Progesterone: The Brain’s Natural Bodyguard

When most of us hear the word progesterone, we immediately think of its traditional roles in pregnancy, the monthly cycle, or perhaps protecting the uterus during hormone replacement therapy. But for women navigating the perimenopause and menopause, this hormone is far more than a reproductive tool. In my practice, I often describe progesterone as the bodyguard of the nervous system. New clinical research is confirming what many women have been reporting for years: progesterone is a powerful neurosteroid. This means it isn’t just a passenger in the bloodstream; it is a hormone that is actually utilized and sometimes produced directly within the brain to protect, calm, and repair our grey matter.

The most common complaint I hear during the menopause transition is the 3:00 AM wake up. It is a specific kind of insomnia where you aren’t necessarily stressed, but your brain simply feels turned on and refuses to go back to sleep. When you take micronized progesterone, the form identical to what the body makes, your liver converts it into a vital metabolite called allopregnanolone. This molecule is remarkable because it can cross the blood-brain barrier and plug directly into your GABA-A receptors. GABA is your brain’s primary off-switch. It is the neurotransmitter responsible for inhibiting overactive neurons. By enhancing this off switch, progesterone acts as a natural, mild sedative. It reduces sleep latency, which is the time it takes to fall asleep, and significantly cuts down on wake after sleep onset; those frustrating middle of the night interruptions.

Unlike many pharmaceutical sleep aids, progesterone doesn’t just knock you out. It supports Stage 3 slow wave sleep. This is the restorative phase where the body repairs tissue and the brain’s glymphatic system clears out toxins. Most women find they wake up feeling truly refreshed rather than experiencing a morning hangover. Beyond sleep, progesterone acts as a natural bodyguard for your brain cells. We often discuss systemic inflammation in terms of joint pain or heart health, but neuroinflammation is a major player in the brain fog and memory lapses associated with aging.

Progesterone and its metabolites have been shown to support brain health by helping regulate the activity of microglia, the brain’s immune cells. Rather than suppressing the immune system, progesterone appears to promote a more balanced, less inflammatory state. It also supports mitochondrial function and helps reduce oxidative stress, which may contribute to its neuroprotective effects.

This protective effect may also extend to the immune system through what is sometimes called the mast cell connection. Many women in their 40s and 50s notice they become more sensitive to certain foods, fragrances, or seasonal allergens. Mast cells are part of the immune system and act as sentries, releasing histamine when they perceive a threat. Hormonal changes during this stage of life can influence how reactive these cells become. Progesterone appears to have a calming effect in some cases, helping to support a more balanced response rather than an exaggerated one. When mast cells are less reactive, symptoms such as itchy skin, rashes, digestive upset, or that “wired” feeling may be reduced.

As we age, we aren’t just losing a reproductive hormone; we are losing a vital component of our brain’s security system. If you are struggling with sleep or anxiety, it may be time to look at progesterone through this much wider lens.

Protein Power: Your Ally in Aging Gracefully and Staying Strong

When it comes to healthy aging, protein is like the unsung hero of nutrition—always there, quietly working behind the scenes to keep your muscles strong, your brain sharp, and your body resilient. But how much protein do you really need, and is it possible to have too much of a good thing? As a naturopathic physician with a focus on nutrition and healthy aging, these are questions I commonly get from my patients. So, let’s dive into the science and myths of protein and how it can help you stay fit and vibrant at any age.

First, let’s get the numbers straight. The science says that most adults benefit from consuming 1.2 to 1.6 grams of protein per kilogram of body weight daily. Calculate your protein requirements using your estimated lean body weight. For a person whose lean weight is 150 pounds or 68 kg, that’s an average of 26-36 grams of protein three times a day. Considering that one chicken breast has about 50g of protein, those numbers aren’t out of reach for most people.

Dietary protein supports maintaining and building muscle, which plays a vital role in balance, strength, blood sugar regulation, metabolic health, and more. After 50, we typically lose 1% of our muscle mass per year; after 70, that number goes up to 4%. However, exercise and protein intake can reverse that trend. And if you’re trying to build or maintain muscle, a post-workout protein shake isn’t just trendy—it’s genuinely effective. While there’s no need to obsess over a narrow “anabolic window” after exercise, having protein before or after a workout gives your muscles the building blocks they need.

Not all proteins are created equal, though. Animal proteins like chicken, eggs, and dairy tend to pack the biggest punch when it comes to essential amino acids, especially leucine—the star amino acid that triggers muscle growth. But if you’re vegetarian or vegan, don’t fret. By consuming a variety of plant-based proteins, like beans, soy, quinoa, and lentils, and perhaps adding a plant-based protein powder, you can absolutely meet your needs.

What about concerns that high-protein diets might harm your kidneys or speed up aging? For most healthy people, these fears are more myth than fact. Research shows that regular exercise changes how the body processes protein, directing its benefits to where they’re needed most—your muscles and brain. Staying active essentially turns protein into a tool for health, not harm.

Now, let’s tackle a common concern: IGF-1, a hormone that spikes with higher protein intake. Some studies suggest this could increase cancer risk, but here’s the nuance: exercise flips the script. Physical activity directs IGF-1 to muscle repair and brain health while limiting its availability to potential problem areas. Simply put, a balanced diet paired with regular movement lets protein do its job without unintended consequences.

Ultimately, the magic of protein lies not just in what you eat, but in how you live. Pairing a thoughtful protein intake with resistance training or even a daily brisk walk can help keep your body strong and your mind sharp. After all, isn’t that the goal of healthy aging; staying active, independent, and ready for life’s adventures?

So, whether you’re whipping up a protein-packed smoothie, enjoying a hearty lentil soup, or indulging in a grilled salmon dinner, remember every bite is an investment in your future. Protein isn’t just for athletes or bodybuilders; it’s for anyone who wants to age gracefully, stay fit, and feel amazing in their skin. Cheers to that.

 Shining a Light on Healing

Over the past twenty years in practice, I have had the privilege of watching many different therapies help people recover from injury and chronic pain. One therapy that has gained increasing attention over the past decade is Low Level Laser Therapy, sometimes called cold laser therapy.

Despite the sophisticated name, the principle behind it is surprisingly simple. Healing happens at a microscopic level. Inside each of our cells are structures called mitochondria. You can think of them as tiny power plants that generate ATP, the energy currency our cells need to function and repair themselves.

When tissue is injured or inflamed, these cellular power plants often slow down. With less available energy, healing can stall. This is one reason why aches and pains that begin with a small injury can linger for months or even years, long after the original event has faded from memory.

Low Level Laser Therapy works through a process known as photobiomodulation. Plants use sunlight to create energy through photosynthesis. In a similar way, human cells can absorb specific wavelengths of light and convert them into usable energy.

When a carefully calibrated therapeutic laser is applied to injured tissue, those light photons are absorbed by the mitochondria. In essence, the therapy helps support cellular energy production. With more ATP available, cells are better able to clear inflammatory byproducts and rebuild healthy tissue.

Pain often persists because the body becomes caught in a chronic inflammatory loop. The original injury may be long past, yet the surrounding tissues remain irritated and sensitive. Light therapy can act as a gentle biological nudge, helping restore normal communication between the nervous system and the immune system so that the healing process can move forward.

For example, someone with persistent shoulder pain who has tried rest and physiotherapy may find that progress has plateaued. In these situations, supporting the tissue at a cellular level can sometimes help shift the healing process.

This is particularly relevant as we move through our fifties, sixties and beyond. With age, circulation to smaller tissues declines and collagen production slows. These changes contribute to common conditions such as osteoarthritis, tendon injuries and degenerative disc problems. The body still knows how to repair itself, but sometimes it benefits from additional support.

By stimulating micro-circulation and supporting the activity of repair cells, light therapy can help create a healthier environment for connective tissues. In a broader wellness plan, it becomes one of the non-invasive tools that may help maintain joint health and mobility over time.

In clinical practice, Class 3B lasers are among the most widely studied forms of therapeutic laser. They deliver light energy without producing heat, allowing the tissue to absorb the precise photonic dose needed to stimulate healing while maintaining an excellent safety profile.

Placebo-controlled clinical trials have shown that Low Level Laser Therapy can be helpful for several common conditions, including osteoarthritis of the knee or hand, chronic low back pain, tendon injuries such as rotator cuff or Achilles problems, neck pain related to posture or whiplash, and certain forms of nerve pain. As with any therapy, results can vary, and it tends to work best as part of a broader plan that may include movement, nutrition and other treatments.

For many people, it becomes one more way to help the body do what it was designed to do all along: repair itself. Sometimes healing simply needs a little more light.

 Blood Sugar Hacks

As a naturopathic doctor, I often see patients who don’t realize that their daily ups and downs in
energy, mood, and cravings are rooted in something deceptively simple, blood sugar instability.
You don’t need to have diabetes for your blood glucose levels to impact how you feel. In fact,
even subtle fluctuations, common in people who think they’re eating “normally,” can interfere
with hormonal balance, mental clarity, sleep quality, and long-term disease risk.

Your brain is particularly sensitive to changes in blood sugar. When levels rise too quickly, such
as after a muffin and latte breakfast, the body releases insulin to bring things back down. But
when they drop too low, as often happens after a spike, you might feel irritable, foggy, shaky, or
anxious. Many people reach for more caffeine or sugar at this point, and the cycle continues.
Over time, this pattern can contribute to insulin resistance, inflammation, and burnout. In fact,
managing blood sugar is one of the keys to maintaining a healthy mind and body as you age.
So how do we break this cycle without cutting out all carbohydrates or living on salad and
chicken? Here are several evidence-informed strategies I use with patients to help them regain
stable energy and focus, reduce cravings, and support long-term metabolic health, without rigid
food rules.

1. Eat your food in the right order
Research shows that eating vegetables first, then protein and fat, and saving starches and sweets
for last can significantly reduce the glucose rise after a meal. This simple shift in meal
sequencing helps moderate insulin release and keeps energy levels steadier.

2. Start the day with protein
A high-protein breakfast, such as eggs with greens and avocado or a smoothie with plant-based
protein powder and chia seeds, can anchor your blood sugar for the day and prevent the mid-
morning crash that often leads to poor food choices.

3. Move after meals
A short walk, even 10 to 15 minutes, after a meal helps your muscles use up glucose, lowering
the spike and easing the burden on your pancreas. It is also a great way to clear your mind and
reduce stress, which itself can raise blood sugar.

4. Use vinegar strategically
A tablespoon of apple cider vinegar diluted in water, taken before a carbohydrate-rich meal, can
blunt the post-meal blood sugar rise. This is not a magic fix, but for many of my patients, it is a
practical tool that makes a noticeable difference in how they feel after meals.

5. Don’t fear carbohydrates, pair them
Instead of cutting carbohydrates entirely, pair them with healthy fat, fiber, or protein. For
example, instead of eating an apple on its own, have it with almond butter. This slows digestion
and makes the glucose load easier for your body to manage.

In my practice, I offer blood sugar testing, as well as more advanced assessments of insulin
function that can detect subtle imbalances long before diabetes develops. Testing fasting insulin,
insulin after a meal, glucose curves, and related markers can reveal patterns of impaired glucose
tolerance that are often missed by standard blood tests. This allows us to intervene earlier, using
nutrition, lifestyle, and targeted natural medicine to restore metabolic balance before it becomes
a diagnosis.
Stabilizing blood sugar is not just about weight or diabetes prevention, it is about daily quality of
life: your energy, your mood, your ability to think clearly and sleep deeply. You do not have to
overhaul your entire diet, just get smarter about when, how, and with what you eat. Small,
targeted changes can yield powerful results.
