- MAS Iron
- MAS Recovery
Ingredients Clinically Shown in Over 75 Studies To Increase Ferritin More Than Generic Iron Supplements
Chelated iron, such as the iron bisglycinate in MAS Iron, is iron bound to two molecules of the amino acid glycine.
This form improves absorption because the two molecules of glycine block dietary factors like fiber from interfering with absorption.
The bisglycinate form is also more soluble, which translates to better absorption, which in turn decreases gastrointestinal side effects like constipation and stomach upset.
What does the science say about iron bisglycinate?
- A study in 100 anemic patients compared 120mg iron sulfate to 120mg, 60mg, and 30mg doses of iron bisglycinate daily for one month.
- 60mg iron bisglycinate for four weeks provided the best dose response in terms of elevating hemoglobin and serum ferritin (a protein that enhanced iron storage).
- The 120mg dose of iron bisglycinate resulted in 50% fewer GI side effects compared to the same dose of iron sulfate.
- A randomized, crossover study of the tolerability of iron bisglycinate versus iron sulfate found significantly more subjects preferred the bisglycinate form because it was less likely to cause GI upset.

Alpha-GPC is a choline-containing phospholipid. When ingested, alpha-GPC is rapidly absorbed and easily crosses the blood-brain barrier.
It is most well-known as a nootropic for cognitive-enhancement purposes. However, research has also shown it can enhance the absorption of iron.
- One study demonstrated that taking Alpha GPC with a traditional iron supplement quintupled the absorption of iron.
- In another study, Alpha GPC was shown to increase iron absorption from foods.

Vitamin C is perhaps one of the most-well known vitamins and minerals to help enhance iron absorption.
- In one study, adding just 63 mg of vitamin C to a meal rich in nonheme iron yielded a 2.9-fold increase in iron absorption.
- Studies have also shown the vitamin C can help enhance the absorption of iron when consuming calcium-rich meals (which has be shown to inhibit iron absorption).
The mechanism behind Vitamin C working so well to enhance iron absorption appears to be that it captures non-heme iron and stores it in a form that your body can absorb more easily.

BioPerine is a regulated black pepper extract containing 95% piperine.
BioPerine has been shown in research to enhance the absorption of several nutrients and other supplements.
Specifically when it comes to iron absorption…
- BioPerine benefits cardiovascular function by increasing the uptake of iron supplements as much as 30%.
- Researchers believe this is because BioPerine enhances the bioavailability of iron supplements.
BioPerine is a great example of the cutting-edge ingredients found in MAS Iron you won’t find in traditional iron supplements.

Vitamin B6 is needed for red blood cells to form and it’s needed for iron to convert into hemoglobin.
Thus, low levels of B6 can cause anemia and many other health problems.
Studies have also found that Iron and vitamin B6 together increase hemoglobin levels more than iron only.

Blood loss is one of the primary causes of iron deficiency. And given B12 is required for the production of red blood cells, a deficiency in Vitamin B12 can lead to a deficiency in Iron.
Supplementing with B12 can help negate any impact of low vitamin B12 levels on your iron levels.
The post-workout recovery product designed specifically for the needs of endurance athletes
Waxy Maize is a complex starch derived from non-GMO corn. Its lower blood osmolarity rate and higher molecular weight means it can be directly absorbed by the intestines after a workout at almost double the rate of traditional carbohydrates (cite).
Quicker absorption is critical for a number of reasons.
First, the faster you can get glycogen to your muscles post workout, the sooner the recovery process can begin.
Numerous studies have established that adequate carbohydrate intake following exercise is essential to promote muscle glycogen recovery (cite).
Second, by-passing the stomach means it’s waiting to be digested, potentially creating stomach issues that many endurance runners suffer when trying to eat post-workout.
Finally, waxy maize has also been shown to serve as an “uptake agent” that maximizes the absorption of other supplements such as protein and creatine.
With carbohydrate replenishment being critical to post-workout recovery, we wanted to include the most cutting-edge and effective post-workout carbohydrate source available.
Whey protein is the highest quality and best-absorbed protein for athletes because it’s highly bioavailable and contains a complete amino acid profile.
Numerous double-blind studies have shown that supplementing with whey protein after a workout enhances total body anabolism and improves numerous acute markers of recovery (cite).
Leucine is an amino acid best known for its role in promoting recovery from exercise because it’s the anabolic trigger of muscle protein synthesis.
Research has shown that taking whey protein combined with a high dose of leucine (5g) can enhance protein synthesis at the same rate as four times as much whey protein (cite).
This is why it’s ideal to include in a recovery product for endurance athletes.
Using leucine to boost protein synthesis while reducing the total amount of whey protein helps keep the gastric emptying response quick and can eliminate potential stomach issues associated with high whey intake.
In addition, studies have shown that supplementing leucine with carbohydrates post workout boosted muscle glycogen values by 14% compared to just carbohydrate alone, despite using less total overall carbohydrate (cite).
Older adults also exhibit a blunted muscle protein synthesis response compared to younger adults. Recent research has suggested that the reduction of muscle protein synthesis can be overcome by consuming greater quantities of leucine (cite).
The performance-enhancing effects of creatine are irrefutable and among the most widely researched of all natural supplements.
In regards to recovery in particular, creatine has been shown in the literature to…
✔ Reduce oxidative stress biomarkers after aerobic exercise (cite
✔ Reduced cell damage, muscle soreness and inflammation after running 30k (cite)
✔ A decrease in muscle damage and an improvement in muscle function after exercise (cite)
L-carnitine is an amino acid found mostly in meat and dairy products. L-tartrate is salt used to stabilize and deliver the L-carnitine.
In regards to recovery, L-carnitine L-tartrate has demonstrated…
✔ The ability to enhance recovery by reducing the amount of exercise-induced muscle tissue damage [cite].
✔ To assist in recovery from high-repetition exercise by reducing plasma markers of catabolism (cite)
✔ To improve blood flow and the delivery of oxygen to muscle tissue during and after exercise [cite].
Ashwagandha is an adaptogenic herb also known as Indian Ginseng or Winter Cherry.
Adaptogens are compounds with phytonutrients that help to regulate the body’s metabolism in times of physical or mental stress.
Ashwahandha can help promote recovery by reducing the amount of cortisol, often called the stress hormone, in the body.
Cortisol is a catabolic hormone, meaning it breaks down muscle and also causes a decrease in testosterone.
Ashwagandha has been shown in the literature to…
✔ Decrease serum cortisol by up to 27% [cite]
✔ Increase total testosterone by 17% (cite)
✔ Significantly reduce exercise-induced muscle damage (cite)
