Creatine powers T cells' fight against cancer - Science Daily, 10/18/19 -
"Creatine, the organic acid that is popularly taken as a
supplement by athletes and bodybuilders, serves as a molecular battery for
immune cells by storing and distributing energy to power their fight against
cancer ... Taken together, these findings suggest that killer T cells really
need creatine to fight cancer ... Without it, they simply can't do their jobs
effectively ... These new findings add killer T cells to the list of
creatine-dependent cells, all of which utilize two distinct sources of power,
much like hybrid cars. The first power source is a metabolic process that is
similar to a fuel engine, converting nutrients like glucose, amino acids and
lipids into ATP, the energy currency of cells. The secondary power source is
creatine, which -- like a hybrid car's battery -- absorbs excess energy (in this
case, ATP) and stores it to be released when fuel is in short supply to keep the
cells working until more fuel can be burned" - See

Dietary
supplement boosts cognitive function in vegetarians - Science Daily, 4/8/19
- "Vegetarians who take the dietary supplement creatine
may enjoy improved brain function ... Creatine is a chemical stored in the
muscles and brain that helps build lean muscle ... One group took a daily
creatine supplement for four weeks, and the other group did not. Before and
after the trial, all participants took the ImPACT test, a widely used
standardized measure of neurocognitive function. The vegetarian supplement group
scored higher on the ImPACT test than the group that ate 10 or more servings of
meat, poultry or seafood per week. "Meat eaters did not show any significant
improvement of cognition following supplementation because [their] creatine
levels were already elevated [from their diet],"" - See

Creatine Increased Muscle
Mass, Not Strength, in Patients With RA - Medscape, 6/8/16 -
"Despite the increase in muscle mass, creatine
supplementation did not differ from placebo in effect on isometric knee extensor
strength, handgrip strength, or objectively assessed physical function" -
Note: If they ever do a study on it I'm betting they find the same problem

High-Dose Creatine
Promising in Prodromal Huntington's - Medscape, 3/14/14 -
"Creatine helps maintain intracellular energy levels and
so may prevent or impede the neurodegenerative process. Past studies have
reported that reduced energy stores play a role in neuronal loss ... The drug or
placebo came in packets, each with of 5 g of powder that could be added to foods
such as yogurt or apple juice. Participants could take the maximum tolerated
dose of the drug (30 g) daily. The creatine was pharmaceutical grade ...
Interestingly, more carriers (9 of 10) dropped out of the study during the
placebo-controlled phase, 7 of whom knew their genetic status (2 had been
assigned to placebo) ... That so many carriers dropped out of the study was
"completely counterintuitive," said Dr. Rosas. "You come in with this notion
that if you know what your risk ... the rate of cortical thinning in several
regions, including portions of precentral, superior and middle-temporal,
superior and middle frontal precuneus, posterior parietal and occipital was
significantly slower in the carriers taking creatine compared with the carriers
receiving placebo"

Huntington disease prevention trial shows creatine safe, slows progression -
Science Daily, 2/8/14 - "Among the ways that the mutated
form of the huntingtin protein damages brain cells is by interfering with
cellular energy production, leading to a depletion of ATP, the molecule that
powers most biological processes. Known to help restore ATP and maintain
cellular energy, creatine is being investigated to treat a number of
neurological conditions -- including Parkinson disease, amyotrophic lateral
sclerosis and spinal cord injury. Studies in mouse models of HD showed that
creatine raises brain ATP levels and protects against neurodegeneration ... In
participants who carried the HD mutation, the MRI scans taken at the outset of
the trial had revealed significant atrophy in regions of the cerebral cortex and
basal ganglia known to be affected by the disease. Followup MRI scans at six
months showed a slower rate of atrophy in participants taking creatine compared
to those on placebo. At the end of the second phase, the rate of brain atrophy
had also slowed in presymptomatic participants that started taking creatine
after 6 months on placebo"

Outmuscling major depression with creatine - Science Daily, 8/7/12 -
"women with major depressive disorder (MDD) who
augmented their daily antidepressant with 5 grams of creatine responded twice as
fast and experienced remission of the illness at twice the rate of women who
took the antidepressant alone ... Creatine is an amino acid made in the human
liver, kidneys, and pancreas. It also is found in meat and fish. Inside the body
it is converted into phosphocreatine and stored in muscle. During high-intensity
exercise, phosphocreatine is converted into ATP, an important energy source for
cells. For this reason, creatine has become a popular supplement among
bodybuilders and athletes who are trying to add muscle mass or improve athletic
ability ... The group that received creatine showed significantly higher
improvement rates on the HDRS at two and four weeks (32 percent and 68 percent)
compared to the placebo group (3.7 percent and 29 percent). At the end of eight
weeks, half of those in the creatine group showed no signs of depression
compared with one-quarter in the placebo group. There were no significant
adverse side effects associated with creatine"

Creatine in Type 2 Diabetes - Medscape, 5/10/11 -
"The patients were allocated to receive either creatine (CR) (5 g.d−1) or
placebo (PL) ...This is the first randomized controlled trial to describe the
beneficial effects of creatine supplementation on glycemic control in type 2
diabetic patients who underwent exercise training. As such, this supplement
emerges as a valuable nonpharmacological approach for treating diabetes ... the
mean reduction in HbA1c (−1.1%) was superior to that commonly seen with exercise
training[25] or metformin[10] treatment alone, pointing out the therapeutic
potential of this novel nutritional intervention"

nonusers were more likely to report feeling they were falling behind in
their training ... All creatine is doing is letting you do a few extra reps
in weight training, or cut a tenth of a second off your time ... You are
looking at a 5 to 10 percent performance improvement ... Athletes on
creatine might overtrain and might hurt themselves, but this would be the
result of the athletes expecting to do more than they can ... If you want to
go from training four days to training seven days, that could lead to
overtraining, but that's not creatine's fault"

Creatine supplementation and
endurance performance: surges and sprints to win the race - J Int Soc Sports
Nutr 2023 Dec;20 - "Mechanistically, creatine
supplementation elevates skeletal muscle phosphocreatine (PCr) stores
facilitating a greater capacity to rapidly resynthesize ATP and buffer hydrogen
ion accumulation. When co-ingested with carbohydrates, creatine enhances
glycogen resynthesis and content, an important fuel to support high-intensity
aerobic exercise. In addition, creatine lowers inflammation and oxidative stress
and has the potential to increase mitochondrial biogenesis. In contrast,
creatine supplementation increases body mass, which may offset the potential
positive effects, particularly in weight-bearing activities. Overall, creatine
supplementation increases time to exhaustion during high-intensity endurance
activities, likely due to increasing anaerobic work capacity. In terms of time
trial performances, results are mixed; however, creatine supplementation appears
to be more effective at improving performances that require multiple surges in
intensity and/or during end spurts, which are often key race-defining moments.
Given creatines ability to enhance anaerobic work capacity and performance
through repeated surges in intensity, creatine supplementation may be beneficial
for sports, such as cross-country skiing, mountain biking, cycling, triathlon,
and for short-duration events where end-spurts are critical for performance,
such as rowing, kayaking, and track cycling" - See

Effects of creatine
supplementation on memory in healthy individuals: a systematic review and
meta-analysis of randomized controlled trials - Nutr Rev 2022 Aug 19 -
"From an energy perspective, the brain is very
metabolically demanding. It is well documented that creatine plays a key role in
brain bioenergetics. There is some evidence that creatine supplementation can
augment brain creatine stores, which could increase memory ... Overall, creatine
supplementation improved measures of memory compared with placebo (standard mean
difference [SMD] = 0.29, 95%CI, 0.04-0.53; I2 = 66%; P = 0.02). Subgroup
analyses revealed a significant improvement in memory in older adults (66-76
years) (SMD = 0.88; 95%CI, 0.22-1.55; I2 = 83%; P = 0.009) compared with their
younger counterparts (11-31 years)"

Creatine in Health and
Disease - Nutrients 2021 Jan 29 - "Although creatine
has been mostly studied as an ergogenic aid for exercise, training, and sport,
several health and potential therapeutic benefits have been reported. This is
because creatine plays a critical role in cellular metabolism, particularly
during metabolically stressed states, and limitations in the ability to
transport and/or store creatine can impair metabolism. Moreover, increasing
availability of creatine in tissue may enhance cellular metabolism and thereby
lessen the severity of injury and/or disease conditions, particularly when
oxygen availability is compromised. This systematic review assesses the
peer-reviewed scientific and medical evidence related to creatine's role in
promoting general health as we age and how creatine supplementation has been
used as a nutritional strategy to help individuals recover from injury and/or
manage chronic disease. Additionally, it provides reasonable conclusions about
the role of creatine on health and disease based on current scientific evidence.
Based on this analysis, it can be concluded that creatine supplementation has
several health and therapeutic benefits throughout the lifespan" - See

Creatine Supplementation and
Brain Health - Nutrients 2021 Feb 10 - "There is a
robust and compelling body of evidence supporting the ergogenic and therapeutic
role of creatine supplementation in muscle. Beyond these well-described effects
and mechanisms, there is literature to suggest that creatine may also be
beneficial to brain health (e.g., cognitive processing, brain function, and
recovery from trauma). This is a growing field of research, and the purpose of
this short review is to provide an update on the effects of creatine
supplementation on brain health in humans. There is a potential for creatine
supplementation to improve cognitive processing, especially in conditions
characterized by brain creatine deficits, which could be induced by acute
stressors (e.g., exercise, sleep deprivation) or chronic, pathologic conditions
(e.g., creatine synthesis enzyme deficiencies, mild traumatic brain injury,
aging, Alzheimer's disease, depression). Despite this, the optimal creatine
protocol able to increase brain creatine levels is still to be determined.
Similarly, supplementation studies concomitantly assessing brain creatine and
cognitive function are needed"

A Five-Ingredient Nutritional
Supplement and Home-Based Resistance Exercise Improve Lean Mass and Strength in
Free-Living Elderly - Nutrients 2020 Aug 10 - "Old
age is associated with lower physical activity levels, suboptimal protein
intake, and desensitization to anabolic stimuli, predisposing for age-related
muscle loss (sarcopenia). Although resistance exercise (RE) and protein
supplementation partially protect against sarcopenia under controlled
conditions, the efficacy of home-based, unsupervised RE (HBRE) and
multi-ingredient supplementation (MIS) is largely unknown ... Thirty-two
sedentary men underwent twelve weeks of home-based resistance band training (3
d/week), in combination with daily intake of a novel five-nutrient supplement
('Muscle5'; M5, n = 16, 77.4 ± 2.8 y) containing whey, micellar casein,
creatine, vitamin D, and omega-3 fatty acids, or an isocaloric/isonitrogenous
placebo (PLA; n = 16, 74.4 ± 1.3 y), containing collagen and sunflower oil.
Appendicular and total lean mass (ASM; +3%, TLM; +2%), lean mass to fat ratios
(ASM/% body fat; +6%, TLM/% body fat; +5%), maximal strength (grip; +8%, leg
press; +17%), and function (5-Times Sit-to-Stand time; -9%) were significantly
improved in the M5 group following HBRE/MIS therapy (pre vs. post tests; p <
0.05). Fast-twitch muscle fiber cross-sectional areas of the quadriceps muscle
were also significantly increased in the M5 group post intervention (Type IIa;
+30.9%, Type IIx, +28.5%, p < 0.05). Sub-group analysis indicated even greater
gains in total lean mass in sarcopenic individuals following HBRE/MIS therapy
(TLM; +1.65 kg/+3.4%, p < 0.05). We conclude that the Muscle5 supplement is a
safe, well-tolerated, and effective complement to low-intensity, home-based
resistance exercise and improves lean mass, strength, and overall muscle quality
in old age" - [Nutra
