There were Prime Day supplement deals available on probiotics, multivitamins, protein powders and more—these are the ones worth buying in 2024

Supplementing your diet with vitamins, minerals, probiotics and protein powder can be a good way to hit your health goals. While these things are readily available in food sources, a lot of people (me included!) struggle to get the recommended daily dosage.
There were a lot of discounts in the Prime Day supplement sales, and I rounded up the deals I recommend. Below, you’ll only find supplements shown to improve health outcomes when taken by people who are consuming below the recommended daily amount.
As a reminder, only Prime members can access the deals when they go live. But you can sign up for a 30-day free trial and cancel your membership after the event. If you’re looking for other fitness deals, my colleagues are also keeping an eye on the best Prime Day weights deals and Prime Day kettlebell deals.

FAQs
When is the next Prime Day and is it only once a year?
Prime Day 2024 took place on the 16th and 17th of July, but we can expect a second two-day sales event in the fall, so keep your eyes peeled.
Amazon's summer Prime Day event started on Tuesday, July 16th, and drew to a close at midnight the following day.
In recent years, Amazon has also been giving us a second bite of the cherry with a Prime Day-like sale in October, so if you don't like any of the deals you see this time around, it won't be long until another Prime Day swings around.
Amazon Prime Day first began in 2015 to celebrate Amazon's 20th anniversary.
Is it worth buying supplements during Prime Day?
While you should aim to get most, if not all, nutrients from your diet, it's not always possible to get everything your body needs from food alone and supplements can help address vitamin deficiencies.
If you eat a primarily plant-based or vegan diet, you may want to supplement your diet with vitamin B12, typically found in meat and other animal products. If you don't get enough exposure to sunlight, you might want to top up your vitamin D intake.
Our needs change over the years, so it's worth using supplements as you age too, but always seek advice from your doctor before taking a new supplement.
