7 Supplements That Can Cause Acne (2 of 4)

Iodine

The body absolutely needs iodine for normal thyroid function. But to be honest, for most people an iodine supplement is unnecessary since we already get a sufficient amount from iodized salt and seafood. The problem is that when people do feel like they need to take an iodine supplement, they choose kept and other seaweed-based products, which often contain high amounts of iodine. For certain people, excessive iodine can trigger acne breakouts, which appear as inflamed pustules or whiteheads, particularly on the face and chest. If you notice acne developing after you’ve started an iodine regimen, checking the product’s ingredients and dosage may help identify a possible connection.

Whey Protein

Whey protein is the preferred supplement for athletes and those aiming to build muscle, but it can lead to significant issues for individuals prone to acne. Whey is derived from milk, and consuming it can increase levels of insulin and insulin-like growth factor. These hormones may influence oil production and other processes involved in acne development.

As it stands, there is plenty of research linking dairy consumption with acne in some people, and because concentrated whey protein delivers so much dairy in a single serving, it increases the risk of acne. If you’ve added whey protein to your diet and are noticing persistent breakouts, you should probably consider alternative, non-dairy protein sources.
