What this is — targeted blend for occasional stress

A targeted blend in a vegetarian capsule that combines a bioactive casein peptide, l-theanine, and vitamin D for support related to occasional stress and sleep.*

Principal ingredients

Each capsule delivers 175 mg Lactium casein hydrolysate (bioactive decapeptide), 50 mg l‑theanine, and 2.5 mcg (100 IU) vitamin D3.

Meaningful formulation

The product uses a concentrated bioactive casein decapeptide (Lactium) plus l‑theanine in a hypoallergenic plant fiber vegetarian capsule.

Delivery and dietary facts

Vegetarian capsule; contains milk; one capsule per day serving size; available as 45 capsules.

Use guidance

Suggested use is one capsule daily between meals; may be taken during the day for stress support or at bedtime for sleep support.

Why It Works

Why it works — bioactive peptide plus calming amino acid

Key ingredient choices and amounts reflect specific research-backed components and nutrient support.*

01

Lactium bioactive peptide

Lactium is a defined casein hydrolysate decapeptide (10‑amino‑acid sequence) provided at 175 mg per capsule.

02

L‑theanine amount

L‑theanine is supplied at 50 mg per capsule, an amount used in studies showing enhanced alpha wave activity in the brain.

03

Vitamin D3 included

Vitamin D3 (cholecalciferol) is provided at 2.5 mcg (100 IU) to support immune and cardiometabolic biomarkers noted in preclinical research.*

04

Combined formulation rationale

The combination pairs a milk‑derived bioactive peptide with l‑theanine and vitamin D3 to address multiple stress‑related domains studied alongside these ingredients.

Sereniten Plus – Unique bioactive casein peptide blend to moderate the effects of occasional stress
Unique bioactive casein peptide blend to moderate the effects of occasional stress Lactium is a unique, clinically researched bioactive casein decapeptide (a polypeptide 10-chain amino acid alpha-1 sequence) developed to target stress-related symptoms. In one 30-day study, subjects supplemented with 150 mg Lactium daily reported statistically significant support for multiple stress-related effects, including digestion, mood, relaxation, sleep, and cardiovascular and cognitive function. In studies where individuals or animals were exposed to mild stressors, supplementation helped moderate healthy heart rate and blood flow, as well as plasma cortisol. Cortisol is released by the adrenal glands during acute and chronic stress. In another study, Lactium promoted the onset of sleep and healthy sleep quality. Healthy sleep quality has been associated with cognitive function and working memory. Sleep also has been tied to metabolic health, including mitochondrial function, visceral fat deposition, alterations in gut barrier function, and changes in gut microbiota. Several studies have shown l-theanine to enhance alpha wave production in the occipital and parietal regions of the brain, helping calm the sympathetic nervous system for a relaxing effect without drowsiness. L-Theanine also helps maintain healthy IgA levels, suggesting support for immune health during occasional stress. Preclinical research suggests that vitamin D plays a role in promoting healthy immune and cardiometabolic biomarkers, and may support normal cortisol production within abdominal adipocytes at the cellular level. Vitamin D may be particularly important for individuals with certain genetic variations.
