What is Taurine and Why Is it In Locked Down?

Do you want to build muscle and lose fat?

Do you wish you could just chill out and not be so stressed?

What about your sleep habits? Could they stand to be better?

You may be lacking in the amino acid taurine.

What is Taurine?

Taurine is a conditionally essential amino acid primarily found in the brain, heart, and skeletal muscle tissues of the body. It’s termed “conditionally” essential because under normal circumstances the human body has sufficient amounts of it to perform all its necessary functions.

However, in times of stress or intense physical exercise, the body may not be able to synthesize enough to meet demand...thereby shifting it from “conditionally” essential to essential.

Supplementing with taurine may help increase quantities in the body, thereby supporting athletic performance as well as many other aspects of human physiology.

Benefits of Taurine

Better Blood Flow and Vasodilation

A double blind study involving men aged 18-29 years old found that supplementing with a 1.5g dose of taurine increased vasodilation (widened blood vessels) in the test group.[1]

Greater vasodilation supports better blood flow and blood pressure regulation.

In terms of workout performance, increased blood flow provides better nutrient delivery to working muscles (oxygen, amino acids, carbohydrates, etc.) as well as some serious pumps during your workout!

Furthermore, greater blood flow may help boost muscle protein synthesis due to the increased flow of amino acids into the muscle tissue. And, remember, more muscle protein synthesis equals MORE GAINS![2]

Supports Healthy Glucose Levels

Taurine also has been found to enhance glucose uptake in a number of ways.

First, taurine stimulates the hypothalamus gland which enhances the effects of insulin, thereby reducing the feelings of hunger.[3]

Additionally, taurine may help reduce inflammation in the hypothalamus. This is noteworthy because an inflamed hypothalamus results in more insulin production, and with it, the possibility of obesity and chronically elevated insulin levels.[4]

With an inflamed hypothalamus more pancreatic insulin production may occur, and along with it the potential for obesity and notably higher insulin levels.

Supports Cognitive Function

One of the places in the body with the highest reserves of taurine is the brain.

As such, it should come as no surprise that taurine supplementation supports cognitive function and brain health.

For instance, taurine has been found to offer neuroprotective benefits, and thus help resist the effects of cognitive decline that come with aging, which will help individuals stay sharp as the years tick on by.[5]

Furthermore, taurine supplementation has been noted in animal studies to enhance memory and learning.[6]

To top it off, taurine may be helpful the morning after a terrible night’s sleep as research published in the British Journal of Surgery found that taurine could improve reaction time and offset the effects of a sleep-deprived state.

Aids Performance and Recovery

The main reason many of you reading this are how supplements (namely, taurine) can improve your performance, pumps, recovery, and overall results from a life committed to the iron.

Well, you’re in luck!

Taurine helps out here, too!

A study in the International Journal of Sports Nutrition and Exercise Metabolism found that taurine supplementation (1.66 grams) improved fat oxidation during exercise.[7]

Furthermore, a recent meta-analysis on taurine supplementation on aerobic and strength exercise noted that the versatile amino acid may help reduce markers that indicate muscular damage.[8]

Lower levels of these biomarkers correspond to faster recovery and reducing the onset of fatigue!

Lastly, taurine protects muscles from oxidative stress and attenuates arterial stiffness after eccentric exercise as well as plays a role in nitric oxide production, which helps blood flow, performance, and pumps!

Combat Stress and Improves Sleep

Taurine facilitates the production of the primary calming neurotransmitter -- GABA.[9] This helps calm the central nervous system (CNS) supporting lower levels of stress and anxiety.

Another benefit of increased GABA synthesis is its ability to help calm you and foster a good night’s sleep. Better quality sleep will facilitate better recovery and more muscle-building as well!

Enhanced Fat Loss

Finally, taurine may support fat loss. A double blind study using eleven trained cyclists found that administration of 1.66g of taurine/day increased fat oxidation by 17%![7] This resulted in an extra 20 calories being burned during exercise.

While this may not seem like a lot of calories burned, every little bit helps in the war against the “pudge.” So we’ll take any extra credit we can get when trying to get lean and mean.


Taurine provides many benefits for any athlete, bodybuilder, or gym rat looking to boost their performance and support long-term cardiometabolic health.

Through its various actions, it may help boost endurance, pumps, hydration, muscle protein synthesis and recovery. Outside of the workout window, it supports cardiovascular health, blood glucose, sleep and stress management.

No matter what your goal be it muscle gain, fat loss, or general health, taurine deserves a spot in your daily supplement rotation.

Condemned Labz LOCKED DOWN supplies a full 1,000mg of Taurine in every serving alongside 5 grams of creatine monohydrate and 3 grams of HydroMax.

Locked Down is a complete hydration support and cell volumization formula designed to aid performance, recovery, and muscle growth. Take one serving pre workout on training days and one serving any time of day on non-training days to keep your muscles hydrated and pumped!
