is a ketone body the body makes naturally during fasting or a ketogenic diet, which the brain and muscles can use as fuel. Supplements temporarily raise blood ketones, but they do not burn fat on their own.
What it is used for
- temporary rise in blood ketones – strong evidence for this effect
- easing the transition to a keto diet – weak evidence
- performance and weight loss – weak evidence, inconsistent results
Forms and how they differ
BHB salts (sodium, magnesium, calcium, potassium)
weaker effect, high mineral load – especially sodium
ketone esters
stronger effect, bitter taste, pricier
D- vs. DL-BHB
the body mainly uses the D form; DL mixes are cheaper
Pairs well with
Water, a ketogenic or low-carb diet, sensible electrolytes.
Do not combine / separate
Watch total sodium with BHB salts; do not combine with other mineral supplements without checking doses.
Watch out for
Not suitable in pregnancy, breastfeeding, type 1 diabetes or with kidney, liver or heart disease. With high blood pressure or when taking medicines (especially for diabetes), consult your doctor.
Safety
May cause digestive upset; do not exceed the label dose.
Practical tip
BHB does not replace a ketogenic diet or a calorie deficit – it is only a short-term ketone source.

Strong evidenceModerate evidenceWeak evidenceNo evidence
Strong = several good human studies or official recommendations; moderate = promising but smaller studies; weak = few studies or mixed results; no evidence = claims not confirmed.
Combination check
