Everyone knows “B vitamins are for energy!” and that is definitely a theme, but there’s a lot more to it than that, and in some cases, there are big mistakes that people make when it comes to supplementing their diet.
First, let’s do a quick overview of what each of the B vitamins do, by number, and putting names to them:
B1 (Thiamine)
- Function: helps convert carbohydrates into energy, supports nerve function
- Forms: thiamine hydrochloride, thiamine mononitrate, benfotiamine (fat-soluble form)
- Example foods: lentils, sunflower seeds
B2 (Riboflavin)
- Function: supports energy production, skin health, and eye function, turns your pee fluorescent yellow (the latter is really only if you consume exciting amounts of it; this will usually occur from supplementation, not from normal diet)
- Forms: riboflavin, riboflavin-5’-phosphate
- Example foods: almonds, mushrooms
B3 (Niacin)
- Function: aids metabolism, supports skin, nerves, and cholesterol levels
- Forms: niacin (nicotinic acid), niacinamide (nicotinamide), inositol hexanicotinate (flush-free niacin)
- Example foods: whole grains, peanuts (literally the best nut for this)
B5 (Pantothenic Acid)
- Function: essential for fatty acid metabolism and hormone production
- Forms: pantothenic acid, calcium pantothenate, panthenol (alcohol form!)
- Example foods: it’s in pretty much everything (hence the name); it’s almost impossible to be deficient in this vitamin unless you are literally starving
B6 (Pyridoxine)
- Function: needed for red blood cell production, supports brain function, as well as specifically being a part of neurotransmitter production (including dopamine and serotonin, despite them being made in different places—the brain and the gut, respectively),
- Forms: pyridoxine hydrochloride, pyridoxal-5’-phosphate (active form)
- Example foods: bananas, potatoes
B7 (Biotin)
- Function: helps with fatty acid synthesis, skin, hair, and nail health
- Forms: d-biotin, biotinylated compounds of various kinds
- Example foods: fava beans, walnuts
B9 (Folate/Folic Acid)
- Function: crucial for DNA synthesis, cell division, and fetal development
- Forms: folic acid, folinic acid, 5-methyltetrahydrofolate (5-MTHF, active form)
- Example foods: chickpeas, spinach ← we only mentioned one leafy green here for fairness, but leafy greens in general are great sources of vitamin B9, hence the name, from the Latin “folium”, meaning leaf.
B12 (Cobalamin)
- Function: supports red blood cell formation, nerve function, and DNA synthesis
- Forms: cyanocobalamin, methylcobalamin (active), hydroxocobalamin (active), adenosylcobalamin (active)
- Example foods: nutritional yeast, nori
You may be wondering: what about vitamins B4, B8, B10, and B11? Those are now vacant spots, that once contained things that are no longer considered vitamins.
Three Critical Vitamin B Mistakes That May Be Sabotaging Your Health
Some mistakes that people make include:
Not supplementing when necessary
This occurs most often after midlife, especially in women, and the most common deficiencies are B1, B9, and B12.
See also: These Signs Often Mean These Nutrient Deficiencies (Do You Have Any?)
While it’s tempting to think “if I have a good balanced diet, I won’t need…” but the fact is sometimes our diet isn’t as nutrient dense as we hope—often through no fault of our own! But many modern farming methods prioritize yield over nutritional value, and that can result in plants and animals that do not have the nutritional qualities they “should”.
We wrote about this a while back, weighing up the “supplementation vs diet alone” dilemma:
Does Our Diet Need A Little Help? ← this also has a very useful chart of which vitamins people usually get too little or too much of. Note however that the statement of marginally excessive folate is slightly misleading, as the data pool contains men and women aged 18–65, while B9 is mostly needed more by women, and especially around childbirth or menopause, so B9 is actually a very common deficiency, but here it’s being balanced out lots of men getting too much (because every multivitamin has it).
Supplementing to excess
Most B vitamins have a very high maximum tolerable dose, because (with the exception of where we marked otherwise) they are water-soluble, which means that if you take more than you need, you’ll just pee it out later. Hence the famous fluorescence, for example.
However, the fat soluble form of vitamin B1 is harder to get in and harder to get out.
As for the others, problems usually only occur if you take enough to cause toxicity, faster than you pee it out. In other words, go easy on those Berocca drinks!
Nevertheless, there are other problems that can arise:
Vitamin B6 is essential—but too much can be toxic. Here’s what to know to stay safe ← tl;dr: there are issues with it causing peripheral neuropathy at doses over 10mg (the safe dose is disputed, so we’re mentioning the lowest safe dose here, but you can read about the others in the article)
Getting forms that don’t work so well
Those different forms we listed? They are not all created equal! For example:
- Folic acid is cheap; unfortunately, it’s not absorbed or used well
- Cyanocobalamin is cheap; unfortunately, it’s not absorbed or used well
Let us quote a recent book review of ours:
❝Rather, the most common forms of vitamins B9 and B12 provided in supplements are folic acid and cyanocobalamin, respectively, which as he demonstrates with extensive research to back up his claims, cannot be easily absorbed or used especially well.
About those vitamers: a vitamer is simply a form of a vitamin—most vitamins we need can arrive in a variety of forms. In the case of vitamins B9 and B12, he advocates for ditching vitamers folic acid and cyanocobalamin, cheap as they are, and springing for bioactive vitamers L-methylfolate, methylcobalamin, and adenosylcobalamin.
He also discusses (again, just as well-evidenced as the above things) why we might struggle to get enough from our diet after a certain age. For example, if trying to get these vitamins from meat, 50% of people over 50 cannot manufacture enough stomach acid to break down that protein to release the vitamins.
And as for methyl-B12 vitamers, you might expect you can get those from meat, and technically you can, but they don’t occur in all animals, just in one kind of animal. Specifically, the kind that has the largest brain-to-body ratio. However, eating the meat of this animal can result in protein folding errors in general and Creutzfeldt–Jakob disease in particular, so the author does not recommend eating humans, however nutritionally convenient that would be.
All this means that supplementation after a certain age really can be a sensible way to do it—but do it wisely, and pick the right vitamers.❞

We don’t sell them, but here for your convenience are example products on Amazon:
L-methylfolate (active form of vitamin B9)

“Slugging” Skin Care Routine (Tips From A Dermatologist)
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.
Dermatologist Dr. Jenny Liu weighs in with advice!
Sometimes simplest is best
Slugging is a skincare trend involving applying petrolatum (e.g. Vaseline) as the final step to lock in hydration and repair the skin barrier. It’s particularly useful for dry, sensitive, or eczema-prone skin, and/or damaged skin barriers from overuse of actives or harsh conditions.
How it works: the waterproof layer reduces water loss (up to 99%) and facilitates repair the skin barrier. Thus, it indirectly hydrates the skin, supports natural exfoliation, and reduces fine lines. Best of all, it’s non-irritating, non-comedogenic, and safe for all skin types.
How to do it:
- Cleanse thoroughly to remove makeup and impurities.
- Apply a moisturizer or serum with humectants (e.g. glycerin, hyaluronic acid).
- Seal with petrolatum (e.g. Vaseline or similar).
- Skip areas with stronger active ingredients (e.g. retinoids) and active acne areas.
- Apply 30–60 minutes before bed to reduce product transfer.
- Use a gentle cleanser in the morning to remove residue.

Sarah Raven’s Garden Cookbook – by Sarah Raven
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.
Note: the US Amazon site currently (incorrectly) lists the author as “Jonathan Buckley”. The Canadian, British, and Australian sites all list the author correctly as Sarah Raven, and some (correctly) credit Jonathan Buckley as the photographer she used.
First, what it’s not: a gardening book. Beyond a few helpful tips, pointers, and “plant here, harvest here” instructions, this book assumes you are already capable of growing your own vegetables.
She does assume you are in a temperate climate, so if you are not, this might not be the book for you. Although! The recipes are still great; it’s just you’d have to shop for the ingredients and they probably won’t be fresh local produce for the exact same reason that you didn’t grow them.
If you are in a temperate climate though, this will take you through the year of seasonal produce (if you’re in a temperate climate but it’s in for example Australia, you’ll need to make a six-month adjustment for being in the S. Hemisphere), with many recipes to use not just one ingredient from your garden at a time, but a whole assortment, consistent with the season.
About the recipes: they (which are 450 in number) are (as you might imagine) very plant-forward, but they’re generally not vegan and often not vegetarian. So, don’t expect that you’ll produce everything yourself—just most of the ingredients!
Bottom line: if you like cooking, and are excited by the idea of growing your own food but are unsure how regularly you can integrate that, this book will keep you happily busy for a very long time.

Older Men’s Connections Often Wither When They’re on Their Own
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 age 66, South Carolina physician Paul Rousseau decided to retire after tending for decades to the suffering of people who were seriously ill or dying. It was a difficult and emotionally fraught transition.
“I didn’t know what I was going to do, where I was going to go,” he told me, describing a period of crisis that began in 2017.
Seeking a change of venue, Rousseau moved to the mountains of North Carolina, the start of an extended period of wandering. Soon, a sense of emptiness enveloped him. He had no friends or hobbies — his work as a doctor had been all-consuming. Former colleagues didn’t get in touch, nor did he reach out.
His wife had passed away after a painful illness a decade earlier. Rousseau was estranged from one adult daughter and in only occasional contact with another. His isolation mounted as his three dogs, his most reliable companions, died.
Rousseau was completely alone — without friends, family, or a professional identity — and overcome by a sense of loss.
“I was a somewhat distinguished physician with a 60-page resume,” Rousseau, now 73, wrote in the Journal of the American Geriatrics Society in May. “Now, I’m ‘no one,’ a retired, forgotten old man who dithers away the days.”
In some ways, older men living alone are disadvantaged compared with older women in similar circumstances. Research shows that men tend to have fewer friends than women and be less inclined to make new friends. Often, they’re reluctant to ask for help.
“Men have a harder time being connected and reaching out,” said Robert Waldinger, a psychiatrist who directs the Harvard Study of Adult Development, which has traced the arc of hundreds of men’s lives over a span of more than eight decades. The men in the study who fared the worst, Waldinger said, “didn’t have friendships and things they were interested in — and couldn’t find them.” He recommends that men invest in their “social fitness” in addition to their physical fitness to ensure they have satisfying social interactions.
Slightly more than 1 in every 5 men ages 65 to 74 live alone, according to 2022 Census Bureau data. That rises to nearly 1 in 4 for those 75 or older. Nearly 40% of these men are divorced, 31% are widowed, and 21% never married.
That’s a significant change from 2000, when only 1 in 6 older men lived by themselves. Longer life spans for men and rising divorce rates are contributing to the trend. It’s difficult to find information about this group — which is dwarfed by the number of women who live alone — because it hasn’t been studied in depth. But psychologists and psychiatrists say these older men can be quite vulnerable.
When men are widowed, their health and well-being tend to decline more than women’s.
“Older men have a tendency to ruminate, to get into our heads with worries and fears and to feel more lonely and isolated,” said Jed Diamond, 80, a therapist and the author of “Surviving Male Menopause” and “The Irritable Male Syndrome.”
Add in the decline of civic institutions where men used to congregate — think of the Elks or the Shriners — and older men’s reduced ability to participate in athletic activities, and the result is a lack of stimulation and the loss of a sense of belonging.
Depression can ensue, fueling excessive alcohol use, accidents, or, in the most extreme cases, suicide. Of all age groups in the United States, men over age 75 have the highest suicide rate, by far.
For this column, I spoke at length to several older men who live alone. All but two (who’d been divorced) were widowed. Their experiences don’t represent all men who live alone. But still, they’re revealing.
The first person I called was Art Koff, 88, of Chicago, a longtime marketing executive I’d known for several years. When I reached out in January, I learned that Koff’s wife, Norma, had died the year before, leaving him hobbled by grief. Uninterested in eating and beset by unremitting loneliness, Koff lost 45 pounds.
“I’ve had a long and wonderful life, and I have lots of family and lots of friends who are terrific,” Koff told me. But now, he said, “nothing is of interest to me any longer.”
“I’m not happy living this life,” he said.
Nine days later, I learned that Koff had died. His nephew, Alexander Koff, said he had passed out and was gone within a day. The death certificate cited “end stage protein calorie malnutrition” as the cause.
The transition from being coupled to being single can be profoundly disorienting for older men. Lodovico Balducci, 80, was married to his wife, Claudia, for 52 years before she died in October 2023. Balducci, a renowned physician known as the “patriarch of geriatric oncology,” wrote about his emotional reaction in the Journal of the American Geriatrics Society, likening Claudia’s death to an “amputation.”
“I find myself talking to her all the time, most of the time in my head,” Balducci told me in a phone conversation. When I asked him whom he confides in, he admitted, “Maybe I don’t have any close friends.”
Disoriented and disorganized since Claudia died, he said his “anxiety has exploded.”
We spoke in late February. Two weeks later, Balducci moved from Tampa to New Orleans, to be near his son and daughter-in-law and their two teenagers.
“I am planning to help as much as possible with my grandchildren,” he said. “Life has to go on.”
Verne Ostrander, a carpenter in the small town of Willits, California, about 140 miles north of San Francisco, was reflective when I spoke with him, also in late February. His second wife, Cindy Morninglight, died four years ago after a long battle with cancer.
“Here I am, almost 80 years old — alone,” Ostrander said. “Who would have guessed?”
When Ostrander isn’t painting watercolors, composing music, or playing guitar, “I fall into this lonely state, and I cry quite a bit,” he told me. “I don’t ignore those feelings. I let myself feel them. It’s like therapy.”
Ostrander has lived in Willits for nearly 50 years and belongs to a men’s group and a couples’ group that’s been meeting for 20 years. He’s in remarkably good health and in close touch with his three adult children, who live within easy driving distance.
“The hard part of living alone is missing Cindy,” he told me. “The good part is the freedom to do whatever I want. My goal is to live another 20 to 30 years and become a better artist and get to know my kids when they get older.”
The Rev. Johnny Walker, 76, lives in a low-income apartment building in a financially challenged neighborhood on Chicago’s West Side. Twice divorced, he’s been on his own for five years. He, too, has close family connections. At least one of his several children and grandchildren checks in on him every day.
Walker says he had a life-changing religious conversion in 1993. Since then, he has depended on his faith and his church for a sense of meaning and community.
“It’s not hard being alone,” Walker said when I asked whether he was lonely. “I accept Christ in my life, and he said that he would never leave us or forsake us. When I wake up in the morning, that’s a new blessing. I just thank God that he has brought me this far.”
Waldinger recommended that men “make an effort every day to be in touch with people. Find what you love — golf, gardening, birdwatching, pickleball, working on a political campaign — and pursue it,” he said. “Put yourself in a situation where you’re going to see the same people over and over again. Because that’s the most natural way conversations get struck up and friendships start to develop.”
Rousseau, the retired South Carolina doctor, said he doesn’t think about the future much. After feeling lost for several years, he moved across the country to Jackson, Wyoming, in the summer of 2023. He embraced solitude, choosing a remarkably isolated spot to live — a 150-square-foot cabin with no running water and no bathroom, surrounded by 25,000 undeveloped acres of public and privately owned land.
“Yes, I’m still lonely, but the nature and the beauty here totally changed me and focused me on what’s really important,” he told me, describing a feeling of redemption in his solitude.
Rousseau realizes that the death of his parents and a very close friend in his childhood left him with a sense of loss that he kept at bay for most of his life. Now, he said, rather than denying his vulnerability, he’s trying to live with it. “There’s only so long you can put off dealing with all the things you’re trying to escape from.”
It’s not the life he envisioned, but it’s one that fits him, Rousseau said. He stays busy with volunteer activities — cleaning tanks and running tours at Jackson’s fish hatchery, serving as a part-time park ranger, and maintaining trails in nearby national forests. Those activities put him in touch with other people, mostly strangers, only intermittently.
What will happen to him when this way of living is no longer possible?
“I wish I had an answer, but I don’t,” Rousseau said. “I don’t see my daughters taking care of me. As far as someone else, I don’t think there’s anyone else who’s going to help me.”

Black Coffee vs Orange Juice – 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 black coffee to orange juice, we picked the coffee.
Why?
While this one isn’t a very like-for-like choice, it’s a choice often made, so it bears examining.
In favor of the orange juice, it has vitamins A and C and the mineral potassium, while the coffee contains no vitamins or minerals beyond trace amounts.
However, to offset that: drinking juice is one of the worst ways to consume sugar; the fruit has not only been stripped of its fiber, but also is in its most readily absorbable state (liquid), meaning that this is going to cause a blood sugar spike, which if done often can lead to insulin resistance, type 2 diabetes, non-alcoholic fatty liver disease, and more. Now, the occasional glass of orange juice (and resultant blood sugar spike) isn’t going to cause disease by itself, but everything we consume tips the scales of our health towards wellness or illness (or sometimes both, in different ways), and in this case, juice has a rather major downside that ought not be ignored.
In favor of the coffee, it has a lot of beneficial phytochemicals (mostly antioxidant polyphenols of various kinds), with no drawbacks worth mentioning unless you have a pre-existing condition of some kind.
Coffee can of course be caffeinated or decaffeinated, and we didn’t specify which here. Caffeine has some pros and cons that at worst, balance each other out, and whether or not it’s caffeinated, there’s nothing in coffee to offset the beneficial qualities of the antioxidants we mentioned before.
Obviously, in either case we are assuming consuming in moderation.
In short:
- orange juice has negatives that at least equal, if not outweigh, its positives
- coffee‘s benefits outweigh any drawbacks for most people

Cranberries vs Goji Berries – 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 cranberries to goji berries, we picked the cranberries.
Why?
Both are great! And your priorities may differ. Here’s how they stack up:
In terms of macros, goji berries have more protein, carbs, and fiber. This is consistent with them generally being eaten very dried, whereas cranberries are more often eaten fresh or from frozen, or partially rehydrated. In any case, goji berries are the “more food per food” option, so it wins this category. The glycemic indices are both low, by the way, though goji berries are the lower.
When it comes to vitamins, cranberries have more of vitamins B1, B2, B3, B5, B6, B9, E, K, and choline, while goji berries have more of vitamins A and C. Admittedly it’s a lot more, but still, on strength of overall vitamin coverage, the clear winner here is cranberries.
We see a similar story when it comes to minerals: cranberries have more copper, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while goji berries have (a lot) more calcium and iron. Again, by strength of overall mineral coverage, the clear winner here is cranberries.
Cranberries do also have some extra phytochemical benefits, including their prevention/cure status when it comes to UTIs—see our link below for more on that.
At any rate, enjoy either or both, but those are the strengths and weaknesses of these two berries!

The Diabetes Drugs That Can Cut Asthma Attacks By 70%
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.
Asthma, obesity, and type 2 diabetes are closely linked, with the latter two greatly increasing asthma attack risk.
While bronchodilators / corticosteroids can have immediate adverse effects due to sympathetic nervous system activation, and lasting adverse effects due to the damage it does to metabolic health, diabetes drugs, on the other hand, can improve things with (for most people) fewer unwanted side effects.
Great! Which drugs?
Metformin, and glucagon-like peptide-1 receptor agonists (GLP-1RAs).
Specifically, researchers have found:
- Metformin is associated with a 30% reduction in asthma attacks
- GLP-1RAs are associated with a 40% reduction in asthma attacks
…and yes, they stack, making for a 70% reduction in the case of people taking both. Furthermore, the results are independent of weight, glycemic control, or asthma phenotype.
In terms of what was counted, the primary outcome was asthma attacks at 12-month follow-up, defined by oral corticosteroid use, emergency visits, hospitalizations, or death.
The effect of metformin on asthma attacks was not affected by BMI, HbA1c levels, eosinophil count, asthma severity, or sex.
Of the various extra antidiabetic drugs trialled in this study, only GLP-1 receptor agonists showed a further and sustained reduction in asthma attacks.
Here’s the study itself, hot off the press, published on Monday:
JAMA Int. Med. | Antidiabetic Medication and Asthma Attacks
“But what if I’m not diabetic?”
Good news:
More than half of all US adults are eligible for semaglutide therapy ← this is because they’ve expanded the things that semaglutide (the widely-used GLP-1 receptor agonist drug) can be prescribed for, now going beyond just diabetes and/or weight loss 😎
And metformin, of course, is more readily available than semaglutide, so by all means speak with your doctor/pharmacist about that, if it’s of interest to you.
Take care!
