Three things in your category worth acting on this month.

A competitor ran a promotion it could not fulfil.

Every product in the Key Nutrients electrolyte line reads sold out, and it read the same on both 22 and 23 September. That covers the 10- and 20-count variety packs, every flavour and size of Electrolyte Recovery Plus, the hydration capsules, and the gut-health SKU. Meanwhile the storefront is still running "Buy any 3 products, 20% off 20-count packs", ending 29 September, along with a standing subscriber offer of 30% off the first order and 20% thereafter.

They were spending to create demand in a category with near-zero switching cost, and sending it to an empty shelf.

Update, 24 September: the line was back in stock when checked on the morning of the 24th. The empty-shelf window lasted at least two days, and it was open while their promotion was still running.

What it means

This was a supply failure, not a pricing move. While it lasted, their subscribers were the most portable customers in the category, and their paid traffic was worth more to anyone with stock than it was to them.

Do this

Windows like this close in days, which is too fast to plan for from scratch. Have a conquest campaign on your nearest competitors' brand terms built and paused, so it can go live the morning their stock goes out.

The category leader opened Q4 gifting in September.

Liquid I.V.'s storefront has carried "20% off gift boxes with code HOLIDAY20" since at least 22 September, and it was still live on the 23rd. They are also promoting a new Mango Passion Fruit Hydration Multiplier with immune support, and free shipping above $40.

Gifting is how this category reaches households that would never buy it for themselves. The largest brand in the category has just set the discount anchor for that occasion, roughly ten weeks before anyone expected it.

What it means

Twenty percent is now the reference price for a hydration gift box this season. A gifting SKU launched in November enters a market where the anchor is already set and the inbox space already bought.

Do this

Make the gifting call in the next two weeks. If you are going, the bundle needs to exist by mid-October. If you are not, decide that deliberately and move the budget to retention, rather than discovering the decision by default in week 46.

A serving is not a unit, and the category's price list flips when you notice.

Every brand prices by the serving, and every comparison a buyer, a retailer or an AI assistant makes starts from that number. But a serving here carries anything from 50mg of sodium to 1,000mg. Across the products reviewed, price per serving spans 5×. Price per 100mg of sodium spans 24×, and the two rankings nearly invert.

LMNT is the second most expensive product here per serving, at $1.50, and the third cheapest per unit of sodium. Buoy is the cheapest per serving, at $0.33, and tenth of twelve per unit of sodium; it also recommends four to seven servings a day, and at five that comes to $1.63 daily, more than one LMNT stick. Ultima sits mid-table per serving and last per unit of sodium, by a wide margin. The exception that proves the rule is Hi-Lyte's liquid concentrate: second-cheapest on both measures, and delivering LMNT's 1,000mg for $0.92 against LMNT's $1.50.

What it means

Pricing by the serving structurally flatters low-dose products and punishes high-dose ones, and nobody chose that; it is simply the number printed on the pack. Three of the brands reviewed (Buoy, Cure and Key Nutrients) do not state milligram values on their product pages at all. When you do not publish the number, someone else's number gets used.

Do this

If you are high-dose, publish your cost per gram of electrolytes, because the arithmetic is in your favour and nobody is doing it for you. If you are low-dose, say plainly what the product is for (a daily mineral top-up, not sweat replacement) before a comparison article runs these numbers and presents you as the most expensive electrolyte on the market.
