Are Your Vitamin D Supplements Working? Probably Not (Here’s Why & How To Fix It)

Most people over a certain age know the importance of maintaining good vitamin D levels, especially in the context of bone health (as vitamin D is instrumental in how the body processes calcium).
Most people don’t know that you also need a good amount of vitamin K, or else that calcium is going to get stuck in your arteries instead of getting to your bones.
You can read about that, here: Vitamin K2 And The Calcium Paradox
There are other popular misconceptions about vitamin D, which you can read about here: Debunking the vitamin D fad
And yes, you can still overdo it: Vit D + Calcium: Too Much Of A Good Thing?
And there are even more ways to mess it up! See: How Taking Vitamin D Supplements Can Sabotage Your Vitamin D Levels
Which latter is mostly because of people making mistakes in the category of: Vitamin D2 vs Vitamin D3: What You Would Benefit From Knowing

In the US, many people rely on milk for calcium. Some notes about that to get us started:
- Milk is a rich source of calcium, which is useless to the body if you don’t also have good levels of vitamin D and magnesium.
- People’s vitamin D levels tend to directly correlate to the level of sun where they live, if supplementation isn’t undertaken.
- Plant-based milks are usually fortified with vitamin D (and calcium), by the way.
- Most Americans* are deficient in magnesium, because green leafy things don’t form as big a part of most people’s diets as they should.
*magnesium deficiency is very common, and around 80% of people in the US do not meet the RDA for magnesium, despite widespread attention to vitamin D insufficiency.

Now, with this in mind, researchers (Dr. Xiangzhu Zhu et al.) investigated the relationship between magnesium (Mg) levels and vitamin D synthesis and vitamin D metabolism.
That latter is important, because your body can be full to the brim with vitamin D, but if you can’t metabolize it, it’s useless to you.
What Dr. Zhu and her team found is that magnesium is seen to regulate vitamin D like a thermostat—raising levels when they are low and lowering them when they are high, which suggests an explanation for why vitamin D supplements do not work consistently across people.
In a randomized, placebo-controlled trial with 239 adults, tailoring magnesium doses to participants’ usual dietary intake, and found that magnesium supplementation increased vitamin D in participants who were deficient but reduced vitamin D in those who already had high levels, suggesting an optimizing rather than a purely boosting effect.

If you prefer to get your nutrients from food rather than supplements, then magnesium intake at recommended levels can usually be enjoyed through foods such as dark leafy greens, beans, whole grains, nuts, avocados, and even dark chocolate.

As for why you might want to favor getting it from food if you can, then while the title says “vitamins”, this book discusses an assortment of vitamins, minerals, and other nutrients; the “other nutrients” category including amino acids (branched chain and essential), prebiotics and probiotics, and triglycerides of various kinds:

Cherries vs Pomegranate – 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 cherries to pomegranate, we picked the pomegranate.
Why?
In terms of macros, pomegranate is slightly higher in carbs, and/but 4x higher in fiber. That’s already a good start for pomegranates. Lest we be accused of cherry-picking, though, we’ll mention that pomegranate is also slightly higher in protein and fat, for what it’s worth—which is not a lot. As with most fruits, the protein and fat numbers are low importance next to the carb:fiber ratio, and as with most fruits, the carb:fiber ratio is fine for both here.
When it comes to vitamins, cherries have more of vitamins A and B3, while pomegranate has more of vitamins B1, B2, B5, B6, B9, E, and K. The two fruits are equal in vitamin C. This all makes for a clear win for pomegranate in this category.
In the category of minerals, cherries have slightly more calcium, while pomegranate boasts more copper, magnesium, phosphorus, potassium, selenium, and zinc. Another win for pomegranate!
In other considerations, each of these fruits have beneficial polyphenols, each with a slightly different profile, but neither pressingly better than the other. They also both have special properties of their own—see the “learn more” links below to find out about these! Meanwhile though, we’re calling this round a tie.
Adding up the sections makes for a clear overall win for pomegranate, but by all means enjoy either or both, as diversity is great!

What To Say When You Talk To Your Self – by Dr. Shad Helmstetter
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 sometimes said that your brain, and by extension the rest of your body, is listening to everything you say—including, of course, what you say just in your head.
So, how can we best make use of that? Dr. Helmstetter covers a lot more than just “be nice to yourself”, and discusses how to change habits and rewire attitude, solve problems and overcome personal growth stasis, and also how to navigate the nuances of situational self-talk, while keeping to the principle that “if it isn’t simple, it won’t work”.
The style is a little more personal than one might expect; notwithstanding the title being about what to say when you talk to yourself, the pronoun “I” is the one the author uses rather more than “you”, giving many examples of how he has done things, and telling stories involving himself. This is all illustrative and helpful, so it’s not a problem, just an interesting choice that may alienate some readers.
In the category of subjective criticism, the book is quite repetitive; it seems Dr. Helmstetter goes for the P. T. Barnum approach of “tell them what you’re going to tell them, tell them, and then tell them what you’ve told them”, and repeats a few extra times to be sure. So, for those who find that repetition indeed helps learning, this book will very much fulfil that preference.
Bottom line: if you’d like to improve your self-talk to re-write your brain for the better, then this book will walk you through the processes very thoroughly indeed.

Dodging Dengue In The US
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.
Dengue On The Rise
We wrote recently about dengue outbreaks in the Americas, with Puerto Rico declaring an epidemic. Cases are now being reported in Florida too, and are likely to spread, so it’s good to be prepared, if your climate is of the “warm and humid” kind.
If you want to catch up on the news first, here you go:
- UN health agency cites tenfold increase in reported cases of dengue over the last generation
- Puerto Rico has declared an epidemic following a spike in dengue cases
- Dengue fever confirmed in Florida Keys as US on watch for rise in mosquito illness
Note: dengue is far from unheard of in Florida, but the rising average temperatures in each year mean that each year stands a good chance of seeing more cases than the previous. It’s been climbing since at least 2017, took a dip during the time of COVID restrictions keeping people at home more, and then for the more recent years has been climbing again since.
What actually is it?
Dengue is a viral, mosquito-borne disease, characterized by fever, vomiting, muscle pain, and a rash, in about 1 in 4 cases.
Which can sound like “you’ll know if you have it”, but in fact it’s usually asymptomatic for a week or more after infection, so, watch out!
What next, if those symptoms appear?
The good news is: the fever will usually last less than a week
The bad news is: a day or so after that the fever subsided, the more serious symptoms are likely to start—if they’re going to.
If you’re unlucky enough to be one of the 1 in 20 who get the serious symptoms, then you can expect abdominal cramps, repeat vomiting, bleeding from various orifices (you may not get them all, but all are possible), and (hardly surprising, given the previous items) “extreme fatigue and restlessness”.
If you get those symptoms, then definitely get to an ER as soon as possible, as dengue can become life-threatening within hours of such.
Read more: CDC | Symptoms of Dengue and Testing
While there is not a treatment for dengue per se, the Emergency Room will be better able to manage your symptoms and thus keep you alive long enough for them to pass.
If you’d like much more detail (on symptoms, seriousness, at-risk demographics, and prognosis) than what the CDC offers, then…
Read more: BMJ | Dengue Fever
Ok, so how do we dodge the dengue?
It sounds flippant to say “don’t get bitten”, but that’s it. However, there are tips are not getting bitten:
- Use mosquito-repellent, but it has to contain >20% DEET, so check labels
- Use mosquito nets where possible (doors, windows, etc, and the classic bed-tent net is not a bad idea either)
- Wear clothing that covers your skin, especially during the day—it can be light clothing; it doesn’t need to be a HazMat suit! But it does need to reduce the area of attack to reduce the risk of bites.
- Limit standing water around your home—anything that can hold even a small amount of standing water is a potential mosquito-breeding ground. Yes, even if it’s a crack in your driveway or a potted bromeliad.

The Kitchen Doctor
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.
Dr. Rupy Aujla: The Kitchen Doctor
This is Dr. Rupy Aujla, and he’s a medical doctor. He didn’t set out to become a “health influencer”.
But then, a significant heart condition changed his life. Having a stronger motivation to learn more about nutritional medicine, he did a deep dive into the scientific literature, because that’s what you do when your life is on the line, especially if you’re a doctor!
Using what he learned, he was able to reverse his condition using a food and lifestyle approach. Now, he devotes himself to sharing what he learned—and what he continues to learn as he goes along.
One important thing he learned because of what happened to him, was that he hadn’t been paying enough attention to what his body was trying to tell him.
He wants us to know about interoception—which isn’t a Chris Nolan movie. Rather, interoception is the sense of what is going on inside one’s own body.
The counterpart of this is exteroception: our ability to perceive the outside world by means of our various senses.
Interoception is still using the senses, but is sensing internal body sensations. Effectively, the brain interprets and integrates what happens in our organs.
When interoception goes wrong, researchers found, it can lead to a greater likelihood of mental health problems. Having an anxiety disorder, depression, mood disorder, or an eating disorder often comes with difficulties in sensing what is going on inside the body.
Improving our awareness of body cues
Those same researchers suggested therapies and strategies aimed at improving awareness of mind-body connections. For example, mindfulness-based stress reduction, yoga, meditation and movement-based treatments. They could improve awareness of body cues by attending to sensations of breathing, cognitions and other body states.
But where Dr. Aujla puts his focus is “the heart of the home”, the kitchen.
The pleasure of food
❝Eating is not simply ingesting a mixture of nutrients. Otherwise, we would all be eating astronaut food. But food is not only a tool for health. It’s also an important pleasure in life, allowing us to connect to others, the present moment and nature.❞
Dr. Rupy Aujla
Dr. Aujla wants to help shift any idea of a separation between health and pleasure, because he believes in food as a positive route to well-being, joy and health. For him, it starts with self-awareness and acceptance of the sensory pleasures of eating and nourishing our bodies, instead of focusing externally on avoiding perceived temptations.
Most importantly:
We can use the pleasure of food as an ally to healthy eating.
Instead of spending our time and energy fighting the urge to eat unhealthy things that may present a “quick fix” to some cravings but aren’t what our body actually wants, needs, Dr. Aujla advises us to pay just a little more attention, to make sure the body’s real needs are met.
His top tips for such are:
- Create an enjoyable relaxing eating environment
To help cultivate positive emotions around food and signal to the nervous system a shift to food-processing time. Try setting the table with nothing else on it beyond what’s relevant to the dinner, putting away distractions, using your favorite plates, tablecloth, etc.
- Take 3 deep abdominal breaths before eating
To help you relax and ground yourself in the present moment, which in turn is to prepare your digestive system to receive and digest food.
- Pay attention to the way you sit
Take some time to sit comfortably with your feet grounded on the floor, not slouching, to give your stomach space to digest the food.
- Appreciate what it took to bring this food to your plate
Who was involved in the growing process and production, the weather and soil it took to grow the food, and where in the world it came from.
- Enjoy the sensations
When you’re cooking, serving, and eating your food, be attentive to color, texture, aroma and even sound. Taste the individual ingredients and seasonings along the way, when safe and convenient to do so.
- Journal
If you like journaling, you can try adding a mindful eating section to that. Ask questions such as: “how did I feel before, during, and after the meal?”
In closing…
Remember that this is a process, not only on an individual level but as a society too.
Oftentimes it’s hard to eat healthily… We can be given to wonder even “what is healthy, after all?”, and we can be limited by what is available, what is affordable, and what we have time to prepare.
But if we make a conscious commitment to make the best choices we reasonably can as we go along, then small changes can soon add up.

Cabbage vs Cauliflower – 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 cabbage to cauliflower, we picked the cauliflower.
Why?
First, let’s note: these are two different cultivars of the same species (Brassica oleracea) and/but as usual (we say, as there are a lot of cultivars of Brassica oleracea, and we’ve done a fair few pairings of them before) there are still nutritional differences to consider, such as…
In terms of macros, cabbage has very slightly more carbs and fiber, while cauliflower has very slightly more protein. However, the numbers are all so close (and the glycemic index equal), such that we’re going to call the macros category a tie.
In the category of vitamins, cabbage has more of vitamins A, B1, E, and K, while cauliflower has more of vitamins B2, B3, B5, B6, B7, B9, C, and choline. Superficially, this is a clear 8:4 win for cauliflower; it’s worth noting though that the differences in amounts are mostly small, so this isn’t as big a win as it looks like. Still a win for cauliflower, though.
When it comes to minerals, it’s a similar story: cabbage has a little more calcium, iron, and manganese, while cauliflower has a little more copper, magnesium, phosphorus, potassium, and zinc. This time a 6:3 win for cauliflower, and again, the margins are small so there’s really not as much between them as it looks like. Still a win for cauliflower, though.
In short: enjoy either or both (diversity is good), but the most nutritionally dense is cauliflower, even if cabbage isn’t far behind it.

Hearty Healthy Ragù
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.
Ragù is a traditional Italian meaty sauce with tomato, and is the base for a number of other Italian dishes. It can be enjoyed as-is, or with very minor modifications can be turned into a Bolognese sauce or a lasagna filling or various other things. Our variations from tradition are mainly twofold here: we’re using nutrition-packed lentils instead of meat (but with a couple of twists that make them meatier), and we’re not using wine.
Traditionally, red wine is used in a ragù (white wine if you want to make it into a Bolognese sauce, by the way), but with all we’re doing it’s not necessary. If you want to add a splash of wine, we’re not going to call that a healthy ingredient, but we’re also not the boss of you
You will need
- 1 large onion (or equivalent small ones), chopped roughly
- 1 bulb garlic (or to your heart’s content), chopped finely or crushed
- 4 large tomatoes, chopped (or 2 cans chopped tomatoes)
- 1 tube (usually about 7 oz) tomato purée
- 1 cup brown lentils (green lentils will do if you can’t get brown)
- 1 tbsp chia seeds
- 1 tbsp black pepper, cracked or coarse ground
- 1 bunch fresh basil, finely chopped (or 1 tbsp, freeze-dried)
- 1 bunch fresh oregano, finely chopped (or 1 tbsp, freeze-dried)
- 1 tbsp nutritional yeast (failing that, 1 tbsp yeast extract, yes, even if you don’t like it, we promise it won’t taste like it once it’s done; it just makes the dish meatier in taste and also adds vitamin B12)
- 1 tsp cumin, ground (note that this one was tsp, not tbsp like the others)
- 1 tsp MSG, or 2 tsp low-sodium salt
- 4 cups water
- Olive oil for frying (ideally Extra Virgin, but so long as it’s at least marked virgin olive oil and not cut with other oils, that’s fine)
- Parsley, chopped, to garnish
Method
(we suggest you read everything at least once before doing anything)
1) Put the lentils in a small saucepan, or if you have one, a rice cooker (the rice cooker is better; works better and requires less attention), adding the chia seeds, MSG or low sodium salt, and nutritional yeast (or yeast extract). as well as the cumin. Add 4 cups boiling water and turn on the heat to cook them. This will probably take about 15–20 minutes; you want the lentils to be soft; a tiny bit past al dente, but not so far as mushy.
2) Fry the onion in some olive oil in a big pan (everything is going in here eventually if the pan is big enough; if it isn’t, you’ll need to transfer to a bigger pan in a bit). Once they’re nearly done, throw in the garlic too. If the lentils aren’t done yet, take the onions and garlic off the heat while you wait. After a few times of doing this recipe, you’ll be doing everything like clockwork and it’ll all align perfectly.
3) Drain the lentils (if all the water wasn’t absorbed; again, after doing it a few times, you’ll just use the right amount of water for your apparatus) but don’t rinse them (remember you put seasonings in here!), and add them to the pan with the onions and garlic; add a splash more olive oil if necessary, and stir until all the would-be-excess fat is absorbed into the lentils.
Note: the excess fat to be absorbed by the lentils was a feature not a bug; we wanted a little fat in the lentils! Makes the dish meatier and tastier, as well as more nutrient-dense.
4) add the tomatoes and tomato purée, stirring them in thoroughly; add the basil and oregano too and stir those in as well. Set it on a low heat for at least 10–15 minutes, stirring occasionally to let the flavors blend.
(if you happen to be serving pasta with it, then the time it takes to boil water and cook the pasta is a good time for the flavors to do their thing)
5) take it off the heat, and add the parsley garnish. It’s done!
Enjoy!
