Phosphatidylserine (PS) from Lecithin (Sunflower) (Helianthus annuus) Seed Oil

100 mg

†

The product is found useful for the following medical conditions

We evaluated the effects of phosphatidylserine (PS)-containing liposomes on high cholesterol and atherosclerosis. In our study with rabbits on a high-fat diet, we administered PS liposomes and found notable reductions in harmful cholesterol levels and plaque size compared to controls.

Both PS and atorvastatin-loaded PS liposomes effectively lowered LDL and total cholesterol without impacting other lipid levels. While we observed significant improvements in plaque characteristics and intima-media thickness, other factors like triglycerides and HDL remained unchanged.

Overall, PS liposomes appear promising for improving lipid profiles and aiding in plaque regression.

An excellent working drug! Phosphatidylserine enhances mental concentration, memory, mood, and sleep. I take one capsule daily with ubiquinone and benfotiamine, along with amino acids and B vitamins to restore my nervous system. They are small, soft capsules, easy to swallow. The drug clearly works; my sleep quality improved significantly. Previously, I needed 8-9 hours for a good night's sleep, but now 6-7 hours suffices. I'm very pleased with the result and will continue purchasing it. This product truly deserves attention. Stay healthy!

Significant brain improvement

PS 100, combined with Acetyl-L-Carnitine, has had a dramatic effect on my mind following my major operation and stroke. The painkillers affected my brain negatively, yet PS 100 has restored my mental sharpness and abilities. I believe my brain capacity plummeted to around 50%, but it's now back up to 90%. With my IQ of 173, the decline in my cognitive function was stark, just as was the improvement after I took the product for six months after feeling despondent. I highly recommend PS 100 to everyone.

A good product with small capsules that my 5-year-old with ASD takes. The combination works very effectively, leading to improved behaviour, attentiveness, and completion of assignments from his teacher. The doctor has recommended a course of four to consolidate these results, so I will continue purchasing it.

Phosphatidylserine improves ADHD symptoms

Hirayama S, Terasawa K, Rabeler R, Hirayama T, Inoue T, et al. The effect of phosphatidylserine administration on memory and symptoms of attention-deficit hyperactivity disorder: a randomised, double-blind, placebo-controlled clinical trial. J Hum Nutr Diet. 2014;27 Suppl 2:284. doi:10.1111/jhn.12090

We examined the effects of soy-derived phosphatidylserine (PS) on attention-deficit hyperactivity disorder (ADHD) in children aged 4-14. In this randomized, double-blind study, 36 children either received 200 mg of PS or a placebo for 2 months.

The results were promising, as PS showed significant improvements in ADHD symptoms and short-term auditory memory. However, not all measurements indicated benefits, and the placebo group didn't show notable changes. Overall, PS appears to be a well-tolerated option for enhancing mental performance in children with ADHD.

The softgel was more effective than capsules for me. With ADHD and depression, I used to be stressed and unmotivated, but after taking it, I felt a calming effect. It's like a lie how my frustration lessened, and now I feel positive at work. I can't do without it!

I have struggled with sleep disturbances all my life, but I discovered that this product helps by reducing adrenal activity. I take 4-5 tablets daily before bed. My sleep disturbances have finally improved, which high-dose melatonin could not resolve. The phosphatidylserine quality is good; I constantly reorder due to its effectiveness.

Anxiety details

Phosphatidylserine lowers stress responses

Hellhammer J, Fries E, Buss C, Engert V, Tuch A, et al. Effects of soy lecithin phosphatidic acid and phosphatidylserine complex (PAS) on the endocrine and psychological responses to mental stress. Stress. 2004;7:119.

In our study, we looked at how phosphatidylserine supplementation affects mood and stress responses during an anxiety-inducing situation. Participants were divided into four groups, receiving different doses of phosphatidylserine before facing a mental stress test.

We found that the group receiving 400 mg of phosphatidylserine experienced lower stress hormone levels and reported feeling less distressed. However, larger doses did not bring the same benefits, indicating that the 400 mg dosage might be key in alleviating anxiety during stress.

These findings suggest that phosphatidylserine could be a promising option for managing stress-related issues.

Effective immediately, one tablet is great for anxiety feelings before stressful encounters. It alleviates waves of anger and sadness. I tried both capsule and tablet forms and found both work equally well. Although priced high, I’m concerned about low-cost options affecting its effectiveness.

Phosphatidylserine liposomes show promise

We investigated the use of phosphatidylserine (PS) liposomes encapsulating specific autoantigens as a treatment for various autoimmune diseases. These liposomes can effectively be tailored for different conditions by simply changing the autoantigen inside them.

Once administered, they target organs and engage with immune cells, promoting tolerance and reducing the immune response associated with diseases like rheumatoid arthritis and myasthenia gravis. Our findings suggest a promising method that is both safe and potentially long-lasting for addressing autoimmune disorders.

Without exaggeration, phosphatidylserine is my best find among numerous dietary supplements. The small capsules are straightforward to swallow, and after taking one daily for a month, I began to notice improvements in my cognitive function. The fog in my mind has cleared, enhancing my focus, attention, and even motivation. Unlike other supplements, phosphatidylserine has truly exceeded my expectations.

Now I can move smoothly! Initially, I only wanted to read this review, and a week in, I hadn’t noticed much effect. However, my head and body fatigue after work has improved considerably! Iron supplements helped my chronic fatigue, and now I feel I can switch my moods and move more quickly. I can cook and clean right after getting home, which is miraculous. It’s a bit pricey for me, so I take it twice daily, but I’ll continue as long as it feels beneficial. It may help those struggling with motivation.

Useful drug for improving brain function. The packaging of gel capsules is comfortable for taking. I haven't noticed a difference between gel and powder forms, as both seem effective. My mum can only take gel capsules due to gastrointestinal issues. Phosphatidylserine helps delay age-related cognitive impairment, including memory and concentration difficulties. I noticed improvements in memory, concentration, and motivation after just 30 days with one gel per day, which has eased formulating my thoughts and learning foreign languages. This is excellent supportive therapy.

Antidepressive effects observed in study

Castilho JC, Perry JC, Andreatini R, Vital MA. Phosphatidylserine: an antidepressive or a cognitive enhancer?. Prog Neuropsychopharmacol Biol Psychiatry. 2004;28:731.

We investigated whether phosphatidylserine (BC-PS) could effectively treat depression and enhance cognitive function. In our study, rats took BC-PS in various doses and were compared to a control group. We observed that BC-PS significantly reduced how long the rats remained immobile in a stress test, suggesting an antidepressive effect.

However, when it came to improving memory in different maze tasks, BC-PS showed no significant benefits compared to the control group. This indicates that while BC-PS may help with depression, it doesn't appear to boost cognitive abilities.

No soy from Jerow! The phosphatidylserine is sourced from sunflower, which is a significant advantage. It's beneficial for the nervous system, aids in seasonal depression, lowers cortisol levels and enhances cognitive functions like thinking and memory. Overall, all the supplements from Jerow that I ordered here are effective!

We explored how phosphatidylserine (PS) affects memory in patients and rats with Alzheimer's disease. The study involved 57 patients split into control and treatment groups, while AD rats were given various doses of PS for 12 weeks.

Results showed that patients and treated rats improved memory scores and brain health significantly. The higher dose of PS was particularly effective in enhancing memory and reducing harmful brain inflammation.

Overall, phosphatidylserine appears promising as a treatment to boost memory function in Alzheimer's patients.
