## WINFORCE O2 MAXX Booster 65 ml – Beetroot

The WINFORCE O2 MAXX Booster is a ready-to-drink **nitrate shot** based on beetroot concentrate for intense endurance efforts. Each 65‑ml ampoule delivers **500 mg nitrate** as well as **2’500 mg L‑Arginine** and **1’000 mg L‑Citrulline**; this corresponds roughly to 700 ml of beetroot juice in concentrated form. As part of the WINFORCE **Signature Line**, the product is developed and manufactured in Switzerland with a focus on efficacy, tolerability and taste. Dietary nitrate from beetroot supports the body’s **nitric oxide** production, which can influence blood flow and oxygen utilization under load; this strategy is among the few evidence-based performance supplements.

- Formula with **L‑Arginine** and **L‑Citrulline** to complement the nitrate pathway
- Store cool and dry; keep out of reach of children

## Technical Details and Functions

The formula combines beetroot concentrate with **L‑Arginine (3.2 %)** and **L‑Citrulline‑Malate (2 %)**; other ingredients include water, sucrose, **citric acid** and **potassium sorbate**. Per ampoule there are **500 mg nitrate** (≈ 8 mmol), placing the booster in the literature‑recommended range of about 5–9 mmol per intake; an effect is typically observed when taken around 2–3 hours before the start of exercise. The shot also provides **132 kcal** and **27 g sugar**, which can serve as quickly available **carbohydrates** before intense sessions; no fat is present. Studies show that nitrate can improve oxygen economy and extend time to fatigue, while effects on time‑trial performance are generally small to moderate and depend heavily on the protocol (acute vs. multi‑day). The oral microbiota plays a key role in the nitrate–nitrite–NO conversion; antibacterial **mouthwashes** can measurably blunt this conversion – therefore try to avoid them around the time of ingestion.

## Applications and Benefits

Ideal for road races, marathon MTB, cyclocross, triathlon segments or hard interval days when you want to specifically support **oxygen transport** and **economy**. The literature indicates benefits for efforts lasting from a few minutes up to around 40 minutes, especially with repeated intake over several days; test the timing in training to determine your individual response. In competition, a timing window of about **2–3 hours** beforehand has proven effective, and many athletes also use a short loading period of **>3 days** to optimize effects. Thanks to **SWISS MADE** and the compact 65‑ml ampoule, the booster fits easily in a jersey and is a convenient pre‑race shot. Individual responses vary, so test in training; the recommended daily dose of one ampoule should not be exceeded.

## Usage and Tolerability

Shake well before use and drink one ampoule neat; chilled the taste is particularly pleasant, and the ampoule is also **pasteurized**. Store the shot **cool and dry** and keep it out of reach of children; the recommended daily intake of one serving is the upper limit. As with all **supplements**, consult a professional if you have existing medical conditions or take medication; the general principle is a food‑first approach. Note for your **carbohydrate strategy** that one ampoule provides **27 g sugar** and should be counted into the total intake before or during the session. In practice, it is advisable to avoid strong **mouthwashes** in the period of about 2–4 hours after ingestion so that the bacterial nitrate reduction in the mouth can proceed optimally.
