Description
Doctor’s Best L-Arginine 1000mg – Sustained + Immediate Release
Doctor’s Best L-Arginine 1000mg is a dual-release L-arginine supplement in a tub of 120 tablets. Each tablet is designed with an immediate-release portion and a sustained-release portion, so arginine is made available both quickly and over a longer period. L-arginine is a conditionally essential amino acid found in meat, fish, nuts and seeds, and the body uses it to produce nitric oxide.
Key Benefits
- 1000mg per tablet – a substantial dose of L-arginine in each tablet.
- Dual-release design – immediate plus sustained release in one tablet.
- Nitric oxide precursor – arginine is the amino acid the body converts into nitric oxide.
- Fewer daily top-ups – the sustained-release layer suits people who prefer steady intake.
- 120 tablets – a generous supply for daily use.
Who Is It For?
Suitable for active adults, gym-goers and endurance athletes who want an easy, steady form of arginine. It also suits those who dislike the taste of arginine powder and would rather take a single tablet.
Why Choose Doctor’s Best?
Doctor’s Best is a California-based supplement brand known for science-based formulations and for using researched, branded ingredients across its range.
FAQs
What does sustained release mean?
Part of the tablet dissolves gradually, releasing arginine over a longer period rather than all at once. The immediate-release layer is available straight away.
Can I split or crush the tablet?
No – splitting or crushing can affect the sustained-release design. Swallow tablets whole as directed on the label.
