Tribulus Terrestris For Testosterone?

(Clinical) Trials and Tribul-ations

In the category of supplements that have enjoyed use as aphrodisiacs, Tribulus terrestris (also called caltrop, goat’s head, gokshura, or puncture vine) has a long history, having seen wide use in both Traditional Chinese Medicine and in Ayurveda.

It’s been used for other purposes too, and has been considered a “general wellness” plant.

So, what does the science say?

Good news: very conclusive evidence!

Bad news: the conclusion is not favorable…

Scientists are known for their careful use of clinical language, and it’s very rare for a study/review to claim something as proven (scientists leave journalists to do that part), and in this case, when it comes to Tribulus’s usefulness as a testosterone-enhancing libido-boosting supplement…

❝analysis of empirical evidence from a comprehensive review of available literature proved this hypothesis wrong❞

~ Drs. Neychev & Mitev

Strong words! You can read it in full here; they do make some concessions along the way (e.g. mentioning unclear or contradictory findings, suggesting that it may have some effect, but by an as-yet unknown mechanism if it does—although some potential effect on nitric oxide levels has been hypothesized, which is reasonable if so, as NO does feature in arousal-signalling), but the general conclusion is “no, this doesn’t have androgen-enhancing properties”:

From sport, into general wellness?

Finally, a study that finds it may be useful for something!

❝Overall, participants supplemented with TT displayed significant improvements in lipid profile. Inflammatory and hematological biomarkers showed moderate beneficial effects with no significant changes on renal biomarkers. No positive effects were observed on the immune system response. Additionally, no TT-induced toxicity was reported.

In conclusion, there was no clear evidence of the beneficial effects of TT supplementation on muscle damage markers and hormonal behavior.❞

~ Dr. Fernández-Lázaro et al.

About those lipids…

Animal studies have shown that it may not only improve lipid profiles, but also may partially repair the endothelial dysfunction resulting from hyperlipidemia:

  • How To Avoid Carer Burnout (Without Dropping Care)

    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.

    How To Avoid Carer Burnout

    Sometimes in life we find ourselves in a caregiving role.

    Maybe we chose it. For example, by becoming a professional carer, or even just by being a parent.

    Oftentimes we didn’t. Sometimes because our own parents now need care from us, or because a partner becomes disabled.

    Philosophical note: an argument could be made for that latter also having been a pre-emptive choice; we probably at some point said words to the effect of “in sickness and in health”, hopefully with free will, and hopefully meant it. And of course, sometimes we enter into a relationship with someone who is already disabled.

    But, we are not a philosophy publication, and will henceforth keep to the practicalities.

    First: are you the right person?

    Sometimes, a caregiving role might fall upon you unasked-for, and it’s worth considering whether you are really up for it. Are you in a position to be that caregiver? Do you want to be that caregiver?

    It may be that you do, and would actively fight off anyone or anything that tried to stop you. If so, great, now you only need to make sure that you are actually in a position to provide the care in question.

    It may be that you do want to, but your circumstances don’t allow you to do as good a job of it as you’d like, or it means you have to drop other responsibilities, or you need extra help. We’ll cover these things later.

    It may be that you don’t want to, but you feel obliged, or “have to”. If that’s the case, it will be better for everyone if you acknowledge that, and find someone else to do it. Nobody wants to feel a burden, and nobody wants someone providing care to be resentful of that. The result of such is two people being miserable; that’s not good for anyone. Better to give the job to someone who actually wants to (a professional, if necessary).

    So, be honest (first with yourself, then with whoever may be necessary) about your own preferences and situation, and take steps to ensure you’re only in a caregiving role that you have the means and the will to provide.

    Second: are you out of your depth?

    Some people have had a life that’s prepared them for being a carer. Maybe they worked in the caring profession, maybe they have always been the family caregiver for one reason or another.

    Yet, even if that describes you… Sometimes someone’s care needs may be beyond your abilities. After all, not all care needs are equal, and someone’s condition can (and more often than not, will) deteriorate.

    So, learn. Learn about the person’s condition(s), medications, medical equipment, etc. If you can, take courses and such. The more you invest in your own development in this regard, the more easily you will handle the care, and the less it will take out of you.

    And, don’t be afraid to ask for help. Maybe the person knows their condition better than you, and certainly there’s a good chance they know their care needs best. And certainly, there are always professionals that can be contacted to ask for advice.

    Sometimes, a team effort may be required, and there’s no shame in that either. Whether it means enlisting help from family/friends or professionals, sometimes “many hands make light work”.

    A very good resource-hub for help, advice, & community

    Third: put your own oxygen mask on first

    Like the advice to put on one’s own oxygen mask first before helping others (in the event of a cabin depressurization in an airplane), the rationale is the same here. You can’t help others if you are running on empty yourself.

    As a carer, sometimes you may have to put someone else’s needs above yours, both in general and in the moment. But, you do have needs too, and cannot neglect them (for long).

    One sleepless night looking after someone else is… a small sacrifice for a loved one, perhaps. But several in a row starts to become unsustainable.

    Sometimes it will be necessary to do the best you can, and accept that you cannot do everything all the time.

    There’s a saying amongst engineers that applies here too: “if you don’t schedule time for maintenance, your equipment will schedule it for you”.

    In other words: if you don’t give your body rest, your body will break down and oblige you to rest. Please be aware this goes for mental effort too; your brain is just another organ.

    So, plan ahead, schedule breaks, find someone to take over, set up your cared-for-person with the resources to care for themself as well as possible (do this anyway, of course—independence is generally good so far as it’s possible), and make the time/effort to get you what you need for you. Sleep, distraction, a change of scenery, whatever it may be.

    Lastly: what if it’s you?

    If you’re reading this and you’re the person who has the higher care needs, then firstly:all strength to you. You have the hardest job here; let’s not forget that.

    About that independence: well-intentioned people may forget that, so don’t be afraid to remind them when “I would prefer to do that myself”. Maintaining independence is generally good for the health, even if sometimes it is more work for all concerned than someone else doing it for you. The goal, after all, is your wellbeing, so this shouldn’t be cast aside lightly.

    On the flipside: you don’t have to be strong all the time; nobody should.

    Being disabled can also be quite isolating (this is probably not a revelation to you), so if you can find community with other people with the same or similar condition(s), even if it’s just online, that can go a very, very long way to making things easier. Both practically, in terms of sharing tips, and psychologically, in terms of just not feeling alone.

  • Algorithms to Live By – by Brian Christian and Tom Griffiths

    As humans, we subconsciously use heuristics a lot to make many complex decisions based on “fuzzy logic”. For example:

    Do we buy the cheap shoes that may last us a season, or the much more expensive ones that will last us for years? We’ll—without necessarily giving it much conscious thought—quickly weigh up:

    • How much do we like each prospective pair of shoes?
    • What else might we need to spend money on now/soon?
    • How much money do we have right now?
    • How much money do we expect to have in the future?
    • Considering our lifestyle, how important is it to have good quality shoes?

    How well we perform this rapid calculation may vary wildly, depending on many factors ranging from the quality of the advertising to how long ago we last ate.

    And if we make the wrong decision, later we may have buyer’s (or non-buyer’s!) remorse. So, how can we do better?

    Authors Brain Christian and Tom Griffiths have a manual for us!

    This book covers many “kinds” of decision we often have to make in life, and how to optimize those decisions with the power of mathematics and computer science.

    The problems (and solutions) run the gamut of…

    • Optimal stopping (when to say “alright, that’s good enough”)
    • Overcoming cognitive biases
    • Scheduling quandaries
    • Bayes’ Theorem
    • Game Theory
    • And when it’s more efficient to just leave things to chance!

    …and many more (12 main areas of decision-making are covered).

    For all it draws heavily from mathematics and computer science, the writing style is very easy-reading. It’s a “curl up in the armchair and read for pleasure” book, no matter how weighty and practical its content.

    Bottom line: if you improve your ability to make the right decisions even marginally, this book will have been worth your while in the long run!

  • This Naked Mind – by Annie Grace

    We’ve all read about the many, many, dangers of drinking. We’ve also probably all read about how to make the change to not drinking. Put things out of sight, tell your friends, have this rule, have this excuse (for not drinking) ready to give to people who challenge you, consider a support group, and so on.

    What Annie Grace offers in this #1 bestseller is different:

    A blend of mostly psychology and sociology, to examine the “liminal thinking” stages that funnel us to drink in the first place… and where that leads, and how to clamber back out of the pitcher plant we weren’t necessarily aware we were sliding into.

    While she kicks off citing Jung, from a psychological perspective more of this book is CBTish, as it pertains a lot to examining the process of:

    • belief—held and defended, based on the…
    • conclusion—drawn, often irrationally, from the…
    • experience—that we had upon acting on an…
    • observation—often mistaking an illusion for the underlying…
    • reality

    …and how we can and often do go wrong at each step, and how little of the previous steps we can perceive at any given time.

    What does this mean for managing/treating alcoholism or a tendency towards alchoholism?

    It means interrupting those processes in a careful, surgically precise fashion, so that suddenly… The thing has no more power over us.

    Whether you or a loved one struggle with a tendency to addiction (any addiction, actually, the advice goes the same), or are just curious about the wider factors at hand in the epidemiology of addiction, this book is for you.

    “Eat beans and greens”, we say, “but how”, you ask. Here’s how! Tasty, filling, and fulfilling, this dish is full of protein, fiber, vitamins, minerals, and assorted powerful phytochemicals.

    You will need

    • 2½ cups low-sodium vegetable stock
    • 2 cans cannellini beans, drained and rinsed
    • 1 cup kale, stems removed and roughly chopped
    • 4 dried shiitake mushrooms
    • 2 shallots, sliced
    • ½ bulb garlic, crushed
    • 1 tbsp white miso paste
    • 1 tbsp nutritional yeast
    • 1 tsp rosemary leaves
    • 1 tsp thyme leaves
    • 1 tsp black pepper, coarse ground
    • ½ tsp red chili flakes
    • Juice of ½ lemon
    • Extra virgin olive oil
    • Optional: your favorite crusty bread, perhaps using our Delicious Quinoa Avocado Bread recipe

    Method

    (we suggest you read everything at least once before doing anything)

    1) Heat some oil in a skillet and fry the shallots for 2–3 minutes.

    2) Add the nutritional yeast, garlic, herbs, and spices, and stir for another 1 minute.

    3) Add the beans, vegetable stock, and mushrooms. Simmer for 10 minutes.

    4) Add the miso paste, stirring well to dissolve and distribute evenly.

    5) Add the kale until it begins to wilt, and remove the pot from the heat.

    6) Add the lemon juice and stir.

    7) Serve; we recommend enjoying it with crusty wholegrain bread.

    Enjoy!

    Beyond “Make Your Bed”—life lessons from experience

    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.

    Beyond “Make Your Bed”—life lessons from experience

    This is Admiral William H. McRaven, a former United States Navy four-star admiral who served as the ninth commander of the United States Special Operations Command.

    So, for those of us whose day-to-day lives don’t involve coordinating military operations, what does he have to offer?

    Quick note: 10almonds’ mission statement is “to make health and productivity crazy simple”.

    We tend to focus on the health side of this, and in the category of productivity, it’s often what most benefits our mental health.

    We’re writing less for career-driven technopreneurs in the 25–35 age bracket and more for people with a more holistic view of productivity and “a good life well-lived”.

    So today’s main feature is more in that vein!

    Start each day with an accomplishment

    McRaven famously gave a speech (and wrote a book) that began with the advice, “make your bed”. The idea here doesn’t have to be literal (if you’ll pardon the pun). Indeed, if you’re partnered, then depending on schedules and habits, it could be you can’t (sensibly) make your bed first thing because your partner is still in it. But! What you can do is start the day with an accomplishment—however small. A short exercise routine is a great example!

    Success in life requires teamwork

    We’re none of us an island (except in the bathtub). The point is… Nobody can do everything alone. Self-sufficiency is an illusion. You can make your own coffee, but could you have made the coffee machine, or even the cup? How about, grown the coffee? Transported it? So don’t be afraid to reach out for (and acknowledge!) help from others. Teamwork really does make the dream work.

    It’s what’s inside that counts

    It’s a common trap to fall into, getting caught up the outside appearance of success, rather than what actually matters the most. We need to remember this when it comes to our own choices, as well as assessing what others might bring to the table!

    A setback is only permanent if you let it be

    No, a positive attitude won’t reverse a lifelong degenerative illness, for example. But what we can do, is take life as comes, and press on with the reality, rather than getting caught up in the “should be”.

    Use failure to your advantage

    Learn. That’s all. Learn, and improve.

    Be daring in life

    To borrow from another military force, the SAS has the motto “Who dares, wins”. Caution has it place, but if we’ve made reasonable preparations*, sometimes being bold is the best (or only!) way forward.

    *Meanwhile the Parachute Regiment, from which come 80% of all SAS soldiers, has the motto “Utrinque paratus”, “prepared on all sides”.

    Keep courage close

    This is about not backing down when we know what’s right and we know what we need to do. Life can be scary! But if we don’t overcome our fears, they can become self-realizing.

    Writer’s note: a good example of this is an advice I sometimes gave during my much more exciting (military) life of some decades ago, and it pertains to getting into a knife-fight (top advice for civilians: don’t).

    But, if you’re in one, you need to not be afraid of getting cut.

    Because if you’re not afraid of getting cut, you will probably get cut.

    But if you are afraid of getting cut, you will definitely get cut.

    Hopefully your life doesn’t involve knives outside of the kitchen (mine doesn’t, these days, and I like it), but the lesson applies to other things too.

    Sometimes the only way out is through.

    Be your best at your worst

    Sometimes life is really, really hard. But if we allow those moments to drive us forwards, they’re also a place we can find more strength than we ever knew we had.

    Keep on swimming

    It’s said that the majority in life is about showing up—and often it is. But you have to keep showing up, day after day. So make what you’re doing sustainable for you, and keep on keeping on.

  • Cashew Nuts vs Macadamia Nuts – Which is Healthier?

    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.

    Our Verdict

    When comparing cashews to macadamias, we picked the cashews.

    Why?

    In terms of macros, cashews have more than 2x the protein, while macadamias have nearly 2x the fat. The fats are mostly monounsaturated, so it’s still healthy in moderation, but still, we’re going to prize the protein over it and call this category a nominal win for cashews.

    When it comes to vitamins, things are fairly even; cashews have more of vitamins B5, B6, B9, and E, while macadamias have more of vitamins B1, B2, B3, and C.

    In the category of minerals, cashews take the clear lead; cashews have more copper, iron, magnesium, phosphorus, potassium, selenium, and zinc, while macadamias have more calcium and manganese.

    In short, enjoy both (as macadamias have their benefits too), but cashews win in total nutrient density.
