Phosphatidylserine 60 Caps Thorne

Thorne Phosphatidylserine 60 Caps – Thorne | Cognitive Support, Memory & Stress

Thorne Phosphatidylserine 60 Caps is a phospholipid supplement with 100 mg of isolated PS per capsule, designed for adults who want to support cognitive function, memory, focus, and cortisol balance. It can be beneficial for those who want to support their brain during aging, in periods of intense stress, or who need to maintain high cognitive performance.

Phosphatidylserine (PS) is the main phospholipid found in the nerve cell membranes of the brain — essential for communication between neurons, cellular energy metabolism, and the normal production of neurotransmitters. With aging, PS levels in brain membranes tend to decrease, which can affect memory, processing speed, and stress response. Thorne's Phosphatidylserine (Iso-Phos) provides 100 mg of isolated PS per capsule, in a clean formulation of recognized clinical quality. It can support cognitive function, memory, focus, and cortisol modulation in stressful situations. Gluten-free, lactose-free, with a vegetable capsule, and produced in the USA according to Thorne standards.

Isolated Phosphatidylserine (PS, 100 mg per capsule) is the most abundant phospholipid in the nerve cell membranes of the cerebral cortex — the main component that determines the fluidity, permeability, and functionality of neuronal membranes. PS plays a central role in multiple brain processes: it facilitates communication between neurons, supports the production and release of neurotransmitters (including acetylcholine, essential for memory and learning), and participates in cerebral glucose metabolism.

PS also has an established relationship with the stress response: it can help modulate the activity of the hypothalamus-pituitary-adrenal (HPA) axis, contributing to a more balanced production of cortisol in situations of physical or mental stress. This property makes it relevant for both cognitive well-being and for athletes and people with physically demanding lifestyles.

Thorne's Phosphatidylserine is derived from soy — the most common and studied source of this phospholipid in supplementation. Although it contains a soy derivative (phospholipid), it does not contain soy protein.

The excipients — microcrystalline cellulose, leucine, silicon dioxide, and hypromellose (vegetable capsule) — are commonly used in pharmaceutical-grade formulations.

Points to consider

• Contains soy derivative (isolated phosphatidylserine from soy lecithin — no soy protein). Individuals with confirmed soy allergy should consult a healthcare professional before use.
• Phosphatidylserine may have a slight anticoagulant effect — use with caution or avoid in individuals taking anticoagulants (warfarin, heparin, antiplatelets) without medical guidance.
• Possible interaction with acetylcholinesterase inhibitors or cholinergic medication (such as donepezil) — the effect may be additive. Consult your treating physician before starting.

✅ May contribute to cognitive function and memory in situations of mental fatigue
✅ Supports brain health and adaptive response to stress
✅ Contains phosphatidylserine – an essential nutrient for neuronal cell membranes
✅ May be useful during periods of high mental load, aging, or cognitive fatigue
✅ Free from gluten, soy, dairy, and artificial additives
✅ Pure, safe, and highly absorbable formula

Thorne's formula is plant-based, highly purified, and free from soy derivatives – an important differentiator for individuals with sensitivities.

How to Use: 1 Capsule daily or as directed by a healthcare professional.

Can people with cognitive decline, "brain fog", or memory concerns benefit from Phosphatidylserine?

PS is the go-to phospholipid for cognitive well-being, especially in the context of brain aging. Individuals experiencing "brain fog," frequent forgetfulness, or those wishing to support memory and focus, may consider this supplement as part of an integrated approach to cognitive well-being — always with medical supervision when symptoms are clinically significant.

Can people with chronic stress, high cortisol or adrenal exhaustion benefit?

PS can support HPA axis and cortisol modulation, which is relevant for those with chronically elevated stress levels. Anyone who suspects adrenal fatigue or persistently high cortisol should supplement with medical evaluation and hormonal analyses.

Can people with Alzheimer's disease or dementia benefit?

PS has been studied in contexts of cognitive well-being in ageing. Those diagnosed with dementia or Alzheimer's disease must consult a neurologist before starting any supplementation, given the potential for interaction with cholinergic medication usually prescribed in these situations.
