I’m iron deficient. Which supplements will work best for me and how should I take them?

Iron deficiency is common and can be debilitating. It mainly affects women. One in three premenopausal women are low in iron compared to just 5% of Australian men. Iron deficiency particularly affects teenage girls, women who do a lot of exercise and those who are pregnant.
The body needs iron to make new red blood cells, and to support energy production, the immune system and cognitive function. If you’re low, you may experience a range of symptoms including fatigue, weakness, shortness of breath, headache, irregular heartbeat and reduced concentration.
If a blood test shows you’re iron deficient, your doctor may recommend you start taking an oral iron supplement. But should you take a tablet or a liquid? With food or not? And when is the best time of day?
Here are some tips to help you work out how, when and what iron supplement to take.
How do I pick the right iron supplement?
The iron in your body is called “elemental iron”. Choosing the right oral supplement and dose will depend on how much elemental iron it has – your doctor will advise exactly how much you need.
The sweet spot is between 60-120 mg of elemental iron. Any less and the supplement won’t be effective in topping up your iron levels. Any higher and you risk gastrointestinal symptoms such as diarrhoea, cramping and stomach pain.
In Australia, iron salts are the most common oral supplements because they are cheap, effective and come in different delivery methods (tablets, capsules, liquid formulas). The iron salts you are most likely to find in your local chemist are ferrous sulfate (~20% elemental iron), ferrous gluconate (~12%) and ferrous fumarate (~33%).
These formulations all work similarly, so your choice should come down to dose and cost.
Many multivitamins may look like an iron supplement, but it’s important to note they usually have too little iron – usually less than 20 mg – to correct an iron deficiency.
Should I take tablets or liquid formulas?
Iron contained within a tablet is just as well absorbed as iron found in a liquid supplement. Choosing the right one usually comes down to personal preference.
The main difference is that liquid formulas tend to contain less iron than tablets. That means you might need to take more of the product to get the right dose, so using a liquid supplement could work out to be more expensive in the long term.
What should I eat with my iron supplement?
Research has shown you will absorb more of the iron in your supplement if you take it on an empty stomach. But this can cause more gastrointestinal issues, so might not be practical for everyone.
If you do take your supplement with meals, it’s important to think about what types of food will boost – rather than limit – iron absorption. For example, taking the supplement alongside vitamin C improves your body’s ability to absorb it.
Some supplements already contain vitamin C. Otherwise you could take the supplement along with a glass of orange juice, or other vitamin C-rich foods.
On the other hand, tea, coffee and calcium all decrease the body’s ability to absorb iron. So you should try to limit these close to the time you take your supplement.
Should I take my supplement in the morning or evening?
The best time of day to take your supplement is in the morning. The body can absorb significantly more iron earlier in the day, when concentrations of hepcidin (the main hormone that regulates iron) are at their lowest.
Exercise also affects the hormone that regulates iron. That means taking your iron supplement after exercising can limit your ability to absorb it. Taking your supplement in the hours following exercise will mean significantly poorer absorption, especially if you take it between two and five hours after you stop.
Our research has shown if you exercise every day, the best time to take your supplement is in the morning before training, or immediately after (within 30 minutes).
My supplements are upsetting my stomach. What should I do?
If you experience gastrointestinal side effects such as diarrhoea or cramps when you take iron supplements, you may want to consider taking your supplement every second day, rather than daily.
Taking a supplement every day is still the fastest way to restore your iron levels. But a recent study has shown taking the same total dose can be just as effective when it’s taken on alternate days. For example, taking a supplement every day for three months works as well as every second day for six months. This results in fewer side effects.
Oral iron supplements can be a cheap and easy way to correct an iron deficiency. But ensuring you are taking the right product, under the right conditions, is crucial for their success.
It’s also important to check your iron levels prior to commencing iron supplementation and do so only under medical advice. In large amounts, iron can be toxic, so you don’t want to be consuming additional iron if your body doesn’t need it.
If you think you may be low on iron, talk to your GP to find out your best options.

Yoga Nidra Made Easy – by Dr. Uma Dinsmore-Tuli and Nirlipta Tuli
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’ve reviewed books about yoga before, and about sleep. This one’s different.
It’s about a yogic practice that can be used to promote restful sleep—or just be a non-sleeping exercise that nonetheless promotes relaxation and recuperation.
While yoga nidra is as somatic as it is psychological, its corporeal aspects are all explored in a lying-down-on-one’s-back state. This isn’t a book of stretches and poses and such—those are great, but are simply not needed for this practice.
The authors explain, step-by-step, simply and clearly, how to practice yoga nidra, and get out of it what you want to (there are an assortment of possible outcomes, per your preference; there are options to choose along the way).
A lot of books about yoga, even when written in English, contain a lot of Sanskrit terms. This one doesn’t. And, that difference goes a long way to living up to the title of making this easy, for those of us who regrettably don’t read even transliterated Sanskrit.
Bottom line: if ever you struggle to relax, struggle to sleep, or struggle to find your get-up-and-go, this book provides all you need to engage in this very restorative practice!

Cold Weather Health Risks
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.
Many Are Cold; Few Are Frozen
Many of those of us in the Northern Hemisphere are getting hit with a cold spell around now. How severe that may be depends on more precisely where we are, but it’s affecting a lot of people. So, with apologies to our readers in Australia, we’re going to do a special on that today.
Acute cold is, for most people, good for the health:
A Cold Shower A Day Keeps The Doctor Away?
Persistent cold, not so much. Let’s look at the risks, and what can be done about them…
Hypothermia
It kills. Don’t let it kill you or your loved ones.
And, this is really important: it doesn’t care whether you’re on a mountain or not.
In other words: a lot of people understand (correctly!) that hypothermia is a big risk to hikers, climbers, and the like. But if the heating goes out in your house and the temperature drops for long enough before the heating is fixed, you can get hypothermia there too just the same if you’re not careful.
How cold is too cold? It doesn’t even have to be sub-zero. According to the CDC, temperatures of 4℃ (40℉) can be low enough to cause hypothermia if other factors combine:
CDC | Prevent Hypothermia & Frostbite ← you can also see the list of symptoms to watch out for, there!
Skin health
Not generally an existential risk, but we may as well stay healthy as not!
Cold air often means dry air, so use a moisturizer with an oil base (if you don’t care for fancy beauty products, ordinary coconut oil is top-tier).
Bonus if you do it after a warming bath/shower!
Heart health
Cold has a vasconstricting effect; that is to say, it causes the body’s vasculature to shrink, increasing localized blood pressure. If it’s a cold shower as above, that can be very invigorating. If it’s a week of sub-zero temperatures, it can become a problem.
❝Shoveling a little snow off your sidewalk may not seem like hard work. However, […] combined with the fact that the exposure to cold air can constrict blood vessels throughout the body, you’re asking your heart to do a lot more work in conditions that are diminishing the heart’s ability to function at its best.❞
Source: Snow shoveling, cold temperatures combine for perfect storm of heart health hazards
If you have a heart condition, please do not shovel snow. Let someone else do it, or stay put.
And if you are normally able to exercise safely? Unless you’re sure your heart is in good order, exercising in the warmth, not the cold, seems to be the best bet.

Immune health
We recently discussed how cold weather indirectly increases the risk of respiratory viral infection:
The Cold Truth About Respiratory Infections
So, now’s the time to be extra on-guard about that.

Balance
Icy weather increases the risk of falling. If you think “having a fall” is something that happens to other/older people, please remember that there’s a first time for everything. Some tips:
- Walk across icy patches with small steps in a flat-footed fashion like a penguin.
- It may not be glamorous, but neither is going A-over-T and breaking (or even just spraining) things.
- Use a handrail if available, even if you don’t think you need to.

Red Lentils vs Green Lentils – 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 red lentils to green lentils, we picked the green.
Why?
Yes, they’re both great. But there are some clear distinctions!
First, know: red lentils are, secretly, hulled brown lentils. Brown lentils are similar to green lentils, just a little less popular and with (very) slightly lower nutritional values, as a rule.
By hulling the lentils, the first thing that needs mentioning is that they lose some of their fiber, since this is what was removed. While we’re talking macros, this does mean that red lentils have proportionally more protein, because of the fiber weight lost. However, because green lentils are still a good source of protein, we think the fat that green lentils have much more fiber is a point in their favor.
In terms of micronutrients, they’re quite similar in vitamins (mostly B-vitamins, of which, mostly folate / vitamin B9), and when it comes to minerals, they’re similarly good sources of iron, but green lentils contain more magnesium and potassium.
Green lentils also contain more antixoidants.
All in all, they both continue to be very respectable parts of anyone’s diet—but in a head-to-head, green lentils do come out on top (unless you want to prioritize slightly higher protein above everything else, in which case, red).

What Teas To Drink Before Bed (By Science!)
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.
Which Sleepy Tea?
Herbal “tea” preparations (henceforth we will write it without the quotation marks, although these are not true teas) are popular for winding down at the end of a long day ready for a relaxing sleep.
Today we’ll look at the science for them! We’ll be brief for each, because we’ve selected five and have only so much room, but here goes:
Camomile
Simply put, it works and has plenty of good science for it. Here’s just one example:
❝Noteworthy, our meta-analysis showed a significant improvement in sleep quality after chamomile administration❞
Also this writer’s favourite relaxation drink!
(example on Amazon if you want some)
Lavender
We didn’t find robust science for its popularly-claimed sedative properties, but it does appear to be anxiolytic, and anxiety gets in the way of sleep, so while lavender may not be a sedative, it may calm a racing mind all the same, thus facilitating better sleep:
(example on Amazon if you want some)
Magnolia
Animal study for the mechanism:
Human study for “it is observed to help humans sleep better”:
As you can see from the title, its sedative properties weren’t the point of the study, but if you click through to read it, you can see that they found (and recorded) this benefit anyway
(example on Amazon if you want some)
Passionflower
There’s not a lot of evidence for this one, but there is some. Here’s a small study (n=41) that found:
❝Of six sleep-diary measures analysed, sleep quality showed a significantly better rating for passionflower compared with placebo (t(40) = 2.70, p < 0.01). These initial findings suggest that the consumption of a low dose of Passiflora incarnata, in the form of tea, yields short-term subjective sleep benefits for healthy adults with mild fluctuations in sleep quality.❞
So, that’s not exactly a huge body of evidence, but it is promising.
(example on Amazon if you want some)
Valerian
We’ll be honest, the science for this one is sloppy. It’s very rare to find Valerian tested by itself (or sold by itself; we had to dig a bit to find one for the Amazon link below), and that skews the results of science and renders any conclusions questionable.
And the studies that were done? Dubious methods, and inconclusive results:
Nevertheless, if you want to try it for yourself, you can do a case study (i.e., n=1 sample) if not a randomized controlled trial, and let us know how it goes 🙂
(example on Amazon if you want some)
Summary
- Valerian we really don’t have the science to say anything about it
- Passionflower has some nascent science for it, but not much
- Lavender is probably not soporific, but it is anxiolytic
- Magnolia almost certainly helps, but isn’t nearly so well-backed as…
- Camomile comes out on top, easily—by both sheer weight of evidence, and by clear conclusive uncontroversial results.
Enjoy!

Easy Ways To Fix Brittle, Dry, Wiry Hair
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. Sam Ellis, a dermatologist, specializes in skin, hair, and nail care—and she’s here with professional knowledge:
Tackling the problem at the root
As we age, hair becomes less shiny, more brittle, coarse, wiry, or gray. More concerningly for many, hair thinning and shedding increases due to shortened growth phases and hormonal changes.
The first set of symptoms there are largely because sebum production decreases, leading to dry hair. It’s worth bearing in mind though, that factors like UV radiation, smoking, stress, and genetics contribute to hair aging too. So while we can’t do much about genetics, the modifiable factors are worth addressing.
Menopause and the corresponding “andropause” impact hair health, and hormonal shifts, not just aging, drive many hair changes. Which is good to know, because it means that HRT (mostly: topping up estrogen or testosterone as appropriate) can make a big difference. Additionally, topical/oral minoxidil and DHT blockers (such as finasteride or dutasteride) can boost hair density. These things come with caveats though, so do research any possible treatment plan before embarking on it, to be sure you are comfortable with all aspects of it—including that if you use minoxidil, while on the one hand it indeed works wonders, on the other hand, you’ll then have to keep using minoxidil for the rest of your life or your hair will fall out when you stop. So, that’s a commitment to be thought through before beginning.
Nutritional deficiencies (iron, zinc, vitamin D) and insufficient protein intake hinder hair growth, so ensure proper nutrition, with sufficient protein and micronutrients.
While we’re on the topic of “from the inside” things: take care to manage stress healthily, as stress negatively affects hair health.
Now, as for “from the outside”…
Dr. Ellis recommends moisturizing shampoos/conditioners; Virtue and Dove brands she mentions positively. She also recommends bond repair products (such as K18 and Olaplex) that restore hair integrity, and heat protectants (she recommends: Unite 7 Seconds) as well as hair oils in general that improve hair condition.

DVT Risk Management Beyond The Socks

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 know I am at higher risk of DVT after having hip surgery, any advice beside compression stockings?❞
First of all, a swift and easy recovery to you!
Surgery indeed increases the risk of deep vein thrombosis (henceforth: DVT), and hip or knee surgery especially so, for obvious reasons.
There are other risk factors you can’t control, like genetics (family history of DVT as an indicator) and age, but there are some that you can, including:
- smoking (so, ideally don’t; do speak to your doctor before quitting though, in case withdrawal might be temporarily worse for you than smoking)
- obesity (so, losing weight is good if overweight, but if this is going to happen, it’ll mostly happen in the kitchen not the gym, which may be a relief as you’re probably not the very most up for exercise at present)
- See also: Lose Weight, But Healthily
- sedentariness (so, while you’re probably not running marathons right now, please do try to keep moving, even if only gently)
Beyond that, yes compression socks, but also frequent gentle massage can help a lot to avoid clots forming.
Also, no surprises, a healthy diet will help, especially one that’s good for general heart health. Check out for example the Mediterranean DASH diet:
Four Ways To Upgrade The Mediterranean Diet
Also, obviously, speak with your doctor/pharmacist if you haven’t already about possible medications, including checking whether any of your current medications increase the risk and could be swapped for something that doesn’t.
Take care!
