Once you hit your 40s, everything shifts—hormones, metabolism, muscle mass, sleep, energy, even how your brain feels day to day.
This is where supplementation stops being “optional” and becomes strategic.
These are my non-negotiables—the supplements I personally recommend for women 40+ to support bone, brain, muscle, metabolism, and long-term health. We get bogged down with so many recommendations on Instagram, TikTok and Facebook that I wanted to do a deep dive into the literature and put this essential list together. It is what I do and what I recommend!
1. Vitamin D + K2 (Non-Negotiable for Bone + Longevity)
If I had to pick one foundational supplement, this is it.
Why it matters:
- Supports bone density and osteoporosis prevention
- Improves calcium absorption
- Helps direct calcium into bone and away from arteries
- Supports immune function and mood
Vitamin D and K2 work together—D helps absorb calcium, and K2 ensures it goes to the right place.
My favorite:
- The Pause Life Vitamin D3 + K2

2. Omega-3 Fatty Acids (Brain, Heart, Inflammation)
Omega-3s are one of the most powerful anti-inflammatory tools we have.
Benefits:
- Supports brain health and cognition
- Improves mood and focus
- Reduces joint pain and inflammation
- Supports cardiovascular health
- Helps with skin and hormone balance
My favorite:
- The Pause Life Omega-3 (contains D3 and K2!)

3. Magnesium (Magnesium 5x Complex — Take at Night)
Magnesium is one of the most common deficiencies I see.
Benefits:
- Improves sleep quality
- Reduces anxiety and stress
- Helps with muscle relaxation
- Supports metabolism and blood sugar
- May improve mood and headaches
My recommendation:
- Magnesium 5x complex

Take this at night—this is where you’ll feel the biggest difference.
4. Creatine (5–10 g Daily — Morning)
Creatine is one of the most important supplements for women over 40.
Benefits:
- Preserves muscle mass and strength
- Supports brain energy and cognition
- Improves exercise performance
- Helps with fatigue and mental clarity
My recommendation:
- Creatine monohydrate (clean, third-party tested)
👉 https://www.thorne.com/products/dp/creatine - Dose: 5–10 grams daily
- Timing: Morning
5. Fiber (25g Daily — Essential, Not Optional)
This is one of the most overlooked “supplements.”
Benefits:
- Supports gut health
- Improves cholesterol and heart health
- Helps regulate blood sugar
- Supports hormone metabolism
- Aids in weight management

Food-based:
- Chia seeds
- Flaxseed

6. SPF (Yes, I Consider This a Daily “Supplement”)
This may surprise you—but sunscreen is one of the most important daily health tools.
Why it matters:
- Prevents skin cancer
- Prevents collagen breakdown and aging
- Protects against UV-induced inflammation and DNA damage
My favorite:
- European La Roche-Posay sunscreen
👉 https://www.caretobeauty.com/us/la-roche-posay-anthelios
Use it every single day—even indoors.
7. Turmeric (Optional — With Caution)
Turmeric (curcumin) is a powerful anti-inflammatory and antioxidant.
Benefits:
- Supports joint health
- Reduces inflammation
- May support cardiovascular health
⚠️ Use caution if you have a history of liver disease
Always ensure your supplements are third-party tested.
Example:
- The Pause Life Turmeric (Dr. Mary Claire Haver)

8. Daily Oral Antioxidant (Underrated but Important)
Oxidative stress increases with age and contributes to:
- Aging
- Inflammation
- Chronic disease
Options:
- Vitamin C
👉 https://www.thorne.com/products/dp/vitamin-c - Glutathione
👉 https://www.thorne.com/products/dp/glutathione-sr - CoQ10
👉 https://www.thorne.com/products/dp/q-best-100 - Resveratrol
👉 https://www.amazon.com/dp/B0ResveratrolExample
These support:
- Cellular health
- Mitochondrial function
- Skin and immune health
Other supplements to consider include a daily probiotic for gut and brain health. Additionally, if you suffer from recurrent UTI’s you can use products such as Uqora or combinations of D-Mannose, Cranberry and Vitamin C to help prevent UTI’s. I take both of these myself!
Supplement Quality Matters
This is critical.
- Supplements are not regulated like medications
- Always choose:
- Third-party tested products (NSF, USP, Informed Choice)
- Reputable brands
- Clean formulations (brands such as Nature Valley, Thorne, Biote, The Pause Life)
Timing Summary (Simple + Practical)
Morning:

Night:
