Supplements with maca root are often formulated alongside herbs like ashwagandha, fenugreek, and beet root, each studied separately for different reasons. Most haven’t been tested together in a single clinical trial, so here’s what research shows about each herb on its own, and why formulators pair them with maca.
Maca Root and Ashwagandha: What the Research Shows
Ashwagandha is one of the most commonly paired herbs with maca root. Research on ashwagandha alone has looked at a few areas:
- A randomized, placebo-controlled study found adults taking a standardized ashwagandha extract (600 mg/day) for 8 weeks reported lower stress and anxiety scores versus placebo (Chandrasekhar et al., 2012, PubMed)
- A separate study in healthy men paired ashwagandha with resistance training over 8 weeks and reported greater increases in muscle strength and recovery versus placebo (Wankhede et al., 2015, PubMed)
These studies looked at ashwagandha on its own, not combined with maca, so any effect from taking both together hasn’t been directly studied. Formulators typically pair the two because maca is researched mainly for sexual health and energy, while ashwagandha leans toward stress and recovery — different areas rather than duplicating the same one. If energy and performance are your main goal, this guide on best maca root supplements for men looks at that angle specifically.
Maca Root and Fenugreek: What the Research Shows
Fenugreek is another herb frequently combined with maca root, largely from a small set of studies on male reproductive health:
- One study found men taking standardized fenugreek extract for 6 weeks reported changes in self-reported libido and vitality versus placebo (Steels et al., 2011, PubMed)
- Another small trial in men doing resistance training observed changes in body composition and hormone markers after 8 weeks of fenugreek supplementation (Wankhede et al., 2016, PubMed)
Both studies were small, and the researchers involved noted the need for larger trials before drawing firm conclusions. As with Ashwagandha, fenugreek hasn’t been studied in direct combination with maca root.
Maca Root and Beet Root: What Studies Have Found
Beet root shows up in maca blends mostly because of research on nitrate content and blood flow:
- A study on dietary nitrate from beetroot juice found improvements in cycling time-trial performance in trained athletes (Lansley et al., 2011, PubMed)
- A meta-analysis of multiple trials found beetroot and inorganic nitrate supplementation was linked to modest reductions in blood pressure (Siervo et al., 2013, PubMed)
The reasoning behind pairing beet root with maca is generally about supporting blood flow and stamina alongside maca’s studied effects on energy and sexual health — though again, this specific combination hasn’t been tested as a stack.
What About L-Arginine?
L-arginine is sometimes added to maca blends (as in stacks like maca root, ashwagandha, fenugreek, beet root, and L-arginine) since it’s a building block the body uses to produce nitric oxide, similar to beetroot. Research on L-arginine’s effects on blood flow and exercise is mixed — some studies show modest benefits, others none — so treat it as early, inconsistent evidence.
Does Maca Root Capsule Form Matter?
Maca is sold as raw powder, gelatinized powder, and capsules. Most clinical studies referenced across maca research used powder or standardized extract doses measured in milligrams, not a specific capsule brand or format. There isn’t strong direct research comparing absorption between capsule and powder forms of maca. In practice, capsules are often chosen for convenience and consistent dosing rather than a proven absorption advantage. This comparison of best maca root supplements: powder vs capsules breaks down the practical differences in more detail.
Why Are These Ingredients Combined at All?
There isn’t direct research testing maca, ashwagandha, fenugreek, and beet root together as a single formula. The reasoning behind these stacks comes down to combining herbs studied in different, complementary areas:
- Maca: sexual health, energy, semen quality
- Ashwagandha: stress response, muscle recovery
- Fenugreek: libido, body composition markers
- Beet root / L-arginine: blood flow, exercise performance
This is a formulation rationale based on each ingredient’s individual research, not evidence the combination produces a bigger effect than the ingredients alone. Maca itself also comes in different varieties — this guide on black maca root supplement explains how it differs from red and yellow maca, and the best maca root supplement for women covers women’s-specific formulas.
Are These Combinations Safe?
Individually, these herbs were generally well tolerated in the studies referenced above, with few reported side effects. A few things worth keeping in mind:
- Combining multiple active herbs increases the total number of compounds you’re taking, so it’s worth reviewing each one
- People on medication, particularly for blood pressure, blood sugar, or hormone-related conditions, should talk to a doctor first
- Results in these studies generally built up gradually, not overnight — this maca root supplement benefits timeline breaks down what tends to show up at 7, 30, and 90 days
- For more detail on maca specifically, this guide on maca root supplement side effects is a useful starting point
The Bottom Line
Supplements with maca root are often paired with ashwagandha, fenugreek, or beet root since each ingredient has its own separate research base, not because the combination itself has been directly studied. Circle of Nature’s Maca Root & Ashwagandha Root Extract Capsules take this pairing approach, combining:
- 500 mg Maca Root Extract, standardized to 5% macamides
- 600 mg Ashwagandha Root Extract (10:1 concentration)
- 40 mg Turmeric Extract, standardized to 95% curcuminoids
- 5 mg BioPerine (Black Pepper Extract), standardized to 95% piperine, included to support absorption
The formula is made in the USA under GMP standards, and free of common fillers, gluten, soy, dairy, and artificial colors or preservatives. As with any supplement, it’s worth checking standardized extract percentages and dosing against the research amounts discussed above.
FAQs
Is it better to take maca root with other supplements?
Some people prefer combination formulas since each herb is studied in a different area, such as stress, libido, or blood flow. There’s limited direct research on combining them, so this is more of a formulation choice than proven synergy.
What is the most researched combination with maca root?
Maca and ashwagandha are commonly paired since ashwagandha has one of the larger research bases among adaptogenic herbs, though the two haven’t been studied together directly.
Are maca root capsules better than powder?
Not necessarily. Most clinical research used measured doses of powder or extract, not a specific capsule format. Capsules are mainly chosen for convenience and consistent dosing.
