Mini Pause #19: Eating High Protein? Add Collagen to Balance Amino Acids

Keep an Eye on Methionine and Glycine; They Affect Body Composition & Emotional Well-Being


Higher protein consumption is essential as we move through perimenopause and menopause. We should be mindful, however, of balancing the amino acids we take in through a variety of protein sources. Specifically, we want to think about our methionine-to-glycine ratio

Today, I discuss these amino acids, where they are abundant, and the products you can take to keep them in balance. 


Methionine and glycine are two amino acids that profoundly impact your body composition and emotional well-being. These two changes are inexplicably intertwined and exacerbated in perimenopause. Methionine and glycine are crucial in maintaining your muscles, joints, and connective tissues, and to help you heal when you’re injured. They’ve both been shown to help with type 2 Diabetes, cardiovascular disease, and stroke–all of which are diseases of aging and poor metabolic health.

Striking the right balance will help keep your hair lustrous, build muscle, regulate blood sugar, help quell anxiety, and keep your faculties sharp.


Methionine is an abundant amino acid in meat, eggs, chicken, and fish. We typically associate these foods with “high protein.” Methionine also is implicated in several metabolic processes including endogenous creatine synthesis, glutathione synthesis (the master antioxidant in the body), and DNA methylation. 

However, consuming only foods high in methionine can deplete your glycine levels.

Glycine has been shown to stabilize blood sugar levels, keep your hair shiny and thick, and promote collagen and elastin production in the skin. All things we would like to continue to have in our 40s and 50s, thank you very much!

You want adequate levels of BOTH methionine (derived largely from an animal’s muscle) and glycine (derived largely from an animal’s skin, bones, and connective tissue). 

So, how much of each should we be aiming for?

If you want to build muscle and are actively lifting weights in the ways I’ve described in previous newsletters, consume approximately 1g of protein (in this case, methionine-rich foods) per ideal pound of body weight. This is a good place to start. The 1g of protein can be considered your muscle meats (aka the methionine-containing products) and you will most certainly consume adequate amounts of methionine.

The question then becomes: “What about glycine?”


We know our ancestors, through nose-to-tail consumption of animals, consumed way more glycine than we do now in modern life. 

The “meat” we consume today is often just the muscle of the meat, and we often discard the bones, the fat, and the organs. I’m guilty of this too. I can make a pretty mean stock from chicken bones and a great bone marrow, but that is the extent of my organ-making skills. I consume liverwurst as my “organ” because I just can’t stomach eating the actual liver, heart, kidneys, and other things that are in liverwurst. 

  • If you are eating an animal-based diet, for every 10 grams of animal (muscle) protein you consume, you can add 1 gram of glycine in the form of collagen protein, bone broth, or glycine supplements. This would be a 10:1 ratio. For example: If you’re eating 150g of animal (muscle)–based protein daily, you want to consume 15g of collagen protein. 
  • If you are eating a plant-based diet, your glycine intake is already naturally higher, as plant-based proteins tend to have more glycine. I recommend adhering to the 10:1 ratio here, as well.

The best sources of glycine are going to be bone broth, hydrolyzed collagen powder, glycine supplements, gelatin, and even edible bones (like in your can of sardines). 

My main source of glycine comes from collagen powder: I use mindbodygreen’s Beauty & Gut Collagen powder or Equip Foods’ Grass-Fed Collagen. The benefit of collagen powder is that it is superior to collagen synthesis than taking a pure glycine supplement. So I always opt for collagen powder or bone broth over taking a glycine supplement. 


  • Ensure you are balancing your methionine intake with glycine by supplementing with 1g of glycine for every gram of methionine intake
  • Pick up a bag of hydrolyzed collagen powder like Equip Foods or mindbodygreen. Or, you can make or buy bone broth, or glycine powder. (If you try Equip or mbg, click the links and use code DRSTEPHANIE for a discount.
  • I add one scoop of collagen powder to my workout drink–it’s flavorless and dissolves completely in water.

Question of the Week

Q: Do you prefer to work out alone or with your partner? 

Thanks to Lazgrrl on IG for asking this question. The short answer? I think it depends on what I am working on! 

On leg days, I usually work out by myself simply because my husband doesn’t train glutes in the same way I do. I’m doing large volumes of glute training, and we often are not using the same machines. I also need to dig deep psychologically for leg day, which means I need my music, and I don’t want to talk. 

On back days, I love to train with my hubs because we work the same muscle groups in similar volumes. The same goes for shoulders! 

Cardio is the absolute hardest thing for me to get in consistently and I’m inclined to skip it, so I like to have a cardio partner. My husband is particularly gifted with sprinting! It’s a challenge for me to try and keep up with him (I don’t). 

What I Recommend: CollaGenius

There’s a new collagen product that I tried and I have to say, I’m wholly impressed with CollaGenius. It differs from other formulations because it combines hyper-concentrated forms of Lion’s mane, Chaga, cordyceps, and reishi mushrooms with the collagen. Then, in a brilliant taste move, adds Peruvian cacao!

This formula targets your brain for maximum energy, focus, and performance. It also improves skin elasticity and helps alleviate stress. I like to mix it with my morning cappuccino to transform it into a mochaccino with benefits. It’s also great in smoothies and even just with water.

After each serving of CollaGenius, you’ll feel calm and energized. I noticed a difference right away. You get antioxidants, mood support, and improved brain function. It’s a good fit for my Bettys struggling with peri & meno symptoms like brain fog.

How Minerals Slow Down Aging

I talk a lot about how you can feel (and look) amazing at any age. As women, we’re often taught to fight against our bodies, but it’s incredible how much can change when instead, you start supporting your body.

A few simple shifts in your daily habits can make you look 10 years younger—and add 10 years to your life.

One of the easiest changes you can make is to add full-spectrum minerals to your routine. Every single cell in your body relies on minerals, and they play an essential role in everything from hormones to metabolism to brain function. The sad fact is that, since most of us are mineral-deficient, many women struggle to maintain healthy function in these areas.

Here’s a quick look at how minerals can nourish your body and help you look and feel your best, especially as you age.

Why Do Minerals Matter for Aging?

Minerals play an essential role in almost every major biological process in your body. They’re involved in:

  • Hormone production (especially estrogen, progesterone, and thyroid hormone synthesis)
  • Fat burning (your metabolism slows if you don’t have enough minerals)
  • Food cravings (cravings are often a sign of mineral deficiency)
  • Sleep (you won’t create melatonin, your body’s sleep hormone, without adequate magnesium and potassium)
  • Stress response (mineral deficiencies make you more reactive to cortisol)
  • Mood (minerals make up the neurotransmitters that regulate your emotions)
  • Mental clarity, memory, and other aspects of brain function

Minerals also are essential to mitochondrial function (energy production), which is important in aging. Your mitochondria are the power plants of your cells: they make ALL the energy that keeps your body alive.

As you get older your mitochondria struggle to produce energy. [*] Your metabolism slows, collagen production in your skin decreases, you feel fatigued more easily, your body struggles to manage inflammation, and so on.

One of the biggest drivers of mitochondrial decline is a lack of minerals. [*] Your body needs more minerals as you age, and if you don’t get them, your mitochondria begin to break down.

As a result, you age much faster when you don’t have enough minerals. [*] They’re essential to keeping your cells young and your body healthy.

The trouble is that almost everyone needs more minerals. A 2022 study from the CDC found that 97% of Americans are mineral-deficient. [*] We’re all aging a lot faster than necessary!.

Support Your Body with Minerals

The good news is that replenishing your minerals is easy. The right supplement routine will refill your mineral stores and support your mitochondria. That allows you to slow down aging and help your body to work better than it has in years.

In the past, replenishing your minerals meant taking a cabinet full of individual supplements: magnesium, potassium, zinc, calcium, iron, manganese, and so on.

That’s why I was so happy to find BEAM Minerals. They offer a full-spectrum liquid supplement that provides all the minerals your body needs, in the right ratios, with close to 100% bioavailability.

You can take a one-ounce shot of liquid in the morning (don’t worry; it tastes like water) and refill all your mineral stores at once.

BEAM Minerals also contain flavonoids that deliver mineral cofactors directly to your mitochondria, which makes them especially good for anti-aging. They help your mitochondria get stronger as you age, not weaker.

The best part is how easy BEAM makes it. In 30 seconds a day, you can refill all your body’s mineral stores at once, nourish your cells, and access a younger, brighter version of yourself.

If you decide to give BEAM Minerals a try, make sure you enter BETTER at checkout for 20% off your first order.

And however you choose to do it, I highly recommend finding a good mineral supplement. Minerals make a night-and-day difference in the aging process, and taking them is one of the simplest things you can do to look and feel your best.

With one shot of liquid in the morning, you can replenish every essential mineral your body needs!

It takes just 30 seconds, and you’ll feel the difference in your energy, focus, and more. Head to BEAM Minerals and use code BETTER for 20% off.

Mini Pause #8: Make the Change to Zone 2 Cardio Training

Zone 2 Training for Energy Heart Health & Metabolic Flexibility

TL,DR (too long, didn’t read)

Much ado has been made about the ideal zones for training. But, as usual, there’s often a gap in evidence to demonstrably show that these sweeping recommendations are also appropriate for women in perimenopause and menopause.

Estrogen, our metabolic superheroine, keeps us insulin-sensitive when we are younger, but as this dwindles in perimenopause and menopause, we should be thinking about Zone 2 as a protective activity for heart health and a way to keep us metabolically flexible.


The big question I want to answer here is “Why should perimenopausal and menopausal women care about Zone 2 in the first place?”

Simply, as a woman over 40, you want to double down on cardiorespiratory fitness, and Zone 2 trains up mitochondrial function, health, and density. This is going to maximize your capacity to produce energy.

You know the days where you are absolutely bagged and your teenager comes home with drama, the laundry room has clothes piling up on top of the washer, there are seven glasses of water on the counter despite only having two children, the dishwasher needs to be emptied and you still need to find time for your skincare routine, a social life, save money for retirement, and deep condition your hair?

Zone 2 won’t solve these problems, but it will certainly increase your capacity for energy production to help you navigate your to-do list.

Zone 2 also helps to sensitize our muscles to both insulin-dependent and insulin-independent glucose uptake. Said another way, it makes you more carbohydrate sensitive which is something we tend to lose as we age.

It helps to combat inflammation and reactive oxygen species (ROS) and generally slows the aging process.


Most exercises are defined into zones based on muscle fiber recruitment and whether the energetic demand is aerobic or anaerobic.

As the energetic demand for activity increases, we will move from burning fat to burning some fat and some carbs to exclusively burning carbohydrates. As the demand increases, your body will turn to glucose for its fuel.

When we think about fiber type distribution, there are differences between men and women. Women typically have a greater distribution and area percentage of Type 1 fibers (“slow twitch”). Men typically have bigger cross-sectional diameters of all fiber types and have more Type 2 fiber types (“fast twitch”).

This is not to say men have MORE Type 2 fibers than women, but that the diameter of our Type 2 fibers is smaller so that the whole body percentage tips towards Type 1. This can certainly be one (of many) reasons why men can exhibit greater muscle strength and power compared to women, and women typically demonstrate greater muscular endurance.

Some have looked at this data and suggested that this means women need less Zone 2 training than our male counterparts. While I think this is true for women in their fertile cycling years, I do think perimenopausal and menopausal women are a cohort unto themselves. Women in their cycling years may need less Zone 2, but as you creep into perimenopause and menopause, your needs change.

As we navigate perimenopause and menopause, we absolutely need to be training up our capacity for Zone 2 AND because our Type 2 fibers are smaller in diameter, we need to also prioritize resistance training and sprinting (in Zones 5 or 6), both of which are anabolic to Type 2 fibers. Sprinting and resistance training will most certainly be topics for future Mini Pause newsletters!

The primary argument that women are better at fat oxidation than men is largely due to estrogen levels. Estrogen has major implications on our metabolism because it helps to sensitize the whole body to insulin. This fundamentally changes in menopause where we see estrogen levels fall off a cliff to one percent of their previous levels. This means that metabolic derangements like insulin insensitivity, Type 2 Diabetes, visceral fat accumulation, dyslipidemia, and weight gain around the abdomen are rampant in menopausal women, despite no changes in their lifestyle habits.

If you want a deeper dive into body composition changes during menopause, read issue 6 of the Mini Pause.

In essence, we lose our metabolic superpowers and now, in menopause, have to work to stay metabolically flexible.

Zone 2 training can serve as a foundational tool to help improve insulin sensitivity. As you get stronger, your power and work output will also continue to increase. You’ll be able to do more work and sustain a higher heart rate in zone 2 as you get better at it.


Ideally, you can do a Functional Threshold Power test on a bike and multiply this by 80% to get your Zone 2 number. You can read more about FTP here if you’re a nerd or have a champion attention span for details.

I have used my Carol Bike’s 20-minute FTP test to determine my Zone 2 levels and now retest this once a quarter. I like the bike because it is AI-based and calculates my resistance and watts for me–I don’t have to think about it!

If you don’t have an FTP test available to you, you can also crudely measure heart rate by using Phil Maffetone’s MAF equation: 180 minus your age. Then, multiply that number by 80% and that is your baseline HR to aim for.

In full transparency, I do find this equation slightly underestimates my heart rate. Remember, as you get fitter through Zone 2 training, you can work at a higher heart rate and workload. Nonetheless, it’s a good metric to start with.

You can do Zone 2 on any cardio machine as long as you have your target heart rate and stay there. Rucking (walking with a weighted vest or backpack), salsa dancing, or twerking all can get you in that Zone 2 sweet spot. And who doesn’t want to be twerking on the regular?

For my Type A Bettys who don’t think they’ve worked out unless they go max all out, take note: that isn’t Zone 2! I often joke that my toxic trait is being unable to stay in Zone 2 because it barely feels like a workout.

I’m sweating…sort of.
I’m breathing heavier….sort of.

If you can still have a conversation or nasal breath through the workout–but you’re working hard enough that you would prefer not to do either–you’re doing it correctly.

The next question is how often should you be doing Zone 2 work? This is going to depend on how conditioned you are. A beginner to Zone 2 might start at 30 minutes, three times a week, and each week, aim to ramp up the time by a few minutes per session.

Ideally, I would love to get everyone up to a baseline of about 45 minutes, three times weekly. The 45-minute mark is where the mitochondrial magic happens.

There are a few ways I get my Zone 2 training:

  • Most of it is on my Carol Bike, and I aim to get in two longer sessions of about 75 minutes during the week. (If you check out the bike, use code DRSTEPHANIE for a discount.)
  • I recently started yoga and have been doing a few Vinyasa classes per week. I wore my heart rate monitor a few times and, as I suspected, my heart rate was in that sweet spot for Zone 2.


  • Look at your calendar and see where you might be able to fit in three, 30-minute Zone 2 workouts this week:

-Could you tack it onto a time you are already at the gym?

-Do you like to watch TV at the end of the day? Could you do that with a treadmill and a weighted vest or a stationary bike?

  • Start this week with one 30-minute session. Put it on your calendar right now.
  • Next week, add in two minutes until you are comfortable and able to do 45 minutes at your Zone 2 heart rate.
  • As you monitor your heart rate, you should see, over an eight- to 12-week period, where the intensity of your workout becomes “easier.” You may even notice your heart rate doesn’t get up as high. This is a great sign! It means going ahead and making the workload a little harder. Up your speed, watts (if on a bike), or incline on a treadmill to challenge yourself.
  • Now high-five yourself and your heart for adaptation!

Question of the Week

Q: How do you cope with feeling like you’re losing your youthfulness?

To Kristen in the Bettyverse, thank you for asking what many of us have felt at one time or another.


I think aging and the feeling of losing your youthfulness force you to contend with your mortality. I think about death probably more than the average person, and I try to contrast it with the life I currently have.

Most of us never thought about the totality of our lives when we were in our 20s and 30s. And yet, in our 40s this thought that we might not be here forever begins to stir and frequent our thoughts more often.

A part of life is death.

And despite the speed at which science is progressing, I think most of us are going to have somewhere around 80 or 90 great years in us. Maybe slightly more, maybe less, but this is a reasonable estimate.


So if you’re 40-something and starting to feel like your better years are behind you, what does that mean?

First, consider why you so heavily place weight on youth:

  • Is it your youthful beauty you are mourning?
  • Your lack of responsibilities like mortgage payments?
  • Your ability to travel without kids?
  • Or does the brain select only the positive aspects of your youth and forget the rest in the name of nostalgia?

Maybe your skin was plumper 20 years ago, but with age, a different kind of beauty emerges.

The beauty of being comfortable in your skin, the unhitching of who you THOUGHT you should be with just being who you ACTUALLY are.

The wisdom and experience of your life can now work harmoniously with the intuition you likely ignored when you were younger. Decision-making gets easier. You fight for yourself rather than sacrifice yourself at the altar of others’ desires. You spend time with people you truly enjoy being around.

As for the aesthetics… sure, our melanocytes are not producing pigment in our hair anymore, and the elasticity of our eyelids is not what it once was. But that is the privilege and gift of aging.

I’ll repeat it for emphasis: That is the privilege and gift of aging.

It is a privilege to watch your children grow up.
It is a privilege to become a grandmother.
And it is even a great privilege to die with people around you who love and revere you.

A life well lived is one where your time is spent without the shackles of what you think you should do and how you think you should act. Forget what society tells you should be. Age brings the ultimate gift of “you do you, boo.”


For me, the prospect of aging is more about the time and impact I want to make.

  • I have a gift and I want to share it with as many of you as I can.
  • I’m not going to spend any more time hiding because I fear judgment or criticism from others. I have no time for that!
  • In my 40s, I know what I am capable of, who I am, who I am not, and how to remember who I am when I have temporarily forgotten.

And if we’re just talking about loss of youthfulness: grays can be covered, and skin creams and cosmetic procedures can be applied to make you look younger.

If you don’t become MORE of who you already are, the loss of youthfulness doesn’t matter as much because you’re still warring with yourself internally.

Maybe a soliloquy on mortality wasn’t what you were expecting with this question, but I hope this helped redirect what it means to age, and how lucky you are to do it.


I’ll be answering your questions every week right here in the Mini Pause! Let me know what’s on your mind. I’ll be checking for both questions and feedback at


It’s almost impossible to get all your minerals from food alone. And many of us are experiencing that deficiency in the form of chronic health issues like fatigue, muscle cramping, anxiety, hair loss and imbalances with adrenals, hormones and blood sugar. In my case, it was hair loss and chapped lips.

It was only when I started supplementing with minerals and electrolytes that I noticed a substantial slow down in hair loss and my lips are not peeling anymore.

I use BEAM Minerals daily. It’s so easy to just pour a capful and throw it back. It tastes like water and is a powerful system detoxifier, removing mold toxins, heavy metals, and pesticides.
