Your guide to building a smarter, sharper, more resilient brain
Welcome to BrainBodyStack! If you're anything like me, you're here because you're fascinated by how we can support our brains to work better, longer, and with more clarity.
When I first got into nootropics, I was overwhelmed by the sheer number of options. What actually works? What’s safe? What’s worth my money? That’s why I put together this list: a carefully curated top 10 based on both science and real-world experience. These are supplements I’ve either taken myself or researched deeply, and I believe they deserve a spot in any serious brain-health stack.
Let’s dive in.
1. DHA (Docosahexaenoic Acid)
Omega-3 for structure, memory, and long-term brain health.
DHA is one of the foundational fats of the brain, making up about 30% of your brain’s gray matter. It helps keep your neurons flexible and sharp, supporting memory and mental clarity at any age.
Why I recommend it:
- Supports memory, learning, and focus
- Protects against cognitive decline
- Especially important if you don’t eat fatty fish regularly
Suggested Dose:
250–500 mg/day, from high-quality fish oil or algae oil (vegan-friendly)
Tip: Look for products that are third-party tested for heavy metals and purity.
2. Phosphatidylserine
Cell membrane support for better focus and reduced brain fog.
Phosphatidylserine (PS) is a naturally occurring phospholipid found in high concentrations in brain cell membranes. It helps keep your neurons communicating efficiently, and it’s one of the few supplements shown to improve memory in clinical trials.
Why I like it:
- May boost attention, memory recall, and processing speed
- Can help reduce cortisol and mental fatigue
- Gentle and well-tolerated by most
Suggested Dose:
100 mg, 1-2 times daily
3. CDP-Choline (Citicoline)
Fuel for mental energy and neurotransmitter support.
Choline is essential for producing acetylcholine, the neurotransmitter behind learning and memory. CDP-Choline (or Citicoline) is one of the best forms, highly bioavailable and well-studied.
Why I include it:
- Increases focus, mental energy, and motivation
- May support long-term brain health and attention span
- Works well with other nootropics (like racetams or Lion’s Mane)
Suggested Dose:
250–500 mg/day, preferably in the morning
4. Ashwagandha
An adaptogen for calm, clarity, and emotional balance.
This herb is a personal favorite. I started taking it during a high-stress period in my life, and the difference in how I felt, calmer, clearer, less wired, was honestly remarkable.
Why it matters:
- Helps lower cortisol (your stress hormone)
- Supports emotional resilience and sleep quality
- May improve memory and executive function
Suggested Dose:
300–600 mg/day of a standardized extract (e.g. KSM-66 or Sensoril).
5. Creatine
Not just for muscles. Creatine powers your brain, too.
Yes, that’s right, the same supplement bodybuilders swear by is actually fantastic for mental clarity and energy. Your brain uses tons of ATP (energy), and creatine helps you make more of it.
Why it's essential:
- Boosts short-term memory and cognitive performance
- Reduces mental fatigue, especially under stress or sleep deprivation
- Extra beneficial if you eat little to no red meat
Suggested Dose:
3–5 grams/day of creatine monohydrate (mix with water or a smoothie)
6. Ginkgo Biloba
Classic herbal support for blood flow and mental sharpness.
Ginkgo has stood the test of time, and for good reason. By improving circulation to the brain, it supports better nutrient delivery and mental alertness.
Why it earns its spot:
- May enhance focus, recall, and reaction time
- Antioxidant and neuroprotective effects
- Shown to support mood and cognition in older adults
Suggested Dose:
120–240 mg/day of standardized extract (look for 24% flavone glycosides)
7. Methylcobalamin (Vitamin B12 - Active Form)
Essential vitamin for nerve function, energy, and memory.
If you’re low on B12 (and many people unknowingly are), your brain might be running on fumes. Methylcobalamin is the active form your body can use immediately.
Why I take it:
- Supports memory, mental energy, and mood
- Crucial for vegetarians, vegans, or anyone over 50
- Helps maintain healthy myelin (your brain's insulation)
Suggested Dose:
1000 mcg/day, ideally sublingual (under the tongue)
8. L-Theanine
Calm alertness without the crash.
Found in green tea, L-theanine promotes a peaceful, focused state, it’s like meditation in supplement form. I often take it with coffee to smooth out the jitters and stay dialed in.
Why it's a go-to:
- Encourages alpha brain waves (relaxed focus
- Great for anxiety, overthinking, and sleep
- Synergizes beautifully with caffeine
Suggested Dose:
100–200 mg/day (2:1 ratio with caffeine if stacking)
9. Vitamin E (Tocopherols + Tocotrienols)
Antioxidant support for long-term brain protection.
Vitamin E isn’t just one compound, it's a family of antioxidants, and when taken in its full spectrum, it can protect your brain from oxidative stress and age-related decline.
Why it’s essential:
- Helps prevent damage to brain cell membranes
- Supports nerve function and repair
- Works well alongside DHA and other fat-soluble nutrients
Suggested Dose:
100–200 IU/day (look for mixed tocopherols and tocotrienols)
10. Lion’s Mane Mushroom
Mental clarity and brain growth in one.
This is one of the most exciting natural nootropics out there. Lion’s Mane stimulates Nerve Growth Factor (NGF), which plays a key role in forming new brain cells and strengthening existing ones.
Why I love it:
- Improves memory, focus, and cognitive function
- May help with long-term brain regeneration
- Safe and well-tolerated for daily use
Suggested Dose:
500–1000 mg, 1–3 times per day (look for fruiting body extract with >20% beta-glucans)
Final Thoughts
There’s no magic pill for instant genius but with a thoughtful stack, patience, and consistency, you can absolutely sharpen your edge and support your brain for the long haul.
I built this list to be a trustworthy starting point. You don’t need all ten, but choosing the right 3–5 based on your personal goals can make a real difference.
