Double Board-Certified Dermatologists Dr. Muneeb Shah & Dr. Luke Maxfield weigh in on vitamin C; is it worth the hype?
Yes it is, but…
There are some caveats, for example:
- It’s best to apply vitamin C on clean, dry skin and let it set before layering other products.
- Avoid mixing with oxidants like benzoyl peroxide (cancels out antioxidant effects).
- Avoid combining with copper (may negate brightening benefits).
- Do not use with hypochlorous acid (oxidative reactions cancel out benefits).
- Be cautious with retinol due to irritation risks.
However, used correctly, it does give very worthy benefits, and they recommend:
- Morning use: acts as an antioxidant, pairs well with sunscreen for better protection from sun and environmental damage.
- Night use: maximizes functions like improving tone, collagen production, texture, and reducing wrinkles.
That’s not to say that at night it stops being an antioxidant or during the day it isn’t critical for collagen synthesis, but it is to say: because of the different things our bodies typically encounter and/or do during the day or night, those are the best times to get the most out of those benefits.
They also review some popular products; here are some notes on their comments about them:
- Skinceuticals C E Ferulic: research-backed, $180, effective but potentially irritating.
- Skinceuticals Phloretin CF: includes 0.5% salicylic acid, good for acne-prone skin.
- Dermatology Vitamin C E Ferulic: relatively more affordable ($70), fragrance-free, includes peptides and ceramides.
- Drunk Elephant C-Firma: powder-to-serum formula, sued for patent infringement.
- Paula’s Choice C15 Booster: reformulated, fragrance-free, similar to Skinceuticals.
- Neutrogena Vitamin C Capsules: stabilized 20% ascorbic acid, single-use, travel-friendly.
- La Roche-Posay Vitamin C Serum: contains fragrance and alcohol, not ideal for sensitive skin.
- Matter of Fact Vitamin C Serum: includes ascorbic acid and ferulic acid, oily texture for dry skin.
- Medik8 Super C Ferulic: stable 30% ethyl ascorbic acid, lightweight texture.
- Naturium Vitamin C Complex: multi-form Vitamin C with niacinamide, alpha arbutin, and turmeric.
- Timeless Vitamin C Serum: affordable ($20), 20% ascorbic acid with E and ferulic acid.

Take These To Lower Cholesterol! (Statin Alternatives)
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. Ada Ozoh, a diabetes specialist, took an interest in this upon noting the many-headed beast that is metabolic syndrome means that neither diabetes nor cardiovascular disease exist in a vacuum, and there are some things that can help a lot against both. Here she shares some of her top recommendations:
Statin-free options
Dr. Ozoh recommends:
- Bergamot: lowers LDL (“bad” cholesterol) by about 30% and slightly increases HDL (“good” cholesterol), at 500–1000mg/day, seeing results in 1–6 months
- Berberine: prevents fat absorption and helps burn stored fat, as well as reducing blood sugar levels and blood pressure, at 1,500mg/day
- Silymarin: protects the liver, and lowers cholesterol in type 2 diabetes, at 280–420mg/day
- Phytosterols: lower cholesterol by about 10%; found naturally in many plants, but it takes supplementation to read the needed (for this purpose) dosage of 2g/day
- Red yeast rice: this is white rice fermented with yeast, and it lowers LDL cholesterol by about 25%, seeing results in around 3 months

Better Sex Through Mindfulness – by Dr. Lori Brotto
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.
Female sexuality is such a taboo topic that, if one searches for (ob/gyn professor, women’s health research director, and psychologist) Dr. Brotto’s book on Google or Amazon, it suggests only “lori brotto mindfulness book”. So, for those brave enough to read a book that would have shocked Victorians, what does this one contain?
The focus is on, as the title suggests, better sex, by and for women. That said, it’s mostly because typically women are more likely to experience the problems described in the book; it’s nothing actually intrinsic to womanhood. A man with the same problems could read this book and benefit just the same.
While the book covers many possible problems between the sheets, the overarching theme is problems of the mind, such as:
- Not getting into the mood in the first place
- Losing the mood quickly and easily, such as by becoming distracted
- Difficulty achieving orgasm even when mechanically everything’s delightful
- Physical discomfort creating a barrier to enjoyment
…and yes, that last one is in part mind-stuff too! Though Dr. Brotto isn’t arguing that mindfulness is a panacea, just an incredibly useful tool. And, it’s one she not only explains very well, but also explains from the position of a wealth of scientific evidence… Enough so, that we see a one-star Amazon reviewer from Canada complained that it was too well-referenced! For us, though, it’s what we like to see.
Good science, presented clearly and usefully, giving practical tips that improve people’s lives.
Bottom line: if you’ve ever lost the mood because you got distracted into thinking about taxes or that meeting on Tuesday, this is the book for you.

The Vagus Nerve’s Power for Weight Loss
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. Arun Dhir is a university lecturer, a gastrointestinal surgeon, an author, and a yoga and meditation instructor, and he has this to say:
Gut feelings
The vagus nerve is the 10th cranial nerve, also known as “vagus” (“the wanderer”), because it travels from the brain to many other body parts, including the ears, throat, heart, respiratory system, gut, pancreas, liver, and reproductive system. It’s no surprise then, that it plays a key role in brain-gut communication and metabolism regulation.
The vagus nerve is part of the parasympathetic nervous system, responsible for rest, digestion, and counteracting the stress response. Most signals through the vagus nerve travel from the gut to the brain, though there is communication in both directions.
You may be beginning to see how this works and its implications for weight management: the vagus nerve senses metabolites from the liver, pancreas, and small intestine, and regulates insulin production by stimulating beta cells in the pancreas, which is important for avoiding/managing insulin resistance and metabolic syndrome in general.
Dr. Dhir cites a study in which vagus nerve stimulation (originally used for treating epilepsy and depression) was shown to cause unintentional weight loss (6-11%) in patients, revealing a link to weight management. Of course, that is quite a specific sample, so more research is needed to say for sure, but because the principle is very sound and the mechanism of action is clear, it’s not being viewed as a controversial conclusion.
As for how get these benefits, here are seven ways:
- Cold water on the face: submerge your face in cold water in the morning while holding water in your mouth, or cover your face with a cold wet washcloth (while holding your breath please; no need to waterboard yourself!), which activates the “mammalian dive response” in which your body activates the parasympathetic nervous system in order to remain calm and thus survive for longer underwater
- Alternate hot and cold showers: switch between hot and cold water during showers for 10-second intervals; this creates eustress and activates the process of hormesis, improving your overall stress management and reducing any chronic stress response you may otherwise have going on
- Humming and gargling: the vibrations in the throat stimulate the nearby vagus nerve
- Deep breathing (pranayama): yoga breathing exercises, especially combined with somatic exercises such as the sun salutation, can stimulate the vagus nerve
- Intermittent fasting: helps recalibrate the metabolism and indirectly improves vagus nerve function
- Massage and acupressure: stimulates lymphatic channels and the vagus nerve
- Long walks in nature (“forest bathing”): helps trigger relaxation in general

Nutritional Profiles to Recipes
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I like the recipes. Most don’t seem to include nutritional profile. would lilke to see that. Macro/micro world…. Thank you❞
We’re glad you’re enjoying them! There are a couple of reasons why we don’t, but the reasons can be aggregated into one (admittedly rare) concept: honesty
To even try to give you these figures, we’d first need to use the metric system (or at least, a strictly mass-based system) which would likely not go well with our largely American readership, because “half a bulb of garlic, or more if you like”, and “1 cucumber” or “1 cup chopped carrot” could easily way half or twice as much, depending on the sizes of the vegetables or the chopping involved, and in the case of chopped vegetables measured by the cup, even the shape of the cup (because of geometry and the spaces left; it’s like Tetris in there). We can say “4 cups low-sodium broth” but we can’t say how much sodium is in your broth. And so on.
And that’s without getting into the flexibility we offer with substitutions, often at a rate of several per recipe.
We’d also need to strictly regulate your portion sizes for you, because we (with few exceptions, such as when they are a given number of burger patties, or a dessert-in-a-glass, etc) give you a recipe for a meal and leave it to you how you divide it and whether there’s leftovers.
Same goes for things like “Extra virgin olive oil for frying”; a recipe could say to use “2 tbsp” but let’s face it, you’re going to use what you need to use, and that’s going to change based on the size of your pan, how quickly it’s absorbed into the specific ingredients that you got, which will change depending on how fresh they are, and things like that.
By the time we’ve factored in your different kitchen equipment, how big your vegetables are, the many factors effecting how much oil you need, substitutions per recipe per making something dairy-free, or gluten-free, or nut-free, etc, how big your portion size is (we all know that “serves 4” is meaningless in reality)… Even an estimated average would be wildly misleading.
So, in a sea of recipes saying “500 kcal per serving” from the same authors who say you can caramelize onions in 4–5 minutes “or until caramelized” and then use the 4–5 minutes figure for calculating the overall recipe time… We prefer to stay honest.
PS: for any wondering, caramelizing onions takes closer to 45 minutes than 4–5 minutes, and again will depend on many factors, including the onions, how finely you chopped them, the size and surface of your pan, the fat you’re using, whether you add sugar, what kind, how much you stir them, the mood of your hob,
and the phase of the moon. Under very favorable circumstances, it could conceivably be rushed in 20 minutes or so, but it could also take 60. Slow-cooking them (i.e. in a crock pot) over 3–4 hours is a surprisingly viable “cheat” option, by the way. It’ll take longer, obviously, but provided you plan in advance, they’ll be ready when you need them, and perfectly done (the same claim cannot be made if you budgeted 4–5 minutes because you trusted a wicked and deceitful author who wants to poop your party).Take care!

Statins: Study Insights

It’s Q&A Day at 10almonds!
Q: Can you let us know about more studies that have been done on statins? Are they really worth taking?
That is a great question! We imagine it might have been our recent book recommendation that prompted it? It’s quite a broad question though, so we’ll do that as a main feature in the near future!

Goji Berries: Which Benefits Do They Really Have?
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.
Are Goji Berries Really A Superfood?
Goji berries are popularly considered a superfood, and sold for everything from anti-aging effects, to exciting benefits* that would get this email directed to your spam folder if we described them.
*We searched so you don’t have to: there doesn’t seem to be much research to back [that claim that we can’t mention], but we did find one paper on its “invigorating” benefits for elderly male rats. We prefer to stick to human studies where we can!
So how does the science stack up for the more mainstream claims?
Antioxidant effects
First and most obvious for this fruit that’s full of helpful polysaccharides, carotenoids, phenolic acids, and flavonoids, yes, they really do have strong antioxidant properties:
Immune benefits
Things that are antioxidant are generally also anti-inflammatory, and often have knock-on benefits for the immune system. That appears to be the case here.
For example, in this small-but-statistically-significant study (n=60) in healthy adults (aged 55–72 years)
❝The GoChi group showed a statistically significant increase in the number of lymphocytes and levels of interleukin-2 and immunoglobulin G compared to pre-intervention and the placebo group, whereas the number of CD4, CD8, and natural killer cells or levels of interleukin-4 and immunoglobulin A were not significantly altered. The placebo group showed no significant changes in any immune measures.
Whereas the GoChi group showed a significant increase in general feelings of well-being, such as fatigue and sleep, and showed a tendency for increased short-term memory and focus between pre- and post-intervention, the placebo group showed no significant positive changes in these measures.❞
“GoChi” here is a brand name for goji berries, and it’s not clear from the abstract whether the company funded the study:
Here’s another study, this time n=150, and ages 65–70 years old. This time it’s with a different brand (“Lacto-Wolfberry”, a milk-with-goji supplement drink) and it’s also unclear whether the company funded the study. However, taking the data at face value:
❝In conclusion, long-term dietary supplementation with Lacto-Wolfberry in elderly subjects enhances their capacity to respond to antigenic challenge without overaffecting their immune system, supporting a contribution to reinforcing immune defense in this population. ❞
In other words: it allowed those who took it to get measurably more benefit from the flu vaccinations that they received, without any ill effects.
Anticancer potential
This one’s less contentious (the immune benefits seemed very credible; we’d just like to see more transparent research to say for sure), so in the more clearly-evidenced case against cancer we’ll just drop a few quick studies, clipped for brevity:
- Goji berry (Lycium barbarum) inhibits the proliferation, adhesion, and migration of oral cancer cells
- A closer look at immunomodulatory properties of goji berries extract in human colon cancer cells
- Lycium barbarum polysaccharides induce apoptosis in human prostate cancer cells and inhibits prostate cancer growth
- Identification of goji berry cyclic peptides and anticervical carcinoma activity
- Antiproliferative effects of Lycium barbarum’s (goji berry) fractions on breast cancer Cell Lines
You get the idea: it helps!
Bonus benefit for the eyes
Goji berries also help against age-related macular degeneration. The research for this is in large part secondary, i.e. goji berries contain things x, y, and z, and then separate studies say that those things help against age-related macular degeneration.
We did find some goji-specific studies though! One of them was for our old friends the “Lacto-Wolfberry” people and again, wasn’t very transparent, so we’ll not take up extra time/space with that one here.
Instead, here’s a much clearer, transparent, and well-referenced study with no conflicts of interest, that found:
❝Overall, daily supplementation with Goji berry for 90d improves MPOD by increasing serum Z levels rather than serum L levels in early AMD patients. Goji berry may be an effective therapeutic intervention for preventing the progression of early AMD.❞
- MPOD = Macular Pigment Optical Density, a standard diagnostic tool for age-related macular degeneration
- AMD = Age-related Macular Degeneration
(that whole paper is very compelling reading, if you have time)

Where to get goji berries?
You can probably find them at your local health food store, if not the supermarket. However, if you’d like to buy them online, here’s an example product on Amazon for your convenience
