Let’s face it: PMS is awful. The bloating, the cramps, the crankiness, the exhaustion, and let’s not discuss the crying — it’s terrible. But it doesn’t have to be that way. Greens First® Female PMS supports the management of most common symptoms of PMS. Best of all, the ingredients we use are all-natural and clinically tested for safety and effectiveness.

But let’s not just issue a broad claim like that without backing it up. There’s real science behind the ingredients in Greens First® Female PMS. Let’s look at two key ingredients and how they work to make your period a little less horrible.

Magnesium for PMS

Magnesium is a naturally occurring mineral found in common dietary sources such as bananas, almonds, pumpkin seeds, and dark chocolate. Magnesium deficiency has been implicated as a causative factor in some symptoms of PMS, and studies have noted lower intracellular magnesium concentrations among women with more severe PMS symptoms.

A 2007 study by Quaranta and colleagues1 examined the value of magnesium supplementation in a sample of women between 18 and 45 years old, who reported both a regular menstrual cycle (25–35 days) and demonstrable PMS symptoms (determined using a PMS self-evaluation questionnaire). Forty-one women were given a modified-release magnesium tablet over three menstrual cycles, beginning 20 days after the start of their last menstrual period and continuing until the start of their next menstrual period. PMS symptom severity improved during magnesium treatment—both as assessed via questionnaire (35.1% decrease) and via patients’ recorded diaries (33.5% decrease). Magnesium supplements were well tolerated in all but one case.

Nutritional support using magnesium supplementation helps your own body’s natural mechanisms relieve the most common and uncomfortable symptoms of PMS.

Why Magnesium Oxide?

Each dose of Greens First Female PMS Formula contains 300 mg of magnesium oxide. Magnesium is a mineral that is absorbed by the body at different rates, depending on the compound used, as well as on the size of the molecule to which the magnesium is bonded. Magnesium oxide is a smaller molecule, and as such is not as easily absorbed as, say, magnesium citrate—however, it has the highest proportion of magnesium per weight, so it can actually yield more elemental magnesium per dose than a comparable dose of magnesium-citrate. Magnesium oxide also avoids the laxative effect caused by magnesium citrate compounds.

Quercetin for PMS

Quercetin is a plant-derived flavonoid found commonly in apples, onions, and red wine, and has been shown to have anti-inflammatory and cardiovascular benefits such as blood-pressure reduction. In combination with other dietary supplements, it can reduce the most severe symptoms (such as cramping and pain) commonly associated with PMS. Quercetin also contains powerful antioxidants. It can help to reduce inflammation, boost immunity, and counter the other negative effects of free-radicals in the body.

Why Quercetin 98% Dihydrate?

A highly purified powdered form easily processed by the body. It has shown to inhibit the ovarian cancer cell growth, depending on the dose. Dihydroquercetin derivatives have also shown action against human breast cancer cells. Greens First uses an easily absorbed form of quercetin that is both gentle on the system and effective in providing relief of the monthly pain and cramping associated with your menstrual cycle. A 2010 study by Bhutada and colleagues2 also indicated that quercetin may have beneficial effects on mood, including the reduction of anxiety and depression.

With the combined effects of symptom reduction, nutritional support, and antioxidant activity, it’s easy to see why Greens First Female PMS Formula should be your go-to support for relief of common PMS symptoms. Give yourself a break and give it a try.
