Supplements that Work
Vitamins, herbs, antioxidants and more for mental health
Here you’ll find natural options that work, meaning they improved mental health in at least one controlled trial. Some are part of a healthy diet (eg, omega-3, probiotics). Others have brain effects that are similar to those of medications (eg, lavender oil, saffron). Indeed, supplements can be just as powerful, and just as risky, as meds. So what’s the difference?
The difference is more legal than scientific. In the US, supplements are difficult to copyright, and without copyright protection few companies can afford to launch them as medications. Instead, they may modify herbs to make medications, like bupropion (from the African Khat plant) and valproate (from the valerian flower). In rare cases, the natural form does make it to market as a medication, like Epidiolex (CBD oil, used for seizures) or lithium (a natural mineral used for mood disorders). Outside the US, more supplements are regulated as medications, like melatonin and lavender oil.
An important difference between supplements and medications is in their manufacturing. The quality is higher and more consistent for medications. To improve on that, I’ve selected products here that are backed by testing from independent groups like US Pharmacopeia and Consumer Lab.

Medication Tools
Pill Boxes
You’ll need a large or extra-large box for plus-sized vitamins like omega-3. Mix with your meds, and use a two-, three- or four-sided box if taking multiple doses a day.
Tip: Get four boxes so you only have to fill them once a month.
Discount Meds
For brand name medications, check the official website for coupons (the website is the brandname.com, e.g. trintellix.com).
GoodRx. Searches your local pharmacies for the lowest out-of-pocket price. Note that Costco often has the lowest price and you don’t need to be a member to use their pharmacy.
Cost Plus Drugs Mark Cuban’s deep discount pharmacy.
Needs Meds. Discount card and connects you to various savings programs, including patient assistance programs for people who need brand name medications but have a low income.
Save on My Meds. Checks for lowest price if you’re paying out of pocket, also verifies if an online pharmacy is safe.
Refill Wise. Discount card.
Overseas Pharmacies
If you plan on getting your meds through an online or overseas pharmacy, there are ways to do it safer and ways that are riskier. Those risks are big, as many overseas pharmacies ship poorly made products with dangerous ingredients in them. Deception is rampant. Most of the ones that advertise as “Canadian” don’t even sell medications that would pass inspection in Canada.
The safest online sources are those with a “.pharmacy” at the end of their web address. Two groups that can check the safety, and give you a list of safe online sources, are:
Buy Safely. Type in your pharmacies website to check if it’s safe. Or download their list of verified pharmacies.
