Common Questions

What are the main alternatives to Flex Health?
Truemed and Sika Health are the closest substitutes. Both issue LMNs at checkout and accept HSA/FSA cards for wellness products. The right choice depends on which platform your preferred brand has integrated.
Does Truemed cover gym memberships like Flex does?
Truemed covers some gym and fitness brands, but Flex remains the strongest option for Equinox specifically. For most other gyms, both platforms work.
What about Sika Health for fitness?
Sika has fewer fitness partners than Flex but a broader supplement and nutrition catalog. If you're buying both fitness and supplements, you may end up using two platforms.
Are Flex alternatives more expensive?
No. Truemed and Sika are also free for buyers, with merchant-side processing fees.
Can I use my HSA card directly without Flex or an alternative?
Gym memberships and fitness products are only HSA-eligible with an LMN. The platforms exist to issue that LMN at checkout so the purchase qualifies.
How do I track purchases across multiple platforms?
Use HSA Trackr to centralize receipts and LMNs from any platform. The category tagging keeps your fitness, supplement, and other wellness purchases organized in one place.
