FAQs

When is Prime Day and is it only once a year?

The first 2023 Amazon Prime Day began on July 11 and ran until July 12—the second one is kicking off on October 10 and will end on October 11. The new event is technically called the Prime Big Deal sDay.

The annual event started in 2015 as a celebration of Amazon's 20th anniversary and has since expanded to become a two-day sale where Prime subscribers can get additional discounts and savings on products across the entire range.

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.

If you regularly train and home and you're looking to pick up some new equipment at a discount, make sure to check out our roundup of all the best Prime Day weights deals to save on kettlebells, dumbbells, and barbells.

How to find good Prime Day supplement deals

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.
