Biohacker-backed: The Methylene Blue supplement tied to RFK Jr. is on sale for Prime Day
The mysterious smurf-blue supplement that is suddenly the talk of the town in the wellness world has found a new home… in your Amazon cart.
Marked down to just $24 for Prime Day, Methylene Blue is one of the most buzzed-about supplement deals available during the major retail sale. Over 10,000 shoppers have picked up a batch in the last month alone, and it has some high-profile supporters, too.
The solution recently emerged in the headlines after Robert F. Kennedy Jr. was spotted sprinkling some blue droplets into his drink, mid-flight. The viral clip set the internet into a sudden frenzy, with one user suggesting it's 'one of the best-kept secrets in biohacking.'

As it turns out, experts have been studying Methylene Blue for centuries. Originally, it was used as a dye to stain textiles, then tested as a malaria treatment, an antipsychotic, and now, a brain booster that biohackers like Bryan Johnson and Dave Asprey have added to their wellness routines.
The compound is said to support mitochondrial function, enhance cellular energy production, and boost overall brain health, and users say that they feel the benefits fast.
'I've been using this pharmaceutical-grade methylene blue for a few weeks now, and I can genuinely feel the difference,' one Amazon reviewer shared. 'Within days, I noticed better mental clarity and focus, especially during long work sessions or those mid-afternoon slumps.'

UnitedHealth's Campaign to Quiet Critics
Mary Strause, a filmmaker in Wisconsin, logged on to Amazon's video-streaming service in late May so she could share a link to her latest project, a docuseries that harshly criticized the U.S. health care industry. She was surprised to see that her video had vanished. Ms. Strause had no way of knowing it, but the video had been taken down after a law firm working for UnitedHealth Group, one of the country's largest health care companies, sent a letter warning Amazon and another streaming service, Vimeo, that the video was defamatory. It was the latest salvo in an aggressive and wide-ranging campaign to quiet critics. In recent months, UnitedHealth has targeted traditional journalists and news outlets, a prominent investor, a Texas doctor and activists like Ms. Strause and her father, who complained about a UnitedHealth subsidiary. In legal letters and court filings, UnitedHealth has invoked last year's murder of Brian Thompson, the chief executive of the company's health insurance division, to argue that intense criticism of the company risks inciting further violence. The tactics have had an impact. Amazon and Vimeo both removed Ms. Strause's film. The Guardian postponed publishing an investigation of the company after UnitedHealth sued over a previous article it said was defamatory. UnitedHealth joins a growing group of companies and wealthy individuals, including President Trump, who are using legal threats and lawsuits to deter or penalize criticism. Want all of The Times?

I love my Garmin sleep tracker, but these 4 cheap alternatives are almost as good — starting from $64 for Prime Day
I've been a dedicated wearer of top-rated Garmin watches for over seven years. The brand has seen me through many half marathons, a marathon and triathlon, and one of the key health metrics I've tracked to get ready for these challenges is my sleep. A reliable sleep tracker keeps me accountable when it comes to maintaining a consistent sleep schedule and following sleep-friendly habits (we're talking getting enough daily light and avoiding too much screen time in the evening) to boost my sleep score. If I wasn't quite so attached to my Garmin Forerunner 255 and was shopping Prime Day sleep deals with a $200 budget, these are the sleep trackers I'd buy... 1. Fitbit Inspire 3: was $99.95 now $74.95 at AmazonThe Fitbit Inspire 3 is a top-rated affordable sleep and fitness tracker that sits subtly on your wrist. At its budget price point, you can't expect all the bells and whistles of premium Garmin trackers, but it gives you an accurate measure of your sleep duration. For more in-depth sleep data (sleep score and sleep cycle info), you can upgrade to a Fitbit Premium subscription at $9.99/month. At under $75 we think the Fitbit is a great-value smart watch for anyone in need of basic sleep insights. Our review: ★★★★½ User score: ★★★★½ (based on 19,170+ reviews) 2. Samsung Galaxy Watch 7: was $299.99 now $159.99 at Amazon The Samsung Galaxy Watch 7 is arguably the best sleep tracking watch you can get for under $200. It gives you a daily sleep score AND a daily energy score collating sleep and workout data to give you a better understanding of how well your body is recovering. Impressively, it also measures blood oxygen levels and skin temperature, and boasts FDA-authorized sleep apnea detection. All of that comes with 47% off now, slashing the price to $159.99 (was $299.99) — we think that's a super deal. If you dislike wearing a watch to bed, you could get the same Samsung sleep tracking experience with the Samsung Galaxy Ring, though it comes at a higher price ($399.99 $299.99 at Amazon this Prime Day). Our review: ★★★★½ User score: ★★★★½ (based on 3,280+ reviews) 3. Amazfit Helio Ring: was $199.99 now $149.99 at AmazonThe Amazfit Helio ring may not be selling as fast as the retailers expected (it got a major price cut in October 2024), but our reviewer says it offers "solid" sleep insights that are "a near match with other sleep-tracking devices", even if the data on offer isn't as "detailed and digestible" as you'd get from the likes of Samsung. If you're in the market for an affordable sleep-tracking ring, we think this is a reliable option. But you'll want to make the most of Amazon's 25% off while it lasts. Our review: ★★★★User score: ★★★½ (based on 150+ reviews) 4. Hadrono smart health wristband: was $159 now $63.99 at AmazonEssentially a Whoop dupe, the Hadrono is a faceless cloth band worn on the wrist to track your daytime activities and nightly sleep quality. Admittedly, we haven't tested this tracker ourselves, but customers say its functionality is comprehensive considering its budget price point, with sleep tracking being one of the "most useful" features. With a huge 60% off now, you can grab this sleep-tracking wearable for just $64 — you simply won't find a well-recommended sleep tracker cheaper elsewhere (trust me, I've been hunting all week). User score: ★★★★½ (based on 40+ reviews)
