Our Verdict
When comparing magnesium glycinate to magnesium citrate, we picked the citrate.
Why?
Both are fine sources of magnesium, a nutrient in which it’s very common to be deficient—a lot of people don’t eat many leafy greens, beans, nuts, and so forth that contain it.
A quick word on a third contender we didn’t include here: magnesium oxide is probably the most widely-sold magnesium supplement because it’s cheapest to make. It also has woeful bioavailability, to the point that there seems to be negligible benefit to taking it. So we don’t recommend that.
Magnesium glycinate and magnesium citrate are both absorbed well, but magnesium citrate is the most well-absorbed form of magnesium supplement.
In terms of the relative merits of the glycine or the citric acid (the “other part” of magnesium glycinate and magnesium citrate, respectively), both are also great nutrients, but the amount delivered with the magnesium is quite small in each case, and so there’s nothing here to swing it one way or the other.
For this reason, we went with the magnesium citrate, as the most readily bioavailable!

Red Light, Go!

Casting Yourself In A Healthier Light
In Tuesday’s newsletter, we asked you for your opinion of red light therapy (henceforth: RLT), and got the above-depicted, below-described, set of responses:
- About 51% said “I have no idea whether light therapy works or not”
- About 24% said “Red light therapy is a valuable skin rejuvenation therapy”
- About 23% said “I have not previously heard of red light therapy”
- One (1) person said: “Red light therapy is a scam to sell shiny gadgets”
A number of subscribers wrote with personal anecdotes of using red light therapy to beneficial effect, for example:
❝My husband used red light therapy after surgery on his hand. It did seem to speed healing of the incision and there is very minimal scarring. I would like to know if the red light really helped or if he was just lucky❞
~ 10almonds subscriber
And one wrote to report having observed mixed results amongst friends, per:
❝Some people it works, others I’ve seen it breaks them out❞
~ 10almonds subscriber
So, what does the science say?
RLT rejuvenates skin, insofar as it reduces wrinkles and fine lines: True or False?
True! This one’s pretty clear-cut, so we’ll just give one example study of many, which found:
❝The treated subjects experienced significantly improved skin complexion and skin feeling, profilometrically assessed skin roughness, and ultrasonographically measured collagen density.
The blinded clinical evaluation of photographs confirmed significant improvement in the intervention groups compared with the control❞
~ Dr. Alexander Wunsch & Dr. Karsten Matuschka
RLT helps speed up healing of wounds: True or False?
True! There is less science for this than the above claim, but the studies that have been done are quite compelling, for example this NASA technology study found that…
❝LED produced improvement of greater than 40% in musculoskeletal training injuries in Navy SEAL team members, and decreased wound healing time in crew members aboard a U.S. Naval submarine.❞
Read more: Effect of NASA light-emitting diode irradiation on wound healing
RLT’s benefits are only skin-deep: True or False?
False, probably, but we’d love to see more science for this, to be sure.
However, it does look like wavelengths in the near-infrared spectrum reduce the abnormal tau protein and neurofibrillary tangles associated with Alzheimer’s disease, resulting in increased blood flow to the brain, and a decrease in neuroinflammation:

Would you like to try RLT for yourself?
There are some contraindications, for example:
- if you have photosensitivity (for obvious reasons)
- if you have Lupus (mostly because of the above)
- if you have hyperthyroidism (because if you use RLT to your neck as well as face, it may help stimulate thyroid function, which in your case is not what you want)
As ever, please check with your own doctor if you’re not completely sure; we can’t cover all bases here, and cannot speak for your individual circumstances.
For most people though, it’s very safe, and if you’d like to try it, here’s an example product on Amazon, and by all means do read reviews and shop around for the ideal device for you
Take care! 😎

Why do I poo in the morning? A gut expert explains
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.
No, you’re not imagining it. People really are more likely to poo in the morning, shortly after breakfast. Researchers have actually studied this.
But why mornings? What if you tend to poo later in the day? And is it worth training yourself to be a morning pooper?
To understand what makes us poo when we do, we need to consider a range of factors including our body clock, gut muscles and what we have for breakfast.
Here’s what the science says.
So morning poos are real?
In a UK study from the early 1990s, researchers asked nearly 2,000 men and women in Bristol about their bowel habits.
The most common time to poo was in the early morning. The peak time was 7-8am for men and about an hour later for women. The researchers speculated that the earlier time for men was because they woke up earlier for work.
About a decade later, a Chinese study found a similar pattern. Some 77% of the almost 2,500 participants said they did a poo in the morning.
But why the morning?
There are a few reasons. The first involves our circadian rhythm – our 24-hour internal clock that helps regulate bodily processes, such as digestion.
For healthy people, our internal clock means the muscular contractions in our colon follow a distinct rhythm.
There’s minimal activity in the night. The deeper and more restful our sleep, the fewer of these muscle contractions we have. It’s one reason why we don’t tend to poo in our sleep.
But there’s increasing activity during the day. Contractions in our colon are most active in the morning after waking up and after any meal.
One particular type of colon contraction partly controlled by our internal clock are known as “mass movements”. These are powerful contractions that push poo down to the rectum to prepare for the poo to be expelled from the body, but don’t always result in a bowel movement. In healthy people, these contractions occur a few times a day. They are more frequent in the morning than in the evening, and after meals.
Breakfast is also a trigger for us to poo. When we eat and drink our stomach stretches, which triggers the “gastrocolic reflex”. This reflex stimulates the colon to forcefully contract and can lead you to push existing poo in the colon out of the body. We know the gastrocolic reflex is strongest in the morning. So that explains why breakfast can be such a powerful trigger for a bowel motion.
Then there’s our morning coffee. This is a very powerful stimulant of contractions in the sigmoid colon (the last part of the colon before the rectum) and of the rectum itself. This leads to a bowel motion.
How important are morning poos?
Large international surveys show the vast majority of people will poo between three times a day and three times a week.
This still leaves a lot of people who don’t have regular bowel habits, are regular but poo at different frequencies, or who don’t always poo in the morning.
So if you’re healthy, it’s much more important that your bowel habits are comfortable and regular for you. Bowel motions do not have to occur once a day in the morning.
Morning poos are also not a good thing for everyone. Some people with irritable bowel syndrome feel the urgent need to poo in the morning – often several times after getting up, during and after breakfast. This can be quite distressing. It appears this early-morning rush to poo is due to overstimulation of colon contractions in the morning.
Can you train yourself to be regular?
Yes, for example, to help treat constipation using the gastrocolic reflex. Children and elderly people with constipation can use the toilet immediately after eating breakfast to relieve symptoms. And for adults with constipation, drinking coffee regularly can help stimulate the gut, particularly in the morning.
A disturbed circadian rhythm can also lead to irregular bowel motions and people more likely to poo in the evenings. So better sleep habits can not only help people get a better night’s sleep, it can help them get into a more regular bowel routine.
Regular physical activity and avoiding sitting down a lot are also important in stimulating bowel movements, particularly in people with constipation.
We know stress can contribute to irregular bowel habits. So minimising stress and focusing on relaxation can help bowel habits become more regular.
Fibre from fruits and vegetables also helps make bowel motions more regular.
Finally, ensuring adequate hydration helps minimise the chance of developing constipation, and helps make bowel motions more regular.
Monitoring your bowel habits
Most of us consider pooing in the morning to be regular. But there’s a wide variation in normal so don’t be concerned if your poos don’t follow this pattern. It’s more important your poos are comfortable and regular for you.
If there’s a major change in the regularity of your bowel habits that’s concerning you, see your GP. The reason might be as simple as a change in diet or starting a new medication.
But sometimes this can signify an important change in the health of your gut. So your GP may need to arrange further investigations, which could include blood tests or imaging.

6-Minute Core Strength – by Dr. Jonathan Su
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 don’t normally do author biographies here, but in this case it’s worth noting that Dr. Su is a physiotherapist, military rehab expert, and an IAYT yoga therapist. So, these things together certainly do lend weight to his advice.
About the “6-minute” thing: this is in the style of the famous “7-minute workout” and “5 Minutes’ Physical Fitness” etc, and refers to how long each exercise session should take. The baseline is one such session per day, though of course doing more than one set of 6 minutes each time is a bonus if you wish to do so.
The exercises are focused on core strength, but they also include hip and shoulder exercises, since these are after all attached to the core, and hip and shoulder mobility counts for a lot.
A particular strength of the book is in troubleshooting mistakes of the kind that aren’t necessarily visible from photos; in this case, Dr. Su explains what you need to go for in a certain exercise, and how to know if you are doing it correctly. This alone is worth the cost of the book, in this reviewer’s opinion.
Bottom line: if you want core strength and want it simple yet comprehensive, this book can guide you.

Thinner Leaner Stronger – by Michael Matthews
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.
First, the elephant in the training room: this book does assume that you want to be thinner, leaner, and stronger. This is the companion book, written for women, to “Bigger, Stronger, Leaner”, which was written for men. Statistically, these assumptions are reasonable, even if the generalizations are imperfect. Also, this reviewer has a gripe with anything selling “thinner”. Leaner was already sufficient, and “stronger” is the key element here, so “thinner” is just marketing, and marketing something that’s often not unhealthy, to sell a book that’s actually full of good advice for building a healthy body.
In other words: don’t judge a book by the cover, however eyeroll-worthy it may be.
The book is broadly aimed at middle-aged readers, but boasts equal worth for young and old alike. If there’s something Matthews knows how to do well in his writing, it’s hedging his bets.
As for what’s in the book: it’s diet and exercise advice, aimed at long-term implementation (i.e. not a crash course, but a lifestyle change), for maximum body composition change results while not doing anything silly (like many extreme short-term courses do) and not compromising other aspects of one’s health, while also not taking up an inordinate amount of time.
The dietary advice is sensible, broadly consistent with what we’d advise here, and/but if you want to maximise your body composition change results, you’re going to need a pocket calculator (or be better than this writer is at mental arithmetic).
The exercise advice is detailed, and a lot more specific than “lift things”; there are programs of specifically how many sets and reps and so forth, and when to increase the weights and when not to.
A strength of this book is that it explains why all those numbers are what they are, instead of just expecting the reader to take on faith that the best for a given exercise is (for example) 3 sets of 8–10 reps of 70–75% of one’s single-rep max for that exercise. Because without the explanation, those numbers would seem very arbitrary indeed, and that wouldn’t help anyone stick with the program. And so on, for any advice he gives.
The style is… A little flashy for this reader’s taste, a little salesy (and yes he does try to upsell to his personal coaching, but really, anything you need is in the book already), but when it comes down to it, all that gym-boy bravado doesn’t take away from the fact his advice is sound and helpful.
Bottom line: if you would like your body to be the three things mentioned in the title, this book can certainly help you get there.

End Your Carb Confusion – by Dr. Eric Westman & Amy Berger
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.
Carbs can indeed be confusing! We’ve written about it ourselves before, but there’s more to be said than fits in a single article, and sometimes a book is in order. This one is such a book.
The authors (an MD and a nutritionist) explain the ins and outs of carbohydrates of various kinds, insulin responses, and what that means for the body. They also then look at the partly-similar, partly-different processes that occur with the metabolism of fats of various kinds, and what that means for the body, too.
Ultimately they advocate for a simple and clear low-carb approach broadly consistent with keto diet macro principles, without getting too overly focused on “is this fruit/vegetable ok?” minutiae. This has the benefit of putting it well aside from the paleo diet, for example (which focuses more on pseudo-historical foods than it does on macros), and also makes it a lot easier on a practical level.
The style is very textbook-like, which makes for an easy read with plenty of information that should stick easily in most reader’s minds, rather than details getting lost in wall-of-text formatting. So, we approve of this.
There is not, by the way, a recipes section. It’s “here’s the information, now go forth and enjoy” and leaves us all to find/make our own recipes, rather than trying to guess our culinary preferences.
Bottom line: if you’d like an easy-to-read primer on understanding how carbs work, what it means for you, and what to do about it, then this is a fine book.

Wheat Belly, Revised & Expanded Edition – by Dr. William Davis
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.
This review pertains to the 2019 edition of the book, not the 2011 original, which will not have had all of the same research.
We are told, by scientific consensus, to enjoy plenty of whole grains as part of our diet. So, what does cardiologist Dr. William Davis have against wheat?
Firstly, not all grains are interchangeable, and wheat—in particular, modern strains of wheat—cannot be described as the same as the wheat of times past.
While this book does touch on the gluten aspect (and Celiac disease), and notes that modern wheat has a much higher gluten content than older strains, most of this book is about other harms that wheat can do to us.
Dr. Davis explores and explains the metabolic implications of wheat’s unique properties on organs such as our pancreas, liver, heart, and brain.
The book does also have recipes and meal plans, though in this reviewer’s opinion they were a little superfluous. Wheat is not hard to cut out unless you are living in a food desert or are experiencing food poverty, in which case, those recipes and meal plans would also not help.
Bottom line: this book, filled with plenty of actual science, makes a strong case against wheat, and again, mostly for reasons other than its gluten content. You might want to cut yours down!
