💡 Quick Answer: Yes, dietary supplements are HSA eligible when used to prevent or treat medical conditions. The IRS recognizes nutritional supplements as qualified medical expenses under Publication 502 when recommended by a healthcare provider. You need a Letter of Medical Necessity, and Crates Health gets you approved in minutes.
The Hidden Cost of Your Supplement Stack
Your supplement collection cost is getting out of control. Between the morning vitamins, post-workout protein, and that adaptogen blend your friend swears by, you’re easily dropping $100+ monthly.
Americans spend $50.8 billion annually on dietary supplements, according to Nutrition Business Journal’s 2023 report. The average supplement user spends $98 monthly. That’s $1,176 yearly that could be tax-free with proper documentation.
At Crates Health, we’ve helped thousands of users save 30-40% on their supplement costs through HSA/FSA reimbursement. Most people have no idea that preventing nutritional deficiencies counts as medical care under IRS guidelines. Your employer definitely won’t mention it, and your HSA provider probably hopes you never figure it out.
Why Your Supplements Are Actually Medicine
The medical necessity of supplements isn’t just wellness influencer talk. It’s documented fact. According to the CDC’s National Health and Nutrition Examination Survey:
- 95% of American adults don’t meet the recommended daily intake for vitamin D
- 48% are deficient in magnesium
- 90% don’t consume adequate omega-3 fatty acids
Basically, if you eat normal food and work inside, you’re probably deficient in something.
A study published in JAMA concluded that “most people do not consume an optimal amount of all vitamins by diet alone” and recommended that all adults take vitamin supplements. Not some adults. All adults.
The American Heart Association recommends omega-3 supplementation for cardiovascular disease prevention. The Endocrine Society recommends vitamin D supplementation for adults at risk for deficiency (spoiler: that’s basically everyone).
These aren’t wellness trends from uninformed people. They’re medical recommendations from top doctors and researchers.
What the IRS Actually Says
According to IRS Publication 502, you can include in medical expenses “the cost of nutritional supplements recommended by a medical practitioner as treatment for a specific medical condition diagnosed by a physician.”
Breaking that down:
- Recommended by a medical practitioner: Any licensed healthcare provider works
- For a specific medical condition: Including prevention (this is key)
- Documented properly: Through a Letter of Medical Necessity
The key insight: Prevention of specific conditions qualifies as medical care under IRS rules. You don’t need an existing diagnosis. Preventing vitamin D deficiency, cardiovascular disease, or muscle loss all qualify as specific medical conditions.
Which Supplements Actually Qualify
Vitamins and Minerals
Your basic vitamin routine generally counts when preventing, managing or reversing conditions:
- Vitamin D: The National Institutes of Health reports that vitamin D deficiency affects 41.6% of Americans. If you WFH and barely see sunlight, you’re probably in this group.
- B-Complex Vitamins: Essential for not feeling exhausted all the time. Research shows B12 deficiency in up to 15% of the general population.
- Iron: The WHO identifies iron deficiency as the world’s most common nutritional disorder. Fun fact: it’s not just a vegetarian problem.
- Magnesium: Studies indicate 50% of Americans consume less than the recommended amount. That eye twitch? Could be magnesium.
Protein and Recovery Supplements
Your post-workout routine is medical care:
- The International Society of Sports Nutrition confirms protein powder prevents muscle loss (sarcopenia if you want the fancy term)
- Research in the American Journal of Clinical Nutrition shows protein supplementation prevents age-related muscle decline
- Creatine, BCAAs, and glutamine all have legitimate medical applications
Omega-3 Fatty Acids
Your fish oil isn’t just trendy:
- Meta-analysis in Mayo Clinic Proceedings found omega-3 supplementation reduces cardiovascular mortality by 16%
- The American Heart Association literally recommends them for heart disease prevention
Probiotics
Gut health is having a moment, but it’s also legitimate medicine:
- Clinical reviews demonstrate probiotics’ effectiveness for digestive health
- The World Gastroenterology Organisation has actual guidelines on probiotic use
The Letter of Medical Necessity: Your Golden Ticket
Here’s where it gets tricky. Your regular doctor might look at you weird when you ask for documentation that your protein powder is medical. They went to med school to prescribe statins, not supplements.
After helping thousands of users through Crates Health, we know exactly what makes a compliant LMN:
- Specific condition or prevention goal: “Preventing vitamin D deficiency” works
- Medical rationale: Why you specifically need supplementation
- Specific supplements recommended: The actual products and dosages
- Duration of treatment: Usually 12 months for preventive care
- Provider credentials: Licensed healthcare provider’s information
Our network of providers gets it. They understand that preventing disease before it happens is just as important as treating disease. They can evaluate you online and issue a comprehensive LMN that covers your supplementation routine.

Quality Actually Matters Here
When you’re using pre-tax dollars, don’t cheap out:
- Third-party testing: NSF, USP, or ConsumerLab certification means it’s legit
- GMP compliance: Good Manufacturing Practices = not made in someone’s garage
- Clinical dosing: The amounts actually used in studies, not pixie dust
- Bioavailability: Forms your body can actually use (looking at you, magnesium oxide)
Better brands often provide better documentation for HSA reimbursement too, which makes the whole process smoother.

Stop Leaving Money on the Table
Look, you’re already buying these supplements. You’re already taking them every day. The only question is whether you want to save 30-40% or keep paying full price for no reason.
