FAQs
What is Liposomal Delivery?
Liposomal delivery is a technique used to help support the absorption and bioavailability of certain nutrients. It involves encapsulating the active ingredient within tiny lipid-based bubbles called liposomes. These liposomes act as protective carriers, helping the nutrient pass through the digestive system and supporting its absorption into the body.
Why do our products contain Sunflower Lecithin?
Sunflower lecithin is often confused with sunflower oil, but the two are very different. While sunflower oil is simply the pressed oil from sunflower seeds, sunflower lecithin is a special substance extracted from these seeds that contains important nutrients called phospholipids. One key phospholipid it provides is phosphatidylcholine, which is essential for building true liposomes—tiny, protective “bubbles” that can carry nutrients into your cells more effectively. In other words, sunflower lecithin is not the same as the sunflower oil you’d use in cooking. Instead, it’s a natural, safe ingredient that helps create stable, high-quality liposome supplements to improve the delivery and absorption of vitamins and other nutrients.
What are the "Natural Flavors" used?
Although the term "Natural Flavors" is often used ambiguously or even misleadingly by other brands to hide nasty ingredients, rest assured that our natural flavors are nothing but highly purified plants, herbs, and citrus extracts. They're formulated by our expert flavorists exclusively to enhance taste, without any of the concerning additives you might find elsewhere.
Do you test your products and check for contaminants?
Yes, at Rho Nutrition every single product undergoes a rigorous quality control process ensuring we are setting the industry standard for quality and safety. Every step of the manufacturing process is carefully documented, tested and done in a cGMP, FDA registered and allergen free facility. Every product undergoes third party testing for purity, safety, and potency.
