Frequently Asked Questions

What is included in the ANTHOSYSTEM pack?

The ANTHOSYSTEM pack contains 4x ANTHOLOADING Drink sachets (for pre-race Days 1–4) + 1x HICARB ANTHO+ Drink sachet (for Day 5 / Race Day).

How does the 5-day protocol work?

Drink 1 ANTHOLOADING sachet each day on Days 1 to 4 before your race. Then consume 1 HICARB ANTHO+ sachet on race morning 1–3 hours before your effort to finish loading and fuel your performance.

Why combine Antholoading with HICARB ANTHO+?

Antholoading saturates muscle tissues with 300mg anthocyanins per day across 4 days without extra caloric bulk. HICARB ANTHO+ completes the loading cycle on race day by providing 300mg anthocyanins alongside 50g of high-density carbohydrates for optimal performance.
