    Hello Jordan,

    I have two questions:

    1. Are choline and inositol effective at lowering blood pressure and / or helping to achieve favorable blood lipid levels?

    2. When one stops taking creatine, how long does it usually take for their body achieve a normal level of natural creatine production again?

    Thank you so much for your time!

    1) No

    2) About 4 weeks give or take.

    Thank you for the reply! I have one follow-up question:

    Does the average 4 week period vary with the duration of time one has supplemented with creatine (1 year vs 5 years).

    One more question related to creatine. What are the noticeable common effects when starting supplementing with it? Ability to do more reps with high intensity weight, better recovery between sets, both or something else?

    Also, how many are typically non-responders for creatine supplementation? In other words, no noticeable benefit is noticed.

    Not that I've seen, no.

    No "noticeable" effect is subjective, but the literature reports about 10-20% of folks who are "non responders" who already have very high creatine stores in their skeletal muscles. Still, improvements have been seen in some studies in this cohort.

    From the JISSN:

    "Nearly 70% of these studies have reported a significant improvement in exercise capacity, while the others have generally reported non-significant gains in performance [49]. No studies have reported an ergolytic effect on performance although some have suggested that weight gain associated with CM supplementation could be detrimental in sports such as running or swimming. The average gain in performance from these studies typically ranges between 10 to 15% depending on the variable of interest. For example, short-term CM supplementation has been reported to improve maximal power/strength (5–15%), work performed during sets of maximal effort muscle contractions (5–15%), single-effort sprint performance (1–5%), and work performed during repetitive sprint performance (5–15%) [49]. Long-term CM supplementation appears to enhance the overall quality of training, leading to 5 to 15% greater gains in strength and performance [49]. Nearly all studies indicate that "proper" CM supplementation increases body mass by about 1 to 2 kg in the first week of loading [19].

    The vast expanse of literature confirming the effectiveness of CM supplementation is far beyond the scope of this review. Briefly, short-term adaptations reported from CM supplementation include increased cycling power, total work performed on the bench press and jump squat, as well as improved sport performance in sprinting, swimming, and soccer [38,50-57]. Long-term adaptations when combining CM supplementation with training include increased muscle creatine and PCr content, lean body mass, strength, sprint performance, power, rate of force development, and muscle diameter [39,54-60]. In long-term studies, subjects taking CM typically gain about twice as much body mass and/or fat free mass (i.e., an extra 2 to 4 pounds of muscle mass during 4 to 12 weeks of training) than subjects taking a placebo [61-64]. The gains in muscle mass appear to be a result of an improved ability to perform high-intensity exercise via increased PCr availability and enhanced ATP synthesis, thereby enabling an athlete to train harder and promote greater muscular hypertrophy via increased myosin heavy chain expression possibly due to an increase in myogenic regulatory factors myogenin and MRF-4 [26,27,65]. The tremendous numbers of investigations conducted with positive results from CM supplementation lead us to conclude that it is the most effective nutritional supplement available today for increasing high-intensity exercise capacity and building lean mass.
