The Brief

Welcome back, Wellworthy readers.

If you’ve ever wondered whether longevity is shaped, inherited, or some mix of both, new research provides the clearest explanation yet.

Plus, we asked an NYU longevity researcher to break down what the data actually says, and what people get wrong.

Here’s what’s inside:

• The new science on how genetics shapes lifespan

• A better way to know what's in your supplements

• THIS WEEK: Creatine in your morning coffee, Ultrahuman's new smart ring, and skincare made from edible ingredients

Here we go!

The Breakdown

A new study in Science suggests lifespan is roughly 50% heritable.

Jordan Weiss, PhD, and longevity researcher at NYU, puts it plainly: "Heritability is a population-level statistic. It explains variation across a group, not what will happen to any one person."

In other words, it's a measurement tool, not a personal forecast.

Why it matters

The other half of the equation comes down to what researchers call the exposome: everything you're exposed to over a lifetime. 

Food, air, stress, relationships, and the environment you live in all play a role. 

Weiss points out that the doubling of human life expectancy over the last century was driven mostly by sanitation, vaccines, and better living conditions—not changes in DNA.

"Genetics provides a starting point, not a script," he says.

The takeaway

Genes help explain why outcomes vary, even when habits look similar. “Your genome is not going to tell you anything that contradicts the fundamentals," Weiss adds.

For the half you can influence, Weiss’s advice is simple: move daily, strength train, protect your sleep, eat mostly whole foods, and invest in your relationships. 

No matter your genes, the playbook remains the same.

Fitness & training

Peloton dropped two new programs this week: a 12-week HYROX training plan timed for HYROX NYC this May, and 12 new perimenopause and menopause classes built with Halle Berry's wellness platform Respin. Start training.

Bandit Running's Spring 2026 collection, Quiet Miles, is 69 pieces built around thermoregulation, chafe-free construction, and storage. The standout is the Striped Cadence Half Tights, which pack seven pockets into a pair of compression tights. Shop here.

Pruzan is a UK running brand founded by two female athletes, and the SS26 collection makes the case that technical running gear can still feel feminine. Their ethos? Harmonize performance and beauty in silhouettes built for distance. Shop the collection.

Nike's Running Is Mental collection launches with a three-shoe lineup—and each one comes with a metallic incense holder. Running brands talk about mental toughness constantly, but Nike's sensory research continues to go deeper, reminding us just how much recovery and mental state affect performance. See the drop.

Lululemon's new ShowZero technology wants to make sweat virtually invisible (about time) by changing how light interacts with the fabric when wet. Developed with tennis player Frances Tiafoe, it's launching in his custom kit at the BNP Paribas Open this week. Learn more.

Supplements & nutrition

Amulet's Daily Cycle Support gummy is built around a stat worth sitting with: women typically feel their best fewer than one third of the month. The formula uses ingredients like bio-identical lactoferrin and creatine monohydrate to support mood, strength, immune health, and reduce bloating throughout the month, not just on the easy days. Try it here.

Bish Bar is a protein bar built around a woman's menstrual cycle, with 12g of plant-based protein and micronutrients like magnesium, B vitamins, iron, and vitamin D formulated to support all four phases. The flavors are named accordingly: Date Yourself, Pillow Talk, and Sunset Walk. Shop now.

Bulletproof Coffee + Creatine stacks 5g of creatine monohydrate into an instant black coffee. Creatine works best when you take it daily, and this makes sure you never forget it by making it part of the habit you're already keeping. One scoop, hot or cold water. Try it here.

Vital Proteins keeps coming up with ways to make taking collagen even easier, this time in sparkling water. Each can has a full serving of collagen peptides, 100% daily vitamin C, 0g sugar, and 15 calories. Grab it in flavors like Strawberry Blossom or Lemon Lime. Learn more.

Wellness tech & self-care

Ultrahuman's new Ring PRO and its AI layer, Jade, are built around what to do with your smart ring data once you collect it. It’ll surface real-time guidance across heart rate, glucose, and recovery as it happens, not after the fact. Check it out.

Sunkissed by Heaven makes skincare from ingredients you could eat: beef tallow, raw honey, jojoba oil, and beeswax for the moisturizer, plus zinc oxide for their SPF50 sunscreen. The idea? Your skin deserves the same nutritious ingredients as your diet. Shop now.

On Our Radar 

What's moving in wellness this week → 

Urban Iron is back in NYC. After its fall debut, Urban Iron has built a real following. It’s now back in the city on April 19th with 200 athletes, a route from FiDi to Midtown to South Williamsburg, and a finish line at Rivian with ice baths and a live DJ. The hybrid race combines 8 miles through NYC with functional workout stops across Manhattan and Brooklyn. If you've been curious, now's the time.

Competitive fitness gets a consistent rulebook. XENOM launches June 27-28 in Frisco, Texas, with 10 fixed events testing athletes across strength, endurance, and metabolic conditioning. With 11 events already planned across the US and Europe, it could become a global standard that athletes and spectators can follow anywhere.

Supplement labels are getting fact-checked. SuppCo tested 500+ products against their labels and found that over half didn't match their labels. Now the brand has launched TESTED, an independent certification that buys products anonymously at retail, sends them to an accredited lab, and publishes every result, pass or fail. Essentially, the secret shopper of supplements.
