Biotin belongs to the group of vitamins called the vitamin B complex. Biotin (Vitamin B7) is found in some foods, including egg yolk, liver, and yeast.

• Is Biotin safe for pregnant women?

If you are pregnant, nursing, taking any medications, planning any medical or surgical procedure, have any medical condition, or are planning to undergo any clinical lab testing, consult your doctor or health practitioner before starting any supplement regimen, including Biotin. Some supplements, especially those that contain Biotin, may interact with certain medications and/or interfere with certain lab tests. It is advisable to consult your doctor before using biotin doses above 2,500 mcg per day.

• What are the daily recommended amounts of magnesium?

Everyone needs magnesiuim. It acts as a cofactor or activator for more than 600 enzymes and supports vital functions throughout the entire body! So we think its pretty important but most people do not get enough of this good stuff on a daily basis. So, generally, experts agree that we should be taking getting more of it. Luckily BEST has you covered with our highly absorbable form of Magnesium. Here are the Recommended dietary allowance (RDA) of Magnesium based on sex and age:
Males, 19 - 30 years: 400 mg
Males, 31+ years: 420 mg
Females, 19 - 30 years: 310 mg
Females, 31+ years: 320 mg
Females, 19 - 30 years, pregnant: 350 mg
Females, 31 - 50 years, pregnant: 360 mg
Females, 19 - 30 years, lactating: 310 mg
Females, 31 - 50 years, lactating: 320 mg
Always consult your nutritionist or doctor before consuming any supplements.

• How much magnesium is too much?

Excessive magnesium from food does not necessarily cause a health risk in healthy people because your body uses what it wants and then pees out the rest. However, high doses of poorly absorbing magnesium from dietary supplements or medications often result in the runs that can be accompanied by cramps and vomit, due to the unabsorbed salts pulling water into the intestines and causing the urge to poop. Yikes! The forms of magnesium that most commonly cause these issues include magnesium carbonate, chloride, gluconate, and oxide. Magnesium glycinate does not tend to cause stomach issues.

• When is the best time to take magnesium?

We recommend taking BEST Magnesium Glycinate in the evening or approx. 30 min before bedtime because magnesium glycinate has the added benefit of relaxing muscles, giving bedtime vibes.

• How long will it take to start seeing results from BEST Magnesium Glycinate?

It depends on your individual levels of magnesium deficiency, biochemistry and the type of magnesium you take because not all magnesium forms are created equal. For example, BEST Magnesium glycinate has been shown to be better absorbed than others, which means that your body will utilize it more quickly giving you its benefits sooner. Some of our customers have noticed immediate effects, while others have said it can take days or weeks. The most important thing is to remember that your body will feel improvements before you will notice them. Generally speaking, it can take 2-3 weeks of consistent supplementation to notice positive results from any dietary supplement but may take a few months of consistent supplementation for your body to reach biochemical equilibrium at maximum.

• Who should take Magnesium?

Everyone needs magnesium. There over 300 enzymatic reactions that require it but over half of U.S. adults (54%) don’t consume enough in their daily diet, which is why supplementation may be important for many people. The daily recommended magnesium intake is 410 +/- 10 mg/day for men and 315 +/- 5 mg/day for women.

• Can I take BEST Magnesium with BEST Multivitamins? Will I be taking too much Magnesium?

This can lead to deficiencies and potential health concerns.
