Bottle, label, capsule, and packaging appearance may vary slightly from images shown.

Whether you're starting low-carb again, training for a fasted morning, or just trying to push the eating window from 12pm to 2pm — there is a window where your body is between two fuel systems and you feel like garbage. Two capsules a day during the transition. Not a weight-loss pill — those don't exist. The bridge across the worst few days.

Smoothed the keto-flu transition. Energy held during fasting windows.

A quieter system

Three ways the shift shows up.

Softens the keto-flu week.

Onramp

Softens the keto-flu week.

Days three through five of cutting carbs are where every keto attempt dies. BHB takes the edge off that window so you make it to the other side.

For the 18-hour eating window.

Fast

For the 18-hour eating window.

If you're pushing your first meal to noon or 2pm, this is the morning support that keeps the energy from dropping out before lunch.

Less of the keto-brain haze.

Fog

Less of the keto-brain haze.

The mental fog of the first low-carb week is the single most-quoted reason people quit. Less of that — more head-down hours where you don't want to nap.

What's inside

The label is the whole story.

Every ingredient, the form we use, the dose per serving, the mechanism that makes it relevant, and the peer-reviewed study that backs it.

1 mg per serving

Magnesium (from magnesium BHB)

Form: 1 mg (4% DV) per 2-cap serving

Delivered through the magnesium-salt form of BHB — an exogenous-ketone source that also contributes a small amount of magnesium, a mineral often depleted during low-carb transitions.

1 mg per serving

Sodium (from sodium BHB)

Form: 1 mg (<1% DV) per 2-cap serving

Delivered through the sodium-salt form of BHB — an exogenous-ketone source that also contributes a trace of sodium, an electrolyte the body sheds quickly in the early keto phase.

Proprietary blend

Keto Proprietary Blend

Calcium Citrate, MCT Powder, Calcium BHB (β-Hydroxybutyric Acid), Magnesium BHB (β-Hydroxybutyric Acid), Sodium BHB (β-Hydroxybutyric Acid)

Form: 800 mg per 2-cap serving (Daily Value not established)

A blend of three BHB salts (calcium, magnesium, and sodium β-hydroxybutyrate) plus MCT powder and calcium citrate. BHB is the salt form of the primary ketone body the liver produces during ketogenic eating or fasting; MCT powder supplies medium-chain fats the liver readily converts toward ketones. Together they're studied as exogenous-ketone support for adults following ketogenic protocols.

Honest answers

Questions you actually asked

Will this make me lose weight?

Not on its own. Exogenous BHB does not produce weight loss in the absence of dietary ketosis or fasting. This supplement supports the protocol — it doesn't replace it. Weight-loss claims for BHB supplements are not FDA-substantiated.

Will this put me into ketosis?

It temporarily raises blood-ketone levels, but it doesn't put your body into the metabolic state of ketosis the way diet does. Think of it as supplemental fuel during the transition or fasting window.

How quickly will I notice anything?

Subjective ketone-support effects (mental clarity, energy) can occur within 30–60 minutes of dosing.

When should I take it?

With the first meal of a ketogenic day, or during an extended fasting window. Some users take it pre-workout during fasted training.

Will it break my fast?

BHB is technically caloric (~4 cal/g). Strict autophagy-focused fasters consider any caloric intake a break. Most intermittent-fasting practitioners view BHB as compatible with the fasting protocol.

Can I take it without doing keto?

You can, but the benefit profile assumes you're doing a ketogenic-style protocol or fasting. Without that, BHB salts are a relatively expensive electrolyte supplement.

Can I take it with my ashwagandha?

Yes — they don't conflict.

Will it interact with my medication?

BHB salts contribute meaningful sodium, calcium, and magnesium. If you take diuretics, blood-pressure medication, or have kidney conditions, talk to your physician before starting.

What if it doesn't work for me?

Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the bottles back.
