The Supplements That Have Changed My Life in My 40s

I’ve become a lot more intentional about what I put into my body in my 40s. Not in an obsessive way and I’m definitely not taking anything because it’s trending. I think what’s important is supporting your body in your 40s.

Your hormones shift, recovery slows, energy fluctuates, skin changes and muscle mass declines if you’re not paying attention. I realized that skincare alone wasn’t going to carry me through this particular decade! Beauty, strength, and longevity are inside-out conversations now.

These are the supplements that have genuinely made a difference for me.

Happy Aging NAD+ Advanced Longevity Formula

If there’s one supplement I’ve researched the most, it’s this one.

NAD+ (nicotinamide adenine dinucleotide) is a molecule that already exists in your body. It plays a critical role in cellular energy production, DNA repair, and overall metabolic function. The problem is that NAD+ levels decline significantly as we age, and by the time we’re in our 40s, they’re far lower than they were in our 20s.

Lower NAD+ levels are linked to fatigue, slower recovery, duller skin, reduced cellular repair, and many of the visible and internal markers of aging.

This is where longevity beauty becomes really important.

We talk about anti-aging constantly, but the real conversation should be about healthy aging. Supporting your cells so they function optimally for longer. NAD+ is central to that.

And then we have the “12 Hallmarks of Aging.” These are the biological processes scientists identify as the drivers of aging…things like cellular deterioration, mitochondrial dysfunction, stem cell exhaustion, and chronic inflammation. NAD+ plays a role in several of these pathways, particularly in supporting mitochondrial function and DNA repair.

Basically, it helps your cells produce energy and repair themselves more efficiently.

For women over 40, this really matters. Energy isn’t what it used to be, skin turnover slows down, and inflammation can creep up. And recovery from workouts takes much longer.

Since incorporating Happy Aging NAD+ Advanced Longevity Formula, I’ve noticed steadier energy, better recovery, and a general sense that my body feels supported rather than depleted. It’s not dramatic or overnight, but it’s cumulative. And that’s exactly what longevity is about.

Creatine

Creatine is one of the most researched supplements in the world, yet women still hesitate so much around it - it really isn’t just for bodybuilders!

As we age, we naturally lose muscle mass. That decline accelerates in our 40s and above, especially with hormonal changes. Muscle isn’t just aesthetic…it’s metabolic. It supports bone density, glucose regulation, strength, and longevity.

Creatine helps improve strength output and recovery. For me, it’s been a game changer in the gym. I feel stronger during sessions, I recover better, and I’ve seen visible improvements in muscle tone.

There’s also growing research around creatine supporting cognitive health, which becomes increasingly relevant as we age. It’s simple, it works, and it supports long-term strength.

Vitamin D

Vitamin D is one of those supplements that so many women are unknowingly deficient in. Low Vitamin D levels can affect mood, immunity, bone health, and energy. For women over 40, bone density becomes especially important. Supporting it early matters.

After having my levels tested and supplementing properly, I noticed more stable energy and fewer of those low days.

Colostrum

Colostrum has become more popular recently, but it’s not actually that new. It’s the first form of milk produced after giving birth and is rich in growth factors, immune-supporting compounds, and nutrients. For me, the biggest benefit has been gut support.

Gut health influences everything…from skin clarity to inflammation levels to nutrient absorption. When my gut feels good, my skin behaves better. My energy is more stable. My body feels less reactive. In your 40s, that internal stability matters more than ever.

Viviscal

Hair changes so much in your 40s. Hormones fluctuate, stress accumulates, and you start noticing thinning, slower growth, or changes in texture.

Viviscal is one of the few supplements specifically designed to support hair growth from within. It contains marine extracts and nutrients that support the hair growth cycle.

After using it for around 6 months, I noticed less shedding and stronger feeling hair. It’s not a miracle overnight fix. But over time, the difference is noticeable.

Supplements are not a replacement for good food, strength training, hydration, or stress management. But they are support systems.

Longevity beauty is about cellular health, muscle health, bone health, hormone awareness, and internal balance. The glow we chase externally often needs to start internally.

And for me, these have been the ones that genuinely made a difference.
