Our doctors have sky-high standards for Parsley’s professional-grade supplements—but there are two that they can’t live without.
Bundled as Doctor’s Favorites, Magnesium Glycinate and Vitamin D3 with K2 are the ideal supplement combination to protect your immunity, support natural deep sleep, improve mood, and boost bone health.
- Combats the depleting effects of stress
- Relaxes tight, sore muscles
- Supports bone and blood vessel health
- Boosts immune function
Magnesium Glycinate:
- Non-habit forming for a natural deep sleep
- Combats the depleting effects of stress
- Relaxes tight, sore muscles
- Boosts production of antioxidants like glutathione
Stressed, sore, or sleepless? Magnesium could be the micronutrient you’re missing. Chronic stress, insufficient dietary intake, and age can all contribute to magnesium depletion, and because magnesium is necessary for the functioning of over 300 enzymes, when your stores are low, you may not feel your best.
Magnesium can relieve headaches, anxiety, sore muscles, and trouble sleeping and insomnia. It also aids in bone and heart health. Some types of magnesium can cause digestive stress, but Parsley’s magnesium glycinate is formulated to be gentle on your stomach while still allowing for maximum absorption.
Vitamin D3 with K2:
- Supports bone and blood vessel health
- Assists in a healthy heart system
- Boosts immune function
- Flavorless liquid with easy-to-use dropper
Even if you live in a sunny climate, if you spend the majority of your day inside, like over 42% of Americans you could be deficient in vitamin D.
Vitamin D is a crucial nutrient because it helps regulate your immune system, aids in calcium absorption, and may play a role in mood regulation. Vitamin D3, also known as cholecalciferol, is the best supplemental form of vitamin D because it has been shown to be the most effective in raising and maintaining vitamin D levels in the blood.
When combined with vitamin K2, vitamin D3 helps move calcium into your bones, which prevents it from forming deposits in your blood vessels. Together, they’re your best defense against infection, osteoporosis, dementia, and type 2 diabetes.
Magnesium Glycinate: Magnesium bis-glycinate is designed for maximum absorption. Unlike other formulations, magnesium bis-glycinate is absorbed via a mechanism similar to that used by amino acids; it is not dependent on stomach acid for absorption. This formula supports muscle relaxation and nervous system health.
Vitamin D3 with K2: Vitamin D is in the form of vitamin D3, suspended in medium chain triglycerides formulated for best absorption alongside vitamin K2, and mixed tocopherols. Vitamin K2 is in the form of Menaquinone-7 (MK-7) for improved utilization by the body.
One drop contains: Vitamin D (as Vitamin D3) 1,000 IU. Vitamin K (Vitamin K2 as MK-7) 10 mcg.
Other Ingredients: Medium Chain Triglyceride Oil, Mixed Tocopherols.
Potential Interaction: As vitamin K interferes with the effect of anticoagulant drugs (like Coumadin or Warfarin), the concurrent use of these agents should be avoided
Magnesium Glycinate:
120 tablets per container.
Take 2 servings daily, or as directed by your healthcare provider.
Vitamin D3 with K2:
1 drop / 1000 IU
Take 2 to 10 drops daily or as recommended by your healthcare practitioner. Put the drops in water or other cool beverages, in food, or directly into your mouth.
What do we mean when we say that Parsley Health supplements are “professional grade”?
Like prescription drugs, supplements are powerful tools whose safety, quality, effectiveness, and relevance should be taken seriously.
At Parsley, our doctors are trained in prescribing high-quality supplements that are indicated to work for the conditions they support, like treating microbial imbalances in the gut, addressing nutrient deficiencies, or balancing blood sugar. We are highly selective and cautious in prescribing supplements, which are formulated with vitamins, minerals, nutrients, and botanicals in their most digestible and effective form. We often find they are more effective than conventional drug therapies alone.
We call Parsley-branded supplements “professional grade” because they’re third-party tested for quality and purity by reliable NSF- or USP-certified manufacturers in the U.S. They are manufactured at cGMP-compliant facilities, meaning the facility must meet requirements set forth by the FDA.

Was this helpful? - Laurel H.Verified BuyerReviewingVitamin D3 + K2Rated 5 starsFor me, your D3 was a lifesaver!
I had extremely low D3 & didn't know why I was depressed and exhausted. A normally upbeat person, I knew something was wrong and talked with my Nurse Practitioner. Luckily, she was knowledgeable enough to include D3 in with the blood tests that she ran. Indeed, she was spot on in her assessment. After getting my D3 up to a normal level with mega doses, she recommended you site & product - she uses it too. I take 11 drops a night and will never go without again. Thank you for producing such a wonderful - and lifesaving - product.

Great supplement, I notice a huge difference in sleep quality on nights I don't take it.

My doc recommended this magnesium. I've tried other brands and other types. This is the only one that helps me get to sleep and STAY asleep. I'm no longer waking up at 3 or 4 am and wired until 5 and a zombie the next day. Im actually getting 6-8 straight hours of sleep again. And WOW. What a difference it's making. Oh -- and no GI side effects thankfully.
