OL Oylmpian Labs Lean & Healthy Greens 8 in 1 Blueberry

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. However, based on the data provided, we cannot assess the effectiveness of the “8 in 1” blend of greens, as specific ingredient amounts and studies for this formula are not available. The data on calcium is well-established, but the overall product’s benefits are unclear without more information.

How it works

Calcium works as a master regulator for your body. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. Think of it as the key building block for your skeletal structure and a critical component for nerve and muscle function.

Safety profile

Data not available for this specific product’s adverse events. However, for the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine calcium levels 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]. The FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not provided [FDA data].

Our recommendation

Our assessment: proceed with caution. Without knowing the exact amounts of each ingredient, we cannot recommend this product for a specific health goal. If you are taking medications for osteoporosis, thyroid conditions, or infections, be aware that calcium can reduce the absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your doctor before starting this supplement.
