BMI Calculator

Body mass index (BMI) is a measure of your body weight per unit of height (calculated by dividing your weight in kilograms by your height in meters squared). BMI is often used by doctors, personal trainers, and other healthcare professionals to determine if someone is over, under, or average weight. Although not as accurate or useful to know as your body fat percentage, body mass index gives you a general idea of whether or not you should lose weight.

Frequently Asked Questions

Are BMI charts accurate?

Sort of.

BMI charts often underestimate how much fat people are carrying if they don’t have much muscle mass (they don’t lift weights), and this is particularly true among people with lots of excess body fat.

That said, BMI charts are usually accurate in determining if someone is obese or not (that is, if a BMI chart says someone is obese, there’s a 95% chance that they are actually obese).

Are BMI charts accurate for women?

Yes.

Although women carry more essential body fat than men, it’s not a big enough difference to affect your BMI.

Are BMI charts accurate for “big-boned” people?

Yes.

Although some people do have thicker, denser bones than others (thanks to resistance training and genetics), the differences are too small to meaningfully impact your BMI.

Are BMI charts accurate for muscular people?

Sort of.

BMI charts will often classify muscular, lean people as “overweight,” because BMI charts only account for total body weight and not body composition. Thus, if you know you’re fairly lean (less than 15% body fat for men and 25% for women), don’t worry if you’re “overweight” according to a BMI chart—research shows this isn’t unhealthy.

That said, if a BMI chart classifies someone as “obese,” there’s virutally no chance this is due to naturally high levels of muscle mass. Either the person is carrying more body fat than they realize or they’re taking steroids.

So, if you live in the United States, your order ships free regardless of order size, and if you live anywhere else, your order ships free when it’s over $199.

Why the restriction on international orders? Unfortunately, shipping abroad is very expensive, and if we didn’t require a minimum order size, we’d lose a lot of money.

Clinically Effective Doses

Great ingredients aren't enough to make a great product—you also need correct doses.

That’s why we use the exact doses of every ingredient that have safely produced the desired benefits in peer-reviewed studies.

Made in USA

Where your supplements are made matters, because rules and regulations regarding quality and purity differ from country to country.

And if you want to ensure the supplements you’re swallowing every day are safe and effective, you want products produced in the USA.

That’s why all of our supplements are made in America in NSF-certified and FDA-inspected facilities that operate in accordance with the Current Good Manufacturing Practice (cGMP) regulations.

We pay a premium to work with the best manufacturers in the country, but it’s the only way we can also produce the best all-natural sports supplements.

Lab Tested

Did you know that studies have shown that many supplements contain dangerously high levels of toxins like lead, arsenic, and cadmium?

Not ours.

Every ingredient of every supplement we produce is tested for heavy metals, microbes, allergens, and other contaminants to ensure they meet the strict purity standards set by the FDA.

Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health and that more research is needed.

That’s why all of our supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

Science-Backed Ingredients & Doses

Unlike some supplement companies, we don’t sell dubious white labeled or off-the-shelf formulations.

Instead, our custom and unique formulations are the result of extensive reviews of the scientific literature to discover the most effective ingredients for each.
