Flavour

One Stop Xtreme is an all-in-one nutritional powder combining protein, carbohydrates, amino acids, creatine, vitamins, and minerals in a single formula. It is designed to help support daily nutrient intake as part of a balanced diet and active lifestyle.

Each serving provides a blend of high-quality protein sources alongside carbohydrates and additional ingredients commonly used in sports nutrition products. Protein contributes to the growth and maintenance of muscle mass, while carbohydrates contribute to the recovery of normal muscle function after highly intensive or long-lasting physical exercise.

The formula includes creatine monohydrate (Creapure®), which increases physical performance in successive bursts of short-term, high-intensity exercise when consumed daily at 3g. A range of amino acids, vitamins, minerals, digestive enzymes, and probiotic cultures are included to complement overall nutrient intake.

One Stop Xtreme is supplied as a powdered shake that mixes easily with water and is suitable for use between meals or after training as part of a structured nutrition routine.

FAQS

How should I take this supplement?

Always follow the dosage instructions on the label. Most supplements are best taken with food and water, unless otherwise stated. Do not exceed the recommended daily intake. If you're pregnant, breastfeeding, or taking medication, speak to a healthcare professional before use.

How long before I start seeing the benefits of taking vitamins?

Most people begin to notice subtle improvements within a few weeks, but the full benefits of daily vitamin and supplement use typically build over time. We recommend taking your supplement consistently for at least 12 weeks (3 months) to see meaningful results.

This gives your body time to restore nutrient levels, especially if you're addressing a deficiency or supporting areas like energy, immunity or skin health.

How quickly you see results can depend on the type of supplement and your individual lifestyle. For example:

  • Vitamin B12, Iron and Vitamin D3 may support energy, focus or mood within a few weeks.
  • Multivitamins and skin-related nutrients often take longer as levels build gradually.
  • Consistency is key regular daily use will give you the best chance of seeing results.


To support the process, we also recommend a balanced diet, plenty of water, and a healthy routine alongside your supplement.

Can I take this alongside other vitamins or supplements?

In many cases, yes, but it depends on your overall intake and the specific nutrients involved. To avoid exceeding safe levels of vitamins or minerals, especially fat-soluble ones like Vitamin A, D, E, and K, we recommend checking with a doctor or pharmacist if you're using multiple supplements at once.

Are your supplements suitable for vegetarians or vegans?

We offer a wide range of products, many of which are suitable for vegetarians and vegans. Please check the product label or description for specific dietary suitability, including allergen information, gelatin content, and any added ingredients.

How do I store my vitamins and how long do they last?

Store supplements in a cool, dry place away from direct sunlight, heat, or moisture. Always keep them out of reach of young children. Check the expiry date on the label — most supplements remain effective until that date if stored correctly and sealed after each use.
