Let’s Talk About Supplements (Without the Overwhelm)
If you’ve ever walked into the supplement aisle and thought…
“Do I actually need any of this?”
You’re not alone.
Especially after 30 (and even more into your late 30s and 40s), things may start to shift:
Energy isn’t as consistent
Recovery takes longer
Hormones play a bigger role in how you feel day-to-day
And suddenly, supplements can either:
👉 help support your body
👉 or just become expensive clutter in your cabinet
The key is knowing what matters—and what you can do without.
These are the supplements I personally use, plus a few additional high-quality options—and more importantly, how to choose the right ones for YOUR body.
Quick Picks (If You Just Want the Basics)
Best Overall: Magnesium Glycinate
Best for Hormones: Vitamin D3 + K2
Best for Inflammation: Omega-3 Fish Oil
Best for Strength: Creatine
Best for Daily Nutrition: Protein Powder
Best for Stress: Ashwagandha
Best All-in-One: Multivitamin
What to Look for in Supplements (Quick Guide)
Before we jump in, here’s the biggest mistake I see:
👉 Buying low-quality supplements that your body can’t even absorb
Look for:
Minimal fillers
Third-party testing when possible
Forms your body can actually use (this matters a lot)
The 7 Best Supplements for Women Over 35
1. Magnesium Glycinate – Best Overall
👉 Buy Nature's Bounty Magnesium Glycinate here
Why I use it:
This is one of the simplest supplements that makes a noticeable difference.
Supports sleep
Helps with muscle recovery
Calms your nervous system
When to take it:
👉 Evening / before bed (it helps you wind down)
What to look for:
“Glycinate” form (gentler, better absorbed)
Avoid magnesium oxide (poor absorption)
Also consider:
2. Vitamin D3 + K2 – Best for Hormone & Bone Health
👉 Buy Trace Minerals Liquid Ionic Vitamin D3 + K2 here
Why I use it:
Vitamin D is one of the most common deficiencies—and it impacts everything from mood, to immune system, to hormones.
Why K2 matters:
👉 It helps direct calcium to your bones (instead of soft tissues) - don't bother unless it has K2!
What to look for:
D3 (not D2)
Paired with K2 (MK-7 form ideally)
Also consider:
3. Omega-3 Fish Oil – Best for Inflammation & Heart Health
👉 Buy Carlson’s Fish Oil Lemon here
Why I use it:
Supports heart and brain health
Helps reduce inflammation
Great for joints and recovery
What to look for:
High EPA + DHA content (not just “fish oil” amount)
Freshness (NO strong fishy smell = good quality)
👉 If it smells like fish? It’s likely oxidized—skip it.
Also consider:
4. Creatine – Best for Strength, Muscle & Brain Health
Why I use it:
This is one of the most underrated supplements for women.
Improves strength and muscle tone
Supports recovery
Helps maintain lean muscle as you age
Bonus (this is big):
👉 Emerging research shows benefits for brain function and cognitive support
What to look for:
Creatine monohydrate (gold standard)
No unnecessary additives
Unflavored is fine - this mixes well into a pre-workout or shake
5. Protein Powder – Best for Daily Nutrition
👉 Buy Muscle Milk 100% Whey here
Why I use it:
Hitting protein goals consistently is one of the biggest challenges—and this makes it easy.
Supports muscle
Helps metabolism
Keeps you full
Tastes delicious

6. Ashwagandha – Best for Stress & Cortisol
👉 Buy Youtheory Ashwagandha here
Why I use it:
Helps manage stress
Supports sleep and recovery
Can help regulate cortisol
Personally saw a noticeable difference in my stress response
What to look for:
Standardized extract
Reputable brand (quality matters here)
Also consider:
7. Multivitamin – Best All-in-One Support
👉 Buy MaryRuth’s Multivitamin here
Why I use it:
This is your “cover your bases” supplement.
Fills nutrient gaps we don't get from food
Supports overall health
Easy daily habit
What to avoid:
Cheap, low-quality brands (many are poorly absorbed)
Overloaded formulas with unnecessary fillers
Gummy varieties can be loaded with sugar, corn syrup and insufficient quantities of nutrients
👉 Not all multivitamins are created equal—quality matters.
Also consider:
How to Choose What YOU Actually Need
You don’t need all of these.
Start with your goal:
Low energy / poor sleep → Magnesium + Vitamin D
Strength / toning → Creatine + Protein
Stress / overwhelm → Ashwagandha
General health → Multivitamin + Omega-3
FAQs
Do I need to take all of these?
No—start with 1–2 based on your goals if you're overwhelmed. Of course, I think they're all beneficial and this is a basic stack of nutritional supplements.
Are supplements necessary?
They’re not magic—but they can support what you’re already doing. I always recommend getting labs drawn to check for deficiencies.
How long before I see results?
Most take a few weeks of consistency.
Final Thoughts
Supplements aren’t about doing more—they’re about supporting what already works. They're part of a big picture of your whole body health.
Focus on:
Strength training
Eating enough (especially protein)
Consistency
And use supplements to fill the gaps—not replace the basics.
