Who is each format for?

Shoppers who specifically want glass

An imported glass bottle may suit a desk lunch, gift or collection when the container matters as much as the drink. MCR Snack Distro lists a 250ml Red Bull example; check whether glass is allowed at your lunch venue before ordering.

Shoppers tracking caffeine

Pack size matters if lunch is one of several sources of caffeine in your day. Red Bull UK states 80mg in a 250ml Original can; Monster Energy UK states 160mg in a 500ml Original Green or Absolutely Zero can.

Shoppers comparing sugar formulations

Compare the exact variant rather than judging by its bottle or can. Monster Energy UK lists 0g sugar for its 500ml Absolutely Zero can, while Sainsbury’s lists 0.1g sugars per 100ml for Lucozade Zero Pink Lemonade in a plastic bottle.

What matters when choosing?

Decide whether glass is essential for your lunch setting, then compare the exact drink’s full-pack caffeine, sugars and serving size.

Priority What to check Your needs
Caffeine Read the amount in the whole can or bottle, not just per 100ml. Red Bull UK lists 80mg per 250ml Original can; Monster Energy UK lists 160mg per 500ml Original Green or Absolutely Zero can. I want to know how much caffeine one complete drink adds to what I have already had from coffee, tea or other sources.
Sugars Compare the same measure and the exact variant. Red Bull UK lists 27g sugars per 250ml Original can; Monster Energy UK lists 55g per 500ml Original Green can and 0g per 500ml Absolutely Zero can. A zero-sugar formulation might suit what I am looking for, but I will check its caffeine separately.
Container Confirm the material on the listing. MCR Snack Distro identifies its imported 250ml Red Bull bottle as glass; Sainsbury’s identifies the Lucozade Energy Original 380ml bottle as plastic. Check whether glass is permitted at your lunch venue. Is glass presentation important to me, or would a can or plastic bottle work for this lunch?
Pack quantity Distinguish the drink you will carry from the quantity you are buying. The Joybuy options below include 24 Red Bull cans, 12 Monster cans or eight Lucozade bottles per pack. One drink fits in my lunch bag, but I also need to decide whether a multipack suits how often I will use it.

Mistakes to avoid

  • Assuming “bottle” means glass

    Sainsbury’s identifies the Lucozade Energy Original 380ml bottle as plastic, whereas MCR Snack Distro identifies its imported Red Bull bottle as glass. The word “bottle” alone does not settle the material.

    If glass is essential, check the packaging description for the exact product before ordering.

  • Assuming zero sugar means less caffeine

    Monster Energy UK lists 160mg caffeine per 500ml can for both Absolutely Zero and Original Green, although their stated sugar amounts differ.

    Choose a sugar formulation on its own terms, and compare caffeine per complete can separately.

  • Judging the drink by its glass packaging

    MCR Snack Distro lists 80mg caffeine and 28g sugars in its imported 250ml Red Bull glass bottle. Those are retailer-supplied figures for that bottle, not figures for every glass-bottle drink.

    Read the caffeine and nutrition information for the exact bottle rather than using its container as a guide to its contents.

  • Confusing a planned age restriction with a current retailer policy

    The Department of Health and Social Care announced a proposed England sales ban for under-16s covering drinks with more than 150mg caffeine per litre, intended for April 2027 subject to Parliamentary approval. Separately, Sainsbury’s states that it already restricts sales of high-caffeine energy drinks to under-16s.

    For an under-16 purchase, check the current rules in the relevant UK nation and the retailer’s age-verification policy.

Brand and product-line references

Packaging and nutrition figures vary by product and variant; a brand name alone does not identify the container or full-serving amounts.

Red Bull

Red Bull UK describes its Original drink in a 250ml can. MCR Snack Distro separately lists an imported 250ml glass-bottle product.

  • Red Bull UK states 80mg caffeine and 27g sugars per 250ml Original can.
  • The specialist retailer lists 28g sugars per imported 250ml glass bottle; do not substitute the can’s nutrition figures for the bottle’s.

Monster Energy

Monster Energy UK provides full-can figures for its 500ml Original Green and Absolutely Zero variants.

  • The manufacturer lists 55g sugar for Original Green and 0g for Absolutely Zero per 500ml can.
  • Both cited variants list 160mg caffeine per 500ml can, so their different sugar figures do not indicate different caffeine amounts.

Lucozade Energy

The Lucozade products listed by Sainsbury’s include plastic-bottle options rather than the glass format at issue here.

  • Sainsbury’s lists 17.1g sugars per 380ml bottle of Lucozade Energy Original and 0.1g sugars per 100ml for Lucozade Zero Pink Lemonade.
  • These figures describe different products and serving measures; check the exact bottle when comparing them.

Relentless

Relentless Energy UK directs shoppers to retailers including Morrisons, One Stop, Sainsbury’s, Tesco and Co-op.

  • Its retailer list gives shoppers places to check for the exact drink and pack they want.
  • Compare caffeine, sugars and container material on the specific product label before treating it as an alternative to a glass bottle.

Joybuy options for lunch on the go

These are can and plastic-bottle options for shoppers considering a different format from glass. Each listing is a multipack, so check both the individual drink size and the quantity in the pack.

Red Bull Sugarfree Energy Drink 250ml, 24 cans

Red Bull Sugarfree Energy Drink 250ml, 24 cans

A 250ml can is an alternative when you want a smaller individual drink rather than a glass bottle. This listing is for 24 cans; check the Sugarfree pack label for its caffeine and nutrition figures rather than using figures for Red Bull Original.

Monster Energy Green Zero Sugar, 12 cans

Monster Energy Green Zero Sugar, 12 cans

For a larger can instead of glass, Joybuy identifies this pack as 12 cans of 500ml each. Check the caffeine amount on this exact Green Zero Sugar variant before comparing a whole can with a smaller serving.

Lucozade Energy Original, eight 380ml bottles

Lucozade Energy Original, 8 × 380ml

This eight-bottle pack offers an individual bottle rather than a can, but Sainsbury’s identifies the matching Lucozade Energy Original 380ml bottle as plastic, not glass, and lists 17.1g sugars per bottle. Check the label for caffeine per bottle if you are comparing complete servings.

Frequently asked questions

Is a glass-bottle energy drink practical for lunch on the go?

It can be if you specifically want the glass presentation and your lunch venue permits it. MCR Snack Distro lists an imported 250ml Red Bull glass bottle; check the container material and the rules where you plan to carry or drink it before buying.

How do I compare caffeine in 250ml and 500ml cans?

Compare caffeine in the whole can and include other sources consumed that day. Red Bull UK states 80mg per 250ml Original can, while Monster Energy UK states 160mg per 500ml Original Green or Absolutely Zero can. The European Food Safety Authority’s caffeine assessment considers intake from all dietary sources, not energy drinks alone.

What caffeine information matters during pregnancy?

The NHS advises no more than 200mg of caffeine a day during pregnancy and includes energy drinks among caffeine sources. Check the amount in the complete drink alongside caffeine from other food and drinks; seek advice from your maternity team about individual circumstances.

Can an under-16 buy a high-caffeine energy drink in England?

Check the current rule and the retailer’s policy rather than assuming a proposed ban is already in force. In July 2026, the Department of Health and Social Care announced an intended England ban from April 2027 on sales to under-16s of drinks containing more than 150mg caffeine per litre, subject to Parliamentary approval. Separately, Sainsbury’s states that it does not sell high-caffeine energy drinks to under-16s and applies age verification to products marked as not recommended for children.
