How’s your sex drive?

31st March

Testosterone plays an essential role in the sexual health of both men and women. Although lower than optimal testosterone levels are not the only factor connected to low sex drive, testosterone along with the balance of other hormones are very important in understanding individual concerns with libido. Where women have larger amounts of estrogens to keep a spring in their step, men rely more on testosterone to maintain their mojo. Although there are several supplements that may increase testosterone levels and improve sexual health in men, lifestyle still plays the largest role in maintaining a healthy sex drive and can help support testosterone production well into latter life.

Low testosterone (or low T) has been connected to many different physical and psychological health concerns in men. Notably, low T is more commonly found in men with depression, poor focus/concentration, decreased libido, …



Melatonin and Eczema

26th November

I’m always keen on natural things that help children, but this recent study on melatonin and eczema does warrant some caution.

Melatonin is a naturally occurring hormone that most of us know, when taken before bed as a supplement, helps some people sleep. It is actually also quite a powerful antioxidant that can help repair and protect our mitochondria … the little power plants in our bodies that give us energy. This antioxidant potential is the proposed mechanism in researched support for some cancers.

In most of us, melatonin is produced by the conversion of tryptophan, the infamous turkey sedative, to serotonin during the day and melatonin at night. If we are under a lot of stress, or battling some inflammation or an infection, melatonin production can be highly blunted for the production of a more essential nutrient. Vitamin B3. Along with …



Chronic Pain or Anything …

22nd November

The following article on chronic pain is a true testament to the importance of treating holistically. This neurosurgeon, Dr Hanscom, impressively came up with his own chronic pain treatment method after he was struck with the frustrating reality that spinal surgery has very poor outcomes for patients suffering with chronic pain.

I frequently see people in some degree of chronic pain or suffering from chronic diseases which can have detrimental effects on our mental health. Or is it possible that in reality it is our mental health that is affecting our physical health!

Stress has a major effect on every part of our body and has a dramatic impact on our physical health. With my own recent personal experiments, along with recent feed back from people using heart rate variability (HRV) monitors, this technology allows us to have a greater awareness of …



Environmental Toxins and Pregnancy

5th November

Creating another human being has got to one of the most amazing experiences in life! I commend all of you that have done it.

One thing I see commonly in practice is women worried about environmental toxicity before or during pregnancy and sometimes there concerns are justified.

Living in the most toxic environment humans have ever seen, it’s no wonder people have some concerns about exposures, especially when child development is involved.

The big ones to consider are;

Heavy metals, such as lead, cadmium and mercury, as these have been shown to impair development both in utero and postnatally. Simple sources of exposure are amalgam fillings, fish, cigarette smoke, older paints and pluming, as well as contaminated water sources and some vaccinations.

POP’s or persistant organic pollutants, such as solvents and pesticides, along with other endocrine disrupting agents like parabens and plasticizers  are …



Insomnia?

25th November

Not being able to sleep is the worst feeling ever! Your body is begging you to pass out but your mind is busy trying to solve the worlds problems. Situational insomnia, like staying in a hotel room or arguing with a loved one, can sometimes be unavoidable. Restless sleeps night after night however, is the body’s way of telling us that something is wrong. 

What many people don’t understand is that hormones control our sleep cycle and our sleep cycle helps control many of our hormones. This, in part, is why chronic insomnia is a major risk factor for a lot of health concerns like cancer, heart disease, and diabetes.

One of the biggest causes of insomnia is stress. The stress hormone cortisol can pretty much explain sleep disturbances in most people. Sometimes, the challenge is trying to find out where the elevated …



Hormones – All about Balance

21st October

Guidelines for hormone use are ever changing, but the best answer when considering the treatment of hormonal balance, seems to be based on the individual. When it comes to using “bioidentical hormone replacements” or nutritional and/or dietary support, many factors should be considered to provide the best and safest possible treatment. Whether we are talking about pre-menstrual symptoms, fertility concerns, breast cancer, cervical, uterine, or ovarian concerns, the individuality of hormone balance is related to many different factors. Stress levels, likely have the most devastating effect on hormone balance, however liver and bowel function should not be overlooked.

One major impact of stress is through a functional reduction in the sex hormone progesterone because progesterone is one way our bodies can make the stress hormone cortisol. Essentially, when we need more cortisol we can steel progesterone to make it. Cortisol levels …
