Life Extension Gummy Science Youthful Collagen Cherry

Our assessment

The evidence shows that this product provides 500 mg of calcium per serving, a mineral essential for bone health and muscle function [NIH ODS]. For most adults, this is a meaningful contribution toward the 1,000 to 1,200 mg daily target, but it should not replace a balanced diet or other calcium sources. You should consider your total daily intake from all foods and supplements to avoid exceeding safe levels [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves and muscles. It supports bone mineralization by depositing into your bone matrix, and it helps your muscles relax and your nerves transmit signals properly [NIH ODS]. Without enough calcium, your body will leach it from your bones, which can weaken them over time [NIH ODS].

Safety profile

FDA has received a total of 592,059 adverse event reports across all products in their system [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer, and very high blood levels can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a higher risk of death from heart disease [NIH ODS]. Be aware that calcium supplements can reduce the absorption of certain medications, including bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on side effects specific to this gummy product.

Our recommendation

Start by assessing your total daily calcium intake from food and other supplements. If you use this product, take it with food for better absorption, and separate it from any thyroid or antibiotic medications by at least two hours [NIH ODS]. Do not exceed 2,000 mg of total calcium per day from all sources unless directed by your doctor [NIH ODS]. Choose this gummy only if you prefer a chewable format and can account for the added sugars.
