Taurine: Research Review
First, what is taurine, beyond being an ingredient in many energy drinks?
It’s an amino acid that many animals, including humans, can synthesize in our bodies. Some other animals—including obligate carnivores such as cats (but not dogs, who are omnivorous by nature) cannot synthesize taurine and must get it from food.
So, as humans are very versatile omnivorous frugivores by nature, we have choices:
- Synthesize it—no need for any conscious action; it’ll just happen
- Eat it—by eating meat, which contains taurine
- Supplement it—by taking supplements, including energy drinks, which generally (but not always) use a bioidentical lab-made taurine. Basically, lab-made taurine is chemically identical to the kind found in meat, it’s just cheaper and doesn’t involve animals as a middleman.
What does it do?
Taurine does a bunch of essential things, including:
- Maintaining hydration/electrolyte balance in cells
- Regulating calcium/magnesium balance in cells
- Forming bile salts, which are needed for digestion
- Supporting the integrity of the central nervous system
- Regulating the immune system and antioxidative processes
Thus, a shortage of taurine can lead to such issues as kidney problems, eye tissue damage (since the eyes are a particularly delicate part of the CNS), and cardiomyopathy.
If you want to read more, here’s an academic literature review:
Taurine: A “very essential” amino acid
On the topic of eye health, a 2014 study found that taurine is the most plentiful amino acid in the eye, and helps protect against retinal degeneration, in which they say:
❝We here review the evidence for a role of taurine in retinal ganglion cell survival and studies suggesting that this compound may be involved in the pathophysiology of glaucoma or diabetic retinopathy. Along with other antioxidant molecules, taurine should therefore be seriously reconsidered as a potential treatment for such retinal diseases❞

Taurine for muscles… In more than sports!
We’d be remiss not to mention that taurine is enjoyed by athletes to enhance athletic performance; indeed, it’s one of its main selling-points:
See: Taurine in sports and exercise
But! It’s also useful for simply maintaining skeleto-muscular health in general, and especially in the context of age-related decline and chronic disease:
Taurine: the appeal of a safe amino acid for skeletal muscle disorders
On the topic of safety… How safe is it?
There’s an interesting answer to that question. Within safe dose ranges (we’ll get to that), taurine is not only relatively safe, but also, studies that looked to explore its risks found new benefits in the process. Specifically of interest to us were that it appears to promote better long-term memory, especially as we get older (as taurine levels in the brain decline with age):
Taurine, Caffeine, and Energy Drinks: Reviewing the Risks to the Adolescent Brain
^Notwithstanding the title, we assure you, the research got there; they said:
❝Interestingly, the levels of taurine in the brain decreased significantly with age, which led to numerous studies investigating the potential neuroprotective effects of supplemental taurine in several different experimental models❞
What experimental models were those? These ones:
- Taurine protects cerebellar neurons of the external granular layer
- Effects of taurine on alterations of neurobehavior and neurodevelopment key proteins expression
- Neuroprotective role of taurine in developing offspring affected by maternal alcohol consumption
…which were all animal studies, however.
The same systematic review also noted that not only was more research needed on humans, but also, existing studies have had a strong bias to male physiology (in both human and assorted other animal studies), so more diverse study is needed too.
What are the safe dose ranges?
Before we get to toxicity, let’s look at some therapeutic doses. In particular, some studies that found that 500mg 3x daily, i.e. 1.5g total daily, had benefits for heart health:
- Taurine and atherosclerosis
- The Anti-Inflammatory Effect of Taurine on Cardiovascular Disease
- Taurine supplementation has anti-atherogenic and anti-inflammatory effects before and after incremental exercise in heart failure
- Taurine Supplementation Lowers Blood Pressure and Improves Vascular Function in Prehypertension
- Taurine improves the vascular tone through the inhibition of TRPC3 function in the vasculature
Bottom line on safety: 3g/day has been found to be safe:

Gut-Healthy Spaghetti Chermoula
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.
Chermoula is a Maghreb relish/marinade (it’s used for both purposes); it’s a little like chimichurri but with distinctly N. African flavors. The gut-healthiness starts there (it’s easy to forget that olives—unless fresh—are a fermented food full of probiotic Lactobacillus sp. and thus great for the gut even beyond their fiber content), and continues in the feta, the vegetables, and the wholewheat nature of the pasta. The dish can be enjoyed at any time, but it’s perfect for warm summer evenings—perhaps dining outside, if you’ve place for that.
You will need
- 9oz wholewheat spaghetti (plus low-sodium salt for its water)
- 10oz broccoli, cut into small florets
- 3oz cilantro (unless you have the soap gene)
- 3oz parsley (whether or not you included the cilantro)
- 3oz green olives, pitted, rinsed
- 1 lemon, pickled, rinsed
- 1 bulb garlic
- 3 tbsp pistachios, shelled
- 2 tbsp mixed seeds
- 1 tsp cumin
- 1 tsp chili flakes
- ½ cup extra virgin olive oil
- For the garnish: 3oz feta (or plant-based equivalent), crumbled, 3oz sun-dried tomatoes, diced, 1 tsp cracked black pepper
Note: why are we rinsing the things? It’s because while picked foods are great for the gut, the sodium can add up, so there’s no need to bring extra brine with them too. By doing it this way, there’ll be just the right amount for flavor, without overdoing it.
Method
(we suggest you read everything at least once before doing anything)
1) Cook the spaghetti as you normally would, but when it’s a minute or two from being done, add the broccoli in with it. When it’s done, drain and rinse thoroughly to get rid of excess starch and salt, and also because cooling it even temporarily (as in this case) lowers its glycemic index.
2) Put the rest of the ingredients into a food processor (except the olive oil and the garnish), and blitz thoroughly until no large coarse bits remain. When that’s done, add the olive oil, and pulse it a few times to combine. We didn’t add the olive oil previously, because blending it so thoroughly in that state would have aerated it in a way we don’t want.
3) Put ⅔ of the chermoula you just made into the pan you used for cooking the spaghetti, and set it over a medium heat. When it starts bubbling, return the spaghetti and broccoli to the pan, mixing gently but thoroughly. If the pasta threatens to stick, you can add a little more chermoula, but go easy on it. Any leftover chermoula that you didn’t use today, can be kept in the fridge and used later as a pesto.
4) Serve! Add the garnish as you do.
Enjoy!

Who Screens The Sunscreens?
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 Screen The Sunscreens!
Yesterday, we asked you what your sunscreen policy was, and got a spread of answers. Apparently this one was quite polarizing!
One subscriber who voted for “Sunscreen is essential to protect us against skin aging and cancer” wrote:
❝My mom died of complications from melanoma, so we are vigilant about sun and sunscreen. We are a family of campers and hikers and gardeners—outdoors in all seasons—and we never burn❞
Our condolences with regard to your mom! Life is so precious, and when something like that happens, it tends to stick with us. We’re glad you and your family are taking care of yourselves.
Of the subscribers who voted for “I put some on if I think I might otherwise get sunburned”, about half wrote to express uncertainties:
- uncertainty about how safe it is, and
- uncertainty about how helpful it is
…so we’re going to tackle those questions in a moment. But what of those who voted for “Sunscreen is full of harmful chemicals that can cause cancer”?
Of those, only one wrote a message, which was to say one has to be very careful of what is in the formula.
Let’s take a look, then…
Sunscreen is full of harmful chemicals that can cause cancer: True or False?
False—according to current best science. Research is ongoing!
There are four main chemicals (found in most sunscreens) that people tend to worry about:
- Abobenzone
- Oxybenzone
- Octocrylene
- Ecamsule
Now, these two sound like four brands of rocket fuel, but then, dihydrogen monoxide (DHMO), which is also found in most sunscreens, sounds like a deadly toxin too. That’s water, by the way.
But what of these four chemicals? Well, as we say, research is ongoing, but we found a study that measured all four, to see how much got into the blood, and what adverse effects, if any, this caused.
We’ll skip to their conclusion:
❝In this preliminary study involving healthy volunteers, application of 4 commercially available sunscreens under maximal use conditions resulted in plasma concentrations that exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens. The systemic absorption of sunscreen ingredients supports the need for further studies to determine the clinical significance of these findings. These results do not indicate that individuals should refrain from the use of sunscreen.❞
Now, “exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens” sounds alarming, so why did they close with the words “These results do not indicate that individuals should refrain from the use of sunscreen”?
Let’s skip back up to a line from the results:
❝The most common adverse event was rash, which developed in 1 participant with each sunscreen.❞
This was most probably due to the oxybenzone, which can cause allergic skin reactions in some people.
Let us take a moment to remember the most common adverse event that occurs from not wearing sunscreen: sunburn!
You can read the full study here:
None of those ingredients have been found to be carcinogenic, even at the maximal blood plasma concentrations studied, from applications 4x/day to 75% of the body.
UVA rays, on the other hand, are absolutely very much known to cause cancer, and the effect is cumulative.
Sunscreen is essential to protect us against skin aging and cancer: True or False?
True, unequivocally, unless we live indoors and/or otherwise never go about under sunlight.
“But our ancestors—” lived under the same sun we do, and either used sunscreen or got advanced skin aging and cancer.
Sunscreen of times past ranged from mud to mineral lotions, but it’s pretty much always existed. Even non-human animals that have skin and don’t have fur or feathers, tend to take mud-baths in sunny parts of the world.
If you’d like to avoid oxybenzone and other chemicals, though, you might have your reasons. Maybe you’re allergic, or maybe you read that it’s a potential endocrine disruptor with estrogen-like and anti-androgenic properties that you don’t want.
There are other options, to include physical blockers containing zinc and titanium dioxide, which are generally recognized as safe and effective ingredients.
If you’re interested, you can even make your own sunscreen that blocks both UVA and UVB rays (UVA is what causes skin cancer; UVB is “milder” and is what causes sunburn):

Sizing Aside: Are You Wearing The Right Bra For Your Breast Shape?
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.
It’s well-known that most women wear incorrectly-fitting bras. Even with careful measurements, buying “off-the-rack” can be a challenge, because the sizing system only takes two measurements, when there are actually many more things to consider. Today’s video demystifies a lot of what else is going on!
For example…
Some of the different breast shapes/arrangements to consider:
- Wide-set breasts: likely to find there’s a bit of a gap between your breasts and the inside (nearest to your sternum) parts of the cups—while spilling out a little at the outside edges. The solution? Bras that offer side-support, to keep things pointing more forwards. Central-closing bras can also help gather things together, and a balconette bra can redistribute things more evenly. Any of these options will be a lot more comfortable.
- Small breasts: bralettes are your friend, keeping things comfortable while not wearing more bra than necessary to do the job (of course going braless is also an option, but we’re talking bra-fitting here, not bra-flinging-off never to be seen again)
- Deflated breasts: often the case for someone who used to have larger breasts, but they lost size for hormonal reasons rather than for weight loss reasons. This often occurs a little while after childbirth, and also happens a lot in menopause. The bra recommendation for this? A push-up plunge bra with ¾ coverage not only provides cleavage if that’s wanted, but also, will keep things much more snug and thus more evenly-distributed. If ever you’ve found yourself needing to adjust yourself every now and gain while out, this will fix that and keep you comfortable for much longer.

The Borderline Personality Disorder Workbook – by Dr. Daniel Fox
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.
Personality disorders in general get a bad rep. In part, because their names and descriptions often focus on how the disorders affect other people, rather than how they affect the actual sufferer:
- “This disorder gives you cripplingly low self-esteem; we call it Evil Not-Quite-Human Disorder”
- “This disorder makes you feel unloveable; we call it Abusive Bitch Disorder”
- …etc
Putting aside the labels and stigma, it turns out that humans sometimes benefit from help. In the case of BPD, characterized by such things as difficult moods and self-sabotage, the advice in this book can help anyone struggling with those (and related) issues.
The style of the book is both textbook, and course. It’s useful to proceed through it methodically, and doing the exercises is good too. We recommend getting the print edition, not the Kindle edition, so that you can check off boxes, write in it (pencil, if you like!), etc.
Bottom line: if you or a loved one suffers from BPD symptoms (whether or not you/they would meet criteria for diagnosis), this book can help a lot.

Reaching for better health
In this short video, Liv describes and shows three exercises:
Exercise 1: Thoracic Pullover (Dumbbell Pullover)
Purpose: Improves overhead reach and shoulder mobility.
Equipment: light weight, yoga block, or foam roller.
Steps:- Lie on the floor with the foam roller/block beneath the upper back.
- Hold the weight in both hands, arms extended upward.
- Inhale deeply and reach the weight toward the ceiling.
- Exhale and arc your spine over the block, moving the weight backward.
- Keep core tension to maintain a neutral lower back position.
- Perform 10 repetitions.
Exercise 2: Rotational Mobility Stretch
Purpose: enhances torso rotation, core strength, and hip mobility.
Equipment: none (or a mat)
Steps:- Lie on your side with knees stacked at 90° and arms extended in front.
- Hold a weight in the top hand.
- Inhale and lift the top arm toward the ceiling, extending the shoulder blade.
- Exhale and twist your torso, allowing the arm to move toward the floor.
- Modify by extending the bottom leg for a deeper twist if needed.
- Perform 6 reps per side, switching legs and repeating on the other side.
Exercise 3: Doorway/Pole Side Stretch
Purpose: targets multiple areas for a deep, satisfying stretch.
Equipment: door frame, pole, or wall.
Steps:- Stand at arm’s length from the wall or frame.
- Cross the outer leg (furthest from the wall) behind the inner leg.
- Place the closest hand on the wall and reach the other arm overhead.
- Grip the wall or frame with the top hand, pressing away with the bottom hand.
- Lean into a banana-shaped curve and rotate your chest upward for a deeper stretch.

Shoulders Range – by Elia Bartolini
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.
Shoulder flexibility and mobility can be a big deal, especially when it starts to decline—more so than other kinds of flexibility. Most seniors can get through the day without doing the splits against a wall, for example, but shoulder tightness can be more of a problem if you can’t easily get into or out of your clothes.
If you think it couldn’t happen to you: the great Jane Fonda has a now-famous photoset of her looking glamorous in a dress at a red carpet event, and then looking frazzled making breakfast in the same dress in her kitchen the next morning, because, as she wrote, “I couldn’t get my dress unzipped so I slept in it”.
Now, “to avoid ending up like Jane Fonda” is not a series of words that usually precedes advice, but in this case: this book delves into the science of one of the most quirky joints of the human body, and how to leverage this to maximize shoulder mobility, while maintaining adequate strength (because flexibility without strength is just asking for a dislocation) without doing anything that would actually bulk up our shoulders, because it’s just about progressing through passive, active, and tensed stretching, static, dynamic, and loaded stretching, as well as PNF stretching and antagonist stretching.
If that seems like a lot of stretching, don’t worry; the author presents a series of workouts that will take us through these stretches in a very small amount of time each day.
The style is instructional like a textbook, with clear diagrams where appropriate, and lots of callout boxes, bullet points, emboldening for key points, etc. It all makes for every easy learning.
Bottom line: if you’d like to improve and maintain your shoulder mobility, this is an excellent book for that.
