COLLAGEN COFFEE

COLLAGEN COFFEE (500 gram)

  • 18g protein and 100mg caffeine per cup
  • Made with Fairtrade Colombian Arabica Coffee
  • Types 1 & 3 collagen

WHAT IS COLLAGEN COFFEE?
Cast your mind back to 2014, Japan landed a space probe on a comet, Germany handed Brazil a 7-1 drubbing at the World Cup and BULK POWDERS® had just launched our first iteration of Complete Protein Coffee™. This was the UK market’s first experience of a protein coffee that didn’t require endless mixing, microwaving, further mixing and overall feelings of disappointment. When we originally brought this product to market, it was made with a heat-stable whey protein isolate that mixed instantly with hot water, which sadly got discontinued after a couple of years. We tried every single heat-stable whey protein that suppliers could throw at us, but sadly to no avail, Complete Protein Coffee™ was no more. Fast forward to 2019 and for better or for worse, a lot has happened. One thing falling in the ‘better’ category is Collagen Coffee becoming the latest offering in our ACTIVE FOODS™ range. It is made simply with Hydrolysed Collagen Peptides, Colombian Fairtrade Coffee and MCTs. On the surface it may just appear to be another protein coffee, however the beauty comes with how it mixes and tastes. All you need to do is add one 25g scoop to your favourite mug, pour over hot water from your kettle and let the powder dissolve. You’ll have a ready-to-drink protein coffee in seconds that provides 18g protein and 100mg caffeine, about the same as a regular high street coffee for a fraction of the price.

The hydrolysed collagen peptides in Collagen Coffee are composed of Type 1 and Type 3 collagen and are obtained from bovine hides. Our collagen has a particularly neutral flavour, making it suitable for use in this application. Collagen has a different amino acid profile to dairy proteins; instead of Tryptophan and Cysteine, it provides Hydroxyproline and Hydroylysine.

INFORMED BCAA™

INFORMED BCAA™ Apple & Blackcurrant (525 gram)

  • Massive 18g amino acids including 10g BCAA in an 8:1:1 ratio
  • Added Glutamine, AAKG, Alanine and Glycine
  • Banned substance tested under Informed Sport Programme

DESCRIPTION K-Pure
The challenge: “Ignore the costs and just create the very best BCAA supplement possible.” The result: INFORMED BCAA™

 

INFORMED BCAA™ is quite simply the Norway’s very best BCAA supplement, with a massive 18g amino acids per serving! It contains a whopping 10g of BCAA in an 8:1:1 ratio along with 2g Glutamine, 2g Arginine Alpha Ketoglutarate, 2g Alanine and 2g Glycine. This quantity, array and combination of amino acids is completely unrivalled across the entire sports nutrition industry. It’s well known that BCAAs, or Branched Chain Amino Acids are essential amino acids that comprise about 1/3 of the protein within our muscles. BCAAs must be obtained from our diet as our bodies are unable to synthesise them.

 

Now, you may be wondering what’s changed from our original Informed BCAA formula. For starters, it now tastes amazing. We revised and improved our original Orange & Mango flavour and added refreshing Summer Berry and Apple & Blackcurrant flavour offerings. Next, you may notice that INFORMED BCAA™ is now vegan-friendly and soya-free. We switched the sources of our Leucine to ensure that this product is now suitable for absolutely everyone.

 

Finally, you may wonder where and why the Nitrates and Ethyl Esters have gone from the formula. These were nice points of difference in our original formula, however, they gave the shake a very distinctive taste. They also led to a few reports of gastrointestinal discomfort, something you absolutely do not want distracting you when you’re training near your maximum potential. As a result, we are now able to offer you a world-beating formula with industry-leading doses. INFORMED BCAA™ is now also a taste-sensation.

 

INFORMED BCAA™ delivers an 8:1:1 ratio of BCAAs per serving from BCAA Nitrates. In addition, 2g Arginine Alpha Ketoglutarate (AAKG) has been added. Furthermore, there is 2g Glutamine, the most abundant amino acid in muscle tissue. 2g Alanine has been included in this remarkable formula as it is actually the second most abundant amino acid in muscle tissue. Finally, 2g Glycine has also been added. This exclusive world leading formula, combined with a gourmet taste and rigorous independent banned substance testing, really does create the best BCAA supplement possible! What's more, INFORMED BCAA™ is totally transparent – the exact form and quantity of each ingredient is declared, as opposed to inferior sources of ingredients and hiding behind proprietary blends where ingredient amounts are indeterminable. After all, you deserve to know exactly what you are putting into your body.

 

INFORMED BCAA™ | PREMIUM BCAA SUPPLEMENT
INFORMED BCAA™ delivers an 8:1:1 ratio of vegan-friendly BCAAs per serving. In addition, 2g of AAKG and 2g of Glutamine, the most abundant amino acid in muscle tissue, have been added. Furthermore, 2g Alanine has been included in this remarkable formula as it is actually the second most abundant amino acid in muscle tissue. Finally, 2g Glycine has also been added. It would have been easy to take the approach of other brands and crammed loads of amino acids into our formula at tiny, ineffective doses. Instead, we decided to dose seven amino acids properly and to give them to you in three delicious and original flavours.

 

INFORMED BCAA™ contains less than 1g Carbohydrate per serving and can be used intra-workout or even as a drink to sip on throughout the day, to ensure the muscles are topped up with amino acids.

 

INFORMED BCAA™ | A TASTE SENSATION
INFORMED BCAA™ is available in a new and improved Orange & Mango flavour, along with taste bud-tingling Summer Berry and Apple & Blackcurrant flavours. Months of hard work went in to blind tastings and constant revisions, until finally our in-house team of flavour technologists delivered what we believe to be industry-leading flavours. This was no small feat when you consider the array of high quality ingredients in the formula.

Tyrosine (500 gram)

Tyrosine (500 gram)

Tyrosine is a powerful aromatic amino acid that is a building block for dopamine, epinephrine, norepinephrine, and thyroid hormones. Tyrosine supplements are nootropics and adaptogens that help with performance during times of stress. Many people find that it helps significantly with fatigue from stress.
Tyrosine is a precursor to neurotransmitters, which include dopamine, norepinephrine, and epinephrine. Elevated levels of tyrosine increase the production of these neurotransmitters when our bodies need more of them. However, these situations have to be sufficiently challenging to require the extra release of neurotransmitters and subsequent depletion of these neurotransmitters. To maintain optimal neural performance, tyrosine supplementations prevented the neurotransmitters from depleting 

1) Tyrosine Replenishes Cognitive Resources Used in Memory
Tyrosine supplements restored certain cognitive resources used to increase working memory. Working memory is responsible for the continued updating and maintenance of memory. Studies showed that tyrosine only replenished certain cognitive resources when the resources get used up, so only challenging situations that require the use of these cognitive resources see an enhancement of the cognitive resources

2) L-Tyrosine Is a Building Block of Thyroid Hormones
Thyroid hormones control energy production in the body, aiding in the repair and renewal of damaged cells, while increasing resistance to constant stress. In a bird study, chicks with induced tyrosine deficiencies had much lower levels of T3 and T4, common thyroid hormones, in their blood. Birds that were given only phenylalanine supplements, which is the direct precursor to tyrosine, did not gain as much weight as birds given phenylalanine plus tyrosine supplements. This evidences that tyrosine supplementation helped in the growth of the chicks. In rat studies where certain rats were put under constant stress, the stressed rats suffered from reductions in T3 and T4 thyroid hormones. This is due to a decrease in the enzymes’ thyroid peroxidase and oxidase, which are crucial for thyroid hormone production. Many depressed patients also suffered from hypothyroidism. Supplementation with tyrosine increased levels of the neurotransmitter norepinephrine, which increased thyroid hormone release. The tyrosine-supplemented rats not only gained less weight, but also had better cognitive function (as measured in maze tests and distance traveled)

3) Tyrosine Increases Dopamine Levels in the Brain
Tyrosine supplementation increased dopamine levels in the striatum of the brain when animals are given treatments that increase dopamine demand. Tyrosine administration also increased dopamine levels in the extracellular fluid of the brain. However, this effect was short-lived as excessive tyrosine in the brain also slowed down neuronal firing. This, in turn, brought the dopamine levels back to the original levels before tyrosine administration.

4) Tyrosine Helps with Performance During Stress
Tyrosine is a precursor to norepinephrine. Stress reduces norepinephrine levels in the brain (locus coeruleus, hippocampus, and the hypothalamus). When rats were subjected to shock, norepinephrine levels dropped heavily. But, when tyrosine was injected into the rats, the norepinephrine levels remained constant. This is most likely caused by the fact that tyrosine enhanced the rate of norepinephrine production during stressful situations. The added tyrosine caused the rats to show no behavioral deficits while rats that did not get the tyrosine supplements did show behavioral changes resulting from stress. It was also hypothesized that tyrosine may improve physical performance only if the exercise being done produces enough cognitive stress and depletes dopamine or norepinephrine levels 

5) Tyrosine May Improve Attention Deficit Disorders
Clinical trials of using tyrosine to try to improve attention deficit disorder symptoms in humans showed some positive results. Of the 12 adults that volunteered for the clinical trials, eight of them showed some form of clinical improvement in two weeks.However, after six weeks, all eight of the patients developed a tolerance to the tyrosine and improvements stalled. Further investigation into how tyrosine may be used to cure attention deficit disorders needs to be done. Impaired neurotransmitter energy production may be a predisposition for attention deficit disorder. Although this only accounts for 5 to 10% of the attention deficit disorder cases, it is more likely that such cases would benefit more from tyrosine supplementation 

6) Tyrosine to Treat Depression
Tyrosine was found to help depression in certain patients in some clinical trials. A single case, placebo-controlled, case involving a 30-year old woman suffering from depression showed marked improvement after tyrosine therapy. Placebo treatments immediately showcased a return of depression symptoms. Continued tyrosine therapy brought back a marked improvement. Further trials regarding two other patients with depression also showed improvement regarding symptoms . However, larger clinical trial of 65 patients did not support that tyrosine can be used as an antidepressant. Possibly, this was because depression is dependent on many factors, not simply a lack of dopamine or norepinephrine. Tyrosine might only help depression patients with low dopamine and norepinephrine levels

7) Tyrosine for Treatment of Parkinson’s Disease
Nine patients who had Parkinson’s disease were treated with tyrosine and probenecid. These patients showed an increase in homovanillic acid in the cerebrospinal fluid. The presence of homovanillic acid, a product of dopamine energy production, correlates to the fact that dopamine is being released in the brain. Because Parkinson’s is strongly linked to the degeneration of neurons that release dopamine, increased levels of homovanillic acid could be good proof that tyrosine may be used to treat the disease 

8) Tyrosine Improves Inhibition
Tyrosine administration could help reduce unwanted tendencies .One study describes these tendencies as inhibitory control. When patients were asked to perform a stop-signal task (where the patient clicks stop when a green arrow turns red), patients with tyrosine injections performed better than those with a placebo 

9) Tyrosine Improves Mood During Winter Blues
During stressful situations such as the cold or elevated altitudes, increased tyrosine levels improved mood by lowering the intensities of symptoms from the cold and lowered oxygen levels. In a long-term study, patients in Antarctica were given tyrosine supplements daily over the summer and winter. However, during only stressful conditions in the winter months did the tyrosine supplements help to improve mood (by 47%). Summer conditions were not harsh enough to illicit a response.
