Muscle Cramp/Tension Formula by Pure Encapsulations:  Harnessing Nature's Power to Calm the Mind, Relax the Body, and Support Blood Pressure

Stress and physical fatigue are common ailments that many of us face, often manifesting as muscle cramps, tension, poor sleep quality, anxiety, and even hypertension. Recognizing these challenges, Pure Encapsulations has crafted a holistic solution aimed at not only alleviating these symptoms but also enhancing overall well-being. Their "Muscle Cramp/Tension Formula" is a meticulously designed supplement that harnesses the therapeutic benefits of key ingredients known for their calming and relaxing properties. Let's delve into the science behind each component and discover how they collectively work to combat stress and promote a harmonious bodily function.

Passion Flower

Passion flower is a botanical known for its sedative effects, traditionally used to alleviate anxiety and improve sleep. Clinical trials, such as one published in Phytotherapy Research, have documented passion flower's efficacy in managing generalized anxiety disorder, making it a valuable ingredient for stress relief and mental well-being (Phytotherapy Research, 2001).

Passion flower is not only good for calming the nerves but it might also help in keeping blood pressure in check. This flower has a long history of being used for its relaxing effects, and research is showing it could even help with high blood pressure and anxiety. A study found that passion flower could be a useful natural option for dealing with these two health issues together (source).  This makes passion flower a powerful ingredient in the "Muscle Cramp/Tension Formula" by Pure Encapsulations.

Some experiments, particularly on rats, showed that extracts from the passion flower could lower blood pressure. Scientists think this might be because passion flower has certain substances that relax the body and help control blood pressure.

Lemon Balm

Lemon balm, often praised for its calming effects, is used to ease nerves and anxiety, support sleep, and even improve cognitive function. A study in Phytomedicine indicated that lemon balm could significantly increase calmness and alertness in adults, showcasing its potential in managing stress and enhancing relaxation (Phytomedicine, 2004).

It appears that this lemon balm may also have potential benefits in managing blood pressure.

According to a study highlighted by Examine, lemon balm's stress-reducing properties may also assist in lowering blood pressure in individuals with essential hypertension, a condition when high blood pressure has no identifiable cause. This research was a randomized controlled crossover trial in which 49 individuals with essential hypertension (average age of 60) consumed either 1,200 milligrams per day of lemon balm (hydroalcoholic extract) or a placebo for a four-week period.

The findings of this study suggest that when compared to the placebo, the lemon balm extract reduced both systolic and diastolic blood pressure, regardless of the sequence of the interventions (source).


Chamomile is a well-known herb utilized for its anti-inflammatory, anti-anxiety, and cramp-relieving properties. Its application in treating symptoms of generalized anxiety disorder has been backed by research published in the Journal of Clinical Psychopharmacology, further affirming its role in the formula for soothing nervous tension and promoting tranquility (Journal of Clinical Psychopharmacology, 2009).

One chamomile's less explored yet potent benefits lies in the potential to alleviate hypertension. Research published in the journal Pharmaceuticals has indicated that chamomile, acts as an anti-hypertensive agent (Pharmaceuticals, 2022). This confirms the potency of chamomile in effectively managing blood pressure levels, making it an essential ingredient in the Muscle Cramp/Tension Formula. This feature, combined with its proven effects on generalized anxiety disorder, reiterates its value in promoting relaxation and tranquility in the users. Several patients, from Dr. Phelts' practice, experiencing high blood pressure reported noticeable benefits using this supplement, solidifying its real-world efficacy.

Remember, as with all dietary supplements, it's essential to consult with a healthcare provider before starting a regimen, particularly for those dealing with a health condition like hypertension.


Calcium is widely celebrated for its crucial role in bone health, but its benefits extend far beyond. It plays a pivotal role in nerve transmission and muscle contraction. 

A study reviewed several trials involving people who were given calcium supplements compared to those who were not, and the findings were promising. Although no one in the study developed high blood pressure, those who took calcium supplements had a small but significant decrease in their blood pressure. The effects were seen in both men and women and were consistent regardless of how much calcium the participants were already consuming from their diet (source).  While the reduction was modest, even small changes can have a big impact. For instance, lowering your systolic blood pressure (the top number) by just 2 mmHg could help reduce the risk of stroke by 10% and heart disease by 7%.


Magnesium is another mineral vital for its role in over 300 enzymatic reactions, including muscle and nerve function, as well as energy production. Research indicates that magnesium can help alleviate muscle cramps and is essential for muscle relaxation. 

Magnesium isn't just essential for keeping our muscles operating smoothly – it might also help manage your blood pressure. In fact, research indicates that adopting a diet high in magnesium or taking magnesium supplements can potentially lower blood pressure.

Research conducted on 60 patients with hypertension found that after consuming magnesium oxide for 8 weeks, there were significant reductions in their measured blood pressures. On average, the standard office blood pressure measurements fell by 3.7/1.7 mm Hg, 24-hour ambulatory blood pressure was reduced by 2.5/1.4 mm Hg, and home blood pressure decreased by 2.0/1.4 mm Hg. The study found that those with the highest initial blood pressure readings experienced the greatest reductions (source).

Moreover, another study has supported magnesium's benefits. It found evidence that magnesium intake can reduce the risk of stroke and might help control diabetes and lower blood pressure in adults. The study noted these benefits seem to be amplified when a person consumes a diet high in magnesium (source).

According to the Cleveland Clinic, magnesium may potentially help manage anxiety symptoms by moderating cortisol, the stress hormone in our body. Too much cortisol can intensify anxiety, and magnesium can help control this by reducing the pathways that trigger this hormone in the brain. This could be beneficial for those struggling with chronic stress (source).

In addition, magnesium can also help regulate neurotransmitters in your brain, which manage the "on and off" switches of the brain. It does this by reducing the effect of the excitatory neurotransmitter, glutamate, and helping release GABA, the inhibitory neurotransmitter. This delicate balance is crucial to control our stress and anxiety responses.

Interestingly, a potential magnesium deficiency could contribute to your anxiety levels. Studies from a decade or so ago indicated that about 70% of Americans might be deficient in magnesium. Some people with mild anxiety may find their condition improves after supplementing with magnesium.

While these potential benefits are promising, do remember that maintaining mental health involves a holistic approach and merely banking on supplements like magnesium may not be enough. It is always recommended to discuss any new supplement intake with your healthcare provider.


Potassium plays a crucial role in maintaining normal muscle and nerve function, thus regulating muscle contractions and preventing cramps. A study has shown that potassium can also aid in managing hypertension, a common stress-related condition (source).
