The Power of Maca

We are now almost at the end of our second trial week for the maca project (read about it here, and the first part of the maca diaries, here), and it is going very well. I think it’s time for me to give you a little more information about this amazing root.

What is it?

First of all, maca is a cruciferous root found growing in the high regions of Peru and has been cultivated for about two thousand years. It has been traditionally and is currently used as a food. The Peruvians believe it gives strength and endurance, enhances ones fertility, and supports pregnancies.

As maca has been put more in the spotlight in recent years, many studies have been done on it, everything from feeding farmed trout, to treating sexual problems (how’s that for a wide variety of uses!). As I have read about it, I realized that there are many, many different applications that maca could be used for. However, even though there are a lot of studies about maca, most of them center around certain topics, so there are still huge gaps of scientific information. This is frustrating because how I got interested in maca was it’s traditional use to support a pregnancy, and it’s claimed ability to balance hormones, and these two uses of maca have not been addressed at all, or at least, as thoroughly as some of the other uses.

So, for some of the uses, people are still relying on tradition and clinical results. Keep that in mind as you research maca yourself. But let me share what I have found out about maca.

Note Different Varieties of Maca

Before I started researching, I figured that maca was all one variety, but that is not true. In fact, there are at least three common types (yellow, red and black), and these different varieties do have slightly different results. In fact some of the studies actually compared the effect of more than one type, to see which one would be effective for a certain application. Because of that, when a study I site used a particular variety of maca, I will make sure to list it. If you are interested in maca for a certain use, make sure that you get the right type of maca.

Maca is a High Nutrient Root

First things first, maca is a high nutrient vegetable. It is full of calcium, magnesium, some b vitamins, vitamin c, as well as zinc and many other important minerals, protein and fiber. For a detailed list of what maca contains, I found that has thorough information.

You could consider maca a superfood from looking at how nutrient dense it is.

Maca could help prevent Osteoporosis caused by lack of estrogen

In fact, one study tested the ability of maca to reduce bone loss in estrogen deprived rats. The conclusion? It was ” indicated that higher dose of ethanol extract of Maca was effective in the prevention of estrogen deficient bone loss.”

Maca Supports Fertility

Unfortunately, infertility has become more and more of an issue for many of us. I think that overcoming infertility can and should be multifaceted. But as I have researched maca, I have wondered if maca could be helpful for many people dealing with infertility, especially if it was taken while making other healthy changes. Maca is unique in that is helps both men and women’s fertility.

Maca Increases Men’s Fertility

Maca was once thought to increase men’s sexual hormones which would account for it’s ability to increase one’s sex drive and increased fertility, but while recent studies confirm that maca has the powerful ability to increase male fertility, it doesn’t change men’s hormone levels. In one four month study using black maca, it was found to increase sperm count, motile sperm count and sperm motility and increase seminal volume, all without making any changes in the men’s hormones. I should mention that this was one study, among many, all showing similar results.

It was also shown that maca reversed infertility caused by lead poisoning in rats.

Maca Increases Women’s Fertility

In another study, they tested the traditional use of maca to increase women’s fertility, using mice. It seems mice also find maca helpful, as those receiving maca did indeed have increased fertility! This test used yellow maca.

I also found these threads on Mothering’s forum of a whole group of women using maca to try to achieve pregnancy. It was very interesting reading everyone’s results with it (and yes, there were a lot of pregnancies in the group!). Thread One, Thread Two Thread Three

Could Help Depression and Black Maca could Increase Learning and Memory Abilities

In one study, they studied the effect of the three different types of maca in decreasing depression and increasing learning abilities in mice. They found that all three had anti-depressant effects, but only black maca had the ability to increase learning and memory abilities. In a follow up study on black maca, they found that it helped improve scopolamine-induced memory impairment in mice.

Maca Could Help Prevent UV Skin Damage

Maca was found to have UV protection abilities. I wondered if this is because of the antioxidants in contains. In a Food Chemistry 1 article, although maca was found to have lower levels than green tea, they did find it to have the capacity to scavenge free radicals and protect cells from oxidative stress. Antioxidants are supposed to keep prevent skin damage as well.

Maca Could Help Glucose Control

Maca could be very useful for those struggling with blood sugar issues. Researchers found that maca “significantly” increased glucose tolerance and decreased blood sugar. I have personally found that maca seems to be helping me keep my blood sugar much more stable. This could be significant to those with diabetes or hypoglycemia.

Maca Helps Menopausal Women

In a study designed to examine the effects of maca on hormones and the symptoms of postmenopausal women, it was found that that maca didn’t change their hormonal balance at all! But that it did help significantly aid in the symptoms of menopause, including depression, sexual dysfunction, and anxiety.

There is not a lot of scientific studies (at least, that I have found) specifically studying the effect maca has on the hormonal balance of women. Clinical and personal observations claim that maca has proven helpful in this area, but it is yet to be proven scientifically. This study seems to support the idea that it doesn’t touch actual hormones, but instead works independently of them to relieve certain female issues.

This is one of the uses of maca that I personally hope researchers will put more research into. In fact, there ends most of the most helpful research I found. There are still a lot of traditional uses of maca that many people have found true for themselves, but are not yet studied.

But I would remiss if I didn’t mention one other well documented use of maca.

Maca Can Help With Sexual Problems (for both men and women)

Maca is used to treat certain sexual problems in both men and women with very good results. Feel free to research this if you, or a loved one, deals with this very personal issue. It could be very useful for you.

Here is a list of other important uses for maca:

Maca could help those with Thyroid and Adrenal problems or Chronic Fatigue

While I have not been able to find any official studies on the effect maca has on thyroid health, it doesn’t take long to find testimonies of those helped by maca in this area. I have personally found that I do seem warmer while taking maca (temperature control is related to thyroid function) and I do have better energy (adrenal). For further reading, here are just a few links for you.

Dr. Muller answer Questions about Maca

A forum discussion about maca and thyroid function

Article on Maca

While reading about about maca, since there are no hard facts about how it works, some doctors consider it an adrenal stimulate (and therefore not the best choice), and others don’t think that it’s the best for some thyroid conditions. Others think it’s the best choice available, so do your own homework before using. It seems to be working for me, but that’s just my personal experinece.

Maca Can Give Endurance and Energy

One of the traditional uses of maca is for energy and endurance, for that reason some athletes are now using maca with good results. But who needs to be an athlete to want more energy and endurance!

Maca can help with PMS and other hormonal issues

While the “why” of how maca works in this area has not been answered for me, many people find maca to be very helpful in these areas.

Like I mentioned before, Maca was traditionally used not only to help one get pregnant, but to stay pregnant as well. This has not been tested for safety or effectiveness, but is a traditional use of it.

While there are many other claimed uses for maca, I think that covers most of the main points. As I read more and hopefully find more information, I will do updates.

Who Shouldn’t Take it?

While maca is not considered to be toxic, because of the lack of information, different sites did caution against using maca if you have a high risk of breast or prostate cancer. This was probably because it is still widely thought of as increasing certain hormones (which could be bad for certain cancers), which recent research doesn’t seem to back. But do take note.

Those with a high risk of goiters should also be careful, though there have been no reported cases.

Those pregnant or nursing are not officially advised to take maca from any company because it is not tested yet.

Some advise those with a hyperthyroidism not to take it.

In one study, those taking a large amount of maca every day, did have slight elevations of blood pressure. Keep this in mind if you have blood pressure issues.

If you are interested in taking maca, I encourage you to do your own research and talk it over with a qualified health care provider (some love it, some aren’t so sure about it). Maca appears like it could indeed be helpful for many, and while it is, after all a FOOD in Peru, it doesn’t hurt to err in caution.

    Hi, Kimi,

    I’m glad you are writing about this. I’ve been writing about it, too, on my blog.

    I started on maca a couple of months ago. I only take about 1/2 tsp per day.

    Within the first month I was astounded to find that ALL my PMS symptoms had pretty much disappeared.

    I have always had very bad menstrual cramps. I have always had to take Tylenol or ibuprofren. For the first time ever, I didn’t have to take anything.

    I still felt cramps but they were so light and so minor that it really didn’t bother me. Certainly not enough to have to take anything.

    The second month was the same — virtually no PMS and barely noticable cramps.

    The other thing that is happening for me is my average temperature is going up — which is a good thing because it’s been chronically low (I have adrenal fatigue).

    I’ll be curious to see how you continue to benefit from it.

      My wife and I have had unprotected sex for 3 years. Two months ago we both started taking Maca daily , two tablespoons with our oatmal 6 days week. Bada Bing Bada Boom today she is pregnant!!! Whoopee!!

      Hi All (and especially Ann Marie & Michelle),

      I am now on the second day of my period, after starting on gelatinized red maca root powder two weeks ago (about three tsps a day, broken up into two doses). Usually my second day is when I start to get bad cramps and at the very first twinge I have to quickly take a dose of ibuprofen or naproxen (I even usually start naproxen a day or so ahead) or I am in big trouble!! Today I decided to go ahead and let the twinge happen and go cold turkey on the meds to see if this maca powder will do the trick… so far so good.

      I was put on The Pill at the age of thirteen to combat my cramps and heavy flow because they were so bad. I am now 37, and I have been off The Pill for almost ten years and there has been no difference to my horrific experience! Fish oil helped for a while, just a little, and I have had to bounce between ibuprofen and naproxen over the years when they stopped being effective. I stick strictly to recommended dosages, but for the past year neither seems to be effective. A little toke has also been effective, but that stopped helping last year. I even went through a period where heating my abdomen (Sir Algernon Bottleworth – my hot water bottle – has always been my saviour) stopped working for about four months!!

      I will check back in later, and let you know how it went. Thank you both, Ann Marie and Michelle, for writing about this. Surprisingly, I wasn’t able to find too much on this particular subject, and dysmenorrhea has been a staple issue in my life for almost a quarter century!

      Thank you Kimi for this forum,

    • Jennifer says

      May I have your blog site? I too suffered from adrenal fatigue and severe pms. I just purchased root powder and it’s exciting to know it worked for you. So you take 1/2 tsp daily, not just before period time? Thanks!!

  2. 1210164830s29262 says

    Kimi – I just wanted to say thanks for inspiring me to give maca another try!

    I’ve discovered that it actually tastes ok in a hot chocolate type drink.

    I mix the maca with some carob powder (not cocoa as its too stimulating for the adrenals) next add some boiling water to dissolve the maca and carob and then top up with boiling coconut milk and finally sweeten with agave and vanilla. It’s got a slightly gritty texture but it’s the best way I’ve found so far!!

  3. Alison @ Wholesome Goodness says

    This is so interesting. I’m definitely asking my naturopath about when I see him next week. I wonder if he has any experience with it. I’ve seen a lot of hormonal improvements, but I’m not all the way there yet. I’m curious to find out if maca might help me.

  4. Sarah says

    I can’t wait to see your results! I just took my temp (we have a couple sick in the house) and it’s 97.4. That seems a little low and seeing as I always feel cold, maybe that’s why. So I looking forward to hearing which you recommend. I also have problems getting pregnant so maybe it will help with that too.

  5. My Year Without says

    I am so curious about this…

    I appreciate the extensive list you compiled of the benefits of Maca, and your open-mindedness about it, too.

    I am definitely going to look into this further.

  6. Brenda says

    Just started taking a tsp a day after seeing a report on Dr Oz for low libido and discovered all the other benefits…used in it my cereal with almond milk..couldn’t tell it was there..also made a has a malty flavor so will try a shake..looking foward to its benefits

  7. michelle says

    I am in my second month of taking Maca I take it in pill form. I must say that the main reason I began to take it is because I had a miscarriage in August and was researching for fertility vitamins and ways to maintain a pregnancy when I came across this website I have notice this month that I really thought I was going to get my BFP because I had no PMS symptoms no cramps no sore breast no mood swings. I am usually in a ball for about a week 3 days before my period and 3 or 4 days at the start because of such painful cramps. I will continue to take Maca for the rest of my life. And will continue to take it if it will help me to make sure my little bean sticks when I finally get pregnant.

    I was introduced to the powder by a neighbour whilst discussing “hot flashes” which
    as you know go with menopause – I have only been taking it for a week and….. hot
    flashes GONE!! Try it, it is great

  9. says

    I truly believe that maca played a huge part in my getting pregnant at ages 39 and 41 after having 2 miscarriages before that. It is know for helping improve egg quality, which is very beneficial for women over 35 trying to conceive. It is also an energy and libido booster!

  10. Anna says

    Hi Ladies,

    Could you tell me what brands you are using. I know there is a difference between the gelatinized and non-gelatinized versions. Wondering what is working well for you ladies.

    I had intense hot flashes and tried black cohosh and evening primrose with no obvious results. I started taking red maca in a morning smoothy and voila! Minimal to no more hot flashes and greatly improved sleep 🙂

    • says

      Is it safe to take maca? I was just wondering. I suffered with intense hot flashes, can’t sleep at night. I so tired all the time. I would like to take something that is natural insead of prescription stuff.

    Thanks for the interesting post. My experience with maca root supplements is very positive. I was in a stage that i was constantly tired and in bad mood(depressed). Couldn’t get up from the bed in the morning. I heard about maca properties and decided to try it. Started with daily dose of 500mg of raw maca powder, but it had bad effect on my stomach. I changed it to Gelatinized form of maca( i took organic gelatinized capsules) and after a while felt some improvement. I increased my daily dose to 1000mg and after 2 month I had energies that i couldn’t believe! Now it’s been 8 months and I’m still taking maca as a part of my daily diet and very happy with my high energies.
    Try quality maca products and their reviews at my friend’s website

  15. ANNA says

    I have no thyroid due to thyroid cancer. Can Maca contribute to it coming back? I have been taking it for a month and love it. But I want to be sure it is safe for someone with no thyroid due to cancer.
