Everyone’s adding collagen to their smoothies, coffees, and even their skincare. But is collagen actually the secret to youthful skin and strong joints — or just expensive hype?

In this episode, I break down the real science behind collagen:

What collagen is and why it matters

What peer-reviewed research actually says about skin, joints, and muscle

Which forms work (powder, capsules, shots) and which don’t

What to look for when buying a supplement

How much to take, how to take it, and when it’s worth it

If you’ve ever wondered whether that $2 collagen shot at Joe & The Juice is worth it, this episode will give you the no-BS answer.

I’m Dr. Kerstin Brehm — former heart surgeon, strategist, and founder of The Leadership Clinic. On Have It All, I help ambitious women 40+ cut through the wellness hype and invest in strategies that actually work for longevity and performance.

Magnesium is everywhere right now — from wellness influencers to sleep supplements.

But is it really the *secret longevity hack* it’s made out to be… or just hype?

In this episode of *Have It All* with Dr. Kerstin Brehm (former cardiac surgeon & corporate strategist), we cut through the noise and break down:

✔️ Why magnesium matters (300+ processes in your body daily)

✔️ Signs you may actually be deficient (restless legs, sugar cravings, anxiety & more)

✔️ The 3 BEST types of magnesium (glycinate, threonate, malate) — and what each one does

✔️ The WORST types of magnesium that you should avoid (oxide & citrate)

✔️ How to dose magnesium safely without nasty side effects

Magnesium might be one of the lowest-risk, highest-benefit supplements for high achievers… but only if you choose the right type.
