What is Epimedium Extract?
Magnesium Gluconate is a highly bioavailable magnesium salt of gluconic acid, widely used in dietary supplements and functional foods due to its excellent absorption and gentle digestive profile. With the CAS number 3632-91-5, molecular formula C12H22MgO14, and molecular weight of 414.6 g/mol, it typically appears as a white crystalline powder that is soluble in water. Our premium-grade material is produced at 99% purity (HPLC) and packaged securely in 25kg fiber drums for bulk supply. Magnesium is essential for energy production and supports the absorption of key minerals like calcium and potassium, making magnesium gluconate a preferred ingredient in nutraceuticals and pharmaceuticals. ProVita Biotech Co., Ltd. is the leading bulk magnesium gluconate powder supplier in China, offering not only raw material supply but also OEM solutions for capsules, tablets, and blends. In addition, we provide other popular magnesium ingredients including Magnesium Acetyl-Taurate Powder, Magnesium Glycinate Powder, and Magnesium Oxide Powder.

Epimedium species
Epimedium, also known as Horny Goat Weed, is a traditional herb with several species commonly used in dietary supplements. Among these, Epimedium brevicornum, Epimedium sagittatum, and Epimedium grandiflorum are the most recognized sources. While all three contain icariin, the concentration and commercial applications vary, making some species more suitable than others for producing standardized extracts such as Icariin 20% powder.
Epimedium brevicornum is widely considered the best source of icariin. This species naturally contains the highest levels of the active flavonoid, making it ideal for standardized extracts ranging from 10% to 60% icariin. Because of its potency and consistent quality, brevicornum is the preferred choice for bulk icariin production in the nutraceutical industry. It is the most reliable species when manufacturers require high-purity extracts for sports nutrition, testosterone support, and male vitality products.
Epimedium sagittatum has a moderate icariin content compared to brevicornum. In traditional Chinese medicine, it has been used to support kidney and liver health, and it is often included in herbal blends for overall wellness. While not the strongest source of icariin, sagittatum offers a broader range of naturally occurring flavonoids, making it useful in formulations where a holistic herbal profile is preferred over high icariin purity.
Epimedium grandiflorum, also known as Japanese Horny Goat Weed, typically contains lower icariin concentrations than brevicornum and sagittatum. It is most common in Japanese and Korean herbal practices, often used in formulas for libido support and bone health. However, it is less popular for large-scale commercial icariin extraction, as its lower potency makes it less efficient for producing high-standardized extracts like Icariin 20% or 40%.
Overall, Epimedium brevicornum stands out as the best species for manufacturing high-quality bulk icariin extract powders, while sagittatum and grandiflorum are more suitable for traditional and regional herbal applications.
Epimedium Extract Specifications
When evaluating Epimedium extract, it is important to distinguish between icariin and icariins. Icariin refers to the single, well-defined flavonoid glycoside that is recognized as the most active compound in Horny Goat Weed. It is typically standardized at levels such as 5%, 10%, 20%, 50%, 90%, or 98% using HPLC testing methods. Icariins, on the other hand, represent a group of related flavonoids found in Epimedium, offering a broader spectrum of compounds. These are usually standardized at 5%, 10%, or 20%. While icariin is often preferred for products focused on potency and clinical consistency, icariins extracts are sometimes chosen for formulas emphasizing a more complete phytochemical profile.
At ProVita Biotech, we offer a wide range of Epimedium extract specifications to meet different market needs. Our icariin extracts are available in purities of 5%, 10%, 20%, 50%, and up to 98%, providing options from cost-effective formulations to premium high-potency extracts. We also supply icariins 5%, 10%, and 20%, as well as total flavonoids standardized to 10%–40%. Popular specifications such as Epimedium extract 20% icariin, icariin 90%, and 98% icariin are widely used in dietary supplements, sports nutrition, and men’s health products.
In terms of appearance, Epimedium extract is typically a brownish-yellow to yellow fine powder with a slightly bitter taste and unique herbal aroma. It is insoluble in water but soluble in methanol and ethanol, which makes it suitable for various extraction and formulation processes.
For quality preservation, the extract should be stored in a cool, dry place away from direct light and high temperatures. Our standard packaging includes 1kg aluminum foil bags and 25kg fiber drums with a double plastic liner inside and a cardboard drum outside. The product has a shelf life of two years under proper storage conditions.
By offering flexible specifications, reliable testing, and stable quality, ProVita Biotech ensures that our Epimedium extract can support diverse applications, from bulk raw ingredient supply to customized OEM formulations.

Epimedium extract, standardized to icariin, is widely used in men’s health supplements to support libido, stamina, and testosterone levels. It is a popular ingredient in capsules, tablets, and herbal blends targeting sexual performance and vitality.
Bone and Joint Health
Rich in flavonoids, Epimedium extract helps promote bone density and anti-osteoporosis activity, making it suitable for nutraceuticals and functional foods that focus on long-term joint and skeletal support.
Sports Nutrition
With natural testosterone-boosting properties, Epimedium extract is included in pre-workout and performance supplements to improve strength, endurance, and recovery, making it a key raw material in sports nutrition formulations.
Epimedium Extract Manufacturing Process
At ProVita Biotech, the production of Epimedium Extract Icariin 20% begins with carefully selected Epimedium sagittatum raw materials. The plant leaves and stems are extracted using 70% ethanol at 80°C for 1.5 hours to ensure maximum recovery of active flavonoids. The extracts are then concentrated under reduced pressure (-0.02~0.06 MPa) until no alcohol remains, followed by cooling, standing, and filtration to obtain a clean extract solution.
The extract undergoes chromatographic separation to isolate and enrich bioactive compounds. From this step, two product streams are developed: one directed toward icariin crystallization and another toward flavonoid-rich powder production. For icariin-rich material, the solution is recycled with ethanol and concentrated to a specific gravity of 1.05–1.10, followed by 95% ethanol hot melt treatment, filtration, crystallization, and drying, yielding Product 1 – Icariin ≥20%. For broader-spectrum extracts, the alcohol solution is concentrated to 1.08–1.10, spray-dried, crushed, sieved, mixed, and packaged to produce Product 2 – Icariin 10%.
The standard output is Epimedium Extract with Icariin 20% (HPLC tested), widely used in dietary supplements for male vitality, bone health, and sports nutrition. Upon request, ProVita Biotech can further refine the purity through advanced crystallization, providing high-purity icariin up to 98% for specialized formulations.
Every batch is tested for assay (HPLC), heavy metals, residual solvents, microbiological safety, and physical properties in compliance with USP, CP, and AOAC methods. The final products are securely packed in 25kg drums with double plastic liners, with a shelf life of three years under proper storage conditions.
With a strict GMP-certified production process, international standards compliance, and third-party quality verification, ProVita Biotech guarantees that its Epimedium Extract meets the highest requirements for nutraceutical and supplement manufacturers worldwide.
