LifeTIME Liquid Collagen with Co-Q10 and Resveratrol Natural Orange/Vanilla Flavor 2,000 mg

Our assessment

The evidence shows that this combination product contains calcium, a mineral with well-documented benefits for bone health, but the available data does not provide specific dosage information for the collagen, Co-Q10, or resveratrol in this formulation. For calcium specifically, the primary role is supporting bone density and neuromuscular relaxation [NIH ODS]. However, we must be transparent: without exact amounts of each ingredient from the label, we cannot fully assess the effectiveness of this specific product for you.

How it works

Calcium acts as a master regulator for your bones and muscles. It supports bone mineralization, helping to deposit minerals into your skeleton for strength, and it aids neuromuscular relaxation, which is essential for proper muscle and nerve signaling [NIH ODS]. Think of it as the structural foundation your body relies on daily.

Safety profile

Data not available for this specific product's side effects. However, the FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high levels of calcium in the blood 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]. Additionally, calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you review the product label to confirm the exact amounts of collagen, Co-Q10, and resveratrol. For calcium, keep your total daily intake from all sources (food and supplements) within the established safe limits. If you take any medications, especially those listed in the safety profile, take this supplement at a different time of day to avoid absorption issues [NIH ODS]. Always consult your healthcare provider before starting any new supplement regimen.

• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
