What Are Exogenous Ketones?

Exogenous ketones are nearly identical to the ketones your body makes on the keto diet. These ketones fuel your body with alternate energy when carbs are scarce. Your main energy ketone—beta-hydroxybutyrate (BHB)—is the active ingredient in Key Keto.

Clean Keto? We Got You Covered.

  • No added sugar
  • No artificial colors, sweeteners, or flavorings
  • No gluten, soy, or dairy
  • No harmful chemicals

Safety information

Do not exceed recommended dose. Consult a physician before use if pregnant, nursing, under the age of 18, or if you have a serious medical condition. Anecdotal responses of dizziness, headaches, and stomach discomfort after consumption have been reported.

Exogenous ketones are generally not tasty and not meant to taste like a sugary fruit smoothie. Key Nutrients has spent countless hours ensuring the best tasting product possible. That said, some will still find it to be bitter or have less than pleasant aftertaste. For first timers, we recommend you start with ½ scoop.

Anytime Energy

Slow morning? Afternoon slump? Exogenous ketone supplements are instant fuel for brain and body, so you can stay productive, crush your workout, and win the day.

A Taste You’ll Look Forward To.

Most ketone supplements taste bitter and dissolve poorly. Key Keto is a scrumptious stevia-sweetened mix that dissolves like a dream.

Adapt To Keto

Fat-adapting doesn’t happen overnight. Boosting ketones helps bridge the gap and relieve keto flu symptoms as you transition to a low-carb diet.

BHB Salts

Each serving comes with 11.1 grams of high-quality patented BHB and each jar contains 278 grams of product, which gives you 15 full servings or 30 half scoop-servings.

Key Keto

The perfect and delicious way to boost my ketones.

Key Keto

They give me a great boost of clean energy with zero caffeine, so I don’t worry about it keeping me awake if I workout in the evening.

It’s so hard to find good, clean exogenous ketones for an affordable price but thank you key nutrients! This flavor is delicious and keeps me energized all day!

Will Key Keto put me in ketosis?

Yes, taking exogenous ketones elevates blood ketone levels for several hours.

When should I take Key Keto?

In the morning to increase alertness, in the afternoon to stay peppy, before a workout to increase energy, or as needed to support your transition to the keto diet.

Do I need to be on a low-carb diet to take Key Keto?

No, exogenous ketones will elevate ketones even in the presence of carbs. Still, we recommend a keto diet for maximum synergy and benefits.

Does Key Keto increase fat-burning and stimulate weight loss?

Not directly. Any product claiming these benefits should be viewed with suspicion. Rather, Key Keto gives you energy and eases keto-adaptation, both of which can help support your long-term weight loss goals.

I knew when I got Keto Breathe it was Working

Great taste, I was actually surprised even though I read the reviews and other people said so. I also have to say I do think it has kicked me into ketosis a lot faster than I would normally be, my mother complained about my Keto breathe the other day and I knew it was working sad to say. LOL
