REIN focuses on simplicity, transparency, and scientific integrity. Every product contains only essential ingredients, nothing added without purpose. We test all raw materials using FTIR to confirm identity, and all finished products for purity and safety.
We believe in giving you full control over your nutrition. By keeping our products unflavoured and free from unnecessary additives, you can mix them into shakes, smoothies, or meals your way. Purity also means fewer ingredients and less chance of unwanted reactions or intolerance.
Yes. REIN products are designed for general use by adults seeking simple, clean nutritional support. They can complement an active lifestyle or everyday nutrition plan. Always consult a healthcare professional if you have specific medical or dietary conditions.
FTIR (Fourier Transform Infrared Spectroscopy) testing verifies that every raw material is what it is supposed to be according to our label. For example, if it is supposed to be Creatine, it must closely match a 100% Creatine reference spectrum before we use it in production.
All REIN products undergo independent laboratory testing for heavy metals, including lead, cadmium, mercury, and arsenic, as required under South African food regulations. Whey Protein is additionally tested for true protein content to ensure label accuracy. We only release products that meet our internal REIN standards for purity and quality.
Each product comes with its own usage suggestion on the label and product page. Because our products are unflavoured and versatile, you can mix them with water, juice, smoothies, or other foods according to your preference.
Yes. REIN products are single-ingredient and unflavoured, allowing you to create your own combinations or stacks. For example, you can mix Collagen with Whey Protein or L-Glutamine for additional nutritional support.
All REIN products are manufactured in South Africa in a FSSC 22000 certified facility, following strict quality and food safety standards. Each batch is independently tested by REIN before being released to ensure it meets our standards of purity and consistency.
Suitability varies between products. Some REIN products are suitable for vegetarians or vegans, while others, such as Whey Protein and Collagen Peptides, are not. Each product page clearly specifies whether it is suitable for vegetarians or vegans.
Keep all powders tightly sealed in a cool, dry place away from moisture and direct sunlight. Avoid refrigeration or freezing.
Yes. As we grow, REIN will introduce lightly flavoured or functional products, but always with purpose. Any added ingredient will serve a clear function and be fully disclosed. Our commitment to purity and transparency will never change.
