Seriphos® Phosphorylated Serine by InterPlexus

Seriphos® - Adaptogen and Adrenal Support, by InterPlexus, contains pure phosphorylated serine, ethanolamide (phospholipids), magnesium and calcium. These substances form metabolic building blocks for the production of phospholipids in cell membranes, such as phosphatidylserine and phosphatidylethanolamine. The synergy of these ingredients ensures optimal absorption and bioavailability within the body. Magnesium contributes to a clear mind and helps fight fatigue while benefiting the nervous system. Calcium contributes to normal neurotransmission and nerve functions. Seriphos® is a powerful adaptogen.

Phosphorylated Serine vs Phosphatidylserine

The uptake of phosphorylated serine is not dependent on enzymes in the gastrointestinal tract. It is therefore effective and easily absorbable. Sufficient enzymes in the stomach are needed for the absorption of phosphatidylserine. Phosphorylated serine is the active form of serine which the body can use directly. Most phosphatidylserine products provide approximately 20 mg of activated serine per capsule. Seriphos® delivers 90 mg of active serine per capsule.

Phosphorylated serine acts as an adaptogen

Adaptogens are substances known for their ability to effectively influence homeostasis (overall physio-chemical balance). Adaptogens have a broad range of effects in the body and can be active wherever needed. The addition to Seriphos® of magnesium and calcium ensures that these substances benefit the normal functioning of the mind and nervous system.

What is L-Serine?

Serine is a non-essential amino acid invariably produced from other amino acids, especially glycine. Although the amino acid was discovered over 150 years ago, knowledge about it remains quite limited. However, key functions of L-serine have been identified. L-serine often acts as a precursor to the body's own substances or as a building block for cells and fatty acids. A good example of this is the formation of phosphatidylserine from serine and glycerol.

What is Ethanolamine?

Ethanolamine is both a primary amine compound and a primary alcohol compound. The biological role of ethanolamine in the body is intriguing and well-documented. Ethanolamine is essential for life and is present in every cell of the human body, especially as the core group of phosphoethanolamine and other fats. It is also present, in varying amounts, throughout the body as a free ethanolamine. Mammals cannot produce ethanolamine themselves. The body is dependent on dietary intake of ethanolamine.

When to take

Just one Seriphos® capsule per day is sufficient. It is best to take Seriphos® 15 minutes before a meal. If you want to benefit a little extra from Seriphos®, such as in case of fatigue, take the capsule right before dinner. Seriphos® contains strictly pure and highly bioavailable ingredients.
