Blue 2 Lake.
A synthetic dye that makes your supplement look blue. That's it. It colours a tablet or coating blue. The dye sits on an insoluble aluminium salt, which lets it tint dry and fatty layers without bleeding. It has no physiological job.

What Blue 2 Lake is, and what it does.
- Does it work
- Purely cosmetic. Zero health value.
- How much to take
- There's no amount to aim for and no figure on record. The maker uses tiny amounts to colour a coating, so it rarely appears with a number on a label.
- Time to feel it
- Its job is finished the moment the tablet is coated, and that job is colour. No time course exists because there is no physiological effect to time.
- The first dose
- Day one is a blue tablet, and that is the point. It isn't an active, so there's no onset to time, and its job is done the moment you see the colour.
- With regular use
- Weeks of use add nothing to the body. What it contributes over time is a product that looks identical from the first tablet in the bottle to the last.
- How well tolerated
- At the small amounts that colour a coating it is well tolerated, and regulators set an acceptable daily intake for it. Ask your doctor if you react to added colours.
- How it feels
- A colour at these amounts has no taste and no sensation. What you notice is how the tablet looks.
- The overlooked benefit
- A lake is the dye anchored onto an insoluble aluminium salt, which is what lets it colour a dry coating or a fatty centre without bleeding the way a water-soluble dye does.
