Not Ideal If
- Anyone under 18
- Pregnant or nursing women
- People with phenylketonuria

Deep Dive
All Day You May covers amino signaling and all-day training support, but it does not supply a full creatine dose. Adding creatine fills the strength and phosphocreatine-recycling gap for a more complete daily performance stack.
Take creatine daily; use alongside or separate from All Day You May
This is the ideal stack if you want session intensity plus all-day amino support. A pre-workout handles acute energy and performance, while All Day You May handles amino coverage and hydration without adding more stimulants.
Pre-workout 20-30 minutes before training; sip All Day You May during training
All Day You May is not a pump formula, so pairing it with a dedicated nitric oxide product gives you blood-flow support plus leucine-heavy amino support in the same session. This is especially useful for high-volume bodybuilding sessions.
Pump product pre-workout; All Day You May intra-workout or between meals
If your training volume is high enough to justify an all-day amino product, your joints and connective tissue are often the next limiting factor. This pairing broadens support from muscular recovery to structural durability.
Take Joint Defender daily with meals; use All Day You May around training or between meals
Best choice if you specifically want a leucine-dominant 10:1:1 BCAA profile with stim-free all-day use.
A more modern intra-workout likely wins on overall formula sophistication and broader clinically aligned support.
Better fit if you want a more complete EAA and hydration-led intra formula rather than a leucine-heavy BCAA approach.
Different roles: Full As F*ck wins for pump, while All Day You May wins for all-day amino support.
Clinical Dosing
Full Product Description Article
5% Nutrition All Day You May is a leucine-heavy amino and recovery formula designed around one core idea: keep muscle support “on” throughout the day, not just around a single workout window. At its center is a 6,000mg branched-chain amino acid complex in a 10:1:1 ratio, which translates to roughly 5g leucine with about 500mg each of isoleucine and valine. That matters because leucine is the primary amino acid signal for muscle protein synthesis via direct activation of the mTOR pathway. The 2.5-5g clinical range for leucine is where research consistently shows meaningful anabolic signaling, and this formula lands right at the top end for leucine itself. In practical terms, that means this product is built to help preserve muscle during long gaps between meals, training, or dieting phases.
Isoleucine and valine do more than just fill out the label. Isoleucine supports glucose uptake into muscle, which can be useful during training and long activity sessions, while valine competes with tryptophan at the blood-brain barrier and is associated with reduced central fatigue in BCAA research. The limitation is important: BCAAs are not a full replacement for complete dietary protein or a fully dosed EAA formula. That brings us to the formula’s small 155mg essential amino acid blend. It includes phenylalanine, threonine, histidine, and methionine, but at this dose the blend is far below clinically meaningful standalone EAA support. It adds completeness, not major firepower.
The more interesting secondary system is the 2,800mg conditionally essential amino acid blend: L-glutamine, L-carnitine L-tartrate, and N-acetyl cysteine. Glutamine is the most abundant conditionally essential amino acid in the body and is especially relevant for gut lining cells and immune cells under stress, though research does not support it as a major muscle-building ingredient in healthy athletes unless doses are much higher, usually 5-15g. In this product it is better viewed as general recovery support. L-carnitine L-tartrate is a smart inclusion for training support because this form is commonly used in sports nutrition for recovery, tissue repair, and exercise stress management. NAC adds antioxidant support as a glutathione precursor, helping the formula cover oxidative stress rather than just amino delivery.
The support blend adds 960mg of taurine, raw coconut water concentrate, alpha-hydroxyisocaproic acid, bromelain, and blueberry powder. Taurine is useful for cell hydration and muscular function. Coconut water concentrate adds electrolyte support. HICA, a leucine metabolite, is commonly positioned for anti-catabolic and soreness support. Bromelain supports protein digestion and may help with post-training inflammation management. The Intra-Cellular Buffer Blend contains 1,500mg total of creatinol-O-phosphate and beta-alanine, with beta-alanine fixed at 800mg. That beta-alanine dose is well below the 3.2-6.4g daily range used to meaningfully raise muscle carnosine, so it is not a clinically complete buffering dose on its own. Still, combined with creatinol-O-phosphate, it supports the product’s “all day performance support” positioning.
Transparency is mixed. The formula discloses the total weight of each blend, but not every individual ingredient dose within those blends. That is more informative than a fully hidden proprietary system, but still limits true clinical evaluation of glutamine, taurine, carnitine, NAC, HICA, and creatinol-O-phosphate. The biggest strength here is clear: you are getting a genuinely high-leucine BCAA serving, not a weakly dosed amino product. Day 1, expect a refreshing stim-free amino drink that can make training and between-meal periods feel more supported and less flat. Over 2-4 weeks, the benefit is less about a dramatic acute effect and more about consistently better workout support, hydration, reduced perceived breakdown during dieting or high-volume phases, and easier daily amino intake.

Leucine is the primary branched-chain amino acid responsible for activating mTOR, the intracellular signaling hub that initiates muscle protein synthesis. While all essential amino acids are required to build new muscle tissue, leucine is the trigger that turns the process on. That is why a formula delivering roughly 5g leucine carries more anabolic significance than a generic low-leucine amino drink. In practical sports nutrition, leucine dose is one of the clearest examples where amount matters as much as ingredient presence.
BCAAs are unique among amino acids because skeletal muscle can oxidize them directly during exercise. Leucine supports anabolic signaling, isoleucine supports glucose uptake into muscle, and valine participates in central fatigue modulation through competition with tryptophan transport. This does not make BCAAs a replacement for complete protein or full EAAs, but it explains why they remain useful in fasted training, long sessions, and dieting phases where muscle preservation becomes a priority. Their value rises as energy availability and meal frequency fall.
Glutamine is often oversold as a muscle-building ingredient, but the better-supported physiology points elsewhere. It serves as a major fuel source for enterocytes in the gut and immune cells during physiological stress, and the body can synthesize large amounts under normal conditions. In healthy athletes, isolated glutamine is not strongly supported for increasing muscle mass, but it can still make sense in formulas targeting recovery stress, gut support, and heavy training demands. Its best use is supportive, not headline-driving.
Beta-alanine raises intramuscular carnosine, a dipeptide that buffers hydrogen ions produced during high-intensity exercise. The practical outcome is improved tolerance to the burning fatigue that builds during repeated hard efforts. Research-backed effects typically require 3.2-6.4g daily over multiple weeks, which is why 800mg is better described as supportive inclusion than a full loading strategy. The mechanism is excellent; the question is always whether the dose is enough.
Hydration support ingredients often determine whether an intra-workout formula feels merely flavored or genuinely functional. Taurine helps regulate cellular osmolarity and muscle function, while coconut water concentrate adds a naturally electrolyte-associated hydration component. These ingredients do not create dramatic sensations, but they improve the context in which amino acids are used: a better-hydrated muscle cell is better positioned to perform, contract, and recover. In a product designed for sipping across a session, that matters.
