𝗔𝗖𝗛𝗜𝗘𝗩𝗘 𝗢𝗣𝗧𝗜𝗠𝗔𝗟 𝗛𝗘𝗔𝗟𝗧𝗛 – Magnesium is very important for the (energy) metabolic process of the body. It may help your body function optimally, supporting cardiovascular & heart health, which also helps boost exercise performance, a calm mood, and natural sleep.

Liquid Iodine: The body doesn’t naturally produce iodine, so it is an essential part of any diet. At particular risk for iodine deficiency are those on a vegan or vegetarian diet, or those pregnant and nursing. It is crucial during pregnancy, when the body requires greater amounts of iodine to support the developing fetus.

Multiple Benefits: Iodine deficiencies can lead to feeling fatigued and weak, dry and brittle hair, skin, and nails, and weight gain. Iodine is especially important for thyroid health, which regulates hormone production, which in turn plays an important role in metabolism, stimulating the immune system and moderating the central nervous system. Support your body with this essential micronutrient!

Vegan Formula: 250 mcg Iodine (as Potassium Iodide). Other Ingredients: Organic Vegetable Glycerin and Purified Water. The suggested serving of our Iodine Liquid Drops contains more than the recommended daily value for adults, except for those lactating. An individual’s iodine needs are impacted by diet. Consult with a healthcare professional to determine if supplementing iodine intake is the right choice for you!

MAXIMUM ABSORPTION & POTENT MAGNESIUM SUPPLEMENT: BioEmblem Triple Magnesium Complex features 300mg of three types of pure magnesium (Glycinate, Malate, Citrate). Each is chelate or highly absorbable for maximum bioavailability. Our formula is easy on the stomach and "non-buffered," meaning this blend isn't diluted with less expensive and less absorbable magnesium oxide.*

SUPPORTS CALMNESS & IMPROVED SLEEP: Magnesium, especially in mag glycinate form, is an essential nutrient that supports healthy muscle and nerve function. This can help relieve muscle cramps and soothe tension for a greater sense of calm and restful sleep.*

PROMOTES HEART HEALTH AND ENERGY PRODUCTION: As a cofactor in hundreds of enzyme reactions, magnesium, especially magnesium malate, supports the metabolism of nutrients for cellular energy production. Magnesium supplements also help maintain normal blood pressure and heart rhythm to support overall cardiovascular health.*
