How Stamina 13 builds cardio foundations

Helping runners address nutritional gaps, 1 scoop at a time.

Runners often plan their diets well for carb counting, but neglect to consider the rest of our body's unique needs for cardio exercise (we've made the same mistake). Stamina 13 specifically addresses that gap with scientifically formulated amino acids, adaptogens and ingredients.

How do I know if Stamina 13 is right for me?

Stamina 13 is great for anyone with an active lifestyle who wants to maintain a healthy cardio system. It provides the support you need to operate at your maximum potential, whether you're going for a quick ride or heading into race day.

Stamina 13 is suitable for adults of all ages and lifestyles, including recreational fitness enthusiasts and professional athletes.

Children, pregnant or nursing women should seek professional medical advice before taking this or any other dietary supplement. If you are on blood pressure medication, have hypotension, or have a history of kidney stones, consult your doctor before taking Stamina 13.

How long will it take to see results?

Bioavailability begins in as little as 2-3 hours. However, studies show that the ideal loading phase for Stamina 13's active ingredients is between 3 to 4 weeks of daily intake to build a baseline of nutrients in your body.

As we're all different, many factors can influence how quickly you notice an impact. This includes factors like the consistency of your routine, your health, diet, lifestyle and training regimen.

How do I take Stamina 13?

Take 1 scoop daily with water or in a smoothie/juice.

We recommend taking Stamina 13 ~2-3 hours before your regular training time (even if you are not training that day), to allow time for bioavailability.

If you are competing or training at a different time one day, we recommend shifting your dose that day to remain 2-3 hours prior to your event.

Will this help me run faster?

Stamina 13 is not a replacement for hard training and effort :)

That being said, Stamina 13 is formulated to help maximize exercise efforts and achieve faster times via stamina support such as delaying the onset of lactic acid buildup, improving VO2 efficiency, and increasing blood flow.

How does Stamina 13 taste?

Stamina 13 uses only real, natural ingredients, and has a balanced taste between that of a cold pressed beet juice with the zip of lemon and ginger.

Should I still carb load/cycle?

Yes! Stamina 13 is designed to be a foundational pillar of active lifestyles. We recommend continuing to manage your glycogen stores.
