Prime Day supplement deals: when do sales start?
Amazon Prime Day will happen in July 2022, back to its original mid-year slot following adjustments in 2020 and 2021 due to the pandemic. Although we don't know the exact date yet, we expect deals to be released a couple of weeks earlier too.
That doesn't mean you need to wait until the event itself to find great deals on supplements. Amazon regularly offers discounts on some of the top supplements, including the best supplements for joints, and we've collected together money-saving deals you can use right now.
Amazon first launched Prime Day in 2015 for Prime subscribers to shop with exclusive discounts on a range of products for a single day. For the third annual shopping event in 2017, Amazon extended Prime Day across two days in July.
The yearly two-day event continued until 2020, when the COVID-19 pandemic affected businesses and supply chains worldwide. In that year, Amazon shifted Prime Day to October and then held the 2021 event in June.
Prime Day supplement deals: what to look out for
While you can get most nutrients from your diet, it's not always possible to get everything your body needs from food alone. If you can't add oily fish to your diet, there are so many benefits of fish oil that it's a good idea to use Prime Day to stock up on these omega-3 supplements.
Similarly, 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. 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.
There may be discounts or savings on the best menopause supplements to help you manage hot flushes, mood swings, and night sweats as you go through menopause, while the best protein powder for women supports muscle growth and maintenance.
When you exercise, small tears appear in your muscle fibers. Your body uses protein to repair these, and protein powders are a great way to ensure your muscles get everything they need to promote recovery and encourage muscle growth.
What makes a good Prime Day supplement deal?
To get the most from Prime Day supplement deals, it's worth considering what type of supplement would best support your body. If you're unsure, talk to your doctor or healthcare provider about your specific needs.
Supplements are usually branded or marketed towards certain lifestyles. These might be just what you need, but if you're after a vitamin D supplement, you might not need a more comprehensive multi-vitamin.
If you eat a vegan diet, then fish oil supplements and B12 vitamins are a good way to top up your nutrient levels, but be sure to look out for brands that specifically mention that they are vegan-friendly, as not all supplements are.
When searching for a Prime Day supplement deal, price is often a significant consideration. Before we feature any deals, we investigate historical prices, compare them against other retailers, and put them into context so you can make an informed choice.
