The GZ HAOYUAN Citicoline 500 mg supplement is a thoughtfully designed nootropic formula that goes well beyond basic choline capsules. By pairing Citicoline (CDP Choline) with Phosphatidylserine, it targets the cellular level of brain function, supporting memory retention, focus, and overall cognitive wellness. This makes it a strong option for students, professionals, or anyone who wants daily mental sharpness and long-term brain health.
What sets this product apart is its complete approach to brain and eye nutrition. Alongside the core cognitive ingredients, it includes Lutein, Zeaxanthin, and Astaxanthin, which are known for supporting visual health. This dual-action formula is ideal for people who spend long hours in front of screens and want to protect both their mind and eyes in one convenient daily capsule.
The inclusion of highly bioavailable nutrients, such as Benfotiamine, Riboflavin-5-Phosphate, P-5-P, Methylcobalamin, and Methyl Folate, shows a commitment to quality.

Buying Guide: How to Choose Between Phosphatidylserine and Citicoline
Before you tap “add to cart,” you need a clear picture of what makes these two compounds unique and how they complement each other. The right choice depends on your specific memory challenges, lifestyle, and how your body responds to different forms of supplementation. Below we break down the four most important factors to weigh.
1. Ingredient Synergy: PS and Citicoline Together
Phosphatidylserine is a phospholipid that makes up part of your cell membranes, especially in the brain. It supports neuronal signaling and helps regulate cortisol, a stress hormone that can impair memory. Citicoline, on the other hand, is a nucleotide that provides choline, a building block for acetylcholine, a neurotransmitter critical for learning and memory. When combined, they target different pathways: PS stabilizes cell membranes, while citicoline boosts neurotransmitter production.
Many premium brain supplements now combine both. For example, the GZ HAOYUAN Citicoline 500 mg includes 500mg citicoline and 300mg PS, offering a dual-action approach. If you’re looking for a all-in-one solution, a combination might be more convenient. But if you prefer to fine-tune your doses separately, individual products give you more control. Check out our comparison of phosphatidylserine vs Omega-3 to see how these fats interact.
2. Form and Delivery: Capsules, Gummies, or Drops
The format matters more than you think. Capsules are easy to swallow and typically offer precise dosages, like Double Wood’s Phosphatidylserine 300mg. Gummies, such as NEVISS Citicoline 1000mg & Phosphatidylserine, are great for people who dislike pills, but they often contain added sweeteners (though NEVISS uses monk fruit and stevia). Liquid drops, like NATISLAND’s Citicoline 1000mg + Phosphatidylserine, are ideal for kids or anyone who needs flexible dosing.
Consider your routine. If you travel a lot, capsules are more portable. If you have a picky child, drops mixed into juice might be the solution. Gummies can be a delightful daily ritual. Just watch out for sugar content and choose a product that aligns with your dietary preferences, whether vegan, gluten-free, or allergen-friendly.
3. Dosage and Potency: What to Look For
Clinical studies often use 300mg of phosphatidylserine daily for memory support. Citicoline research frequently employs doses around 250 to 500mg, though some formulas go higher. The NEVISS gummies pack 1000mg of citicoline per serving, which is generous. GZ HAOYUAN offers 500mg, a solid mid-range dose. For PS, Double Wood’s 300mg is the standard effective amount. Always check the label for “active” forms like CDP-choline or Cognizin, which are better absorbed.
Be cautious of proprietary blends that hide individual ingredient amounts. Transparency is key. Also, look for products that include complementary nutrients like B vitamins, which are essential for neurotransmitter synthesis. The best memory supplements on Amazon often combine these for a synergistic effect, as we’ve seen in our top brain health supplements roundup.
4. Purity and Sourcing: Quality Matters
Your brain deserves the best. Look for supplements that are non-GMO, gluten-free, and free from artificial additives. Double Wood explicitly states its PS is manufactured in the USA from globally sourced ingredients. NEVISS emphasizes its gummies are vegan and allergen-free. NATISLAND uses organic lion’s mane and vegan algal oil. These details reflect a commitment to quality. Third-party certification, such as NSF or GMP, adds another layer of confidence.
When in doubt, research the brand’s reputation. Avoid products with vague labeling or fillers. You can also consult professional reviews, like our phosphatidylserine vs ginkgo comparison, to see how different nootropics stack up. Remember, a higher price doesn’t always mean higher purity, but rock-bottom prices often signal lower-grade ingredients.
Final Thoughts
If you’re looking for a straightforward, no-nonsense PS supplement that hits the clinically studied dose, Phosphatidylserine 300mg, Memory from Double Wood is a reliable choice. For those who want the convenience of both nutrients in one, the GZ HAOYUAN Citicoline 500 mg offers a balanced combination of citicoline and PS, plus additional brain-boosting vitamins. Whichever you pick, consistency is key, so choose a product you’ll actually take daily.
Frequently Asked Questions
Can I take phosphatidylserine and citicoline together?
Yes, they work synergistically. Many supplements combine both to support different aspects of memory. For example, citicoline boosts acetylcholine production, while PS maintains cell membrane integrity. Together, they may offer more comprehensive cognitive support than either alone.
How long does it take to see memory improvements?
Results vary, but some people notice improved focus within a few weeks. For more significant memory changes, consistent use over 8 to 12 weeks is typically recommended. Think of it as nourishing your brain daily, not as a quick fix.
Are there any side effects?
Both ingredients are generally well-tolerated. Some people might experience mild digestive upset or insomnia if taken late in the day. Always start with a lower dose to assess tolerance, and consult your healthcare provider if you have underlying conditions.
Which is better for aging memory: PS or citicoline?
Research suggests both help, but they target different mechanisms. PS may help reduce stress-related cognitive decline, while citicoline supports neurotransmitter production. A combination could be most beneficial for age-related memory concerns. For more insights, check our phosphatidylserine vs acetyl L-carnitine piece.
