Phosphatidylserine

What is Phosphatidylserine?

Phosphatidylserine (PS) is a crucial phospholipid that plays a vital role in maintaining cellular function, particularly in the brain [1]. As an essential component of cell membranes, PS is critical for cognitive function, memory, and mood regulation [2].

Phosphatidylserine is a phospholipid, a type of fat molecule that's an essential component of cell membranes. It's particularly concentrated in the brain, where it comprises up to 10% of the total phospholipid content [4].

PS plays several crucial roles in the brain:

• It helps maintain the fluidity and optimal functioning of neural cell membranes
• It's involved in the release and reception of neurotransmitters
• It aids in glucose metabolism in brain cells
• It plays a role in the functioning of various receptor systems [5].

While the body can produce PS, we also obtain it from our diet. However, modern diets often lack sufficient PS, making supplementation a viable option for many people [6].

The Science Behind Phosphatidylserine

Scientific interest in Phosphatidylserine has grown significantly in recent years, with numerous studies investigating its potential cognitive benefits. Here's what current research tells us:

1. Cognitive Function: Studies have shown that PS supplementation can improve various aspects of cognitive function. A review published in Nutrition found that PS can enhance cognitive performance in the elderly [7].
2. Memory Enhancement: Research suggests that PS may improve both short-term and long-term memory. A study in the Journal of Clinical Biochemistry and Nutrition found that PS supplementation improved memory function in elderly individuals [8].
3. Stress Reduction: PS has been shown to potentially reduce stress by lowering cortisol levels. A study in Neuroendocrinology Letters found that PS reduced stress and improved mood in young adults [9].
4. Attention and Focus: Some research indicates that PS may improve attention and focus, particularly in individuals with ADHD. A study in the Journal of Human Nutrition and Dietetics found that PS supplementation improved ADHD symptoms in children [10].
5. Neuroprotection: PS may have neuroprotective properties, potentially helping to slow cognitive decline associated with aging. A review in Nutrition found that PS may help prevent cognitive decline in the elderly [11].

While these findings are promising, it's important to note that research is ongoing, and more large-scale human studies are needed to fully understand Phosphatidylserine's effects.

Benefits of Phosphatidylserine

Phosphatidylserine offers a wide range of potential benefits, primarily for cognitive function:

1. Improved Cognitive Function: Studies suggest that PS supplementation can enhance various aspects of cognitive performance, particularly in older adults [28]. This makes PS a valuable supplement for those looking to support their overall cognitive health.
2. Enhanced Memory: PS may improve both short-term and long-term memory, potentially aiding in learning and recall [29]. This benefit could be particularly appealing for students or professionals looking to boost their memory performance.
3. Stress Reduction: PS has been shown to potentially lower cortisol levels, which may help reduce stress and improve mood [30]. This dual cognitive and mood-enhancing potential sets PS apart from many other nootropics.
4. Improved Attention and Focus: Some research indicates that PS may enhance attention and focus, which could be particularly beneficial for individuals with ADHD [31]. This potential to improve concentration makes PS an interesting supplement for both work and study environments.
5. Neuroprotection: PS may have neuroprotective properties, potentially helping to slow cognitive decline associated with aging [32]. This long-term brain health benefit is particularly appealing for those concerned about maintaining cognitive function as they age.
6. Support for Brain Cell Membranes: As a key component of cell membranes, PS supports the overall health and function of brain cells [33]. This fundamental role in brain health sets PS apart from many other cognitive enhancers.
7. Potential Athletic Performance Benefits: Some studies suggest PS may help reduce exercise-induced stress and support athletic performance [34]. This potential benefit extends the appeal of PS beyond just cognitive enhancement.

Remember, while these benefits are promising, individual experiences may vary. Consistent use is typically necessary to experience the full range of Phosphatidylserine's effects.

Dosage and Usage

The effective dosage of Phosphatidylserine can vary depending on the specific purpose and individual factors. Many studies showing positive effects of PS used doses ranging from 100mg to 400mg per day. For example, a study published in the Journal of Clinical Biochemistry and Nutrition used 100mg of PS daily and found improvements in memory function in elderly individuals [17].

For general cognitive support, a typical daily dose is 100-300mg of Phosphatidylserine. This dosage aligns with the effective range seen in studies, providing significant benefits while still ensuring safety for long-term use [18].

Our Approach to Dosing

We select exact milligram dosages based on scientific studies associated with the specific ingredient. These dosages align the "minimum viable dose" to see positive associated benefits based on the research.

These MVD also will be higher than other competitors, but importantly lower than the specific studies references for one key reason. This reason is that many scientific studies look at short term data and results, as such they focus on higher end dosages to speed up the associated benefits (or negative side effects) of a specific ingredient. This is perfect for clinical scientific studies, but for everyday use, dosages should be reduced as we're looking for a longer  term focus and approach on "focusing for decades not minutes". As a result, each individual ingredient has the minimum effective dosage, without overdoing any one specific ingredient when taken daily for an extended period of time.

When considering Phosphatidylserine supplementation, it's crucial to understand its pharmacokinetics:

• When supplemented, PS is incorporated into cell membranes throughout the body, particularly in the brain.
• The turnover rate of PS in brain cell membranes is relatively slow, with effects potentially lasting for several weeks after supplementation [26].
• Studies have shown that it can take several weeks of consistent supplementation for PS levels to build up significantly in brain tissue and for cognitive effects to become noticeable [27].

For optimal results:

1. Daily dosing is recommended to maintain consistent levels of PS in the body.
2. Effects may not be noticeable immediately, but should build up over several weeks of consistent use.
3. Long-term, consistent use is likely necessary for sustained cognitive benefits.

Phosphatidylserine Supplement Variations

When choosing a Phosphatidylserine supplement, consider the following factors:

1. Source: Look for soy-derived PS, which has been shown to have excellent bioavailability and is more sustainable than bovine-derived alternatives.
2. Dosage: Choose a product that provides an effective dose, typically 100-300mg per serving.
3. Purity: Opt for products from reputable manufacturers that undergo third-party testing for purity and potency.
4. Form: PS supplements are available in various forms, including capsules, softgels, and powders. Capsules are often preferred for their convenience and precise dosing.
5. Additional Ingredients: Some formulations combine PS with other cognitive-enhancing compounds. Consider your overall supplementation goals when choosing a product.
6. Allergen Information: While soy-derived PS is typically free from soy proteins, check the label for potential allergens if you have any food sensitivities.
7. Brand Reputation: Choose a brand known for quality and transparency in their manufacturing processes.
