Minerals

Thorne offers a choice of nutritional supplements to support an active lifestyle and to achieve goals – no matter what they are. Although there are many different paths to peak performance, what remains constant is meeting basic hydration and electrolyte needs, maintaining the body’s normal

inflammatory response, and getting enough sleep. Just as fueling activity is important, so is the importance of maximizing recovery from that activity. Implementing an effective recovery strategy involves accounting for the metabolic demands of training, rehydrating, and supporting recovery from injury. Many Thorne products offer supplementation to meet these needs. Thorne's Sports Performance products are trusted by athletes and health-care practitioners to allow individuals to personalize their pre- and post-workout routine based on their specific needs.*

    I have been taking these for few months and I can say I like everything about these.
    - They don't cause constipation like other brands
    - They are small capsules
    - No after taste
    - Good price for the number of pills in the bottle

    I take them at night with a tablet of vitamin C for better absorption (as recommended by my naturopath).

    This product saved my life. I always thought it was possible I was anemic, but it wasn't until I tried this supplement that I knew for sure. I've taken iron before but didn't feel a change. With these, after a few days I had less pain in my body, I was able to breathe while working out, I had more energy and less fair falling out.i had no digestive issues either but I take it with food and liposomal vitamin c since they work together. I also take other supplements like B12 and magnesium and I do think they all work together very well. Thank God for companies like thorne 🙏 give it a try, you won't regret it.

    I've been struggling with low iron on and off for the last year, mostly because the generic brand supplements I was taking were high dose, low absorption, and generally made me feel like garbage and gave me HUGE GI discomfort. these things seem to be low dose with high absorption, and I'm feeling much better within two weeks of taking them - I feel stronger, more energetic, and am handling cardio exercise like a champ. they're really easy to swallow, the flavour is the best you could ask for of an iron supplement, and really considering you'll only need 1 a day, they're quite affordable. can only recommend!
