Riavita's Stemax is a formula with more than twenty substances: AFA blue-green algae, brown seaweed with fucoidan, sea buckthorn, reishi, grape seed, Q10, L-carnitine, saffron, various flavonoids, and vitamin B6 and biotin. You take four to six capsules per day, after meals.

From lake and sea

Aphanizomenon flos-aquae, AFA for short, is a blue-green alga harvested mainly from Upper Klamath Lake in Oregon, a lake at an altitude of more than 1200 metres. Fucoidan is a polysaccharide from brown seaweeds such as kelp and wakame, which have been eaten in Japanese and Korean cuisine for centuries. The extract in Stemax contains 85% fucoidan.

Sea buckthorn, reishi and saffron

Sea buckthorn also grows along the Dutch coast; its orange berries are rich in carotenoids and fatty acids. Reishi (Ganoderma lucidum) is known in Chinese tradition as the mushroom of immortality. Saffron, from the stigmas of the crocus, is the most expensive spice in the world per gram.

Careful with many active substances

Stemax combines more than twenty active substances, including Malabar tamarind (Garcinia cambogia), black cumin and a range of flavonoids. Not during pregnancy or breastfeeding and not for children. If you take medication or have a liver condition, consult your doctor first.

Stemax, advanced plant-based formula

Riavita Stemax is a carefully formulated blend of high-quality herbal and fruit extracts, designed to provide the body with a wide variety of natural bioactive compounds. The formula combines AFA blue-green algae, brown seaweeds (fucoidan), sea buckthorn, Ganoderma lucidum, grape seed extract and coenzyme Q10. These ingredients were chosen for their unique properties and their ability to complement each other in composition.

Rich in natural nutrients

Stemax provides a diverse spectrum of nutrients, including essential amino acids, minerals, polyphenols and carotenoids. The AFA algae contributes plant protein, while fucoidan from brown seaweeds contains a complex polysaccharide structure. Sea buckthorn provides a naturally rich blend of antioxidants, and grape seed extract is a concentrated source of polyphenols.

Synergistic components

AFA blue-green algae, a microalga rich in proteins, vitamins and minerals. Fucoidan from brown seaweeds, with unique polysaccharides and natural fibres. Sea buckthorn extract, rich in antioxidants and natural fatty acids. Ganoderma lucidum, or reishi, with a unique complex composition. Grape seed extract, a concentrated source of polyphenols. Coenzyme Q10, an endogenous substance involved in energy processes.

Benefits of the formula

The carefully selected ingredients in Stemax are complementary in composition. The combination of algae, mushrooms, fruit and plant extracts provides a diverse supply of bioactive substances, with attention to purity and consistency. The plant-based capsules are suitable for vegetarians and contain no unnecessary additives.
