These Are the Best Magnesium Supplements | Rhonda Patrick, Ph.D.

Published 2024-03-19
In the landscape of essential nutrients, magnesium is a giant. Despite magnesium's critical functions, nearly half of people in the U.S. don't get enough, primarily due to diets lacking in magnesium-rich foods like dark leafy greens, nuts, and seeds. That's where supplementation can help.

In this video, expect to learn

• The upper safe limit for daily supplemental magnesium intake
• The #1 sign of excessive magnesium supplementation
• Why you should divide up magnesium supplement doses throughout the day
• The most bioavailable (and most effective) magnesium supplements
• Whether or not magnesium threonate is better at crossing the blood-brain barrier
• Why magnesium threonate shouldn't count toward your RDA goal
• Rhonda Patrick's magnesium supplement regimen (doses and brands)

  • Magnesium glycinate has helped me sleep so solid/straight through the night. ALSO, my anxiety levels are almost gone!! An incredibile supplement!! 😊 I take 315 mg per day.
  • @Kerfufflekitten
    I used to have chronic cramps for years and have been to several doctors that never were able to help me, then I started putting a couple tsp of mag glycinate and potassium citrate in my 100 ounce cup before leaving for the day and it has literally change my life.

    When I was in training as psychologist, my supervisor spoke about the benefits of magnesium for a number of reasons, e.g. reduced anxiety, stress and overall well-being. I followed his recommendation and the results were tangible. Mind you, that was in the year 2000, like almost 25 years ago. Btw, that's the value of a great practitioner, whether medical or psych, that they strive to know what is going on outside the box. Thank you, Martin Kleinschnitger, and shout out to you, Dr Rhonda. Great minds always think alike. 👍🙏

    Not sure if Rhonda actually reads these comments or answers questions, but my doctor prescribed magnesium for high blood pressure for me and it has really helped.
  • @lh2000
    I noticed that after taking Magensium L-Threonate that my dreams have become a lot clearer and vivid… it was quite obvious and immediate
  • @Digbite
    The stuff changed my life. Anxiety dulled so I could sleep. With sleep the anxiety stopped creeping in and so on.
  • @brent-sherman
    I've been taking magnesium threonate along with apigenin and l-theanine before bed for about a year now and my sleep is on a whole different level. Wonderful, deep sleep.
  • Dr Patrick, you are the best at explaining all these things and you have been a HUGE influence in my life / quality of life!!! Keep up the great work and research!

    Love your videos. I've shared the one on all-cause mortality and cancer linked to deficiencies in micronutrients as widely as I can including to specialists, registrars, GPs, medical executives, nurse practitioners, CNCs.. pretty well everyone I can. One thing I think is worth pointing out is that when Rhonda talks about milligrams of magnesium, she is referring to "elemental" and NOT the salt value. In the case of Glycinate, for instance, to get 300mg of elemental magnesium, you need a 3000mg (3g) dose. I often find that people are taking a 500mg tablet of some salt (they usually don't know), thinking they are hitting RDA.. when in fact they might only be absorbing say 10-30mg, even less with sulfate or oxide.

    I am a shell shocked veteran, I got severe anxiety issues and I care about my health. I get my magnesium from epsom salt baths. My doctor complained that my magnesium levels were too high. In my not a professional but a fan of life hacking opinion, the actual fastest and best way to get a lot of magnesium to absorb fast is to eat eggs for dinner and the following morning do a workout and drink some coffee then take a cold bath with epsom salt in it while you are still sweating from the workout, an ice bath if you can tolerate it. Soak in the epsom salt for twenty minutes and then shower it off and wash with soap after, or if you are extremely magnesium deficient you can refrain from washing the salt off in the morning and just take a shower later at night to wash it off. I have seen no studies in books that say this, but it seems to me like, as your body excretes sodium, and potassium with sweat that the outward force of these metals through active diffusion in sweat, creates an ionic reactive force that will help pull magnesium through the skin and into the extracellular fluid of the hypodermis. Every action has an equal and opposite reaction, active diffusion one way can power diffusion in the other direction as well and this is a type of salt transport. I heard that absorption is better in cold than in hot baths, I know that egg protein is the best protein shy of milk protein to act as a dietary boost of active transport ligands, takes about 5 to 8 hours from eating to it to available in the blood.

    This is anecdotal, because I never had an identified baseline magnesium level, but once I increased my daily magnesium glycinate supplement intake to 400 mg (200mg in morning and at night), my lifelong headaches and migraines disappeared. This happened at age 55 (male). If the cause of my lifelong headaches was truly because of a simple magnesium deficiency, I wish I had started with 400 mg many years before. No change in lifestyle; no change in diet…it has truly been remarkable.
  • @tom7471
    Thank you for the clear and precise information given on magnesium supplements!
  • @travkatz
    what a great summary. thank you. worth my limited time to fully take this in.
  • @jhoang3671
    I love the clips from Dr. Rhonda Patrick. I dont have the time to listen through all the long forms. But this shorter ones are amazing.
  • @seti48
    Thanks, Doc. I like the way you get right to it without any long winded preamble. Precise and informative. Thanks again.
  • @PhoenixTTD
    From my anecdotal experience, I know that Magnesium L-Threonate Matein (Life Extension brand) does influence the brain. Every day I took it, I had lucid dreams that stopped when I used a cheaper brand of L-Threonate that was not "Magtein" and when I used Magnesium Glycinate. The effect was very strong like a drug. How much is getting into the brain and how healthy it is, I cannot say, but it is definitely doing something.
  • @JFImagery
    I had a problem with bad cramps in my legs, along with mysterious blood clotting in my legs. Since I have started using Magnesium Glycinate, the problems have gone away. I also take Electrolytes daily for the same issue. So glad to have discovered this...
