Hack Your Sex Drive With Maca
By: Bulletproof Staff
Maca is an interesting little root. The Peruvian plant only grows in the most inhospitable parts of the Andes, yet it’s becoming popular worldwide as an aphrodisiac and fertility booster. It also has a decent nutritional profile, and its mild, earthy taste means it pairs nicely with chocolate and disappears into smoothies. There’s been a decent amount of research on maca for sex drive and libido, with interesting results. Here’s a closer look at what maca root does, along with a few thoughts on when and how to eat it.
Maca may boost sex drive…we’re just not sure why
Unlike powdered rhinoceros horn, dried tiger penis, and most other traditional aphrodisiacs, maca actually seems to work. There’s some evidence to back up claims of its sex-enhancing properties.
In a double-blind 2002 study, researchers gave 57 men either 1.5g maca, 3g maca, or placebo. The men received the supplements daily for 12 weeks. After 8 weeks, men in the two maca groups reported heightened sexual desire .
Another study looked at 20 depressed men on SSRIs – antidepressants that often decrease sex drive – and found that 3g of maca daily significantly increased self-reported libido, although 1.5g of maca did not . A similar study looking at 45 women on antidepressants found maca had the same effect .
A fourth study of 8 endurance athletes found that maca extract (the equivalent of 10g/day maca) increased self-reported sexual desire (though it did not improve endurance training) .
These studies were small and they relied on self-reporting. That said, they were also all double-blind, placebo-controlled, and randomized, and each one showed the same pattern of results: maca increased libido. Add in a 2001 study showing that both 1.5g and 3g of daily maca increased sperm count and sperm motility , plus another one showing that it improved erectile dysfunction , and it seems like there may be something to the claim that maca is an aphrodisiac.
What makes maca so interesting is that we still don’t understand why it increases sex drive. Sex drive usually links to sex hormones, though with maca that doesn’t seem to be the case. Researchers have measured testosterone and estrogen levels of people taking maca and found no changes , even when the participants reported increased libido.
Maca gets moldy
Traditionally, Peruvians dry maca root and crush it into a powder. Dried maca powder is what you’ll typically find in health food stores as well. The trouble is that maca often grows mold during the drying process, and the resulting powder often contains aflatoxin, a potent carcinogen. Maca was on the drawing board as a Bulletproof product for a while, but it was difficult to find a pure source; even the highest quality maca root contained about 13 ppb aflatoxin. That’s not up to Bulletproof standards.
If you buy maca, get it from a high-end brand, and if you take it and you feel sick or foggy afterward, consider that your discomfort could be due to a moldy batch and not maca root itself. Buying whole maca root and soaking it overnight could help get rid of some of the mold toxins.
Always cook your maca
While maca looks and tastes like a root, it’s actually a cruciferous vegetable, along with cauliflower, kale, cabbage, Brussels sprouts, and other members of the Brassica family. And like other cruciferous veggies, maca contains goitrogens, anti-nutrients that disrupt thyroid hormones. While goitrogens are bad news, they don’t stand up to heat well. That means you should always cook your maca (and your cauliflower, kale, cabbage, etc.). If you find maca root whole, you can bake or boil it and then make it into a mash, the way you would prepare potatoes. If you buy powdered maca, skip the raw variety and instead go for for gelatinized maca. Despite its name, gelatinized maca isn’t gelatinous. It’s still a powder, and it will still mix into most dishes well; the gelatinization process just removes antinutrients, proteins, and starches. It seems to leave maca’s aphrodisiac properties intact.
Maca is a good source of vitamin C, iron, potassium, and copper, and it has a decent amount of B vitamins. Maca comes in several shades, and the darker roots are high in tough-to-find iodine. Maca has a malty, nutty, slightly sweet flavor that pairs well with chocolate and vanilla, so it’s a great addition to smoothies or protein shakes. You could even spoon some into your morning coffee, although the high starch content may take you out of ketosis. However you take it, be sure your maca’s cooked, and get the high-quality stuff to avoid mold toxins as much as possible.
