Best remedy for evening cortisol and anxiety
Verified Purchase
Working phosphorylated serine is a rare form, it really helps to reduce cortisol levels and turn off the “internal overheating” in the evening. I started sleeping deeper, falling asleep faster, and not waking up at night. The anxiety level has decreased, and my energy is not “crumpled” in the morning. The quality is excellent, the capsules are standard, without any aftertaste. I take it 1–2 hours before bedtime. It is suitable for those who “burn out” in the evening or cannot calm down before bedtime. Of all the anticortisol supplements, Seriphos works the best.

Good complex
Verified Purchase
A good complex to help the body cope with stress and reduce the burden on the adrenal glands. From the trusted brand InterPlexus. I take one capsule 15-30 minutes before meals for two months. I've become more resilient to stress, feel more balanced, and sleep more peacefully. The capsules are small and easy to swallow.

High-Quality Supplement for Relaxation and Balance
Verified Purchase
The InterPlexus Seriphos™ capsules have been a dependable part of my supplement routine. I appreciate that they come in vegetarian capsules and use a thoughtful formula designed to support a calm, balanced feeling during stressful times. The capsules are easy to swallow and gentle on the stomach. I also like that the bottle lasts a long time since only a small serving is needed. The quality is consistent, and the brand has a solid reputation for producing well-formulated products. Overall, this is a premium supplement that supports relaxation and helps maintain a sense of balance. Great choice for those looking for a trusted, high-quality option.

Great

No taste, odorless and smooth capsules. The ingredient list is minimal, no unnecessary extras. Light dosage per capsule, with clear label info. Size is easy to take. Bottle has a tamper-proof seal and feels like solid quality.
