Perhaps your leg cramps are waking you up at night?
Maybe you’re a regular exerciser and don’t understand why you aren’t recovering the way you used to?
Maybe you’ve been told that your aches and pains are a normal part of menopause? Or maybe you’re taking a heap of turmeric and glucosamine and other supplements targeted towards women in middle age and older, hoping for the relief that you deserve?
The interview I did with a journalist recently was interesting. She’s writing a book on menopause and wanted to interview me about exercise. “Why don’t you promote high intensity exercise like everyone else does?” she queried.
After listening to my Masterclass on Menopause, she had picked up on this statement I had made. It was an unusual question to start with and made me understand that maybe she hadn’t talked to women who had sore knees, plantar fasciitis, aching joints and who weren’t sleeping.
These exhausted women who continue to workout and don’t understand how their muscles and joints change during their menopause transition are everywhere – perhaps you are someone who can relate?
Women on my own doctoral studies were the same … as I was too.
“Menopause has been so heavily medicalised” I mentioned, “and only viewed through the lens of hot flushes, anxiety and depression. But there’s so much more to it than these concerns.
Our muscles are ageing and for women who exercise, this means that the uptake of calcium into their muscle fibres is slower. As such, this affects the muscle contraction speed and many who come on my programmes complain about aching muscles and restless legs that trouble them at night, keeping them awake. I hear about it all the time as a generation of Personal Trainers and women who have exercised all their lives, go into their 50s” I replied.
The Muscle-Calcium Connection in Menopause:
1200mg a day. Every day.
That’s the amount of calcium we need from our 50’s onwards. But whilst we’ve all been told that it’s to do with our bone health, I beg to differ.
Because if you are a women in her mid-life transition who either exercises regular or you are in a physically demanding job, then your calcium intake is not only about your bones, it’s about your muscles as well.
And yes, I include your heart muscle and the tiny smooth muscles that make up your blood vessels in this comment. They need calcium too. I talk about this in my video below.
Your circulatory system, extracellular fluid, muscle, and other tissues need calcium.
Calcium as a nutrient, is most commonly associated with the formation and metabolism of bone. With over 99 percent of total body calcium found as calcium hydroxyapatite in bones and teeth, it provides hard tissue with its strength.
But whilst the emphasis for women in menopause and post-menopause has primarily been about calcium for bone health, there’s another reason that it’s important.
Calcium is critical for controlling the contraction and dilation of your blood vessels. It’s also crucial for muscle contraction because of its role in helping the nerve electrical current to ‘jump’ across the gap between the nerve and the muscle.
Bone tissue serves as a reservoir for and source of calcium for these critical metabolic needs through the process of bone remodelling. You can guess what happens to your bones if your calcium levels are therefore, low.
Yes, that’s right. The bones deplete calcium to help to balance up the plasma levels so you can do all that exercise or activity that your muscles and nerves are demanding.
It’s not ‘just’ about calcium in food either. Optimal Vitamin D levels are crucial to maintain during your menopause transition too.
In the MyMT™ programmes, I talk a lot about Vitamin D levels and have specific information for women who join me. This is because Calcium metabolism is regulated in large part by the parathyroid hormone (PTH)-Vitamin D endocrine (hormone) system.
A series of feedback loops help in maintaining blood calcium levels depending on Vitamin D absorption. This is why, during vitamin D deficiency, bone metabolism is significantly affected as a result of reduced active calcium absorption into bones, muscles and in our nervous system.
If you aren’t getting enough Vitamin D (and I’ve written how our skin is changing in menopause and Vitamin D absorption is affected too), and you are experiencing weak muscles, poor rcovery after exercise or you have restless legs and muscles cramps at night, then have a serious look at your calcium intake and have a good think about your gut health.
Your colon is the main site of calcium absorption into your body.
This means that poor gut health might affect your ability to absorb calcium from food. If this is the case, then one of your priorities is to sort out gut health. [If you need to learn more, then have I have a gut-health module that can be purchased separately from the 12 week programme as part of my Restoration Series).
Sources of Calcium:
Whilst I have a focus on the traditonal Mediterranean Diet on the MyMT™ programmes, typically this diet is lower in dairy products, especially milk.
That’s why other sources such as oily fish such as wild salmon (which differs in Vitamin D content from farmed salmon), small fish, nuts, legumes, cereals (which are fortified with Vitamin D in some countries) and certain vegetables are an important sources of dietary calcium too.
As I’ve just produced my new MyMT™ Food Guides for the women on the 12 week online programmes, as my focus has been on Vitamin D and Calcium uptake in my coaching group this week, I want to share this list with you here as well.
There are numerous symptoms that women experience in menopause, including restless legs and sore, aching muscles.
But as I always say, the ‘problem’ isn’t menopause – this is a natural event that all women go through. The ‘problem’ is that we need to change our lifestyle to accommodate this incredible stage of life.
That’s what the 12 week online MyMT™ programmes teach you to do – these are differentiated according to whether you desire weight loss or not. I hope you can join me sometime if your symptoms and/or weight, are getting you down.
