Best Supplemental Insurance Companies in 2026: 8 Tools Compared

#1

Aflac

Best for: Individual accident and critical illness plans

Visit aflac.com

Aflac is the best-known supplemental insurer in the US, and its individual range covers accident, cancer, critical illness, hospital, short-term disability, dental, vision, and life plans. Benefits are generally paid in cash to the policyholder, which means you can use the money for medical bills, rent, or other costs while you recover. That flexibility is the core appeal of supplemental coverage. Aflac sells both individual plans and group plans through employers, with group coverage underwritten by its Continental American companies. Availability, benefit amounts, and premiums vary by state and by the plan level you choose, and riders may add cost. If you want a single carrier for several supplemental plans, Aflac is the natural first quote.

Colonial Life

Best for: Voluntary workplace benefits

Visit coloniallife.com

Colonial Life focuses on voluntary benefits offered through workplaces. Its plans cover life, accident, disability, critical illness, hospital, dental, and vision, with enrollment help in person, by phone, online, or virtually. That enrollment support matters, since many employees pick benefits once a year with little guidance. The company also serves many public-sector employers, including schools and local governments, which suits workers in those sectors. The trade-off is access: most Colonial Life coverage comes through an employer or broker rather than a direct individual purchase. If your employer offers Colonial Life during open enrollment, compare its plans against any individual options you hold.

#3

MetLife

Best for: Employer group benefits

Visit metlife.com

MetLife is a leading provider of employee group benefits in the US, covering dental, vision, disability, life, accident, and critical illness plans for workplaces of many sizes. Employers can build a package that pairs major medical coverage with supplemental plans that help staff handle deductibles, copays, and income gaps during illness or injury. Individual buyers will find fewer direct options than at Aflac, since MetLife's strength sits in group enrollment. For employers and benefits managers, MetLife's scale, administration tools, and broker support are real advantages. Ask your employer whether MetLife plans are on offer, and check how each plan pays: some pay providers, while others pay cash to the employee.

Mutual of Omaha

Best for: Life, Medicare supplement, and group plans

Visit mutualofomaha.com

Mutual of Omaha covers life insurance, Medicare supplement plans, and employer-based benefits, with individual and group options. Medicare supplement plans help cover costs that Original Medicare does not pay, such as copayments and coinsurance, while group plans add disability, dental, and life coverage for employees. The company also offers financial planning support through representatives, which can help buyers who want protection and retirement planning in one conversation. Direct individual supplemental choices are narrower than Aflac's, so buyers seeking accident or critical illness cover should confirm which plans are open in their state. For Medicare-age buyers and employers, Mutual of Omaha is a solid, established option.

#5

Humana

Best for: Health-linked supplemental coverage

Visit humana.com

Humana is best known for Medicare Advantage, Medicare supplement, and Part D plans, and it also offers dental, vision, and supplemental coverage that pairs with health plans. Members get online tools for claims, benefits, and provider search, plus care programs that support chronic conditions and preventive care. The main limit is focus. Humana's supplemental range is tied closely to its health and Medicare business, so working-age buyers seeking standalone accident or critical illness cover may find a wider choice elsewhere. For Medicare enrollees, though, buying supplemental and health coverage from one carrier simplifies claims and provider questions. Check open enrollment dates, since Medicare plan changes follow a set calendar.

#6

Cigna Healthcare

Best for: Dental, vision, and supplemental health plans

Visit cigna.com

Cigna Healthcare offers health, dental, and vision plans, with supplemental health products that help cover costs beside major medical coverage. Dental and vision plans suit buyers who want routine care covered, while supplemental health plans can help with hospital and illness costs. Virtual care is available at no cost share for eligible preventive care and urgent care on some plans. Availability varies by location and plan type, and all policies carry exclusions and limits that you should read before buying. Cigna suits buyers who already use Cigna health or dental plans and want supplemental cover from the same carrier. Compare its dental and vision networks in your area, since network size decides how useful a plan is in practice.

#7

Transamerica

Best for: Workplace and individual protection

Visit transamerica.com

Transamerica offers life insurance, workplace retirement plans, and employee benefits that include life, disability, and supplemental insurance. Employees may access coverage through an employer program, while individuals can buy life insurance through agents, the Transamerica Agent Network, or affiliated financial professionals. That agent-led model suits buyers who want advice with a purchase, but it makes direct price comparison harder, since quotes depend on age, health, and plan design. Transamerica's scale is large, with millions of customers and tens of billions paid in claims and benefits. If your employer offers Transamerica benefits, review them beside any individual plans you hold, since workplace plans often cost less than individual cover.

#8

Unum

Best for: Disability and leave benefits for employers

Visit unum.com

Unum focuses on financial protection for workers, with disability insurance, life insurance, and leave management for employers. Its absence platform helps HR teams manage leaves, track compliance, and support employees returning to work, while integrations with HR systems such as Workday, ADP, and UKG reduce manual admin. Unum protects tens of millions of people worldwide, and its strength is income protection: short-term and long-term disability plans that replace part of pay when illness or injury keeps an employee out of work. Individual buyers will find most Unum coverage through an employer, so check your workplace benefits first. For employers, Unum's leave and disability combination is one of the strongest group packages on this list.
