Maca (Lepidium meyenii) is an Andean root vegetable that has been used traditionally in Peru for centuries. In recent years, it has attracted research interest for its potential role in supporting women during perimenopause — particularly around symptoms like hot flashes, energy, mood, and libido. The research is promising but still limited, and maca is best understood as a nourishing whole food rather than a treatment.
What is maca and how is it thought to work?
Unlike some herbs, maca is not thought to directly supply hormones or act as a phytoestrogen. Instead, it contains unique compounds called macamides and macaenes that some researchers believe may support the body's own hormonal regulation systems, including the hypothalamic-pituitary-adrenal (HPA) axis. This is why maca is sometimes classified as an adaptogen — a term used for plants thought to support the body's resilience to stress and hormonal fluctuation.
What has research explored about maca and perimenopause?
A number of small clinical studies have looked at maca in perimenopausal and postmenopausal women. Some studies have found associations between maca supplementation and self-reported improvements in hot flash frequency, mood, energy, and sexual function. However, it's important to note that most studies have been small, short in duration, and not always well-controlled. Larger, more rigorous trials are needed before firm conclusions can be drawn.
Does maca affect hormone levels directly?
Some studies have found that maca did not significantly alter blood levels of estrogen, progesterone, or FSH — suggesting its effects, if any, may be mediated through mechanisms other than direct hormonal action. This may be relevant for women who are cautious about phytoestrogens or hormone-sensitive conditions, though it's always worth discussing with your doctor.
What are the different types of maca?
Maca comes in several varieties — yellow, red, and black — which may have slightly different nutritional profiles. Yellow maca is the most commonly studied in relation to women's hormonal health. Gelatinized maca (which has been heat-treated) is often easier to digest than raw maca powder for people with sensitive stomachs.
How is maca typically consumed?
Maca powder is commonly added to smoothies, oatmeal, or drinks. A typical amount used in research studies ranges from 1.5 to 3 grams per day, though these amounts are not standardized recommendations. It has a slightly earthy, nutty flavor that blends well with cacao and other warming flavors.
Neeshi's Nourishing Protein Blend includes maca as one of its functional ingredients, alongside flaxseed, chia, and gooseberry, making it easy to incorporate into a daily smoothie or breakfast routine.
Are there any cautions with maca?
Maca is generally considered safe as a food for most people. Women with thyroid conditions should be aware that raw maca contains goitrogens — compounds that can affect thyroid function in large amounts. Cooking or gelatinizing maca reduces goitrogen content. Women with hormone-sensitive conditions or those on medication should consult their healthcare provider before using maca regularly.
Frequently Asked Questions
How long does it take for maca to have any effect?
Studies that have observed effects typically ran for 6–16 weeks. Like most food-based approaches, maca is not an overnight solution and consistent use over time appears to be important.
Can maca be taken alongside HRT?
There is limited research on maca in combination with HRT. If you are on hormone therapy, discuss any new supplements or foods you're adding with your healthcare provider.
Is maca suitable for women who are still menstruating?
Maca has been studied primarily in peri- and postmenopausal women, but it is also consumed widely as a general nutritional food. Women with regular cycles who are curious about maca should discuss it with their doctor, particularly if they have hormone-sensitive conditions.
