## Description

Digestive Support Immune Support

Review: Excellent - Excellent
Review: Outrageously overpriced - Good product, but the price has shot up from £40 last month to £80 this month. That's just shameful profiteering. Less than half that price elsewhere, so don't fall for it - check out BigVits and Dolphin.

## Features

- One of L-arginine’s unique functions is that it is necessary for the production of nitric oxide. Nitric oxide is essential to the regulation of blood flow in the body. By supporting nitic oxide levels, L-arginine can support cardiovascular health, benefit healthy blood pressure, and optimize blood flow to the extremities
- Sustained Release: Provided in a sustained-release formula to maintain optimal levels of L-arginine over 24 hours with suggested twice-daily use
- How to Use: Take 2 capsules two times daily or as recommended by your health-care practitioner
- Free From: Every Thorne product is made with the purest possible ingredients. This product contains no gluten, soy, dairy, shellfish, or fish
- Our Mission: We believe personalised, scientific wellness can extend the duration of one's health span, create happier and healthier lives, and feel one’s best at every age and life stage
