Who is OptimalStack for?
OptimalStack was developed for Olympians and Pro Athletes but is now available for anyone who wants to build muscle and live better.
-
Elite
Competitive athletes invest heavily in training and nutrition to perform and win at the highest levels.
OptimalStack's synergistic combination of HMB and Creapure® creatine monohydrate provides a significant increase in power generation, peak power, maximum speed (anaerobic), maximal oxygen uptake and maximal load (endurance). -
Fitness
Getting serious about your fitness includes not only regular exercise and adequate rest but also proper nutrition to reach your goals. For many, meal planning and counting "macros" has become essential in reaching their fitness goals.
OptimalStack provides an incredible edge in physical performance, allowing you to train harder, train longer, and recover better. -
Health
Muscle mass generally declines with age, starting in the 30s and accelerating after 60. Individuals can loseup to 3% to 8% of muscle mass per decade after the age of 30 with a loss of around 1% per year after age 60.*
OptimalStack contains 3g of HMB/D3 per serving which has been clinically demonstrated to both stimulate muscle growth and reduce muscle loss.

HMB and Creatine
Supplementing with HMB alongside creatine surpasses the performance enhancement achieved by using creatine alone, rendering it the optimal performance stack to incorporate into your regimen.

The OptimalStack
Besides protein, creatine ranks as one of the most extensively researched and efficacious supplements for athletes. Creatine facilitates heightened training intensity by furnishing increased energy during workouts. Nevertheless, this heightened intensity often results in elevated muscle damage. HMB, however, has demonstrated its ability to diminish muscle breakdown, thereby expediting recovery post-exercise. By reducing muscle breakdown, HMB enables more frequent training sessions, thereby amplifying training adaptations such as strength and lean body mass. The combination of creatine and HMB accelerates progress towards fitness goals, making this the ideal performance stack.
Purest Ingredients
Creapure® is the patented gold-standard in creatine made in Germany. myHMB® is the original patented form of HMB produced in a dedicated facility by the innovators. myHMB® has as recently attained the status as a USP-verified ingredient.

Synergistic Effect on Lean Muscle Mass
A three-week study examined whether creatine and HMB have similar or different effects on increasing lean body mass and strength in individuals undergoing resistance exercise training. Results showed that all groups experienced gains in lean body mass, with the creatine and creatine/HMB groups showing significant increases compared to the placebo group. The findings also suggest that creatine and HMB have additive effects on lean body mass and strength, potentially acting through different mechanisms. Jówko et al., 2001

Frequently Asked Questions
What is Creapure®?
Quality, purity and safety with Creapure®
Creapure® is the brand name for pure creatine monohydrate, exclusively produced by Alzchem Trostberg GmbH at their specially-designed production facility in Trostberg Germany. Most creatine on the market today is sourced from cheap, Chinese manufacturers.
Creapure® is the most widely studied form of creatine and is proven to be safe and effective. OptimalStack purchases Creapure® directly from Germany and uses it under license so that you can be assured that you are using one of the best and most reliable products on the market.
Creapure® is vegan and exclusively manufactured by chemical synthesis. Raw materials and intermediates are not derived from animal or herbal products resulting in no traces that may have originated from animal or herbal byproducts.
The production of Creapure® is FSSC 22000 certified, a quality standard recognized by the “Food Safety System Certification”
What is myHMB®/D3?
HMB is naturally produced in our bodies during the metabolism of the essential amino acid leucine. Leucine is a part of the food chain – we consume it every day in foods like soybeans, beef, alfalfa, and fish.
Some proteins have more leucine than others, however the body only converts about 5% of leucine to HMB so it is difficult if not impossible, to consume enough protein through supplementation or a healthy diet alone to achieve the effective amount of HMB your body needs.
What is NSF Certified for Sport®?
Don't be fooled by other brands that claim to be 3rd-party tested but don't disclose who does the testing, what they are tested for, and if they even passed the "tests!"
OptimalStack is not only EXTENSIVELY tested by multiple third-party, independent laboratories, every batch of OptimalStack have earned the prestigious NSF Certified for Sport® certification for quality and safety by the most reputable, independent third-party testing and certification organization in the world: NSF International.

What does the clinical research about creatine and HMB/D3?
Effect on Quality of Life and Handgrip Strength by Dynamometry of an Enteral Specific Supplements with Beta-Hydroxy-Beta-Methybutyrate and Vitamin D in Elderly Patients
In this 12-week study, 35 subjects with the mean age of 79.1+7.5 years were examined to see how the nutritional intervention of HMB and Vitamin D would effect strength and quality of life. The results from the study confirm the beneficial effects on weight, handgrip strength, some domains of quality of life and Vitamin status of an enhanced enteral formula with Vitamin D and beta-hydroxy beta-methylbytyrate (HMB) in elderly patients.
Effect of Calcium β-Hydroxy-β-Methylbutyrate (CaHMB), Vitamin D, and Protein Supplementation on Postoperative Immobilization in Malnourished Older Adult Patients With Hip Fracture: A Randomized Controlled Study
A clinical study examined how the combination of myHMB, Vitamin D3, and protein could help improve recovery after orthopedic surgery for a hip fracture. Patients supplementing with the myHMB + Vitamin D3 , and protein cocktail were more mobile on days 15 and 30. The patients were also found to have significantly increased strength on day 30.
Long-term Effects of Calcium beta-Hydroxy-beta-Methylbutyrate and Vitamin D3 Supplementation on Muscular Function in Older Adults With and Without Resistance Training: A Randomized, Double-blind, Controlled Study.
In this year-long study of 117 older adults (≥60 y) were studies in four treatment arms: 1) 3 g HMB plus 2,000 IU Vitamin D per day with exercise; 2) 3 g HMB plus 2,000 IU Vitamin D per day with no exercise; 3) Placebo with exercise; and 4) Placebo with no exercise. All participants had baseline Vitamin D levels from 15-30 ng/mL, which would be considered insufficient for optimal physical functioning. HMB plus Vitamin D supplementation significantly increased lean mass within the non-exercising group at 6 months. Additionally, in the non-exercising groups knee extension peak torque (60⁰/s) was significantly improved at 3 months in the HMB plus Vitamin D group compared with the non-exercising placebo group. A functional index of the physical tests, which included handgrip strength, get up, and get up and go measurements, showed that HMB plus Vitamin D resulted in a significant increase in the functional index at 3, 6, and 12 months of the study. The authors concluded that HMB plus Vitamin D could enhance muscle strength and physical function in older adults even without engaging in an exercise program.
Vitamin D status affects strength gains in older adults supplemented with a combination of β-hydroxy-β-methylbutyrate, arginine, and lysine: a cohort study.
This year-long retrospective study in elderly adults demonstrated that a nutrient mixture of HMB, arginine, and lysine alone was effective in improving body composition regardless of vitamin D status, but accompanying strength increases were observed only when participants also had adequate vitamin D status indicating a synergistic effect between the HMB, arginine, and lysine and vitamin D.
