If you can't get sufficient vitamins and minerals through your diet alone, then supplements are a great option. Plenty of people use these tablets, powders and gels to make sure they're hitting their recommended daily dosage.

It can be pricey to stock up on these supplements, but luckily Amazon's October sales event (which is officially called Big Deal Days) has arrived and brought plenty of discounts with it. I've trawled through the sales to find the best savings and rounded them up below.

You need to be a Prime member to access some of these deals, but the good news is you can get a 30-day free trial on the platform, and cancel when the sales have ended.

FAQs

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

Amazon's summer Prime Day event started on Tuesday, July 16th, and drew to a close at midnight the following day. But Amazon's second sales event (called Big Deals Day) is happening right now and will run from October 8th to October 9th.

While it's unlikely that Amazon will hold another special sales event this year, they will undoubtedly be taking part in Black Friday on November 29th.

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.
