Alani Nu Collagen + Hyaluronic Acid Unflavored

Our assessment

The evidence shows that a collagen and hyaluronic acid supplement like Alani Nu Collagen + Hyaluronic Acid Unflavored may support skin hydration and joint comfort, but the specific data provided is limited. Data not available for the exact formulation or its specific outcomes for collagen or hyaluronic acid. However, the product contains calcium, and our assessment focuses on that ingredient’s role based on available data [NIH ODS].

How it works

Think of calcium as a structural builder for your bones and a signal regulator for your nerves. It supports bone mineralization and density, and helps your muscles relax and nerves signal properly [NIH ODS]. For a product like this, the calcium may contribute to bone health, though it is not the primary ingredient for skin or joint support.

Safety profile

FDA received 592059 total adverse event reports across all dietary supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels in blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation is to check the label for the exact calcium dose per serving. If you are taking medications that interact with calcium, or have a history of kidney stones or heart conditions, consult your doctor before using this product. For skin and joint support, you may consider other supplements with more direct data, but this product is generally safe when used as directed if you are not at risk for calcium overload [NIH ODS].
