Asu Concentrate Blend
Also known as: Piascledine, Avocado-soybean unsaponifiables, Avocado-soybean unsaponifiables (ASU)
Overview
Avocado-soybean unsaponifiables (ASU) is a dietary supplement derived from unsaponifiable fractions of avocado and soybean oils. It primarily contains phytosterols such as β-sitosterol, campesterol, and stigmasterol. ASU is primarily used for managing symptoms associated with osteoarthritis, particularly in the knee, by potentially reducing pain and improving joint function. The body of research surrounding ASU includes several randomized controlled trials (RCTs) and meta-analyses that support its efficacy, although the evidence quality varies. Notably, ASU is thought to have anti-inflammatory properties that can affect joint health positively. ASU is generally safe for most populations but should be used with caution in individuals with known allergies to soy or avocados.
Benefits
ASU has been shown to significantly reduce pain in patients suffering from knee osteoarthritis, as evidenced by a meta-analysis that demonstrated a weighted mean difference of -17.36 mm on the visual analog scale (VAS) (95% CI: -25.91, -8.82; P < .0001). Additionally, it may improve joint function, particularly noted in reductions in the Lequesne index among knee OA patients. The benefits are particularly pronounced in symptomatic knee OA populations, with a clinical significance reflected in a moderate to large effect size. Although results vary, the onset of benefits generally becomes noticeable within several months of continued use.
How it works
ASU is believed to function by modulating inflammatory pathways, inhibiting matrix metalloproteinases (MMPs) that degrade cartilage, and enhancing the synthesis of collagen, vital for joint structure and function. It interacts with the musculoskeletal system, targeting pathways involved in joint repair, such as transforming growth factor-beta (TGF-β), promoting a healthier inflammatory response and maintaining cartilage integrity. This mechanistic action supports its efficacy in reducing symptoms of osteoarthritis.
Side effects
ASU is generally considered safe, with adverse events reported at rates similar to placebo. Common side effects occurring in over 5% of users include gastrointestinal symptoms such as nausea and dyspepsia. Uncommon side effects reported (1-5%) are skin reactions and liver enzyme elevations. Serious adverse effects are rare (<1%) and poorly documented. As with any supplement, caution is urged for individuals with soy or avocado allergies. Pregnant or breastfeeding women should consult healthcare professionals prior to use. Though evidence of significant drug interactions is limited, patients taking medications affecting liver function should evaluate possible interactions with ASU.
Dosage
The typical dosage of ASU ranges between 300 mg to 600 mg per day, with a minimum effective dose reported at approximately 300 mg based on clinical studies. ASU is usually taken with meals to mitigate gastrointestinal side effects. Higher doses have not been thoroughly researched, and there isn't a formally established maximum safe dose. It is recommended to take ASU in the form of capsules or tablets, and absorption may be influenced by concurrent dietary fat intake.
