How Much Difference Do Probiotic Supplements Make?

There are three main things that get talked about with regard to gut health:

  • Prebiotics (fibrous foods)
  • Probiotics (things containing live “good” bacteria)
  • Postbiotics (things to help them thrive)

Today we’ll be talking about probiotics, but if you’d like a refresher on general gut health, here’s our previous main feature:

Making Friends With Your Gut (You Can Thank Us Later)

What bacteria are in probiotics?

There are many kinds, but the most common by far are Lactobacillus sp. and Bifidobacteria sp.

Taxonomical note:sp.” just stands for “species”. The first name is the genus, which contains a plurality of (sometimes, many) species.

Lactobacillus acidophilus, also written L. acidophilus, is a common species of Lactobacillus sp. in probiotics.

Bifidobacterium bifidum, also written B. bifidum, is a common species of Bifidobacterium sp. in probiotics.

What difference do they make?

First, and perhaps counterintuitively, putting more bacteria into your gut has a settling effect on the digestion. In particular, probiotics have been found effective against symptoms of IBS and ulcerative colitis, (but not Crohn’s):

Probiotics are also helpful against diarrhea, including that caused by infections and/or antibiotics, as well as to reduce antibiotic resistance:

Probiotics also boost the immune system outside of the gut, too, for example reducing the duration of respiratory infections:

You may recallthe link between gut health and brain health, thanks in large part to the vagus nerve connecting the two:

No surprises, then, that probiotics benefit mental health. See:

There are so many kinds; which should I get?

Diversity is good, so more kinds is better. However, if you have specific benefits you’d like to enjoy, you may want to go stronger on particular strains:

  • 5 Exercises That Fix 95% Of Your Problems

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Well, your musculoskeletal problems, anyway! The exercises won’t, for example, do your taxes or deal with your loud neighbor for you. But, they will help your body be strong, supple, and pain-free:

    20 minutes total

    The exercises & what they do:

    • Dead hang: improves shoulder health, decompresses the spine, and strengthens grip. Hang from a bar for 20–30 seconds, progressing to 1–2 minutes.
    • Glute bridge: builds glute strength, improves core stability, and reduces lower back tension. Perform 2 sets of 10–15 reps, with variations like single-leg bridges or added weight.
    • Farmer’s walk: a full-body workout that strengthens the shoulders, core, and grip while improving posture. Walk with weights for 30–60 seconds, 3 rounds, increasing weight or duration over time.
    • Resting squat: enhances ankle, hip, and knee mobility, restoring natural functionality. Hold a deep squat for 20–30 seconds, progressing to 1–2 minutes. Use support for balance if necessary.
    • Thread the needle: improves flexibility, reduces tension, and enhances rotational mobility. Perform slow, controlled rotations from an all-fours position, 2 sets of 10 reps per side.

    Suggested 20-minute workout plan:

    1. Dead hang: 3 sets of 30 seconds
    2. Glute bridge: 2 sets of 10–15 reps
    3. Farmer’s walk: 30–60 seconds, 3 rounds
    4. Resting squat: hold for 20–30 seconds, 2–3 rounds
    5. Thread the needle: 2 sets of 10 reps per side

    It is recommended to perform this routine 3 times per week with 1-minute rests between sets.

  • The Seven Circles – by Chelsey Luger & Thosh Collins

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    At first glance, this can seem like an unscientific book—you won’t find links to studies in this one, for sure! However, if we take a look at the seven circles in question, they are:

    1. Food
    2. Movement
    3. Sleep
    4. Ceremony
    5. Sacred Space
    6. Land
    7. Community

    Regular 10almonds readers may notice that these seven items contain five of the things strongly associated with the “supercentenarian Blue Zones”. (If you are wondering why Native American reservations are not Blue Zones, the answer there lies less in health science and more in history and sociology, and what things have been done to a given people).

    The authors—who are Native American, yes—present in one place a wealth of knowledge and know-how. Not even just from their own knowledge and their own respective tribes, but gathered from other tribes too.

    Perhaps the strongest value of this book to the reader is in the explanation of noting the size of each of those circles, how they connect with each other, and providing a whole well-explained system for how we can grow each of them in harmony with each other.

    Or to say the same thing in sciencey terms: how to mindfully improve integrated lifestyle factors synergistically for greater efficacy and improved health-adjusted quality-of-life years.

    Bottom line: if you’re not averse to something that mostly doesn’t use sciencey terms of have citations to peer-reviewed studies peppered through the text, then this book has wisdom that’s a) older than the pyramids of Giza, yet also b) highly consistent with our current best science of Blue Zone healthy longevity.

  • ‘Sleep tourism’ promises the trip of your dreams. Beyond the hype plus 5 tips for a holiday at home

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Imagine arriving at your hotel after a long flight and being greeted by your own personal sleep butler. They present you with a pillow menu and invite you to a sleep meditation session later that day.

    You unpack in a room kitted with an AI-powered smart bed, blackout shades, blue light-blocking glasses and weighted blankets.

    Holidays are traditionally for activities or sightseeing – eating Parisian pastry under the Eiffel tower, ice skating at New York City’s Rockefeller Centre, lying by the pool in Bali or sipping limoncello in Sicily. But “sleep tourism” offers vacations for the sole purpose of getting good sleep.

    The emerging trend extends out of the global wellness tourism industry – reportedly worth more than US$800 billion globally (A$1.2 trillion) and expected to boom.

    Luxurious sleep retreats and sleep suites at hotels are popping up all over the world for tourists to get some much-needed rest, relaxation and recovery. But do you really need to leave home for some shuteye?

    Not getting enough

    The rise of sleep tourism may be a sign of just how chronically sleep deprived we all are.

    In Australia more than one-third of adults are not achieving the recommended 7–9 hours of sleep per night, and the estimated cost of this inadequate sleep is A$45 billion each year.

    Inadequate sleep is linked to long-term health problems including poor mental health, heart disease, metabolic disease and deaths from any cause.

    Can a fancy hotel give you a better sleep?

    Many of the sleep services available in the sleep tourism industry aim to optimise the bedroom for sleep. This is a core component of sleep hygiene – a series of healthy sleep practices that facilitate good sleep including sleeping in a comfortable bedroom with a good mattress and pillow, sleeping in a quiet environment and relaxing before bed.

    The more people follow sleep hygiene practices, the better their sleep quality and quantity.

    When we are staying in a hotel we are also likely away from any stressors we encounter in everyday life (such as work pressure or caring responsibilities). And we’re away from potential nighttime disruptions to sleep we might experience at home (the construction work next door, restless pets, unsettled children). So regardless of the sleep features hotels offer, it is likely we will experience improved sleep when we are away.

    What the science says about catching up on sleep

    In the short-term, we can catch up on sleep. This can happen, for example, after a short night of sleep when our brain accumulates “sleep pressure”. This term describes how strong the biological drive for sleep is. More sleep pressure makes it easier to sleep the next night and to sleep for longer.

    But while a longer sleep the next night can relieve the sleep pressure, it does not reverse the effects of the short sleep on our brain and body. Every night’s sleep is important for our body to recover and for our brain to process the events of that day. Spending a holiday “catching up” on sleep could help you feel more rested, but it is not a substitute for prioritising regular healthy sleep at home.

    All good things, including holidays, must come to an end. Unfortunately the perks of sleep tourism may end too.

    Our bodies do not like variability in the time of day that we sleep. The most common example of this is called “social jet lag”, where weekday sleep (getting up early to get to work or school) is vastly different to weekend sleep (late nights and sleep ins). This can result in a sleepy, grouchy start to the week on Monday. Sleep tourism may be similar, if you do not come back home with the intention to prioritise sleep.

    So we should be mindful that as well as sleeping well on holiday, it is important to optimise conditions at home to get consistent, adequate sleep every night.

    5 tips for having a sleep holiday at home

    An AI-powered mattress and a sleep butler at home might be the dream. But these features are not the only way we can optimise our sleep environment and give ourselves the best chance to get a good night’s sleep. Here are five ideas to start the night right:

    1. avoid bright artificial light in the evening (such as bright overhead lights, phones, laptops)

    2. make your bed as comfortable as possible with fresh pillows and a supportive mattress

    3. use black-out window coverings and maintain a cool room temperature for the ideal sleeping environment

    4. establish an evening wind-down routine, such as a warm shower and reading a book before bed or even a “sleepy girl mocktail

    5. use consistency as the key to a good sleep routine. Aim for a similar bedtime and wake time – even on weekends.

  • Escape From The Clutches Of Shame

    We’ve written before about managing various emotions, including “negative” ones. We put that in “scare quotes” because they also all have positive aspects, that are just generally overshadowed by the fact that the emotions themselves are not pleasant. But for example…

    We evolved our emotions, including the “negative” ones, for our own benefit as a species:

    • Stress keeps us safe by making sure we take important situations seriously
    • Anger keeps us safe by protecting us from threats
    • Disgust keeps us safe by helping us to avoid things that might cause disease
    • Anxiety keeps us safe by ensuring we don’t get complacent
    • Guilt keeps us safe by ensuring we can function as a community
    • Sadness keeps us safe by ensuring we value things that are important to us, and learn to become averse to losing them
    • …and so on

    You can read more about how to turn these off (or rather, at least pause them) when they’re misfiring and/or just plain not convenient, here:

    The Off-Button For Your Brain

    While it’s generally considered good to process feelings instead of putting them aside, the fact is that sometimes we have to hold it together while we do something, such that we can later have an emotional breakdown at a convenient time and place, instead of the supermarket or bank or office or airport or while entertaining houseguests or… etc.

    Today, though, we’re not putting things aside, for the most part (though we will get to that too).

    We’ll be dealing with shame, which is closely linked to the guilt we mentioned in that list there.

    See also: Reconsidering the Differences Between Shame and Guilt

    Shame’s purpose

    Shame’s purpose is to help us (as a community) avoid anti-social behavior for which we might be shamed, and thus exiled from the in-group. It helps us all function better together, which is how we thrive as a species.

    Shame, therefore, is often assumed to be something we can (and possibly should) use to ensure that we (ourselves and/or others) “do the right thing”.

    But there’s a catch…

    Shame only works negatively

    You may be thinking “well duh, it’s a negative emotion”, but this isn’t about negativity in the subjective sense, but rather, positive vs negative motivation:

    • Positive motivation: motivation that encourages us to do a given thing
    • Negative motivation: motivation that encourages us to specifically not do a given thing

    Shame is only useful as a negative motivation, i.e., encouraging us to specifically not do a given thing.

    Examples:

    • You cannot (in any way that sticks, at least) shame somebody into doing more housework.
    • You can, however, shame somebody out of drinking and driving.

    This distinction matters a lot when it comes to how we are with our children, or with our employees (or those placed under us in a management structure), or with people who otherwise look to us as leaders.

    It also matters when it comes to how we are with ourselves.

    Here’s a paper about this, by the way, with assorted real-world examples:

    The negative side of motivation: the role of shame

    From those examples, we can see that attempts to shame someone (including oneself) into doing something positive will generally not only fail, they will actively backfire, and people (including oneself) will often perform worse than pre-shaming.

    Looking inwards: healthy vs unhealthy shame

    Alcoholics Anonymous and similar programs use a degree of pro-social shame to help members abstain from the the act being shamed.

    Rather than the unhelpful shame of exiling a person from a group for doing a shameful thing, however, they take an approach of laying out the shame for all to see, feeling the worst of it and moving past it, which many report as being quite freeing emotionally while still [negatively] motivational to not use the substance in question in the future (and similar for activity-based addictions/compulsions, such as gambling, for example).

    As such, if you are trying to avoid doing a thing, shame can be a useful motivator. So by all means, if it’s appropriate to your goals, tell your friends/family about how you are now quitting this or that (be it an addiction, or just something generally unhealthy that you’d like to strike off your regular consumption/activity list).

    You will still be tempted! But the knowledge of the shame you would feel as a result will help keep you from straying into that temptation.

    If you are trying to do a thing, however, (even something thought of in a negative frame, such as “lose weight”), then shame is not helpful and you will do best to set it aside.

    You can shame yourself out of drinking sodas (if that’s your plan), but you can’t shame yourself into eating healthy meals. And even if your plan is just shaming yourself out of eating unhealthy food… Without a clear active positive replacement to focus on instead, all you’ll do there is give yourself an eating disorder. You’ll eat nothing when people are looking, and then either a) also eat next to nothing in private or else b) binge in secret, and feel terrible about yourself, neither of which are any good for you whatsoever.

    Similarly, you can shame yourself out of bed, but you can’t shame yourself into the gym:

    Is there positive in the negative? Understanding the role of guilt and shame in physical activity self-regulation

    Let it go

    There are some cases, especially those where shame has a large crossover with guilt, that it serves no purpose whatsoever, and is best processed and then put aside.

    For example, if you did something that you are ashamed of many years ago, and/or feel guilty about something that you did many years ago, but this is not an ongoing thing for you (i.e., it was a one-off bad decision, or a bad habit that have now long since dropped), then feeling shame and/or guilt about that does not benefit you or anyone else.

    As to how to process it and put it aside, if your thing harmed someone else, you could see if there’s a way to try to make amends (even if without confessing ill, such as by acting anonymously to benefit the person/group you harmed).

    And then, forgive yourself. Regardless of whether you feel like you deserve it. Make the useful choice, that better benefits you, and by extension those around you.

    If you are religious, you may find that of help here too. We’re a health science publication not a theological one, but for example: Buddhism preaches compassion including for oneself. Judaism preaches atonement. Christianity, absolution. For Islam, mercy is one of the holiest ideals of the religion, along with forgiveness. So while religion isn’t everyone’s thing, for those for whom it is, it can be an asset in this regard.

    For a more worldly approach:

    To Err Is Human; To Forgive, Healthy (Here’s How To Do It) ← this goes for when the forgiveness in question is for yourself, too—and we do write about that there (and how)!

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We’ve reviewed books about the evils of sugar before, so what makes this one different?

    This one has a focus on helping the reader quit it. It assumes we already know the evils of sugar (though it does cover that too).

    It looks at the mechanisms of sugar addiction (habits-based and physiological), and how to safely and painlessly cut through those to come out the other side, free from sugar.

    The author gives a day-by-day plan, for not only eliminating sugar, but also adding and including things to fill the gap it leaves, keeping us sated, energized, and happy along the way.

    In the category of subjective criticism, it does also assume we want to lose weight, which may not be the case for many readers. But that’s a by-the-by and doesn’t detract from the useful guide to quitting sugar, whatever one’s reasons.

    Bottom line: if you would like to quit sugar but find it hard, this book thinks of everything and walks you by the hand, making it easy.

  • When You “Can’t Complain”

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    A Bone To Pick… Up And Then Put Back Where We Found It

    In today’s Psychology Sunday feature, we’re going to be flipping the narrative on gratitude, by tackling it from the other end.

    We have, by the way, written previously about gratitude, and what mistakes to avoid, in one of our pieces on positive psychology:

    How To Get Your Brain On A More Positive Track (Without Toxic Positivity)

    “Can’t complain”

    Your mission, should you choose to accept it (and come on, who doesn’t like a challenge?) is to go 21 days without complaining (to anyone, including yourself, about anything). If you break your streak, that’s ok, just start again!

    Why?

    Complaining is (unsurprisingly) inversely correlated with happiness, in a self-perpetuating cycle:

    Pet Peeves and Happiness: How Do Happy People Complain?

    And if a stronger motivation is required, there’s a considerable inverse correlation between all-cause happiness and all-cause mortality, even when potential confounding factors (e.g., chronic health conditions, socioeconomic status, etc) are controlled for, and especially as we get older:

    Investing in Happiness: The Gerontological Perspective

    How?

    You may have already formulated some objections by this point, for example:

    • Am I supposed to tell my doctor/therapist “I’m fine thanks; how are you?”
    • Some things are worthy of complaint; should I be silent?

    But both of these issues (communication, and righteousness) have answers:

    On communication:

    There is a difference between complaining, and giving the necessary information in answer to a question—or even volunteering such information.

    For example, when our site went down yesterday, some of you wrote to us to let us know the links weren’t working. There is a substantive difference (semantic, ontological, and teleological) between:

    • The content was great but the links in “you may have missed” did not work.❞ ← a genuine piece of feedback we received (thank you!)
    • Wasted my time, couldn’t read your articles! Unsubscribing, and I hope your socks get wet tomorrow! ← nobody said this; our subscribers are lovely (thank you)
    • Note that the former wasn’t a complaint, it was genuinely helpful feedback, without which we might not have noticed the problem and fixed it.
    • The latter was a complaint, and also (like many complaints) didn’t even address the actual problem usefully.

    What makes it a complaint or not is not the information conveyed, but the tone and intention. So for example:

    “You’ve only done half the job I asked you to!” → “Thank you for doing the first half of this job, could you please do the other half now?”

    Writer’s anecdote: my washing machine needs a part replaced; the part was ordered two weeks ago and I was told it would take a week to arrive. It’s been two weeks, so tomorrow I will not complain, but I will politely ask whether they have any information about the delay, and a new estimated time of arrival. Because you know what? Whatever the delay is, complaining won’t make it arrive last week!

    On righteousness:

    Indeed, some things are very worthy of complaint. But are you able to effect a solution by complaining? If not, then it’s just hot air. And venting isn’t without its own merits (we touched on the benefits of emotional catharsis recently), but that should be a mindful choice when you choose to do that, not a matter of reactivity.

    Complaining is a subset of criticizing, and criticizing can be done without the feeling and intent of complaining. However, it too should definitely be measured and considered, responsive, not reactive. This itself could be the topic for another main feature, but for now, here’s a Psychology Today article that at least explains the distinction in more words than we have room for here:

    React vs Respond: What’s the difference?

    This, by the way, also goes the same for engaging in social and political discourse. It’s easy to get angry and reactive, but it’s good to take a moment to pick your battles, and by all means fight for what you believe in, and/but also do so responsively rather than reactively.

    Not only will your health thank you, but you’re also more likely to “win friends and influence people” and all that!

    What gets measured, gets done

    Find a way of tracking your streak. There are apps for that, like this one, or you could find a low-tech method you prefer.

    Bonus tip: if you do mess up and complain, and you realize as you’re doing it, take a moment to take a breath and correct yourself in the moment.

    Take care!
