Frequently Asked Questions (FAQ)

Why include potassium and magnesium if sodium is the main electrolyte needed?

Sodium is lost in the highest amounts in sweat, but potassium and magnesium play critical roles in muscle function and nerve signaling. Sweat contains less potassium and magnesium than sodium, so lower amounts are sufficient to maintain balance without causing gastrointestinal discomfort.

• Potassium supports muscle contractions and nerve signaling and is lost at about 100-200 mg/L in sweat (Baker et al., 2016).

• Magnesium aids muscle relaxation and energy production, but losses are lower, around 10-40 mg/L (Volpe, 2013, Nutrition Reviews). Replenishing it in small amounts helps prevent muscle cramps and fatigue.

Why not include calcium, zinc, or vitamin D?

These nutrients are important for overall health but aren’t directly involved in hydration and endurance performance. Calcium losses through sweat are minimal, and zinc is primarily needed for immune function, not hydration. Vitamin D, being fat-soluble, is best obtained through food or sunlight rather than an electrolyte mix.

Why do some competitors include extra vitamins and minerals?

Many brands add extra micronutrients as a marketing strategy, but they don’t necessarily improve endurance performance. Our formula focuses on replenishing only what is truly needed based on physiological demands.

Why not just drink homemade salty lime juice instead of paying for BS+T Electrolyte?

While salty lime juice can provide some hydration benefits, BS+T offers accurate dosing, convenience, and better control over electrolyte intake. With BS+T, you can:

• Precisely measure your sodium, potassium, and magnesium intake rather than relying on estimates.

• Lime juice with added salt lacks potassium and magnesium, both of which play a crucial role in hydration, muscle function, and preventing cramps.

• Easily carry and mix the sachets anywhere without the need for fresh ingredients.

• Tailor your consumption based on personal factors like body weight, sport, intensity, and weather conditions.

• Enhance hydration with a balanced blend of citric acid, malic acid, and stevia for improved taste and palatability.

Why we don’t add caffeine to BS+T electrolytes?

Caffeine is a stimulant. BS+T is a hydration and electrolyte product.

Our goal is to help you rehydrate, replenish essential salts, and recover — without interfering with your body’s natural balance. Caffeine, while useful for alertness or performance in short bursts, can actually:

• Act as a mild diuretic, potentially increasing urine output and countering hydration goals.

• Interfere with sleep and recovery, especially if taken later in the day.

• Mask fatigue, which might delay rest or cause overexertion.

For people who want caffeine, it’s easy to add a separate source — coffee, tea, caffeine tablets — with full control over timing and dosage.

But if you just want clean, effective hydration at any time of day — especially during endurance activity, illness, or daily life — BS+T keeps it simple and stimulant-free.
