What Is Phosphatidylserine?

Phosphatidylserine is an important phospholipid compound. It is widely found in animal tissues and plant seeds. It is involved in a variety of physiological functions as an important component of human cell membranes. In particular, Phosphatidylserine bulk is important for brain health and cognitive function. The sources of dietary phosphatidylserine and its recommended intake are described in detail below.

Sources of Phosphatidylserine

Phosphatidylserine can be obtained from a variety of animal and plant sources. Guanjie Biotech produces phosphatidylserine bulk from soybeans and sunflower. Here's a look at what sources it comes from.

1. Animal sources

Animal offal, such as bovine and porcine brains are rich sources of phosphatidylserine. These foods are rich in PS. but are problematic due to their high-fat content as well as cholesterol intake. It is more difficult to obtain phosphatidylserine directly through the consumption of these foods in the daily diet. In addition, some fish, such as salmon and tuna also contain some amount of phosphatidylserine. They are better sources of animal foods.

 

2. Plant sources

- Soybeans:

Soya is one of the major sources of plant-based phosphatidylserine. High-purity phosphatidylserine can be obtained through the extraction and processing of soybean phospholipids. Soya-sourced PS has the advantages of a plant source. It is suitable for vegetarians and people who are sensitive to animal sources.

- Sunflower seeds:

Sunflower seeds are rich in phospholipids. It also contains a certain amount of phosphatidylserine among them. Sunflower seeds phosphatidylserine can be obtained from it by cold pressing or chemical extraction.

 

- White Kidney Bean:

Legumes like white kidney beans also contain some amount of phosphatidylserine. However, its content is low.

Guanjie Biotech produces pure phosphatidylserine bulk which is from soybean or sunflower seeds. And it can be purified to ensure high-purity phosphatidylserine content. We produce phosphatidylserine powder bulk, phosphatidylserine granular phosphatidylserine liquid form. The advantage of PS brain supplement over dietary sources is that intake can be more precisely controlled.

 

Recommended Intake

The recommended intake of phosphatidylserine varies depending on an individual's age, physical condition and needs. Recommended amounts vary between studies and health guidelines. The following are recommendations for phosphatidylserine bulk intake.

1. Daily Requirements for Adults

• General Healthy Population:

For the general healthy population, a daily intake of 100-300 mg of bulk phosphatidylserine is recommended. This maintains brain function and neurological health. This dose can usually be met with a PS-rich diet.

• Cognitive Function Support:

Studies have shown that a daily intake of 200-400 mg of PS can help improve memory, concentration, and other cognitive functions. It is especially beneficial for middle-aged and older populations. For adults with mild memory loss or concentration difficulties, a PS supplement of 300 mg per day may be an appropriate choice.

 

2. Elderly and Cognitively Declining Populations

• Older adults:

As we age, phosphatidylserine levels in the brain decrease. They are prone to memory and cognitive decline. For the elderly, a daily intake of 300-500 mg of Phosphatidylserine bulk is recommended. This may help to slow down cognitive decline. This dosage has been shown in several clinical studies to improve memory, concentration, and language skills in older adults.

• Alzheimer's patients:

For patients with Alzheimer's disease and other types of cognitive impairment, some studies recommend 600-800 mg of soy phosphatidylserine powder per day. But take it in multiple doses to better promote absorption and utilization. Although PS does not completely cure these diseases, it is used as an adjunctive therapy. It helps to improve the cognitive status and quality of life of patients.

 

3. Athletes and high-intensity brain users

• Athletes:

Pure Phosphatidylserine also has a role in exercise recovery. Especially after high-intensity exercise. This reduces the secretion of exercise-induced stress hormones such as cortisol. For athletes who need to speed up recovery or reduce exercise stress, a daily intake of 200-400 mg of phosphatidylserine bulk is recommended.

• Students and high-intensity brain users:

For students who need to maintain concentration and memory for long periods or those who are engaged in high-intensity brain work, a daily intake of 200-300 mg of PS can help enhance cognitive performance.

 

4. Children and adolescents

Phosphatidylserine bulk also promotes memory, concentration and learning ability in children and adolescents. However, the use of PS supplements for this age group requires more caution.

• Children 6 years and older:

A daily intake of 50-100 mg of PS can promote memory and attention while ensuring safety.

• Adolescents 12 years and older:

This can be appropriately increased to 200 mg per day as needed.

 

Safety:

Most studies have shown that phosphatidylserine bulk is safe at 300-400 mg/day doses for 6 months. However, long-term ultra-high dose use (over 600 mg/day) should be done under medical supervision to avoid potential side effects.
