If you’re searching for a natural supplement that’s explicitly designed to support healthy blood pressure and boost daytime energy, you’ve probably seen a lot of products with big promises. I tested (and read into) Arteris Plus, a plant-based formula created by John Mayers that combines passion flower, marshmallow, corydalis, prickly pear and California poppy seed. Below I’ll walk you through what’s inside, what the research and traditional use say, who it might suit and why this supplement could be worth trying if you’re looking for a gentle, natural approach to cardiovascular wellness.

Quick verdict
Arteris Plus is a thoughtfully composed herbal capsule that leans on calming and circulation-supporting plants used in traditional medicine. It’s not a pharmaceutical—so don’t expect a magic cure—but if your goal is to support healthy blood pressure ranges while improving daytime energy and stress resilience, Arteris Plus is a clean, USA-made option that’s worth considering.
Who made Arteris Plus?
John Mayers (the product’s founder) says the formula grew out of a lifelong passion for plants and natural health. According to the product copy, ingredients are sourced from local growers, third-party purity checks were done and capsules are produced in a U.S. facility that’s FDA-registered and GMP-certified. The company also emphasizes non-GMO ingredients and no habit-forming stimulants. Those are positive manufacturer claims to look for when choosing any supplement.
What’s inside — ingredient deep dive
Below I break down the five headline ingredients and what we know about them from clinical studies, traditional use and safety summaries.
Passion Flower (Passiflora)
Passion flower is widely used as a mild anxiolytic and calming herb. Research suggests it may reduce stress and nervousness, which — indirectly — can help lower blood-pressure spikes caused by stress. Animal and human studies indicate calming effects and improvements in sleep/anxiety markers, although results vary between studies. These calming properties are why passion flower often appears in circulation-support blends that aim to keep blood pressure steady under stress.
Marshmallow (Althaea officinalis)
Marshmallow root is best known for its mucilage content — the soothing, protective film it creates on mucous membranes. That’s why it’s classically used for coughs and throat irritation, but it’s also valued as a gentle anti-inflammatory and demulcent in herbal medicine. Scientific reviews note traditional and modern uses, though human clinical data on blood-pressure effects are limited. In a formula like Arteris Plus, marshmallow likely contributes soothing and supportive properties rather than direct blood-pressure lowering effects.
Corydalis (Corydalis yanhusuo)
Corydalis is a traditional Chinese herb used for circulation and pain relief. Modern studies have identified active alkaloids (like tetrahydropalmatine) with analgesic and circulation-modulating effects; some preclinical research points to improved cardiac function and circulation markers. Corydalis can be useful in formulas aiming to support healthy blood flow, though it should be used with care and under advice if you take other medications.
Prickly Pear (Opuntia species)
Prickly pear (opuntia) — the edible cactus fruit/cladode — has been studied for metabolic and cardiometabolic benefits. Several trials and reviews show that prickly pear consumption can produce modest reductions in blood pressure and cholesterol in some populations, though studies are varied in size and methodology. As a natural antioxidant and fiber source, prickly pear is a logical inclusion for cardiovascular-support supplements.
California Poppy (Eschscholzia californica)
California poppy is traditionally used as a gentle sedative and anxiolytic. Lab and human data suggest it may promote relaxation and mild sedation (helpful for sleep and stress relief). European herbal authorities and recent reviews recognize its long-standing use for mild stress and sleep issues. In a blood-pressure support product, California poppy works synergistically with passion flower to reduce nervous tension that can drive temporary blood pressure elevations.
How Arteris Plus aims to work
Rather than targeting blood pressure with a single strong compound, Arteris Plus uses a multi-pronged, plant-synergy approach:
- Calm the nervous system: Passion flower + California poppy may reduce stress-related spikes in blood pressure by promoting relaxation and better sleep.
- Support circulation: Corydalis and prickly pear are included to help improve blood flow and metabolic markers that influence vascular health.
- Soothe and protect: Marshmallow adds a gentle, supportive role — calming inflammation and promoting tissue comfort.
This stacked, supportive strategy is common in botanical cardiovascular supplements: lower stress and improve circulation and you often see gentle improvements in blood-pressure stability over time.

Safety, purity & manufacturing
The product description stresses third-party testing, non-GMO ingredients and manufacture in a U.S. FDA-registered, GMP-certified facility. Those are important flags for quality — look for lot numbers, third-party lab reports (COAs) and ingredient sourcing details on the label or product page before buying.
A few safety notes to keep in mind:
- Some herbs (e.g., corydalis) can interact with prescription medications and may affect liver enzymes; talk to your doctor if you’re on blood thinners, heart medication, sedatives or other chronic drugs.
- Herbs with sedative action (passion flower, California poppy) can increase drowsiness, especially when combined with other sedatives.
- Always follow recommended dosages on the bottle and consult your physician if you have existing heart disease, are pregnant or breastfeeding.
Who should consider Arteris Plus?
Arteris Plus is geared toward adults who:
- Prefer natural, plant-based supplements.
- Want to support healthy blood-pressure ranges (not replace prescribed blood pressure meds).
- Struggle with stress, sleep disruption or low daytime energy tied to nervous tension.
- Are looking for a product manufactured in the U.S. with claims of third-party testing and GMP standards.
It’s not recommended as a substitute for prescription antihypertensive medication for anyone with diagnosed hypertension without medical supervision. If your blood pressure is consistently high, see your healthcare provider first.
My impression — strengths & limitations
Strengths
- Ingredient synergy: The calming + circulation combo is logical and evidence-backed at least in principle. Passion flower and California poppy help with stress; prickly pear and corydalis support circulation.
- Clean manufacturing claims: Third-party testing and GMP/FDA facility statements (if verified on the label) are reassuring.
- Non-habit forming blend: The formula avoids strong stimulants and claims to be non-habit forming, a big plus for long-term use.
Limitations
- Clinical proof for the exact product is likely limited: Most evidence is ingredient-level, not trials of Arteris Plus itself. That’s normal for many supplements, but it means personal results can vary.
- Interactions: People on meds or with chronic conditions should get a clinician’s OK before trying it.
How to use (general guidance)
Follow the manufacturer’s label for serving size. If you’re new to botanical blends, it’s smart to:
- Start with the lowest recommended dose to assess tolerance.
- Take consistently for several weeks — botanical benefits often build over time.
- Monitor your blood pressure at home if that’s your health goal and flag any unusual symptoms with your doctor.
Final thoughts — is Arteris Plus worth it?
If you want a natural, well-thought-out supplement with calming and circulation-focused herbs, Arteris Plus is a compelling option. It assembles herbs with history and supporting research into a convenient capsule and the U.S. manufacturing/quality claims are encouraging. While it shouldn’t replace medical care for diagnosed hypertension, it may be a gentle, supportive addition for adults seeking to keep blood pressure in a healthy range while improving stress resilience and energy.
If you value plant-based solutions, prioritize ingredient transparency and are comfortable checking with your healthcare provider when necessary, Arteris Plus is worth a close look.
