Calroy Health Sciences Arterosil HP
Developed by Calroy Health Sciences, the Arterosil HP supplement was developed to support the endothelial glycocalyx (the layer of protection lining the vascular system) through scientifically validated research for its key ingredient (a proprietary seaweed extract that supports vascular health).
Arterosil HP is made from MonitumRS, an extract from a rare type of green seaweed called Monostroma nitidum, which is a sulfated polysaccharide, a specialized soluble fiber, and is mixed with various extracts of fruits, vegetables, and green tea to deliver antioxidant benefits. This vegan product addresses the Endothelial Glycocalyx (EGX), a gel-like structure that exists within blood vessels, regulates the movement of molecules across the blood vessel walls, produces nitric oxide, and ultimately protects blood vessels.
Studies have shown that ‘Rhamnan Sulfate’ is effective in maintaining and repairing the structure of the EGX when helping to ensure normal circulation, healthy arteries, and a strong heart. Each bottle of Arterosil HP contains 60 capsules and a one-month supply based on taking two capsules per day.
What Makes Arterosil HP Stand Out
Four pillars that separate Arterosil HP from conventional cardiovascular supplements.
Clinically Researched Ingredient:
Arterosil HP is the only vascular supplement designed to support the endothelial glycocalyx (EGX) through a unique patented full-spectrum rhamnan sulfate, “MonitumRS,” developed at institutions such as Drexel University through more than 25 years of research.
Vascular Support Benefits:
Animals and in vitro studies have shown that Monitum may help regenerate the EGX, decrease inflammation, prevent the adhesion of leukocytes to the endothelium, and assist with the stability of plaque in atherosclerotic conditions.
Antioxidant Protection:
The blend of antioxidants present in a variety of fruits, vegetables, and green tea helps counter oxidative stress and increases EGX’s natural defence against age-related, high blood glucose, and stress factors that negatively affect the body.
Quality & Safety:
Arterosil HP is manufactured under current Good Manufacturing Processes (cGMP), is tested for purity, contains no heavy metals, and is formulated using non-GMO (non-genetically modified organism) ingredients.

What Our Customers Say
Posted on Google Shivangini09 RichardsTrustindex verifies that the original source of the review is Google. Dr Menka is an excellent Gut health and longevity expert.She was very thorough with her assessment of the problem I was facing and prepared a detailed customised plan specific to my health condition and treated the diseases from the root cause ..Absolutely recommended.Thanks Doctor for all your help and support.Posted on Google dairhTrustindex verifies that the original source of the review is Google. Before meeting Dr. Menka, I had consulted numerous specialists from different disciplines in an effort to understand and treat my condition. Over the years, I underwent various tests, received different diagnoses, and was prescribed multiple medications, yet I always felt that the underlying cause of my health issues was never thoroughly investigated. The focus often seemed to be on suppressing the symptoms rather than understanding why they were occurring in the first place. As my symptoms persisted, I became increasingly discouraged and started to lose hope that I would ever find real answers or achieve lasting recovery. Meeting Dr. Menka completely changed my experience. Unlike many healthcare professionals I had been to, she took a comprehensive and holistic approach to my case. She carefully reviewed my medical history, previous investigations, symptoms, medications, lifestyle factors, dietary habits, stress levels, sleep patterns, and overall well-being. Rather than looking at each symptom in isolation, she worked to understand how everything was interconnected. Her treatment plan for me were practical and focused not only on the now but also on long-term health improvement and prevention. Today, I am feeling significantly better than I ever imagined possible before meeting her.Posted on Google Arpit GuptaTrustindex verifies that the original source of the review is Google. We are in the early stages of treatment with Dr Menka but we feel very reassured so far. She has been patient, thorough, and thoughtful in her approach. The testing was detailed, the plan looks promising, and we are are looking up to her as we continue the journey under her leadership.Posted on Google Carol fernandezTrustindex verifies that the original source of the review is Google. Highly recommend Dr Gupta! Over the last six months of working together, she has helped me achieve substantial progress in my health journey. I highly recommend her to anyone looking for a functional health practitioner.Posted on Google Prabakar SelvamTrustindex verifies that the original source of the review is Google. I have tried several treatments but functional medicine with Dr Menka and I think this is the best for GUT related issues.Posted on Google Priyanka KarthiTrustindex verifies that the original source of the review is Google. I want to thank Dr. Menka Gupta. I was suffering from some health problems and felt very scared, but after seeing her, my condition has been slowly improving. Thank you, doctor!Posted on Google Rajesh HathiramaniTrustindex verifies that the original source of the review is Google. Dr. Menka is extremely knowledgeable and helped resolve my issues.Posted on Google nitesh sharmaTrustindex verifies that the original source of the review is Google. Dr. Menka Gupta is the most competent functional medicine practitioners in Singapore, uniquely combining conventional medical training with deep functional medicine expertise — a combination that is still relatively rare globally. I initially consulted her for multiple interconnected issues: gut dysbiosis, chronic anxiety, fatty liver, and unexplained weight gain resistant to standard interventions. Rather than taking a symptomatic approach, she recommended a set of advanced functional diagnostics, including comprehensive stool analysis to assess gut microbiota composition (beneficial vs pathogenic bacteria), as well as specialized testing for neurotransmitter pathways and metabolic imbalances. These investigations identified disruptions in serotonin synthesis and conversion pathways, along with broader gut-liver axis dysfunction. Based on these findings, she designed a structured, four-phase gut restoration protocol (typically involving remove, replace, reinoculate, and repair phases), along with targeted nutraceutical and lifestyle interventions to support liver function, hormonal balance, and metabolic health. The outcomes have been significant: • Marked improvement in energy levels and cognitive clarity • Substantial reduction in stress reactivity and anxiety symptoms • Improved hormonal regulation • ~8 kg weight loss over 6 months, achieved sustainably • Overall enhancement in day-to-day performance (including the ability to handle long work hours without burnout) What stands out is her root-cause, systems-based approach, rather than a superficial or symptomatic treatment model. That said, this process requires patient accountability and consistency — the results are directly proportional to how well one adheres to the protocol. I’m genuinely grateful to Dr. Menka Gupta for the measurable and lasting impact she has had on my health and overall quality of life.Showing our latest reviews
Frequently Asked Questions (FAQ)
What does Arterosil HP actually do?
Arterosil HP provides ‘rhamnan sulfate’, which protects the endothelial glycocalyx from damage and the inner arterial lining. Rhamnan sulfate regulates how permeable blood vessels are to various things and helps create nitric oxide for normal blood flow. By helping to create nitric oxide, Arterosil HP also aids in creating defenses against damage from free radicals and decreasing inflammatory markers in endothelial cell cultures. Ultimately, this supports healthy arteries and circulation.
How is this different from other heart supplements?
Arterosil HP has a unique mechanism of action in promoting regeneration of the endothelial glycocalyx (EGX) through the use of a seaweed-sourced polysaccharide, MonitumRS rhamnan sulfate, which has been extensively studied for its direct ability to repair the EGX barrier. Other heart supplements typically focus on lowering cholesterol or high blood pressure, whereas Arterosil HP has been shown in studies to have specific benefits to the endothelial glycocalyx, including stabilizing atherosclerotic plaque.
Is it safe to take Calroy Health Sciences Arterosil HP with blood thinners?
No contraindications are known based on the published literature or from product data, which show no negative interactions with Arterosil HP. Research over the past 25 years has been conducted at various dosages, with no reports of toxicity due to its natural polysaccharide source. Contact your healthcare provider or practitioner if you would like personalized advice regarding this product.
I do Intermittent Fasting. Will Arterosil break my fast?
Arterosil (HP) has no calories and can be taken with food to help aid digestion after meals as well as improve compliance, however, it will NOT raise insulin levels or metabolically interrupt a FAST. Also, you can open the capsules and mix the contents into food when necessary during your eating times.
Can I take Arterosil HP if I have a shellfish allergy?
Yes! Arterosil is a shellfish-free, fish-free product manufactured from Green Seaweed. There are no Crustaceans in the product, and it is labeled free of the majority of allergens, including Shellfish, Gluten, Dairy, Soy, nuts, and Eggs.
