Overview
Lemon Bottle at a glance
The three ingredients are very different kinds of material. Riboflavin (vitamin B2) is a single small molecule with a defined formula. Bromelain is a mixture of cysteine proteases extracted from pineapple, so it is quantified by enzyme activity rather than by molecular weight. Lecithin is a mixture of phospholipids in which phosphatidylcholine usually predominates.
Two of the three ingredients are therefore mixtures with natural variation between lots. Two different batches can be correctly labelled and still differ in enzyme activity or in the fatty-acid composition of the phospholipids, which is why the batch documents should state the grade and the assay method for each.
Vesta lists the product as a kit of 10 vials at 10 mL per vial. The physical form of the vial and the concentration of each ingredient are not given in the listing.

Expected ions by component
Use these values to look for each component in an LC-MS run of the blend. Ions are calculated from the monoisotopic masses above. See the guide to average and monoisotopic mass.

Analytical notes for batch documents
- Riboflavin is yellow-green, fluorescent and sensitive to light. It absorbs near 267, 373 and 445 nm, so its presence and amount can be checked by UV-visible spectroscopy or fluorescence.
- Bromelain is measured in activity units (for example gelatin-digesting units) rather than milligrams of protein. Ask for the activity per millilitre and the assay used.
- Lecithin is usually specified by its phosphatidylcholine content, measured by HPLC with a light-scattering detector or by 31P NMR. A UV chromatogram at 220 nm is not a suitable test.
- Bromelain is a protease. It digests peptides and proteins, so keep it separate from peptide stock solutions when planning in vitro experiments.
- Ask for the formulation sheet with the concentration of each ingredient and for the physical form, appearance and pH of the vial.

Questions
Frequently asked questions
What is Lemon Bottle?
Lemon Bottle is described by the manufacturer as a three-component research formulation of riboflavin, bromelain and lecithin, listed at 10 mL per vial.
What is the molecular weight of Lemon Bottle?
Lemon Bottle is a mixture, so it has no single molecular weight. Its defined components have the following average molecular weights: Riboflavin (vitamin B2) 376.36 g/mol.
How can I check the identity of a batch of Lemon Bottle?
Check each defined component separately: find its expected ions in the LC-MS data and confirm that its own chromatographic peak carries them. Ask for the formulation sheet, the declared amount of every ingredient and the assay used for each, and confirm that the batch code on the report matches the vial.
Which Lemon Bottle products does Vesta list?
Vesta lists 1 product for Lemon Bottle: 10 mL per vial in kits of 10 vials. Prices are shown per kit in US dollars, and shipping is paid by the customer.
What does Lemon Bottle contain?
The manufacturer describes it as a combination of riboflavin, bromelain and lecithin. Amounts per vial are not published, so request the batch formulation sheet.
Can bromelain be mixed with peptide research materials?
It should not be added to a peptide solution, because bromelain is a protease and cleaves peptides. Keep the two separate in in vitro experiments unless digestion is the purpose.
