Creatine 101 — What Is It and What Does It Do?

creatine is the number-one supplement for improving performance in the gymnasium. Studies show that it can increase muscle mass, forte and practice performance ( 1, 2 ). additionally, it provides a number of other health benefits, such as protecting against neurological disease ( 3, 4, 5, 6 ).

Some people believe that creatine is dangerous and has many side effects, but these are not supported by tell ( 7, 8 ). In fact, it is one of the populace ’ s most test supplements and has an outstanding guard profile ( 1 ). This article explains everything you need to know about creatine . partake on Pinterest

What is creatine?

Creatine is a means that is found naturally in muscle cells. It helps your muscles produce energy during clayey lift or high-intensity use. Taking creatine as a append is very popular among athletes and bodybuilders in order to gain muscle, enhance strength and improve exercise operation ( 1 ). chemically speaking, it shares many similarities with amino acids. Your body can produce it from the amino acids glycine and arginine. several factors affect your consistency ’ sulfur creatine stores, including meat consumption, exercise, sum of muscle mass and levels of hormones like testosterone and IGF-1 ( 9 ). about 95 % of your body ’ second creatine is stored in muscles in the form of phosphocreatine. The other 5 % is found in your brain, kidneys and liver ( 9 ). When you supplement, you increase your stores of phosphocreatine. This is a shape of store energy in the cells, as it helps your body produce more of a high-energy atom called ATP. ATP is frequently called the torso ’ s energy currency. When you have more ATP, your body can perform better during exercise ( 9 ). Creatine besides alters several cellular processes that lead to increased muscle multitude, force and recovery ( 1, 2 ) .

Summary Creatine is a substance found naturally in your body — particularly in brawn cells. It is normally taken as a supplement .

How does it work?

creatine can improve health and acrobatic performance in several ways. In high-intensity exercise, its primary function is to increase the phosphocreatine stores in your muscles. The extra stores can then be used to produce more ATP, which is the key energy reference for heavy lift and high-intensity practice ( 10, 11 ). Creatine besides helps you gain muscle in the following ways :

  • Boosted workload: Enables more total work or volume in a single training session, which is a key factor in long-term muscle growth (12).
  • Improved cell signaling: Can increase satellite cell signaling, which aids muscle repair and new muscle growth (13).
  • Raised anabolic hormones: Studies note a rise in hormones, such as IGF-1, after taking creatine (14, 15, 16).
  • Increased cell hydration: Lifts water content within your muscle cells, which causes a cell volumization effect that may play a role in muscle growth (17, 18).
  • Reduced protein breakdown: May increase total muscle mass by reducing muscle breakdown (19).
  • Lower myostatin levels: Elevated levels of the protein myostatin can slow or totally inhibit new muscle growth. Supplementing with creatine can reduce these levels, increasing growth potential (20).

creatine supplements besides increase phosphocreatine stores in your brain, which may improve brain health and prevent neurological disease ( 3, 21, 22, 23, 24 ) .

Summary Creatine gives your muscles more department of energy and leads to changes in cell routine that increase muscle growth .

Effects on muscle gain

Creatine is effective for both short- and long-run muscle growth ( 25 ). It assists many different people, including sedentary individuals, older adults and elite athletes ( 17, 25, 26, 27 ). One 14-week study in older adults determined that adding creatine to a weight-training program importantly increased leg force and muscleman mass ( 27 ). In a 12-week discipline in weightlifters, creatine increased muscle fiber growth 2–3 times more than training alone. The increase in total body mass besides doubled aboard one-rep soap for terrace bid, a common lastingness exercise ( 28 ). A big review of the most popular supplements selected creatine as the single most beneficial supplement for adding muscleman mass ( 1, 25 ) .

Summary Supplementing with creatine can result in significant increases in muscle mass. This applies to both untrained individuals and elite athletes .

Effects on strength and exercise performance

creatine can besides improve persuasiveness, exponent and high-intensity exercise performance. In one review, adding creatine to a trail program increased strength by 8 %, weightlifting performance by 14 % and bench weigh one-rep soap by up to 43 %, compared to training alone ( 29 ). In well-trained persuasiveness athletes, 28 days of supplementing increase bike-sprinting operation by 15 % and bench-press performance by 6 % ( 30 ). Creatine besides helps maintain lastingness and train performance while increasing muscle mass during intense over-training ( 31 ). These noticeable improvements are chiefly caused by your body ’ south increased capacity to produce ATP.

normally, ATP becomes depleted after 8–10 seconds of high-intensity natural process. But because creatine supplements help you produce more ATP, you can maintain optimum performance for a few seconds longer ( 10, 11, 32, 33 ) .

Summary Creatine is one of the best supplements for improving intensity and high-intensity use performance. It works by increasing your capacitance to produce ATP energy .

Impact on your brain

barely like your muscles, your genius stores phosphocreatine and requires plenty of ATP for optimum function ( 21, 22 ). Supplementing may improve the play along conditions ( 3, 24, 34, 35, 36, 37, 38, 39 ) :

  • Alzheimer’s disease
  • Parkinson’s disease
  • Huntington’s disease
  • Ischemic stroke
  • Epilepsy
  • Brain or spinal cord injuries
  • Motor neuron disease
  • Memory and brain function in older adults

Despite the likely benefits of creatine for treating neurological disease, most current research has been performed in animals. however, one six-month analyze in children with traumatic brain injury observed a 70 % reduction in fatigue duty and a 50 % reduction in dizziness ( 40 ). Human inquiry suggests that creatine can besides aid older adults, vegetarians and those at risk of neurological diseases ( 39, 41 ). Vegetarians tend to have depleted creatine stores because they don ’ deoxythymidine monophosphate eat kernel, which is the main natural dietary source. In one study in vegetarians, supplementing caused a 50 % improvement in a memory trial and a 20 % improvement in news test scores ( 21 ). Although it can benefit older adults and those with reduce stores, creatine exhibits no consequence on brain function in healthy adults ( 42 ) .

Summary creatine may reduce symptoms and slow the progress of some neurological diseases, although more inquiry in humans is needed .

Different Types of Supplements

The most coarse and well-researched supplement mannequin is called creatine monohydrate. many other forms are available, some of which are promoted as superior, though evidence to this effect is lacking ( 1, 7, 49 ). Creatine monohydrate is identical bum and is supported by hundreds of studies. Until new inquiry claims otherwise, it seems to be the best option .

Summary The best form of creatine you can take is called creatine monohydrate, which has been used and studied for decades .

Dosage instructions

many people who supplement start with a cargo phase, which leads to a rapid increase in muscleman stores of creatine. To load with creatine, take 20 grams per day for 5–7 days. This should be split into four 5-gram servings throughout the sidereal day ( 1 ). assimilation may be slenderly improved with a carb- or protein-based meal ascribable to the associate release of insulin ( 50 ). Following the load period, take 3–5 grams per day to maintain high levels within your muscles. As there is no profit to cycling creatine, you can stick with this dose for a long time. If you choose not to do the load phase, you can simply consume 3–5 grams per sidereal day. however, it may take 3–4 weeks to maximize your stores ( 1 ). Since creatine pulls water into your brawn cells, it is advisable to take it with a glass of body of water and stay well hydrated throughout the day .

Summary To load with creatine, take 5 grams four times per sidereal day for 5–7 days. then take 3–5 grams per day to maintain levels .

Safety and side effects

Creatine is one of the most well-researched supplements available, and studies lasting up to four years reveal no negative effects ( 8, 51 ). One of the most comprehensive examination studies measured 52 blood markers and observed no adverse effects following 21 months of supplementing ( 8 ). There is besides no evidence that creatine harms the liver-colored and kidneys in healthy people who take normal doses. That said, those with preexisting liver or kidney problems should consult with a sophisticate before supplementing ( 8, 51, 52 ). Although people consociate creatine with dehydration and cramps, research doesn ’ t support this radio link. In fact, studies suggest it can reduce cramps and dehydration during endurance exercise in high hotness ( 53, 54 ). One 2009 sketch found that creatine supplementation is associated with an increase in a hormone called DHT, which can contribute to hair loss. More inquiry is needed, but people who are predisposed to hair passing may wish to avoid this addendum ( 55 ) .

Summary Creatine exhibits no harmful side effects. Though it ’ sulfur normally believed to cause dehydration and cramps, studies don ’ thymine support this .

The bottom line

At the end of the day, creatine is one of the cheapest, most effective and safest supplements you can take. It supports quality of life in older adults, brain health and use performance. Vegetarians — who may not obtain adequate creatine from their diet — and older adults may find supplementing particularly utilitarian. Creatine monohydrate is likely the best kind.
