CARDIOVASCULAR HEALTH SUPPLEMENTS MARKET TRENDS

Growing Adoption of Plant-based and Algae-derived Omega-3 Products to Transform Product Portfolios

Growing preference for vegetarian, vegan, fish-free, and sustainably sourced supplements is encouraging manufacturers to expand their plant-based omega-3 product portfolios. Conventional botanical oils such as flaxseed primarily provide alpha-linolenic acid. In contrast, algal oils can directly supply DHA and, in certain formulations, EPA, making them suitable alternatives to fish-derived omega-3 products. This allows companies to serve consumers who avoid fish due to dietary preferences, allergies, taste, odor, or sustainability concerns. Algae-derived products can also reduce dependence on wild-caught marine resources while supporting clean-label and environmentally responsible brand positioning. As formulation technologies improve, manufacturers are introducing higher-potency algae oils, blended plant-based fatty acids, and softgels with reduced aftertaste. Therefore, the shift toward plant-based and algae-derived omega-3 is expected to diversify cardiovascular supplement portfolios and attract a broader consumer base. 

• For instance, in May 2024, MegaFood launched Plant-Based Omega 3-6-9, formulated with farm-traceable Ahiflower oil and fish-free algae oil. The product comprises ingredients such as omega-3 fatty acids and is positioned to support heart, brain, vision, and joint health. It also uses organic lemon oil to reduce aftertaste and was developed to minimize dependence on marine ecosystems. The launch highlights the increasing focus of supplement companies on combining plant-based sourcing, sustainability, and consumer-friendly formulations.

MARKET DYNAMICS

MARKET DRIVERS

Rising Burden of Cardiovascular Diseases to Increase Demand for Preventive Heart Health Supplements

The increasing prevalence of cardiovascular diseases is a key factor driving the global market demand. Major risk factors such as unhealthy diets, physical inactivity, obesity, high blood pressure, elevated blood glucose, and raised blood lipid levels are also becoming more common across aging and urban populations. As awareness of these risks increases, consumers are more likely to include cardiovascular health supplement ingredients in their daily wellness routines. This is encouraging manufacturers to introduce targeted and multi-ingredient formulations for cholesterol management, vascular support, circulation, and general cardiovascular wellness. Therefore, the expanding population affected by cardiovascular conditions and associated risk factors is expected to support sustained consumer demand. 

• For instance, in June 2025, Healthy Extracts launched STAT10, a CoQ10-based multi-ingredient nutritional formulation developed for consumers using statins. The product comprises CoQ10, omega-3 fatty acids, berberine, citrus bergamot, resveratrol, and vitamin C and is positioned to support heart health and nutrients that may be affected by statin use. The launch highlights the growing focus of supplement manufacturers on developing condition-specific products for large populations managing cholesterol and cardiovascular risks.

MARKET RESTRAINTS

Increasing Presence of Counterfeit Products to Hamper Market Growth

The growing availability of counterfeit and unauthorized supplements through unverified platforms may restrict the global cardiovascular health supplements market growth. Such products may contain incorrect ingredient quantities, undeclared substances, low-quality raw materials, or misleading labels that imitate established brands. Reports of fraudulent supplements can also reduce confidence in genuine products and make consumers more hesitant to purchase unfamiliar brands. Legitimate manufacturers may consequently face the burden of spending high costs on product authentication, traceability, quality testing, and consumer education. Therefore, increasing circulation of counterfeit products is expected to weaken consumer trust and restrain the market growth.

• For instance, in May 2026, Europol supported an international operation against a criminal network involved in producing and distributing counterfeit medicines and dietary supplements across several European countries. The network was associated with approximately USD 240 million in illicit transactions and promoted unauthorized supplements through misleading advertisements and fake endorsements. Such instances raise safety concerns, damage the credibility of legitimate brands, and discourage consumers from purchasing health supplements through less-regulated channels.

MARKET OPPORTUNITIES

Expansion of Personalized Nutrition and Condition-specific Heart Health Formulations to Create New Growth Avenues

The increasing shift from general wellness supplements toward personalized and condition-specific formulations is expected to create significant growth opportunities in the market. Consumers have different nutritional requirements depending on their age, lifestyle, dietary habits, health background, medication use, and cardiovascular risk factors. This is encouraging manufacturers to develop targeted products for cholesterol and triglyceride management, blood pressure support, vascular circulation, heart energy, and general cardiovascular wellness. Therefore, the expansion of data-driven personalized nutrition is expected to help manufacturers differentiate their products and reach consumers with specific heart health requirements. This represents a market opportunity rather than evidence that supplements can replace medical treatment.

• For instance, in March 2026, Herbalife acquired certain assets of Bioniq to expand its personalized nutritional supplement capabilities. Bioniq develops individualized formulations using consumers’ health history, questionnaires, blood test information, and a proprietary biomarker database. The development highlights the growing investment by established nutrition companies in scalable, technology-enabled and condition-relevant supplement solutions.

MARKET CHALLENGES

Building Consumer Trust Amid Misleading Marketing Claims to Pose Challenge to Product Adoption

The increasing presence of misleadingly labeled products is creating a major credibility challenge for the market. Products with little or no declared active ingredients may fail to provide the expected benefits, causing consumers to question the effectiveness of the wider supplement category. Exaggerated cardiovascular claims can further create unrealistic expectations and increase regulatory scrutiny. Consequently, legitimate manufacturers must invest in third-party testing, authentication seals, supply-chain monitoring, legal action, and consumer education, which raises operating costs. Therefore, maintaining trust while separating scientifically supported products from poor-quality alternatives is expected to remain a significant market growth challenge.

• For instance, in May 2025, Kaneka Nutrients announced market protection measures against counterfeit ubiquinol products after identifying an increasing number of products making misleading ingredient claims. Laboratory testing conducted with accredited third-party laboratories found that multiple products purchased through Amazon contained zero or negligible quantities of ubiquinol despite making substantially higher label claims.

Segmentation Analysis

By Product Composition

Multi-ingredient/Combination Supplements Dominated Owing to Their Ability to Address Multiple Cardiovascular Needs in Single Formulation  

Based on product composition, the market is categorized into single-ingredient supplements and multi-ingredient / combination supplements.

Multi-ingredient/combination supplements segment dominated the market as they cater to several interconnected factors, including cholesterol levels, blood pressure, circulation, oxidative stress, and cellular energy, which influence cardiovascular wellness. Products combining omega-3 fatty acids, CoQ10, magnesium, phytosterols, vitamins, and botanical ingredients allow consumers to address several of these factors through a single daily formulation. This reduces the need to purchase and manage multiple standalone supplements, improving convenience and supporting regular consumption.

• For instance, in June 2025, Nature’s Bounty introduced Advanced Vital Heart, a triple-action cardiovascular supplement containing clinically studied CoQ10, magnesium, and phytosterols. The product was designed to support cholesterol management, blood pressure already within the normal range, and healthy circulation. The launch highlights the growing focus of supplement companies on multi-ingredient products that address several cardiovascular wellness requirements through one formulation.

The single-ingredient supplements are expected to grow at a CAGR of 5.97% over the forecast period.

By Ingredient

Omega-3 Fatty Acids Held the Leading Share With Their Strong Consumer Recognition and Broad Cardiovascular Health Positioning

Based on ingredient, the market is segmented into omega-3 fatty acids, vitamins, minerals, coenzyme q10, plant sterols & stanols, herbal, botanical & fermented ingredients, amino acids, soluble fibers, and others.

In 2025, the omega-3 fatty acids segment held the largest cardiovascular health supplements market share as they are commonly positioned to support healthy triglyceride levels, cardiovascular function, blood flow, and general wellness, allowing to cater to broader target population than many specialized ingredients. Omega-3 products are also widely available in different strengths, price ranges, and in combinations with CoQ10, vitamins, and antioxidants. Their long-standing presence further supports repeat purchases and high brand familiarity. Therefore, broad consumer acceptance and extensive commercial availability enabled omega-3 fatty acids to account for the largest market share.

• For instance, in May 2024, Doctor’s Best launched Vegan Omega-3 with Elantria, an algae-derived, high-potency EPA and DHA supplement. The product was introduced as a sustainable alternative to fish oil and was positioned to support cardiovascular, eye, and brain health. This launch demonstrates the continued expansion of omega-3 portfolios to attract consumers seeking plant-based and fish-free heart health supplements.

The plant sterols & stanols segment is projected to grow at a CAGR of 6.95% during the forecast period.

By Health Benefit

High Consumer Awareness for Preventive Cardiovascular Care Boosted Cholesterol and Triglyceride Management Dominance

Based on health benefit, the market is segmented into cholesterol & triglyceride management, blood pressure support, circulation & vascular support, heart function, rhythm & energy support, general cardiovascular wellness, and others.

By health benefit, the cholesterol and triglyceride management segment captured the highest share. Consumers can obtain measurable cholesterol and triglyceride results through routine blood tests, which creates a clear and identifiable need for nutritional support alongside diet and lifestyle changes. This encourages demand for omega-3 fatty acids, phytosterols, soluble fibres, berberine, and plant-derived formulations positioned for lipid management. The segment also benefits from strong demand among middle-aged and older consumers who are increasingly focused on preventive cardiovascular care. It also provides manufacturers with a specific benefit that consumers can easily understand and track. Therefore, the large addressable population and clear preventive-health positioning supported the segment’s dominant share.

• For instance, in May 2024, Valbiotis launched ValbiotisPRO Cholestérol in France for individuals with mild-to-moderate hypercholesterolemia. The product contains Lipidrive, a patented natural supplements. The development highlights increasing commercial investment in scientifically positioned supplements specifically targeting cholesterol management.

The others segment is projected to grow at a CAGR of 6.98% during the forecast period.

By Dosage Form

Softgels Dominated Owing to Their Suitability for Oil-based Ingredients and Convenient Daily Consumption

Based on dosage form, the market is segmented into tablets, capsules, softgels, gummies & chewables, powders, liquids, and others.

In 2025, the softgels segment dominated the market as several major cardiovascular supplement ingredients such as fish oil, krill oil, algae oil, and lipid-based CoQ10 formulations are well suited for encapsulation in soft gelatin shells. Softgels can contain liquid or oil-based formulations in a pre-measured dose, helping manufacturers maintain product consistency and simplify daily consumption. Their smooth outer shell also makes them easier to swallow for many adults compared with large compressed tablets. Encapsulation can reduce consumers’ direct exposure to the taste and smell of marine oils, which improves the overall product experience. As a result, the strong connection between softgels and high-volume oil-based cardiovascular products supported the segment’s leadership.

• For instance, in December 2025, Rouzel Pharma launched EDO-3 Softgel Capsules containing omega-3 fatty acids, including EPA and DHA. The company positioned the formulation for cardiovascular, cognitive, joint, and general wellness support and highlighted the softgel format’s convenience and ease of swallowing. The launch reflects the continued preference for softgel delivery in oil-based omega-3 supplement formulations.

The gummies & chewables segment is projected to grow at a CAGR of 8.65% over the forecast period.

By Distribution Channel

Retail Pharmacies and Drug Stores are the Most Favored Channel Owing to High Consumer Trust and Immediate Product Accessibility

Based on distribution channel, the market is segmented into retail pharmacies & drug stores, supermarkets & hypermarkets, specialty health & nutrition stores, online retail, direct selling, and others.

In 2025, retail pharmacies and drug stores dominated the market as they provide consumers with convenient access to cardiovascular supplements alongside prescription medicines and other preventive-health products. The availability of pharmacists and trained store personnel can also help consumers compare brands, strengths, dosage forms, and potential medicines. Large pharmacy chains offer extensive physical networks, established consumer trust, promotional programs, and strong shelf visibility for recognized supplement brands. Therefore, frequent consumer visits, trusted healthcare positioning, and broad product availability supported the channel’s dominant market share.

• For instance, in December 2024, Nature’s Bounty launched its Plant-Based Omega-3 supplement across major retailers, including CVS and Walgreens. The algae-derived product was supplied as a once-daily softgel containing EPA and DHA and was positioned to support heart, joint, and skin health. Its availability through leading pharmacy chains demonstrates the importance of retail pharmacies and drug stores in providing mass-market access to cardiovascular health supplements.

The online retail segment is projected to grow at a CAGR of 8.62% from 2026 to 2034.
