How Much BHB Per Day? The Metatrim BHB 800 mg Dose, Explained

How much BHB per day depends on the product, but most exogenous-ketone supplements supply between a few hundred milligrams and a couple of grams of beta-hydroxybutyrate per serving. Metatrim BHB delivers an 800 mg two-capsule serving of magnesium, calcium and sodium BHB — a moderate, once-daily dose meant to complement a keto diet, not replace it.

“How much BHB per day?” is a common question before buying an exogenous-ketone supplement, and a hard one to answer cleanly because there is no government-set daily value for beta-hydroxybutyrate. This guide breaks down the 800 mg two-capsule serving in Metatrim BHB, shows how it compares with typical exogenous-ketone doses, and teaches you to read a proprietary-blend label honestly rather than by the biggest number on the front.

How much BHB per day should you take?

There is no single official daily dose for exogenous BHB, but most capsule products supply between roughly 300 mg and 2,000 mg of beta-hydroxybutyrate per serving, taken once or twice a day with water. Because BHB is a nutrient your body already makes and burns, regulators have not set a recommended daily amount as they have for vitamins. That leaves the “right” dose defined mostly by the product in your hand and how your stomach tolerates it.

In practice, three things shape a sensible amount: the form (salts versus esters), the reason you take it (daily keto support versus a pre-workout push), and simple tolerance, since larger single doses of BHB salts can cause stomach upset. For everyday low-carb support, a moderate once-daily serving is the practical middle ground.

What is the 800 mg serving in Metatrim BHB?

The 800 mg serving in Metatrim BHB is a proprietary blend of three mineral BHB salts — magnesium, calcium and sodium beta-hydroxybutyrate — delivered in two capsules, with 30 servings per bottle. That figure is the combined weight of the blend, and understanding what it does and does not include is the key to reading the product honestly.

How many capsules make a serving?

A serving of Metatrim BHB is two capsules. The 800 mg applies to those two capsules together, not to each one, so a single capsule carries roughly 400 mg of the blend. This matters when you compare labels: a product boasting “800 mg” per capsule across a three-capsule serving is quoting a very different total from one quoting 800 mg per serving.

How many servings are in a bottle?

Each bottle holds 60 capsules, which is 30 two-capsule servings — a one-month supply at the labeled dose. That math is worth doing before you judge price: cost per serving, not cost per bottle, is the fair comparison across brands and pack sizes.

What else is in the capsule?

Beyond the BHB blend, Metatrim BHB keeps the “other ingredients” line short — a gelatin capsule shell and a little rice flour. A short filler list is a good sign, because it means most of the capsule weight is the ingredient you are actually buying.

How does 800 mg compare to typical exogenous-ketone doses?

An 800 mg serving is a moderate capsule dose — well below the multi-gram amounts used in some ketone-ester research, but squarely in line with the everyday BHB-salt capsules most people take. The eye-catching blood-ketone spikes in studies usually come from ketone esters dosed in grams, a format that is expensive, strongly flavored and built for research and elite sport, not daily habit.

Capsule BHB salts trade that peak for convenience, tolerability and electrolyte value. The table below sets the common formats side by side.

Powder and capsule figures are not apples-to-apples: a multi-gram scoop is mostly a larger dose of the same mineral-bound BHB, and a bigger number is not automatically a better daily fit. For the underlying chemistry, see our explainer on what BHB is and how exogenous ketones work.

How do you read a proprietary-blend label honestly?

A proprietary blend lists the total combined weight of a group of ingredients without disclosing the exact milligrams of each one, so an “800 mg BHB blend” tells you the total but not the precise split between magnesium, calcium and sodium BHB. This is legal and common, but it means you have to read a little more carefully to compare products fairly.

Check the total, then the serving size

Start with the blend total, then immediately find the serving size next to it. An 800 mg blend in a two-capsule serving is a different thing from 800 mg in a three- or four-capsule serving. Normalizing to a per-serving basis — and ideally a per-capsule basis — is the only way to compare two labels honestly.

Look for named salts, not just “BHB”

A transparent label names its BHB salts. Seeing magnesium, calcium and sodium BHB spelled out, as on the Metatrim BHB panel, tells you the blend spreads across several electrolyte minerals rather than leaning on one. A label that only says “BHB” with no mineral partners named is giving you less to work with.

Do not equate a bigger number with a better product

Because BHB salts include the weight of their mineral partners, a large blend figure is partly mineral, not pure ketone — and higher single doses raise the odds of digestive upset. The most useful label is a clear one: a stated total, named salts, an honest serving size and a short other-ingredients line.

When is the best time to take your daily BHB?

Most people take their daily BHB capsules once in the morning or around exercise, with water, and consistency matters more than perfect timing. Because exogenous BHB raises blood ketones for only a few hours, the goal is to place that window where it is most useful to you.

In the early weeks of a low-carb diet, a morning dose can supply ketone fuel and electrolytes while your own ketone production catches up — the stretch many associate with the “keto flu.” If you train, taking it before a workout puts the ketone window around your session. Either way, take it with a full glass of water; if you are also managing electrolytes, see our guide to keto electrolytes.

Is a higher BHB dose always better?

No — a higher BHB dose raises blood ketones more, but it does not increase your own ketone production or put you into nutritional ketosis any faster. Exogenous BHB is a temporary top-up of fuel; the fat-adapted state that defines real ketosis comes only from restricting carbohydrates.

There are also practical reasons not to push the number. Larger single doses of BHB salts are the most likely to cause stomach upset, and because sodium BHB is one of the salts, a bigger dose adds more sodium to your day — worth noting if you have blood-pressure, kidney or heart concerns. A moderate, consistent serving like the 800 mg in Metatrim BHB is built around that trade-off: enough to supply ketone fuel and electrolytes, gentle enough to take daily. New to the diet?
