The Non-Negotiable Supplement Stack for Every Client Over 40

Jay Harris • November 25, 2025

What we actually put our 40-, 50-, and 60-year-old clients on the very first week

If you’re over 40 and you’re still “winging it” with supplements (or worse… taking none), you’re leaving muscle, energy, hormones, and recovery on the table.

After coaching hundreds of Calgary executives, entrepreneurs, and high-performers in their 40s, 50s, and 60s, we’ve refined the shortest, most evidence-based stack that actually moves the needle — no fluff, no $19.99 gummy marketing.

These are the exact bottles you’ll find in every one of our over-40 clients’ kitchens (and yes, Kevin Smith and I personally take every single one).

1. High-Potency Vitamin D3 + K2 – 5,000 IU daily (with food)

Calgary reality: 9 months of the year we live like vampires.

95 % of our new clients test deficient or insufficient (<75 nmol/L).

Low D tanks testosterone, mood, immune function, and bone density.

Take 5,000 IU D3 + 100–200 mcg K2 (MK-7 form) every day with your biggest meal. We re-test in 8–12 weeks and adjust.


2. Magnesium Breakthrough (or Glycinate/Threonate) – 400–600 mg elemental magnesium nightly

Sleep, stress, cramps, blood pressure, insulin sensitivity — magnesium touches all of them.

After 40 your ability to absorb it from food drops, and alcohol + stress deplete it faster.

Take it 60–90 min before bed. Clients routinely report the deepest sleep they’ve had in years within 7–10 days.


3. Pharmaceutical-Grade Fish Oil – Minimum 2 g combined EPA + DHA daily

Inflammation is the silent killer of gains, hormones, and recovery after 40.

Most cheap fish oils are rancid or under-dosed.

We use a high-potency triglyceride-form oil (look for IFOS 5-star rating). Bonus: it dramatically improves mood and focus — clients notice this in 2–3 weeks.


4. Creatine Monohydrate – 10 g daily (yes, women too)

The most researched supplement on earth.

After 40 you lose ~8 % of muscle per decade. Creatine slows that, increases strength 10–20 %, and improves brain function.

Zero loading phase needed — just 5 g in your post-workout shake or morning coffee forever.


5. Quality Protein Powder – 30–50 g per shake, 1–2× daily

Sarcopenia (age-related muscle loss) accelerates after 40.

You now need ~2 g protein per kg bodyweight just to maintain muscle — most busy professionals fall way short.

A clean whey isolate (or beef isolate if dairy-sensitive) is the easiest insurance policy.


6. Bonus (but basically mandatory for our crew)

  • Tongkat Ali + Fadogia Agrestis cycling (for natural testosterone & libido support — Our Coaches personally swear by this combo)
  • NMN or NR (1 g/day) – the only longevity compound that consistently improves our clients’ energy and recovery
  • Ubiquinol (CoQ10) 200 mg – especially if you’re on a statin or over 50


What we DON’T waste money on

  • Multivitamins (food + the stack above covers you)
  • BCAAs (you’re already getting plenty from protein)
  • Collagen (save your money unless you have joint pain)
  • “Test boosters” with proprietary blends and pixie-dusted ingredients


Bottom line: If you’re over 40 and you’re only eating well and training hard but skipping this stack, you’re fighting with one hand tied behind your back.


Want us to build you the exact brands, dosages, and timing we use with our private clients (the same ones that helped a 52-year-old CEO drop 38 lbs and get his testosterone from 9 to 28 nmol/L in 5 months)?


Contact us and we’ll send you the full Over-40 Protocol + current bloodwork discounts.


Age is just a number — but only if you give your body the raw materials it’s screaming for.
