Ingredients

What is it that make HTPPY superior to outdated 5-HTP based mood support supplements?

HTPPY was developed by nutritional specialists, based upon the latest clinical research on mood, cognition and the impact of supplementation.

And we don’t hide behind proprietary blends. Feel free to study our full, transparent ingredient list, below. You’ll also discover the studies which supports each ingredient’s inclusion in HTPPY’s custom formulation.

5-HTP

5HTP is a naturally occurring amino acid. It is a precursor to serotonin - the happy neurotransmitter (brain chemical). Low serotonin levels are associated with depression, anxiety, sleep disorders, weight gain and other health problems [1]. We cannot take serotonin supplements directly as they cannot cross the blood-brain barrier. Luckily, 5-HTP is excellent at crossing this barrier and efficiently converts into serotonin [2].

5-HTP is derived from the seeds of the plant Griffonia simplicifolia. Because of 5-HTP’s serotonin-boosting potential benefits, a number of studies have been conducted on it. Several small studies have found that 5-HTP reduced symptoms of depression [3]. 5-HTP can be also converted into the hormone melatonin. As melatonin regulates sleep, it is believed that 5-HTP can also aid restful sleep by boosting melatonin production [4]

L-Tyrosine

L-Tyrosine is another vital amino acid. Without tyrosine your body cannot make the neurotransmitters dopamine (for mood and motivation), nor adrenaline, for focus and drive [5]. Dopamine regulates your reward and pleasure centers. This important brain chemical is also important for memory and motor skills. During periods of stressful or mentally demanding situations, these neurotransmitters tend to decrease [6]

There is good evidence that supplementing with tyrosine replenishes these important neurotransmitters and can improve mood [7] and alertness during times when we’re suffering with a lack of sleep the previous night [8]. It is important to note that dopamine also influences serotonin, and together, the two play a central role in regulating your mood [9]. It’s why HTPPY balances 5-HTP with L-Tyrosine.

Magnesium

Magnesium contributes to more than 300 of your body’s biochemical reactions. However, for all its importance, the World Health Organization estimates that up to 75% of adults in the West aren’t consuming the recommended daily amount of magnesium [10] Amongst its many crucial roles, it is speculated that a deficiency in magnesium may contribute to anxiety [11]. Perhaps this is the reason that magnesium has long been considered nature’s “chill pill”.

And the evidence looks promising. A 2017 review looking at 18 different studies found that magnesium did reduce anxiety [12]. Magnesium is believed to ease anxiety and low mood as it plays a crucial role in converting the amino acid tryptophan into serotonin. A recent 2020 study investigating the combination of tryptophan and magnesium on mood and anxiety concluded that a tryptophan and a magnesium-enriched diet could reduce mood disturbance [13].

L-Theanine

L-Theanine is an amino acid naturally found in tea leaves. L-Theanine promotes relaxation and facilitates sleep by contributing to a number of changes in the brain [14]. By boosting the calming neurotransmitter GABA - which regulates anxiety - studies show it can promote a sense of calm and can aid sleep [15]. L-Theanine has the further advantage of reducing levels of chemicals in the brain that are linked to stress and anxiety [16].

Perhaps the most useful attribute of L-Theanine is that it works to relax without sedating. This is achieved by L-Theanine’s effect on enhancing Alpha brain waves. Alpha brain waves are associated with the state of mind you experience when you’re meditating or daydreaming. This ‘wakeful relaxation’ gives L-Theanine an advantage over traditional anxiety-reducers such as valerian or hops, by removing the worry of becoming sleepy during the day [16]].

Zinc

Zinc plays a part in over 100 of your body’s functions - including regulating the immune system. As the body cannot store zinc, we must get it from our diet or supplementation. One of the signs of zinc deficiency is mood swings (mental lethargy) and anxiety. Therefore, new research suggests supplementing with zinc might help promote better mood in people that aren't getting enough in the foods they eat [17].

A recent study supplemented young women with zinc. The women reported reductions in depression and anger [18]. Zinc deficiencies are also associated with reduced ability to produce testosterone - a hormone associated with mood in both men and women [19]. Scientists believe that the relationship between zinc and mood may be explained by zinc helping to boost the production of the calming neurotransmitter GABA to aid anxiety symptoms [20].

Vitamin D

Vitamin D is known as the sunshine vitamin. Yet despite the ubiquity of the sun, 1 billion people are estimated to have a Vitamin D deficiency [21]. In autumn and winter, when sunlight becomes scarce, as many as 1 in 5 Brits are found to be lacking in Vitamin D - which is why Public Health England recommends Vitamin D supplementation. As well as building strong bones, there is evidence of lack of Vitamin D correlating with low mood [22].

It certainly seems to make sense. Don’t we all feel better outside in the sunshine? Some researchers now suggest that the decrease in vitamin D production caused by reduced sunlight during the winter months may be a factor in seasonal affective disorder (SAD) [23]. And according to one clinical research paper, even very short-term supplementation of D3 can enhance mood [24]. Which is why each daily serving of HTPPY contains 1000IU of Vitamin D.
