Why Doctors Do Not Recommend Drinking Collagen Peptides

Generally speaking, there is no such statement as "doctors do not recommend drinking collagen peptide." Due to individual differences in physical conditions, doctors may consider the following factors for specific populations or situations, such as unclear effectiveness, potential allergic reactions, inconsistent product quality, possible interference with the absorption of other nutrients, and potential psychological dependence. If you have any concerns, it is recommended to consult a doctor in advance. Detailed analysis is as follows:

1. Unclear effectiveness

Currently, there is insufficient clinical evidence regarding the efficacy of collagen peptides on skin and joints. Some studies indicate possible benefits, but results are inconsistent, so the exact effectiveness remains uncertain.

2. Potential allergic reactions

Some individuals may be allergic to components in collagen peptides, especially those with allergic constitutions. Allergic reactions may manifest as skin itching, swelling, difficulty breathing, and severe reactions could be life-threatening.

3. Inconsistent product quality

The quality of collagen peptides products on the market varies greatly. Some products may have issues such as low purity, presence of impurities, or unnecessary additives. Consumers may find it difficult to assess product quality and safety, and using low-quality products may cause adverse effects on health.

4. Possible interference with absorption of other nutrients

The metabolism of collagen peptides in the body may interfere with the absorption of other essential nutrients, such as calcium, iron, and zinc. Long-term excessive intake of collagen peptides may lead to deficiencies in these nutrients, affecting overall health.

5. Potential psychological dependence

Some individuals may perceive beneficial effects after taking collagen peptides due to psychological factors, leading to psychological dependence. This dependence may result in excessive use of the product, increasing unnecessary financial burden and health risks.

Therefore, collagen peptides are not suitable for individuals with metabolic disorders, excessive protein levels in the body, underage females, and those with weak gastrointestinal tolerance. Taking collagen peptides may worsen existing conditions or trigger new health problems in these populations.
