Some Solgar supplements contain magnesium stearate—how safe is it?

Magnesium stearate is an excipient used in nearly all tablet-form vitamins (not just in Solgar). It serves as:

A lubricating agent, preventing tablets from sticking to manufacturing equipment

A tablet shape stabilizer

Safety:

Considered safe in small doses (and in supplements, it’s present in microgram amounts)

Does not accumulate in the body

Does not affect vitamin absorption (contrary to myths)

Approved by the FDA, EFSA, and other regulators as food additive E470b

📌 Concerns arise only with excessive doses or industrial-scale stearate in large volumes, but in Solgar, everything is within safe limits.

❗ If you prefer to avoid any additives, choose Solgar in capsule or liquid form, where magnesium stearate may be absent.

And if you suspect you’ve been sold a counterfeit product with excessive additives — 👉report it on Xolvie👈 to help prevent the spread of low-quality products.
