Can I take Magnesium Glycinate 350mg with other supplements or medications?

  • Magnesium Glycinate is an excellent foundation of daily wellness, but ask your healthcare provider if it could interact with other supplements and/or medications.

Customers Also Ask

What makes Solaray Magnesium Glycinate stand out as an excellent choice?

Solaray’s magnesium glycinate supplement is formulated with magnesium bisglycinate, which is believed to offer increased availability of magnesium to the body.* This high-absorption formula was voted Best Single Mineral supplement in Vitamin Retailer’s renowned Vity Awards.

What are the main benefits of magnesium glycinate?

Magnesium glycinate supports muscles, strong bones, and relaxation.* At 350 mg of magnesium per serving, Solaray’s Magnesium Glycinate also promotes a healthy heart and helps maintain healthy teeth and nerve function.*

Are there potential side effects when taking magnesium glycinate?

Magnesium glycinate is generally well-tolerated, even for those with sensitive stomachs. Solaray’s formula includes black pepper extract to aid in gentle digestion.* However, taking more than the recommended dose may lead to mild side effects like diarrhea or stomach upset. Always follow the suggested serving size and consult your healthcare provider if you have any concerns.

How does magnesium glycinate compare to other forms of magnesium?

Magnesium glycinate may have a stronger impact than other types when it comes to relaxation. This form of magnesium is also highly bioavailable, meaning it’s more easily absorbed through your small intestine. Unlike magnesium citrate, magnesium glycinate generally has less of a laxative effect.

Can magnesium glycinate help with relaxation?

Yes, magnesium glycinate is often used for relaxation support.* Research indicates its relaxation benefits may be related to the mineral’s ability to help regulate certain neurotransmitters in the brain, resulting in a calming effect on the body.
