Using High Strength Magnesium to Naturally
Revitalise and Re-energise your Muscles and Improve Energy Levels -
by Rachel Ainscough BA (Hons)
It’s not just athletes who suffer from aching, tired muscles and symptoms
of fatigue. The stresses and strains of modern day living have made
these complaints all too common among many people every day. Conditions
ranging from PMS associated muscular cramps and sports related muscle
spasms, to more severe cases of fibromyalgia and chronic fatigue are
becoming increasingly common. Fortunately, there are simple nutritional
steps, incorporating high strength magnesium supplementation, which
can be taken to help improve these often debilitating symptoms.
The diverse role of magnesium
Research studies have recently shown that magnesium plays an even greater
role in health than was previously thought. Second only to potassium
in terms of concentration within the individual cells in the body, the
function of magnesium revolves primarily around its ability to activate
many enzymes. Magnesium participates in more than 300 enzymatic reactions
in the body and these include those responsible for energy metabolism,
fatty acid metabolism, protein synthesis (essential for rebuilding after
injury), neuromuscular contractions / relaxations, bone integrity and
prostaglandin synthesis to name but a few.
This often forgotten mineral therefore has a significant role to play
in the production of energy and in maintaining and optimising muscle
health.
Widespread deficiency
Unfortunately, poor soil and food processing now make it highly unlikely
that we are getting enough magnesium in our diet and consequently have
contributed to widespread deficiencies in this vital mineral, significantly
increasing the need for its supplementation.
Magnesium – for energy production and faster muscle recovery
Energy in the body is produced in the form of ATP, through the process
of cellular respiration. There are various stages involved in cellular
respiration and various micro-nutrient co-factors needed at each stage.
Magnesium is perhaps the most important, as it is actively involved
as a co-factor in every single step. It is often recommended therefore
that professional athletes or anyone who engages in heavy physical labour
should keep magnesium levels up, as this is what facilitates oxygen
and energy being delivered to working muscle tissue. It is also interesting
that the muscles themselves actually contain about 26% of all magnesium
found in the body, with 60% in the bone and the rest in soft tissue
and body fluids. The tissues with the highest concentration of magnesium
are those that are metabolically active, which again attests to magnesium’s
critical role in energy production.
Magnesium deficiency in chronic fatigue syndrome
Magnesium supplementation has also had some success in the alleviation
of symptoms of chronic fatigue. Research suggests that an underlying
magnesium deficiency, even if “subclinical”, can result in chronic fatigue
and symptoms similar to chronic fatigue syndrome (CFS). In a UK trial
assessing the effect of magnesium supplementation in CFS, significantly
more of the patients who had received magnesium reported improved energy
levels, better emotional state, and less pain than placebo (1).
Magnesium and fibromyalgia
Some researchers suggest that magnesium status should be checked in
all patients who present with chronic muscle pain (2). Insufficient
erythrocyte magnesium content has been identified in individuals with
CFS, myalgia and FMS compared with those of normal controls in several
studies (3). Magnesium abnormalities in patients with fibromyalgia have
also been associated with impairment of thiamin (B1) metabolism (4).
Since this vitamin is needed in the bioenergetics of the mitochondria,
reduced output of ATP can therefore occur as a result of altered magnesium
levels.
Gastro-intestinal tolerance
Oral magnesium supplementation has often been complicated by side effects
of poor gastrointestinal tolerance, including malabsorption and diahorreah.
Using a glycinate chelated form of magnesium overcomes these problems.
Even in individuals with known malabsorption and intestinal permeability
alteration, the absorption of magnesium diglycinate has been shown to
be substantially greater than inorganic magnesium salts (23.5% vs. 11.8%)
and is better tolerated (5).
Research indicates that high strength magnesium supplementation can
be more effective for muscle support and cellular energy production
when combined with a specific range of supporting nutrients.
Malic acid
Malic acid is synthesised as part of the Kreb’s cycle and studies indicate
the importance of its role in this energy producing cycle (6&7). Low
levels of malic acid have been shown in patients who have fibromyalgia
(8). Studies indicate that supplementation with malic acid, especially
in conjunction with magnesium, may relieve the symptoms of pain and
fatigue associated with fibromyalgia and CFS (9).
Taurine
Taurine is an amino acid-like compound found in abundance in most tissues.
In skeletal muscle its distribution depends on the type of fibres present,
with muscles of the slow, oxidative type having the greatest concentrations
(10). Taurine can help to protect against cellular dysfunction and oxidant
induced tissue damage (11). Studies also show that it can also help
to preserve healthier mitochondrial function through improved mitochondrial
respiration and ATP production (12, 13 & 14).
Glutamine
Glutamine is a conditionally essential and the most abundant amino acid
in the plasma and muscle of humans (15). Heavy exercise has been shown
to result in reduced plasma glutamine levels, this is most probably
because glutamine is used by cells to provide energy (16). Energy deficits
and post event immune suppression have also been shown to occur when
glutamine levels are low in athletes.
L-Carnitine
Research on the amino acid carnitine has revealed its importance in
mitochondrial energy production and waste management. Carnitine carries
fatty acids from fat metabolism and pyruvate from carbohydrate metabolism
into the mitochondria for aerobic metabolism. It then carries mitochondrial
waste products back into the cytoplasm and helps detoxify organic acids
(17, 18). This amino acid is also important in the modulation of coenzyme
A, another key player in energy metabolism (19). Studies have demonstrated
that carnitine levels in individuals with CFS are lower than in normal
subjects, with carnitine deficiency resulting in muscle energy deficits.
When carnitine levels are depleted over time, the energy deficits can
result in fatigue, myalgias, muscle weakness and post exertional malaise,
all of which are common symptoms of chronic pain and fatigue syndromes.
As carnitine levels begin to rise, these symptoms improve (20).
Selenium and Calcium
Selenium is a vital mineral, which plays an essential role as an antioxidant.
It also serves as a mineral co-factor in the free radical scavenging
enzyme glutathione peroxidase.
It is also important to ensure a healthy balance of calcium and magnesium
in supplementation, as they can compete for absorption. Supplementing
both minerals together is the safest way to avoid any problems arising
from absorption competition.
Synergistic nutrients such as molybdenum, B6, B12 and folic acid are
also effective for improving cellular uptake of magnesium.
